Top Ten Bacteria Working in the Shadows

Childhood was a hazy mix of lace and mud — an age of cookie time, horseplay and the occasional cootie shot. It seems like a far cry from the fettered world of adulthood.

But there were darker forces at play, infiltrators that showed up everywhere we were — near us, on us, in us. Some working ... Read More

Alzheimer's protein may spread through infection

Neurologists have found that the brain plaques associated with Alzheimer's can form when the proteins responsible are injected into the bellies of mice, suggesting that the guilty proteins can get from the body's periphery to wreak havoc in the brain.

A protein called beta-amyloid makes up th... Read More

Haiti says 138 dead in suspected cholera outbreak

An outbreak of severe diarrhea in rural central Haiti has killed at least 135 people and sickened hundreds more who overwhelmed a crowded hospital on Thursday seeking treatment.

Health workers suspected the cause was cholera, but were awaiting tests.

Hundreds of patients lay on blankets i... Read More

The World Is Not Flat: Exploring Cells and Tissues in Three Dimensions

The cells and tissues in our bodies grow, develop and interact in a highly complex, three-dimensional world. Likewise, the various microbial pathogens that invade our bodies and cause infectious disease interact with this complex 3-D tissue milieu. Yet the methods of culturing and studying human...

Tainted celery sickens at least 6 in Texas; 4 die

Texas health officials have shut down a processing plant linked to contaminated celery that sickened at least six people this year, four of whom died, and led to the recall of all of the produce that passed through the plant since January.

SanGar Produce & Processing Co. issued the recall Wed... Read More

Malaria research begins to bite

Scientists at The University of Nottingham and the Wellcome Trust Sanger Institute near Cambridge have pin-pointed the 72 molecular switches that control the three key stages in the life cycle of the malaria parasite and have discovered that over a third of these switches can be disrupted in som...

Coronaviruses cut down interferons. How to get around it?

When confronted with a virus, several cell types in the immune system go about producing interferons, which get the ball rolling, so to speak, and mobilize the innate immune system against the invader. Unfortunately for us, coronaviruses, which include SARS-CoV and many cold viruses, inhibit in... Read More

The origin of complex life – it was all about energy

The 21st century is all about conserving energy. The push towards energy-efficient buildings, vehicles and lifestyles is both fashionable and necessary, but it’s also ironic. Our pattern of ever-increasing energy consumption is deeply rooted in our history, not just since the Industrial Revoluti... Read More

A smarter jab: Big drugs companies see a bright future for vaccines

For decades vaccines were a neglected corner of the drugs business, with old technology, little investment and abysmal profit margins. Many firms sold their vaccine divisions to concentrate on more profitable drugs. This troubled public-health experts because vaccines are a highly effective way ... Read More

Microbes May Consume Far More Oil-Spill Waste Than Earlier Thought

Microbes living at the bottom of the Gulf of Mexico may consume far more of the gaseous waste from the Deepwater Horizon oil spill than previously thought, according to research carried out within 100 miles of the spill site.

A paper on that research, conducted before the Deepwater Horizon ri... Read More

Progress toward treating infections by silencing microbes' 'smart phones'

So disease-causing bacteria in the body finally have multiplied to the point where their numbers are large enough to cause illness. What's next? They get out their "smart phones" and whisper "Let's roll!" That's how an article in ACS' monthly Chemical Reviews describes the substances — "smart ph... Read More

10 infants dead in California whooping cough outbreak

Whooping cough, also known as pertussis, has claimed the 10th victim in California, in what health officials are calling the worst outbreak in 60 years.

Since the beginning of the year, 5,978 confirmed, probable and suspected cases of the disease have been reported in California.

All of th... Read More

A silver bullet for the common cold

Scientists are hailing a breakthrough that could lead to one of medicine's holy grails - a cure for the common cold.

Researchers have found they can attach tiny studs of silver to the surface of harmless bacteria, giving them the ability to destroy viruses.

They have tested the silver-impr... Read More

Bacteria gauge cold with molecular measuring stick

Some bacteria react to the cold by subtly changing the chemistry of their outer wall so that it remains pliable as temperatures drop. Scientists identified a key protein in this response mechanism a few years ago, but the question of how bacteria sense cold in the first place remained a mystery.... Read More

Key difference in how TB bacteria degrade doomed proteins

Scientists at the U.S. Department of Energy's (DOE) Brookhaven National Laboratory and Stony Brook University have discovered a key difference in the way human cells and Mycobacterium tuberculosis bacteria, which cause TB, deliver unwanted proteins — marked with a "kiss of death" sequence — to t...

Improved Antibiotic Coatings: Research Aims to Make Medical Devices Safer by Preventing Biofilms

Bacteria have a natural ability to attach themselves to surfaces, both natural and synthetic. Once attached, they often work cooperatively to form biofilms, thin layers of bacterial colonies that can coat the surface of a medical device and introduce the risk of infection. As a result, orthopedi... Read More
