In research against superbugs, mice may be passé, but frogs are all the rage. University of Melbourne scientists are looking at synthetic antimicrobial skin secretions of the Australian greened-eyed and growling grass frogs to look for new ways to beat back antibiotic-resistant bacteria.

Researchers at the University of Colorado have found a cure for Type 1 Diabetes– in mice. The research team will determine if it could prevent the disease in humans as well.

Is research with animals no longer necessary, as the activists believe? Can we rely exclusively on other methods to treat heart and lung disease, stroke, cancer, Alzheimer’s and Parkinson’s disease, and other conditions that threaten the lives of thousands of British Columbians? Should we simply make a quantum leap from computer models to human subjects? The truth is that research with animals is complex, expensive, and ethically challenging — but it is absolutely necessary to save lives and treat diseases. Computer models, cell cultures, and tissue samples are not an acceptable substitute for a complex living organism. We fundamentally disagree with those who believe we should experiment directly on human beings before determining whether potential treatments are effective in animals.

A newly developed, genetically modified pig may hold the keys to the development of improved treatments and possibly even a cure for retinitis pigmentosa (RP), the most common inherited retinal disease in the United States. The pig model was developed by researchers in the University of Louisville Department of Ophthalmology & Visual Sciences and at the National Swine Resource and Research Center at the University of Missouri.

Many medical studies involve laboratory animals, but when it comes to research on asthma, no creature provides a better model than the horse. Veterinarians at Virginia Tech believe our equine friends might help humans who struggle to breathe.

New research offers potential insight into the connection between cancer, obesity and longevity in humans by showing that genetically modified mice live longer, skinnier and almost cancer-free lives.

Dr. Zheng Xiaoxiang of the Brain-Computer Interface Research Team says that she has trained a monkey to control a robotic hand with its brain. What's especially interesting about this story is that scientists claim to have achieved a new level of fine motor control, allowing the monkey to articulate individual fingers, instead of using a "whole hand" approach, as we've seen previously. This is a vast improvement on previous models since the neuronal connections required for fine motor control are significantly more complicated.Just think about the improvements to quality of life that this kind of research can offer. Soon, it will no longer be the stuff of science fiction that people will wear robotic prosthetics

Scientists at the Sanford-Burnham Medical Research Institute have developed a new mouse model for studying a childhood brain cancer called medulloblastoma. The animal model mimics the deadliest of four subtypes of human medulloblastoma, a tumor that is triggered by elevated levels of a gene known as Myc.

After 10 years in development, a novel mouse population proves its mettle in complex trait research.

 New research in mice suggests that Alzheimer's disease triggers a protein that contributes to the breakdown of the brain's memory.

The quest for treatments for motor neurone disease, spinal cord injury and strokes could be helped by new research that shows how key cells are produced. Scientists at the University of Edinburgh have been able to manipulate the production of motor neurones – which control all muscle activity – in zebrafish.

Drug developers have long dreamed of discovering a tonic to trip up the aging process, hunting for genetic clues and compounds that could provide a fountain of youth. U.K. researchers say they have found a recipe for immortality--in flatworms. But the worm study might shine a light on ways to prolong human life too, investigators said.

A male contraceptive pill tested in rats keeps sperm from developing in the testes while still allowing for a robust libido, researchers at the University of Kansas School of Medicine have discovered.

This may not be news about embryonic stem cells, but it could end up being just as controversial. Researchers at Massachusetts General Hospital and elsewhere have figured out how to harvest stem cells from a woman's ovaries and encourage them to morph into functional eggs, using human cells in a lab dish and separately, with mice.

A UCSF stem cell study conducted in mice suggests a novel strategy for treating damaged cardiac tissue in patients following a heart attack.

Researchers at the Univ. of Copenhagen have designed, produced and patented a new chemical compound for the possible treatment of brain damage caused by stroke. The compound binds 1,000 times more effectively to the target protein in the brain than the potential drug currently being tested on stroke victims.

University of Texas researchers have found a new way to quickly repair damaged nerves in rats that might one day help people who suffer disabling injuries.

Scientists from the Florida campus of The Scripps Research Institute have for the first time designed a series of small molecules that act against an RNA defect directly responsible for the most common form of adult-onset muscular dystrophy.
