Chinese government rolls out coronavirus ‘close contact detector’ app

February 18th, 2020 at 12:30 pm » Comments Off

China has rolled out an app that lets people check whether they have been in close contact with someone infected by the coronavirus. The “close contact detector,” as BBC puts it, notifies users if they have had exchanges with any individuals who have been confirmed or suspected of carrying the virus. All users need to […]



Graphene amplifier unlocks hidden frequencies in the electromagnetic spectrum

February 18th, 2020 at 12:26 pm » Comments Off

Light in the THz frequencies hits the ‘sandwich’ and is reflected with additional energy. Credit: Loughborough University Researchers have created a unique device which will unlock the elusive terahertz wavelengths and make revolutionary new technologies possible. Terahertz waves (THz) sit between microwaves and infrared in the light frequency spectrum, but due to their low energy, […]



Lasers etch a ‘perfect’ solar energy absorber

The secret to winning the war for talent

February 17th, 2020 at 12:22 pm » Comments Off

In the long siege known as the war for talent, employers need a new battle plan. Instead of trying desperately to recruit from the outside to fill a growing skills gap, companies should turn to the resources that exist within their own workforces. This is a build versus buy strategy, with greater emphasis placed on […]



8 powerful examples of AI for good

February 17th, 2020 at 12:19 pm » Comments Off

Amid the cacophony of concern over artificial intelligence (AI) taking over jobs (and the world) and cheers for what it can do to increase productivity and profits, the potential for AI to do good can be overlooked. Technology leaders such as Microsoft, IBM, Huawei and Google have entire sections of their business focused on the […]



New theory of complex emotions

We updated Roger Hargreaves’s Little Miss and Mr. Men universe as a suggestion to include some of our new emotions. Illustration: Zohar Lazar  If You Can Say It, You Can Feel It Some scientists believe we have infinite emotions, so long as we can name them. Sometime last year, I came across the word hangxiety, […]



New research explains how solar panels could soon be generating power at night

February 16th, 2020 at 12:44 pm » Comments Off

As beneficial as current solar panel technology has been in our quest to switch to renewable energy, such panels can’t generate electricity at night. Now, new research suggests it could be possible to design panels that can operate around the clock. Under optimum conditions, at night these specially designed photovoltaic cells could generate a quarter […]



The sun is still a burning mystery. That may be about to change.

February 16th, 2020 at 12:38 pm » Comments Off

The historic launch of the new European Solar Orbiter helps foster a golden age for understanding our nearest star. On Sunday evening, a rocket lit up Florida’s nighttime sky as it ferried a spacecraft toward a first-of-its-kind adventure to the sun. Even though our home star smolders every day in our skies, humans have only […]



Scientists create ‘chemical gardens’ that can be used as bone substitute materials

February 16th, 2020 at 12:34 pm » Comments Off

A new way of making bone-replacement materials that allows for cells to grow around and inside them has been developed by researchers at the University of Birmingham. The team adopted a novel approach called chemobrionics, in which chemical components are controllably driven to react together in specific ways, enabling the self-assembly of intricate bio-inspired structures. […]



A game plan for quantum computing

February 15th, 2020 at 12:37 pm » Comments Off

Pharmaceutical companies have an abiding interest in enzymes. These proteins catalyze all kinds of biochemical interactions, often by targeting a single type of molecule with great precision. Harnessing the power of enzymes may help alleviate the major diseases of our time. Unfortunately, we don’t know the exact molecular structure of most enzymes. In principle, chemists […]
