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
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
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
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
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
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

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
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
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
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
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
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
The Ebola virus disease epidemic already devastating swaths of West Africa will likely get far worse in the coming weeks and months unless international commitments are significantly and immediately increased, new research led by Yale researchers predicts.
The findings are published in the Oc... Read More
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
Many double-stranded DNA viruses infect cells by ejecting their genetic information into a host cell. But how does the usually rigid DNA packaged inside a virus' shell flow from the virus to the cell?
In two separate studies, Carnegie Mellon University biophysicist Alex Evilevitch has shown t... Read More
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
The Epstein–Barr virus and its relatives in the herpesvirus family are known for their longevity. They persist in host tissues for years, causing diseases like mononucleosis, Kaposi's sarcoma and herpes, and are notoriously difficult to kill. University of California, Los Angeles, biophysicist Z... Read More
Cornell researchers have uncovered details of how the deadly Middle East respiratory syndrome coronavirus (MERS-CoV) enters host cells, findings that help explain how it can infect many cell types – a hallmark of viral pathogenicity. The results also offer possible new avenues for treatment.

From joint replacements to cardiac implants and dialysis machines, medical devices enhance or save lives on a daily basis. However, any device implanted in the body or in contact with flowing blood faces two critical challenges that can threaten the life of the patient the device is meant to hel... Read More
