In the experiment, published this week in Nature Nanotechnology, the researchers slathered one side of a sheet of rubber with the bacterial spores. When the sheet dried it curled up, much like a leaf does after it falls from a tree. Increasing the humidity caused the sheet to straighten out agai... Read More
Sulfonated and non-sulfonated cyanines exhibit very similar fluorescent properties. Non-sulfonated cyanines must be dissolved in organic co-solvent (DMF or DMSO) prior to use, and added to a solution of target molecule in aqueous buffers. Recommended volume of co-solvent should be 10% for Cy3, C... Read More
The virus causing Middle East respiratory syndrome emerged in 2012. It does not spread readily between people, but there are fears it could cause a pandemic if it ever starts. It has killed 76 of the 178 people known to have caught it so far, and there is no specific treatment. Shibo Jiang at Fu... Read More

In recent weeks, China has seen a spike in H7N9 cases and experts are worried that infections will gather pace as the country celebrates the Lunar New Year this week - a peak time for travel and for poultry sales. In January alone, 19 deaths and 96 human cases have been reported, according to fi... Read More
BERKELEY — People infected with the Human Immunodeficiency Virus (HIV) can stave off the symptoms of AIDS thanks to drug cocktails that mainly target three enzymes produced by the virus, but resistant strains pop up periodically that threaten to thwart these drug combos. Researchers at the Unive... Read More
Gut bugs can change the way our brains work, offering new ways to relieve problems like stress, anxiety and depression, say two leading professors
We acquire our intestinal microbes immediately after birth, and live in an important symbiotic relationship with them. There are far more bacteria... Read More
Most people try to avoid catching the flu by taking precautions such as washing their hands often, avoiding people who are already sick, or getting a flu shot.
However, scientist are giving volunteers the flu on purpose by squirting the virus up their nose, all in the name of science.
Why woul... Read More
Multiple sclerosis (MS), a central nervous system disease that often leads to paralysis and vision problems, affects approximately 2.3 million people worldwide and has no cure. Though no one knows what triggers MS, researchers have long suspected that a combination of genetic and environmental f... Read More
In a fascinating story that was presented on NPR by Nell Greenfieldboyce we learn that the source of the Justian Plague (541-543AD) was recently identified by sequencing blood extracted from the dental pulp of the teeth associated with two skeletons recovered from Munich. For many years it was... Read More
Gut bacteria in premature infants don't come from their mothers, but from microbes in the neonatal intensive-care unit (NICU), a new study finds. Babies typically get their gut bacteria from their mothers during childbirth. Premature infants, however, receive antibiotics during their first week ... Read More
It's an age-old search: the secret to eternal youth. For centuries, the dream of a single factor that may increase our lifespan has been at the forefront of many legends, excursions, and of course, advertising campaigns. But while this search has been fruitless for the majority of us, there is h... Read More

From the discovery of the first Neanderthal skull in a Belgian cave in 1826, a bone of contention among Homo sapiens has been the extent of our relationship to Homo neanderthalis, who disappeared from the fossil record ~30,000 years ago. Like scrappy cousins we'd rather not claim, we've attempte... Read More
Scientists have discovered the use of a simple single-celled amoeba to understand the function of human proteins in causing Alzheimer’s disease.
The new study, published in the Journal of Cell Science today (Friday 24 January) by researchers at Royal Holloway, University of London and the Ins... Read More
Scientists at Scripps Institution of Oceanography at UC San Diego have developed a new genetic platform that allows efficient production of naturally occurring molecules, and have used it to produce a novel antibiotic compound.
“In my opinion, the new synthetic biology technology we develope... Read More
Researchers from Germany have identified the mechanism by which Salmonella infections can reduce the incidence of asthma in mice. The research, which appears ahead of print in the journal Infection and Immunity, opens up new avenues of research that could lead to treatments.

Much like how a snowplow is needed to clear streets of heavy snow, cells employ a set of genes to clear away misfolded proteins, to prevent them from accumulating and destroying the cell.
For the first time, Cornell researchers have demonstrated how a gene called SEL1L plays a critical role i... Read More
Mechanisms that determine the size of plants have fascinated plant scientists of all times, however they are far from understood. An international research team led by plant scientists from VIB and Ghent University report an important breakthrough in the scientific journal The Plant Cell. They i... Read More
