New antidepressant.

An antidepressant was isolated from the bark of a tropical tree. The scientists isolated the alkaloid, which they named GB18. It blocks opioid receptors and thus can act as an antidepressant. A decoction of the bark of Galbulimima belgraveana acts as an analgesic and antipyretic. The properties of GB18 may be useful in the treatment of depression and anxiety disorders - scientists are going to adapt it for human use and create medicines based on it.

Scientists have learned how to stop the reproduction of Toxoplasma

This will make the cats safe. They found two genes, without which it is impossible for the Toxoplasma gondii parasite cell to leave the host cell. The discovery was made using a genetic screening method based on the Cas9 genetic scissors. The parasite Toxoplasma gondii provokes toxoplasmosis, an infectious disease that is transmitted from cats to humans. People can also get it when they eat raw or undercooked meat. Often, toxoplasmosis is asymptomatic. In addition, Toxoplasma is related to Plasmodium falciparum, a malaria pathogen that kills hundreds of thousands of people worldwide every year. A new discovery could help rid cats of Toxoplasma gondii and thereby make them safe for humans.

In the ocean, they found tons of sugar that no one suspected

Scientists have discovered that seaweed meadows at the bottom of the ocean store huge amounts of sucrose, the main ingredient in sugar.
