Fight Against Aging Enters a 'Whole New Era'

Young spinal fluid is seen to improve memory in older mice, per new research

(Newser) - Researchers are heralding "a whole new era" in the search for Alzheimer's treatments, with a new study suggesting those treatments don't necessarily need to address damage in the brain. Tony Wyss-Coray of Stanford University previously showed infusions of blood from younger animals could reverse the effects of...

This Could Be a Novel Way to Conquer Cocaine Addiction

Scientists devise a genetically engineered skin graft that works in mice

(Newser) - Could a skin graft help cocaine addicts get clean? Scientists at the University of Chicago say their novel approach has worked in mice, reports New Scientist . And if this translates to humans, it could be a game changer, though the remedy is specific to cocaine addiction. In a new study...

'Drastic' Ketogenic Diet Helps Mice Live Longer

Scientists are looking for molecular triggers

(Newser) - All fat, easy on the carbs? At least for one particular breed of lab mice, the so-called ketogenic diet could improve various health metrics, including strength and lifespan. Per a news release , researchers report that two independent studies support the same theme: that a diet with very low to zero...

'Exciting' Find Could Mean Fewer Heart Transplants

Protein 'tricks' heart into healthier behavior

(Newser) - Scientists in Canada say they've found a way to trick the heart, making it behave as if it were the beneficiary of exercise even if no exercise was able to be done. According to a study in Cell Research , the Ottawa researchers discovered that protein cardiotrophin 1 (CT1) can...

Whole-Body Vibration Could Affect Body Like Exercise

The jury is still out on whether it works in humans

(Newser) - Remember last year's exciting finding that just a few minutes of high-intensity interval training can reap similar health benefits as 45 minutes of moderate exercise? Well, there's a chance that just sitting on a vibrating platform might also reap similar benefits, especially for those with type 2 diabetes—...

Dartmouth Ponies Up $8.4M Over Lab Animal Dumping Ground

School cleaning up land after pollution found in neighbors' groundwater

(Newser) - Neighbors of property where for years Dartmouth College disposed of mice and other small animals used in science experiments say they fear pollution has contaminated their groundwater. The site has contaminated the water of at least one family, Richard and Debbie Higgins, who blame a variety of health problems on...

Zika Virus Ravages Testicles of Male Mice

Just 2 weeks post-infection, their testes shrank visibly

(Newser) - The Zika virus has been linked to microcephaly, or shrunken heads, in the infants of pregnant women who contract the virus, but it also decimates the testicles of males—at least in mice, report researchers in the journal Nature . Little is currently known about the impact of an infection on...

Scientists Make Shrunken, See-Through Lab Mice

'We can look into the wiring of the whole mouse in high resolution'

(Newser) - If your initial reaction is one of queasiness, it would be understandable: A new technique announced Monday in Nature Methods essentially allows scientists to make dead mice see-through—by stripping the lipids and water from the animals' tissues. The fat is what makes the tissues opaque; the removal of water...

Cinnamon Might Make Us Better Learners

Mice who ate cinnamon showed improved memory, learning

(Newser) - Scientists say they've discovered "one of the safest and the easiest approaches to convert poor learners to good learners." And all you have to do is eat cinnamon. Researchers at Rush University Medical Center say that feeding cinnamon to mice with a poor learning ability turned them...

Scientists Turn Bad Memories to Happy Ones

Research could mean more effective treatment for human disorders

(Newser) - Scared to death of spiders after you found one crawling in your bed? Scientists may have discovered a way for you to find them positively cuddly. After identifying the neurons powered by positive and negative memories in mice, MIT neuroscientists found a way to use light to essentially rewrite a...

Lack of Sleep Can Fry 25% of Brain Cells

Study of mice finds brain damage with prolonged sleep loss

(Newser) - A lack of shut-eye may not just leave you feeling groggy—it could seriously injure your brain. A new study of mice has found 25% of brain cells died off after prolonged sleep loss, meant to duplicate night shifts or long hours at the office—the first evidence of its...

Fried, Grilled Meat Linked to Dementia Risk

Compound caused memory loss in mice

(Newser) - Does frying meat end up frying your brain? Researchers working with lab mice have discovered that a diet high in a compound created when meat is fried or grilled caused them to have memory loss and other problems associated with Alzheimer's disease, reports the BBC . The advanced glycation end...

Down Syndrome 'Reversed' in Mice

Researchers were able to affect the growth of the cerebellum

(Newser) - We'll start by tempering expectations: The breakthrough you're about to read about has "no direct link" to a human treatment, reports AFP , but it's noteworthy nonetheless. Scientists say they've identified a molecule that "reverses" the effects of Down syndrome in mice. The molecule is...

Is Young Blood the Fountain of Youth?

Young blood reverses some brain aging in old mice

(Newser) - Vampires have known; now research mice are beginning to learn. Experiments on mice have shown that it's possible to rejuvenate animals by giving them blood from the young, according to a Standford University study. Blood from young mice reversed some of the effects of brain aging, improving learning and...

Lab-Made Eggs Produce Healthy Mice

Points way to human infertility treatments

(Newser) - A year back, scientists in Japan produced healthy mice from lab-created sperm ; now, they've done the same with lab-made eggs. The project has big implications for humans, potentially paving the way for infertile men and women to have their own offspring. "This is quite a startling feat,"...

Ailing? Maybe Your 'Mini-Me' Mouse Can Help

Doctors implant your disease into mice to hone treatment

(Newser) - The New York Times says it "could be the ultimate in personalized medicine," and it's hard to disagree. The idea is to give mice the same disease you have—as in, implant part of your tumor into the rodents—to help doctors zero in on a precise...

'Signal Sending' Glasses Could Restore Lost Vision

Technology helps blind mice see

(Newser) - More good news for the estimated 20 million people who have lost or will lose their eyesight worldwide.
