Satellite constellations: Astronomers warn of threat to view of Universe

Science
Astronomers are warning that their view of the Universe could be under threat. From next week, a campaign to launch thousands of new satellites will begin in earnest, offering high-speed internet access from space.But the first fleets of these spacecraft, which have already been sent into orbit by US company SpaceX, are affecting images of the night sky.They are appearing as bright white streaks, so dazzling that they are competing with the stars.Scientists are worried that future "mega-constellations" of satellites could obscure images from optical telescopes and interfere with radio astronomy observations.Dr Dave Clements, an astrophysicist from Imperial College London, told BBC News: "The night sky is a commons - and what we h...

Instagram to warn users over ‘bullying’ language in their captions

Technology
Instagram will start warning users when it detects potentially bullying language in its captions.The app said it will use artificial intelligence to spot possibly harmful language and give users the opportunity to reconsider it before sharing. A similar feature was introduced earlier this year which warned users if it thought their comments on other people's posts contained bullying or offensive language.If the AI spots something, a message will appear telling the user the caption looks similar to others that have previously been reported and gives them the option to edit it, learn about why it was flagged, or share it anyway.It comes amid criticism that Facebook-owned Instagram has not acted quickly enough to remove abusive and potentially dangerous content from the platform. ...

U.S. health officials warn of eastern equine encephalitis outbreak

Nov. 21 (UPI) -- An old disease transmitted by mosquitoes called eastern equine encephalitis has reared its head in eight U.S. states so far in 2019, but health officials emphasize there's no need to bug out. In a commentary published Thursday in the New England Journal of Medicine, officials from the National Institute of Allergy and Infectious Diseases noted that, as of Nov 12, there have been 36 confirmed cases of eastern equine encephalitis, or EEE, this year. In all, 14 of these cases were fatal. "Although EEE isn't a major threat at this time, the public needs to be aware that it's out there," NIAID Director Anthony S. Fauci, MD, told UPI. To date, cases of EEE have been confirmed in Connecticut, Indiana, Massachusetts, Michigan, North Carolina, New Jersey, Rhode Island and Tenness...

Environmentalists warn Trump ‘weakening’ endangered species protections

Science
The US federal government has announced an overhaul of the way it enforces the Endangered Species Act, a law credited with preventing countless extinctions.Trump officials say the new plan will reduce regulations, but environmental groups warn it will "crash a bulldozer" through the landmark 1973 legislation.The plan removes automatic protections for threatened species and allows economic factors to be considered.Critics say the new rules will speed extinction for vulnerable wildlife.Ten state attorneys general have announced plans to sue over the new regulation.The Endangered Species Act, which Republican President Richard Nixon signed into law in 1973, protects more than 1,600 plant and animals species today, and is credited wi...
Stop abusing land, scientists warn

Stop abusing land, scientists warn

Science
Scientists are to deliver a stark condemnation of the damage being done to the land surface of the planet.Human activities have led to the degrading of soils, expanded deserts, felled forests, driven out wildlife, and drained peatlands, they will say.In the process, land has been turned from an asset that combats climate change into a major source of carbon.The scientists will say this land abuse must be stopped to avoid catastrophic climate heating.UK's 10 warmest years all occurred since 2002Climate change: Where we are in seven chartsWhat is climate change?How can the land protect us from climate change?Uncultivated land covered with vegetation protects us from overheating because the plants absorb the warming gas CO2 from the...
