Rat cells grew in mice brains, and helped sniff out cookies
When implanted into mouse embryos, stem cells from rats grew into forebrains and structures that handle smells.

A protein found in sweat may protect people from Lyme disease
The protein stopped Borrelia burgdorferi, a bacterium that is transmitted by ticks, from growing in dishes or infecting mice.

Here’s why pain might last after persistent urinary tract infections
Experiments in mice reveal that the immune response to a UTI spurs nerve growth in the bladder and lowers the pain threshold.

A genetic parasite may explain why humans and other apes lack tails
Around 25 million years ago, a stretch of DNA inserted itself into an ancestral ape’s genome, an event that might have taken our tails away.

Blocking an aging-related enzyme may restore muscle strength
Treating old mice with a drug that inhibits a “gerozyme” restored muscle strength, which can diminish with aging.

The first embryos from a mammal have now been grown in space
Mouse embryos in space can develop into clusters of cells called blastocysts. The result is a step toward understanding how human embryos will fare.

Snake venom toxins can be neutralized by a new synthetic antibody
A lab-made protein protected mice from lethal doses of paralyzing toxins found in a variety of snakes, a new study reports.

These windpipe cells trigger coughs to keep water out of the lungs
Neuroendocrine cells can sense substances on the way to the lungs and prompt reactions such as coughing and swallowing, experiments in mice show.

Three ways of rejuvenating aging brains may work via the same protein
Three brain rejuvenation methods may exert their effects through the same molecule, at least partly, which could lead to therapies for cognitive decline.

Taurine slows aging in mice. Will it ever work for people?
The amino acid taurine — found in meats, produced by the body and common in energy drinks — may have a role in health and aging, a new study suggests.

Spiny mice have armadillo-like armor in their tails
CT scans revealed the bony plates in the rodents’ tails. The hidden armor may protect against attacking predators or other spiny mice.

Newly identified stem cells can lure breast cancer to the spine
A new type of stem cell discovered in mice and humans might explain why cancer that spreads to other body parts preferentially targets the spine.
