One more step towards cultivating bacteria in the lab

Taking a major step to grow previously uncultivable bacteria in the lab, scientists at Northeastern University have come closer to developing a new generation of highly effective antibiotics.

The researchers examined bacterial communities enveloping particles of sand and identified chemicals ... Read More

Your Fat May Help You Heal: Researcher Extracts Natural Scaffold for Tissue Growth

It frequently happens in science that what you throw away turns out to be most valuable. It happened to Deepak Nagrath, but not for long.

The Rice assistant professor in chemical and biomolecular engineering was looking for ways to grow cells in a scaffold, and he discarded the sticky substan... Read More

Scientists Create Rainbow of Fluorescent Probes

Scientists at Carnegie Mellon University's Department of Chemistry and Molecular Biosensor and Imaging Center (MBIC) are advancing the state-of-the-art in live cell fluorescent imaging by developing a new class of fluorescent probes that span the spectrum -- from violet to the near-infrared. The... Read More

How Cells Recognize Viral Toxins

For many years it's been known that the fever, achiness and other symptoms you feel during the flu are triggered by a viral molecule that travels through the body acting like a toxin.

But what scientists haven't understood is how this molecule -- known as double-stranded RNA -- is recognized ... Read More

Is circovirus DNA infectious?

The US Food and Drug Administration does not want Rotarix, the rotavirus vaccine, to be used because it contains porcine circovirus 1 DNA. If complete copies of the circovirus genome were present, would they constitute a potential threat to recipients? Put another way, is circovirus DNA infectio... Read More

Bacteria Patterns Aid Carbon Fixation

Harvard Medical School researchers have discovered that the organelles responsible for carbon fixation within cyanobacteria organize themselves in predictable patterns—a finding that could help researchers engineer more efficient designer bacteria. Read More

Northeastern University researchers discover new path to antibiotics

Scientists at Northeastern University have taken a major step towards being able to grow previously uncultivable bacteria in the lab, the potential key to developing a new generation of highly effective antibiotics.

Examining bacterial communities enveloping particles of sand, the Northeaster... Read More

Rapid Development of Drug-Resistant 2009 H1N1 Influenza Reported in Two Cases

Two people with compromised immune systems who became ill with 2009 H1N1 influenza developed drug-resistant strains of virus after less than two weeks on therapy, report doctors from the National Institute of Allergy and Infectious Diseases (NIAID), part of the National Institutes of Health. Doc... Read More

Clinical Trial Results Demonstrate Copper Reduces MRSA and VRE in Hospital Rooms

Recent clinical tests demonstrate that antimicrobial copper is effective in significantly reducing the bacterial load in intensive care unit (ICU) patient rooms and on many individual objects in those rooms. Results from a U.S. Department of Defense-funded clinical trial assessing the ability of... Read More

How 1918 flu antibodies fend off swine flu

"The absence of a sugary viral shield could explain why immune responses to the 1918 influenza virus also work against the 2009 H1N1 (swine flu) pandemic strain.

Researchers have found that the two viruses, although separated in time by nearly a century, are structurally similar in a region t... Read More

Oral sex virus 'causing throat cancer'

A common virus spread through oral sex may be triggering a steep rise in types of throat cancer, researchers have warned.

Human Pappillomavirus - known as HPV - is the main cause of cervical cancer, although most infections clear with little or no symptoms.

But after cases of oropharyngeal... Read More

Skloot there it is! HeLa Cells and the Colbert Nation

Science writer Rebbecca Skloot recently appeared on the Colbert Nation to discuss her new book The Immortal Life of Henrietta Lacks. When Henrietta Lacks was diagnosed with cancer in 1951, doctors took her cells and immortalized them in test tubes. Since then these cells have led to signi... Read More

Community-acquired MRSA becoming more common in pediatric ICU patients

Once considered a hospital anomaly, community-acquired infections with drug-resistant strains of the bacterium Staphylococcus aureus now turn up regularly among children hospitalized in the intensive-care unit, according to research from the Johns Hopkins Children's Center.

The Johns Hopkins ... Read More

Watch Man-Controlled Bacteria Build A Nanoscale Pyramid

Forget nanobots. Who needs ‘em? Since apparently we can now directly control live bacteria and make them do our bidding. I’m in awe. The feat was accomplished – and extensively documented in the video above – by researchers at the NanoRobotics Laboratory of the École Polytechnique de Montréa... Read More

Rubber from Microbes

Working with Goodyear, biotechnology company Genencor has been engineering bacteria that make isoprene--the chemical used to make tire rubber--from sugars derived from biomass. But ramping up microbial production of isoprene to such a scale that it can compete with petroleum-derived rubber has p... Read More

The postmortem on pregnancy and H1N1 flu

As early as last July, federal health officials warned doctors and pregnant women that the H1N1 (swine) flu virus appeared especially hazardous for pregnant women. In the fall, officials urged pregnant women to be vaccinated against H1N1, although surveys showed that pregnant women often hesitat... Read More

Facebook 'linked to rise in syphilis' in Britain

UK Professor Peter Kelly, director of public health in Teesside, claims his research staff has found a link between social networking sites and the spread of Syphilis, especially among young women.

According to Kelly, "there has been a fourfold increase in the number of syphilis cases detecte... Read More

Biofilm Production Aids Campylobacter Survival

Scientists at the Institute of Food Research have found a way that the foodborne pathogen Campylobacter can survive in the environment.

Campylobacter is the main cause of food poisoning in Europe and America, most often contracted from eating under-cooked chicken or turkey. It is estimated th... Read More

Scientists Uncover Vast Microbial Diversity of Carnivorous Pitcher Plant

The microbial ecosystem inside the carnivorous pitcher plant is vastly more diverse than previously thought according to research published in the March 2010 issue of the journal Applied and Environmental Microbiology.

Researchers from Louisiana State University used genomic fingerprinting te... Read More
