Female eggs are picky and can reject a partner’s sperm 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.

The little molecule that repairs your heart after a heart attack Recent experiments in mice have demonstrated how a molecule of circular RNA called circCDYL might be able to help a heart repair itself after a heart attack by acting like a molecular sponge.

Recent experiments are starting to show how circular RNA might be able to help a heart regrow itself after a heart attack.

Mood Swings From Birth Control: Is Oxytocin to Blame? 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.

Muscles lost in our adult primate ancestors still appear in humans 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

Shocking the Brain—A Potential Treatment for Anorexia? 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

Antibody testing for coronavirus: what does the science say? Antibody-based testing may be able to catch positive cases missed by PCR, but it is still not accurate enough to be used as a standalone test. For best results, it should be combined with PCR testing and doctors' observations.

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.

How genes taught us about the origin of novel coronavirus 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 it may have come from.

Long Space Flights Cause Fluid Build-up in the Brain 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.

Hey, pet owners, are you quarantining your cat or dog? 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 Cells Get Younger To Heal Spinal Cord Injuries 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.
