The first radio burst discovered in the Milky Way is now repeating as it travels from a magnetar – a neutron star with a strong magnetic field – 32,616 light-years away.

The initial flash of energy was first detected in April and scientist have identified two more, confirming fast radio bursts ‘are emitted by magnetars at cosmological distances.’

Elon Musk’s SpaceX would like to further expanded testing of its Starlink satellite internet by connecting the network to aircraft.

SpaceX would like to further expand testing of its Starlink satellite internet by connecting the network to aircraft, the company revealed in a recent request to the Federal Communications Commission.

Elon Musk’s space company on Nov. 6 asked the FCC if SpaceX could add Starlink user terminals “on a Gulfstream jet for a period of up to two years.”

Startup Cerebras benchmarked its pint-sized computer against 16,000 Xeon cores in the DoE’s Joule supercomputer on a problem of computational fluid dynamics.

That is a bit odd o.o

A woman found a massive tooth the size of her palm sticking out from the sand on a South Carolina beach, believed to be from a prehistoric megalodon shark.

Researchers warn that official figures underestimate the pandemic’s real death toll, which could more than triple if the virus is allowed to spread unchecked.

Physicists have discovered a special kind of particle can exist around a pair of black holes in a similar way as an electron can exist around a pair of hydrogen atoms — the first example of a “gravitational molecule.”

For over a decade, theoretical physicists have predicted that the van Hove singularity of graphene could be associated with different exotic phases of matter, the most notable of which is chiral superconductivity.

A van Hove singularity is essentially a non-smooth point in the density of states (DOS) of a crystalline solid. When graphene reaches or is close to this specific energy level, a flat band develops in its electronic structure that can occupy an exceptionally large number of electrons. This leads to strong many-body interactions that promote or enable the existence of exotic states of matter.

So far, the exact degree to which the available energy levels of graphene need to be filled with electrons (i.e., “doped”) in order for individual phases to stabilize has been very difficult to determine using model calculations. Identifying or designing techniques that can be used to dope graphene to or beyond the van Hove singularity could ultimately lead to interesting observations related to exotic phases of matter, which could in turn pave the way towards the development of new graphene-based technology.
