“That raises the theoretical efficiency of the cell to 80 percent, which is quite remarkable.” Scientists have created a heat-resistant thermal emitter that could significantly improve the efficiency of solar cells. The novel component is designed to convert heat from the sun into infrared light, which can than be absorbed by solar cells to make

A new polymer-based solar-thermal device is the first to generate power from both heat and visible sunlight — an advance that could shave the cost of heating a home by as much as 40 percent. Geothermal add-ons for heat pumps on the market today collect heat from the air or the ground. This new device

Potential to revolutionize point-of-care medicine You wouldn’t know it from appearances, but a metal cube the size of a toaster, created at the University of Alberta, is capable of performing the same genetic tests as most fully equipped modern laboratories—and in a fraction of the time. At its core is a small plastic chip developed

A team of researchers has built a mathematical model that describes the molecular events associated with the beginning stage of learning and memory formation in the human brain. The research, published in the journal Proceedings of the National Academy of Sciences, paves the way for understanding cognitive function and neurodegenerative diseases—at the molecular and cellular

At least 115 people die every day in the U.S. after overdosing on opioids, according to the National Institute on Drug Abuse. And in 2016, illegal injectable opioids became the most common drug involved in overdose-related deaths. This spike has led to a national public health crisis and epidemic. During an overdose, a person breathes slower or stops

UCLA engineers have made major improvements on their design of an optical neural network –a device inspired by how the human brain works – that can identify objects or process information at the speed of light. The development could lead to intelligent camera systems that figure out what they are seeing simply by the patterns of

Its Braille interface is easy to use and able to display over 100 characters The Clarity mobile phone concept by designer Mark DiLella has a host of features that aim to help the visually impaired make full use of the device. Its Braille interface is easy to use and able to display over 100 characters.

Now here’s a clever solution for transporting, storing and charging multiple tablet computers. The PowerCRATE is a portable (you can even air-freight tablets in situ) solution for charging 25 tablets simultaneously without connecting any power leads. Any brand of tablet can be used (including iPad, Samsung Galaxy and Microsoft Surface), charging can be on demand

An inventor’s new gizmo could signal the end of the road for searching for a parking space.   Adrian Bone from Lewes has produced a ‘parking patch’, a sensor to be placed in parking spaces to detect when they are being used. The 52-year-old said the invention would “revolutionise the parking industry and could mean
