Gene Therapy Corrects Monkey Color Blindness

Researchers used gene therapy to cure red-green color blindness in adult monkeys. The accomplishment is an important step toward developing gene therapy treatments for eye conditions in humans.

Timing of Meals May Affect Weight Gain

Mice fed a high-fat diet during their normal sleep and rest period gained significantly more weight than mice fed the same diet during their active hours, a new study shows. The finding suggests that when we eat may influence how we pack on pounds.

Sensor data shows 9 panels with different colored dots.

Electronic Nose Sniffs out Toxins

While physicists have radiation badges to protect them in the workplace, chemists and workers who handle chemicals don't have equivalent devices to monitor their exposure to potentially toxic chemicals. Researchers have now moved one step closer to developing a small, wearable sensor that can sniff out poisonous gases and toxins.

Prevention System Reduces Risky Behavior in 10-14 Year Olds

A community-focused prevention system helps keep middle schoolers from starting to engage in risky behaviors like alcohol and tobacco use, according to a new study.

Mending Vision in Patients with Eye Vein Clots

Injecting the eye with corticosteroids can improve vision in patients who have blood clots clogging a vein in the eye, according to 2 new reports. But for a subset of patients with blockages in small branches of the vein, laser treatment may be a better option.

Gene Regulates Sleep Length

Researchers have found a genetic mutation associated with waking up early. The discovery is a major step in understanding how the body controls sleep.

Antibodies Reveal a New HIV-1 Vaccine Target

Researchers have discovered 2 new human antibodies that neutralize the virus that causes AIDS. The finding points to a promising new target for vaccine development.

Monkey DNA Swap May Block Mitochondrial Disease

A new technique for exchanging DNA between egg cells has led to the birth of 4 healthy monkeys, scientists report. The method may one day provide new options for preventing certain inherited disorders that pass from mother to child in mitochondria, the tiny capsule-shaped structures that create energy inside nearly all the body's cells.

Three Gene Variants Account for Most Dog Coat Differences

The wide range of coat textures seen in dogs—from the poodle's tight curls to the beagle's straight fur—stems from variants in just 3 genes acting in different combinations, according to a new study. The finding shows how an array of traits can be reduced to the effects of just a few genes.
