My review of "Burning in the Sun" - I loved this unique eco-documentary

"Burning in the Sun" featuring Daniel Dumbele. Note the film-festival awards across the top.

My husband loped into the living room while I was watching the DVD, "Burning in the Sun". He had hoped to turn on a baseball game, but he stopped, watching a scene on the DVD. After a minute, he sat down.

"What's this?," he asked me.

"It's a documentary I was asked to review," I told him. "It's the best film I've seen about solar since Jeff Barrie and 'Kilowatt Ours'. About this young guy in Mali who makes solar panels by hand and distributes them to villages that have no electricity. It's really good."

Ken stayed and watched the whole thing with me.

Charismatic Daniel yearns to help his country
"Burning in the Sun" is the most memorable environmental documentary I've seen in a while. But it's also a compelling personal story that would be interesting even if the star, charming Daniel Dumbele, were selling shoes instead of PV panels. It's a plug for non-polluting, affordable solar power, but it's also about parental influence, about youth struggling for meaningful livelihood, about West African rural culture - all of which are fascinating to me.

Can't help but love this lad: equal parts European and West African
Daniel was raised in Mali by his European mother after his West African father died. Growing up, Daniel helped his mother install 350 wells throughout inpoverished rural Mali, saving lives by providing clean and safe drinking water. Said Daniel, "For me, it's nice and normal to be trying to help my people." At the age of 26, Daniel decided to start his own project: he learned how to make solar PV panels for $200 instead of the usual $1000, by piecing together broken PV cells discarded by American corporations. He uses all local materials to make the panels, except for the broken PV cells he carefully trims and fits together like puzzle pieces.
Daniel hoists a panel he made to a rooftop in Mali

As the DVD unfolds, Daniel sets out to distribute the completed panels, with more requests for them than he can fill. He focuses first on the village of Banko, holding a workshop for local people to teach them how to install the panels and set up the wiring. He's assisted in the beginning by a solar physicist and a female solar engineer, as he masters the circuitry for getting energy from the panel to the lightbulbs - which turns out to be quite simple. Click here to see a film trailer.

Daniel's panels profoundly affect students' exam results
After Daniel's efforts, the school in Banko is illuminated for the first time, and the students (girls and boys) flock into the brightly lit room in the evenings to do their homework.  The film tells us that the year before getting lights, only 20% of the Banko children passed their national exams. The year after, 97% passed!

Micro-loans make panels affordable
Daniel explains that he plans to sell the panels in the city, where customers will have to pay him cash. Then he will be able to offer "micro-credit" or "micro-loans" to the rural villagers, most of whom are farmers, allowing them a year to pay him back for their panels. Or even allowing them to barter for the panels.

Daniel finds a way to help the world while supporting himself  - a feat that still eludes me
The documentary caught Daniel at precisely that point in this life where he's trying to figure out how to help his people in his own way, while at the same time making a living. As a mother of two twenty-somethings myself, I was moved by Daniel's search for livelihood. I also know from my own struggles that it's not easy to make a living by serving a cause. I still haven't figured out how!

Afriq-Power attracts big clients
Daniel is making it work. In 2006, his company "Afriq-Power" opened a storefront in Bamako, Mali's capital city. His clients now include USAID, Geekcorps, and the US Embassy. Daniel's company electrifies health centers and schools, and installs solar-powered pumps in rural Mali. Daniel recently won a $30,000 contract to build 400 panels to power radios in Malian villages.

Ken's students were intriqued by the DVD
As I watched the captivating story of Daniel's journey, my husband Ken was sucked into it too, and forgot all about the baseball game he'd intended to watch. Ken was so enraptured with the DVD, he watched both versions (83 minutes and 22 minutes), and then took the film to work to show his classes. The next evening he told me that it had sparked class discussions about the association between the education of girls and reduction of birth rates, about the concept of microloans, about the diversity of races at work on the project and the inclusion of both genders as solar "experts". Most of all, after studying global poverty in the abstract, his students really enjoyed the personal nature of "Burning in the Sun." Me too!

I strongly endorse this film
I recommend this inspirational and informative documentary to anyone - for personal viewing at home, to fuel family discussions, to illustrate multiple issues to students - poverty in developing nations, grass-roots solutions to our environmental crises, communities working together learn new technologies. "Burning in the Sun" is perhaps the most fully-fleshed out documentary I've seen yet - a very human story about the monumental problems that threaten our planet.

Orangutans on Borneo are observed using tools to catch fish

Mother and baby orangutan at a refuge on Borneo. Photo: Sally Kneidel

Field researcher Anne Russon of York University in Toronto monitored orangutan behavior from 2004 to 2007 on the Indonesian island of Borneo. She observed orangutans scavenging fish that had washed up along shores. She also saw them grabbing live catfish out of small ponds. The orangutans immediately ate the fish.

