'Neutronic molecules': Study shows neutrons can bind to quantum dots

Neutrons are subatomic particles that have no electric charge, unlike protons and electrons. That means that while the electromagnetic force is responsible for most of the interactions between radiation and materials, neutrons ...

'Frankenstein design' enables 3D printed neutron collimator

The time-tested strategy of "divide and conquer" took on a new, high-tech meaning during neutron experiments by scientists at the Department of Energy's Oak Ridge National Laboratory. They discovered that the problems they ...

Exploding stars are rare but emit torrents of radiation—one close enough to Earth could threaten life on the planet

Stars like the sun are remarkably constant. They vary in brightness by only 0.1% over years and decades, thanks to the fusion of hydrogen into helium that powers them. This process will keep the sun shining steadily for about ...

A cosmic 'speed camera' just revealed the staggering speed of neutron star jets in a world first

How fast can a neutron star drive powerful jets into space? The answer, it turns out, is about one-third the speed of light, as our team has just revealed in a new study published in Nature.

Gravitational waves may have made human life possible

Could it be that human existence depends on gravitational waves? Some key elements in our biological makeup may come from astrophysical events that occur because gravitational waves exist, a research team headed by John R. ...

Plasma fusion: Adding just enough fuel to the fire

How much fuel can we add to the fire while still maintaining control? Metaphorically speaking, that's the question one team at the U.S. Department of Energy's Princeton Plasma Physics Laboratory (PPPL) has been asking themselves ...

Team discovers fundamentally new way to detect radiation involving cheap ceramics

The radiation detectors used today for applications like inspecting cargo ships for smuggled nuclear materials are expensive and cannot operate in harsh environments, among other disadvantages. Now, MIT engineers have demonstrated ...

Anthropocene or not, it is our current epoch that we should be fighting for

Has the Holocene epoch of the past 11,700 years been supplanted by the proposed Anthropocene epoch of today? Although it's broadly accepted that planetary systems have changed as a result of human influence, a panel of experts ...

Testing begins on sensitive neutrino detector for nonproliferation and fundamental physics

Neutrinos and antineutrinos are nearly massless particles produced in many nuclear reactions, including the fission of uranium in nuclear power plants on Earth and the fusion reactions at the core of the sun.
