Baldness Cure Discovered by Accident?

Single jab reversed hair loss in lab mice

(Newser) - Researchers studying stress hormones were surprised to stumble upon what appears to be a cure for baldness—at least in mice. Mice who had gone bald due to overproduction of a stress hormone were treated with a compound that blocks stress in the gut and then returned to cages where...

Rodents: The New Airport Bomb Sniffers

In Israel, mice being trained to detect explosives, drugs

(Newser) - Which would you rather be exposed to: those pesky new “naked” airport scanners , or … rodents? In Israel, mice are being trained to sniff out bombs and drugs, in a system researchers say will be more accurate than pat-downs, x-rays, or sniffer dogs. The mice would be hidden in...

'Brown Fat' Shots Could Beat Obesity

Scientists convert mouse cells into energy-burning fat

(Newser) - Scientists looking into ways to fight fat with fat say they've made a breakthrough that could yield effective treatments for obesity. Researchers experimenting on obese mice believe they've found a way to turn white fat cells into energy-burning brown fat cells, io9 reports. Converted cell cultures injected into the mice...

Scientists Reverse Aging in Mice

Could the process work for humans?

(Newser) - Harvard scientists have reversed the aging process in mice, injecting them with an enzyme that healed tissue and reportedly spurred the growth of new neurons in their brains. Now they’re wondering if they can apply some of these benefits to humans. But differences between human and mice bodies make...

Key Depression Gene Identified

May pave way for new drugs, scientists say

(Newser) - American scientists have identified a gene that appears to play a key role in the onset of depression , a finding which may help researchers develop new treatments. A team from Yale University found that a gene called MPK-1 is twice as active in those who suffer from depression. The gene...

Why Kids With Autism Hate Hugs

Delayed brain development linked to 'hug-avoidance'

(Newser) - New research suggests that sensitivity to touch, a common symptom of autism, might be caused by delays in brain development in the womb. The study looked at brain development in mice with Fragile X, a condition closely linked to autism. Researchers found that parts of the brain linked to touch...

Mice Prove Gender Isn't Fixed at Birth

Battle of the sexes rages inside each individual

(Newser) - If you think your gender is a fixed part of who you are, a pioneering study suggests you should think again. In it, scientists turned the ovary cells of adult female mice into male testicular tissue by switching off a single gene—one that's found in all mammals. The study...

Caffeine Won't Actually Make You Sober

And combo with booze may breed dangerous overconfidence

(Newser) - Caffeine doesn't sober you up, but it does make you feel less drunk, and that combination could have dangerous consequences, a new study suggests. Researchers came to the conclusion after giving mice alcohol and caffeine, together and separately, and comparing how they navigated a tricky maze, reports Scientific American .

Yale Suspect Scolded Victim Over Lab Mice

(Newser) - If Ray Clark did, as police apparently suspect, kill Annie Le, investigators have an odd theory about his motivation, the New York Daily News reports. In emails that caught their attention, the Yale lab technician scolded Le about her lax handling of mice in the lab. Le apologized, but investigators...

Caffeine May Reverse Effects of Alzheimer's

Stimulant alleviates cognitive decline in lab mice

(Newser) - Caffeine may reverse the effects of Alzheimer’s disease, a new study indicates. University of Florida researchers investigated the effects of a high caffeine diet on mice genetically engineered to suffer from high levels of beta-amyloid—a protein associated with human Alzheimer's—that causes cognitive decline in old age. The...

Rodent Rights Activists Face Uphill Climb

Animal campaigners seek a better quality of life for lab rats

(Newser) - Activists have managed to improve the lives of many animals in recent years, but they've met indifference when it comes to getting a better deal for rodents, the Wall Street Journal reports. Rats and mice make up 90% of the animals used in research in the US, say advocates, but...

Mice Spark Blaze That Scorches 100 Cats

(Newser) - Mice started a fire in a Toronto animal shelter that killed 100 cats and three dogs, the Telegraph reports. The rodents likely sparked the blaze by chewing through electrical wires. Canadians nationwide have been donating money and offering temporary homes and meals for the few animal survivors. “People are...

Scientists Wipe Mouse Memories

Treatment selectively erased memories of electric shocks

(Newser) - Scientists have succeeded in blanking selected memories from the brains of mice, Reuters reports. After brain protein levels were manipulated, the mice lost the memory of an electric shock but didn't forget anything else. The researchers said it was doubtful that it would be possible—or desirable—to do the...

100M-Year-Old DNA Regions Baffle Experts

Mice, humans share mysterious code immune to evolution

(Newser) - Certain regions of mammalian DNA with no discernible purpose have one perplexing characteristic in common: They have survived, without mutation, for as long as 100 million years, LiveScience reports. Scientists speculate that the areas have some deep purpose, but for now they know only that they are “ultraconserved regions,...

Of Mice and Men, and a Cure for Colds

Researchers find a way to infect rodents with rhinoviruses

(Newser) - Scientists have managed to give a mouse a cold. May not sound like a huge deal, but it is: One reason a cure for the common cold has been so elusive is that until now, only primates have been infected with rhinoviruses, which cause them. Now a team at Imperial...
