Babies' Weak Immune Systems Let In "Good" Bacteria

As any new parent knows, infants are notoriously susceptible to bacterial infections. A study now suggests that the body engineers this vulnerability deliberately, allowing beneficial microbes to colonize the baby’s gut, skin, mouth and lungs. Learning to manipulate this system could lead to tre... Read More

Parvo Trial Shows Promising Results In Effort To Combat Puppy Virus

A North Dakota company that discovered an antibody technology while trying to cure flocks of dying geese is using its research for a more warm and fuzzy purpose: saving puppies.

Early tests performed on about 50 puppies in seven U.S. states for Grand Forks-based Avianax have resulted in a 90 ... Read More

Tube morphology

Three organisms inoculated in TSB to look at tube morphology. From left to right:
Staphylococcus aureus: flocculent growth/turbid, growth throughout the tube.
Mycobacterium smegmatis: pellicle, growth at the top of the tube. M. smegmatis tends to stick to the tube and grow up the side.

Scientists create accurate predictor of the next year’s flu virus

Influenza viruses evolve rapidly, making it hard to develop protective vaccines against them. Despite a great deal of effort, scientists have found it difficult to forecast which way the virus’ evolution would take it. Now, thanks to improvements in our ability to study viruses and a new mathema... Read More

Paint a virus to death

An Auckland scientist has invented molecules that can attach themselves to any surface in a few minutes and modify every type of cell or virus. The potential for the technology is huge - from attacking cancer cells to protecting newborn babies. Read More

When Will We Have a Vaccine for Ebola Virus?

The latest outbreak of Ebola virus in west Africa is the worst ever—as of Monday, it had infected more than 1,200 people and claimed at least 672 victims since this spring. Guinea, Liberia and Sierra Leone all have confirmed cases. An official at Doctors Without Borders has declared the outbreak... Read More

Neanderthal Viruses Found in Modern Humans

Ancient viruses from Neanderthals have been found in modern human DNA by researchers at Oxford University and Plymouth University.

The researchers compared genetic data from fossils of Neanderthals and another group of ancient human ancestors called Denisovans to data from modern-day cancer p... Read More

Photonic tweezers can pick up a single virus with light

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.

Freshman Biology Creative Projects!

I have found that students become involved, energized, and enthusiastic when I give them opportunities to explore topics in my classes using their own creative approaches and interests. So this semester, in my Biology 111 course at the University of Puget Sound, I found that students explored f... Read More

NASA To Test Microgravity’s Effect On Bacteria, Antibiotics

NASA’s Antibiotic Effectiveness in Space (AES-1) investigation is launching in January and it will be offering scientists more insight into how bacteria behave in microgravity.

Bacteria are considered the most successful life forms, and they are hard to run from, even in space. In a micrograv... Read More

Florida Bill Would Combat Superbug Threat

A bill to track drug-resistant infections has been introduced in Florida, inspired in part by FRONTLINE’s Hunting the Nightmare Bacteria.

The bill, sponsored by Rep. Janet Adkins, a Republican, requires the state health department to maintain an online record of the type and location of any a... Read More

Bio-artist colors textiles with deadly bacteria and antibiotics

Would you cuddle up with a quilt stained with MRSA? Artist Anna Dumitriu challenges the relationship between humans and bacteria by staining textiles with superbugs.

As part of her artist's residency on the UK Clinical Research Consortium Project “Modernising Medical Microbiology” at the Univ... Read More

The bacteria in breast milk

Bacteria are found in large numbers all over the human body where there is a channel to the outside world, for example in the gut, lungs, and surface of the skin. I’ve always thought that actually inside the human body was a bacteria-free environment unless an infection was raging so I was very ... Read More

Smells Like … An Armpit Infection?

One man's irrepressible body odor was the result of a bacterial infection of his armpit hair, according to a new report of the case.

The 40-year-old man told his doctors he'd had armpit odor and "dirty" armpit hair for the last four years.

There was a "creamy yellow" substance on the man's... Read More

Better batteries through biology?

MIT researchers find a way to boost lithium-air battery performance, with the help of modified viruses.

Lithium-air batteries have become a hot research area in recent years: They hold the promise of drastically increasing power per battery weight, which could lead, for example, to electric c... Read More

Gut Ecosystem Restoration via Fecal Transplantation

Relapsing clostridium difficile infection (CDI) is a disease that patients face after being medicated with antibiotics that damage their microbiota. A recent and effective treatment to eradicate this condition is known as “fecal material transplant” (FMT), where a healthy human will donate a sam... Read More
