New nanotechnology material kills antibiotic-resitant bacteria

Doctors are not well armed in the fight against antibiotic-resitant bacteria. It is very difficult – or, in the worst case, impossible – to fight such infections. A team of researchers in Münster has now developed a unique nanotechnology material that kills antibiotic-resitant bacteria.

Human Trials for Salmonella Vaccine Developed in Space May Happen By 2010

There has been debate among Americans regarding the benefits of space-based research. That debate may well be over due to a recent announcement from the Astrogenetix Company based in Austin, Texas. A vaccine for salmonella may go to human trials as early as next year. If these trials are appr... Read More

Swine Flu Vaccine--Too Little, Too Late

As health care workers in the U.S. gear up for the flu season, they facea paradox: on the one hand, they will have too little vaccine against the novel influenza A (H1N1) strain to protect the entire population; on the other, some people will resist the shots that are offered to them. Sadly, bot... Read More

Pathogenic E. Coli Pervasive In Stream-water Samples With Low Concentrations Of Fecal Indicator Bacteria

Bacteria commonly used to indicate health risks in recreational waters might not be so reliable after all. Pathogenic E. coli were pervasive in stream-water samples with low concentrations of fecal indicator bacteria.

This is one of the unexpected findings from recent research that may affect... Read More

Species-jumping Diseases: Better Global System Needed To Effectively Prevent, Detect, Respond To Zoonotic Infectious Diseases

Significant weaknesses undermine the global community's abilities to prevent, detect early, and respond efficiently to potentially deadly species-crossing microbes, such as the pandemic H1N1 influenza virus sweeping the globe, says a new report from the Institute of Medicine and National Researc...

Swine flu could kill millions

UN report says pandemic may result in anarchy unless western world pays for antiviral drugs and vaccines

The swine flu pandemic could kill millions and cause anarchy in the world's poorest nations unless £900m can be raised from rich countries to pay for vaccines and antiviral medicines, says... Read More

AIDS-like retrovirus threatens Australia's koalas with extinction

Koalas (Phascolarctos cinereus) may be one of the world's cuter critters, but that doesn't mean they have it easy. Not only have koala populations become heavily fragmented due to habitat loss, they face numerous threats that they never encountered before: household cats and dogs frequently kill... Read More

Debate Flaring Over Grants for Research

Managers at the National Institutes of Health are increasingly ignoring the advice of scientific review panels and giving hundreds of millions of dollars a year to scientists whose projects are deemed less scientifically worthy than those denied money.

Many of the favored recipients are “new ... Read More

Discovery could improve hepatitis C treatment

Walter and Eliza Hall Institute researchers are part of an international team that has discovered a genetic variation that could identify those people infected with hepatitis C who are most likely to benefit from current treatments.

Dr Melanie Bahlo and Dr Max Moldovan from the institute's Bi... Read More

Frog Fungus Hammering Biodiversity Of Communities

A microscopic fungus by the name of Batrachochytrium dendrobatidis, or Bd, is killing Central American frogs as a rate that is more alarming that once believed.

"The fungus is devastating to frogs because it infects the skin, a much more important organ in amphibians than in other vertebrate... Read More

New Drugs May Attack Flu, but Not in Time

Besides the vaccines aimed at preventing flu, new drugs are on the way to treat it once it strikes. But it is not clear whether they will arrive in time to make a difference in thwarting the H1N1 flu pandemic.

New drugs are needed, researchers say, because there are now only four approved flu... Read More

Technique Identifies New Drug and Vaccine Targets in Record Time

Howard Hughes Medical Institute (HHMI) researchers have devised a new method called Tn-seq for rapidly identifying genes that are crucial for survival of bacteria – cutting the time it takes to pinpoint promising new vaccine and drug targets from years to weeks.

In an article published in th... Read More

Seasonal Cold or Swine Flu? Moms Face Tough Calls

Parents like the author of this article are facing a series of hard choices as flu season begins this fall...

I sent my 11-year-old son to school today with a stuffy nose and mild cough, as I've done countless times in the past. Now, though, I'm wondering whether I should have kept him home. ... Read More

Lack of Sleep Increases the Risk of Catching a Cold.

Researchers found that people who averaged less than 7 hours sleep per night were more susceptible to rhinovirus infection. Read More

Benefit and Doubt in Vaccine Additive

Are Americans obligated to use an unproven vaccine to help protect people in other countries from the flu pandemic?

That is the crux of a debate over adjuvants — a class of substances that somewhat mysteriously increase the potency of vaccines. Early studies suggest that adjuvants (pronounce... Read More

Hepatitis B Vaccinations at Birth Are Tied to Less Liver Cancer, Taiwan Study Finds

Vaccinating children against hepatitis B at birth can significantly reduce liver cancer in older children, a new study in Taiwan has found.

Hepatitis B vaccination at birth became standard policy in Taiwan in 1984. For the 20-year follow-up study, scientists at the National Taiwan University... Read More

Better world: Vaccinate your children

If you have ever taken a stroll through an old graveyard, you may have winced at the surprising number of tombstones bearing witness to the young age of their occupants. In the past, around 1 in 3 children died before their fifth birthday. It was common for children to perish from diphtheria, me... Read More

H1N1 Clinicians Questions and Answers

This briefing from the CDC covers common clinician questions regarding who should receive the H1N1 vaccine, how providers can receive the vaccine and information on priority target groups. Read More

'Evolutionary forecasting' for drug resistance

Rice University biochemists are developing a system of "evolutionary forecasting" to better understand the mechanisms of antibiotic resistance.

"Our goal is to show antibiotic makers which sets of genes a pathogen will modify to become drug-resistant," said Yousif Shamoo, the principal invest... Read More

New chemically-activated antigen could expedite development of HIV vaccine

Scientists working to develop a vaccine for the human immunodeficiency virus (HIV) report they have created the first antigen that induces protective antibodies capable of blocking infection of human cells by genetically-diverse strains of HIV. The new antigen differs from previously-tested vacc... Read More
