"In July 1960, Jane Goodall boarded a boat, and after a few hours motoring over the warm, deep waters of Lake Tanganyika, she stepped onto the pebbly beach at Gombe. Last summer, almost exactly 54 years later, Jane Goodall was standing on the same beach. The vast lake was still warm, the beach beneath her clear plastic sandals still pebbly. But nearly everything else in sight was different."
If other horses are the equivalent of feral dogs, then the Przewalski’s horse is a wolf. In its native Mongolia, where it goes by the name takhi, it is known as the father of horses. Mongolians regard the takhi as spiritual, holy animals, and for millennia they largely left them alone... The trouble all began in the late 19th century, when the Western world finally took note of the takhi. Nikolai Przewalski, a Polish-born explorer serving as a colonel in the Russian army, “discovered” the horses during an 1878 expedition to the Mongolian-Chinese frontier. Naturally, Przewalski named the horse after himself, and when he returned to the West, word quickly spread among zoos, adventurers, and curio collectors about the mysterious wild horses.

That's right - it's time for Mammal March Madness! "Battle outcome is a function of the two species' attributes within the battle environment. Attributes considered in calculating battle outcome include temperament, weaponry, armor, body mass, fight style, and other fun facts that are relevant to the outcome. These are one on one- head to head combat situations- um except for the mythical mammals that have multiple heads. Some random error has been introduced into calculating battle outcome & the amount of that error is scaled to the disparity in rankings between combatants. Early rounds, the battle occurs in the better-ranked species' habitat (home court advantage). BUT once we get to the ELITE EIGHT, battle location will be random: forest, semi-arid desert, intertidal zone, or snowy tundra." Action kicks off on March 9 with the wildcard match up between the pygmy jerboa and the bumblebee bat (Kitti's Hognosed Bat).

In this paper, we examine a first-year torque and angular acceleration problem to address a possible use of the forelimbs of Tyrannosaurus rex. A 1/40th-scale model is brought to the classroom to introduce the students to the quandary: given that the forelimbs of T. rex were too short to reach its mouth, what function did the forelimbs serve? This issue crosses several scientific disciplines including paleontology, ecology, and physics, making it a great starting point for thinking “outside the box..." Lipkin and Carpenter have suggested that the forelimbs were used to hold a struggling victim (which had not been dispatched with the first bite) while the final, lethal bite was applied. If that is the case, then the forelimbs must be capable of large angular accelerations α in order to grab the animal attempting to escape. The concepts of the typical first-year physics course are sufficient to test this hypothesis... Naturally, student love solving any problem related to Tyrannosaurus rex.

New GM technique injects mosquitoes with a gene that results in mostly male offspring, eventually leading to a population crash. Previous efforts to tackle the disease, that kills more than 1 million people each year – most of whom are African children – have included bed nets to protect people and insecticides to kill the mosquito species most responsible for the transmission of malaria (Anopheles gambiae). The new technique by a team at Imperial College London involves injecting mosquitoes with a gene that causes the vast majority of their offspring to be male, leading to an eventual dramatic decline in population within six generations as females disappear. “You have a short-term benefit because males don’t bite humans [and transmit malaria],” Andrea Crisanti, one of the authors of the new research, which was published in the journal Nature Communications on Tuesday, told the Guardian. “But in the long term you will eventually eradicate or substantially reduce mosquitoes. This could make a substantial contribution to eradicating malaria, combined with other tools such as insecticides.”
These new mosquitoes are now set to be used in Brazil, having been approved for use by the Brazilian government with a factory for their production now opened.[more inside]

Last November, after five years of remarkable negotiations that unfolded far from the Delta, representatives from the U.S. and Mexico agreed to a complex, multi-part water deal that will give them desperately needed flexibility for weathering the drought. More surprisingly, the two nations will join the team of environmental organizations to release a flood of more than 105,000 acre-feet of water – 3.8 million big-rig tankers' worth – into the Delta's ancient floodplain, and chase it with a smaller, permanent annual flow to sustain the ecosystem.For High Country News, Matt Jenkins describes the most ambitious water sharing plan ever created between Mexico and the United States (single page print version). For much more about this project and the water issues surrounding it, there's Eli Rabett's roundup of John Fleck's blogposts about this. (Or read the tl;dr version by Alex Harrowell.)
It is the unlikeliest of times to pull off a deal like this. Rather than hoarding all the water for themselves in this drought –– the river supplies some 35 million people –– the West's largest water agencies have pledged to send some all the way to the sea. That move is, to some extent, a long-overdue acknowledgment that the U.S. bears responsibility for the impacts its dams have caused beyond its borders. And after years of fruitless court fights in the U.S. by environmental groups, the Mexican government finally insisted that water for the Delta be a cornerstone of the broader deal.
Humans have co-evolved with the resident microbes that call us "home", known as the microbiota, consisting of trillions of cells that colonize our bodies. The microbiota carry out many beneficial functions, such as producing vitamins, aiding in digestion, and protecting against invading microbes, but disruption from antibiotics or delivery by Caesarian section may have consequences for human health. Recently, antibiotic use has been linked with obesity and asthma. Using both human studies and experimentally observed mice, we are beginning to understand how antibiotics may lead to the disappearance of microbes and to identify key microbes that impact our health.[more inside]

Network Theory Overview - "The idea: nature and the world of human technology are full of networks! People like to draw diagrams of networks. Mathematical physicists know that in principle these diagrams can be understood using category theory. But why should physicists have all the fun? This is the century of understanding living systems and adapting to life on a finite planet. Math isn't the main thing we need, but it's got to be part of the solution... so one thing we should do is develop a unified and powerful theory of networks." (via ;)

Scientific American reports: "An isolated population of Arctic foxes that dines only on marine animals seems to be slowly succumbing to mercury poisoning." Though a definitive causal link is difficult to establish, an isolated population of arctic foxes on Russia's Mednyi Island is believed to be collapsing due to mercury contamination as a result of its seafood-heavy diet. Where does all that mercury in the environment come from anyway? Why, it's another biproduct of burning fossil fuels, of course, and predictably, rates of mercury pollution are only expected to increase. In some places in the US, even rainwater is showing high levels of contamination. [more inside]

If you think you can magic us out of the progress trap with new ideas or new technologies, you are wasting your time. If you think that the usual “campaigning” behavior is going to work today where it didn’t work yesterday, you will be wasting your time. If you think the machine can be reformed, tamed, or defanged, you will be wasting your time. If you draw up a great big plan for a better world based on science and rational argument, you will be wasting your time. If you try to live in the past, you will be wasting your time. If you romanticize hunting and gathering or send bombs to computer store owners, you will be wasting your time. And so I ask myself: what, at this moment in history, would not be a waste of my time?

"...by persisting in the false belief that coral reefs have a future, we grossly misallocate the funds needed to cope with the fallout from their collapse." In the New York Times, ecologist Roger Bradbury argues that it's too late to save a big chunk of the Earth's environment, and that we should instead spend our resources getting ready for the challenges we'll face once that part of the world is destroyed. Marine scientists offer varying opinions on how doomed the reefs are, ranging from "Yep, they're doomed" to "If we stopped increasing CO2 concentration in the atmosphere today, they would probably stick around in some more or less degraded form" to "it’s clear to me that corals as a group of living things will almost assuredly* construct glorious reefs in millenniums to come of unimaginable richness."
