From the Cover: Major evolutionary transitions in ant agriculture
All attine ants obligately depend on the cultivation of fungus gardens for food. So complete is this dependence that, upon leaving the maternal nest, a daughter queen must carry within her mouth a nucleus of fungus that serves as the starting culture for her new garden

Shawn Brixey - Wikipedia
In Brixey's project Alchymeia, designed for the 1998 Winter Olympics in Nagano, Japan, the naturally occurring steroids from the blood and urine of Olympic athletes were used as doping agents to stimulate the growth of unusual snowflakes that would otherwise be impossible to find in nature.[8]

Your drain on drugs: Meth seeps into Baltimore's streams -
Here's why: These plants and bugs are the base of the aquatic food web. Birds eat the bugs, as do frogs and fish. As emergent contaminants such as pharmaceuticals and endocrine disruptors become more common in ground and drinking water, they could affect humans. Scientists say the direct health effects are pretty much unknown, and more research will need to be done.

BioBIKE Portal
One solution is for biologists to become familiar with a few tools, such as Blast. This gets the researcher from one point to another, like flying high above the terrain. Some places are impossible to get to in this way.

Another solution is to procure the services of a computer programmer. This may produce new tools appropriate to the problem at hand, but it is like traveling in a darkened limosine, where the passenger directs the driver but with no first hand knowledge of the surrounding world.

BioBIKE offers a different solution, one where a computationally inexperienced researcher may ride leisurely through the data, observing its novelty and responding directly to it.

“Sharks create oxygen”: A scientific perspective | Southern Fried Science
"The premise of the sharks and oxygen claim is as follows: A) Sharks, many of which are apex predators, are important in regulating marine food webs; B) Phytoplankton, which create oxygen through photosynthesis, are in marine food webs; C) Therefore, without sharks, phytoplankton populations will crash and we won’t have any more oxygen and we’ll all die.

Pyura chilensis: the closest thing to getting blood from a stone | Running Ponies, Scientific American Blog Network
Their blood is clear and, strangely, can accumulte extremely high qualities of a mysterious and rare element called vanadium. The concentration of vanadium in the blood of P. chilensis and other tunicates can be up to 10 million times that of the surrounding seawater. Just why and how these creatures are able to accumulate vanadium in such huge quantities remains unknown.

Mysterious hog farm explosions stump scientists
A strange new growth has emerged from the manure pits of midwestern hog farms. The results are literally explosive.

Since 2009, six farms have blown up after methane trapped in an unidentified, pit-topping foam caught a spark. In the afflicted region, the foam is found in roughly 1 in 4 hog farms.

The Mystery of the Canadian Whiskey Fungus | Magazine
Even weirder, how does a fungus that’s millions of years old, older than Homo sapiens, find a near-perfect ecological niche amid stuff people have been making for only a couple of centuries? Presumably somewhere in the world, naturally occurring Baudoinia lives adjacent to naturally fermenting fruit—or maybe it’s everywhere, a sluggish loser until it gets a whiff of ethanol. Evolution is full of stories of animals and plants fitting into hyper-specific man-made niches, as if nature somehow got the specs in advance. “It’s an urban extremophile,”

Information Processing in Human Body
The total information processing activity of the brain is hard to estimate because the current knowledge in this area is fragmentary. However, it is possible to get a general picture of the electronic pulse exchange activity within a couple of orders of magnitude. The activity of the brain is equivalent to that of 1000 kHz processor with 40 Gbits of states. The corresponding processing power (channel capacity) is C=4*1013 bit/s. The minimum necessary power to perform the computations is P=C k T log e, where k is Boltzmann constant and T is the temperature (310 K). So P=1.2*10-7 W. If we assume that brain only needs the energy to perform the computations, the efficiency is about 10-8 of the physical limit.

Inquiry-Based Biology Labs Give Students a Taste of Research | Center for Teaching | Vanderbilt University
David Salisbury, one of the writers for Vanderbilt’s Research News, recently blogged about the inquiry-based biological sciences lab course designed and taught by senior lecturer Steve Baskauf. The course is an alternative to the standard second-semester lab course. It offers students an opportunity to design their own experiments to answer open questions in biology instead of working through the traditional “cookbook” style labs often seen in other science lab courses.
