More than two and a half billion years ago, Earth differed greatly from our modern environment, specifically in respect to the composition of gases in the atmosphere and the nature of the life forms inhabiting its surface. While today's atmosphere consists of about 21 percent oxygen, the ancient... Read More
In the aftermath of the explosion of BP's Deepwater Horizon drilling rig in the Gulf of Mexico, a dispersed oil plume was formed at a depth between 3,600 and 4,000 feet and extending some 10 miles out from the wellhead. An intensive study by scientists with the Lawrence Berkeley National Laborat... Read More
Searching for novel viruses in environmental samples is a lot like searching for a needle in a haystack, but harder. Researchers are usually forced to extract genetic material from a sample, then sequence and align those genes against a database of known sequences, but aligning genes is difficu... Read More
Two preclinical studies which evaluated AVI-7100 against a fully virulent pandemic H1N1 (swine flu) virus had promising results, says AVI Biopharma Inc. Data from the studies revealed statistically significant reductions in average viral titer vs. a saline control (placebo) and a Tamiflu control... Read More
Arizona State University researchers have demonstrated a way to simplify testing patients for infectious diseases and unhealthy protein levels.
New testing instrumentation developed by Antonia Garcia and John Schneider promises to make the procedure less costly and produce results in less tim... Read More
Low-cost vaccines that may have helped prevent the kind of salmonella outbreak that has led to the recall of more than a half-billion eggs haven't been given to half of the nation's egg-laying hens.
The vaccines aren't required in the U.S., although in Great Britain, officials say vaccinatio... Read More
Pathogens make themselves feel at home in the human body, invading cells and living off the plentiful amenities on offer. However, researchers at the Max Planck Institute for Infection Biology, Berlin, together with colleagues at Harvard University, reveal an opposite strategy used to ensure inf... Read More
Those portable electronic gadgets that many of us cant do without are getting more and more high tech. But they still run on old-fashioned batteries. Scientists at the MIT are hoping to change that. Read More
The national's largest egg recall -- 550 million eggs shipped to 22 states -- is underway. But many people may not know how eggs carry salmonella.
According to the Centers for Disease Control and Prevention, salmonella enteritidis -- the strain involved in the recent outbreak -- can be on the... Read More
Individual proteins, and individual translated exons within these proteins, are composed of multiple internested viral protein fragments. This is illustrated for the translated exons of DISC1 , where the different viral contributions are colour coded for each virus or phage. Read More
When it comes to building proteins, it’s in a bacterium’s own best interest to use low-cost components. After all, using an energetically expensive amino acid where a cheaper one would suffice gives your more parsimonious competitors an advantage, and prior studies prove that abundant proteins ...

Virginia Tech College of Engineering researchers have received a $60,000 one-year National Science Foundation grant to study how naturally occurring microbes can best be used to eat away remaining crude oil spilled in the Gulf of Mexico. Their choice of weapon: Geometry.
Fueled by oxygen, nat... Read More
DOE JGI researchers report the first metagenome analysis of a microbial community grown in an anaerobic methanogenic (methane producing) bioreactor. The microbial community is syntrophic, i.e., certain organisms live off the byproducts of others. Read More
By autumn 2009, almost half of the population of Norway had been vaccinated against the pandemic influenza A (H1N1) virus. Many had also been infected by the virus during the summer and autumn outbreaks. The majority of those who were vaccinated or were infected are expected to have developed im... Read More
In a paper published by Nature Geoscience online, Arizona State University researchers Brian Kendall and Ariel Anbar, et al., show that "oxygen oases" in the surface ocean were sites of significant oxygen production long before the breathing gas began to accumulate in the atmosphere. Read More
Studies of the spinal fluid of patients given anti-HIV drugs have resulted in new findings suggesting that the brain can act as a hiding place for the HIV virus. Around 10% of patients showed traces of the virus in their spinal fluid but not in their blood – a larger proportion than previously r... Read More
Prairie dogs, once abundant in the Rocky Mountains and Great Plains, have been decimated in recent decades by plague – a virulent bacterial disease spread by fleas.
Plague outbreaks periodically sweep through large prairie dog towns with thousands of inhabitants, killing virtually the entire ... Read More
Two lines of pest-resistant soybean painstakingly developed by a Michigan State University scientist promise healthier harvests for growers and a little green for the university too.
“Sparta – the Soybean Aphid Shield” is the new trade name for genetics developed by Dechun Wang. The associate... Read More
A University of Illinois metabolic engineer has taken the first step toward the more efficient and economical production of biofuels by developing a strain of yeast with increased alcohol tolerance.
Biofuels are produced through microbial fermentation of biomass crops, which yield the alcohol... Read More
Current HIV treatments do not eradicate HIV from host cells but rather inhibit virus replication and delay the onset of AIDS. However, a new research published in BioMed Central's open access journal, AIDS Research & Therapy describes an innovative approach to eliminate HIV in host by targeted ... Read More
