Researchers: Molecular forklifts overcome obstacle to 'smart dust'
Algae is a livid green giveaway of nutrient pollution in a lake. Scientists would love to reproduce that action in tiny particles that would turn different colors if exposed to biological weapons, food spoilage or signs of poor health in the blood. view more (2009-01-20)
Rethinking the genetic theory of inheritance
Scientists at the Centre for Addiction and Mental Health (CAMH) have detected evidence that DNA may not be the only carrier of heritable information; a secondary molecular mechanism called epigenetics may also account for some inherited traits and diseases. view more (2009-01-20)
A new mechanism regulates type I interferon production in white blood cells
A study from a team of researchers led by Dr. Andrew P. Makrigiannis, Director of the Molecular Immunology Research Unit at the IRCM, has identified a new mechanism regulating interferon production. view more (2009-01-13)
Iowa State University researchers discover structure of key Ebola protein
Research led by Iowa State University scientists has them a step closer to finding a way to counter the Ebola virus. view more (2009-01-13)
Digital Communication Technology Helps Clear Path to Personalized Therapies
Researchers at the Burnham Institute for Medical Research (Burnham) have shown that search algorithms used in digital communications can help scientists identify effective multi-drug combinations. view more (2009-01-12)
Biologists discover link between CGG repeats in DNA and neurological disorders
Researchers have long known that some repetitive DNA sequences can make human chromosomes "fragile," i.e. appearing constricted or even broken during cell divisions. view more (2009-01-12)
Lost in translation
The enzyme machine that translates a cell's DNA code into the proteins of life is nothing if not an editorial perfectionist. view more (2009-01-08)
Team finds breast cancer gene linked to disease spread
A team of researchers at Princeton University and The Cancer Institute of New Jersey has identified a long-sought gene that is fatefully switched on in 30 to 40 percent of all breast cancer patients, spreading the disease, resisting traditional chemotherapies and eventually leading to death. view more (2009-01-06)
Cell Biologists Identify New Tumor Suppressor for Lung Cancer
Cancer and cell biology experts at the University of Cincinnati (UC) have identified a new tumor suppressor that may help scientists develop more targeted drug therapies to combat lung cancer. view more (2009-01-06)
Apolipoprotein(a): A natural regulator of inflammation
In a study to be published in the January 09 issue of Experimental Biology and Medicine, Hoover-Plow and co-workers in seeking to define a role of apo(a) in leukocyte recruitment have identified a novel activity of apo(a) apolipoprotein that may function as a natural and cell specific suppressor of the inflammatory response in vivo. view more (2008-12-29)
Pitt, NETL researchers report molecular chain reaction thought to be impossible
People said it couldn't be done, but researchers from the University of Pittsburgh and the U.S. Department of Energy National Energy Technology Laboratory (NETL) in Pittsburgh demonstrated a molecular chain reaction on a metal surface, a nanoscale process with sizable potential in areas from nanotechnology to developing information storage... view more...

Properties of Unusual Virus Revealed in Researchers
A team of researchers from Penn State University and the University of Chicago has uncovered clues that may explain how and why a particular virus, called N4, injects an unusual substance -- an RNA polymerase protein -- into an E. coli bacterial cell. The results, which are published in the current issue of the journal Molecular Cell, contribute... view more... (2008-12-09)
'Zinc Zipper' Plays Key Role In Hospital-Acquired Infections
Hospital-acquired infections that are resistant to traditional antibiotic treatment have become increasingly common in recent years, confounding health care professionals and killing thousands of Americans. view more (2008-12-05)
Scripps Research Scientists Shed Light on How DNA Is Unwound So That Its Code Can Be Read
Researchers at The Scripps Research Institute have figured out how a macromolecular machine is able to unwind the long and twisted tangles of DNA within a cell's nucleus so that genetic information can be "read" and used to direct the synthesis of proteins, which have many specific functions in the body. view more (2008-11-25)
Systems biology brings hope of speeding up drug development
Almost every day brings news of an apparent breakthrough against cancer, infectious diseases, or metabolic conditions like diabetes, but these rarely translate into effective therapies or drugs, and even if they do clinical development usually takes well over a decade. view more (2008-11-20)
Worker ants of the world, unite! You have nothing to lose but your fertility
The highly specialized worker castes in ants represent the pinnacle of social organization in the insect world. As in any society, however, ant colonies are filled with internal strife and conflict. So what binds them together? More than 150 years ago, Charles Darwin had an idea and now he's been proven right. view more (2008-11-20)
Leeds researchers reshape the future of drug discovery
Scientists in Leeds have devised a new way to create the next generation of man-made molecules in a breakthrough that could revolutionise drug development. view more (2008-11-19)
Benign or cancerous?
Research into a cancer that is on the rise in the UK is to be presented at the University of Leicester. view more (2008-11-12)
What makes an axon an axon?
Inside every axon is a dendrite waiting to get out. Hedstrom et al. converted mature axons into dendrites by banishing a protein crucial for neuron development. view more (2008-11-10)
New journal shows half-broken gene is enough to cause cancer
Tumour suppressor genes do not necessarily require both alleles to be knocked out before disease phenotypes are expressed. Research published in BioMed Central's new open access journal PathoGenetics reveals that only one allele of SMAD4 has to be damaged to put a person at risk of pancreatic and colorectal cancer. view more (2008-11-04)
