Natural killer cells help keep immune system in balanceOctober 2nd, 2009 WASHINGTON - Natural killer (NK) cells, part of our immune system, kill cells infected with a given virus. Researchers have now found that the cells also help keep T-cells from over-responding.
We can build n-plants up to 3,000-4,000 MW: L&TSeptember 29th, 2009 NEW DELHI - Engineering and Construction major Larsen & Toubro Tuesday said it can build nuclear power plants with generating capacity of 3,000-4,000 MW a year. L&T chairman and manging director A.M.
New computing tool may help scientists create tastier and longer lasting tomatoesSeptember 23rd, 2009 WASHINGTON - Scientists have developed a new computing tool that could help scientists predict how plants will react to different environmental conditions in order to create better crops, such as tastier and longer lasting tomatoes. The tool will form part of a new 1.7 million pounds Syngenta University Centre at Imperial College London, which will see researchers from Imperial and Syngenta working together to improve agricultural products.
Natural plant hormone can help plants eliminate pesticide residuesSeptember 10th, 2009 WASHINGTON - Chinese researchers have discovered a natural plant hormone that can help plants eliminate residues of certain pesticides. Researchers have been seeking new ways of minimizing pesticide residues that remain in food crops after harvest - with little success.
Scientists discover key missing link in signaling pathway for plant steroid hormonesSeptember 9th, 2009 WASHINGTON - Researchers at the Carnegie Institution's Department of Plant Biology have discovered a key missing link in the so-called signaling pathway for plant steroid hormones. Many important signaling pathways are relays of molecules that start at the cell surface and cascade to the nucleus to regulate genes.
Key feature of immune system survived in humans for 60 million yearsAugust 19th, 2009 WASHINGTON - A new study has concluded that one key part of the immune system survived in the humans and other primates for almost 60 million years. Researchers at the Oregon State University (OSU) and the Cedars-Sinai Medical Center in the US carried out the study.
New crops needed in case of continued rise in CO2 levelsJune 29th, 2009 WASHINGTON - A new research has determined that new crops would be needed to be grown in the future if carbon dioxide (CO2) levels continue to rise. Global food security in a changing climate depends on the nutritional value and yield of staple food crops.
Two structures from old immune system offer hope for treating diseases, infectionJune 18th, 2009 LONDON - Two new structures, belonging to the oldest branch of the human immune system, have revealed how it fights invading microbes while avoiding problems of the body attacking itself. Both structures involve a central component of an enzyme important to the complement system of the immune response.
Scientists find novel way of boosting newborns' immune responsesJune 13th, 2009 WASHINGTON - Newborns have immature immune system which makes them highly vulnerable to infections. Now, researchers from Children's Hospital Boston claim to have found a novel way to enhance innate immunity that would help keep respiratory syncytial virus, pneumococcus and rotavirus at bay.
Scientists unravel how smallpox virus sabotages our immune systemMay 12th, 2009 WASHINGTON - Researchers are closing in on how smallpox virus go about their deadly business of sabotaging our immune system. These findings may reveal as much about our immune system as they do about one of the world's most feared pathogens.

Why flu may affect some more severely than othersMay 5th, 2009 WASHINGTON - With the swine flu turning into a global pandemic, scientists have now discovered important clues about why influenza is more severe in some people than it is in others. Researchers at the Children's Hospital of Philadelphia, Pennsylvania, have shown that the influenza virus can actually paralyse the immune systems of otherwise healthy individuals, which could lead to severe secondary bacterial infections, such as pneumonia.
Why do seasonal allergies increase in springMay 1st, 2009 WASHINGTON - Spring season is often accompanied by allergies and increased problems for asthmatic people. Now, American scientists have identified a previously unknown cellular switch that turns allergies and asthma both on and off.
Biofuel crops can become invasive pests in tropical areasApril 22nd, 2009 WASHINGTON - In a new research, scientists have concluded that biofuel crops proposed for use in the Hawaiian Islands are two to four times more likely to become invasive pests in Hawaii and other tropical areas when compared to a random sample of other introduced plants. The research was done by scientists with the University of Hawaii Pacific Cooperative Studies Unit, who examined the impact of unregulated planting of biofuel crops for their potential invasiveness and raised concerns about their impacts on Hawaii's environment.
Scientists identify compound that makes plants immune to diseasesApril 4th, 2009 WASHINGTON - Researchers at Oak Ridge National Laboratory (ORNL) and the University of Chicago have identified a novel compound that primes a plant's immune system, which may lead to the development of disease-resistant plants. The team, which includes Tim Tschaplinski of the Department of Energy's ORNL, has determined that azelaic acid has a role in priming the immunity response in Arabidopsis, a small flowering plant related to cabbage and mustard.
