Researchers at Washington University School of Medicine in St. Louis believe they've uncovered a vital step in developing a vaginal gel that may prevent the spread of HIV, which causes AIDS.
Nanoparticles carrying a toxin found in bee venom can destroy human immunodeficiency virus (HIV), while leaving surrounding cells unharmed.

Most people think that veterinarians are doctors who treat cats and dogs, provide compassionate, expert care but also charge amply for their services. This narrow view means that a vet's work is underestimated and, often, not respected. In reality their role is substantially broader and yet their leadership potential is generally overlooked.
While many vets are caregivers for our domestic animals -- and it's very important work -- a larger mission is to focus on minimizing the transmission of infectious disease and help tackle world hunger issues.

Alligator blood is showing to be a potent antibiotic in lab testing at McNeese State University. These keepers of the bayou are known for their tenacity, but behind the alligator's piercing eyes and sharp teeth is an immune system that is as ferocious as the primitive creature.

Scientists may be better able to study how heavy drinking damages the liver using a new mouse model of alcohol drinking and disease developed by researchers from the National Institute on Alcohol Abuse and Alcoholism (NIAAA), part of the National Institutes of Health. The model incorporates chronic and binge drinking patterns to more closely approximate alcoholic liver disease in humans than any existing method. A report of the new model appears in the March issue of the journal Nature Protocols.

New research from the Oklahoma Medical Research Foundation shows that eating a high-fat diet produces a similar effect to starvation in cells and could be key in understanding why cells “flip the switch” to burn fat instead of sugar in the early stages of diabetes.

Mollie Heinz had two surgeries to remove parts of her bowel due to flareups of Crohn’s disease.
Even so, the 37-year-old mother from Maryland Heights isn’t so hot about the idea of ingesting the eggs of pig whipworms to treat the condition. The eggs, it seems, might be the latest icky way to treat a bacterial balance gone bad in the human gut.

For years, researchers have worked to decode the mysteries of how dogs that race 1,000 miles perform so well -- and how to help them. Research on the physical stamina and the high-performance metabolism of Iditarod dogs has led to changes in the way the animals are conditioned, cared for, fed and rested. Now, from the wintery reaches of the northern United States, the iconic dogs of Alaska's Last Great Race are helping keep American soldiers safe in the deserts of Afghanistan.

Stanford scientists have demonstrated a technique for observing hundreds of neurons firing in the brain of a live mouse, in real time, and have linked that activity to long-term information storage. The unprecedented work could provide a useful tool for studying new therapies for neurodegenerative diseases such as Alzheimer's.

When it comes to hanging on tight, the lowly mussel has few rivals in nature. Researchers have sought the secrets behind the bivalve's steadfast grip on wet, slippery rock. Now, reporting here today at the annual meeting of AAAS (which publishes ScienceNOW), a researcher said he has used the mollusk’s tricks to develop medical applications. These include a biocompatible glue that could one day seal fetal membranes, allowing prenatal surgeons to repair birth defects without triggering dangerous premature labor.

Gene therapy has successfully banished type 1 diabetes in dogs, the first time this treatment has worked to treat the disease in a large animal, according to a study published online in the journal Diabetes earlier this month (February 1).

What would happen if all clothes were made to fit only one person, or at
most, that person and his or her identical twin? Whoever it was, this
one person wouldn’t represent all people. I hope this is an obvious
statement—we all have differences in every measurement possible, and
certainly no manufacturer would make a line of clothing tailored only to
one person’s size.
But imagine taking this person and testing a new drug in her. Or him. Would you consider the drug fully tested for all people? No, it’s common sense that different people would respond differently, a concept borne out by the presence of side effects of varying severity for every significant pharmaceutical. But historically, that’s how most drugs have been selected for development until very late in the process. And that’s just one reason why it’s important to discuss the full story behind the recent New York Times article “Mice Fall Short as Test Subjects for Humans’ Deadly Ills.”

It’s been three months since Hurricane Sandy barreled along the East Coast, plunging the majority of Manhattan and surrounding boroughs into darkness, and displacing hundreds of people from their homes. As neighborhoods continue to rebuild, and in honor of the three-month anniversary, President Obama recently signed the much-anticipated Sandy Relief Bill for $50.5 billion.
One group awaiting some of that recovery funding are scientists and researchers from New York University (NYU), who lost years of research in cancer and neuroscience when the storm knocked out the power supporting their freezers, and water flooded their animal facilities, drowning their mice.

Mice carrying human disease genes have proved valuable for learning what goes awry in people. Now, researchers have tapped the rodents to understand human evolution. Mice with a human version of a gene called EDAR have more sweat glands than normal, providing clues to how East Asians adapted to a humid environment 30,000 years ago.

Geneticists led by University of Utah Nobel Prize Laureate Mario R. Capecchi, Ph.D., have engineered mice that develop clear cell sarcoma (CCS), a significant step in better understanding how this rare and deadly soft tissue cancer arises.

A team led by scientists at The Scripps Research Institute (TSRI) has identified specific cellular events that appear key to lupus, a debilitating autoimmune disease that afflicts tens of millions of people worldwide. The findings suggest that blocking this pathway in lupus-triggering cells could be a potent weapon against the disease.

A Midwestern company has returned to its Hub roots to try to adapt drugs made for humans into treatments for cats and dogs.

A discovery about the aging process in mice might one day help efforts to develop treatments for age-related diseases in humans, researchers report.

Zebrafish, the staple of genetic research, may hold the answer to repairing damaged retinas and returning eye-sight to people. University of Alberta researchers discovered that a zebrafish's stem cells can selectively regenerate damaged photoreceptor cells.

The most sensitive patch of mammalian skin known to us isn't human but on the star-shaped tip of the star-nosed mole's snout. Researchers studying this organ have found that the star has a higher proportion of touch-sensitive nerve endings than pain receptors, according to a study published Jan. 30 in the open access journal PLOS ONE by Diana Bautista and colleagues from the University of California, Berkeley and Vanderbilt University.

Jasper, a 7-year-old rescue dog from San Jose, has a personality that endears him to everyone -- even to cats. He also has lymphoma, a cancer that sprouts from the body's defense system and is similar to non-Hodgkin lymphoma in people.
Right now, Jasper's treatment plan is based on laboratory tests, ultrasounds and the expertise of his veterinarian, Linda Fineman, a cancer specialist at the SAGE center in Campbell. In the future, however, tests on Jasper's DNA could determine the best medications for him and show how long they'll work, according to scientists who study the DNA of dogs. And those researchers are increasingly discovering that cancer and other diseases are caused by the same genetic mutations in pooches and people. So as scientists develop new therapies for canine cancers, they're also finding more effective methods to treat similar problems in humans.
