Teaching physics from the din of flying discs
Polar bears are icons of the Arctic, elusive and vulnerable. Detailed monitoring of their populations is crucial for their conservation—but because polar bears are so difficult to find, we are missing critical data about population size and how well-connected those populations are. Scientists have now developed a new tool to help: DNA analysis using skin cells shed in the bears' footprints in...
Disc golf is booming, with record numbers of players turning up each year to partake in the disc-throwing sport. It is also whizzing and whistling. In fact, the sound a disc makes while soaring through the air toward its target is full of information about how fast the disc is flying and how quickly it spins.

El Niño helped steer storms away from U.S. this hurricane season. What about next year?
With Planet Earth running a fever, U.N. climate talks focused Sunday on the contagious effects on human health.
A six-planet solar system in perfect synchrony has been found in the Milky Way
This year, a record-hot Atlantic Ocean went toe-to-toe with a strong El Niño for which weather phenomena would steer the hurricane season. The winner?
Bottlenose dolphins can sense electric fields, study shows
Astronomers have discovered a rare in-sync solar system with six planets moving like a grand cosmic orchestra, untouched by outside forces since their birth billions of years ago.
Nations rally behind renewables at COP28 climate talks
A small team of bio-scientists from the University of Rostock's Institute for Biosciences and Nuremberg Zoo's Behavioral Ecology and Conservation Lab, both in Germany, has found evidence that bottlenose dolphins can sense electric fields. In their study, reported in the Journal of Experimental Biology, the group tested the ability of two captive bottlenose dolphins to sense a small electric field.
To greenwash or do the right thing? Corporate dilemmas at COP28
Nearly 120 nations pledged to triple the world's renewable energy within seven years at UN climate talks Saturday as the United States pushed to crank up nuclear capacity and slash methane emissions.

New unified theory shows how past landscapes drove the evolution of Earth's rich diversity of life
As seas get warmer, tropical species are moving further from the equator
Earth's surface is the living skin of our planet—it connects the physical, chemical and biological systems.
Climate change is causing tropical species in the ocean to move from the equator towards the poles, while temperate species recede. This mass movement of marine life, termed tropicalization, is leading to a cascade of consequences for ecosystems and biodiversity, and has the potential to impact the global economy.
