Four researchers came together to propose the addition of six novel particles to tackle five enduring issues within the current Standard Model Theory. This new proposed model, detailed in APS Physics, is named SMASH for “Standard Model Axion See-saw Higgs portal inflation.” The team proposed that particles rho and axion could explain inflation and dark matter respectively, along with three heavy right-handed neutrinos.

With these findings, the researchers hope to answer the following questions about the Standard Model:

NASA Administrator Jim Bridenstine reflects on the former president’s contributions to our space program by saying, “The President noted it was humanity’s destiny to explore, and America’s destiny to lead. We salute this great American leader, who challenged us to chart a course for the future to benefit all humanity.”

  • Fox and the producers of “Cosmos” have opened an investigation into multiple sexual misconduct claims against the show’s host, astronomer Neil deGrasse Tyson.
  • Dr. Katelyn N. Allers of Bucknell University claimed deGrasse Tyson groped her at an event in 2009.
  • Another woman, Ashley Watson, claimed that she quit her former job as Tyson’s assistant in response to repeated inappropriate sexual advances he made toward her.
  • Both allegations came to light roughly a year after musician Tchiya Amet claimed that Tyson raped her when they were both graduate students.

Fox and the producers of the television series “Cosmos” have opened an investigation into multiple sexual misconduct claims against the show’s host, Neil deGrasse Tyson. The move follows a report on the website Patheos in which two women accused Tyson of inappropriate sexual behavior.

“The credo at the heart of ‘Cosmos’ is to follow the evidence wherever it leads,” the producers said in a joint statement. “The producers of ‘Cosmos’ can do no less in this situation. We are committed to a thorough investigation of this matter and to act accordingly as soon as it is concluded.”

I hope you’re not all partied out after the InSight lander’s successful touchdown on Mars this week, because there’s another big spaceflight event just around the corner.

NASA’s OSIRIS-REx probe will officially arrive at the near-Earth asteroid Bennu at about 12 p.m. EST (1700 GMT) on Monday (Dec. 3), ending a 27-month deep-space chase. NASA will mark the occasion with a special webcast event from 11:45 a.m. to 12:15 p.m. EST (1645 to 1715 GMT), which you can watch live here at Space.com, courtesy of NASA TV.

The space agency will also air an “arrival preview program” at 11:15 a.m. EST (1615 GMT). You can catch that here at Space.com as well. [OSIRIS-REx: NASA’s Asteroid Sample-Return Mission in Pictures].

There’s a new form of matter out there and it’s called a supersolid. Born in the labs of researchers from the Massachusetts Institute of Technology (MIT), this new matter is seemingly a contradiction. The supersolid combines properties of solids and superfluids — or fluids with zero viscosity, thereby flowing without losing kinetic energy. Supersolids have previously been predicted by physicists, but have not been observed in a lab until now.

“It is counterintuitive to have a material which combines superfluidity and solidity,” says team leader Wolfgang Ketterle, the John D. MacArthur Professor of Physics at MIT and 2001 Noble laureate. “If your coffee was superfluid and you stirred it, it would continue to spin around forever.” Their research was published in the journal Nature.

To develop this seemingly contradictory form of matter, Ketterle’s team manipulated the motion of atoms in a superfluid state of dilute gas, called a Bose-Einstein condensate, or BEC. Ketterle co-discovered BEC, which won him his Noble prize in physics. “The challenge was now to add something to the BEC to make sure it developed a shape or form beyond the shape of the ‘atom trap,’ which is the defining characteristic of a solid,” Ketterle explained.
