Mechanoluminescent (ML) materials are attractive for haptic interface sensors for next-generation technologies, including bite-controlled user interface, health care motion monitoring, and piconewton sensing, because they emit light under mechanical stimulation without an external power source. However, their intrinsically broad emission spectra can degrade resolution and introduce noise in sensing applications, necessitating further technological development.

Every year, billions of dollars' worth of crops worldwide perish due to pre-harvest sprouting (PHS), a phenomenon in which grain or seeds germinate on the plant before harvest. The process is triggered by a variety of factors, such as warm, moist weather, which can spoil the crop and threaten the global food supply. But this could be a thing of the past, as a team of researchers, primarily from the Carlsberg Research Laboratory in Denmark, has uncovered the genetic mechanism that controls when barley should sprout.

A new study led by researchers from Oxford University, Southwest Research Institute and the Planetary Science Institute in Tucson, Arizona has provided the first evidence of significant heat flow at Enceladus's north pole, overturning previous assumptions that heat loss was confined to its active south pole.

An international study involving INRAE and coordinated by China Agriculture University has shown that the practice of crop rotation outperforms continuous monoculture in terms of yield, nutritional quality and farm revenues. The results, based on more than 3600 field observations from 738 experimental trials across six continents, have now been published in Nature Communications.

A new delivery particle developed at MIT could make mRNA vaccines more effective and potentially lower the cost per vaccine dose.

James D. Watson, whose co-discovery of the twisted-ladder structure of DNA in 1953 helped light the long fuse on a revolution in medicine, crimefighting, genealogy and ethics, has died. He was 97.

There are easier ways to cross an ocean, but few are as slick or stylish as the remora's whale-surfing joyride.

Placing materials under extremely strong magnetic fields can give rise to unusual and fascinating physical phenomena or behavior. Specifically, studies show that under magnetic fields above 100 tesla (T), spins (i.e., intrinsic magnetic orientations of electrons) and atoms start forming new arrangements, promoting new phases of matter or stretching a crystal lattice.

During a severe drought and heat wave in 2023, Amazonian lakes reached their highest recorded temperatures. Water temperatures in some areas climbed to an astonishing 41 degrees Celsius (105.8 degrees Fahrenheit) and resulted in the deaths of thousands of aquatic animals, including dozens of river dolphins.

This week, researchers reported finding a spider megacity in a sulfur cave on the Albania-Greece border, and experts say that you, personally, have to go live there. Economists are growing nervous about the collapse of the trillion-dollar AI bubble. And a new study links physical activity levels with the risk of digestive system cancers.
