Immunomagnetic Beads Can Attract Plague Bacteria

Agricultural Research Service (ARS) scientists have used antibody-coated immunomagnetic beads (IMBs) to detect Yersinia pestis, the bacterium that causes bubonic plague.

While similar techniques are often used to detect various bacterial species, the methods must be altered to suit specific p... Read More

Will going gluten free mess up your gut bacteria?

Yes, going gluten free is trendy. And foregoing products made from wheat like bread, cookies, cakes and other processed foods is necessary for people with celiac, an auto-immune problem caused by gluten, a protein in wheat. But when there’s trendy, there’s always folks ready to trash the trend n... Read More

Of Terms in Biology: Metabolomics and Metabonomics

What is metabolomics? Oh, that's easy. It's the study of the metabolome. Very good. Now, what is the metabolome?

* the collection of all metabolites in a biological organism, which are the end products of its gene expression. (Source)
* the complete set of small-molecule metabolites ... Read More

Flu Pandemics May Lurk in Frozen Lakes

The next flu pandemic may be hibernating in an Arctic glacier or frozen Siberian lake, waiting for rising temperatures to set it free. Then birds can deliver it back to civilization.

New research suggests an influenza virus could go into hiding in the ice when earlier generations of humans, b... Read More

Bacteria used to create ethanol for biofuels

US scientists claim to have successfully used bacteria to create cheap, environmentally-friendly biofuels.

According to research presented at the annual general meeting of the American Society for Microbiology, these microscopic organisms are "biological factories" that can serve as alternati... Read More

Drug Experiment Performed On Atlantis

Astronauts on the space shuttle Atlantis are taking a small amount of time from their work servicing the Hubble Space Telescope to tend a commercial drug experiment aimed at finding a vaccine against a deadly staph infection that plagues hospital patients.

The astronauts essentially have to t... Read More

Scientists develop tool to gauge bad breath

Know someone whose breath could peel the paint off a wall?

Then consider the OkaytoKiss - a device that gauges bad breath that was recently invented by scientists at Tel Aviv University.

The pocket-sized breath test measures malodorous bacteria in your mouth. A blue result suggests you nee... Read More

Bacteria Help Form Clouds

Germs really are everywhere: Bacteria, fungal spores and other biological detritus have been found in clouds and likely help to form the cores of cloud droplets, scientists have found.

The study of the role that these biological particles play in cloud formation could help refine one of the b... Read More

Schools Close as Spike in Swine Flu Cases Hits Japan

In a sudden surge that took Asian health officials by surprise, the Japanese health ministry confirmed on Monday at least 125 new cases of the A(H1N1) virus — or swine flu — in the country's western prefectures of Osaka and Hyogo.

Nanobot Uses Bacteria Swarm for Propulsion

Canadian researcher Sylvain Martel has developed a ultra tiny machine that can be propelled and steered through a swarm of 3,000 bacteria.

The tiny device, which measures just 300x300 microns, contains a solar cell, communications circuit and sensor. By sensing pH levels and sharing them via ... Read More

Ultra Sound Weapons Knock Out Algal Blooms

Scientists at the University of Hull, UK, think they have found a way to put a stop to red tide by exposing them to blasts of ultrasound. Michiel Postema and his colleagues tested three different frequencies on a particularly harmful species of blue-green algae, Anabaena sphaerica, which can cau... Read More

Oregon researchers isolate RNA from specific cells using fruit flies

A team of University of Oregon biologists, using fruit flies, has created a way to isolate RNA from specific cells, opening a new window on how gene expression drives normal development and disease-causing breakdowns.

While DNA (deoxyribonucleic acid) provides an identical genetic blueprint ... Read More
