Vast gene-expression map yields neurological, environmental stress insights

A consortium led by scientists from the U.S. Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) has conducted the largest survey yet of how information encoded in an animal genome is processed in different organs, stages of development, and environmental conditions. Their findings paint a new picture of how genes function in the nervous…

White House Launches New Climate Data Website

The White House launched a new effort Wednesday (March 19) to make climate data more accessible to the public. Known as the Climate Data Initiative, the endeavor will bring together on one website all federal climate data, such as flood maps, hurricane tracks and predictions of future sea level rise. The goal is to centralize…

Burmese Pythons Slither Home from Miles Away

Most snakes don't boast strong internal navigation systems, but Burmese pythons have evolved unusually accurate internal maps and compasses that guide them home from many miles away, according to a new report. Burmese pythons — one of the largest species of snakes in the world, capable of growing more than 18 feet (5.5 meters) long —…

Fuel Cells Could Provide Clues to Spark of Life

The origins of life remains one of the greatest mysteries of science. But to simulate the primordial past—and the conditions that could have given rise to the spark of life—some scientists are turning to a technology usually associated with the car of the future: fuel cells. Their usefulness lies in their very basic similarity to…

Dinosaur-Killing Asteroid Triggered Lethal Acid Rain

The oceans soured into a deadly sulfuric-acid stew after the huge asteroid impact that wiped out the dinosaurs, a new study suggests. Eighty percent of the planet's species died off at the end of theCretaceous Period 65.5 million years ago, including most marine life in the upper ocean, as well as swimmers and drifters in lakes…

Climate change will reduce crop yields sooner than thought

A study led by the University of Leeds has shown that global warming of only 2°C will be detrimental to crops in temperate and tropical regions, with reduced yields from the 2030s onwards. Professor Andy Challinor, from the School of Earth and Environment at the University of Leeds and lead author of the study, said:…

Dinosaur skull may reveal T. rex’s smaller cousin from the north

A 70 million year old fossil found in the Late Cretaceous sediments of Alaska reveals a new small tyrannosaur, according to a paper published in the open-access journal PLOS ONE on March 12, 2014 by co-authors Anthony Fiorillo and Ronald S. Tykoski from Perot Museum of Nature and Science, Texas, and colleagues. Tyrannosaurs, the lineage of carnivorous…

Odd Cause of Humans’ Dark Skin Proposed

Skin cancer could have directly driven the evolution of dark skin in humans, a study on people with albinism in modern Africa suggests. Albinism is an inherited disorder that prevents people from making melanin, a black or brown pigment. Albino people in sub-Saharan Africa almost universally die of skin cancer — and at young ages, according to a…

New fossil species: Origin of toothed whale echolocation

Research led by an anatomy professor at New York Institute of Technology College of Osteopathic Medicine indicates that echolocation -- the sonar-like system based on high-frequency vocalizations and their echoes -- was present in a 28-million-year old relative of modern-day toothed whales, dolphins, and porpoises. Associate Professor Jonathan Geisler led the study of a new…

Using Laser Fingerprinting To Identify Salmonella

Bacteria from the genus Salmonella are a major cause of food poisoning. About 40,000 cases of salmonella food poisoning are reported in the United States every year, but according to the Centers for Disease Control and Prevention, about one million people are actually infected with the bacterium every year. Researchers have now developed a new, more rapid…
