First astrophysical detection of the helium hydride ion

23-Apr-2019

HeH+ was the first molecule that formed when, almost 14 billion years ago, falling temperatures in the young Universe allowed recombination of the light elements produced in the Big Bang. At that time, ionized hydrogen and neutral helium atoms reacted to form HeH+. Despite its importance in the ...

Evidence for a new property of quantum matter revealed

13-Jun-2018

A theorized but never-before detected property of quantum matter has now been spotted in the lab, a team of scientists reports. The team proved that a particular quantum material can demonstrate electrical dipole fluctuations - irregular oscillations of tiny charged poles on the material - even ...

Unexpected effect could lead to lower-power memory, computing devices

20-Mar-2018

An unexpected phenomenon known as zero field switching (ZFS) could lead to smaller, lower-power memory and computing devices than presently possible. The image shows a layering of platinum (Pt), tungsten (W), and a cobalt-iron-boron magnet (CoFeB) sandwiched at the ends by gold (Au) electrodes on ...

Diamonds may not be so rare as once thought

Research won't mean deep discounts at local jewelry stores.

05-Nov-2015

Diamonds may not be as rare as once believed, but this finding in a new Johns Hopkins University research report won't mean deep discounts at local jewelry stores. "Diamond formation in the deep Earth, the very deep Earth, may be a more common process than we thought," said Johns Hopkins ...

Glass paint could keep metal roofs and other structures cool even on sunny days

18-Aug-2015

Sunlight can be brutal. It wears down even the strongest structures, including rooftops and naval ships, and it heats up metal slides and bleachers until they're too hot to use. To fend off damage and heat from the sun's harsh rays, scientists have developed a new, environmentally friendly paint ...

Wind energy: On the grid, off the checkerboard

03-Apr-2014

As wind farms grow in importance across the globe as sources of clean, renewable energy, one key consideration in their construction is their physical design -- spacing and orienting individual turbines to maximize their efficiency and minimize any "wake effects," where the swooping blades of one ...

It's all coming back to me now

Researchers find caffeine enhances memory

14-Jan-2014

For some, it's the tradition of steeping tealeaves to brew the perfect cup of tea. For others, it's the morning shuffle to a coffee maker for a hot jolt of java. Then there are those who like their wake up with the kind of snap and a fizz usually found in a carbonated beverage. Regardless of the ...