In 2007, Russon stocked a small pond with catfish and videotaped orangutan visits to this pond. She reported that several of the red apes learned on their own to jab at catfish with sticks, provoking the fish to flop out of the ponds within reach. The orangutans then ate them.

Using sticks to frighten fish out of ponds qualifies as "tool use," an ability that was once thought to be unique to humans. Other primates and crows have also been observed using tools to obtain food, and sometimes making tools. Chimps have been filmed making spears to stab and remove small primates from treeholes and then eat them. (The spears are made by sharpening sticks with their teeth.) Chimps also use sticks to remove termites from holes to eat.

If any of you readers can tell me other observations of meat-eating or tool-use in orangutans, I'd like to know.

Russon reported her observations of orangutans catching fish at the 'American Association of Physical Anthropologists' meeting in Minneapolis on April 14, 2011.

We took a stand against Duke Energy's nukes and coal

Dozens of protesters demonstrated outside Duke Energy headquarters in Charlotte on Thursday (5/5/11), prior to a meeting of shareholders.  The demonstration included speakers, picketers with signs, and street theater - the actors portrayed utility customers whose money winds up in the hands of legislators.  The demonstrators protested the use of coal from mountaintop removal and the construction of two new nuclear units in Cherokee County, S.C.

The most eloquent speaker I heard was Mickey McCoy (above), a Kentucky native who grew up in a town devastated by mountaintop removal. Jim Rogers said Duke tries to avoid buying coal extracted by mountaintop removal, but only when they can find other coal sources that are equally cheap (unlikely since mountaintop removal is the cheapest method).

At the shareholders meeting indoors, 20-30 people lined up microphones in the aisles of the auditorium to pose questions to Duke Energy CEO and President, Jim Rogers. I was one of those people - my purpose was to point out to Rogers and the shareholders the risk involved in building new nuclear units in South Carolina, on a river whose flow is inadequate to provide consistent cooling of the units.

My comments to CEO Jim Rogers at the meeting:
"I'm concerned about the consumption of water by the proposed nuclear units on the Broad River. Duke Energy and its shareholders face serious financial and public relations risks from Duke’s use of so much water.

"Already, NC’s electric-production sector has one of the largest rates of water withdrawals in the nation, over 9 billion gallons every day – about 80% of our state’s total water withdrawals.


"I understand that some of the water withdrawn by nuclear power plants is returned to the lakes it’s drawn from. But much of the water withdrawn to cool the reactors is 'consumed' or lost by evaporation. The proposed units on the Broad River will have a consumptive loss of 35-40 million gallons per day.


"Right now, most people are unaware of how nuclear plants impact our state's water - including loss of aquatic habitat, releases of radioactivity, and the huge evaporative losses. As you [Jim Rogers] said yourself, 'water is the new oil' – because of growing water shortages due to population growth and climate change.


"Soon the people of NC will find these losses of water and habitat unacceptable. Duke will be taking a huge risk to squander even more water at new nuclear plants. Likewise, with 70% of biologists predicting mass extinctions this century, the loss of aquatic wildlife due to dams and thermal pollution will become increasingly objectionable to the public.


"The increasing water shortage also creates a high financial risk for Duke. Because of coming droughts and periods when water is too warm to cool the plants,the proposed plants are likely to be idle at times or operate at reduced power - a public annoyance and a loss of revenue.  As the Broad River diminishes over the years, the useful lifespan of the $11 billion units is also likely to be cut short. So the ratepayers [not the shareholders] will wind up paying for nonfunctional nuclear plants.


"Do you, Mr. Rogers, believe the Broad River will have enough water to support these plants?


"In other states Duke is investing more aggressively in energy efficiency, wind, and solar, which require no water. Why doesn’t Duke invest more in efficiency, wind, and solar here in its home state, thereby minimizing the risks to Duke and to all North Carolinians of our dwindling water supplies?"


Rogers' response
Jim Rogers answered my question about the Broad River by saying "That's a good question." He went on to say that Duke is studying the issue and they plan to create a reservoir (by damming the Broad River). Which was no answer, really. Every nuclear plant has a reservoir of some kind. The question about solar, wind, and efficiency was posed by several people. He said wind turbines take up too much room. The real answer to the efficiency question is that Duke makes more money when customers consume more energy, because then they pay more money to Duke. Duke had strong 2010 earnings, and this past week had first-quarter growth that moved its stock to the highest price in 3 years.

April tornadoes caused by climate change, population growth, and pavement

Photo: noaa.gov

April's 297 devastating tornadoes were unparalleled in the U.S. Of the four biggest tornado clusters ever recorded here, two occurred this past April. What caused so many deadly and tragic tornadoes in a single month?

Meterorologists say chance is partly to blame. One little thing can set off a tornado, or not.

