Undead planets: The unusual conditions of the first exoplanet detection
 
The first ever exoplanets were discovered 30 years ago around a rapidly rotating star, called a pulsar. Now, astronomers have revealed that these planets may be incredibly rare. The new work will be presented tomorrow (Tuesday 12 July) at the National Astronomy Meeting (NAM 2022) by Iuliana Nițu, a Ph.D. student at the University of Manchester.

Pocket gophers are the only farming mammals besides humans

Tax Cuts and Jobs Act did little to affect executive pay, counter to what Congress intended

New research finds the change has had little effect, with CEO pay either staying the same or growing after the law made it more costly to award executives with high levels of compensation.

Programmed cell death in cancer cells: Overcoming resistance through paraptosis-inducing compounds
 
Apoptosis, a type of programmed cell death (PCD), is a biological process through which unwanted cells are eliminated in multicellular organisms.

This process is especially important for the treatment of cancer, since inducing cell death in cancer cells can help in their elimination.
