Wondering if meal kits are worth it? Here's why meal delivery services are worth the investment in 2024.

Mathematicians from RUDN University have proposed a system that helps to use energy more efficiently. It is based on the Internet of Things and the digital twin of the household. The neural network optimally distributes tasks and decides how to divide energy between devices. The study is published in Sensors.

A space solar-powered satellite (SSPS) is a tremendous energy system that collects and converts solar power to electric power in space, and then transmits the electric power to Earth, spacecraft, or moving targets via microwave. It is regarded as one of the most potential ways to solve the problem of energy crisis.

The University of Malaga (UMA) has participated in an international study with the Future Power Systems Group of the University of Birmingham (UK) that investigates how to reduce pollutant emissions from vehicles without affecting engine performance.

As power grids evolve to incorporate new variable renewable energy sources and adapt to growing peak electricity demands, balancing the grid—scheduling appropriate electricity supply to match demand—will become increasingly challenging.

Our energy systems are characterized by two important injustices. First of all, not all people have the same degree of access to these systems (and their advantages). Secondly, the negative consequences of the systems—particularly climate change—are distributed unfairly. TU/e researcher Natascha van Bommel investigated how the current energy transitions can be used to mitigate these injustices.

A black sedan cruises silently down a quiet suburban road, driver humming Christmas carols quietly while the car's autopilot handles the driving. Suddenly, red flashing lights and audible warnings blare to life, snapping the driver from their peaceful reprieve. They look at the dashboard screen and see the outline of a car speeding toward them for a head-on collision, yet the headlights reveal nothing ahead through the windshield.

Research in recent years displays that several chemical modifications (binders, composite materials, and electrolytes) provide superior stability and enhance electrochemical performance in Si-based anodes in lithium-ion batteries (LIBs). Thus far, several different chemical interactions on structural alterations to Si-based anode materials have been tried to enhance Li+ kinetics, structural stability, and volume development control throughout the delithiation/lithiation process.

Electric vehicles that typically weigh more than gasoline-powered cars can easily crash through steel highway guardrails that are not designed to withstand the extra force, raising concerns about the nation's roadside safety system, according to crash test data released Wednesday by the University of Nebraska.

Harmful emissions from the industrial sector could be reduced by up to 85% across the world, according to new research. The sector, which includes iron and steel, chemicals, cement, and food and drink, emits around a quarter of global greenhouse gas (GHG) emissions—planet-warming gases that result in climate change and extreme weather.

When President Nayib Bukele announced plans to create the world's first "Bitcoin City," a futuristic metropolis financed by cryptocurrency bonds, American Corbin Keegan packed up his life in Chicago and headed for El Salvador.

After hours of routine operations, an air traffic controller gets a radio call from a small aircraft whose cockpit indicators can't confirm that the plane's landing gear is extended for landing. The controller arranges for the pilot to fly low by the tower so the controller can visually check the plane's landing gear. All appears well. "It looks like your gear is down," the controller tells the pilot.

Look up "lifelong learning" online, and you'll find a laundry list of apps to teach you how to quilt, play chess or even speak a new language. Within the emerging fields of artificial intelligence (AI) and autonomous devices, however, "lifelong learning" means something different—and it is a bit more complex. It refers to the ability of a device to continuously operate, interact with and learn from its environment—on its own and in real time.

Some recent mergers, acquisitions and investments in the business world have highlighted the strategic value of data to companies. These businesses are not just buying assets or market share—they are also acquiring or investing in large, complementary datasets. This process is known in the business world as horizontal integration.

A researcher from the New Jersey Institute of Technology has published a perspective paper that examines sentience and its application to artificial intelligence (AI) and robotics. Sentience describes the ability to sense and feel, drawing its meaning from the Latin word sentire which means "to feel." The paper addresses a set of ideological commitments at stake in debates over sentient machines. The author proposes that artificial sentience is both necessary and impossible.

Lithium-ion batteries have been pivotal in powering modern technology, from mobile devices to electric vehicles. As demand for higher performance batteries grows, the focus has shifted from merely optimizing battery materials to rethinking the entire cell design and architecture.

A new system that brings together real-world sensing and virtual reality would make it easier for building maintenance personnel to identify and fix issues in commercial buildings that are in operation. The system was developed by computer scientists at the University of California San Diego and Carnegie Mellon University.

It's called TinyLlama and it's taken the research world by storm because of how much power it packs.