We do understand a lot about factors that cause tornadoes, though. They need warm, most air interacting with cooler, faster air. A thunderstorm coupled with something to create rotation, such as wind shear, can create a tornado. Are those conditions occuring together more often these days?

Changing climate is partly a factor, say meteorologists. Jet stream forces in April were among the strongest ever recorded, contributing to wetter, stormier weather than usual in the middle of the country. (I wrote a post recently about how warming Arctic air has sent the circumpolar jet stream shooting off southward, leading to the massive snow falls the U.S. experienced this winter.)

The stormier April was also caused in part by warm air from the U.S (warmer than usual due to climate change) colliding with cooler Canadian air - conditions that can spawn tornadoes.

Population growth and pavement contribute to number of tornadoes

More people are living now in "Tornado Alley" - the nation's midsection and the South - so more tornadoes are observed and recorded.

Some of the states hit hardest by tornadoes this year were also among our fasted growing states - such as Texas and North Carolina. The South has grown 14.3% in the past decade, compared to 9.7% for the nation as a whole. According to Kirk Johnson of the NYT, much of that growth occurred in areas of flood plain, where water used to spread out and be absorbed. But now that the areas are developed and paved, water runs off quickly, heated by the pavement, and is much more likely to cause floods of warm water. The evaporation of warm water can lead to storms, and collisions of air masses of different temperatures and densities. Ingredients for tornadoes.

Climatologists have long predicted that climate change will lead to stronger storms as we head into the future. Apparently that will include not only hurricanes, droughts, blizzards, and floods, but also tornadoes.

Older female elephants assess danger best

Male lions are deadly predators. A single male, alone, can bring down an elephant calf. Females can't do it alone - more than one female lion is needed to attack any elephant successfully. So, from an elephant's perspective,it pays to be able to tell who's on the prowl - a male or female lion, and how many.

Karen McComb and her team from the University of Sussex in Brighton, England, played lion calls to 39 elephant families in Kenya's Amboseli National Park. They compared the elephants' reactions to the lion roars. All the matriarchs reacted to the sound of three lions roaring with more agitation and avoidance than the sound of one lion. But the older matriarchs showed an additional awareness - they could tell not only the number of lions, but the gender of the lions, and respond to the different threats accordingly. McComb's research will be published in an upcoming Proceedings of the Royal Society B.

Females over 60 are best judges of predatory threat
The researchers concluded that an older, more experienced leader would be likely to make a more accurate assessment of the relative danger from nearby lions(s). A young and aggressive leader can be an able defender, even though lacking the accumulated social and ecological knowledge of an elder. A combination of a young aggressive leader and an older experienced matriarch may be the ideal combo to head up a pride of lions.

Sadly, poachers often target bigger and older elephants. This practice poses a more serious threat to the elephants than would the poaching of younger individuals. The repercussions of poaching older elephants has broad implications, far beyond predatory threats. Elder elephants also model appropriate social behavior to younger adults and adolescents. The loss of elders can lead to out-of-control behavior in young rogue males, which have been documented behaving destructively and overly-aggressively. Their asocial behavior has included the rape of rhinoceros species.

Orangutans are lefties, chimps and gorillas right-handed

Photo showing an orangutan engaged in the TUBE task. Photo used with permission of the researcher  William Hopkins. 

Mmm, love that peanut butter
Apes are right-handed or left-handed, just like us. Not a big surprise, since they're our closest evolutionary relatives. A research team led by William Hopkins of Agnes Scott College recently tested 777 captive apes  - orangutans, gorillas, chimpanzees, and bonobos. Each ape was given a PVC tube 15 cm in length and 2.5 cm in diameter, with peanut butter smeared in both ends. The peanut butter was too far inside to reach with their mouths. The apes had to hold the tube with one hand and reach inside with a finger of the other hand. The researchers recorded which hand the apes used to reach inside for the peanut butter.  Each ape was tested on 2 to 4 occasions, in solitude if possible.

Only the orangs were left-handed
Orangutans turned out to be the only southpaws. The majority of gorillas and chimps are right-handed, as are 90% of humans. Bonobos showed no significant handedness at the population level. Hopkins believes that handedness at the population level in apes may be a result of ecological adaptations associated with posture and locomotion (personal communication with Hopkins).  He plans further research to try to understand why orangutans are left-handed, while other apes and humans are right-handed in general. It may be somehow related to the fact that orangutans are the most arboreal of the apes.

Hopkins' research will soon be published: Journal of Human Evolution 60 (2011) 605-611.

Handedness in crows too
Apes are not the only nonhumans to display handedness.  In 2007 I wrote this post about research by Gavin Hunt of the University of Auckland, who documented handedness and tool-making in New Caledonia crows.

