Since the introduction of highly active antiretroviral therapy in the mid-1990s, HIV infection has evolved from a near-certain death sentence to a manageable, chronic disease. Still, ... Read More
Nearly two years after the Deepwater Horizon disaster gushed millions of barrels of oil into the Gulf of Mexico, tar balls from the spill still turn up on Alabama's shores after storms. Now, one researcher is recommending that people steer clear of these tar balls after studies find them chock-f... Read More
Scientists have created spermless mosquitoes in an effort to curb the spread of malaria.
Experts say that this is an important first step toward releasing sterile males into the wild to reduce the size of mosquito populations.
Malaria kills around one million people worldwide every year, a... Read More
Federal health investigators landed in St. Louis Friday to help determine the source and scope of the E. coli outbreak that has so far sickened 23 people across the region.
There were no new illnesses reported on Friday.
Four scientists from the U.S. Centers for Disease Control and Preve... Read More
Beer drinkers know that hops are what gives the drink its bitterness and aroma. Recently, scientists reported that the part of hops that isn’t used for making beer contains healthful antioxidants and could be used to battle cavities and gum disease. In a new study in ACS’ Journal of Agricultural... Read More
NEARLY half of consumers ignore use-by dates on food with experts warning they are putting their health at risk, a report has revealed.
Dr Wayne Anderson, food science and standards director, said food may be badly contaminated even if it appeared good enough to eat.
"We would caution peop... Read More
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.

One way to avoid getting sick while traveling is to only eat fruit that you peel yourself, since plants can filter out bacteria and prevent it from traveling throughout their tissues. Well, why not apply this principle to filtering water directly? A team of scientists have done just that, testi... Read More
Researchers have debated for more than two decades the likely impacts, if any, of global warming on the worldwide incidence of malaria, a mosquito-borne disease that infects more than 300 million people each year. University of Michigan ecologists and their colleagues are reporting the first har... Read More
We’re in a sad and weird place in biomedical science. In the 1940’s we got penicillin, in the following 30 years another 13 different classes of antibiotic were introduced. Since 1970 the number of new classes has dropped to a worrying 2. Since then we have found new ways to arrange the deckcha... Read More
The FDA has approved a new compound for the treatment of acute lymphoblastic leukemia (ALL) patients who are allergic to asparaginase derived from Escherichia coli.
The agency gave the okay to asparaginase Erwinia chrysanthemi (Erwinaze) as a replacement for E. coli-derived asparaginase or pe... Read More
Lessons learned from Florence Nightingale could prevent the spread of harmful bugs by allowing "friendly" bacteria into hospitals, an expert has claimed.
Sterile conditions in wards and operating theatres may be doing more harm than good by wiping out organisms that keep dangerous microbes at b... Read More
Tel Aviv University researchers have developed a computational model that explains how bacteria move in a swarm, which can be applied to man-made technologies, including computers, artificial intelligence, and robotics.
Ph.D. student Adi Shklarsh of TAU has discovered how bacteria collectivel... Read More
The genome of Medicago, a close relative of alfalfa and a long-established model for the study of legume biology, has been sequenced by an international team of scientists, capturing around 94 per cent of its genes.
The research gives new insights into the evolution of the Papilionoid subfami... Read More
Bacterial cells are fundamentally different to the cells of multicellular animals such as humans. They are far smaller, with less internal organisation and no nucleus (they have DNA but it is not packaged safely within a membrane). Because of this bacteria are almost exclusively single-celled or... Read More
Although scientists have known for centuries that many bacteria produce hydrogen sulfide (H2S) it was thought to be simply a toxic by-product of cellular activity. Now, researchers at NYU School of Medicine have discovered H2S in fact plays a major role in protecting bacteria from the effects of... Read More
