High in the toxic atmosphere of the planet Venus, astronomers on Earth have discovered signs of what might be life. If the discovery is confirmed by additional telescope observations and future space missions, it could turn the gaze of scientists toward one of the brightest objects in the night sky. Venus, named after the Roman goddess of beauty, roasts at temperatures of hundreds of degrees and i
VIENNA — For an East European of my generation, watching the current protests in Belarus is like going through an old photo album. The scenes of striking workers call forth the shipyards of Gdansk, Poland, and the Solidarity movement of the 1980s. Moscow’s dilemma whether to offer President Aleksandr G. Lukashenko’s regime “friendly” support reminds me of Czechoslovakia in 1968, when Soviet troops

After all, hibernation — a state of reduced metabolism — is a good strategy for making it through long, harsh winters when food can be scarce. Biologist
TOKYO — Prime Minister Shinzo Abe of Japan said on Friday that he was resigning because of ill health, thrusting his country, during a global pandemic, into a new period of political uncertainty after a record-setting tenure that provided unaccustomed stability at the top. Mr. Abe, 65, announced his decision to step down just four days after he had set a record for the longest uninterrupted run as
An artist’s rendering of the Triassic Era aquatic reptile Tanystropheus. Its nine-foot neck contained only 13 vertebrae.Credit...Emma Finley-Jacob Nearly 250 million years ago, a very odd reptile patrolled the shorelines and coves of the Triassic Alps. Called Tanystropheus, it had a toothy head and a body echoing that of modern monitor lizards. But between them stretched a horizontal, giraffe-like
Mars is the darling of many planetary scientists, who continue to visit it through increasingly advanced robotic explorers. But don’t forget that our planetary neighbor is adorned with two moons: puny Phobos, a lumpy mass 17 miles across; and diminutive Deimos, just 9 miles long. Their names in ancient Greek may mean “fear” and “dread’, but the aesthetics of these Lilliputian space potatoes inspir
As Japan Nears 1,000 Daily Coronavirus Infections, It Shies From Restrictions Case numbers are climbing fast, with virus clusters in nursing homes, schools and elsewhere. But fingers are being pointed at Japan’s so-called hostess bars. Visitors in the Kabukicho district of Tokyo on Friday. Most of Japan’s recent coronavirus cases have been among people in their 20s and 30s, who tend to suffer only
About 3,000 years ago, people on the eastern edge of Asia began sailing east, crossing thousands of miles of ocean to reach uninhabited islands. Their descendants, some 2,000 years later, invented the double-hulled canoe to travel even farther east, reaching places like Hawaii and Rapa Nui. Archaeologists and anthropologists have long debated: Just how far did the Polynesians’ canoes take them? Di
