Las vacunas siempre son más seguras que la propia enfermedad de la que protegen. Algunas enfermedades infecciosas no tienen un tratamiento efectivo y las vacunas son la... Read More

New Tracking Technologies Aim to Prevent Sloppy Handling at U.S. Biolabs

Two months after safety breaches at federal labs first set off a public furor, top health officials are auditioning new checks on worker safety including specialized time-lapse cameras and digital worksheets to track crucial steps such as bacterium inactivation. The goal: to prevent future debac... Read More

Strategic Self-Sabotage? MRSA Inhibits Its Own Growth

Scientists at the University of Western Ontario have uncovered a bacterial mystery. Against all logic, the most predominant strain of methicillin-resistant Staphylococcus aureus (MRSA) in North American produces an enzyme that degrades skin secretions into compounds that are toxic to itself. Th... Read More

"EV-D68 is causing cases of severe respiratory illness ... sometimes resulting in hospitalization, especially among children with asthma," the NYS Department of Health said in a statement... Read More

Fighting Poisons With Bacteria - Going Inside the Rice Microbiome

When Harsh Bais grows rice plants in trays of water in his greenhouse at the University of Delaware, he can easily spot the ones that have been exposed to arsenic: They are stunted, with shorter stems and shrunken, yellow-tinged leaves.

Dr. Bais is working to develop rice plants that take up ... Read More

DIY Droplet Lens, finalist, 2014 Eureka Prize for Innovative Use of Technology

The traditional light microscope is bulky and expensive. Dr Tri Phan and Dr Steve Lee from the Garvan Institute of Medical Research and Australian National University used gravity to manufacture high-performance polymer lenses. These can be seamlessly integrated with 3D printing and mini-LEDs to... Read More

Recruiting bacteria to be technology innovation partners

For most people biofilms conjure up images of slippery stones in a streambed and dirty drains. While there are plenty of "bad" biofilms around – they even cause pesky dental plaque and a host of other more serious medical problems – a team at the Wyss Institute for Biologically Inspired Engineer...

What we are not afraid to say about Ebola virus

In a recent New York Times OpEd entitled What We’re Afraid to Say About Ebola, Michaeal Osterholm wonders whether Ebola virus could go airborne:

You can now get Ebola only through direct contact with bodily fluids. If certain mutations occurred, it would mean that just breathing would put one... Read More

Scientists Call for Investigation of Mysterious Cloud-like Collections in Cells

About 50 years ago, electron microscopy revealed the presence of tiny blob-like structures that form inside cells, move around and disappear. But scientists still don’t know what they do — even though these shifting cloud-like collections of proteins are believed to be crucial to the life of a c... Read More

Motorcycling to Ebola Treatment Could Spread the Infection

Ambulances are scarce in areas of west Africa roiled by the Ebola outbreak, so when ill patients and their families need to go to the clinic they often turn to the next best thing—a motorcycle taxi. An ill passenger will wrap her arms around the driver’s waist and away they will go—sometimes dri... Read More

Scientists develop ‘electronic nose’ for rapid detection of C-diff infection

A fast-sensitive “electronic-nose” for sniffing the highly infectious bacteria C-diff, that causes diarrhoea, temperature and stomach cramps, has been developed by a team at the University of Leicester.

Using a mass spectrometer, the research team has demonstrated that it is possible to ident... Read More

A new way to diagnose malaria

Using magnetic fields, technique can detect parasite’s waste products in infected blood cells.

Over the past several decades, malaria diagnosis has changed very little. After taking a blood sample from a patient, a technician smears the blood across a glass slide, stains it with a special dye... Read More

"Immortal" Cells from Henrietta Lacks Lead to Updated Rules on Genomic Data Sharing

Scientists who work on genomics and are funded by the US National Institutes of Health (NIH) must post their data online so that others can build on the information, the agency has said in an update to its guidelines.

The change, which expands the remit of an earlier data-sharing policy, is ... Read More

Fact or Fiction?: The Ebola Virus Will Go Airborne

Could Ebola go airborne? That’s the fear set off last week by a New York Times op-ed entitled “What We’re Afraid to Say about Ebola” from Michael Osterholm, director of the Center for Infectious Disease Research and Policy at the University of Minnesota. Although clinicians readily agree that th... Read More
