For the first time ever, astronomers explored this intriguing possibility and scanned for signals coming from hidden nonhuman probes orbiting the sun.

Although sometimes heralded as a "breakthrough" in news coverage, the treatment has garnered a mixed review from doctors and scientists because of its modest effectiveness and potential side effects, as well as its price tag. Live Science asked experts what they think about lecanemab and what patients should know about the treatment.

Instead, these fearsome hunters may have used these claws to pin and grasp their helpless prey.

While these long-necked sauropods and the river are long gone, many of their nests remain intact, full of fossilized dinosaur eggs that reveal clues about how these massive herbivores nested and laid their eggs, and whether they took care of their hatchlings.

Yosuke Tanaka, who co-runs Dive Resort T-Style with his wife in Toyooka City, Japan, got the opportunity on Jan. 6 when a local ferryman called him to say that there was a large squid swimming near the surface off the coast in the Sea of Japan. Tanaka hurried over, he wrote on his blog, and was rewarded with a close-up encounter with one of the ocean's most mysterious creatures.

The new study, published to the preprint server arXiv, suggests that our current definition of the habitable zone may be too narrow because it doesn't include how life influences a world.
