Usually, results from a new study help scientists inch their way toward an answer whether they are battling a health problem or are on the verge of a technological breakthrough. Once in a while, those results give them a giant leap forward.  In a preliminary study in a canine model of Duchenne muscular dystrophy (DMD), University of Missouri scientists showed exactly such a leap using gene therapy to treat muscular dystrophy.

Scientists at The University of Manchester have made a surprising finding after studying how tadpoles re-grow their tails which could have big implications for research into human healing and regeneration.

Apparent stem cell transplant success in mice may hold promise for people with amyotrophic lateral sclerosis (ALS), or Lou Gehrig’s disease.

Most people might see cockroaches as good-for-nothing pests, but this germ-ridden insect could be an indirect source of new antibiotics for humans. Cockroaches host the larvae of a parasitic type of wasp, which spend their formative days eating the bacteria-laden body of the cockroach from the inside out. Researchers have discovered the wasp larva secretes chemicals that sanitize the decidedly unsanitary guts of the cockroach. These germ-killing chemicals could eventually be developed for human uses.

Scientists have used a drug injected into the inner ears of mice deafened by loud noise to induce the regeneration of sound-sensing hair cells and partially restore hearing in the animals, according to a paper published this week (January 9) in Neuron.

Giant pandas may be the source of a new antibiotic, according to scientists at Nanjing Agricultural University in China.

For several years, neurologists at UCLA have been building a case that a link exists between pesticides and Parkinson's disease. To date, paraquat, maneb and ziram — common chemicals sprayed in California's Central Valley and elsewhere — have been tied to increases in the disease, not only among farmworkers but in individuals who simply lived or worked near fields and likely inhaled drifting particles. Now, UCLA researchers have discovered a link - using zebrafish - between Parkinson's and another pesticide, benomyl, whose toxicological effects still linger some 10 years after the chemical was banned by the U.S. Environmental Protection Agency.

A British woman has become one of the first to benefit from pioneering surgery that uses tissue taken from a cow’s heart to rebuild the liver.

The operation brings the possibility of whole donor organs being taken from animals – known as xenotransplantation – ever closer.

Just about everyone has thought about it at least once. What if there were a pill or a shot that could safely burn body fat without any effort?

Besides making some researchers and pharmaceutical companies very rich, it could potentially do a lot for the health of the millions of Americans who are overweight or obese.

A team at Ohio State University's Comprehensive Cancer Center is one step closer to that reality, after its fat-burning shot eliminated 20 percent of belly fat in lab mice over an 80-day period in a recent study.

UT Southwestern Medical Center researchers have pinpointed a molecular mechanism needed to unleash the heart’s ability to regenerate, a critical step toward developing eventual therapies for damage suffered following a heart attack.

Before the advent of refrigeration, Russians had a neat trick for keeping their milk from spoiling. They'd drop a live frog in the milk bucket.

The Russians weren't sure how this amphibian dairy treatment worked, but they were convinced it did.

Since then, researchers have discovered that the goo some frogs secrete through their skin has antibacterial and antifungal properties.

One group of scientists led by a Russian chemist is trying to break down this frog goo at a molecular level. The researchers have found compounds they hope will lead to new medicines.

Their reputations were attacked. Their homes were damaged. Their lives were threatened. But these UCLA scientists refused to back down in the face of assaults by anti-animal-research extremists.

In guinea pigs, inserting a single gene can convert regular heart cells into pacemaker cells that regulate cardiac rhythm, hinting at the possibility of a biological alternative to artificial pacemakers for humans with failing hearts.

A new study by NYU School of Medicine researchers suggests that an existing HIV drug called maraviroc could be a potential therapy for Staphylococcus aureus, a notorious and deadly pathogen linked to hundreds of thousands of hospitalizations each year. Their study is published online this week in Nature.

Rare brain tumors emerging among raccoons in Northern California and Oregon may be linked to a previously unidentified virus discovered by a team of researchers, led by scientists from the University of California, Davis. Their findings, published today in the journal Emerging Infectious Diseases, could lead to a better understanding of how viruses can cause cancer in animals and humans.

New discoveries by University researchers might mean it’s time for your dog to take you to the doctor — not the other way around.

The tip of a single quill on a North American porcupine holds as many as 700 backwards-facing barbs that can lodge into the flesh of any animal that wanders too close. For the first time, scientists have figured out how those barbs work together to make it is so easy for quills to penetrate tissue but so hard to pull them out.

In a government lab where scientists slice open dead animals to study the exotic diseases that killed them, Carol Meteyer peered through a microscope at hundreds of little bats and started to notice something very weird.

The bats had managed to survive the white-nose fungus that had killed millions of other bats hibernating in caves, mostly in the Northeast. But they had succumbed to something else that had left their tiny corpses in tatters, their wings scorched and pocked with holes.

Meteyer finally realized what had happened: In the struggle to fight off the fungus that causes white-nose syndrome, the bats were killed by their own hyperaggressive immune systems.

Yes, maggots are creepy, crawly, and slimy. But that slime is a remarkable healing balm, used by battlefield surgeons for centuries to close wounds. Now, researchers say they've figured out how the fly larvae work their magic: They suppress our immune system.

University of Illinois researchers have developed a model that uses neonatal piglets for studying infant brain development and its effect on learning and memory. To determine if the model is nutrient-sensitive, they have done some research on the effects of iron-deficient diets.
