Will you learn better from reading on screen or on paper?
Some studies find students don’t learn as well by reading on screens as from paper. But that's not always true. Here’s how to make the most of reading in either format.

A sense of touch could upgrade virtual reality, prosthetics and more
Scientists and engineers are trying to add touch to online shopping, virtual doctor appointments and artificial limbs.
- Climate
Research on climate and more brings trio the 2021 physics Nobel Prize
Syukuro Manabe and Klaus Hasselmann pioneered work on simulations of Earth’s climate. Giorgio Parisi probed complex materials.

Synthetic trees could tap underground water in arid areas
They also could also help coastal residents mine fresh water from salty sources.
- Animals
Will the woolly mammoth return?
Scientists are using genetic engineering and cloning to try to bring back extinct species or save endangered ones. Here’s how and why.

Discovering the power of placebos
If you take a fake pill and expect to feel better, you may. Researchers are learning how this placebo effect works and how to use it to help patients.
- Environment
Wildfire smoke seeds the air with potentially dangerous microbes
Studies now show that most wildfires don’t kill microbes. That’s fueling worries about what risks these smoke hitchhikers might pose to people.
