Hungary 1956 'Well over a 100k people fled the country seeking asylum. Among them was a young geneticist named George Rédei, who headed for the Austrian border with a small vial of seeds tucked in his pocket. The seeds belonged to a spindly weed in the mustard family called Arabidopsis thaliana.'

How a humble weed became a superstar of biology
Arabidopsis thaliana was always an unlikely candidate for the limelight. But 25 years ago, the diminutive thale cress launched the botanical world into the molecular era.

The discovery of DNA and the triplet code inspired me to be a molecular biologist and for that I’m grateful. Forget James Watson. Franklin, Crick, Brenner and Sanger are the heroes in this story.

Why do some people leap to help while others hold back? New research traces these choices to how we perceive need, merit, and fairness, patterns that stay surprisingly stable over time.

What shapes kindness?
People appear to have stable individual differences in their tendency to perceive neediness or deservingness of others, which in turn shapes their willingness to help others.
