Cigarettes might be infectious

The tobacco in cigarettes hosts a bacterial bonanza — literally hundreds of different germs, including those responsible for many human illnesses, a new study finds.

“Nearly every paper that you pick up discussing the health effects of cigarettes starts out with something to the effect that s... Read More

Lab-grown Liver Cells Provide Model for Hepatitis C Infection

Howard Hughes Medical Institute researchers and their colleagues at the Rockefeller University have developed a new method for growing human liver cells outside the body. Using the new cell culture system, scientists can now study hepatitis C virus in the lab over a period of weeks – which may ... Read More

Study recommends better handling of milk in restaurants

One-third of samples of milk and dairy products analysed in various restaurants exceed the microbe contamination limits set by the European Union, according to a study carried out by researchers from the University of Valencia (UV). The experts advise against keeping milk in jugs and suggest tha... Read More

The face of first contact: What aliens look like

Tentacled monsters, pale skinny humanoids, shimmery beings of pure energy... When it comes to the question of what alien life forms might look like, we are free to let our imagination roam. The science-in-waiting of extraterrestrial anatomy has yet to acquire its first piece of data, so nobody k... Read More

Firm Brings Gene Tests to Masses

The new movie “Extraordinary Measures” is based on the true story of a father who starts a company to develop a treatment for the rare genetic disease threatening to kill two of his children before they turn 10.

Now, a Silicon Valley start-up is making the bold claim that it can help eradica... Read More

Our viral DNA

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

Asexual Solution To Parasite Problem

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

Like-minded fellows

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

Stopping Bacterial Infections Without Antibiotics

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

MMR scare doctor 'acted unethically', panel finds

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

Flu in pregnancy changes fetal brain

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

Is that staph on your sweater? 10 germ hideouts

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

Algal power not so green after all, yet

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

Chlorhexidine Cuts Risk of Surgical Infections

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

Gastric Ulcer Bacteria Turn Immune Defense Inwards

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

Antibiotics Might Team Up to Fight Deadly Staph Infections

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

Bacteria Transformed into Biofuel Refineries

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

XMRV infection is enhanced by prostatic protein fragments

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
