A new device harvests two types of energy during the daytime, making it cool on one end and hot on the other, to generate electricity around the clock. With further improvements, the device could be used in off-grid Internet-of-things sensors. The details were published in the journal Science and Technology of Advanced Materials. Scientists have […]
The updated iPad Air that Apple is expected to unveil at tomorrow’s “Peek Performance” event could include the same M1 chip that’s featured in the 2021 iPad Pro, according to information shared by 9to5Mac. Last year’s iPad Pro was the first iPad to get Apple’s M-series chip, and adding the M1 to the iPad Air […]
Web browsers are famously complicated pieces of software with plenty of very demanding features. In turn, browser developers take performance very seriously, which has led to one of the most competitive (friendly) rivalries in all of tech. Thanks to a number of optimizations to Chrome’s code, and even the way code is compiled, it has […]
Researchers have made tiny ‘skyscrapers’ for communities of bacteria, helping them to generate electricity from just sunlight and water. The researchers, from the University of Cambridge, used 3D printing to create grids of high-rise ‘nano-housing’ where sun-loving bacteria can grow quickly. The researchers were then able to extract the bacteria’s waste electrons, left over from […]
Solid-state batteries, currently used in small electronic devices like smart watches, have the potential to be safer and more powerful than lithium-ion batteries for things such as electric cars and storing energy from solar panels for later use. However, several technical challenges remain before solid-state batteries can become widespread. A Sandia National Laboratories-led study, published […]
Microsoft will be celebrating the one-year birthday of Windows 11 with the release of a major update codenamed “Sun Valley 2”. If you have a Windows 11 device, you’ll get the update automatically, and for absolutely free provided that your device is already on the new OS. As we draw ever closer to the release […]
What just happened? Lapsus$, a hacking group that leaked confidential information from Nvidia just last week, has reportedly moved to a new target: Samsung. The hackers have claimed an attack that leaked 190GB of confidential information from the South Korean technology giant, including encryption data and source code for Samsung’s most recent devices. The hackers behind […]
Texas A&M AgriLife Research scientists are using artificial intelligence to set a new world record for producing algae as a reliable, economic source for biofuel that can be used as an alternative fuel source for jet aircraft and other transportation needs. Joshua Yuan, Ph.D., AgriLife Research scientist, professor and chair of Synthetic Biology and Renewable […]
The most important properties of a semiconductor to be used as a solar cell include the mobility and lifetime of electrons and “holes”. Both quantities can be measured without contacts with spectroscopic methods using terahertz or microwave radiation. However, measurement data found in literature often differ by orders of magnitude. This has made it difficult […]
There are clear environmental benefits to driving an electric vehicle (EV). But will it leave you stranded between charging stations? Here we’ll look at how an EV’s battery range compares to a tank of gasoline. How Far Can You Drive an EV on a Single Charge? “Range anxiety,” or the fear that an EV won’t […]
BARCELONA — Mobile World Congress made a big comeback this year — but the term on everyone’s lips wasn’t “smartphones” or “5G.” Instead, it was the “metaverse,” a vague concept used to describe vast digital worlds in which users can work, play games or even party. The term has been the talk of the tech […]
It’s time to make the switch to triple-pane windows. That’s the message from a series of studies led by the Department of Energy’s Pacific Northwest National Laboratory in collaboration with a coalition of public and private partners. “Lower costs, greater availability, and the drive to reduce carbon emissions are pushing us toward a tipping point […]
