Virus-like components of the human genome amount to almost half of our DNA. This would once have been dismissed as mere "junk DNA", but we now know that some of it plays a critical role in our biology. As to the origins and function of the rest, we simply do not know.
The human genome therefo... Read More
Organisms evolved sexual reproduction so they could stay one step ahead of parasites. Or so the theory goes. But what about beasties that make babies without sex? How do they escape infection? A study in the journal Science suggests that for bdelloid rotifers, the answer is blowin’ in the wind.... Read More
Some 350 years ago, a dozen men meeting in the City of London heard a lecture by a young astronomer named Christopher Wren, who would later become the architect of St Paul’s Cathedral. They determined to gather on a regular basis. Inspired by the writing of Sir Francis Bacon, a 17th-century stat... Read More
New research at the A. James Clark School of Engineering could prevent bacterial infections using tiny biochemical machines nanofactories that can confuse bacteria and stop them from spreading, without the use of antibiotics. Read More
Dr Andrew Wakefield's 1998 Lancet study caused vaccination rates to plummet, resulting in a rise in measles - but the findings were later discredited.
The General Medical Council ruled he had acted "dishonestly and irresponsibly" in doing his research.
Afterwards, Dr Wakefield said the cla... Read More
The brains of monkeys whose mothers had flu while pregnant resemble those of people with schizophrenia. The finding backs up studies in people that suggest flu in mothers-to-be affects the brain of the developing fetus.
Previous research had found that the children of women who caught flu whi... Read More
You've worked hard to make your house a beautiful, peaceful haven — but even super-tidy homes can harbor unwelcome germs. In fact, "you're more likely to get sick from a germ in your own house than from any other source," says Kelly A. Reynolds, PhD, an environmental microbiologist at the Univer... Read More
Algae have been touted as a solution to environmental worries over biofuels, but they may be a long way from providing a truly green option.
Unlike maize, soya beans and oilseed rape (canola), algal farms don't take up valuable farmland, so algae-based biofuels don't threaten food supplies. H... Read More

The chemical antiseptic chlorhexidine does a better job than povidone-iodine in reducing the risk of surgical site infections, even in carriers of Staphylococcus aureus, according to two new randomized studies.
Researchers in the U.S. found that chlorhexidine and alcohol, used for preoperativ... Read More
Despite a strong response from our immune defence, the body is unable to rid itself of the bacterium Helicobacter pylori. One reason for this is that this bacterium encourages elements of the immune response to remain in tissue, activating the wrong immune cells. Research results that pave the w... Read More
Researchers at the University of Illinois at Chicago and Israel's Weizman Institute of Science have found that two antibiotics working together might be more effective in fighting pathogenic bacteria than either drug on its own.
Individually, lankacidin and lankamycin, two antibiotics produce... Read More
The bacteria responsible for most cases of food poisoning in the U.S. has been turned into an efficient biological factory to make chemicals, medicines and, now, fuels. Chemical engineer Jay Keasling of the University of California, Berkeley, and his colleagues have manipulated the genetic code ... Read More
Fragments of an abundant protein produced by the prostate form amyloid fibrils that enhance infection of cells by human immunodeficiency virus type 1. These fibrils, called semen-derived enhancer of virus infection (SEVI), have been found to boost infection of prostate cells by the retrovirus XM... Read More

Scientists have long pondered the seeming contradiction that taking broad-spectrum antibiotics over a long period of time can lead to severe secondary bacterial infections. Now researchers from the University of Pennsylvania School of Medicine may have figured out why.
The investigators show ... Read More

A study aimed to measure rates of hand sanitizer use in a hospital entrance foyer four months after a baseline study during New Zealand's influenza pandemic found that of the 743 people observed over one (summer) day in December 2009, 8.2% used the hand sanitizer, which was significantly lower (...

For the past 50 years, scientists have scoured the skies for radio signals from beyond our planet, hoping for some sign of extraterrestrial life. But one physicist says there's no reason alien life couldn't already be lurking among us — or maybe even in us.
