How rare 'words' in bacterial genes boost protein production. Scientists routinely seek to reprogram bacteria to produce proteins for drugs, biofuels and more, but they have struggled to get those bugs to follow orders. But a hidden feature of the genetic code, it turns out, could get bugs with... Read More
A brighter, better, longer-lasting dental implant may soon be on its way to your dentist's office. Dental implants are posts, usually made of titanium, that are surgically placed into the jawbone and topped with artificial teeth. More than dentures or bridges, implants mimic the look and feel of... Read More
Purdue University researchers successfully eliminated the native infection preferences of a Sindbis virus engineered to target and kill cancer cells, a milestone in the manipulation of this promising viral vector.
"This virus had been known to be a good vector for delivering therapeutic cargo... Read More
Researchers are gathering this week to debate the most humane methods of dispatching lab animals, which are primarily rodents. Killing research animals is one of the most unpleasant tasks in science, and it is imperative to do it as humanely as possible. But researchers who study animal welfare... Read More
Depending upon whom you ask, the smell that has plagued La Jolla Cove has been “putrid,” “noxious” or “like the East River used to smell,” for quite a while. Nose-pinching is commonplace.
But now, the stench of bird guano emanating from the cliffs in the seaside neighborhood has become, off... Read More
Medical investigators for the first time have confirmed the MERS coronavirus in a camel, one belonging to a Saudi man also ill with the new virus, providing a critical clue into the virus's animal hosts and transmission, a top Saudi health official and an international disease expert said on Mon...

JOSEPH LEIDY – 1823-1891
Joseph Leidy (1823-1891), naturalist, comparative anatomist, paleontologist, and microscopist, was dubbed by his biographer as “the last man who knew everything.” Leidy also made substantial contributions to the field of protozoology and is considered America’s first... Read More
Endangered Amur tigers (also called Siberian tigers) face challenges from poaching, decimation of their prey base, and habitat fragmentation, but a disease from domestic dogs may be the straw that broke the tiger's back, according to the authors of a study in mBio this week. A team of scientists... Read More
Since its appearance in the U.S. seven years ago, white-nose syndrome has decimated bat populations across eastern North America. Scientists say they've determined the culprit—a soil-dwelling fungus called Pseudogymnoascus destructans—and now they're investigating novel ways to stop it, includin... Read More
In a study published in Nature, the team from University College London and the Medical Research Council Laboratory of Molecular Biology explains how HIV uses molecules inside host cells in an infected person to avoid alerting the body’s innate immune system (IIS) – cells and mechanisms that for...

The bottlenose dolphins are migrating south. So officials in New Jersey thought that they had seen the last of the strandings - animals washing onto beaches, dead or dying - in what has become the largest Atlantic Coast die-off of dolphins in memory.
But on Monday, the body of another dolphin... Read More
Researchers report the detection of a strain of Seoul hantavirus (SEOV) in pet rats in England and Wales. The discovery followed an investigation of a case of haemorrhagic fever with renal syndrome in Wales. Hantavirus RNA was detected via real-time reverse transcription-polymerase chain reactio...

Improvement in reforestation and agriculture is possible thanks to the work of scientists in the Center of Research and Advanced Studies (Cinvestav) who use different strains of fungi and bacteria to promote development and health in trees, which have enabled them to accelerate growth of differe...

Hollywood has amplified the idea of a zombie apocalypse for a long time, and the stories have grown increasingly popular in pop culture, particularly due to TV shows like ‘The Walking Dead‘ and movies like ‘World War Z.’
However, when you take science fiction out of the equation and add real-... Read More
Cells that allow helpful bacteria to safely colonize the intestines of newborn infants also suppress their immune systems to make them more vulnerable to infections, according to new research in Nature.
Published online Nov. 6, the study could prompt a major shift in how medicine views the th... Read More
After taking an in-depth look at the basic biology of a fungus that is decimating bat colonies as it spreads across the U.S., researchers report that they can find little that might stop the organism from spreading further and persisting indefinitely in bat caves.
Their report appears in the ... Read More
Insects are repelled by N,N-diethyl-m-toluamide, also known as DEET. But exactly which olfactory receptors insects use to sense DEET has eluded scientists for long.
Now researchers at the University of California, Riverside have identified these DEET-detecting olfactory receptors that cause ... Read More
Purple bacteria contain pigments that allow them to use sunlight as their source of energy, hence their color. Small as they are, these microbes can teach us a lot about life on Earth, because they have been around longer than most other organisms on the planet. University of Miami (UM) physicis... Read More
Amidst the outrage, puzzlement and theories caused by the finding of genetically-modified wheat in an Oregon field, USDA is considering whether to commercialize another dinnertime staple–the potato.
Last month, Idaho-based J.M. Simplot asked the Agriculture Department to grant a deregulated s... Read More
In my newest blog post, I discuss how taking a "beginner's mind" approach leads to creativity, real learning, and enthusiasm. I tie together Suzuki's "Beginner's Mind" concept with Elio Schaechter's "Talmudic Questions," and give an example from one of my first seminars. Read More
