Sea cucumber inspires new plastic for body armor, brain implants
Sea cucumbers’ skin is usually supple, allowing them to slide through narrow spaces between rocks and corals; when touched, however, a defensive reaction makes their skin go rigid in seconds, thanks to enzymes that bind protein fibers together; researchers apply this process to clothing, creating garments which switch stiffness in response to a pulse of electricity

Global Temperatures Rising More Quickly, Warns UN
Sea-level rise, ice loss, extreme weather and other effects of climate change are increasing, according to the United Nations’ weather agency. The period from 2015 to the end of 2019 is likely to be the warmest five-year period on record globally, the World Meteorological Organization (WMO) said. Last year there was the largest number of tropical cyclones of any year since 2000 and large parts of Africa, central America, Brazil, the Caribbean and Australia have experienced more frequent droughts since 2015.
Humans “Extinct by 2100” as Intelligent Life Annihilates Itself Says Oxford Prof
There is almost a one-in-five chance that humans will be wiped out before this century is over, according to an Oxford University department. The overall probability — or “existential risk” — of human extinction by 2100 is worryingly high, at 19 percent, Oxford University’s Future of Humanity Institute has calculated. Nick Bostrom, director of the Institute, notes that we should worry about the fact that aliens have not yet visited planet Earth: With billions of stars in our galaxy, it is proposed that statistically there is a very high chance of an alien race existing which has mastered space travel. But we have never found any evidence for interstellar tourists. This intriguing contradiction is known as the Fermi Paradox. Bostrom says that the fact that we have so far failed to discover another intelligent existence in space may mean that other intelligent races on other planets, if they had ever existed, may have doomed themselves to extinction by their own advanced technologies.
Arctic Ice Is Melting Faster Than Expected. These Scientists Have a Radical Idea to Save It.
glaciers, polar land, and sea ice are rapidly melting, much faster than many scientists expected, as the Intergovernmental Panel on Climate Change’s (IPCC) report on oceans and the cryosphere released Wednesday reiterated. During a five-day heat wave this summer, Greenland lost more than 60 billion tons of ice, including the biggest loss in a 24-hour period since record-keeping began. Recent projections warn that Arctic summers could be nearly ice-free in 10 to 40 years. These grim warnings have prompted more researchers to apply technological solutions that intervene in the earth’s climate systems to slow the impacts of global warming, also known as “geoengineering.”
Designing the Coastal City of the Future
Boston is situated along the Gulf of Maine, which is warming faster than 99 percent of the ocean due, in part, to changing sea patterns from melting ice in Greenland and the Arctic Ocean. Coupled with increased heat and precipitation, the rising sea level is threatening the low-lying city, much of which was built on landfill over the past 300 years along a 50-square-mile harbor. To save the 685,000-person city, the local government is calling on architects to help implement one of the most ambitious municipal resiliency plans in the United States: Climate Ready Boston. Launched in 2016 by Mayor Martin J. Walsh, Climate Ready Boston is an initiative to prepare the city for the long-term impacts of climate change.
Mysterious Case of the Vanishing UFOs
All over the rest of the world UFOs are in sharp decline, and may soon disappear altogether. People are simply not spotting unidentified spacecraft like they used to. Alien abductions are at an all-time low. UFO-spotting organizations are closing down. Since 2014 alien sightings have halved. The chances of anything coming from Mars are a million to one, and dropping. “Where have all the UFOs gone?” Ben Macintyre asks in The Times, noting that “The recent drastic worldwide decline of unexplained phenomena is one of the odder unexplained phenomena of modern times.”
AI Could Be a Disaster for Humanity. A Top Computer Scientist Thinks He Has the Solution.
Stuart Russell is a leading AI researcher who co-authored the top textbook on the topic. He has also, for the last several years, been warning that his field has the potential to go catastrophically wrong. In a new book, Human Compatible, he explains how. AI systems, he notes, are evaluated by how good they are at achieving their objective: winning video games, writing humanlike text, solving puzzles. If they hit on a strategy that fits that objective, they will run with it, without explicit human instruction to do so.
