A tiny antenna could be good for your health—all you have to do is stick it in your brain

Antennas have come a long way from the rabbit ears on your old TV. But the antenna that Northeastern doctoral student Hwaider Lin has been working on since 2015 is about 100 times smaller than the one currently in your smartphone.

New tool simultaneously senses magnetic fields in various directions

Imagine trying to make sense of the cacophony of a speaker playing four songs at once, and you have some idea of the challenge faced by Jenny Schloss and Matt Turner.

'Fudge factors' in physics?

Science is poised to take a "quantum leap" as more mysteries of how atoms behave and interact with each other are unlocked.

Steering material scientists to better memory devices

Ideally, next-generation AI technologies should understand all our requests and commands, extracting them from a huge background of irrelevant information, in order to rapidly provide relevant answers and solutions to our everyday needs. Making these "smart" AI technologies pervasive—in our smartphones, our homes, and our cars—will require energy-efficient AI hardware, which we at IBM Research plan to build around novel and highly capable analog memory devices.

Stephen Hawking: Master of the multiverse

The multiverse challenges science as we know it, and Hawking wasn't pleased with it. But our journey to the edges of time has since reshaped our vision of the cosmos, and ourselves.

'Fudge factors' in physics?

What if your theory to model and predict the electronic structure of atoms isn't accounting for dispersion energy? You come up with some 'fudge factors' to make it all work. But getting the right results for the wrong reasons can only take you so far.

New NSLS-II beamline illuminates electronic structures

On July 15, 2018, the Soft Inelastic X-ray Scattering (SIX) beamline at the National Synchrotron Light Source II (NSLS-II)—a U.S. Department of Energy (DOE) Office of Science User Facility at DOE's Brookhaven National Laboratory—welcomed its first visiting researchers. SIX is an experimental station designed to measure the electronic properties of solid materials using ultrabright x-rays. The materials can be as small as a few microns—one millionth of a meter.

Improved amplifier technology for use in positron emission tomography

In the EU project ENEFRF, researchers at the Ångström Laboratory are working on improving the radio frequency amplifiers that will make technology for cancer diagnostics more efficient, accessible, and affordable. "We are seeing a dramatic increase in the number of PET scans and therefore the costs for society. With upgraded technology, the costs for maintenance and operation will be reduced," says Dragos Dancila, Docent in Applied Physics.

NASA Statement on Soyuz MS-10 Launch Abort

The following is a statement about Thursday’s Soyuz MS-10 launch abort to the International Space Station:

Research on light-matter interaction could improve electronic and optoelectronic devices

New research increases our understanding of how light interacts with atomically thin semiconductors and creates unique excitonic complex particles, multiple electrons, and holes strongly bound together.
