Scientists have discovered a new cause for asthma that sparks hope for treatment that could prevent the life-threatening disease. …read more

Are universities connected to local sustainability? A new study suggests yes…and no.

Are universities connected to local sustainability? A new study suggests yes…and no.

A new study finds that universities scoring strongly on measures of sustainability are associated with innovation and economic growth in their surrounding communities. However, the study did not find similar connections between university sustainability performance and environmental sustainability in their home communities. …read more

Intelligent liquid

Intelligent liquid

Researchers have developed a programmable meta-fluid with tunable springiness, optical properties, viscosity and even the ability to transition between a Newtonian and non-Newtonian fluid. The first-of-its-kind meta-fluid uses a suspension of small, elastomer spheres — between 50 to 500 microns — that buckle under pressure, radically changing the characteristics of the fluid. The meta-fluid could be used in everything from hydraulic actuators to program robots, to intelligent shock absorbers that can dissipate energy depending on the intensity of the impact, to optical devices that can transition from clear to opaque. …read more

These plants evolved in Florida millions of years ago: They may be gone in decades

These plants evolved in Florida millions of years ago: They may be gone in decades

Scrub mints are among the most endangered plants you’ve probably never heard of. More than half of the 24 species currently known to exist are considered threatened or endangered at the state or federal level. In a new study, researchers show there are likely more scrub mint species waiting to be scientifically described. And at least one species has been left without federal protection because of a technicality. …read more

Scientists link certain gut bacteria to lower heart disease risk

Scientists link certain gut bacteria to lower heart disease risk

Changes in the gut microbiome have been implicated in a range of diseases including type 2 diabetes, obesity, and inflammatory bowel disease. Now, a team of researchers has found that microbes in the gut may affect cardiovascular disease as well. The team has identified specific species of bacteria that consume cholesterol in the gut and may help lower cholesterol and heart disease risk in people. …read more

New materials discovered for safe, high-performance solid-state lithium-ion batteries

New materials discovered for safe, high-performance solid-state lithium-ion batteries

All-solid-state lithium-ion batteries offer enhanced safety and energy density compared to liquid electrolyte counterparts, but face challenges like lower conductivity and insufficient electrode contact. In a recent study, scientists have discovered a stable, highly conductive lithium-ion conductor in the form of a pyrochlore-type oxyfluoride. This innovation addresses the need for non-sulfide solid electrolytes, offering higher conductivity and stability and paves the way for advanced all-solid-state lithium-ion batteries with improved performance and safety. …read more

Gloom and doom warnings about climate change do not work

Gloom and doom warnings about climate change do not work

How do you spread a message about climate change? According to an international study involving 59,000 participants, some tactics may actually reduce support. …read more

Infant gut microbes have their own circadian rhythm, and diet has little impact on how the microbiome assembles

Infant gut microbes have their own circadian rhythm, and diet has little impact on how the microbiome assembles

Infant gut microbiomes oscillate with a circadian rhythm, even when they are cultivated outside of the body. Researchers report that the rhythm is detectable as early as 2 weeks after birth but becomes more pronounced with age. The finding comes from a randomized controlled trial that also showed that diet has less impact on the development and composition of the infant microbiome than previously thought. …read more

Engineers ‘symphonize’ cleaner ammonia production

Engineers ‘symphonize’ cleaner ammonia production

Among the many chemicals we use every day, ammonia is one of the worst for the atmosphere. The nitrogen-based chemical used in fertilizer, dyes, explosives and many other products ranks second only to cement in terms of carbon emissions, due to the high temperatures and energy needed to manufacture it. But by improving on a well-known electrochemical reaction and orchestrating a ‘symphony’ of lithium, nitrogen and hydrogen atoms, engineers have developed a new ammonia production process that meets several green targets. …read more
