Researchers reveal how hearing evolved

Posted: 06 Feb 2015 09:52 AM PST

Lungfish and salamanders can hear, despite not having an outer ear or tympanic middle ear. These early terrestrial vertebrates were probably also able to hear 300 million years ago, as shown in a new study.

Another reason to drink wine: It could help you burn fat, study suggests

Posted: 06 Feb 2015 08:17 AM PST

Drinking red grape juice or wine -- in moderation -- could improve the health of overweight people by helping them burn fat better, a new study indicates. The findings suggest that consuming dark-colored grapes, whether eating them or drinking juice or wine, might help people better manage obesity and related metabolic disorders such as fatty liver.

Settling for 'Mr. Right Now' better than waiting for 'Mr. Right', shows model of digital organisms

Posted: 06 Feb 2015 08:16 AM PST

Evolutionary researchers have determined that settling for 'Mr. Okay' is a better evolutionary strategy than waiting for 'Mr. Perfect.' When studying the evolution of risk aversion using a computational model of digital organisms, researchers found that it is in our nature -- traced back to the earliest humans -- to take the safe bet when stakes are high, such as whether or not we will mate.

Researchers have discovered a way to map 'reed die-back' using satellites and aircraft.

Ancient snow patches melting at record speed

Posted: 06 Feb 2015 04:12 AM PST

Norway is dotted with small glaciers and permanent snow patches that contain all sorts of archaeological treasures, from ancient shoes to 5000-year-old arrowheads. But climate change has turned up the temperature on these snowfields and they are vanishing at an astonishing rate.

Cow immune system inspires potential new therapies

To help people with hormone deficiencies, scientists have developed a potential new therapy based on an unlikely model: immune molecules from cows.

When scientists play with Lego: A new creative version of pinned insect manipulator

Posted: 05 Feb 2015 09:31 AM PST

Who said scientists are not creative? Biologists have proved such statements wrong with the invention of a creative, functional and most importantly quite cheap pinned insect manipulator made entirely of Lego pieces to help them face the challenges of mass digitization of museum specimens.

Survival of the fittest: Evolution continues despite low mortality and fertility rates in modern world

Posted: 05 Feb 2015 09:30 AM PST

Charles Darwin's theory on evolution still holds true despite lower mortality and fertility rates in the modern world, according to new research.

Closer look at flawed studies behind policies used to promote 'low-carbon' biofuels

Posted: 05 Feb 2015 09:27 AM PST

Nearly all of the studies used to promote biofuels as climate-friendly alternatives to petroleum fuels are flawed and need to be redone, according to a researcher who reviewed more than 100 papers published over more than two decades.

New finding may compromise aging studies

Posted: 04 Feb 2015 11:46 AM PST

Scientists found that a hormone they were using to selectively activate genes in flies for life span studies was actually extending the lives of mated female flies by 68 percent.