The Meaning behind "Earth Hour"

During the last Saturday of March each year between 8:30 and 9:30 p.m. people and businesses around the world pledge their support to reducing environmental impact by turning off their lights. This year, that date was March 26, and approximately 134 countries did their part by pulling the "off" switch, which plunged some of the world's most iconic structures into temporary darkness. The Petronas Twin Towers in Malaysia disappeared from the night sky. The Eiffel Tower in France completely winked out. The Burj Kalifa in Dubai, the tallest tower in the world, seemed to suddenly vanish into thin air. All of this reminded people that the impetus for environmental change is everywhere, but that only through collaboration can the planet be saved.

Earth Hour began four years ago in Sydney, Australia, where 2.2 million people and more than 2,000 businesses shut off their lights for an hour to demonstrate their commitment to environmental change. Since then, the message of Earth Hour has gone global. Unlike many other demonstrations for change, Earth Hour is also a celebration. Many participants in Earth Hour throw parties, showing that doing something to help the planet does not have to be all work and no play. As only non-essential lights are turned off, such as building lights and room lights, public safety is not a concern as long as participants stay aware of their surroundings.

This year's Earth Hour was a success with some of the world's largest cities taking part, including New York, Hong Kong, Toronto, and Moscow. Yet, it was the 2010 Earth Hour that remains the event's most successful year. In 2010, approximately 4,616 cities, towns, and municipalities took part in Earth Hour, and about 1,551 iconic landmarks went dark as well.

Yet, despite all of Earth Hour's accomplishments, there have been critics. These critics typically claim that the hour-long absence of lights does not make a difference in terms of energy consumption and its effects on the environment, and this claim is undeniably true. In the grand scheme of things, turning off lights for one hour every year does not make much of an impact. However, this annual event is not about turning off lights to save power. Instead, it is a symbol of environmental change rather than an act of environmental change. It allows communities and businesses to come together for an easy and visually stunning representation of what it means to use less in order to give more back to nature.

Failure is a part of success

In this video Michael Goodwin proposes that without failure, success loses its meaning. I've certainly heard this message for years from my father, who is a high school biology teacher. Over the 25 years he's spent at his school, I've heard him rant countless times about pressure from parents and even school administrators to award As and Bs to all his students - even those who haven't earned them - so they'll have good-looking transcripts for college. The result of this, he points out, is that those grades become meaningless. And what's more, the grading system is no longer a motivation for students to succeed. Why offer grades at all if they're all the same? Furthermore, I'd argue that this issue starts long before the classroom. When I'm playing with my housemates' two-year-old, I frequently feel compelled to intervene before she does something silly. "You can't fit your dolls into that box! It's too small." "You can't wear that shoe! It's too big for you." But I try to restrain myself from offering these comments. She learns much faster from trying - and failing - to do these things than she does if I tell her what to do. Yesterday I watched her trying to make a tower out of a set of nesting plastic cups. She didn't understand that she had to stack the cups according to size in order to make a tower. But I said nothing and watched her try and try. She gradually observed that if she put a small cup first, the larger cups just covered it up. After several minutes of trying she rearranged the cups and successfully built a tower!


When I tell her what to do, in order to prevent failure, she usually gets upset and loses interest in the activity. But when I let her figure it out on her own, she feels accomplished and proud. Working through failure increases learning at all stages of life and is necessary to really learn from success.

Trade a major threat to primate survival

Tens, if not hundreds, of thousands of primates are traded every year, and the number's been growing linearly for 15 years When I read that news in a recent study by Vincent Nijman of Oxford Brookes University, I was not surprised. Having worked and traveled in Africa, the Amazon, and S.e. Asia, I've seen for myself that legal and illegal trade in primates is rampant. I've communicated with Nijman several times over primate issues; he seems to be one of the most knowledgeable academics alive on the subject of primate trade in S.e. Asia (and maybe elsewhere as well).

Nijman's article ("Primate conservation: measuring and mitigating trade in primates") is the overview article to a new issue of the open-access journal Endangered Species Research. This particular issue is the result of a recent conference and is devoted entirely to primate conservation. In Nijman's introduction, he and co-authors write that the international trade in primates -- for research, pets, meat, etc.-- is one of the biggest threats to primate conservation. Habitat loss and hunting are the main threats to primate survival in the wild, but trade is a leading threat for some species, such as the slow loris and Barbary macaque.

During the 1990s, numbers of wild-caught and captive-bred primates traded were roughly equal, but afterward captive breeding increased substantially.  By 2005, around 71,000 live primates were traded internationally, 53,000 of them reported as captive-bred. However, some of the captive-breds may have been laundered wild-caught specimens.

Since 1995, China and Mauritius have supplied more than half of all primates traded internationally (31% and 18% respectively).  And guess who is the largest importer of live primates? I'll give you a hint - a country with thriving medical research and a poorly regulated pet trade.  Yep, the US imports the most live primates (26%), with Japan (14%) and China (13%) close behind.

