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.

In the first study that non-invasively measures oxytocin levels in wild animals, researchers have found in chimpanzees that this hormone likely plays a key role in maintaining social relations among both related and non-related animals.

Vanishing White Matter (VWM) disease is a devastating condition that destroys the brain's white matter. This white matter protects the axons of neurons, and leads to seizures and the progressive loss of motor function, eyesight, and speech. Also known as Childhood Ataxia with Central Nervous System Hypomyelination (CACH), the disease has no cure, and victims do not typically live longer than the early teens.
Marisol passed away from the disease in 2008, but her DNA pattern and specific genetic mutation were the basis for Prof. Elroy-Stein's breakthrough development of the first population of laboratory mice — called "Marisol's mice" — with a VWM disease mutation. With this invaluable biological tool in place, researchers have been able to make important progress into understanding how the disease functions.
Through these mice, the researchers were able to discover that VWM disease was in essence a developmental disorder — the mutation causes delayed development of the myelin that forms after birth, they reported in the journal Brain. The researchers' most recent findings, published in the journal PLoS One, add to this understanding.

Historically, the "lab rats" scientists use to test new medicines and run studies have been, well, rats. But that may be changing. A growing number of laboratories have begun using zebrafish as their test subjects, and there is reason to believe that trend is growing.

A new study has found that tamoxifen, a well-known breast cancer drug, can counteract some pathologic features in a mouse model of Duchenne muscular dystrophy (DMD). At present, no treatment is known to produce long-term improvement of the symptoms in boys with DMD, a debilitating muscular disorder that is characterized by progressive muscle wasting, respiratory and cardiac impairments, paralysis, and premature death.

In a study published in the January 18 issue of Cell, researchers from the University of North Carolina Lineberger Comprehensive Cancer Center have developed a new method to visualize aging and tumor growth in mice using a gene closely linked to these processes.

The lowly -- but very tenacious -- mussel has helped researchers develop new medical adhesives for sealing surgical incisions and other wounds.

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.
