Researchers from the University of York reported in Science online today that they have created the first genetic map for the medicinal herb Artemisia annua, which contains an extract called artemisinin that's used to help treat some forms of malaria.
Through deep sequencing of a hybrid plant... Read More
A year ago, Michael Taylor was sitting in his office at George Washington University, considering a basic mission of the federal government: making sure food is safe. He'd devoted his career to food safety, working in and out of government, and he was finally in academia where he could think dee... Read More

U.S. Department of Energy Secretary Steven Chu today announced the investment of nearly $80 million under the American Recovery and Reinvestment Act for advanced biofuels research and fueling infrastructure that will help support the development of a clean sustainable transportation sector. The ... Read More
Biological warfare and bioterrorism are as old as fourth-century BCE Scythian fighters wiping their arrows on decomposing bodies before shooting them at their enemies and as new as ricin toxin delivered to a US Senate mailroom in 2004. They consist of using viruses, bacteria, fungi and other tox... Read More
It is known that viral "squatters" comprise nearly half of our genetic code. These genomic invaders inserted their DNA into our own millions of years ago when they infected our ancestors. But just how we keep them quiet and prevent them from attack was more of a mystery until EPFL researchers re... Read More
One California pet frog breeder may be the source of a nationwide salmonella poisoning outbreak that has lasted for eight months.
Cases of salmonella that have sickened people throughout the United States have been liked to African dwarf frogs from one breeder. The pet frogs were subsequently... Read More
Bacteria such as methicillin-resistant staphylococcus aureus (MRSA) are a growing problem in hospitals and researchers are anxious to understand how they evolve.
Norwegian researchers said they had found little sign of such microbes in the feces of polar bears in the remote Arctic, suggesting... Read More
Nestlé USA said Wednesday that two samples of its Toll House refrigerated cookie dough made at a Virginia factory tested positive for E. coli bacteria this week despite rigorous safety measures put in place after a recall of the product last summer.
Nestlé also said the tainted dough had not ... Read More
The chromosomal DNA of several mammals has been found to contain sequences related to the nucleoprotein (N) gene of bornaviruses, enveloped viruses with a negative-strand RNA genome. I am amazed by this finding. How did bornaviral DNA get in our chromosomes, and what is it doing there? Read More
Soybean, one of the most important global sources of protein and oil, is now the first legume species with a published complete draft genome sequence. The sequence and its analysis appear in the January 14 edition of the journal Nature. The research team comprised 18 institutions, including th... Read More
Salmonella bacteria on lettuce penetrate the leaves to enter inner tissues via stomata, while also actively swimming toward photosynthetically produced nutrients, according to Shlomo Sela and other members of an Israeli research team.
Although other bacterial plant pathogens also enter plant ... Read More
And so the backlash begins. As the current wave of H1N1 flu starts to fade in Europe, questions are being asked about the expensive vaccines bought to fight it.
Later this month members of parliament from countries in the Council of Europe, a club of 47 countries, will hold an inquiry into wh... Read More
Science research councils have increasingly encouraged their grant-holders to engage with the public about their work and for many research grants some form of public engagement is now a necessity. But whom do these scientists end up engaging?
With the advent of online content, where people c... Read More
Final proof that Mars has bred life will be confirmed this year, leading NASA experts believe. The historic discovery will come not on Mars itself but from chunks of the red planet here on Earth.
David McKay, chief of astrobiology at NASA's Johnson Space Centre in Houston, says powerful new m... Read More
A European Commission consortium said today that it plans to pump as much as €8.5 million ($12.4 million) over the next three years into its international effort to fund genomic studies of human pathogens and to develop ways to combat them.
In its third funding call, the ERA-NET PathoGenoMics... Read More
Researchers at the University of Michigan's Life Sciences Institute have developed a new method to rapidly generate and test novel antibiotic-drug candidates. The technique could provide scientists with a new tool in the fight against antibiotic-resistant bacteria.
LSI research assistant prof... Read More
Every time one problem gets solved, it seems another crops up. This is the case with the childhood pneumonia vaccine.
Since the vaccine was introduced almost a decade ago to stamp out bacterial pneumonia, there has been a big drop in that serious lung disease. But there has also been a dramat... Read More
Genetic analyses of avian influenza in wild birds can help pinpoint likely carrier species and geographic hot spots where Eurasian viruses would be most likely to enter North America, according to new U.S. Geological Survey research.
Persistence of the highly pathogenic avian influenza H5N1 (... Read More
Google just launched an updated version of Google Flu Trends, a service that predicts flu trends by tracking flu related queries on the company's search engine. Until now, Google only showed aggregate data for states in the United States. Starting today, Flu Trends will show data down to the cit... Read More