Although I knew about the trade in live primates, I was shocked to read in Nijman's paper that more than a million dead primates are traded every year. The trade in dead primates and primate parts includes almost 20,000 exported as hunting trophies over the past 30 years.

The dead also include more than 100 primate species used in traditional medicines (based on cultural superstitions).The journal mentioned above contains a paper by Starr et al. documenting the threat posed to two slow loris species in Cambodia from such trade.

However, the major trade in primates is in those traded domestically for food. A paper by Wright and Priston in this same special issue examines what drives such trade in southwestern Cameroon and concludes that many more primates are sold there for wild meat than are captured for local consumption.

Examples of illegally traded primates include long-tailed macaques from mainland S.e. Asia (Cambodia, Laos, Viet Nam) into China, to supply the booming biomedical trade. A paper in this special issue by Maldonado and co-workers documents the illicit trade of over 4,000 night monkeys (Aotus spp.) each year from Peru and Brazil into Colombia to supply a biomedical research facility.

“The above figures are from an analysis of legal trade reported to CITES [the Convention on International Trade in Endangered Species of Wild Fauna and Flora], but the true figures are likely to be higher, because of under-reporting and illegal trade,” says Nijman.

As Nijman et al. note, in 2006, trade was listed as a threat to only one of the world’s most threatened primates species, but four years later, trade for meat, medicines and pets is implicated in the decline of nine of these species.

Other papers in the special issue include one by Chris Shepherd of TRAFFIC Southeast Asia on the illegal primate trade in Indonesia.  He also contributed as a co-author to an article on gibbons in zoos and rescue centers in Indonesia. Chris is an impressively diligent and persistent wildlife-trade researcher and writer for TRAFFIC in S.e. Asia.  He was a big help to me in preparing for my own travels there.

“The illegal primate trade in Asia is decimating populations of some of the region’s most charismatic species: tackling such trade should be regarded as an urgent priority for wildlife enforcement agencies in the region,” said Shepherd.

Other topics covered include effective implementation of CITES; the use of forensics in trade; problems, pitfalls, and successes of rehabilitating and reintroducing confiscated primates; and educational and livelihood strategies to mitigate trade.

Radiation found in Japan's food exceeds safety levels

Tests performed Saturday food supply found radiation in spinach from farms six 60-75 miles south of Japan's stricken reactors. Radioactive iodine in the spinach exceeded government safety levels three to seven times, reported food-safety officials. High levels of radioactive iodine are linked to thyroid cancer.

Milk at a dairy 20 miles from the leaking reactors was found on Wednesday to contain small amounts of iodine-131 and cesium-137.

The milk and spinach are from an agriculturally rich area, so the radioactive contamination could affect the food supply for large areas of Japan. Chief Cabinet Secretary Yukio Edano said that more tests are being done on other foods, and if more contamination is found, food shipments from the area will be halted. He also insisted that the contaminated foods "pose no immediate health risks".

More than 7,600 people were killed by the earthquake-spawned tsunami that knocked out the nuclear reactors. More than 11,000 people are still missing.

Radioactive isotope from Japanese reactors detected in Sacramento

The EPA reported Friday afternoon that a small amount of radiation from Japan's damaged nuclear reactors has been detected in Sacramento.  Experts have been expecting small amounts of radioactive isotopes to blow over the ocean to California beginning as early as Friday. The isotope picked up by monitors Friday is xenon-133. According to the EPA, the isotope is present in Sacramento at such low levels that it presents no danger to human health.

Lions decline 90-95% in last 50 years

Lions extinct in 10-15 years? That's the prediction of National Geographic explorers-in-residence Dereck and Beverly Joubert. The couple have studied and filmed Africa's big cats for more than 25 years. They say that wild lions have declined from 400,000 in 1960 to around 20,000 today.

"The Last Lions"

Based in Botswana, the Jouberts have a new documentary and a companion book, both called "The Last Lions" (see link below). This latest film follows a solitary female lion in the Okavango Delta of Botswana as she tries to feed and protect her three cubs after her mate dies. Female lions usually live and hunt in a group, with a single male as protector against intruding males. A solitary female alone is at a serious disadvantage. Females do virtually all the hunting for a group, and they usually hunt cooperatively.

Males are freeloaders

Males that are part of a pride seldom hunt, but share in the females' kills. The conspicuous black mane helps protect a male's neck during fights with rivals, but makes it difficult for him to creep toward pray unnoticed.  Mortality is much higher in males than in females.

Threats to lions

Africa's lions are threatened primarily by habitat loss, as human populations expand. They're also frequently poisoned or trapped by rural dwellers who blame lions for livestock losses.

