For mice, carbon dioxide often means danger — too many animals breathing in too small a space or a hungry predator exhaling nearby. Mice have a way of detecting carbon dioxide, and new research from…

Astronomers have discovered a chaotic scene unlike any witnessed before in a cosmic “train wreck” between giant galaxy clusters. NASA’s Chandra X-ray Observatory and optical telescopes revealed a…

Scientists have determined for the first time the atomic structure of an ancient protein, revealing in unprecedented detail how genes evolved their functions. "Never before have we seen so clearly,…

Wastewater treatment plants are designed primarily to eliminate nutrients. However, attention is increasingly being focused on micropollutants, since even low concentrations of these substances can…

Pressures and temperatures at the Earth’s core are stupendous – more than 3.5 Mbar and 7000K – and currently it is impossible to recreate these conditions in the laboratory. Our information about…

Prof. Yadin Dudai, Head of the Weizmann Institute’s Neurobiology Department, and his colleagues recently discovered that the process of storing long-term memories is much more dynamic than previously…

Most modern attempts to decipher how portions of genetic code are translated into physical characteristics are akin to a first-grader trying to sound out a word letter by letter — or, in this case,…

Kaiping Peng, a friend of mine who is a professor at Berkeley, recently said to me that professors have an unusual place in our society: They are expected to tell the truth. Hardly anyone else is, he…

Natural selection has driven two closely related species of fish in Lake Malawi down different evolutionary paths - even though they live side by side. An international team of scientists from Canada…

A team of researchers investigating cholesterol and lipid transport has performed experiments that cast serious doubt on the dominant hypothesis of how the body rids its cells of "bad" cholesterol…

Most people understand how liquids freeze as solid crystals when temperatures become cold enough, like water droplets crystallizing into snowflakes or molten glass hardening into solid glass. Latter…

Scientists have discovered a new protein that may offer fresh insights into brain function in mad cow disease. “Our team has defined a second prion protein called ‘Shadoo’, that exists in addition to…

All bad jokes aside, their research represents a step forward in computers reaching the capability of a human mind. "This work has a relationship to 'Sociable Computing,'" says Larry Mazlack.…

Brain imaging has revealed a breakdown in normal patterns of emotional processing that impairs the ability of people with clinical depression to suppress negative emotional states. Efforts by…

Individuals with chronic myeloid leukemia (CML) are treated first with a drug known as imatinib (Gleevec), which targets the protein known to cause the cancer (BCR-ABL). If their disease returns,…

An unusual investigation was recently carried out by researchers under the guidance of Tatiana Rebeko, Ph.D. at the Institute of Psychology, Russian Academy of Sciences. Their interest was beauty…

Research from The University of Nottingham sheds new light on a fascinating phenomenon of the natural world — the ability of some species to reproduce sexually without a partner. Scientists have been…

In their search for the cellular and molecular causes of multiple sclerosis, an Italian-German research team has identified a subgroup of protective immune cells (suppressor cells) which are…

By using pulses of light to dramatically accelerate quantum computers, University of Michigan researchers have made strides in technology that could foil national and personal security threats. It's…

With all the talk of contaminated food pouring in from China and elsewhere, I have to wonder how safe our food supply really is. Let’s face it! It’s not just food coming from outside our borders that…
