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... More »

Scientists Find a Mouse That Gets Periods

Spiny mouse could help in researching human conditions

(Newser) - Just 1.5% of mammals menstruate and 99.9% of those are primates. That's why scientists are amazed by the spiny mouse—the first rodent shown to menstruate with a cycle remarkably similar to humans, according to a study that still needs to be peer-reviewed. Researchers at Monash University... More »

Scientists Can Now Control Mouse Minds With Magnets

And that could have huge implications for humans

(Newser) - Scientists at the University of Virginia were able to control the brains of living mice using magnetic fields, essentially harnessing the power of mind control, according to a study published this week in Nature Neuroscience. Researchers created a synthetic gene—dubbed Magneto, obviously—that is sensitive to magnetic fields and... More »

Brussels' New Traffic Nightmare: Hungry Mice

Rodents in Brussels don't give 2 hoots about traffic congestion, apparently

(Newser) - Decaying road tunnels have left Brussels in a perpetual state of traffic chaos, but repairs are apparently on hold due to what CityLab deems possibly "the world's worst excuse for poor infrastructure": hungry rodents. Because the transportation department was housed 25 years ago in a hotel (apparently when... More »

The Mice Have Spoken: Taste Is an Illusion

Scientists turn sense of taste on and off by manipulating brain cells: study

(Newser) - That bitter tincture a bunch of mice in a Columbia University lab recently gagged on could have been sweet nectar, or even just plain water. Why they took issue with the taste: For a study published in the journal Nature , scientists fiddled with their brain cells to make them think... More »

This Doctor Is Doing Head Transplants—Small Ones

Xiaoping Ren to perform head transplant on monkey this summer

(Newser) - A head transplant may sound like something out of a horror movie, but Dr. Xiaoping Ren has completed about 1,000 on mice. This summer, he'll attempt his first such procedure on a monkey in a case that will be closely watched. Ren, who worked in the US for... More »

The Key to Killing Lyme Disease: Mice?

Biologist develops vaccine-packed, edible pellets

(Newser) - A Tennessee scientist has developed a novel way to fight Lyme disease—and it starts with your local mice. Mice can carry the bacteria Borrelia burgdorferi, which causes Lyme, so molecular biologist Maria Gomes-Solecki decided to target the furry creatures rather than taking direct aim at the ticks that suck...

'Youth' Chemical Reverses Muscle Aging in Mice

Research team wants to begin clinical trials in 2015

(Newser) - If you have a few unwanted wrinkles, this study may pique your interest: Harvard scientists reversed a part of the aging process in mice with a muscle-rejuvenating chemical the BBC dubs "youth-medication." The chemical, NAD, decreases in cells as the body ages, but when mice were given boosted... More »

2K Dead Mice Dropped on Guam's Snake War

They're packed with Tylenol to kill invasive creatures

(Newser) - Guam has a new weapon in its war against brown tree snakes : an army of Tylenol-filled dead mice. The creatures have been dropped onto a US Air Force base using miniature cardboard parachutes, NBC News reports. The snakes, an invasive species, feast on exotic local birds and cause power outages,... More »

Mice Point Way to Male Birth Control Pill

Researcher: pill could arrive in 10 years

(Newser) - Researchers have discovered a way to block male mice from fatherhood—with minimal side effects. The technique, which could help lead to a male birth control pill, doesn't mess with hormones or with sperm itself, AFP reports. Instead, it affects sperm's ability to travel through the male body.... More »

Parasite Makes Mice Fearless of Cats

In an adaptation that probably doesn't end well for the rodents

(Newser) - Good news for cats: Mice are no longer afraid of them—at least mice that have been infected with a parasite common in mammals. Not only does Toxoplasma gondii leave mice less afraid and thus more likely to venture into striking distance, the effects last after the parasite has cleared,... More »

City Mice Smarter Than Country Mice

Study finds that human activity has made some animals evolve larger brains

(Newser) - City dwellers have evolved bigger brains than their rural counterparts, a new study suggests—at least among white-footed mice and meadow voles. University of Minnesota biologist Emilie Snell-Rood looked at the skulls of 10 species of small mammals, and found that in those two species, specimens from urban environments had... More »

World's Most Rodent-Packed Island Has Just 2 Options

Blanket island in poison, or deal with the 60K mice

(Newser) - Those suffering from musophobia would be wise to steer clear of the South Farallon Islands. The archipelago, which sits just 27 miles off San Francisco, is the most rodent-dense island in the world, with an average of 500 Eurasian house mice occupying each of its 120 acres (that's 60,...

3 Extra Sodas Per Day Can Kill You

Study shows that a "safe" diet is not so safe

(Newser) - A steady diet of sodas could hinder your ability to reproduce or even shorten your life, if lab mice are any indication. Researchers at the University of Utah gave mice a diet of 25% sugar—equivalent to three extra sodas per day in people—and found the males less likely... More »

Scientists Give Mice Fake Memories

Study could help explain our own false memories

(Newser) - Congratulations, science: You have now advanced far enough to confuse mice. A team of researchers has managed to implant a false memory in mice, in an experiment that they hope will shed light on the unreliability of human memory. The mice were introduced into one environment and given enough time... More »

US to Shower Guam With Dead Toxic Mice

PETA not pleased with snake-minded move

(Newser) - The US has a plan to deal with Guam's overwhelming snake population , and it's not sitting well with animal rights activists: In April or May, dead mice stuffed with acetaminophen will be parachuted into Guam. As the AP explains, the plan is built around the brown tree snakes'... More »

Meet the Fearsome New Tool in Airport Security

Israeli company trains mice to sniff out explosives

BioExplorers has trained its little critters to sniff out telltale signs of explosives and narcotics, reports AFP . Under its system, travelers would pass through a small booth, and mice in a nearby chamber would... More »

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.

Lab-Made Eggs Produce Healthy Mice

Points way to human infertility treatments
