Cheaper, changing and crucial: the rise of solar power

Generating power from sunlight bouncing off the ground, working at night, even helping to grow strawberries: solar panel technology is evolving fast as costs plummet for a key segment of the world's energy transition.

Boeing delivers first 787 in a year

Boeing delivered a 787 Dreamliner to American Airlines on Wednesday, the first of that aircraft to be sent to a customer in over a year due to defects discovered in the plane.

Disney+ ad-free subscription cost to rise by 38% in December

Walt Disney Co. said Wednesday it is raising prices for streaming subscribers in the U.S. who want to watch Disney+ without ads, as more viewers switch to what CEO Bob Chapek described as the "best value in streaming."

Prediction of human movement during disasters could allow for more effective emergency response

The COVID-19 pandemic, bigger and more frequent wildfires, devastating floods, and powerful storms have become unfortunate facts of life. With each disaster, people depend on the emergency response of governments, nonprofit organizations, and the private sector for aid when their lives are upended. However, a complicating factor in delivering that aid is that people tend to d

Finding order using chaos: Synchronization of spiking oscillators helps build physical reservoirs

Engineers at the Tokyo Institute of Technology (Tokyo Tech) have demonstrated a computational approach using a ring network of coupled spiking oscillators with chaotic dynamics implemented on analog hardware. This new approach is based on the emergence and pattern formation phenomena that occur under "incomplete synchronization" within chaotic dynamics. In the future, it co

Robot arms are replacing shelf stockers in Japan's stores

Telexistence Inc. and FamilyMart Co. are rolling out a fleet of AI-driven robots to restock shelves in 300 convenience stores across Japan.

Researchers discover innovative approach to make novel lithium-ion battery materials

Researchers at Boise State University have developed a new approach to making novel lithium-ion battery materials. Starting from an amorphous (i.e., a material lacking long-range order) niobium oxide, the team discovered that the very act of cycling the material with lithium induces a transformation to a novel crystalline Nb2O5 anode with exceptional Li storage and fast cycling. This pr

Can WhatsApp messages be secure and encrypted—but traceable at same time?

Cryptographers love an enigma, a problem to solve—and this one has it all. Indestructible codes, secret notes, encryption and decryption.

AI may come to the rescue of future firefighters

In firefighting, the worst flames are the ones you don't see coming. Amid the chaos of a burning building, it is difficult to notice the signs of impending flashover—a deadly fire phenomenon wherein nearly all combustible items in a room ignite suddenly. Flashover is one of the leading causes of firefighter deaths, but new research suggests that artificial intelligence (AI) could provide first responders with a much-neede

Local renewable energy employment can fully replace US coal jobs nationwide

Across the United States, local wind and solar jobs can fully replace the coal-plant jobs that will be lost as the nation's power-generation system moves away from fossil fuels in the coming decades, according to a new University of Michigan study.

New programmable materials can sense their own movements

MIT researchers have developed a method for 3D printing materials with tunable mechanical properties, which can sense how they are moving and interacting with the environment. The researchers create these sensing structures using just one material and a single run on a 3D printer.

Effective crew resource management vital to police air support, research shows

Real-world research has shown, for the first time, that the theory of effective crew resource management makes an "invaluable contribution" to the safety and efficiency of police air support in England and Wales.

The Internet of Things needs ultra-compact supercapacitors

Increased demand for super tiny electronic sensors coming from healthcare, environmental services and the Internet of Things is prompting a search for equally tiny ways to power these sensors. A review of the state of ultracompact supercapacitors, or "micro-supercapacitors," concludes there is still a lot of research to be done before these devices can deliver on their promise.

Social media offers parents more controls. But do they help?

As concerns about social media's harmful effects on teens continue to rise, platforms from Snapchat to TikTok to Instagram are bolting on new features they say will make their services safer and more age appropriate. But the changes rarely address the elephant in the the room—the algorithms pushing endless content that can drag anyone, not just teens, into harmful rabbit holes.

Facebook use plunges among US teens: survey

US teens have left Facebook in droves over the past seven years, preferring to spend time at video-sharing venues YouTube and TikTok, according to a Pew Research Center survey data out Wednesday.

Epic Games no longer blocked in Indonesia after registering with government

Epic Games was blocked briefly from the world's fourth-most populated country but on Tuesday complied with Indonesia's requirement that it register with its ministry of information.

A union drive is underway at Amazon's huge new North Carolina facility. Can workers win?

The Amazon distribution center in Garner, North Carolina, is massive. Located a few miles southeast of downtown Raleigh, it covers 2 million square feet and houses multiple departments across four floors. The facility, known as RDU1, employs more than 4,000 people who work shifts spanning all hours of the day and night, seven days a week.

The importance of protecting privacy in a post-Roe world

After the U.S. Supreme Court's controversial decision in June 2022 to overturn Roe v. Wade and eliminate an almost 50-year federal right to abortion, data privacy advocates are sounding the alarm about the potential dangers of authorities weaponing digital data from prospective health care patients.

How artificial intelligence can make our food safer

Food recalls could be a thing of the past if artificial intelligence (AI) is utilized in food production, according to a recent study from UBC and the University of Guelph.

Watch tiny electromechanical robots that are faster than cheetahs for their size

A team of researchers at Johannes Kepler University, in Austria, has developed a series of tiny, steerable electromechanical robots that can walk, run, jump and swim at high speeds for their size. In their paper published in the journal Nature Communications, the group describes how they built their robots and suggests possible uses for them.
