Liquid DNA behind virus attacks

Viruses can convert their DNA from solid to fluid form, which explains how viruses manage to eject DNA into the cells of their victims. This has been shown in two new studies carried out by Lund University in Sweden.

Both research studies are about the same discovery made for two different vi... Read More

Studies Examine Vaccination Strategies For Prevention, Control of Avian Flu - press release

Two randomized trials in the October 8 issue of JAMA examine new vaccination strategies for the prevention and control of avian influenza, often referred to as “bird flu.” This is a theme issue on infectious disease.

In one study, Mark J. Mulligan, M.D., of the Emory University School of Medi... Read More

Spain Confirms First Ebola Transmission Outside of Africa

Health authorities in Spain have confirmed that a health worker at the Carlos III Hospital in Madrid, Spain has been infected with the Ebola virus. This is the first time anyone has contracted the virus outside of Africa.

The woman, a nurse technician, had worked in the room where two Ebola p... Read More

Giving Chickens Bacteria ... To Keep Them Antibiotic-Free

You know those foods and pills that promise to supply your body with "good bacteria?"

They may or may not make you healthier, but some of these "probiotics" do, in fact, appear to be effective in chickens. Poultry companies are turning to probiotics as an alternative to antibiotics, which hav... Read More

Could Multiple Sclerosis Begin in the Gut?

Multiple sclerosis (MS) is an electrical disorder, or rather one of impaired myelin, a fatty, insulating substance that better allows electric current to bolt down our neurons and release the neurotransmitters that help run our bodies and brains. Researchers have speculated for some time that th... Read More

Where Does Ebola Hide?

The people of Guinea have been locked in a life-and-death struggle with Ebola virus since last December. Nearly 60 percent of Guineans infected with the virus since then have died. To cope with the unprecedented disease, the government went so far as to ban soup made from bats.

Why bats? Bec... Read More

Footage From 1976 Documents Discovery of Ebola Virus

In 1976, a group of health workers took a pair of film cameras to what was then known as Zaire and documented their discovery of a new, deadly virus.

Today we know that virus as Ebola.

A 27-year-old Belgian microbiologist named Peter Piot and his colleagues were the first to scientifically... Read More

‘Programmable’ antibiotic harnesses an enzyme to attack drug-resistant microbes

The multitude of microbes scientists have found populating the human body have good, bad and mostly mysterious implications for our health. But when something goes wrong, we defend ourselves with the undiscriminating brute force of traditional antibiotics, which wipe out everything at once, rega... Read More

Termites evolved complex bioreactors 30 million years ago

Achieving complete breakdown of plant biomass for energy conversion in industrialized bioreactors remains a complex challenge, but new research shows that termite fungus farmers solved this problem more than 30 million years ago. The new insight reveals that the great success of termite farmers ... Read More

My First Radio Interview About Teaching, Research, and Microbial Supremacy...

The great folks at "The People Behind the Science" interviewed me over Skype in late July, and the interview has just been released as a podcast. I discuss my path through science, my thoughts on teaching, research at undergraduate institution, and how to motivate and inspire students to strive... Read More

One Mole

If you multiply the number of bacteria thought exist in one human being, say 1 x 1014 by how many humans there are, about 6.6 x 109, you get close to a familiar number.

And who was Avogadro anyway? Some eponyms fail to do justice to the eponymee. My favorite example is Amerigo Vespucci, whose... Read More

Discovery on how fungi avoid immune responses of plants leads to new generation of fungicides

Plants that come under attack from pathogens have an automatic immune response. Fungi get around this plant immunity by injecting proteins into the host plant cells. These 'effector proteins' enable the fungi to escape the plant's immune system and allow the fungal cells to enter the plant unrec... Read More

New vaccines targeting adults, teens are best chance to eliminate TB by 2050

Targets to eliminate tuberculosis by 2050 are more likely to be met if new vaccines are developed for adults and adolescents instead of for infants, according to new research.

Researchers at the London School of Hygiene & Tropical Medicine and the Stop TB Department at the World Health Organi... Read More

Researchers develop new DNA sequencing method to diagnose tuberculosis

Researchers working in the UK and The Gambia, have developed a new approach to the diagnosis of tuberculosis (TB) that relies on direct sequencing of DNA extracted from sputum (a technique called metagenomics) to detect and characterize the bacteria that cause TB without the need for time-consum...

Whole Genome Sequencing for Outbreak Detection of Salmonella enterica

Salmonella bacteria are a common cause of infectious disease in human and animals. Salmonella is classically divided into species S. bongori and S. enterica – which is in turn further divided into more than 2,500 different serotypes. However, only a limited number of serovars that are responsibl... Read More

Chemists recruit anthrax to deliver cancer drugs

Bacillus anthracis bacteria have very efficient machinery for injecting toxic proteins into cells, leading to the potentially deadly infection known as anthrax. A team of MIT researchers has now hijacked that delivery system for a different purpose: administering cancer drugs.

“Anthrax toxin ... Read More

Research predicts possible 6,800 new Ebola cases this month

New research published in the online journal PLoS Outbreaks predicts new Ebola cases could reach 6,800 in West Africa by the end of the month if new control measures are not enacted.

Arizona State University and Harvard University researchers also discovered through modelling analysis that th... Read More

Breakthrough study discovers six changing faces of ‘global killer’ bacteria

University of Leicester researchers unlock vital new information to improve vaccinations against pneumococcus infection.

Every ten seconds a human being dies from pneumococcus infection, making it the leading cause of serious illness across the globe. New research discovers six unique states ... Read More
