An electrooxidation process efficiently converts glycerol, a byproduct of biodiesel production, into high-value three-carbon compounds.

A sweat-powered wearable has the potential to make continuous, personalized health monitoring as effortless as wearing a Band-Aid. Engineers have developed an electronic finger wrap that monitors vital chemical levels — such as glucose, vitamins, and even drugs — present in the same fingertip sweat from which it derives its energy.

In creating a pair of new robots, researchers cultivated an unlikely component, one found on the forest floor: fungal mycelia. By harnessing mycelia’s innate electrical signals, the researchers discovered a new way of controlling ‘biohybrid’ robots that can potentially react to their environment better than their purely synthetic counterparts.

A model developed by evolutionary mathematicians shows that as conditions for cooperation improve between two species, mutually beneficial behavior can unexpectedly become unbalanced. Cooperative behavior pools in one species, the other consumes the spoils.

New research shows consumers use ‘happier’ words to search for products when they are in a good mood. Researchers have connected those positive search terms with an increased likelihood of clicking on search engine ads.

It’s 7 billion years ago, and the universe’s heyday of star formation is beginning to slow. What might our Milky Way galaxy have looked like at that time? Astronomers have found clues in the form of a cosmic question mark, the result of a rare alignment across light-years of space.

Some per- and polyfluoroalkyl substances (PFAS) are poorly degradable and are also known as ‘forever chemicals’. They adversely affect health and can lead to liver damage, obesity, hormonal disorders, and cancer. A research team has investigated the effects of PFAS on the brain. Using a combination of modern molecular biology methods and the zebrafish model,

Rain and water in ponds and lakes slowly seeps into the soil, moving through minute cracks to refill underground aquifers. Per- and polyfluoroalkyl substances (PFAS), often described as forever chemicals, can tag along into groundwater that’s later removed for drinking. Researchers analyzed water from over 100 wells in Denmark for one particularly persistent PFAS: trifluoroacetate.

A new study shines a light on the enormous scale of uncollected rubbish and open burning of plastic waste in the first ever global plastics pollution inventory. Researchers used A.I. to model waste management in more than 50,000 municipalities around the world. This model allowed the team to predict how much waste was generated globally

Nuclear clocks would measure time based on changes inside an atom’s nucleus, which would make them less sensitive to external disturbances and potentially more accurate than atomic clocks. These clocks could lead to improved timekeeping and navigation, faster internet speeds, and advances in fundamental physics research. Scientists have demonstrated key components of a nuclear clock,
