Young people who vape or smoke cigarettes have reduced blood vessel function, breathing efficiency and exercise capacity compared with those who have never smoked or vaped, according to a study published in ERJ Open Research.

Efficiency ratings on portable air conditioners don’t give consumers the full picture, and one type of aircon unit is so inefficient that it should be banned, says Michael Le Page

Reducing motor speed helps the new electric CLA go further on a charge, especially during highway driving. O recorte ajuda a contextualizar a pauta dentro de Auto.

While the auto industry wrings its hands over the electric vehicle market, sweating details like aerodynamic efficiency and range anxiety, a new EV startup based in Lisbon, Portugal, is zagging in a different direction. Amble's new electric buggy won't impress anyone with its 0-6

SpaceX's latest residential dish - the Starlink V5 - is now available in "select areas." It's notably smaller and lighter than the V4 dish with improved power efficiency. It'll be available in more places as SpaceX ramps up production to meet global demand. The company notes that

A newly proposed quantum sensing technique could make it much easier to identify one of physics’ newest and most intriguing classes of magnets: altermagnets. These unusual materials, discovered only a few years ago, appear to combine the speed and efficiency of antiferromagnets w

Researchers have discovered how certain photosynthetic bacteria use a sophisticated quantum mechanism to increase their efficiency when capturing sunlight. The study, published today in the journal Nature Chemistry and led by Professor Jenny Clark, reveals that nature has been us

A groundbreaking superconducting X-ray spectrometer has begun operation at BESSY II, giving Europe its first TES-based system and boosting photon detection efficiency by up to 1,000 times. The advance enables scientists to explore atomically thin materials, nanostructures, and ul

Although the efficiency of organic solar cells has now risen to more than 20%, there are physical limits that make it difficult to further increase their performance. A research team from Linköping University in Sweden, the University of Potsdam, the Paul-Drude-Institut in Berlin

Climate warming is intensifying terrestrial water scarcity and drought risks worldwide. Meanwhile, rising atmospheric CO2 reduces plant stomatal conductance—the openness of leaf pores that governs both CO2 intake and water loss—and improves water-use efficiency, which has been wi

Solar cells and photocatalysts can be surprisingly inefficient. Despite light consisting of many wavelengths, the range that even highly efficient devices use is limited. Other wavelengths, especially long wavelengths, simply pass through the material without being used as energy

The shape of biological structures, ranging from flower petals to the limbs or organs of animals, is often naturally best suited for performing specific functions. Biological structures also often present curved surfaces with specific functional advantages, such as facilitating t
