Deliberate ignorance is useful in certain circumstances, researchers say
The former East German secret police, the Stasi, spied on people for years. But when given access to the Stasi files, most people didn’t want to read them, researchers found.
- Neuroscience
A rare mutation helped one man stave off Alzheimer’s for decades
The brain of a Colombian man with an inherited form of Alzheimer’s may hint at ways to halt or slow the progression of the disease.
- Space
50 years ago, cosmic rays may have caused Apollo astronauts to see lights
Apollo astronauts reported seeing flashes of light where there were none. Fifty years later, the flashes still mess with modern astronauts’ vision.
- Tech
A flower-shaped soft robot could make brain monitoring less invasive
Once inserted in the skull, the device unfurls flexible sensors that can monitor the brain's electrical activity less invasively than current methods.
- Life
The new human pangenome could help unveil the biology of everyone
The deciphered DNA includes never-before-explored parts of the genome and better represents the genetic diversity of all humans.

San Francisco airport will monitor plane waste for COVID-19 variants
The airport, working with the CDC and a biotech company, will be the first in the United States to regularly test plane sewage.
