Certain bacteria can build such complex membrane structures that, in terms of complexity and dynamics, look like eukaryotes, i.e., organisms with a distinct membrane-bound nucleus. Scientists from Heidelberg University and the European Molecular Biology Laboratory (EMBL) made this discovery empl... Read More
Endogenous retroviruses (ERVs) are viruses that at some point in the past inserted themselves into the nuclear genome of a host's germ cell. Once integrated in a germ cell the virus would be passed on from one generation to the next and the endogenous retroviral genome would therefore be inherit... Read More
The gut bacteria in horses are being researched at the University of Pennsylvania, in a series of projects that scientists hope will ultimately benefit animal and human health.
Researchers at the university’s School of Veterinary Medicine are leading five pilot projects as part of the wider i... Read More
Spot the next plague before it arrives. Predict the next swine flu outbreak before it makes headlines. Even detect a biological weapon before it's launched.
These are the goals of an ambitious initiative, launched Thursday, to build a worldwide surveillance system for infectious diseases.

An international team of researchers including scientists from the University of York have discovered a ‘microbial Pompeii’ preserved on the teeth of skeletons around 1,000 years old.
The key to the discovery is the dental calculus (plaque) which preserves bacteria and microscopic particles o... Read More
Researchers at the University of Melbourne have discovered that some Indigenous groups will be more susceptible to the effects of the new strain of influenza (H7N9) currently found in China.
Research indicated that some Indigenous people such as in Alaska and Australia displayed limited immun... Read More
Researchers at Sandia National Laboratories are developing a medical instrument that will be able to quickly detect a suite of biothreat agents, including anthrax, ricin, botulinum, shiga and SEB toxin.
The device, once developed, approved by the Food and Drug Administration and commercialize... Read More
Three new cases of infection with the Middle East respiratory syndrome coronavirus (MERS-CoV) -- including two more healthcare workers -- have been reported in Saudi Arabia.
The two healthcare workers, both women, have mild symptoms after exposure to patients who had laboratory-confirmed MERS... Read More
The international medical humanitarian organization Doctors Without Borders/Médecins Sans Frontières (MSF) has started a rabies intervention in the east of the Democratic Republic of Congo (DRC) after an alarming number of people were bitten by rabid dogs. With ten deaths already reported, the e... Read More
In what seems like a plot straight out of a low-budget science-fiction film, scientists have revived a giant virus that was buried in Siberian ice for 30,000 years — and it is still infectious. Its targets, fortunately, are amoebae, but the researchers suggest that as Earth's ice melts, this cou... Read More
Vaccines are just for kids, right? Not any more. U.S. health officials now recommend at least a half dozen vaccines for adults, to prevent pneumococcus virus, hepatitis, shingles and other ailments. And although the portion of adults who get these vaccinations rises slightly each year, the rates... Read More
Wine grapes present a unique biogeography model, wherein microbial biodiversity patterns across viticultural zones not only answer questions of dispersal and community maintenance, they are also an inherent component of the quality, consumer acceptance, and economic appreciation of a culturally ...

Last year, I wrote about finding the carcasses of dead loons and cormorants on the shores of a Northern Lake Michigan beach. Now officials in New York are reporting similar waterbird deaths from Type E botulism on Lake Ontario.
Sadly, finding type E botulism in waterbirds is becoming an “annu... Read More
Glasgow’s army of knitters are being asked to craft a friend for the bug, who has been snapped throughout the city looking for other microbes to play with. The smiling bacteria has been pictured on Buchanan Street, by the Science Centre and outside Central Station. The microbe is part of a world... Read More
The lab was a crime scene; dead and dying cells were everywhere—but did they commit mass suicide or were they murdered? The burly young post doc who discovered the corpses sat in the corner sobbing softly, his PI by his side. She was trying in vain to comfort her most promising young scientist i... Read More
Tiny electrical wires protrude from some bacteria and contribute to rock and dirt formation. Researchers studying the protein that makes up one such wire have determined the protein's structure. The finding is important to such diverse fields as producing energy, recycling Earth's carbon and min... Read More
We continue our semi-annual ritual and post this quick tour of our blog posts published since December, 2012.
Our new section dealing with “pictures that made a difference but may be nearly forgotten by now” seems to be off to a good start. Please send us suggestions of... Read More
In an advance for HIV vaccine research, a scientific team has discovered how the immune system makes a powerful antibody that blocks HIV infection of cells by targeting a site on the virus called V1V2. Many researchers believe that if a vaccine could elicit potent antibodies to a specific conse... Read More
A new device from Macquarie University can manipulate objects as small as 50 nanometers wide — about a thousandth of the width of a human hair and small enough to allow direct manipulation of a single viral capsule.

Going barefoot in parts of Africa, Asia, and South America contributes to hookworm infections, which afflict an estimated 700 million of the world’s poor. The parasitic worm lives in the soil and enters the body through the feet. By feeding on victims’ blood, the worms cause anemia and, in child... Read More
