☆ Fossils reveal butterfly 'tree of life' and origins
▼ + stars: | 2023-05-17 | by ( Ashley Strickland | ) edition.cnn.com time to read: +8 min

CNN —The world’s largest butterfly tree of life is helping researchers determine where the winged insects originated when they first appeared on Earth about 100 million years ago. Scientists first uncovered in 2019 how this single shift to daytime activity served as the evolutionary turning point for all butterfly species. Together, the researchers collected DNA from nearly 2,300 species from 90 countries that represent all butterfly families. “We used multiple fossils for the study in order to calibrate particular parts of the tree,” Kawahara said. “Europe doesn’t have many butterfly species compared to other parts of the world, and the ones it does have can often be found elsewhere,” Kawahara said.

☆ Why Does This Cannibalistic Fish Keep Washing Ashore?

For hundreds of years, a strange species of fish with long fanglike teeth that eats its own kind and spends most of its time at the bottom of the ocean has somehow found its way to the shores of the West Coast. The latest appearance by a lancetfish, as the species is known, was on a beach in Oregon, state officials said Monday, prompting more speculation about why the deep-sea creature occasionally surfaces on land. Lancetfish are obscure in part because they have no commercial appeal — meaning that they don’t taste good. The silvery and gelatinous fish have a “scientific name translates to something like scaleless lizard or scaleless dragon,” and they look the part, said Elan Portner, a scientist at the Scripps Institution of Oceanography in San Diego, one place where lancetfish have been found washed ashore. Lancetfish also “migrate as far north as subarctic areas like Alaska’s Bering Sea to feed,” according to the National Oceanic and Atmospheric Administration.

Kyiv and the West accuse Russian forces of committing war crimes in occupied Ukrainian territory, which Moscow denies. Kherson, Zaporizhzhia, Luhansk and Donetsk are the four regions that Putin proclaimed annexed last September following what Ukraine said were sham referendums. Russian forces only partly control the four regions. HEAVY ARTILLERYFighting has raged in and around Bakhmut in Donetsk region for months, with Ukrainian forces holding out despite regular claims by Russia to have taken the city. "Any use of chemical, biological or nuclear weapons by Russia would be met with severe consequences," they said.

Russian Defence Ministry/Handout via REUTERSFeb 15 (Reuters) - Several Russian strategic bombers and fighter jets have been intercepted by North American air defence forces as they flew over international airspace near Alaska, the North American Aerospace Defence Command (NORAD) said. "NORAD had anticipated this Russian activity ... Two NORAD F-16 fighters intercepted the Russian aircraft," it said. Russia said on Wednesday that it had carried out several flights over international waters in recent days, including in the Bering Sea between Alaska and Russia. "Long-range aviation pilots regularly perform flights over the neutral waters of the Arctic, North Atlantic, Black Sea, Baltic Sea and Pacific Ocean," Russia's defence ministry said.

☆ US officials say getting their hands on China's spy balloon was a 'key' reason for shooting it down near a South Carolina beach

US officials say balloons have crossed over the US before as part of a wider Chinese surveillance program. The eight-day wait and the sensitivity of those bases have alarmed lawmakers, who called defense officials to Capitol Hill on Thursday to explain their handling of the incident.

The hearing was part of a series of events Thursday morning in Congress, all related to the spy balloon. In the House, a resolution condemning "the Chinese Communist Party's use of a high-altitude surveillance balloon" passed unanimously, 419-0. That vote took place shortly after House members received a classified briefing about the balloon and the recovery efforts from defense and intelligence officials.

A woman and a boy were fatally attacked by a polar bear in Alaska on Tuesday, authorities said. The bear went on a rampage in the small community of Wales, and a resident fatally shot the polar bear as it attacked the woman and the boy, the state Public Safety Department said in a dispatch. Troopers and state Department of Fish and Game officials will travel there when weather conditions allow it, according to the dispatch. Fatal polar bear attacks have been rare in Alaska’s recent history. In 1990, a polar bear killed a man farther north of Wales in the village of Point Lay.

