Why are male mice afraid of bananas?
Researchers from McGill University have identified a form of chemical signaling in mice to defend their offspring. The researchers found that proximity to pregnant and lactating female mice increased stress hormones in males and even decreased their.....»»
Prenatal exposure to phthalates damages reproductive tissue in female mice
Phthalates are a ubiquitous family of chemicals that are used every day. In a new study, researchers have investigated how these compounds affect tissue development in the reproductive systems of female mice offspring......»»
60 years of children"s books reveal persistent overrepresentation of male protagonists
An analysis of thousands of children's books published in the last 60 years suggests that, while a higher proportion of books now feature female protagonists, male protagonists remain overrepresented. Stella Lourenco of Emory University, U.S., and co.....»»
Best Newegg deals for December 2021
Newegg is a hotspot for tech deals. We've rounded up the best sales on GPUs, gaming laptops, keyboards, wireless mice, and other great Newegg deals......»»
New hope for people living with a genetic cause of autism
Researchers report they were able to ameliorate Fragile X syndrome symptoms after inserting the Fmr1 gene into the brains of very young transgenic mice that had been genetically engineered to lack this gene. When the researchers measured brain activi.....»»
Boosting anti-cancer action by driving up immunity at tumor site
Driving up the immune response at the site of a cancer tumor with nanotechnology may help enhance immunotherapy treatments in advanced stages of the disease, new research in mice suggests......»»
Queen"s genes determine sex of entire ant colonies
Researchers have discovered the genetic basis for a quirk of the animal kingdom—how ant queens produce broods that are entirely male or female......»»
Experimental treatment with enzyme protects mice from lethal anthrax infection
Scientists have demonstrated that modifying an enzyme produced by the bacterium that causes anthrax can protect mice from infection with the deadly disease. Their findings suggest a potential therapeutic strategy for treating multidrug-resistant stra.....»»
How bone-bordering cells may help shape a skull
In a study of mice, scientists showed how the activity of one gene, turned on in a newly discovered group of bone-bordering cells, may play an important role in shaping the skull. The skulls of mice that were missing the gene were misshapen and were.....»»
Experimental mRNA HIV vaccine safe, shows promise in animals
An experimental HIV vaccine based on mRNA -- the same platform technology used in two highly effective COVID-19 vaccines -- shows promise in mice and non-human primates, according to scientists. Their results show that the novel vaccine was safe and.....»»
Fine-tuning motivation in the brain
Neuroscientists have discovered a set of brain cells that influence the motivation of mice to perform tasks for rewards. Increasing the cells' activity makes a mouse work harder or more vigorously. The neurons come with a feature that prevents the mo.....»»
The best gifts for men: 50+ ideas for the man in your life
No two guys are the same, and not every man spends their days dreaming of whiskey stones. (In fact, we'd guess that very few of them do.) Traditional male stereotypes are a thing of the past, y'all, and it's time we started embracing that fact when w.....»»
Xiaomi 12 Ultra could have an absolutely bananas rear camera bump
Xiaomi 12 series cases have leaked, and the Ultra model has a bonkers rear camera bump with a huge array of lenses......»»
Scientists show how bone-bordering cells may help shape a skull
A skull is not one single bone but rather a collection of bone plates joined together early in development. In a study of mice, scientists at the Icahn School of Medicine at Mount Sinai showed how the activity of one gene, turned on in a newly discov.....»»
Spaceflight wreaks havoc on liver metabolism
Researchers have demonstrated that microgravity and other environmental factors in space play different roles in inducing oxidative stress, which, in turn, alters the metabolism of sulfur-containing compounds in the liver of mice. The study highlight.....»»
Blood from marathoner mice boosts brain function in their couch-potato counterparts
Researchers have shown that blood from young adult mice that are getting lots of exercise benefits the brains of same-aged, sedentary mice. A single protein in the blood of exercising mice seems largely responsible for that benefit......»»
Research reveals how aging cells can be an underlying cause of kidney damage
A study in mice has found that stress and tissue damage initiated by angiotensin II, a molecule that is known to increase blood pressure and stiffening in the linings of blood vessels, leads to cellular senescence, a process by which a cell ages and.....»»
Bird singing contests: A clash of culture and conservation
For thousands of years, people have been keeping wild birds. It is often a deeply ingrained part of the culture. One of the more recent trends to emerge from this practice is the singing contest which pits male birds against each other to impress h.....»»
Coaxing jellyfish, flies and mice to regenerate body parts
Caltech researchers have discovered certain conditions that enable different laboratory animals to regenerate amputated appendages. Upon consuming a diet high in sugar and an essential amino acid, three different species—the moon jellyfish Aurelia.....»»
Examining the neurotoxin from a black widow
Phobias are often irrational by nature—especially in the case of spiders, as these creatures are usually more afraid of humans than vice-versa. But: some species are a force to be reckoned with—for example, the Latrodectus spider, more commonly k.....»»
Immune system-stimulating nanoparticle could lead to more powerful vaccines
Researchers designed a new nanoparticle adjuvant that may be more potent than others now in use. Studies in mice showed it significantly improved antibody production following vaccination against HIV, diphtheria and influenza......»»
