Researchers at the University of Bonn in Germany are investigating how the internal engines of machine learning applications in drug research work. Among other things, they discovered that the artificial intelligence systems have become quite lazy

Researchers have succeeded in deciphering the movement mechanism of the plant hormone gibberellin, which is of great importance to humanity

According to the researchers, it is a hormone, a small signal molecule, which controls the growth of plants. The decoding may help a lot in expanding agricultural crops and dealing with the global food crisis

A nanocapsule of nucleic acids and peptides that releases the medicine inside in response to defined enzymes. (1) in the first step the peptide undergoes cross-linking on the surface of the nanoparticle; (2) In the next step, a defined enzyme recognizes the peptide cross-linking group, (3) and in the last step, the enzyme's release leads to the release of the drug or the nucleic acids that were locked inside the capsule.
