Shadowy hints of dark matter’s true nature are set to be boosted by a new particle and gamma-ray detector being launched into orbit.
A supercomputer simulation of a mere 10 milliseconds in the collapse of a massive star into a neutron star proves that these catastrophic events, often called hypernovae, can generate the enormous magnetic fields needed to explode the star and fire off bursts of gamma rays visible halfway across the universe.
The results of the simulation, published online Nov. 30 in advance of publication in the journal Nature, demonstrate that as a rotating star collapses, the star and its attached magnetic field spin faster and faster, forming a dynamo that revs the magnetic field to a million billion times the magnetic field of Earth.
A field this strong is sufficient to focus and accelerate gas along the rotation axis of the star, creating two jets that ultimately can produce oppositely directed blasts of highly energetic gamma rays.
Amazon says drones can deliver packages weighing up to 5 pounds within 30 minutes.
“In time, there will be a whole family of Amazon drones,” says narrator Jeremy Clarkson, the former BBC “Top Gear” cohost who is working on a similar show for Amazon. “Different designs for different environments.”

As the line between tabloid media and mainstream media becomes more diffuse, news items such as Ebola, pit bulls, Deflategate, and Donald Trump can frequently generate a cocktail of public panic, scrutiny, and scorn before the news cycle moves on to the next sensational headline. According to Robotics Expert and self-proclaimed “Robot Psychiatrist” Dr. Joanne Pransky, the same phenomenon has happened in robotics, which can shape public perception and, by extension, the future development of robots and AI.
“The challenge, since robotics is just starting to come into the mainstream, is that most of the country is ignorant. So, if you believe what you read, then I think people have a very negative and inaccurate picture (of robotics),” Pransky said. “I spend a lot of time bashing negative headlines, such as ‘ROBOT KILLS HUMAN,’ when actually the human killed himself by not following proper safety standards. A lot of things are publicized about robotics, but there’s nothing about the robot in the article. It leads people on the wrong path.”

Researchers from North Carolina State University have discovered a new phase of solid carbon, called Q-carbon, which is distinct from the known phases of graphite and diamond. They have also developed a technique for using Q-carbon to make diamond-related structures at room temperature and at ambient atmospheric pressure in air.
Phases are distinct forms of the same material. Graphite is one of the solid phases of carbon; diamond is another.
“We’ve now created a third solid phase of carbon,” says Jay Narayan, the John C. Fan Distinguished Chair Professor of Materials Science and Engineering at NC State and lead author of three papers describing the work. “The only place it may be found in the natural world would be possibly in the core of some planets.”
