Colossal squid filmed in deep ocean for the first time ever
In the darkness of the South Atlantic Ocean, researchers captured for the first time footage of a live colossal squid (Mesonychoteuthis hamiltoni). And while the elusive creature is known for its size—reaching lengths of 23 feet—this one is a baby and only one foot long.
In 1925, fisherman first found the remains of a colossal squid inside a sperm whale. Over the next century, only eight adult colossal squids have been found, all postmortem.
'It's exciting to see the first in situ footage of a juvenile colossal and humbling to think that they have no idea that humans exist,' Dr. Kat Bolstad of the Auckland University of Technology, an independent scientific expert who was consulted to verify the footage, said in a statement. 'For 100 years, we have mainly encountered them as prey remains in whale and seabird stomachs and as predators of harvested toothfish.'
A team of scientists captured the groundbreaking footage using a remotely operated vehicle (ROV) on March 9 while onboard the Schmidt Ocean Institute's research vessel Falkor (too). The 35-day expedition was part of an Ocean Census expedition searching for new marine life, and a collaboration between Schmidt Ocean Institute, the Nippon Foundation-Nekton Ocean Census, and GoSouth, a joint project between the University of Plymouth (UK), GEOMAR Helmholtz Centre for Ocean Research (Germany), and the British Antarctic Survey.
The juvenile squid appears translucent as it slices through the water, but when it ages, it will become less see-through as its muscles thicken. Its large eyes—the largest of any known creature—can also be seen in the footage. Bolstad explains that the reason the squids have been so hard to find with cameras could be because of the sensitivity of their enormous eyes. 'Most of our deep-sea exploration equipment is large, noisy and uses bright lights if we are trying to film animals,' Bolsted writes on The Conversation.
Dr. Jyotika Virmani, Schmidt Ocean Institute's executive director, summed up the breakthrough: 'These unforgettable moments continue to remind us that the Ocean is brimming with mysteries yet to be solved,'

Scientists make chilling discovery hidden deep within centuries-old ice cores: 'We need to raise the alarm'
A group of scientists is in a race against time in the Arctic. Valuable climate data is at risk of disappearing as our overheating planet melts glacier ice. Our warming world is melting glaciers and ice sheets, and crucial climate data is vanishing along with them, reported Carbon Brief. A team of scientists is studying the Blombstrandbreen glacier, located approximately halfway between mainland Norway and the North Pole, to determine the degree of damage caused by meltwater penetrating deep into the ice. "If you imagine an ice core like a book containing important information, what is happening is almost like someone has spilled a cup of tea all over the pages," Dorothea Moser, a British Antarctic Survey scientist, told Carbon Brief. "The melting of ice cores is a big issue and we need to raise the alarm — but we also can't give up on them completely yet." The ice cores that are extracted from glaciers such as Blombstrandbreen hold vital information that helps scientists reconstruct past climate conditions. Air bubbles trapped inside the ice can provide scientists with a glimpse into the past, as the gases present when the ice formed are stored within them. Scientists can glean valuable information from this type of "proxy data." "Paleoclimatologists gather proxy data from natural recorders of climate variability such as corals, pollen, ice cores, tree rings, caves, pack rat middens, ocean and lake sediments, and historical data," according to the National Oceanic and Atmospheric Administration. "By analyzing records taken from these and other proxy sources, scientists can extend our understanding of climate far beyond the instrumental record." The Arctic is warming at a rate nearly four times faster than Earth's average. "Arctic amplification" means the region's ice is rapidly melting and putting crucial climate data at risk of being lost forever. On the opposite side of the Earth, scientists say some of Antarctica's glaciers may have entered a phase of irreversible melting. Arctic ice melt is a danger to our communities for a number of reasons. It can contribute to higher tides during extreme weather events, increase the spread of disease, and disrupt food chains and marine ecosystems. Moving away from dirty energy sources that release heat-trapping gases into our atmosphere is crucial to cooling our planet. There have been some promising breakthroughs in cleaner, renewable energy sources such as solar energy. Japanese researchers have developed the world's highest-efficiency solar cells, which offer the added benefit of being more eco-friendly. Going solar with a battery system not only strengthens your home's resilience to extreme weather and outages; it also drastically cuts your reliance on dirty energy and can bring your energy costs down to at or near $0. With EnergySage, you can easily compare quotes from vetted installers and save up to $10,000 in the process. Learning about critical climate issues and sharing that information with friends and family can help bring attention to things such as vanishing glaciers and ice sheets. It could inspire them to take action and fight for the future of our planet. Do you think America has a plastic waste problem?

Scientist Who Discovered Hole in Ozone Layer Reveals 'Fear For Coming Generations'
Based on facts, either observed and verified firsthand by the reporter, or reported and verified from knowledgeable sources. Newsweek AI is in beta. Translations may contain inaccuracies—please refer to the original content. One of the scientists who discovered the hole in the ozone layer 40 years ago is proud of his work, but he now has major concerns about a new existential crisis: the looming threat of climate change. Jonathan Shanklin, a meteorologist and an emeritus fellow for the British Antarctic Survey (BAS), helped discover the hole in the ozone layer in 1985 along with Joe Farman and Brian G. Gardiner. In a statement released May 13, Dominic Hodgson, director of science at the BAS, dubbed it "one of the most important environmental discoveries of the 20th century".

Photo by Алексей Филатов / Getty Images In an email to Newsweek, Shanklin said that 40 years after the discovery, he was most proud "that the observations were correct and did indicate that the ozone layer above Antarctica was in trouble". The scientists' discovery led to quick international action, and according to the World Economic Forum, the ozone layer is "on a path to recovery". That recovery is in large part due to the Montreal Protocol, an agreement signed by a record number of countries in 1987 banning the use of chlorofluorocarbons (CFCs). Banning CFCs, however, was straightforward compared to the looming crisis of climate change. 'Blighted by the consequences' "Stopping the release of chemicals harmful to the ozone layer was relatively straightforward—manufacturers had (or could design) alternatives that they could supply and there was no requirement for a change in personal lifestyle," Shanklin told Newsweek. The problem with climate change, according to Shanklin, is "an economic model that does not stand up to scientific scrutiny". "I personally fear for coming generations whose lives are going to be blighted by the consequences of climate change," Shanklin added. "The evidence is very strong and politicians need to act upon it." Shanklin said that our current economic model makes two incorrect assumptions. The first is that resources are infinite, and the second is that using them has no consequences. "It is blindingly obvious that natural resources are not infinite, and is becoming increasingly obvious in the form of all the crises that affect us (ozone, climate, biodiversity, plastic pollution etc.) that using natural resources does have consequences and that the cost of these needs to be included in the model," Shanklin noted. 'Essentially a story of personal greed' Having once inspired international action with a scientific discovery, Shanklin said he believes that one important lesson was the importance of what a potential crisis is called. "An ozone hole was clearly a problem, whereas climate change or greenhouse warming can sound quite attractive to some," he said. He added, "Another lesson is that it is important to have political leaders who understand science," noting that former British Prime Minister Margaret Thatcher had trained as a chemist. Finally, he stressed the importance of seeing how each crisis is interconnected—that fixing each one in isolation is impossible. "The underlying linkage is essentially a story of personal greed and a lack of altruism," he said. "Collectively, we need to think of others and future generations."
