mice stories: 13 news summaries

(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... More »

Caffeine May Reverse
Effects of Alzheimer's

Stimulant alleviates cognitive decline in lab mice

Jul 6, 09 2:49 AM CDT
(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... More »

Rodent Rights Activists Face Uphill Climb

Animal campaigners seek a better quality
of life for lab rats

May 16, 09 11:24 AM CDT
(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... More »

(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... More »

 Scientists Wipe 
 Mouse Memories 

Treatment selectively erased memories of electric shocks

Oct 25, 08 3:41 AM CDT
(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... More »

100M-Year-Old DNA Regions Baffle Experts

Mice, humans share mysterious code immune to evolution

Oct 9, 08 3:11 PM CDT
(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,... More »

Of Mice and Men, and a Cure for Colds

Researchers find a
way to infect rodents with rhinoviruses

Feb 4, 08 9:16 AM CST
(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... More »

LAPD Gets Cats to Scare Rats

Feral felines spook rodents that were running over desks, digging into bags

Dec 29, 07 1:28 PM CST
(Newser) - The LAPD is using six feral felines to shoo away pesky rats and mice from its lots, the Los Angeles Times reports. The mangy, homeless creatures can't be broken in as house pets, so an animal rescue group placed them with the city’s finest to control its rodent... More »

Skin Stem Cells Cure
Sickle Cell in Mice

Latest advance in revolutionary research

Dec 7, 07 3:28 AM CST
(Newser) - In the latest advance in revolutionary new stem cell research, scientists have cured sickle-cell anemia in mice using stem cells made from skin. It's the first proof that such cells can be used to cure hereditary diseases. But because the cure involved the use of viruses to alter DNA, significant... More »

New Stem Cells Cancer-Free

Kyoto scientists nix tumors in mice with new cell cocktail

Dec 1, 07 3:33 PM CST
(Newser) - Scientists who recently turned skin into embryonic stem cells are now tweaking the process to reduce cancer risk, Reuters reports. A team at Kyoto University grew live mice with a cell cocktail, but said the rodents grew tumors. So they nixed a gene called c-Myc1 and the next batch came... More »

Lab Creates Speedy, Lean Mighty Mouse

Modified critters have voracious appetites but manage to stay thin

Nov 2, 07 1:45 PM CDT
(Newser) - Scientists have made speedy super mice by flipping a genetic switch, reports the Guardian. The mice can run 30 times as far as regular mice, and they live longer and breed later. They also eat 60% more food than average mice but manage to stay leaner and possibly more resistant... More »

Mouse Stem
Cell Discovery Speeds Cures

'Missing link' embryonic cell boosts fight against Parkinsons, diabetes

Jun 28, 07 4:29 AM CDT
(Newser) - British scientists have discovered a new type of stem cell in mice that's much closer to human embryonic stem cells, making them invaluable in the search for cures for diseases like Parkinson's and diabetes. Two independent teams from Oxford and Cambridge today revealed the "missing link" cells, which can... More »

Stem Cell Breakthrough Spares Embryos

Technique sidesteps both ethical and technical difficulties

Jun 6, 07 5:48 PM CDT
(Newser) - Normal skin cells can be transformed into the equivalent of stem cells in mice, researchers report, and the new technique may revolutionize research on humans. Because it doesn't involve embryos or eggs, the process skirts the ethical quagmires surrounding human stem cell research; the easy availability of raw material and... More »