I was surprised at how few lions I saw

I've been to South Africa a couple of times in the last 5 years looking for wildlife.  Although I spent virtually all my time in Kruger National Park and other wildlife reserves, I saw very few lions.  In eight weeks of searching, I had only three lion sightings: one solitary male, two males on a kill together, and one pride of females with their young. One wildlife guide I talked with told me that, in his youth 40 years earlier, he had shot lions every single day - to protect his family's livestock, he said. This was in the same place where I saw only one lion over a period of 3 weeks.

Duke Energy fuels the extreme weather that drives up our bills


This letter to the editor was written in response to "Scientists connect global warming to extreme rain" (Feb.17) and "Duke earnings up 23% in 2010" (Feb. 18)

"Thursday the Observer reported that 'telltale fingerprints' in scientific data confirm that manmade climate change is fueling extreme weather events such as massive snowstorms and rainstorms. Friday we learned that Duke Energy's 2010 earnings were up 23 percent, in large part because of extreme weather.

"Now, Duke Energy wants to raise rates to pay for new coal-fired power plants. Burning coal is a huge cause of the climate crisis. Climate change is not a "victimless crime." Extreme weather hurts people. But it's great for Duke Energy.

"Let's call on Duke Energy to stop fueling the extreme weather that's driving up our electric bills and Duke's profits. Duke should shut down some coal plants and promote drastic conservation and energy efficiency."

We are family: new evidence of our close link to chimps

Photo: wikimedia commons

People are good at detecting human personalities accurately, even from expressionless mug shots. A study last year showed that we can reliably tell who is extroverted, emotionally stable, agreeable or imaginative - just from their blank and expressionless faces.

We can read chimps too

A new study shows that we can also predict personality traits accurately from expressionless photos of chimps!  In the new study from Bangor University of Wales, 139 college students looked at pairs of chimpanzee mug shots.  In the photos, the chimps looked straight ahead or at a slight angle with no teeth showing and no shadowing over the eyes which could make them look threatening. Sixty to 70% of the students accurately identified which chimps were dominant and which were not.  Accuracy was better with male chimps than females.

The researchers, led by Robert Ward, say they don't know exactly what characterizes the face of a dominant chimp or an extroverted person. Ward suspects that chimps can detect the difference too.  He plans to test that next.

Study underscores our genetic similarity to chimps

What's the significance of these studies? The researchers conclude that the ability to detect important personality traits from facial structure (not expressions) evolved 7 million years ago in a common ancestor of both chimps and humans.  The fact that humans can read chimp facial expressions suggests that this ability is "part of an evolved system."

Chimps are our closest relatives, sharing 98% of the our DNA. It's not too surprising that we should able to read their faces in the same way we read human faces.

Wouldn't it be nice...

I'm always glad when I see a study like this.  I have this fantasy that once we realize how smart and how like us chimpanzees and other great apes are, the tide will turn on protecting our ape relatives from impending extinction.

New study: Women's tears contain pheromones that turn men off

 
Female tears affect men's desire. Photo: wikimedia commons

An old friend told me once that she intentionally cries in conversations with her husband when she's not getting her way.  She might want to consider a different tactic.  New evidence suggests that a pheromone in women's tears turns men off rather decidedly.

Two researchers at the Weizmann Institute of Science in Israel have just published a study in the journal Science which demonstrates that the tears of human females turn men off.

Tears contain pheromones, apparently
The researchers, Shani Gelstein and Noam Sobel, have apparently shown that human female tears contain a pheromone that reduces men's sexual arousal.  A pheromone is a chemical produced by the body that communicates with others of the same species. For example, female dogs in heat have a scent that attracts males. Males of many species have a scent in their urine, or in glandular secretions, that advertises the boundaries of their territories and keeps competitors out.  Pheromones are very common among other mammals but have seldom (if ever) been identified in humans.

It's interesting that, in this experiment, the subjects could not consciously smell the pheromone. But they apparently smelled it subconsciously, because it affected their behavior.


Women's tears dampened men's sexual response
I thought the experiment was ingenious.  The researchers collected a jar of tears from women as they watched sad film clips and tears trickled down their faces. A pad containing either tears or a salt solution that had been trickled down the same faces was then attached to each male subject's upper lip.  Neither substance had a perceptible odor.  The men were then shown female faces; 17 of the 24 men found the female faces less alluring after whiffing tears than after whiffing salt solution.

Another 50 men showed less physiological sexual arousal after whiffing tears than after whiffing salt solution. Low sexual arousal was indicated by slow breathing rates and low levels of testosterone in their saliva.

In a final experiment, men watched a sad movie while sniffing women's tears or sniffing a salt solution. The men sniffing tears showed a much reduced blood flow to areas of the brain that had earlier reacted strongly to an R-rated erotic movie.

The researchers don't know what the chemical nature of the pheromone might be.  More research is need to figure that out. 


