Smithsonian researchers report that the brains of tiny spiders are so large that they fill their body cavities and overflow into their legs. As part of ongoing research to understand how miniaturization affects brain size and behavior, researchers measured the central nervous systems of nine species of spiders, from rainforest giants to spiders smaller than the head of a pin. As the spiders get smaller, their brains get proportionally bigger, filling up more and more of their body cavities.

“The smaller the animal, the more it has to invest in its brain, which means even very tiny spiders are able to weave a web and perform other fairly complex behaviors,” said William Wcislo, staff scientist at the Smithsonian Tropical Research Institute in Panama. “We discovered that the central nervous systems of the smallest spiders fill up almost 80 percent of their total body cavity, including about 25 percent of their legs.” (more…)

ARMONK, N.Y. – 09 Jan 2012: IBM today announced it has completed the acquisition of Platform Computing, a privately held company headquartered in Toronto, Ontario, Canada. Financial terms were not disclosed.

On October 11, 2011, IBM announced that it had entered into a definitive agreement to acquire Platform Computing, a global leader in cluster, grid and cloud management software for distributed computing environments. (more…)

Satellite Tracking Helps Russian Tanker Navigate Critical Sea Duck Habitat

ANCHORAGE — On its way to deliver emergency fuel to Nome, Alaska, the Russian tanker Renda will move through an area used by wintering spectacled eiders, a federally threatened sea duck. But, to protect the ducks and their wintering habitat, resource managers from the U.S. Fish and Wildlife Service and navigators from the U.S. Coast Guard are using satellite telemetry information from the U.S. Geological Survey to plot a route for the tanker that minimizes impacts to this species and its habitat.

“Nearly 20 years ago, USGS biologists used the latest satellite tracking technology available at the time to uncover the mysterious wintering behavior of the spectacled eider, now a threatened species,” said USGS Director Marcia McNutt. “Little did these scientists know at the time that their information would be critical in allowing a Russian tanker decades later to thread the needle to Nome in order to deliver life-saving fuel oil without taking a toll on these elusive sea ducks.” (more…)

For Ali Belkacem of Berkeley Lab’s Chemical Sciences Division, “What is chemistry?” is not a rhetorical question.

“Chemistry is inherently dynamical,” he answers. “That means, to make inroads in understanding – and ultimately control – we have to understand how atoms combine to form molecules; how electrons and nuclei couple; how molecules interact, react, and transform; how electrical charges flow; and how different forms of energy move within a molecule or across molecular boundaries.” The list ends with a final and most important question: “How do all these things behave in a correlated way, ‘dynamically’ in time and space, both at the electron and atomic levels?” (more…)

Use of Out-of-Network Services May Explain Higher Health Care Costs For Women

Women generally have been paying higher health care costs than men for many years, and this trend appears to be continuing or worsening since the major economic downturn began in 2008, according to Susan Busch, associate professor of health policy in the Yale School of Public Health.

Busch believes women’s use of out-of-network services might explain, at least in part, this discrepancy. (more…)

50-Million-Year-Old Cricket and Katydid Fossils From Colorado Hint at Origin of Insect Hearing

*The team scoured more than 500 museum drawers of Green River fossils for crickets and katydids with intact front legs, looking for evidence of ears.*

How did insects get their hearing? A new study of 50-million-year-old cricket and katydid fossils sporting some of the best preserved fossil insect ears described to date are helping to trace the evolution of the insect ear.

According to paleontologist Dena Smith of the University of Colorado Boulder’s Museum of Natural History and University of Illinois Professor Roy Plotnick, who collaborated on the new study at the National Evolutionary Synthesis Center, or NESCent, in Durham, N.C., insects hear with help from some very unusual ears.

EAST LANSING, Mich. — New guidelines from the American Academy of Neurology will help physicians better choose seizure drugs for people on HIV/AIDS medication, avoiding deadly drug interactions and preventing critical anti-HIV drugs from becoming less effective, possibly leading to a more virulent strain of the disease.

Michigan State University’s Gretchen Birbeck – who spends several months each year in the sub-Sahara African nation of Zambia researching epilepsy, HIV /AIDS and cerebral malaria – is the lead author of the medical guideline, which was co-developed with the World Health Organization through the International League Against Epilepsy.
