Can the brain repair itself from within? Duke researchers, who have discovered a new neuron in the brain of adult mice that is capable of telling stem cells to make more new neurons, are suggesting it’s possible!

A genetic mutation causes mice to over-groom to the point of near baldness, except for an obsessively touched-up strip of hair between the ears. Such were the findings of an international team of neuroscientists at NYU Langone Medical Center, who intentionally bred the mice hoping to uncover clues about autism.

Dogs are undergoing a new search-and-rescue mission - detecting cancer! Having extremely sensitive noses, a research study has shown that dogs are able to accurately detect the chemicals emitted from a tumor by a tissue sample. This can lead to early detection that can save countless lives!

Researchers at the University of Kansas Medical Center are hoping that a new project can bring two new cancer drugs to market — one for humans and another for their furry friends.

Zoo-goers may marvel at their bare skin and wrinkles, but scientists are more interested in the long lives of the pale, toothy and nearly hairless rodents known as naked mole rats. With lifespans of up to 31 years, naked mole rats live decades longer than would be expected based on their size. By comparison, mice live at most four years.

There have always been limitations to experiments with mice, but new technology, which allows scientists to replace mouse genes with human genes, could clear the way for new ground to be broken.

Deadly Australian snake venom is being used in an innovative new product to fast-track blood test results for seriously ill patients.

With funding from the National Institutes of Health's National Institute of Aging, Cornell scientists are joining interdisciplinary collaborators from across the country to form the Canine Longevity Consortium – the first research network to study canine aging. It will lay the groundwork for a nationwide Canine Longitudinal Aging Study (CLAS), using dogs as a powerful new model system that researchers can study to find how genetic and environmental factors influence aging and what interventions might mitigate age-related diseases.

Schizophrenia is a severe disease for which there is still no effective medical treatment. In an attempt to understand exactly what happens in the brain of schizophrenic people, researchers from the Univ. of Southern Denmark have analyzed proteins in the brains of rats that have been given hallucinogenic drugs. This may pave the way for new and better medicines.

Flu epidemics cause up to half a million deaths worldwide each year, and emerging strains continually threaten to spread to humans and cause even deadlier pandemics. A study by a McGill University professor reveals that a drug that inhibits a molecule called prostaglandin E2 (PGE2) increases survival rates in mice infected with a lethal dose of the H1N1 flu virus. The findings pave the way for an urgently needed therapy that is highly effective against the flu virus and potentially other viral infections.

Working with animal models, Duke University researchers and other scientists are making strides in growing muscle in the lab that not only repairs itself but exhibits strength similar to that of normal muscle.

Using lab-grown muscle could one day help people with certain muscle injuries, including accident victims with big gashes that lead to significant scar tissue. Engineering muscle that works like natural tissue could also accelerate the testing of new drugs: Scientists could use this tissue in place of animals.

Using a new gene-editing system based on bacterial proteins, MIT researchers have cured mice of a rare liver disorder caused by a single genetic mutation.

A new drug extracted from snail venom could provide a breakthrough in treating severe chronic pain without the risk of addiction and dangerous side effects, researchers have found. The venom - considered 100 times stronger than morphine - could lead to the development of a new class of oral drugs used to relieve nerve pain associated with injury, cancer, AIDS and other diseases.

While scientists know that a superfamily of genes inside olfactory receptors is responsible for our sense of smell – we still don’t know the mechanism behind the interpretation of odor molecules into a particular smell. A new study published in the journal Molecular Biology and Evolution has found a distinct gene pattern in the olfactory receptors of fruit-eating bats – potentially shedding some light on the mechanism behind our own sense of smell.

New research using fruit flies with Alzheimer’s protein finds that the disease doesn’t stop the biological clock ticking, but detaches it from the sleep-wake cycle that it usually regulates. Findings could lead to more effective ways to improve sleep patterns in those with Alzheimer’s.

Cancer of the pancreas is usually not detected until it’s too late to cure. But precursor lesions that form in the pancreas and its ducts can signal the disease before it strikes, and when caught early enough, they can be prevented from progressing to become cancer.

A new study reports two breakthroughs in understanding those lesions and their role in pancreatic cancer: the development of the first mouse model that simulates a precursor lesion called intraductal papillary mucinous neoplasia (IPMN), and the identification of an enzyme, Brg1, that appears to help cause the formation of IPMN lesions while also suppressing another precursor lesion.

Colorado State University researchers are finding new ways to treat cancers in humans and pets, but they are doing it with a specimen not of those species: mice.