☆ The Arctic is getting warmer and stormier, and ship traffic is increasing as ice melts

Martin Leonhard of the East Greenland Ice-Core Project (EastGRIP) operates snow blower putting a new snow floor for the winter-storage weather port tent at EastGRIP camp on August 9, 2022. EastGRIP is an international science station on the Greenland ice sheet, the second-largest ice body in the world after the Antarctic ice cap. The researchers described how hotter air temperatures, melting sea ice, shorter periods of snow cover, increased wildfire and rising levels of precipitation have forced wildlife and Indigenous people in the region to adapt. The Arctic's seven warmest years since 1900 have been the last seven years, and researchers pointed to a slew of signs that the region is undergoing a dramatic shift. Scientists also noted that maritime ship traffic is on the rise in the Arctic as sea ice declines, with the most notable increases in traffic occurring among ships traveling from the Pacific Ocean through the Bering Strait and Beaufort Sea.

Over recent years, NATO allies and Russia have scaled up military exercises in the region; Chinese and Russian warships conducted a joint exercise in the Bering Sea in September. Four Arctic experts say it would take the West at least 10 years to catch up with Russia's military in the region, if it chose to do so. "NATO is increasing its presence in the Arctic with more modern capabilities," NATO chief Jens Stoltenberg told Reuters. Now NATO and Arctic allies are changing their stance. Sweden and Finland have begun investing in surveillance and deterrence capabilities and military hardware including jets so their air forces can fight alongside Arctic NATO allies.

☆ Russia says strategic bombers flew over Pacific, Bering and Okhotsk seas

Oct 18 (Reuters) - Russia's defence ministry said on Tuesday that two of its Tu-95MS strategic bombers had conducted a flight of more than 12 hours over the Pacific Ocean, the Bering Sea and the Sea of Okhotsk. The aircraft were escorted by MiG-31 fighter planes, and refuelled while in the air, the ministry said. NATO is conducting nuclear preparedness exercises this week and has said it expects Russia to hold its own nuclear drills imminently. U.S. officials have said they expect the Russian exercises to include the test launch of ballistic missiles. Western officials are concerned about the timing of the Russian exercises but have expressed confidence in their ability to discern the difference between a Russian drill and any move by Putin to make good on his threats.

For the first time, crews in Alaska won't be braving ice and sea spray to pluck snow crab from the Bering Sea. The Alaska Department of Fish and Game canceled the snow crab season earlier this week after a catastrophic population crash of the sizable crustaceans. "It's going to be life-changing, if not career-ending, for people," said Dean Gribble Sr., a 63-year-old crab boat captain who has fished for "opies" — snow crab — since the late 1970s. In summer, many small snow crab make their habitat in a cold pool that forms on the Bering seafloor. The newspaper was the first to report the snow crab season closure.

During the US Civil War, Union and Confederate ships fought naval battles all over the world. She took 38 prizes and more than 1,000 prisoners, some of them joining the Confederate ship. From there, Shenandoah terrorized American ships in sea lanes around the Cape of Good Hope, through the Pacific, and into the Bering Sea off Alaska. Even after the Civil War was over, Shenandoah continued her Pacific rampage. The skipper just didn't believe Lee's surrender ended the war, even when American whaling captains told him so.

ANCHORAGE, Alaska — A U.S. Coast Guard ship on routine patrol in the Bering Sea came across a guided missile cruiser from China, officials said Monday. A C-130 Hercules provided air support for the Kimball from the Coast Guard station in Kodiak. The Coast Guard said Operation Frontier Sentinel guidelines call for meeting “presence with presence” when strategic competitors operate in and around U.S. waters. The Coast Guard did not immediately respond to questions about the incident from The Associated Press. In September 2021, Coast Guard cutters in the Bering Sea and North Pacific Ocean encountered Chinese ships, about 50 miles off the Aleutian Islands.

Odată construită, chinezii ar putea extinde și mai multe rețeaua lor de trenuri de mare viteză, ajungând până în fiecare colț al SUA, potrivit IFL Science. China a aprobat în 2018 primul tren de mare viteză din lume pe o rută subacvatică. Deși acest tunel subacvatic este semnificativ mai mic comparativ cu cel din Canalul Mânecii, adăugarea unui tren de mare viteză aduce noi provocări construcției. În 2020, guvernul SUA a aprobat totuși o linie de cale ferată de 2.570 de kilometri care să lege Statele Unite și Canada, din Alaska până în Alberta.
