13,000-year-old Tusk reveals life of 'Fred', a juggernaut who died in battle

A mounted skeleton of the Buesching mastodon.Photo: Eric Bronson, Michigan Photography Researchers have detailed the grisly life and death of a male behemoth that died 13,200 years ago by examining the chemical makeup of one of its tusks. The defense revealed that the behemoth grew up in the Great Lakes region and later in life … Read more

SpaceX Polaris Dawn astronauts train for orbital mission

SpaceX Polaris Dawn astronauts train for orbital mission

The crew of the privately funded Polaris program’s first mission are reaching new heights to prepare for their record-breaking SpaceX flight later this year. A mission profile, estimated launch schedule, and crew update were recently shared on the Polaris website, a dual effort between SpaceX and billionaire tech entrepreneur Jared Isaacman. Isaacman funded and commanded … Read more

Fastest growing black hole in past 9 billion years may have been found, say Australian astronomers | Space

Astronomers believe they have discovered the fastest growing black hole in the past 9 billion years. The supermassive black hole consumes the equivalent of an Earth every second and has the mass of 3 billion suns, they estimate. Scientists have discovered an extremely bright quasar, a luminous object powered by a supermassive black hole, using … Read more

As the Large Hadron Collider ramps up, physicists’ hopes soar

As the Large Hadron Collider ramps up, physicists' hopes soar

In April, scientists at the European Center for Nuclear Research, or CERN, near Geneva, again fired their cosmic cannon, the Large Hadron Collider. After a three-year shutdown for repairs and upgrades, the collider has resumed firing protons — the bare innards of hydrogen atoms — around its 17-mile underground electromagnetic racetrack. In early July, the … Read more

A rogue black hole roaming our galaxy may have just been confirmed

A rogue black hole roaming our galaxy may have just been confirmed

The first detection of what appears to be a rogue black hole drifting through the Milky Way, revealed earlier this year, has just received significant validation. A second team of scientists, conducting a separate and independent analysis, came to almost the same conclusion, adding weight to the idea that we have potentially identified a rogue … Read more

Ten years after the Higgs, physicists face the nightmare of finding nothing else | Science

Ten years ago, particle physicists rocked the world. On July 4, 2012, 6,000 researchers working with the world’s largest atom destroyer, the Large Hadron Collider (LHC) at the European particle physics laboratory, CERN, announced that they had discovered the Higgs boson, a massive, fleeting particle, key to their obscure explanation of how other fundamental particles … Read more
