Researchers unveil drug complex that makes cancer cells self-report to immune system

Two junior research groups at Ruhr University Bochum, Germany, have developed a drug complex that kills cancer cells in such a clever manner that they raise a red flag as they die. They signal to the immune system that something is seriously wrong with this type of cell.

Brain's tiny region dictates how memories are formed and separated

Life may unfold as a continuous stream, but our memories tell a different story. We do not recall the past as one long, unbroken text. Instead, we remember it as a series of meaningful events, like how sentences are structured with grammar and punctuation.

Microplastics found to trigger cancer-linked changes in lung cells

Although the respiratory system is one of the main entry points for microplastics and nanoplastics (MNPs) from the air into the body, little is known about the effects of these tiny particles on the lungs.
