Researchers made headlines recently when they changed the color of everyday metals by scouring their surfaces with precise, high-intensity laser bursts. A recent discovery has shown that beyond the aesthetic opportunities in the finding lie some very powerful potential uses, such as diagnosing some diseases with unprecedented ease and precision.
Rats passively exposed to tobacco smoke become dependent on nicotine, according to a new study. The findings of how rats’ brains respond to exposure to tobacco smoke have implications for the study of the effects of tobacco smoke on the human brain and for future studies testing new treatments for tobacco addiction.
Astronomers have taken the deepest image yet of the Universe in near-infrared light. The faintest and reddest objects in the image are likely the oldest galaxies ever identified, having formed between only 600-900 million years after the Big Bang.
While it is too early for physicians to start advising their male patients to take up the habit of regular coffee drinking, new data revealed a strong inverse association between coffee consumption and the risk of lethal and advanced prostate cancers.

Even the snow on Aconcagua Mountain in the Andes is polluted with PCBs. Scientists detected low concentrations of these toxic, carcinogenic chlorine compounds in samples taken from America’s highest mountain. The snow samples taken at an altitude of 6200 meters are among the highest traces found anywhere in the world of these substances, which have [...]

A massive, data-crunching computer search program that matches fragments of potential drug molecules to the known shapes of viral surface proteins has identified several FDA-approved drugs that could be the basis for new medicines — if emerging viruses such as the H5N1 (avian flu) or H1N1/09 (swine flu) develop resistance to current antiviral therapies.
Scientists looking to understand the genetic mechanisms of plant defense and growth have found for the first time in plants an inverse relationship between gene duplication and alternative splicing. The finding has implications for diversity not only in plants, but in animals and humans.
Young adults with higher blood lead levels appear more likely to have major depression and panic disorders, even if they have exposure to lead levels generally considered safe, according to a report in the December issue of Archives of General Psychiatry, one of the JAMA/Archives journals.
