Previously unknown colonies of emperor penguins have been spotted in new satellite imagery. Emperor penguins, considered “near threatened” with extinction, are the world’s largest penguins. At least some emperor penguins are moving their colonies as melting ice from climate change threatens breeding grounds, according to research released on Wednesday. “Emperor penguins have taken it upon themselves to try to find more stable sea ice,” he said. Scientists currently know of 66 emperor penguin colonies.

Chinstrap penguins take catnaps instead sleeping for a long period of time, researchers found. Chinstrap penguins in Antarctica need to guard their eggs and chicks around-the-clock in crowded, noisy colonies. Chinstrap penguins, named for the thin line of black facial feathers resembling a chinstrap, usually lay their eggs in pebble nests in November. For the first time, the scientists tracked the sleeping behavior of chinstrap penguins in an Antarctic breeding colony by attaching sensors that measure brain waves. "For these penguins, microsleeps have some restorative functions — if not, they could not endure," he said.

WASHINGTON (AP) — It's a challenge for all new parents: Getting enough sleep while keeping a close eye on their newborns. For some penguins, it means thousands of mini-catnaps a day, researchers discovered. Chinstrap penguins in Antarctica need to guard their eggs and chicks around-the-clock in crowded, noisy colonies. These short “microsleeps,” totaling around 11 hours per day, appear to be enough to keep the parents going for weeks. “For these penguins, microsleeps have some restorative functions — if not, they could not endure,” he said.

They wanted to investigate the rocks that may contain insights about the contents locked within Earth’s core and mantle, the mostly solid layer of Earth’s interior located beneath its surface. Helium inherited from the solar nebula likely became locked in Earth’s core as the planet formed, making the core a reservoir of noble gases. “So, the helium we measured in these rocks would have escaped the core perhaps 100 million years ago or possibly much earlier.”Helium leaking from Earth’s core doesn’t affect our planet or have any negative implications, he said. If so, have fluxes of these elements from the core over (Earth’s) history influenced planetary evolution? I am excited to investigate links between helium and other light elements,” Horton said.

This could suggest the Earth's core is "leaking" helium. The study suggests the Earth's core may be leaking the rare helium, upheaving the belief that the giant ball of molten iron at the center of our planet is sealed away.

Back then, no one knew what the ocean floor looked like — until one woman used her many talents to find out. When she reflected on her life, geologist Marie Tharp recollected being able to fill in the blanks of the ocean floor, which she saw as a fascinating jigsaw puzzle. Their final project together was the World Ocean Floor Map. The Heezen-Tharp “World Ocean Floor” map painted by Heinrich Berann.

CNN —A NASA astronaut on her inaugural spaceflight and two cosmonauts launched aboard a Russian Soyuz spacecraft toward the International Space Station Friday, marking the first time Russia has launched astronauts to the orbiting outpost in nearly a year. The Soyuz MS-24 spacecraft launched from the Baikonur Cosmodrome in Kazakhstan at 11:44 a.m. ET and began a quick, three-hour trajectory to rendezvous with the space station. Once at the space station, the group will prepare to take over operations from a trio of crew members that have been on the space station for nearly a year after launching aboard the Soyuz MS-22 vehicle. The most recent SpaceX flight arrived at the space station in August, carrying astronauts from NASA, Roscosmos, the Japan Aerospace Exploration Agency and the European Space Agency.

But not all experts were so surprised by the discovery. “I think it makes perfect sense,” said Julie Huber, a marine geochemist and microbiologist at the Woods Hole Oceanographic Institution in Massachusetts who wasn’t involved with the work. “The shallow subseafloor, where temperatures are likely cool enough for animals to survive, is what I think of as a ‘subseafloor conveyor belt’ for microbes, nutrients and, now, animals.”Much about these unusual habitats is a mystery. Deep below, the magmatic heat roasts percolating seawater, which jets back out into the water column as superheated, mineral-rich soups. Despite their extreme natures, these vents are metropolises of strange critters.

