It is fashionable to grow flowers now: this hobby has long attracted not only quiet decent pensioners, but also very extravagant people. The world of indoor plants is very diverse: for each of us there is a flower suitable in character, temperament and degree of originality.
Researchers from the Institute of Molecular Biology (IMB) and Johannes Gutenberg University in Mainz (JGU) have learned how to create membrane-free organelles in thin films.
Scientists from the University Clinic of Dusseldorf have grown an artificial brain from human skin cells, in which optical cups were formed. Biologists at the University of Cambridge taught cuttlefish a simple language and tested their episodic memory. Scientists from the University of New York have shown that an interested conversation can slow down the development of Alzheimer's disease.
Spanish scientists have found out that diabetics are much more susceptible to the severe course of COVID-19 – and explained why this happens.
Researchers from the HSE and the Institute of Bioorganic Chemistry of the Russian Academy of Sciences have demonstrated the ability of T-cell immunity to resist the 11 most common variants of SARS-CoV-2. Scientists at Northwestern University, USA have developed a method of fighting tumors using NK cells of innate immunity. Brown University scientists have shown that self-isolation negatively affects the intellectual development of children born during the pandemic.
Hemostasis (hemo — blood, stasis — stop) is fraught with many mysteries that have not yet been solved by science, despite many decades of study at the most subtle molecular and submolecular levels. Even very competent doctors at lectures on the subtleties of the hemostasis system, quite quickly begin to get tired of the abundance of names of coagulation factors, enzymes, ways of their activation – after all, blood clotting processes have hundreds of participants and components.
Stopping bleeding due to injury can save lives, but due to the abundance of blood, many patches and bandages simply refuse to stick to the skin. Researchers at the Massachusetts Institute of Technology have developed a new surgical adhesive that can stop bleeding within 30 seconds.
The release of toxic substances is a wonderful way that some species of frogs use to scare off predators. However, there is one thing — when using this method of protection, the toxin will also get on the amphibians' own skin. But scientists have found out how poisonous frogs protect themselves from their own poison.
Tree crowns are not the easiest habitat, where each branch has its own characteristics of flexibility.
