Latest and Breaking Biology News

ESA Frontiers November preview
(Ecological Society of America) Connectivity cost calculations for conservation corridors, crop companions, jellyfish and human well-being and micromanaging microbes.

Researchers probe link between newborn health and vitamin A
(Penn State) The impact vitamin A has on newborns is virtually unknown, but Penn State nutrition researchers have published two papers that may provide a framework for future investigations of the vitamin and neonatal health.

Link seen between seizures and migraines in the brain
(Penn State) Seizures and migraines have always been considered separate physiological events in the brain, but now a team of engineers and neuroscientists looking at the brain from a physics viewpoint discovered a link between these and related phenomena.

2014 Antarctic ozone hole holds steady
(NASA/Goddard Space Flight Center) The Antarctic ozone hole reached its annual peak size on Sept. 11, according to scientists from NASA and the National Oceanic and Atmospheric Administration. The size of this year's hole was 24.1 million square kilometers (9.3 million square miles) -- an area roughly the size of North America.

Himalayan Viagra fuels caterpillar fungus gold rush
(Washington University in St. Louis) Overwhelmed by speculators trying to cash-in on a prized medicinal fungus known as Himalayan Viagra, two isolated Tibetan communities have managed to do at the local level what world leaders often fail to do on a global scale -- implement a successful system for the sustainable harvest of a precious natural resource, suggests new research from Washington University in St. Louis.

Celebrating the work of the 2014 Nobel Laureates
(Wiley) John Wiley & Sons, Inc., would like to congratulate all of the 2014 Nobel laureates and is proud to have published work by nine of the laureates. To celebrate their achievements Wiley has made a selection of content from the 2014 winners free to access until the end of the year.

New optimal screening threshold for gestational diabetes in twin pregnancies
(Elsevier Health Sciences) Gestational diabetes affects approximately 6-7 percent of pregnant women. Currently, screening is done in two steps to help identify patients most at risk; however, the suggested levels for additional testing were based on singleton pregnancy data. Now investigators have analyzed data from twin pregnancies and have determined that the optimal first step cutoff for additional screening appears to be a blood sugar level equal to or greater than 135 mg/dL for women carrying twins.

They know the drill: UW leads the league in boring through ice sheets
(University of Wisconsin-Madison) Hollow coring drills designed and managed by UW-Madison's Ice Drilling Design and Operations program are used to extract ice cores that can analyze the past atmosphere. Shaun Marcott, an assistant professor of geoscience at UW-Madison, was the first author of a paper published today in the journal Nature documenting carbon dioxide in the atmosphere between 23,000 and 9,000 years ago, based on data from an 11,000-foot hole in Antarctica.

Study shows vibrating insoles could reduce falls among seniors
(Peters Communications) Findings published in the Archives of Physical Medicine and Rehabilitation show that imperceptible vibratory stimulation applied to the soles of the feet improved balance by reducing postural sway and gait variability in elderly study participants. The vibratory stimulation is delivered by a urethane foam insole with embedded piezoelectric actuators, which generates the mechanical stimulation.

Biology meets geometry
(University of California - Santa Barbara) Architecture imitates life, at least when it comes to those spiral ramps in multistory parking garages. Stacked and connecting parallel levels, the ramps are replications of helical structures found in a ubiquitous membrane structure in the cells of the body.
