A 400000-year-old skull fragment found in Portugal points to mystery people
A skull fragment from nearly half a million years ago points to the possibility of a previously unknown species of early humans.THE discovery of a skull fragment from nearly half a million years ago points to a previously unknown subspecies of early humans and offers tantalising hints about a possible ancestor of the Neanderthals, scientists say.The 400,000-year-old fossil was unearthed from a cave site in Portugal in 2014 using ancient stone hand axes, and marks the oldest human cranium fossil ..>> view originalEnd of the Great Barrier Reef? More than 90 per cent of Earth's coral reefs 'dead by 2050'
And the remaining reefs will also vanish unless something is done immediately to protect them. Biologists from across the globe made the stark warning after the worst global 'bleaching' event on record, which peaked between 2015 and last year, but is still going on now. Bleaching occurs when water temperatures rise by only a few degrees, causing the coral to expel the colourful, nourishing algae and leaving it's white skeleton fatally exposed to the elements.Coral is also sensitive to over-fishi..>> view originalWelcome to Pan: Saturn's Ravioli-Shaped Moon

The universe served up a piece of astro-pareidolia last week, when humanity got its first closeup look at Saturn's tiny moon Pan. Appropriately named after the half-man, half-goat satyr from Greek mythology, Pan is nestled in the Encke (pronounced EN-key) Gap within Saturn's A ring.

Consciousness is the most important quality of a human being, but scientists have struggled for millennia to explain it - where does it come from, and how does it arise? We've seen studies try to pinpoint the physical location of consciousness in the brain, and one physicist has even proposed that it's a new state of matter. And now scientists want the public to solve a chess problem that computers find impossible so we can figure out what separates our minds from machines.

Space Exploration Technologies, or SpaceX, has delayed the launch of a rocket set to carry a commercial communications satellite into orbit, because of high winds at its Florida launch site.Wind gusts of up to 40km/h at NASA's Kennedy Space Centre in Florida forced SpaceX to scrub the launch of the Falcon 9 rocket that was to have put into orbit EchoStar XXIII, a commercial communications satellite for EchoStar Corporation, the privately owned company said on Twitter."Standing down due to high w..>> view originalHumans to blame for bulk of Arctic sea ice loss, study finds
Human activity is overwhelming contributing to the demise of Arctic ice, a new study has found. Picture: Corey WilsonNATURAL changes in the environment are responsible for about 40 per cent of Arctic sea ice loss, while humans are to blame for the rest, a climate study said this week.The paper, based on model simulations of different climate conditions, was a rare attempt to quantify the relative contributions of humans and nature to the dramatic decline and could have a major impact on future r..>> view originalHumpback Whales Are Forming Mysterious 'Super-Groups', and No One Can Explain It
Humpback whales are known for being the loners of the sea - while they tend to migrate, feed, and mate in groups, they spend much of their existence in solitude, or in small, short-lived groups of up to seven individuals. But something could be brewing in our oceans, because scientists are reporting 22 separate instances of humpback 'super-groups' that defy explanation - never-before-seen groups of 20 to 200 whales all appearing off the southwest coast of South Africa in recent years.

The death of mangrove forests stretched over 1000 kilometres of Australia's northern coast a year ago has been blamed on extreme conditions including record temperatures.About 7400 hectares of mangroves strung along the Gulf of Carpentaria died in a single month in early 2016 because of the unusual warmth, a prolonged drought and an El Nino that reduced local sea levels by about 20 centimetres, said Norman Duke, head of the Mangrove Research hub at James Cook University.

New York, March 14 (IANS) Researchers have found evidence of a white dwarf star orbiting a likely black hole at a distance of only 961,000 km -- just about 2.5 times the distance between the Earth and the Moon.In a tightest orbital dance ever witnessed for a black hole and a companion star, the star whips around the black hole at an astonishing speed -- about two orbits an hour, said the study published in the journal Monthly Notices of the Royal Astronomical Society."This white dwarf is so clos..>> view original