How would the pheromones in women's tears affect other women?
I never have really felt that it was to my advantage to cry in front of a man. It might catch attention, might inspire guilt or pity, but I'm not sure it's ever really worked to my advantage. I'm curious to see the experiment repeated on female subjects.  How do females respond to whiffing the tears of other females? I imagine the response would be increased blood flow to the parts of the brain involved in care-taking, nurturing, and heart-felt sympathy.

What do you think?

Massive snowfalls due to Arctic warming, breakdown of polar vortex

 Photo by Sally Kneidel

Why are massive snowfalls and cold air walloping the U.S. for the second year in a row?

I listened to the climate reporter for the NY Times, Justin Gillis, on NPR yesterday. He said our current weather is due to a breakdown in the "polar vortex." Gillis mentioned that the U.S. had warmer winters up through 1995 - thought to be due to global climate change. Now record-setting blizzards are dumping massive amounts of snow over large areas of the U.S. And that too is thought to be due to global climate change. Does that make sense? It does.

This morning I read the newsletter of Thomas Homer-Dixon, a climate scientist in the U.K. He explained what the polar vortex is, how the melting of Arctic ice has changed it, and how that change is responsible for our brutal winter.
Even areas of the South have had multiple snowfalls this year. Photo: Sally Kneidel

What is the "polar vortex"?

Dr. Homer-Dixon explains it this way. Usually in early winter, a basin of low-pressure air forms over the Arctic Ocean's cold sea ice. Jet streams travel west to east along this basin's southern edge, creating a huge circular flow - the polar vortex - that travels counterclockwise around the Arctic. This flow acts as a fence, separating the Arctic's cold air from warmer air farther south.

A warmer Arctic apparently causes colder continents

According to Homer-Dixon and other climate scientists, heat was released last winter (in Dec and Feb) by newly exposed water in the Arctic - water that used to be ice. That heat created bulges of high-pressure air over the Arctic which pressed against the polar vortex, destabilizing it. The jet streams that comprise the polar vortex broke into disconnected segments, some of which traveled north to south, pulling bitterly cold air into North America, Europe and eastern China.

That change in wind directions is called the "Warm Arctic - Cold Continents" climate pattern.

Scientists can't say for sure yet whether the same thing is responsible for this year's brutal winter. But they do know that jet-stream maps for the Northern Hemisphere in late November 2010 showed the jet streams broken into "bits, pieces, loops, and circles with many north-to-south flows over North America and Eurasia."

Writes Dr. Homer-Dixon, "People who think this winter's brutish weather proves climate change isn't real might want to think again."

Africa's big mammal populations drop 59% in 40 years!

Just saw a distressing news item.  In an interview published 1/27/11, scientist Ian Craigie says populations of big mammals in Africa have decreased 59% in 40 years. And those figures are only from protected areas such as national parks. If unprotected areas were included in the study, the percent would probably be much higher.  Craigie is a zoologist (University of Cambridge) and former employee of South Africa National Parks.

Craigie says the primary causes of the decline are agriculture, hunting and the bushmeat trade. But all are due to human actions and Africa's population explosion. Africa's human population has increased 5-fold since WWII. The additional human population has moved into cultivated areas that were previously wildlife habitat, leading to widespread habitat destruction.

I might add (my words, not Craigie's) that deforestation for agriculture and timber has increased access to previously secluded or inaccessible wildlife.  Modern weaponry has also increased the ease of killing large numbers of animals for commercial trade as bushmeat or traditional medicine.

Craigie says that Southern Africa is better off than West Africa or East Africa because the parks in Southern Africa have better funding and the human population is less dense.

West Africa has the most serious wildlife problem of the three regions because of the strong tradition of hunting for bushmeat, the countries are poorer, and the human population density is high.

What's the solution? Increase funding for programs to help communities develop livelihoods that depend on protecting wildlife (such as ecotourism) rather than over-harvesting and destroying their greatest resource (wildlife) and their greatest potential for income.  These are my words, not Craigie's.  Americans alone spend 12 billion dollars per year on ecotourism in Africa.

New study: Hope for polar bears

Two-thirds of the world's polar bears could disappear within 50 years due to greenhouse-gas emissions, said a 2007 report by the U.S. Geological Survey. The bears need Arctic sea ice in order to hunt the seals and other offshore prey that sustain them. But our warming climate is rapidly melting the vital sea ice.  Between 1979 and 2010, Arctic sea ice cover decreased by an average of 11.5% per decade. Due to loss of ice, many bears are starving to death already. The polar bear, Ursus maritimus, is now officially listed as "threatened."

