This bird nest becomes a ‘fortress’ using antibird spikes
The spikes were meant to keep birds away. But five nests found in Europe may use the bird deterrents for structure and to scare off predators.

A ‘mini cyclone’ helps detect coronavirus in the air
A new device can detect from seven to 35 coronavirus particles per liter of air in minutes. That’s close to a PCR test’s sensitivity — but much quicker.
- Tech
New thermal ‘cloak’ keeps spaces from getting too hot or too cold
A prototype fabric could help keep cars, buildings and other spaces cooler during heat waves while also reducing greenhouse-gas emissions.
- Chemistry
Scientists Say: Valence electrons
These far-out electrons do the hard work when it comes to chemical reactions.