A key system of Atlantic Ocean currents may collapse anytime between 2025 and 2095, a new study found. Potential impacts include permanent drought in Western Africa and extreme winters in Western Europe. In 2019, the United Nations Intergovernmental Panel on Climate Change predicted the stream would collapse sometime after 2100. The effects of such a collapse could include permanent drought in Western Africa, extreme winters in Western Europe, and disruptions to monsoon patterns in India, South America, and Western Africa, CNN reported in 2021. The authors of the study included recommendations to mitigate the collapse of the system, including immediate moves to eliminate planet-warming pollution.

The AMOC is a complex tangle of currents that works like a giant global conveyor belt. It transports warm water from the tropics toward the North Atlantic, where the water cools, becomes saltier and sinks deep into the ocean, before spreading southwards. The likeliest point of collapse is somewhere between 2039 and 2070, Ditlevsen said. Warming oceans and melting ice threaten to desatbilize a crucial system of ocean currents in the Atlantic. “The key point of this study is that we don’t have much time at all to do this,” de Menocal said.

The LatestDebris and presumed human remains from the Titan submersible have been recovered and returned to land, the U.S. Coast Guard announced Wednesday night, nearly a week after an international search-and-rescue operation ended and the vessel’s five passengers were presumed dead. At a Canadian Coast Guard pier in St. John’s, Newfoundland, on Wednesday, crews unloaded what appeared to be the Titan’s 22-foot hull, crinkled and twisted with exposed wires and cables. United States medical professionals “will conduct a formal analysis of presumed human remains that have been carefully recovered within the wreckage at the site of the incident,” the Coast Guard said in a statement. The U.S. Coast Guard is leading the investigation into why the submersible imploded and has convened a marine board of investigation, the highest level of investigation in the Coast Guard. The discovery suggested a “catastrophic implosion” with no survivors, according to the U.S. Coast Guard.

In Mr. Rush’s telling, innovation was the province of maverick individuals, not stodgy legacy players and certainly not cumbersome government bureaucracies. That story is often wrong, and it was 100 percent wrong in this case. Realizing this could be a powerful military communications tool, they worked with the U.S. Navy to develop technologies that exploited this sound channel. As its name suggests, Aluminaut was developed with the Reynolds Metals Company, one of the largest aluminum companies in the world. What the Navy and Woods Hole were not willing to do, however, was to risk lives.

Debris from the lost submersible Titan has been returned to land after a fatal implosion during its voyage to the wreck of the Titanic captured the world's attention last week. Twisted chunks of the 22-foot submersible were unloaded at a Canadian Coast Guard pier on Wednesday. The Coast Guard is leading the investigation into why the submersible imploded during its June 18 descent. Coast Guard representatives declined to comment on the investigation or the return of debris to shore on Wednesday. Representatives for the National Transportation Safety Board and Transportation Safety Board of Canada, which are both involved in the investigation, also declined to comment.

What lies at the bottom of the oceanWhile what’s considered the deep ocean extends from 3,280 feet to 19,685 feet (1,000 meters to 6,000 meters) beneath the surface, deep-sea trenches can plunge to 36,000 feet (11,000 meters), according to the Woods Hole Oceanographic Institution in Massachusetts. Alessandro Mancini/Alamy Stock PhotoWhy mapping the ocean is so challengingFrom a strictly scientific perspective, touristic trips to the ocean floor do little to advance our understanding of the ocean’s mysteries. “We want to go to the highest, the lowest, the longest.”But only a “very small percentage of the deep ocean, and even the middle ocean, has been seen by human eyes — an infinitesimal amount. “However, 150 years of modern oceanography have led to better understanding of many aspects of the ocean such as the life it contains, its chemistry and its role in the Earth system.”Mapping the ocean “helps us to understand how the shape of the seafloor affects ocean currents, and where marine life occurs,” Rogers added. Researchers say the ocean and the life it contains could provide answers to some of medicine’s biggest challenges, such as antibiotic drug resistance.

