Development of an HIV-1 Specific Microbicide Using Caulobacter crescentus

A recent paper published in PLoS One looks at the strategy of manipulating surface proteins on the aquatic bacterium, Caulobacter crescentus, to prevent HIV infection.

Abstract:

The development of alternative strategies to prevent HIV infection is a global public health priority. Initial e... Read More

Measles still spreads in Europe: who is responsible for the failure to vaccinate?

It is not a secret that the goal of eliminating measles and rubella in Europe will not be met by the targeted year 2010. Over the past 10-12 years, national and international public health authorities have conducted extraordinary efforts that have led to a dramatic reduction in reported measles ... Read More

Protein shows up early in deadly cancer

A newly identified molecular marker of pancreatic cancer may help spot the disease at its earliest stages, when it can be treated more successfully with surgery.

In a report published in the online journal PLoS One, the researchers showed that a specific form of a protein called palladin is p... Read More

A Clamp for Emerging Flu Viruses: Researchers Unravel Secret of Innate Immune Response

When the human body becomes infected with new influenza viruses, the immune system rapidly activates an inborn protective mechanism to inhibit the intruding pathogen. A protein known as Mx plays an important role in this process, keeping the spread of viruses in check. Exactly how Mx accomplishe... Read More

Can a plant virus make you sick?

It has been estimated that approximately one hundred trillion bacteria colonize the human intestine. That’s about ten times the number of cells that constitute the entire human body. These bacteria are believed to have a mutualistic symbiotic relationship with their hosts. What is known about th... Read More

Ocean Bacteria Can Harvest Energy from Sunlight for Survival

Bacteria in the ocean can harvest light energy from sunlight to promote survival thanks to a unique photoprotein.

This novel finding by a team of scientists in Sweden and Spain is published in the online, open access journal PLoS Biology.

"It was long thought that phytoplankton were the on... Read More

No State Microbe For Wisconsin

An update on a piece of news we brought listeners almost two weeks ago: Lactococcus lactis, the little cheese-maker microbe, has failed to become the Wisconsin state microbe. Though it passed the state Assembly, the bill that would make Lactococcus the state microbe was not picked up by the Sena... Read More

Zoologger: The most bizarre life story on Earth

Species: Symbion pandora

Habitat: In the eastern Atlantic Ocean – on the mouthparts of Norway lobsters (also known as Dublin Bay prawns or langoustines)

There's no question that discovering a new species is very cool. But how about discovering a new phylum?

A phylum is a broad division ... Read More

Fossils in seabed on Earth shape search on Mars

Microscopic fossils from the dried-up seabed of the Mediterranean have led space scientists to seek similar evidence of ancient life in the red sands of Mars, where the rover named Opportunity is now exploring.

The scientists said they are impressed by the unexpected discovery of 6-million-ye... Read More

Vaccine fever in Oz: Is the risk real?

This article comes from New Scientist writer Debora MacKenzie, winner of the 2010 ASM Public Communications Award. Read more about the award and her winning entry here. And now on to the article...

Building a Better Biofuel: A New Carbon-Neutral Approach Turns Carbohydrates into Hydrocarbons

When Randy Cortright of the University of Wisconsin found an aromatic fluid floating in his beaker that smelled just like gasoline, he thought he had a problem. After all, the chemical engineer wanted to make fuel from plants for the hydrogen economy that was supposed to boom about now. Instead... Read More

Australia suspends flu shots for children under five.

Dozens of babies and young children, mostly in Western Australia and Queensland, have suffered adverse reactions after having the flu shot, including fevers and convulsions.

And the Queensland Coroner is investigating the death of a two-year-old Brisbane girl, found dead in her cot a day afte... Read More

Hawaii finds 10 rare Salmonella cases linked to frozen ahi tuna, 5 other states also reporting infections

Ten people on Oahu recently became ill with a rare type of salmonella after eating imported raw ahi tuna that was previously frozen, state health officials reported.

The salmonella Paratyphi B cases occurred between Feb. 27 and April 6 in people ranging in age from 5 to 35, said Janice Okubo,... Read More

First genome sequencing of identical twins uncovers little about the origins of disease

The first whole genome sequencing of a pair of identical twins has uncovered little about the origins of disease - even though only one twin has multiple sclerosis (MS).

Identical twins inherit identical genomes but are exposed to different environmental influences. That means they can be eno... Read More

Eukaryotic phytoplankton is now believed to account for almost 50 percent of the ocean’s carbon fixation

"Almost half of the ocean’s carbon fixation is done by eukaryotic phytoplankton, despite the fact that their presence is significantly less than the more abundant blue-green algae known as cyanobacteria.

Cyanobacteria, that grow in vast numbers in the sunlit surface waters of the oceans (the ... Read More

Microbe gold: Arizona State researcher investigates where oil comes from

While most of the dead material in the ocean is recycled by bacteria, lipids are tough, fat-like molecules that "tend to be the least desirable to eat," says Everett Shock, a biogeochemist at Arizona State University. They generally get passed up and fall to the seafloor, where they become burie... Read More

West Nile Virus: The Missing Link

New York City isn't exactly an oasis for wildlife, but its public-health officials are all too familiar with zoonotic diseases, which jump from animals to humans. Ten years before H1N1 erupted among students and killed a principal at an intermediate school in Queens, N.Y., another mysterious ill... Read More

Sight of sick person can trigger immune response

You may cower in disgust when someone sneezes near you, but just seeing that person may make your immune system prepare for battle, a new study suggests.

Research published in the journal Psychological Science found that when people viewed a slide show of photos depicting symptoms of infectio... Read More

Doctors want you to remember polio and diphtheria

Too many American children do not receive recommended childhood vaccines for illnesses such as polio, measles, mumps, diphtheria and pertussis that were once thought to have been eradicated but are making a comeback in some areas. According to data from 2008, almost one-quarter of children ages ... Read More

Another small step for man, but a giant leap for microbial-kind?

Seems the microbes we share spaceship Earth with have figured out the best way to run a low-cost, no frills space program. Makes me wonder if bacteria from Buzz Aldrin (met him one time & shook his hand, so in a sense, I've gotten closer to the Moon than a lotta folks!) or Neil Armstrong are se... Read More
