Heavy sea ice off Newfoundland and southern Labrador has been an issue for months: it brought record-breaking numbers of polar bear visitors onshore in early March and April and since then has hampered the efforts of fisherman to get out to sea.

For the first time, China has successfully sent pairs of entangled photons from a satellite in orbit to three ground stations in the country each separated by more than 1,200-km, in a major breakthrough that opens up prospects for practical quantum communications.

A team of researchers at Sungkyunkwan University in South Korea has developed a type of adhesive patch that works under a variety of conditions including underwater. In their paper published in the journal Nature, the team describes how they studied octopus suction cups to design a better patch for human applications.

Achieving a perfect score in the 1980s video game Ms. Pac-Man is something to brag about, which is probably what Microsoft’s artificial intelligence is doing right now, assuming it actually knows how to brag.

Writing at Climate Etc., esteemed climate scientist Dr. Judith Curry has urged greater attention to the uncertainties of scientific research into global warming (aka climate change). ‘The current focus on CO2 emissions reductions risks having a massively expensive global solution that is more damaging to societies than the problem of climate change,’ she says.

Astronauts at the International Space Station released Aalto-2 into orbit on 25 May. The first satellite signal was detected from Japan on the same day, and later that evening the satellite had already made contact with the Otaniemi ground station.

When Captain James Cook and the botanist Sir Joseph Banks navigated Australia’s Great Barrier Reef (GBR) in the 1770s they described blooms of “sea sawdust” we now know to be the cyanobacterium Trichodesmium.

Almost certainly yes—though not an identical twin. And so did every other sunlike star in the universe, according to a new analysis by a theoretical physicist from UC Berkeley and a radio astronomer from the Smithsonian Astrophysical Observatory at Harvard University.

Facebook has started deploying its artificial intelligence capabilities to help combat terrorists’ use of its service.

NASA’s Wide-field Infrared Survey Explore telescope has offered astronomers a detailed view of the star factory inside the Orion Nebula, one of the most famous and oft-photographed star-birthing clouds in the cosmos.

Chinese scientists claim they will attempt to grow potatoes on the moon in 2018, according to state-run media.

The West Antarctic Ice Sheet, a landbound mass of ice larger than Mexico, experienced substantial surface melt through the austral summer of 2015-2016 during one of the largest El Niño events of the past 50 years, according to scientists who had been conducting the first comprehensive atmospheric measurements in the region since the 1960s.

China today successfully launched its first X-ray space telescope to help scientists study the evolution of black holes, strong magnetic fields, and gamma-ray bursts.

Asteroid impacts pose such a huge threat to humanity that scientists are considering “backing-up” life on Earth in secure bunkers, according to an Australian robotics professor.

Hundreds of built and proposed hydroelectric dams may significantly harm life in and around the Amazon by trapping the flow of rich nutrients and modifying the climate from Central America to the Gulf of Mexico.

Alien species are a global problem, but they’re a particular headache in certain hotspots of the world.
