Earbuds may soon do much more than play music or take phone calls. According to a new international study, the same devices millions of people...

Imagine sitting at your desk during a normal workday. You log into your computer, unaware that a built-in sensing system could be tracking your...

Sodium-ion batteries are emerging as a promising alternative to today’s lithium-ion batteries. While lithium-ion technology powers everything from smartphones to electric cars, lithium is relatively...

Hydrogen is often described as a fuel of the future because when it is used, it produces only water instead of harmful emissions. But making...

Making energetic materials—such as explosives, propellants, and fireworks—is a bit like baking a very sensitive cake. The ingredients must be carefully measured, the mixing must...

Cement is one of the most widely used building materials in the world, but it comes at a high environmental cost. Portland cement alone is...

At the start of the 20th century, electric cars were more common on American roads than gasoline vehicles. In 1900, many drivers relied on lead-acid...

Imagine if a self-driving car could spot a pedestrian before they step into view from behind a building. Engineers at the University of Pennsylvania have...

Talking about flatulence may feel awkward, but scientists say it could reveal important clues about gut health. Researchers at the University of Maryland have developed...

Scientists have developed a new way to produce clean hydrogen using sunlight and liquid metal, offering a promising path toward greener energy made directly...

Modern satellites rely on electromagnetic waveguides—hollow structures that carry high-power signals between components such as antennas and transmitters. Today, these waveguides are usually made from...

Researchers have created a microphone so thin it looks like a human hair, yet tough enough to survive temperatures as high as 1,000°C. Made entirely...

A new supercapacitor based on manganese oxide could combine the storage capacity of batteries with the high power and fast charging of other supercapacitors,...

Helicopters draw a lot of attention with their almost magical ability to hover, fly in any direction and operate without runways. They also help save...

Solar power is about to get a big upgrade, thanks to scientists working on a new kind of solar cell that could change everything. These...

Scientists from the University of New South Wales (UNSW) have developed a groundbreaking rechargeable battery that uses protons—hydrogen ions—rather than lithium. This innovative design could...

Lasers are a lot more than just fancy light shows or tools for scanning your groceries. They play a crucial role in fields like telecommunications,...
