Scientists are one step closer to developing a dengue drug and vaccine that will cover all four types of the mosquito-borne disease. There are currently no approved vaccines for dengue.
Researchers at the Singapore-MIT Alliance for Research and Technology
(SMART) have developed a humanised mouse model which will expedite the
ongoing search for an effective drug or vaccine for the infection.

The trillions of bacteria that live in the gut — helping digest foods, making some vitamins, making amino acids — may help determine if a person is fat or thin. Dr. Jeffrey I. Gordon and Vanessa K. Ridaura are two members of a scientific team whose research shows a connection between human gut bacteria and obesity. The evidence is from a novel experiment involving mice and humans that is part of a growing fascination with gut bacteria and their role in health and diseases like irritable bowel syndrome and Crohn’s disease. In this case, the focus was on obesity. Researchers found pairs of human twins in which one was obese and the other lean. They transferred gut bacteria from these twins into mice and watched what happened. The mice with bacteria from fat twins grew fat; those that got bacteria from lean twins stayed lean.

According to new research on epilepsy, zebrafish have certainly earned their stripes. Results of a study in Nature Communications suggest that zebrafish carrying a specific mutation may help researchers discover treatments for Dravet syndrome (DS), a severe form of pediatric epilepsy that results in drug-resistant seizures and developmental delays.

University of Iowa researchers say that the common fruit fly, Drosophila melanogaster, is an ideal model to study hearing loss in humans caused by loud noise. The reason: The molecular underpinnings to its hearing are roughly the same as with people.

This summer, Duke welcomed two new members to its community—each weighing no more than a handful of paperclips and standing less than three and a half centimeters tall.
Filbert and his sister Scuppernong, twin grey mouse lemurs, were born on June 18 at the Duke Lemur Center. DLC Director Anne Yoder said the birth of these twins is particularly significant in terms of the Center’s research, because mouse lemurs have been documented to show symptoms of dementia very similar to the onset of Alzheimer's in humans. By studying mouse lemur genomes, the Center hopes to shed light on the nature of Alzheimer's.

Eating lots of broccoli may slow down and even prevent osteoarthritis, UK researchers believe.
The University of East Anglia team is starting human trials following on from successful lab studies.
Tests on cells and mice showed that a broccoli compound - which humans can also get from Brussels sprouts and cabbage - blocked a key destructive enzyme that damages cartilage.

It's well known that natural redheads are at higher odds for deadly melanoma skin cancer, and new research in mice may help explain why.
Researchers at Harvard Medical School say the genetic mutation responsible for red hair and light skin also appears to promote a well-known cancer-causing pathway.

A small, native-Irish marine animal with remarkable powers of regeneration has provided stem cell scientists studying congenital defects and cancer biology with significant new leads.
Hydractinia echinata has the power to regenerate any lost body part, can clone itself, does not age biologically, and, according to Dr Uri Frank, who is leading the research at NUI Galway’s regenerative medicine institute, “in theory - lives forever”.
The tiny creature, which is a relative of jellyfish and sea anemones, is “perfect for understanding the role of stem cells in development, ageing and disease,” says Dr Frank.

A lifetime of too much copper in our diets may be contributing to Alzheimer's disease, US scientists say. However, research is divided, with other studies suggesting copper may actually protect the brain. The latest study in Proceedings of the National Academy of Sciences showed high levels of copper left the brain struggling to get rid of a protein thought to cause the dementia. The study on mice, by a team at the University of Rochester in New York, suggested that copper interfered with the brain's shielding - the blood brain barrier.

New research with worms at Rutgers may help shed light on how and why nervous system changes occur, and what causes some people to suffer from life-threatening anxiety disorders while others are better able to cope.

Scientists' latest bright idea? Bunnies that glow in the dark. A Turkish lab used a technique developed at the University of Hawaii to breed a colony of rabbits that glow bright green in the dark, in what they say is an attempt to advance research into treatments for life-threatening genetic diseases.

A cure for human deafness just might be swimming alongside the thousands of zebrafish in muggy rooms across the hall from Texas A&M University biologist Bruce Riley's office, and a recent renewal of a federal grant totaling $1.5 million over five years will move him closer to that goal.

John L. VandeBerg is the director of the Southwest National Primate Research Center and the chief scientific officer of the Texas Biomedical Research Institute. In his latest op-ed, he discusses the need for apes and chimps in research: Here is a fact about animal welfare that my opponents fail to consider: research with captive chimpanzees is vital to the development and testing of vaccines that can help save the lives not just of humans but also of wild chimpanzees and gorillas. It could even help those species from becoming extinct.
