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
Neurological and infectious disease experts at Rush University Medical Center are testing a new drug therapy for the treatment of individuals with West Nile fever or suspected central nervous system infection due to the West Nile virus. Rush is the only site in the Midwest enrolling patients int... Read More
A CONVENIENT type of killer white blood cell could make organ rejection a thing of the past.
The cells suppress the immune response in the livers of mice, without affecting the rest of the immune system. Humans have this type of blood cell, so it might be possible to create immune-tolerant or... Read More
The placement of alcohol-based hand disinfectants in businesses can reduce illness and absenteeism amongst the work force. A study published in the open access journal, BMC Infectious Diseases, has found that incidences of absenteeism in public administrations due to the common cold, fever and c... Read More
When the journal Science published an attention-grabbing study last fall linking chronic fatigue syndrome to a recently discovered retrovirus, many experts remained skeptical — especially after four other studies found no such association.
Now a second research team has reported a link betw... Read More
