New clues about dino speed come from birds strutting through mud
Fossilized footprints can help calculate how fast dinosaurs moved. But tests with guinea fowl show that past estimates might not be right.

35 years on, Hubble continues to revolutionize astronomy
The Hubble Space Telescope is an icon in astronomy. Here are some of its most out-of-this-world images.

Lasers can eavesdrop on microbes, including viruses
They can sometimes identify not only the types, but also how many there are. One day, lasers might be able to keep track of what germs are around us.

A new dwarf planet may skirt the edge of our solar system
For the distant object, one trip around the sun takes over 24,000 years. Its orbit challenges a proposed path for a hypothetical “Planet Nine.”

Fungi have been ‘zombifying’ insects for 99 million years
Two bits of ancient amber sitting in a lab basement hold evidence of a fungus that’s become famous for controlling the minds of its victims.
- Environment
Scientists Say: Steppe
Expansive, windswept grasslands offer ample grazing for roaming herd animals and more.

This device creates rainbows of sound
A plastic structure separates the pitches in mixed sounds like white noise, much like a rainbow spreads out colors of light.

Pickleballs inspire a new way to reduce drag on vehicles
Dimples in a skin can be adjusted on demand to reduce drag or to steer where a vehicle goes.

Newfound ‘anti-spice’ compounds tame chili peppers’ heat
Five compounds make some chili peppers taste less spicy than others. Scientists are still figuring out why.

Megastars shredded by black holes offer new type of cosmic explosion
Called extreme nuclear transients, these events are 30 to 1,000 times as bright as supernovas — and their glow may persist for a year or more.

Scientists Say: Lagrange point
Between and around a two-body system — such as the Earth and sun — there are five points of prime celestial real estate.
