What if the thermal noise that hinders the efficiency of both classical and quantum computers could, instead, be used as a power source? What if computers could make use of the noise instead of suppressing or overcoming it? ...

The human body continuously generates a rich spectrum of vibrations—often without us ever noticing. Everyday unconscious activities such as breathing, speaking, and swallowing all produce subtle yet distinct mechanical ...

Researchers have developed photonic computing chips that overcome key limitations for a type of neural network known as a photonic spiking neural system. By enabling fast learning and decision making using purely light-based ...

Rechargeable batteries are everywhere—from portable electronic devices and electric vehicles to renewable energy storage. Battery failures are often due to the loss or chemical degradation of the electrolyte.

Purdue University engineers have developed a patent-pending method to decrease hazardous strikes to underground utility pipes during construction projects. This could lower related financial losses, service disruptions, injuries ...

The internet is rife with anonymous accounts as users adopt pseudonyms, sometimes for genuine reasons like speaking freely, and other times for nefarious ones. But this era of online privacy could be coming to a close. In ...

Data centers—the warehouse-sized buildings that store photos, stream movies and train artificial intelligence—are voracious consumers of electricity. A surprisingly large share of that power never reaches a microchip. ...

Spurred by EVs and electrified aviation, global demand for lithium-ion batteries is expected to more than double its 2023 levels by 2030, far outstripping demand, according to S&P Global Insights. New batteries must be powerful, ...

Many engineering challenges come down to the same headache—too many knobs to turn and too few chances to test them. Whether tuning a power grid or designing a safer vehicle, each evaluation can be costly, and there may ...

Birds have an ability to fly through obstacles by shifting their shape in flight, which is difficult to reproduce in uncrewed aerial vehicles, commonly known as UAVs or drones. A new study from researchers at the University ...

Apple CEO Tim Cook promised a "big week" of product announcements has seen the introduction of a new budget-friendly iPhone trim, an entry-level MacBook tier, updated iPad Air models, refreshed monitors and higher-end chipsets. ...

Every day, algorithms make consequential decisions about millions of people's lives—who gets approved for a mortgage, who is called back for a job interview, who receives priority care in a hospital emergency room. Most ...
