About 70% of the energy we use in everyday life is wasted in the form of heat, produced by engines, factories, and electrical devices. However, researchers from EPFL's School of Engineering have made a significant theoretical ...

Going to the bathroom may not rank among the most pleasant activities of a day, but given some context, we should be quite appreciative.

Autonomous vehicle software used to detect pedestrians is unable to correctly identify dark-skinned individuals as often as those who are light-skinned, according to researchers at King's College in London and Peking University ...

A tailsitter is a fixed-wing aircraft that takes off and lands vertically (it sits on its tail on the landing pad), and then tilts horizontally for forward flight. Faster and more efficient than quadcopter drones, these versatile ...

Most adult humans are innately able to pick up objects in their environment and hold them in ways that facilitate their use. For instance, when picking up a cooking utensil, they would normally grab it from the side that ...

If coal and natural gas power generation were 2% more efficient, then every year, there could be 460 million fewer tons of carbon dioxide released and 2 trillion fewer gallons of water used. A recent innovation to the steam ...

Deep neural networks are generating much of the exciting progress stemming from generative AI. But their architecture relies on a configuration that is a virtual speedbump, ensuring the maximal efficiency can not be obtained.

Cellular solids are materials composed of many cells that have been packed together, such as in a honeycomb. The shape of those cells largely determines the material's mechanical properties, including its stiffness or strength. ...

Engineers in Australia have found a way of making stronger concrete with roasted used-coffee grounds, to give the drink-additive a "double shot" at life and reduce waste going to landfills.

Advanced smartphone features attract users who want more from their devices, especially in health and entertainment areas, but do these features create a security risk when making or receiving actual calls? A team of academic ...

Efficient and cheap batteries that can also capture harmful emissions could be right around the corner, thanks to a new system that speeds up the development of catalysts for lithium-CO2 (Li-CO2) batteries.

Ternary organic solar cells, in which the photoactive layer is made of three different organic materials, have been found to achieve highly promising power conversion efficiencies (PCEs). While these ternary organic solar ...
