Coffee Is Coffee Is "Headed for Extinction" and We Need to Sit Down
- January 19, 2019

Most popular coffee blends derive from either the Arabica or Robusta bean, but as Somini Sengupta explains for The New York Times , these strains are just two of the world's 124 wild coffee species . Worldwide coffee chain Starbucks, which uses all Arabica beans, failed to respond to a request for comment. Using computer modelling they were able to project how a changing climate would affect the species in Ethiopia, showing that the number of locations where Arabica grows could ... (more...)
Cassini Reveals the Surprisingly Young Age of Saturn's Rings Cassini Reveals the Surprisingly Young Age of Saturn's Rings
- January 19, 2019

The sixth planet from the Sun formed about 4.5 billion years ago, along with the rest of the planets in our solar system, and spent the bulk of its existence without the characteristic rings it is known for today. Additional analyses suggest the methane rain fell across a relatively pebble-like surface, she said. "The discovery of deeply rotating layers is a surprising revelation about the internal structure of the planet", Cassini project scientist Linda Spilker at NASA's Jet Propulsion ... (more...)

If confirmed, Wheeler would continue to push the Trump administration's deregulatory and pro-fossil fuels agenda without the constant criticism over alleged mismanagement that plagued Wheeler's predecessor Scott Pruitt . "I consider it a huge issue that has to be addressed globally". Wheeler told lawmakers that he had yet to read a massive government climate-change report released late previous year that emphasized man-made climate change was already underway. (more...)

That's because temperatures drop to -150 degress Celsius during lunar nights on the moon , and according to Xie Gengxin, chief designer of the experiment, life inside the canister would simply not survive those conditions. The whole experiment is contained within an 18 cm tall, 3 kg canister that was designed by 28 Chinese universities, the BBC said . Along with a number of sophisticated scientific instruments, the mission's lunar lander carried a sealed container, the lunar mini ... (more...)

Moon base: China envisions moon base after far-side success Moon base: China envisions moon base after far-side success
- January 16, 2019

China accomplished a historic feat this year by landing a robotic mission on the far side of the moon. So was a data collaboration with NASA , the first cooperation since a 2011 law banned such activity without congressional approval. The mission demonstrates China's growing ambitions as a space power to rival Russian Federation, the European Union and the U.S. China set up a relay satellite in May to receive communication from Chang'e 4 .

Antarctica ice melting increased by 280% in last 16 years, study says Antarctica ice melting increased by 280% in last 16 years, study says
- January 15, 2019

A landmark study published in Nature in June previous year found that Antarctic ice melt had tripled since 1992, but did not show significant melting in the east. He said the big difference is that his satellite-based study found East Antarctica, which used to be considered stable, is losing 51 billion metric tonnes of ice a year. (more...)

Lead author Xiaohui Fan, from the University of Arizona, said he did not expect to find many quasars brighter than this in the entire universe. Quasars are massive celestial objects which emit huge amounts of energy. "The puzzling growth of extremely bright quasars within less than a billion years after the Big Bang might be partly a mirage". The observations also led to a determination of the mass of the black hole powering the quasar. (more...)

The cosmic event occurred in June a year ago and was picked up by telescopes in Hawaii. But the team still isn't sure exactly what The Cow is. A black hole is the most mysterious space object. Or a New View of a Supernova? Margutti and her team are using a comprehensive approach to examine "The Cow" using X-rays, hard X-rays (which are 10 times more powerful than normal X-rays), radio waves and gamma rays. (more...)

The flash, called ASASSN-14li, looked just like your typical black-hole-gravity-shredding-a-star-to-bits event, happening near the center of a host galaxy. Now he says that, given the team's results, such tidal disruption flares can be used to estimate the spin of supermassive black holes - a characteristic that has been, up until now, incredibly tricky to pin down.
