Physicists shine new light on ultra-fast atomic processes      (via sciencedaily.com)     Original source 

Scientists report incredibly small time delays in a molecule's electron activity when the particles are exposed to X-rays. To measure these tiny high-speed events, known as attoseconds, researchers used a laser to generate intense X-ray flashes that allowed them to map the inner workings of an atom.

Chalk-based coating creates a cooling fabric      (via sciencedaily.com)     Original source 

In the scorching heat of summer, anyone who spends time outside could benefit from a cooling fabric. While there are some textiles that reflect the sun's rays or wick heat away, current options require boutique fibers or complex manufacturing processes. But now, demonstrations of a durable chalk-based coating show it can cool the air underneath treated fabric by up to 8 degrees Fahrenheit.

Pilot study uses recycled glass to grow plants for salsa ingredients      (via sciencedaily.com)     Original source 

Tortilla chips and fresh salsa are tasty, but they could be even more appealing if you grow the ingredients yourself. Now, researchers report that some salsa ingredients -- cilantro, bell pepper and jalapeno -- can be more sustainably cultivated with recycled glass. Their pilot study found that partially substituting soil in a planter with recycled glass fragments speeds up plant development and reduces unwanted fungal growth.

Survival tactics: AI-driven insights into chromatin changes for winter dormancy in axillary buds      (via sciencedaily.com)     Original source 

Epigenetics confers a survival advantage in plants to endure harsh weather by inducing bud dormancy. Environmental factors or intrinsic signals trigger the transition between growth and dormancy. Researchers explore the role of chromatin and transcriptional changes in the bud and further analyze data using artificial intelligence models. The findings of this study highlight epigenetic strategies to overcome the effects of short winters during global warming for plant survival.

Expanding a child's heart implant with light      (via sciencedaily.com)     Original source 

Children born with certain heart defects undergo a series of invasive surgeries early in life. The first surgery includes implantation of a shunt to improve blood flow. However, as children grow, the shunt must be replaced to accommodate their changing bodies. Now, researchers report designing a shunt that expands when activated by light. This device could reduce the number of open-chest surgeries these children receive.

Study reveals urban trees suffer more from heat waves and drought than their rural counterparts      (via sciencedaily.com)     Original source 

A recent study details how trees in New York City and Boston are more negatively impacted by heat waves and drought than trees of the same species in nearby rural forests. The finding highlights the challenges urban trees face in the context of climate change and underscores the importance of tailored urban forestry management as a tool for protecting tree species and reducing urban heat islands.
