Washington University in St. Louis A brain chemical that desynchronizes the cells in the biological clock helps the clock adjust more quickly to abrupt shifts in daily light/dark schedules such as those that plague modern life A small molecule called VIP, known to synchronize time-keeping neurons in the brain's biological clock, has the startling effect of desynchronizing them at higher dosages, says a research team at Washington University in St. Louis. Far from being catastrophic,...

Veil Of Ignorance Is Sometimes Bliss
2013-10-24 08:22:27

Washington University in St. Louis A range of examples suggests a lack of information about their fellows can favor cooperation and prevent conflict among animals — and even among genes For the Oct. 16 issue of Biology Letters, a special issue commemorating the 50th anniversary of W.D. Hamilton’s famous paper on kin selection, two Washington University in St. Louis biologists contributed an article describing intriguing exceptions to one of his predictions. The basic idea of...

Model Organisms Gone Wild

Washington University in St. Louis Amoebas that are placid, model organisms in the lab, farm bacteria and carry guards to protect their crops in the wild Model organisms, brought into labs because they are easy to work with, adapt to the lab, often shedding characteristics that allowed them to survive in the wild. Scientists who work with model organisms rarely look at the wild strains, but when they do, they can be surprised by what they find. This is what happened with the...

Lab-made Complexes Absorb More Sunlight

Washington University in St. Louis A ring of protein and pigments, half synthetic and half natural, can be used to quickly prototype light-harvesting antennas that absorb more sunlight than fully natural ones In diagrams it looks like a confection of self-curling ribbon with bits of bling hung off the ribbon here and there. In fact it is a carefully designed ring of proteins with attached pigments that self-assembles into a structure that soaks up sunlight. The scientists who made it...

Flexible Hub Network Of The Brain Helps Humans Adapt

Washington University in St. Louis Switching stations route processing of novel cognitive tasks One thing that sets humans apart from other animals is our ability to intelligently and rapidly adapt to a wide variety of new challenges — using skills learned in much different contexts to inform and guide the handling of any new task at hand. Now, research from Washington University in St. Louis offers new and compelling evidence that a well-connected core brain network based in the...

Tiny Single-celled Organisms Have Amazingly Complicated Social Lives
2013-07-30 09:06:00

Washington University in St. Louis In 2011, Nature announced that scientists had discovered a single-celled organism that is a primitive farmer. The organism, a social amoeba called Dictyostelium discoideum, picks up edible bacteria, carries them to new locations and harvests them like crops. D. discoideum enjoyed a brief spell in the media spotlight, billed as the world's smallest farmer. Now a collaboration of scientists at Washington University in St. Louis and Harvard University...
