Summary List Placement SpaceX says early tests of its rapidly growing fleet of internet-providing satellites are yielding promising results. Internal tests of a beta version of internet service from the company's Starlink project show "super low latency and download speeds greater than 100 [megabits] per second," Kate Tice, a SpaceX senior certification engineer, said during a live broadcast of a Starlink launch on Thursday. ...

Greenland's ice sheet may have passed a point of no return, setting it on an irreversible path to disappearance, according to researchers at Ohio State University.  Snowfall can no longer replenish the ice lost as Greenland's glaciers retreat, so it will keep melting and cause catastrophic sea-level rise, even if global temperatures stop rising. The climate crisis could bring about other tipping points in...

The US Centers for Disease Control and Prevention recently updated its coronavirus quarantine guidelines to make an exception for people who have had the virus in the last three months.  The CDC released a statement on Friday clarifying that it was not saying those people have immunity against reinfection — instead, they're less likely to be infectious. Growing research shows that people who recover...

NASA astronauts Bob Behnken and Doug Hurley, tucked inside SpaceX's Crew Dragon spaceship, survived a fiery plunge through...

The US has broken records for daily coronavirus case counts five times in the last 12 days. Deaths have not surged, however, possibly because the virus is mostly spreading among young people. COVID-19 progresses over weeks, though, so death tolls may still start climbing. Although various databases offer differing daily US case counts, they tell the same story overall: Cases skyrocketed after states reopened....

The 2020 hurricane season has already broken a record, and it's only day three. Tropical Storm Cristobal, the third named storm in the season, arrived earlier than any other third named storm in history. NOAA forecasts six to 10 hurricanes in total for the season. The odds that a cyclone will become a major hurricane have increased 8% each decade for the last 40...

Astronomers have discovered a black hole just 1,000 light-years from our solar system — the closest ever found. Usually scientists find black holes by detecting the X-rays they emit, but scientists stumbled upon this one when they observed two stars orbiting each other and realized a massive, invisible object was in the mix. There could be millions of other silent black holes like this...

Epidemiological models increasingly show that lifting lockdowns too early can lead to tens of thousands of preventable COVID-19 deaths. Without maintaining strong social-distancing measures, the US death toll could breach 100,000 by mid-May. Georgia reopened more quickly than any other state, and that could cost it thousands of lives. Visit Business Insider's homepage for more stories. After weeks of economically devastating lockdowns, state and...

A crucial metric called R0, pronounced R-naught, represents how many people an average person with a virus infects. The coronavirus has an R0 of roughly 2 to 2.5, meaning that each new person spreads the disease to about 2.2 people on average. That makes COVID-19 more contagious than the seasonal flu. But a disease's R0 isn't fixed — it can decrease with the right...

On Wednesday, Dr. Anthony Fauci discussed his playbook for preparing the US for potential future waves of COVID-19 infections, which could come after lockdowns lift or in the fall. Fauci said the US should develop its capacity for widespread testing, contact tracing, and case isolation — "the things that were not in place in January." Antibody testing could help experts understand how many people...