A team of scientists stationed in Alaska may have some tentative good news, though. They just published a new assessment of polar bears' future in the Dec 16 (2010) edition of the journal Nature. Steven Amstrup, senior scientist with "Polar Bears International," and his team reported five possible scenarios for greenhouse-gas emissions and ice melting this century. The researchers concluded that Arctic sea ice may not necessarily reach a catastrophic "tipping point" that would lead to an inevitable disintegration of all the ice.  The future of the bears' ice depends on how much we can limit greenhouse-gas emissions in the years to come and how much we can stabilize the climate. One factor in the bears' favor is that thinner ice (as it diminishes) becomes more responsive to the cold water below it and can more easily regrow in winter.

Amstrup's team used climate modeling to predict "sea ice habitability" for the bears over the coming decades, an index that includes the amount of ice over the shallow waters (continental shelves) where seals and other prey hang out, the number of months per year those waters are covered with ice, and the distance between that ice and the more northerly pack ice where polar bears also hunt (there's a limit to how far polar bears can swim from one ice mass to another).

Says Amstrup, “There’s a widely held perception that nothing can be done to help polar bears and the arctic ecosystem. Our findings show this isn’t true. Our findings offer a message of hope but they also underscore the urgent need for reductions in greenhouse gas emissions. ”

South Carolina dog knows more than 1000 words, says NY Times

A retired psychology professor has taught his dog 1022 nouns as well as several verbs, reports the New York Times. Dr. John Pilley set out to beat the record of a German border collie that had learned to recognize 200 objects. Pilley, who taught at Wofford College for 30 years, read about the German dog in the journal Science in 2004. He bought his own border collie, Chaser, as a puppy in the same year. They've been working together four to five hours a day ever since.

Border collies are among the smartest of dogs. They're working dogs, bred to herd sheep, and have a strong instinct to work and to learn commands from humans. Pilley says Chaser seems to love the lessons and always wants more.

Chaser's lessons

To teach Chaser the name of an object, Pilley shows it to Chaser, says the name of it up to 40 times, then hides it and asks Chaser to find it, while repeating the name over and over. For the first few years, Pilley taught Chaser 1 or 2 new names a day, and continued to reinforce any names she had forgotten.

Within 3 years of starting the lessons, Chaser had learned the names for 800 cloth animals, 116 balls, 26 Frisbees and a collection of plastic objects.  When the dog had learned 1000 names, Pilley decided to begin exploring other aspects of language than just nouns. He has demonstrated now that she also has the capacity to understand verbs. (This isn't surprising, given that a sheep herder's commands to his border collie are often verbs directing the dog's actions.)  Chaser  quickly learned to either paw, nose, or take an object in response to Pilley's commands, demonstrating that she understands that verbs have meaning.

Chaser has also learned categories. For example, she knows that "Fetch a Frisbee" means any of her 26 Frisbees, or "Fetch a ball" means any of the balls.

She can also identify a new object by exclusion - selecting it from among objects that she already knows.

Visual cues ruled out

Pilley has confirmed Chaser's vocabulary in settings where she can hear him but can't see him. This rules out the use of visual clues, such as facial expressions or subtle gestures, that could tell Chaser when she has the correct object. Border collies have been bred to be especially observant of gestures because they are part of the communication between a herder and his or her dog.

Pilley's findings to date are reported in the current issue of the journal Behavioural Processes. The retired professor says he's continuing to work on grammar with Chaser, and developing ways to improve communication between people and dogs.

Juliane Kaminski, part of the research team that worked with the German dog (Rico), says that demonstrating syntax would be interesting.  Syntax would include recognizing that changing the order of words can change the meaning of the sentence.& (As in "Bite cat" versus "Cat bites.")

Chimps and gorillas use American Sign Language

There's been a lot of research on teaching language to other animals. Chimps and gorillas lack the vocal anatomy to talk, but they can use their hands to make signs.  I worked with Dr. Roger Fouts at the University of Oklahoma teaching American Sign Language to a small colony of chimpanzees. The chimps lived on a small island at the Primate Institute. Fouts was a pioneer in this field, along with his mentors, the Gardners, at the University of Nevada. The Gardners were the first to teach a chimpanzee (Washoe) to communicate with ASL. Dr. Penny Patterson was the first to teach a gorilla (Koko) to use ASL.

Alex the African Grey Parrot impressed language scientists

Parrots have also demonstrated abilities to learn and understand human language. Alex the African Grey Parrot was the most of parrot pupils. Dr. Irene Pepperberg taught Alex to name colors, shapes, to count small numbers, and to speak around 150 words that he could put into categories. Of course parrots can vocalize, although most birds that speak human words have no idea of the meaning of what they're saying.

Dogs and touch screens?

Dogs are different in that they have neither the vocal anatomy to speak, or hands to allow signing. So at least for now, Chaser is limited to recognizing names of objects and responding to requests or commands. I don't know of any experiments where dogs can be taught to "speak" by, for example, selecting words by touching symbols on a touch screen. It could be done. But has it been done? I don't know.
