Scientists have created a reversible contraceptive microneedle patch that is able to slowly release the hormone levonorgestrel, through the skin. The study was published November 6, 2019, in Science Advances.

Inspired by diving bell spiders and rafts of fire ants, scientists have created a metallic structure that is so water repellent, it refuses to sink—no matter how often it is forced into water or how much it is damaged or punctured.

Investigators have found that sesame allergy is common among children with other food allergies, occurring in an estimated 17% of this population.

Researchers have identified a group of proteins that are involved in the development of the sense of smell and onset of puberty in mice, which could improve our understanding of the reproductive condition, Kallmann syndrome.

A team of scientists from City University of Hong Kong (CityU) and the Karolinska Institute has created a novel protein that can increase the target accuracy in genome editing.

Researchers have developed a micromachine that can perform different actions. The microrobots are magnetically programmed via nanomagnets contained within their components, before the various movements are controlled by magnetic fields. Such machines, which are only a few tens of micrometres across, could be used, for example, in the human body to perform small operations.

A new study in mice shows age-related decreases in blood flow to the brain and memory loss can be modified with the drug rapamycin.

Thinking about sex and gender would help scientists improve their research, a new article published today argues. Writing in a special 150th anniversary edition of Nature, five experts say these factors are too often ignored.

People who have trouble sleeping could be more likely to have a stroke or heart attack, according to a new study.

A new study shows, in animal models, that components of marijuana, including its cannabinoids THC and CBD, can cause brain and facial birth defects if used during the first trimester of pregnancy.
