Cells' powerhouses were once energy parasites: Study upends current theories of how mitochondria began

Parasitic bacteria were the first cousins of the mitochondria that power cells in animals and plants -- and first acted as energy parasites in those cells before becoming beneficial, according to a new study.

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

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

'Breath test' shows promise for diagnosing fungal pneumonia

Many different microbes can cause pneumonia, and treatment may be delayed or off target if doctors cannot tell which bug is the culprit. A novel approach—analyzing a patient's breath for key chemical compounds made by the infecting microbe—may help detect invasive aspergillosis, a fungal infecti... Read More

Flu viruses disguised as waste

Viruses cannot multiply without cellular machinery. Although extensive research into how pathogens invade cells has been conducted for a number of viruses, we do not fully understand how the shell of a virus is cracked open during the onset of infection thus releasing the viral genome. An ETH Zu... Read More

Rats and Their Alarming Bugs

If the past few years have taught us anything, it’s that our well-being is intimately linked to the health of animals.

The current Ebola epidemic probably got its start when someone came into contact with an infected animal, perhaps a monkey or a fruit bat. The virus causing Middle East respi... 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

‘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

Shaking up cell biology: Researchers focus in on decades-old mitochondrial mystery

Elvis did it, Michael Jackson did it, and so do the mitochondria in our cells. They shake. While Elvis and Michael shook for decades before loud and appreciative audiences, mitochondrial oscillations have quietly bewildered scientists for more than 40 years.

Now, a team of scientists at Natio... 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

Middle-Aged Adults Were More Susceptible to the Flu Last Year because of a New Viral Mutation

A team of scientists, led by researchers at The Wistar Institute, has identified a possible explanation for why middle-aged adults were hit especially hard by the H1N1 influenza virus during the 2013-2014 influenza season. The findings, published in the Proceedings of the National Academy of Sci... 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

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

Ebola fears: Airline contacts 800 passengers; Belize blocks travel

Take no chances. Leave no stone unturned. Fueled by Ebola fears, these common axioms are driving policy and action -- at times to hefty measures.

This week, a Central American country closed its borders to anyone who has been anywhere near the disease. And an airline scrambled to inform hundr... Read More

Staph ‘gangs’ share nutrients during infection: study

Antibiotic-resistant bacteria can share resources to cause chronic infections, Vanderbilt investigators have discovered. Like the individual members of a gang who might be relatively harmless alone, they turn deadly when they get together with their “friends.”

The findings, reported Oct. 8 in... 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

In Hopes Of Fixing Faulty Genes, One Scientist Starts With The Basics

Whether they admit it or not, many (if not most) scientists secretly hope to get a call in October informing them they've won a Nobel Prize.

But I've talked to a lot of Nobel laureates, and they are unanimous on one point: None of them pursued a research topic with the intention of winning th... Read More

CDC Announces Active Post-Arrival Monitoring for Travelers from Impacted Countries

The Centers for Disease Control and Prevention (CDC) announced that public health authorities will begin active post-arrival monitoring of travelers whose travel originates in Liberia, Sierra Leone, or Guinea. These travelers are now arriving to the United States at one of five airports where e... Read More
