Scientists have identified a genomic "signature" in circulating blood that reveals exposure to common upper respiratory viruses, like the cold or flu, even before symptoms appear. 
Probiotics Help Gastric-bypass Patients Lose Weight More Quickly

Alcohol's inebriating effects are familiar to everyone. But the molecular details of alcohol's impact on brain activity remain a mystery. A new study by researchers at the Salk Institute for Biological Studies brings us closer to understanding how alcohol alters the way brain cells work.
New Design Strategy For Brain Implants Paves The Way To Multi-electrode Deep-brain Stimulation
sea-maid submitted, created time 1 year 4 months (www.sciencedaily.com)
At this week’s Design, Automation & Test in Europe (DATE) conference, IMEC presents a new design strategy for brain implants, which it used to create a prototype multi-electrode stimulation & recording probe for deep-brain stimulation. With this development, IMEC highlights the opportunities in the healthcare market for design tool developers.

A Purdue University study shows dairy has an advantage over calcium carbonate in promoting bone growth and strength.
Peptides-on-demand: McGill researcher's radical new green chemistry makes the impossible possible

McGill University chemistry professor Chao-Jun (C.J.) Li is known as one of the world leading pioneers in green chemistry, an entirely new approach to the science which eschews the use of toxic, petrochemical-based solvents in favor of basic substances like water and new ways of making molecules.
The environmental benefits of the green approach are obvious and significant, but following the road less traveled is also paying off in purely scientific terms
Researchers disrupt biochemical system involved in cancer and other diseases

Screening a chemical library of 200,000 compounds, researchers at UT Southwestern Medical Center have identified two new classes that can be used to study and possibly manipulate a cellular pathway involved in many types of cancer and degenerative diseases.
“The identification of these chemicals and their targets within this cellular pathway represents an important step in developing therapeutic agents,” said Dr. Lawrence Lum, assistant professor of cell biology and senior author of the study, available at Nature Chemical Biology
Food Can Affect a Cell in the Same Way Hormones Do
piggy submitted, created time 1 year 9 months (www.eurekalert.org)
VIB researchers connected to the Katholieke Universiteit Leuven have discovered an important new mechanism with which cells can detect nutrients. This happens in the same way--and with the same effects--as when cells receive a message from a hormone. This finding can teach us more about how food affects our body. Furthermore, it can form the basis for new candidate targets for medicines.
Receptors
Every living thing is composed of cells and, via receptor proteins on their outer surface, cells communicate with each other and with the outside world
Molecular Motor Tied to Memory

How does the brain record a memory? Somehow our experiences and interactions can be imprinted in the mind, but exactly how neurons alter their connections to enable memory has been murky. Now a team of researchers out of Duke University say they have identified the molecular machinery that links experience with learning--and it all comes down to one microscopic motor.

Protein Kinase CK2: new perspectives of an old kinase
Design of specific small molecules that are able to block (inhibit) function of macromolecular targets responsible for the development of certain disorder is the “classic” and most widely used approach in modern drug therapeutics, e.g., in cancer treatment
Walnut trees emit aspirin-like chemical to deal with stress
sea-maid submitted, created time 1 year 11 months (esciencenews.com)
Scientists have known for some time that plants can produce their own stress-killers--aspirin is famously produced in willow and walnut trees--but now they've been able to confirm that these compounds are released into the surrounding atmosphere in significant quantities.

OTAVA Ltd. offers MORE THAN 200 NEW FOCUSED COMPOUND LIBRARIES FOR SCREENING.
They include target-specific compound libraries, e.g, P38 kinase inhibitors, cathepsin B inhibitors, HCV serine protease inhibitors and many others as well as libraries with general pharmacological activities, e.g, antiallergic, antiviral, analgesic and other activities. The focused libraries were designed especially for research and development of new lead compounds.
Experimental chemotherapy regimen shows promise in treating advanced lung cancer
sea-maid submitted, created time 2 years 4 weeks (www.eurekalert.org)
A combination of chemotherapy agents that have been tested in other tumor types appears to be a promising alternative to standard treatment for advanced nonsmall cell lung cancer, according to a report in the Aug. 15 issue of Clinical Cancer Research, a journal of the American Association for Cancer Research.
Happy thoughts may dampen cravings

Want to quit smoking? Next time the urge to light up strikes, think of snow-capped peaks instead of the fleeting pleasure of a white cigarette. That's the conclusion of a new brain study which shows that thinking happy thoughts could help dampen cravings.
Mauricio Delgado, a cognitive neuroscientist at Rutgers University in Newark, New Jersey, and his colleague Elizabeth Phelps of New York University measured the brain activity of 15 volunteers as they played a simple game.
The researchers told their subjects to associate blue cards with a real $4 payoff, and yellow cards with nothing
A natural therapeutic agent for breast cancer
