The instructions encoded into DNA are thought to follow a universal set of rules across all domains of life. But researchers report in the May 23 issue of Science that organisms routinely break these rules.
The finding has implications for the design of synthetic life: by designing organisms ... Read More
Researchers have identified the evolutionary origins of human herpes simplex virus (HSV) -1 and -2, reporting that the former infected hominids before their evolutionary split from chimpanzees 6 million years ago while the latter jumped from ancient chimpanzees to ancestors of modern humans -- H...

Colorectal cancer develops in what is probably the most complex environment in the human body, a place where human cells cohabitate with a colony of approximately 10 trillion bacteria, most of which are unknown. At the 2014 American Association for Cancer Research Annual Meeting in San Diego, re... Read More
Scientists have modified mosquitoes to produce sperm that will only create males, pioneering a fresh approach to eradicating malaria. Since 2000, increased prevention and control measures have reduced global malaria mortality rates by 42 per cent, but the disease remains a prevalent killer espec... Read More
In the United States, approximately 40,000 people die every year due to pancreatic adenocarcinoma, making it the fourth leading cause of cancer related death. Patients diagno... Read More
Hand washing is thought to be effective for the prevention of transmission of
Diarrhea pathogens. However it is not conclusive that hand washing with soap is more
Effective at reducing contamination with bacteria associated with diarrhea than using water only. Read More
Using an experimental technique new to the dengue field, the labs of Ralph Baric, PhD, and Aravinda de Silva, PhD, showed that a molecular hinge where two regions of a protein connect is where natural human antibodies attach to dengue 3 to disable it. The finding, published in the Proceedings of... Read More
According to CNN,a long-range business jet with an isolation pod left the United States for Liberia, where it will evacuate two Americans infected with Ebola.
Twitter exploded with questions about the deadly virus, which according to the World Health Organization is believed to have killed hu... Read More
In its early days, ca. 1945-1965, molecular biology was a particularly collegial undertaking, characterized by free sharing of research data and a relative lack of egotistical behavior. The reason for this marvel may well have been that there was so much to discover—so many low hanging fruits—th... Read More
A boy with cystic fibrosis develops a chronic and potentially deadly Burkholderia dolosa infection in his lungs. Varieties of genetic mutations allow some strains of the bacteria to survive the dual assaults from his immune system and antibiotics, while others perish. Eventually, the strongest m... 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
Dr. Tom Solomon is Director of the Institute for Infection and Global Health at the University of Liverpool. In this video he speaks with Vincent Racaniello about the 2014 outbreak of Zaire ebolavirus in West Africa. Dr. Solomon discusses why the epidemic has spread, how it might be curtailed, t...

A graduate student came to my office recently to say that she was increasingly bothered by anxiety and the ‘terror’ of having to speak at laboratory meetings. She had also learned a month ago that she was expected to lecture to a class organized by her mentor. The thought of having to lecture to... Read More
Lyme disease is a stealthy, often misdiagnosed disease that was only recognized about 40 years ago, but new discoveries of ticks fossilized in amber show that the bacteria which cause it may have been lurking around for 15 million years – long before any humans walked on Earth.
The findings w... Read More
Banana lovers take note: The world's supply of the fruit is under attack from a fungus strain that could wipe out the popular variety that Americans eat. "It's a very serious situation," said Randy Ploetz, a professor of plant pathology at the University of Florida who in 1989 originally discove... Read More
Cambridge scientists have uncovered the mechanism by which bacteria build their surface propellers (flagella) – the long extensions that allow them to swim towards food and away from danger. The results, published this week in the journal Nature, demonstrate how the mechanism is powered by the s... Read More
Speedy analysis reveals mutations, insights into outbreak, along with clues to origin, spread.
Responding rapidly to the deadly outbreak of Ebola virus disease (EVD) in West Africa, a team of researchers from the Broad Institute and Harvard University, working with the Sierra Leone Ministry o... Read More
The traditional light microscope is bulky and expensive. Dr Tri Phan and Dr Steve Lee from the Garvan Institute of Medical Research and Australian National University used gravity to manufacture high-performance polymer lenses. These can be seamlessly integrated with 3D printing and mini-LEDs to... Read More
Methicillin-resistant S. aureus (MRSA) constitutes approximately 50% of clinical S. aureus isolates and is most commonly the result of production of a mutated pencillin-binding protein, PBP2a, which is able to carry out essential cell wall synthesis functions while maintaining a low-affinity for...

If a sexually active woman wants to protect herself from unwanted pregnancy and HIV using a single method, she has always been limited to condoms. A new paper, released today in PLOS ONE details a first-of-its-kind device that provides an alternative.
