A study that followed pregnant women living in Denmark found that even low nitrate levels in drinking water — about half of the allowable level set by the U.S. Environmental Protection Agency — caused an adverse effect of fetal growth.

A team of chemists has developed a simple and efficient method to synthesize tetrahydroisoquinolines – important molecules used in drug discovery.

The U.S. Food and Drug Administration issued an emergency use authorization (EUA) for bamlanivimab and etesevimab administered together for the treatment of mild to moderate COVID-19 in adults and pediatric patients (12 years of age or older weighing at least 40 kilograms [about 88 pounds]) who test positive for SARS-CoV-2 and who are at high risk for progressing to severe COVID-19.

Adult progenitor cells are maintained throughout Drosophilia fly development and they are responsible for giving rise to adult tissues and organs. The headcase (hdc) gene has been identified as being responsible for the unique characteristics of adult progenitor cells.

A drug called ProAgio has been shown to be effective at treating pancreatic cancer and prolonging survival in a study using mice. An additional study demonstrated that the drug is also effective against triple-negative breast cancer.

Wearable devices can identify COVID-19 cases earlier than traditional diagnostic methods and can help track and improve management of the disease, Mount Sinai researchers report in one of the first studies on the topic.

A team of engineers and scientists has developed a method of "multiplying" organoids. The researchers used their method to culture and grow a "mini-airway", the first time that a tube-shaped organoid has been developed without the need for any external support.

A simple blood test has been developed that can detect a wide range of diseases. The test allows lab technicians to identify and determine the state of the dead cells throughout the body and thus diagnose various diseases including cancers and diseases of the heart and liver.

A new study concludes that about half of global wastewater is treated, rather than the previous estimate of 20%. Despite this promising finding, the authors warn that treatment rates in developing countries are still very low.

Researchers have reported a way to train machines to predict the function of DNA sequences. They used "neural nets", a type of artificial intelligence (AI) typically used to classify images. Teaching the neural net to predict the function of short stretches of DNA allowed it to work up to deciphering larger patterns.
