Having trouble getting pregnant? Scientists have discovered a new reason behind unexplained infertility. After sex, female eggs send out chemical signals for sperm to approach or stay away. Researchers found that female eggs show no preference for their partner’s sperm compared to a random stranger.
Recent experiments are starting to show how circular RNA might be able to help a heart regrow itself after a heart attack.
Higher levels of oxytocin, a hormone associated with social behavior and emotional attachment, was detected in the blood of women taking birth control pills. This effect was also associated with higher life satisfaction.
A review of previous anatomy studies found that some “ancient” muscles that are normally present in other primate species may be more common in humans than previously thought
Researchers stimulated the reward center of the brain in anorexic women for up to 2 years. Results showed weight gain in anorexic women who starved themselves, and improvements in their mental health.
Are there better ways to detect the coronavirus in our body? A small study from China suggests antibody testing as a potentially more accurate method to find the coronavirus, even in people showing no symptoms.
A group of scientists collected samples from some of the initially infected COVID-19 patients to show its similarities to other coronavirus infections in humans and animals, allowing them to track where may have come from.
On Earth, gravity moves the fluids in our body downward from our head to our feet. But, the lack of gravity in space can cause an increased fluid build-up in our head. Scientists have found that spending a long time in space expands the size and volume of fluid in the brain, leading to long-term health problems.
Chinese researchers studied which animals are at risk of becoming infected with the coronavirus and if they can pass it on to others. They discovered that at high levels of exposure, cats and ferrets were more likely to become infected with the novel coronavirus. However, dogs showed no evidence of COVID-19 symptoms or viral carriers.
Brain and spinal cord injuries usually produce irreversible motor damage and paralysis. New research shows how the brain may be able to heal itself by reverting injured brain cells back into a younger state.
