Physicists replicate earliest days of the universe in super-chilled helium

Physicists replicate earliest days of the universe in super-chilled helium

Science
Jan. 16 (UPI) -- Scientists have for the first time triggered quantum structures long-predicted by cosmologists. Researchers at Aalto University in Denmark observed "walls bound by strings" in superfluid helium-3. The breakthrough could allows scientists to better understand what the universe looked like in its earliest days, as it quickly cooled in the wake of the Big Bang. Helium is unique in it's ability to remain a fluid even at cryogenic temperatures. When supercooled, helium becomes a superfluid, which means it boasts zero viscosity. Superfluids can flow forever without losing energy. When trapped inside a nanostructure, superfluid phases of the isotope helium-3 can help scientists study unusual quantum structures called half-quantum vortices. The movement of helium inside these vor...

Weather: UK experiencing hotter days and 'tropical nights' – Met Office

Science
The UK has experienced more weather extremes over the last 10 years when compared with previous decades, a Met Office report has said. The hottest days have become almost 1C hotter, warm spells have increased, while the coldest days are not as cold. The number of so-called tropical nights - when temperatures stay above 20C - is increasing. The Met Office says these changes are consistent with warming driven by human activities. The new study compares UK weather data from the period 1961-1990 with the 10 years between 2008 and 2017.

BSEE: One-third of Gulf oil output remains 'shut-in' two days after Michael

Business
Oct. 12 (UPI) -- Some hydrocarbon producers that evacuated facilities and suspended extraction in the Gulf of Mexico ahead of Hurricane Michael had not yet fully restarted operations as of noon on Friday. As much as 32 percent of the area's crude oil production and 13 percent of the natural gas production still "shut-in," a U.S. agency said Friday. The volumes indicated in the Friday report by the Bureau of Safety and Environmental Enforcement corresponding to the 'shut-in' production were 550,313 barrels per day of crude oil and 334 million cubic feet per day of natural gas. As of 11:30 a.m. EST on Friday, personnel from only nine production platforms, or just over one percent of the total 687 manned platforms, remained evacuated. "The production percentages are calculated using informa...

Cryptocurrencies suffer $18 billion drop in value over three days

Finance
This was a tough week for cryptocurrencies. Bitcoin finally began to stabilize Friday, but not before the total cryptocurrency market lost $ 18 billion of its already waning value in the course of a few days. The world's largest and most widely owned digital asset began its slide Wednesday evening and fell below $ 6,200 for the first time in a month, according to data from CoinDesk. Bitcoin was mostly stable in the $ 6,200 range as of Friday afternoon but had kicked this week off well above $ 6,500, ending the week about 5 percent lower. Other cryptoc...

Survivor pulled out two days after ferry disaster

World
A survivor has been pulled out of a capsized ferry on Lake Victoria in Tanzania, two days after the boat sunk with as many as 300 people on board. The man, an engineer, had shut himself in a "special room" sealed with enough air to allow him to stay alive, according to reports from local member of parliament Joseph Mkundi.Divers rescued him from inside the MV Nyerere after hearing sounds that indicated signs of life. 0:54 Video: Ferry capsizes close to Tanzania pier ...
