This algae farm eats highway pollution

Plant-like microorganisms called algae are pretty interesting little creatures - some species form expansive 'algal blooms' that harm the environment, whereas others can be used to produce biofuel and food sources. Some can even infect humans and mess with their brains.

This diverse organism ... Read More

Proof of life: Reevaluating oldest known Archean trace fossil for indications of early biology

In the hunt for early life, geobiologists seek evidence of ancient microbes in the form of trace fossils – geological records of biological activity – embedded in lavas beneath the ocean floor. Filamentous titanite (a calcium titanium silicate mineral) microtextures found in 3.45 billion-year-ol... Read More

How U.S. Hospitals Are Planning To Stop The Deadly MERS Virus

In the past month, Middle East Respiratory syndrome has morphed from a little-known disease in the Arabian Peninsula to a major global health concern, with more than 300 cases in Saudi Arabia in April, 54 of them fatal.

Two cases have been reported in the U.S. as well — one in Indiana and one... Read More

Antibiotics in Blood Can Make Malaria Mosquitoes Mightier

It's well known that antibiotics can disrupt our gut bacteria. But when mosquitoes snack on blood laced with antibiotics, the same can happen to their microbiome. And that depletion of gut bacteria actually increases mosquitoes' susceptibility to the malaria parasite. Meaning they may be more li... Read More

UGA researchers uncover how bacteria helps create clouds

When a clear sunny day turns into clouds, people used it to explain their grave mood without taking into consideration how clouds can affect global warming in the atmosphere. But University of Georgia marine researchers have discovered the process of an anti-greenhouse gas known as DMSP (dimethy... Read More

Researchers create better methods to detect E. coli

Kansas State University diagnosticians are helping the cattle industry save millions of dollars each year by developing earlier and accurate detection of E. coli.

The protective milk shot – How mother’s milk protects piglets from parasite infections

Coccidiosis is a serious disease in new-born piglets. Caused by the parasite Cystoisospora suis, it exclusively infects pigs and often causes severe diarrhoea in suckling piglets. Parasitologists at the Vetmeduni Vienna have developed a new strategy for protecting the piglets: They infected sows... Read More

What Gut Bacteria Might Have To Do With Colorectal Cancer Risk

While genetics likely play a role in some instances of colorectal cancer, a new study in mice suggests gut bacteria could also influence development of intestinal tumors. Researchers from the Icahn School of Medicine at Mount Sinai found that giving antibiotics to mice to disrupt their microbial... Read More

Gonorrhea Infections Start From Exposure To Seminal Fluid

Researchers have come a step closer to understanding how gonorrhea infections are transmitted. When Neisseria gonorrhoeae, the bacteria responsible for gonorrhea, are exposed to seminal plasma, the liquid part of semen containing secretions from the male genital tract, they can more easily move ...

Bacterial Nanowires: Not What We Thought They Were

New videos of morphing bacteria reveal that the strange, distinguishing features of so-called “electric bacteria” aren’t quite what they at first appeared to be.

For the past 10 years, scientists have been fascinated by a type of “electric bacteria” that shoots out long tendrils like electric... Read More

How Ebola Blindsides the Body's Defenses

Researchers often describe the battle between the Ebola virus and the humans it occasionally infects as a race—one that people win only if their immune systems manage to pull ahead before the virus destroys too many of their internal defenses. What they may not know is that the virus is a cheat.... Read More

2,300 tubes containing SARS virus samples missing in France

A major French biomedical research body, the Pasteur Institute, have launched an investigation into the disappearance of some 2,300 test tubes containing samples of the SARS virus. The loss was discovered during an inventory.

The Pasteur Institute filed a so-called 'complaint against X' on Mo... Read More

A WORD on the constraints of influenza virus evolution

Evolution proceeds by selection of mutants that arise by error-prone duplication of nucleic acid genomes. It is believed that mutations that are selected in a gene are dependent on those that have preceded them, an effect known as epistasis. Analysis of a sequence of changes in the influenza vir...

New drugs for bad bugs

Washington University in St Louis chemist Timothy Wencewicz says we’ll stay ahead of antibiotic resistance only if we find drugs with new scaffolds, or core chemical structures. One promising candidate, an antibiotic made by a bacterium than infects plants, caught his attention because it contai... Read More
