A team of researchers led by King's College London has for the first time identified a new gene which may have the ability to prevent HIV, the virus that causes AIDS, from spreading after it enters the body.
Published in Nature today, the study is the first to identify a role for the human MX... Read More
Amidst the outrage, puzzlement and theories caused by the finding of genetically-modified wheat in an Oregon field, USDA is considering whether to commercialize another dinnertime staple–the potato.
Last month, Idaho-based J.M. Simplot asked the Agriculture Department to grant a deregulated s... Read More
A common soil-dwelling microbe appears to have a sense of touch, researchers report.
A new study finds that Bacillus mycoides, a bacterium known to science since 1842, responds to forces and curvature in the medium on which it’s growing.
The microbe’s ability to respond to subtle changes i... Read More
Purple bacteria contain pigments that allow them to use sunlight as their source of energy, hence their color. Small as they are, these microbes can teach us a lot about life on Earth, because they have been around longer than most other organisms on the planet. University of Miami (UM) physicis... Read More
In Europe alone, more than 25,000 people die each year from infections caused by multi-resistant bacteria. Researchers from University of Copenhagen have now developed and characterized a substance that quickly and effectively kills the virulent bacteria. The substance employs a multifunctional ...

Mating and meiosis – the specialized cell division that reduces the number of chromosomes in a cell – are related, but in most yeasts they are regulated separately. Not so in Candida lusitaniae, where the two programs work in unison, according to a new study in Nature. Comparison with other spec... Read More
DNA carries out its activities "diluted" in the cell nucleus. In this state it synthesises proteins and, even though it looks like a messy tangle of thread, in actual fact its structure is governed by precise rules that are important for it to carry out its functions. Biologists have studied DNA... Read More
Scientists from Singapore’s Nanyang Technological University (NTU) have discovered a key process during the invasion of the blood cell by the Malaria parasite, and more importantly, found a way to block this invasion.
With this new knowledge, NTU is looking to collaborate with the industry on... Read More
"Pharmaceutical residues are becoming increasingly a problem for the environment. Sewage plants do not decompose these substances completely. The problem will worsen if one considers, for example, the rising proportion of elderly people in our society who actually account for the increased consu... Read More
Making fat cells immortal might seem like a bad idea to most people, but for a team of University of Iowa scientists it was the ideal way to study how the interaction between bacteria and fat cells might contribute to diabetes.
The connection between fat, bacteria, and diabetes is inflammatio... Read More
Researchers are gathering this week to debate the most humane methods of dispatching lab animals, which are primarily rodents. Killing research animals is one of the most unpleasant tasks in science, and it is imperative to do it as humanely as possible. But researchers who study animal welfare... Read More
Researchers have identified components in Clostridium difficile (C. diff) that may lead to new diagnostic tools, and ultimately more timely and effective treatment for this often fatal infection. C. diff is a spore-forming bacterium that causes severe diarrhea and is responsible for 14,000 death... Read More
Slime molds may not have brains, but that isn't preventing some computer scientists from investigating them for their potential as novel, unconventional computers. A slime mold consists of a single cell containing millions of nuclei, and forms a network of protoplasmic tubes to move toward its f... Read More
So far there have only been isolated cases of bird flu in humans, and no widespread transmission as the H5N1 virus can’t replicate efficiently in the nose. The new study, using weakened viruses in the lab, supports the conclusions of controversial research published in 2012 which demonstrated th... Read More
The Chinese Government seems committed to reforming food safety laws and investing in vital surveillance and monitoring systems, but experts say implementing those efforts could be challenging.
Published in the journal The Lancet, a new study suggests that the rapidly growing Chinese economy ... Read More
Scientists are great at growing E. coli in the lab. They know exactly under which conditions various strains thrive. Unfortunately, there is only so much that can be learned from the bacteria’s behavior in an ideal, isolated and ultimately unrealistic environment. That is why a group of research... Read More
The World Health Organization says no evidence has emerged to show that a type of bird flu which has killed two Chinese men can be transmitted between people.
Two men in Shanghai, aged 87 and 27, fell sick in late February. A woman in Anhui province also contracted the virus in early March an... Read More
Visceral leishmaniasis, also called kala-azar, strikes 400,000 people every year and kills around 1 in 10 of its victims. The leishmania parasite, Leishmania donovani, has proven difficult to treat, in part because a large percentage of patients who take the drug of choice, miltefosine, relapse ... Read More
Researchers at Singapore's Institute of Bioengineering and Nanotechnology (IBN) and California's IBM Research -- Almaden (IBM) have discovered a new, potentially life-saving application for polyethylene terephthalate (PET), which is widely used to make plastic bottles. They have successfully con... Read More
Escherichia coli – a friendly and ubiquitous bacterial resident in the guts of humans and other animals – may occasionally colonize regions outside the intestines. There, it can have serious consequences for health, some of them lethal.
In a new study conducted in assistant professor Melha M... Read More
