The Jelly Roll of Life

We know that life on earth is incredibly diverse. It can survive deep in the trenches of the ocean and in the frozen permafrost of the arctic. Surely we have much to learn from the study of life, but we also have much to learn about the virus. Even though they are not considered living things, t... Read More

More than glitter: Scientists explain how gold nanoparticles easily penetrate cells, making them useful for delivering drugs

A special class of tiny gold particles can easily slip through cell membranes, making them good candidates to deliver drugs directly to target cells.

A new study from MIT materials scientists reveals that these nanoparticles enter cells by taking advantage of a route normally used in vesicle-... Read More

HIV, malaria, and tuberculosis: Success of the Millennium shown in most comprehensive study to date

Accelerated progress against the global burden of HIV, malaria, and tuberculosis (TB) has been made since 2000 when governments worldwide adopted Millennium Development Goal 6 to combat HIV/AIDS, malaria, and TB. New estimates from a major new analysis show that worldwide, the number of people l... Read More

New type of heredity described in Paramecia, linked to epigenetics

Considered as an obsolete theory for many years, the transmission of acquired traits has returned to the forefront of debate thanks to the development of epigenetic research. In this context, a team of researchers has described how in Paramecia, mating types are transmitted from generation to ge... Read More

Salvaging Science from Stricken Mars Moon Probe: A Scientist's View

Russian engineers are scrambling to save the Phobos-Grunt spacecraft amid ever-bleaker signs the mission may be lost. The probe was launched uneventfully Nov. 8, but soon afterward its thruster failed to fire to send it on a course toward Mars, leaving the spacecraft stranded in Earth orbit.

Incidence of childhood tuberculosis could be 25 percent higher than previous estimates

New estimates indicate that over 650,000 children develop tuberculosis (TB) every year in the 22 countries with a high burden of the disease -- almost 25 percent higher than the total number of new cases worldwide estimated by WHO in 2012. The research also suggests that about 15 million childre... Read More

Land of the bacteria-eaters

For hospital workers an outbreak of harmful bacteria in the wards is a nightmare, but what gives bacteria nightmares?

Perhaps the prospect of being eaten alive by a kind of viral parasite called a bacteriophage (bacteria eater): unlike antibiotics, which some bacteria have evolved a resistanc... Read More

Artificial magnetic bacteria "turn" food into natural drugs

Scientists from the University of Granada have successfully created magnetic bacteria that could be added to foodstuffs and could, after ingestion, help diagnose diseases of the digestive system like stomach cancer. These important findings constitute the first use of a food as a natural drug an... Read More

Deadly Bacteria Lurk in Deepwater Horizon Tar Balls

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

Plant Pathogen Silences Host’s Immune Genes

As more and more information becomes available, one marvels (and also frets) at the sophisticated strategies that pathogens have evolved in order to evade their hosts’ defense mechanisms. Many pathogens of plants and animals deliver effectors into their hosts in order to suppress immune response... Read More

FDA Panel Votes to Expand Use of Pneumococcal Vaccine to Adults

An FDA advisory committee has voted 14-1 in favor of expanding the indication for the pneumococcal 13-valent conjugate vaccine (Prevnar 13) to include use in adults 50 and older.

Currently the Pfizer vaccine is approved only for use in children.

The FDA's Vaccines and Related Biologics Adv... Read More

Scientists to Study Novel Treatment for Antibiotic-Resistant Bacterial Infections

The bacteria Enterococcus can cause infections that typically target the digestive tract or bowel; if the bacteria spread, an abdominal abscess or urinary infection could result. Enterococcus also can invade the bloodstream, leading to meningitis, pneumonia or endocarditis — an infection of the ... Read More

Study examines therapeutic bacteria’s ability to prevent obesity

A probiotic that prevents obesity could be on the horizon.

Bacteria that produce a therapeutic compound in the gut inhibit weight gain, insulin resistance and other adverse effects of a high-fat diet in mice, Vanderbilt University investigators have discovered.

“Of course it’s hard to spec... Read More

Ancient genetic material from caries bacterium obtained for the first time

A UAB research concludes that the Streptococcus mutans, one of the principal bacteria causing dental caries, has increased the changes in its genetic material over time, possibly coinciding with dietary changes linked to the expansion of humanity.

Drug Combo Can Sure Hepatitis C in Patients With HIV

A new combination drug therapy cures chronic hepatitis C in most patients also infected with HIV—and without the side effects of current treatments.

The advance is important, researchers say, because about a third of HIV patients in the United States also have hepatitis C. There are an estima... Read More

Viral relics show cancer's 'footprint' on our evolution

Cancer has left its 'footprint' on our evolution, according to a study which examined how the relics of ancient viruses are preserved in the genomes of 38 mammal species.

Viral relics are evidence of the ancient battles our genes have fought against infection. Occasionally the retroviruses th... Read More

On the trail of E. coli outbreak


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

Nearly half of consumers ignore use-by-dates on food

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

Hospitals 'need friendly bacteria'

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

FDA Gives Nod to New Leukemia Treatment‎

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
