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.....»»
Light pollution has cut humanity"s ancient connection with the stars—but we can restore it
Humans are naturally afraid of the dark. We sometimes imagine monsters under the bed and walk faster down unlit streets at night. To conquer our fears, we may leave a night light on to scare away the monsters and a light over the porch to deter break.....»»

Researchers identify the neurons that synchronize female preferences with male courtship songs in fruit flies
When it comes to courtship, it is important to ensure that one is interacting with a member of the same species. Animals use multiple sensory systems to confirm that potential mates are indeed suitable, with acoustic communication playing an importan.....»»
A new understanding of reptile coloration
Snakes and mice don't look alike. But much of what we know about skin coloration and patterning in vertebrates generally, including in snakes, is based on lab mice. However, there are limits to what mice can tell us about other vertebrates because th.....»»

Mating causes "jet lag" in female fruit flies, changing behavior
An innovative technique from Cornell University researchers finds seminal fluid protein transferred from male to female fruit flies during mating changes the expression of genes related to the fly's circadian clock......»»
The Case of the Incredibly Long-Lived Mouse Cells
Scientists kept the rodents’ immune T cells active four times longer than mice can live—with huge implications for cancer, vaccination, and aging research......»»
Training ants to sniff out cancerous tumors in mice

Researchers identify protein FER1L5 as essential for male fertility in mice
Fertilization is the union of two cells: an egg and a sperm. Before the egg and the sperm fuse, an event known as the "acrosome reaction" needs to occur in the sperm. Now, a team from Osaka University has identified a protein called FER1L5 that is es.....»»
Stress may trigger male crucian carp defense against predators
Only males among the fish species crucian carp have developed a strategy to protect themselves from hungry predators, according to a new study from Lund University in Sweden published in the journal Evolution. The explanation could lie in that the su.....»»
Gene editing halts damage in mice after heart attacks in new study
Editing a gene that prompts a cascade of damage after a heart attack appeared to reverse this inevitable course in mice, leaving their hearts remarkably unharmed, a new study by UT Southwestern scientists showed. The findings, published in Science, c.....»»

Stem cell model allows researchers to explore the earliest stages of sex determination in mice and humans
During embryonic development, two different cascades of genetic signals determine whether the embryo's primordial gonad will become testes or ovaries, and thus whether the embryo will develop into a male or a female. Disruptions in this process cause.....»»
Here today, gone tomorrow: How humans lost their body hair
Orangutans, mice, and horses are covered with it, but humans aren't. Why we have significantly less body hair than most other mammals has long remained a mystery. But a first-of-its-kind comparison of genetic codes from 62 animals is beginning to tel.....»»
