Scientists explore the mechanisms of viruses' shells

The genome of viruses is usually enclosed inside a shell called capsid. Capsids have unique mechanic properties: they have to be resistant and at the same time capable of dissolving in order to release the genome into the infected cell. The scientists of the International School for Advanced Stu... Read More

Cilia use different motors for different tasks

Cilia — short, hair-like fibers — are widely present in nature. Single-celled paramecia use one set of cilia for locomotion and another set to sweep nutrients into their oral grooves. Researchers at Brown have discovered that those two cilia sets operate at different speeds when the viscosity of... Read More

Diversity of Antiviral Bacteria Discovered

Wolbachia, a symbiont that resides naturally up to 70% of all insect species, are probably the most prevalent infectious bacteria on Earth. In 2008 Luis Teixeira, now a principal investigator at the Instituto Gulbenkian de Ciência, and other scientists have discovered that Wolbachia can protect ... Read More

The Way You’re Born Can Mess With the Microbes You Need to Survive

Throughout the animal kingdom, mothers transfer microbes to their young while giving birth. Different species of tadpoles acquire specific skin bacteria from mother frogs even though they all live in the same pond with the same bacterial background. Emerging chicken eggs get inoculated with micr... Read More

A Glass of Milk After Eating Sugary Cereals May Prevent Cavities

Washing down sugary breakfast cereal with milk after eating reduces plaque acid levels and may prevent damage to tooth enamel that leads to cavities, according to new research at the University of Illinois at Chicago College of Dentistry. Read More

Hop leaves — discarded in beer brewing — have substances that could fight dental diseases

Beer drinkers know that hops are what gives the drink its bitterness and aroma. Recently, scientists reported that the part of hops that isn’t used for making beer contains healthful antioxidants and could be used to battle cavities and gum disease. In a new study in ACS’ Journal of Agricultural... Read More

India scrambles to save tigers from deadly virus

India is scrambling to protect its beleaguered tiger population after several big cats tested positive for a virus common among dogs but deadly to other carnivores, experts said.

In the last year, canine distemper virus has killed at least four tigers and several other animals across northern... Read More

Source of Justian Plague Sequenced?

In a fascinating story that was presented on NPR by Nell Greenfieldboyce we learn that the source of the Justian Plague (541-543AD) was recently identified by sequencing blood extracted from the dental pulp of the teeth associated with two skeletons recovered from Munich. For many years it was... Read More

On Teaching

A graduate student came to my office recently to say that she was increasingly bothered by anxiety and the ‘terror’ of having to speak at laboratory meetings. She had also learned a month ago that she was expected to lecture to a class organized by her mentor. The thought of having to lecture to... Read More

Scientists Figure Out How Microbes Make Wine Good

Yeast aren’t the only microbes that help turn boring grapes into the delicious, seductive, complex, confusing, subtle, and totally splendiferous tonic known as wine. In addition to those well-known fermenters, a type of bacteria called Oenococcus oeni (for reasons that will be obvious to oenophi... Read More

New Wearable Device Could Protect Against HIV and Pregnancy

If a sexually active woman wants to protect herself from unwanted pregnancy and HIV using a single method, she has always been limited to condoms. A new paper, released today in PLOS ONE details a first-of-its-kind device that provides an alternative.

Uncovering the secret world of the Plastisphere

Scientists are revealing how microbes living on floating pieces of plastic marine debris affect the ocean ecosystem, and the potential harm they pose to invertebrates, humans and other animals. New research being presented here today delves deeper into the largely unexplored world of the “Plasti... Read More

Oldest Living Things In the World (video)

For nearly a decade, Brooklyn-based artist, photographer, and Guggenheim Fellow Rachel Sussman has been traveling the globe to discover and document its oldest organisms — living things over 2,000 years of age. Her breathtaking photographs and illuminating essays are now collected in The Oldest ... Read More

Tiny Algae Responsible for Mysterious Fossil Whale Graveyard?

Ever since a highway construction crew in Chile uncovered a fossil graveyard of some 40 prehistoric whales in 2010, with skeletons dating back more than five million years, scientists have wondered why so many giant animals died in one place. This week, a team of them proposed an answer: The hug... Read More

UNC researchers discover new target for dengue virus vaccine

Using an experimental technique new to the dengue field, the labs of Ralph Baric, PhD, and Aravinda de Silva, PhD, showed that a molecular hinge where two regions of a protein connect is where natural human antibodies attach to dengue 3 to disable it. The finding, published in the Proceedings of... Read More

Adhering To The 'Replicon Model' The Sloppy Way

Sixty years ago Jacob, Brenner and Cuzin devised their 'Replicon Model', inspiring and useful guideline for replication research ever since. According to the model, a 'Replicon' is a genetic element replicated from a single 'Replicator'—replication origin, in modern terms—and replication is trig... Read More

How do they make it work? Genomic Revelations on a Bacterial Consortium

Do you ever look at a couple and wonder… ‘Why are they together? What does X see in Y. I just don’t get it. Is X in it only for the money’? Who doesn’t at times ponder about such matters? There’s practically an entire economy based on it. However, you didn’t find this article while waiting to ... Read More

Warmer temperatures push malaria to higher elevations

Researchers have debated for more than two decades the likely impacts, if any, of global warming on the worldwide incidence of malaria, a mosquito-borne disease that infects more than 300 million people each year. University of Michigan ecologists and their colleagues are reporting the first har... Read More

Researchers find that going with the flow makes bacteria stick

In a surprising new finding, researchers have discovered that bacterial movement is impeded in flowing water, enhancing the likelihood that the microbes will attach to surfaces. The new work could have implications for the study of marine ecosystems, and for our understanding of how infections t... Read More
