Quantum tunneling pushes the limits of self-powered sensors

Using quantum tunneling, scientists have developed self-powered sensors that can run for more than a year. Shantanu Chakrabartty's laboratory has been working to create sensors...

Magnetars could be behind some fast radio bursts, shows study

Magnetars—a type of neutron star believed to have an extremely powerful magnetic field—could be the source of some fast radio bursts, new research suggests. Though...

Scientists synthesize ‘bright’ quantum bits

With their ability to harness the strange powers of quantum mechanics, qubits are the basis for potentially world-changing technologies—like powerful new types of computers...

Scientists turn IBM computer into a quantum material

In a groundbreaking study, a group of University of Chicago scientists announced they were able to turn IBM’s largest quantum computer into a quantum...

Galaxies have gotten hotter as they’ve gotten older

Who says you can't get hotter with age? Researchers from Johns Hopkins University and other institutions have found that, on average, the temperature of galaxy...

Astronomers detect ultrabright radio flashes in our own galaxy for the first time

Fast radio bursts are extremely bright flashes of energy that last for a fraction of a second, during which they can blast out more...

Scientists find new way to see dark matter

A small team of astronomers have found a new way to 'see' the elusive dark matter haloes that surround galaxies, with a new technique...

Scientists reveal some mystery of fast radio bursts from the universe

In the vast universe, some extremely strong radio waves occasionally blink, with duration of only milliseconds. Such fast radio bursts were discovered by astronomers in...

Scientists unlock mysterious cause of fast radio bursts from our Galaxy

A suite of radio antennas, including those making up Caltech's STARE2 (Survey for Transient Astronomical Radio Emission 2) project, together with other ground- and...

How some massive stars become isolated in the universe

A pair of University of Michigan studies reveals how some massive stars--stars eight or more times the mass of our sun--become isolated in the...