We fell for an hour, the views out of our observation ports fading slowly to pitch darkness. It was my first submersible dive, in 1993. Now it was the expedition’s last dive after days of frustration caused by bad weather and struggles to find what the scientists were hunting for. My experience also illuminates the risks that the passengers of the Titan submersible ran when they decided to dive on the resting place of the Titanic. But so far they had struck out because of poor weather and equipment difficulties.

That is a large number, given there are fewer than 350 North Atlantic Right Whales remaining, including just 70 breeding females, say regulators, researchers and conservationists. North Atlantic Right Whales who live off the eastern North American coast stretching from Florida to the Canadian Maritimes provinces are now on the verge of extinction. Traditional lobster fishing uses traps that sink to the ocean floor and are connected by a rope to a buoy floating at the surface. Ropeless gear, by contrast, only deploys a rope and buoy to the surface when its owner activates a release trigger by remote control. When the 2,100 square-kilometer zones are shut, only harvesters with ropeless gear are allowed to fish there, Gilchrist said.

Conventionally, nylon is mostly made from ingredients sourced from fossil fuels like coal, natural gas or crude oil. "It's been estimated that 8 to 10 percent of all human-associated nitrous oxide emissions come from this single industrial process" to make adipic acid, Wallace told CNBC. To make the nylon precursor used in the Lululemon shirts, Geno uses biological organisms instead of chemicals from fossil fuels. "Because nylon, like it or not, has a lot of good value," Reddy told CNBC. "Look at those first-generation replacement straws — they didn't work, and everybody's annoyed," Reddy told CNBC.
Almost 38 years after the wreck of the “unsinkable” Titanic was first discovered at the bottom of the North Atlantic, previously unseen footage has been released.

Almost 38 years after the wreck of the “unsinkable” Titanic was first discovered at the bottom of the North Atlantic, previously unseen footage has been released. Researchers from the Massachusetts-based Woods Hole Oceanographic Institution located the remains of the famed ocean liner in 1985, and returned a year later to take a three-person submersible thousands of feet below the surface to investigate.
The footage from Woods Hole Oceanographic Institution (WHOI) was shot about 2 miles (3 km) below the ocean's surface, just months after explorers found the wreckage in 1985. Since the discovery, several documentaries about the Titanic have showed footage of the wreckage scene. During 11 dives in July 1986, footage was shot by cameras on a human-occupied submersible and a small remotely operated vessel that maneuvered through tight spaces. The unveiling of the footage has been timed with the re-release of director James Cameron's 1997 film "Titanic" on its 25th anniversary. "By releasing this footage, WHOI is helping tell an important part of a story that spans generations and circles the globe."
The Woods Hole Oceanographic Institution says it will release 1986 footage of the Titanic on Wednesday. Saturday was the 25th anniversary of James Cameron's "Titanic" based on the tragic ocean liner. The 80-minute uncut and unnarrated video, which will be uploaded by the Woods Hole Oceanographic Institution to WHOI's YouTube channel at 7:30 p.m. ET Wednesday, captures some never-before-seen images of the ocean liner that sank, killing about 1,500 in April 1912, according to AP News. One Titanic historian hobbyist told Insider, "The Titanic is such a phenomenon that any new information you can get from it is instantly intriguing.
Sweeping climate legislation passed, climate candidates won, and animals got important protections. Here are six of the year's highlights in climate progress, according to experts. But through it all, there was encouraging progress on climate that's worth celebrating. Peter B. de Menocal, president of the Woods Hole Oceanographic Institution, told Insider that the event featured the first-ever Ocean Pavilion. "I want to invite other Indigenous communities in Ecuador and the world to join these collective fights happening in Amazonia," Lucitante previously told Insider.
