Tubeworms, snails and other weird creatures found under the seafloor

NEW YORK (AP) — Scientists for the first time have uncovered an underworld of animal life thriving beneath the seafloor.

An expedition to a volcanically active ridge in the Pacific off South America has revealed worms, snails, giant tubeworms and other strange creatures lurking below steamy underwater hot springs.

Researchers have long studied animal communities near such hydrothermal vents. Many thought only microbes and viruses could survive underneath. To their surprise, an underwater robot last summer overturned volcanic slabs and found diverse life under the vents.

“This was totally unexpected,” said study co-author Sabine Gollner with the Royal Netherlands Institute for Sea Research.

Young critters from above the seafloor could be traveling through the vents to settle in the depths, Gollner said.

The research published Tuesday in the journal Nature Communications.

Future studies will help reveal whether colonies of animal life exist below other hydrothermal vents around the globe.

“This is an initial discovery that's really promising,” said Jason Sylvan, a microbiologist at Texas A&M University who was not involved with the research.

Germans mourn attack on Christmas market with no answers about why

MAGDEBURG, Germany (AP) — Germans began Saturday mourning another violent attack and their shaken sense of security after a Saudi doctor drove a black BMW into a Christmas market teeming with holiday shoppers on Friday evening, killing at least two people, including a small child, and injuring at least 60 others in what authorities called a deliberate attack.

Authorities identified the suspect as a 50-year-old who has been living in Germany for nearly two decades and practicing medicine there. He was arrested Friday evening at the site of the attack as medical officials tended to the injured, and was taken into custody for questioning.

But on Saturday there were still no answers as to what caused the man to drive into a crowd in the eastern Germany city of Magdeburg.

The violence shocked the country and the city, bringing its mayor to the verge of tears and marring a festive event that’s part of a centuries-old German tradition. It prompted several other German towns to cancel their weekend Christmas markets as a precaution and out of solidarity with Magdeburg’s loss.

Chancellor Olaf Scholz and Interior Minister Nancy Faeser were due to travel to Magdeburg on Saturday, and a memorial service is to take place in the city cathedral in the evening.

“My thoughts are with the victims and their relatives," Scholz wrote on X. "We stand beside them and beside the people of Magdeburg.”

Magdeburg is a city of about 240,000 people, west of Berlin, that serves as Saxony-Anhalt’s capital. Friday’s attack came eight years after an Islamic extremist drove a truck into crowded Christmas market in Berlin, killing 13 people and injuring many others. The attacker was killed days later in a shootout in Italy.

Verified bystander footage distributed by the German news agency dpa showed the suspect’s arrest at a tram stop in the middle of the road. A nearby police officer pointing a handgun at the man shouted at him as he lay prone, his head arched up slightly. Other officers soon arrived and took the man into custody.

The two people confirmed dead were an adult and a toddler, but officials said additional deaths couldn't be ruled out because 15 people had been seriously injured.

“As things stand, he is a lone perpetrator, so that as far as we know there is no further danger to the city," Saxony-Anhalt's governor, Reiner Haseloff, told reporters. “Every human life that has fallen victim to this attack is a terrible tragedy and one human life too many.”

Authorities identified the suspect as a 50-year-old Saudi doctor who moved to Germany in 2006 and who had been practicing medicine in Bernburg, about 40 kilometers (25 miles) south of Magdeburg.

Saudi Arabia’s foreign ministry condemned the attack on X but did not mention the suspect’s connection to the kingdom.

Christmas markets are a German holiday tradition cherished since the Middle Ages, now successfully exported to much of the Western world.

Hours after Friday's tragedy, the wail of sirens clashed with the market’s festive ornaments, stars and leafy garlands.

Magdeburg resident Dorin Steffen told dpa that she was at a concert in a nearby church when she heard the sirens. The cacophony was so loud “you had to assume that something terrible had happened.”

She called the attack “a dark day” for the city.

“We are shaking,” Steffen said. “Full of sympathy for the relatives, also in the hope that nothing has happened to our relatives, friends and acquaintances.”

The attack reverberated far beyond Magdeburg, with Haseloff calling it a catastrophe for the city, state and country. He said flags would be lowered to half-staff in Saxony-Anhalt and that the federal government planned to do the same.

“It is really one of the worst things one can imagine, particularly in connection with what a Christmas market should bring," the governor said.
