TAMPA, Fla. — Verizon is launching satellite-enabled emergency text and location services this fall for compatible Android smartphones in the United States at no extra cost for customers.
The telecoms giant announced a partnership Aug. 28 to deliver the service with Skylo, which has developed ground infrastructure enabling L-band geostationary satellites to reach devices using the latest standards-based chipsets.
Google’s family of Pixel Pro devices and the Samsung Galaxy S25 are set to be among the first to get access to Skylo’s partner satellites, enabling emergency narrowband connectivity when cell towers are out of reach.
A team of electrical and computer engineers at Shanghai Institute of Microsystem and Information Technology, Chinese Academy of Sciences, working with one colleague from City University of Hong Kong and another with Fudan University, has developed a new two-dimensional, low-power-consumption field-effect transistor (FET) that could allow smartphones to need recharging less often.
In their paper published in the journal Nature, the group describes how they overcame problems with high gate leakage and low dielectric strength that have stymied other researchers looking to create smaller and thinner computer chips. Two of the team members (Ziao Tian and Zengfeng Di) have published a Research Briefing, summarizing their work in the same journal issue.
Over the past several years, computer engineers have been searching for new materials that will allow further miniaturization of silicon field-effect transistors. This will enable the addition of more features in phones and other devices without making them bigger. It is also a necessity for the development of 5G devices that will come with AI applications that are still in development.
For the past decade, disordered rock salt has been studied as a potential breakthrough cathode material for use in lithium-ion batteries and a key to creating low-cost, high-energy storage for everything from cell phones to electric vehicles to renewable energy storage.
A new MIT study is making sure the material fulfills that promise.
Led by Ju Li, the Tokyo Electric Power Company Professor in Nuclear Engineering and professor of materials science and engineering, a team of researchers describe a new class of partially disordered rock salt cathode, integrated with polyanions—dubbed disordered rock salt-polyanionic spinel, or DRXPS—that delivers high energy density at high voltages with significantly improved cycling stability.
Everybody is talking about Artificial Intelligence (AI). It is in our computers, services and even our mobile phones. The AI composes our messages, predicts our moves and even takes photos for us. Are we – humans – going to become “obsolete” in a matter of years?! Maybe there is a last chance – Intelligence Amplification (IA).
While an AI needs to be developed from scratch, we humans, already have great intelligence thanks to countless years of evolution. A modern human’s brain is an awesome tool!
Among us, there are some geniuses, but imagine if everybody can become one. And not just a genius, but a super-genius. Smarter than every person who has ever lived before! This is the idea behind Intelligence Amplification. To use our intelligence as a base and to add computers to make us smarter beyond our imagination. A hybrid, a work of art!
Apple is continuing to expand manufacturing in India, and the country will reportedly produce the iPhone 16 Pro and iPhone 16 Pro Max as well as the regular models.
Originally, India only manufactured older iPhones, and then chiefly because it avoided import tax. More recently in its expansion of production in the country, India has taken on manufacturing current models of the iPhone 15.
According to Bloomberg, Apple intends to expand still further. For the first time, India will manufacture the iPhone 16 Pro and iPhone 16 Pro Max.
From the high-voltage wires that carry electricity over long distances, to the tungsten filaments in our incandescent lights, we may have become accustomed to thinking that electrical conductors are always made of metal. But for decades, scientists have been working on advanced materials based on carbon-based oligomer chains that can also conduct electricity. These include the organic light-emitting devices found in some modern smartphones and computers.
In quantum mechanics, electrons are not just point particles with definite positions, but rather can become ‘delocalized’ over a region. A molecule with a long stretch of alternating single-and double-bonds is said to have pi-conjugation, and conductive polymers operate by allowing delocalized electrons to hop between pi-conjugated regions – somewhat like a frog hopping between nearby puddles. However, the efficiency of this process is limited by differences in the energy levels of adjacent regions.
Fabricating oligomers and polymers with more uniform energy levels can lead to higher electrical conductivity, which is necessary for the development of new practical organic electronics, or even single-molecule wires.
Peel apart a smartphone, fitness tracker or virtual reality headset, and inside you’ll find a tiny motion sensor tracking its position and movement. Bigger, more expensive versions of the same technology, about the size of a grapefruit and a thousand times more accurate, help navigate ships, airplanes and other vehicles with GPS assistance.
Now, scientists are attempting to make a motion sensor so precise it could minimize the nation’s reliance on global positioning satellites. Until recently, such a sensor — a thousand times more sensitive than today’s navigation-grade devices — would have filled a moving truck. But advancements are dramatically shrinking the size and cost of this technology.
For the first time, researchers from Sandia National Laboratories have used silicon photonic microchip components to perform a quantum sensing technique called atom interferometry, an ultra-precise way of measuring acceleration. It is the latest milestone toward developing a kind of quantum compass for navigation when GPS signals are unavailable.
An automated computational approach to the optical lens design of imaging systems promises to provide optimal solutions without human intervention, slashing the time and cost usually required. The result could be improved cameras for mobile phones with superior quality or new functionality.
