Some sea slugs sever their own heads, grow whole new bodies

Some sea slugs sever their own heads, grow whole new bodies

Science
March 8 (UPI) -- For at least two species of sea slug, decapitation is no big deal. After purposefully severing its head, a sacoglossan sea slug can regrow its entire body, heart and all. Scientists observed the phenomenon -- detailed Monday in the journal Current Biology -- while studying the development of the marine invertebrates, from eggs to adult sea slugs. Advertisement In the lab, researchers noticed the head of a sacoglossan sea slug moving around without its body. "We were surprised to see the head moving just after autotomy," lead author Sayaka Mitoh, a doctoral candidate at Nara Women's University in Japan, said in a press release. "We thought that it would die soon without a heart and other important organs, but we were surprised again to find that it regenerated the whole b...
Bodies pile up at crematorium in Germany’s virus hot spot

Bodies pile up at crematorium in Germany’s virus hot spot

Health
MEISSEN, Germany -- The caskets are stacked three high in the Meissen crematorium's somber memorial hall, piled up in empty offices and stored in hallways. Many are sealed with plastic wrapping, others are labeled “infection risk,” “urgent” or simply “COVID.”A surge of coronavirus deaths in this corner of eastern Germany has boosted business for crematorium manager Joerg Schaldach and his staff, but nobody is celebrating.“The situation is a little bit tense for us at the moment,” Schaldach said as another undertaker's van pulled up outside.The crematorium would typically have 70 to 100 caskets on site at this time of year, when the flu season takes its toll on the elderly.“It’s normal for more people to die in winter than in summer," said Schaldach. "That’s always been the case.”Now he has...
Plants might be able to help forensic scientists find dead bodies

Plants might be able to help forensic scientists find dead bodies

Science
Sept. 4 (UPI) -- Most people pass away with friends and family not too far away, but a small minority of fatalities happen far from civilization. Often, trees and other types of vegetation obscure the search for missing bodies. But in a new paper, published this week in the journal Trends in Plant Science, scientists considered the possibility that plants could help forensic scientists track down dead bodies. Advertisement "In smaller, open landscapes foot patrols could be effective to find someone missing, but in more forested or treacherous parts of the world like the Amazon, that's not going to be possible at all," senior author Neal Stewart Jr., professor of plant sciences at the University of Tennessee, said in a news release. "This led us to look into plants as indicators of human d...
New Zealand volcano: Divers deployed to find last two missing bodies

New Zealand volcano: Divers deployed to find last two missing bodies

World
New Zealand police deployed divers to look for two bodies near White Island volcano, after six bodies were retrieved in a recovery operation. The volcano erupted on Monday with 47 people there. Eight people were missing on the island, presumed dead. Another eight have already been confirmed dead and around 20 remain in intensive care with severe burns. The retrieval on Friday was launched despite the risk of another eruption. The search for the two remaining bodies will continue on Saturday morning, police said. The recovery of the bodies from White Island, also known by its Maori name of Whakaari, was delayed over safety concerns for the members of any search operation.Speaking to reporters after the bodies were retrieved, Prime...

New Zealand authorities have found six more bodies after landing on White Island to begin a high-risk operation to recover victims of Monday's volcanic eruption.One body has been successfully recovered and is now on board the Royal New Zealand Navy's HMNZS Wellington. The operation to recover the remaining bodies continues, but police have said there would be "very limited" opportunity to look for them - eight others were also killed in this weeks explosion.Authorities have faced growing pressure from families of the victims and the local community to bring back those killed as soon as possible.
