Designing cities for 21st-century weather

Researchers have investigated how changes in urban land and population will affect future populations' exposures to weather extremes under climate conditions at the end of the 21st century. They used a data-driven model to predict how urban areas across the country will grow by 2100, and found that how a city is laid out or organized spatially has the potential to reduce population exposures to...

Yucatán's underwater caves host diverse microbial communities

With help from an experienced underwater cave-diving team, researchers have constructed the most complete map to date of the microbial communities living in the submerged labyrinths beneath Mexico's Yucatán Peninsula. Researchers found the cave system's microbiome is distinct from the nearby sea, and microbial communities vary between cave systems forming distinct 'neighborhoods.'  

A closer look at rebel T cells

New research sheds light on the genes and nutrients that give MAIT cells their fighting power. The findings are an important step toward one day harnessing these cells to treat infectious diseases and improve cancer immunotherapies.

Low-intensity fires reduce wildfire risk by 60%

High-intensity, often catastrophic, wildfires have become increasingly frequent across the Western U.S. Researchers quantified the value of managed low-intensity burning to dramatically reduce the risk of such fires for years at a time.

quantum mechanics: Unlocking the secrets of spin with high-harmonic probes

Deep within every piece of magnetic material, electrons dance to the invisible tune of quantum mechanics. Their spins, akin to tiny atomic tops, dictate the magnetic behavior of the material they inhabit. This microscopic ballet is the cornerstone of magnetic phenomena, and it's these spins that a team of researchers has learned to control with remarkable precision, potentially redefining the...

Unlocking the secrets of spin with high-harmonic probes

Deep within every piece of magnetic material, electrons dance to the invisible tune of quantum mechanics. Their spins, akin to tiny atomic tops, dictate the magnetic behavior of the material they inhabit. This microscopic ballet is the cornerstone of magnetic phenomena, and it's these spins that a team of JILA researchers—headed by JILA Fellows and University of Colorado Boulder professors...

NASA's Mars fleet will still conduct science while lying low

NASA will hold off sending commands to its Mars fleet for two weeks, from Nov. 11 to 25, while Earth and the Red Planet are on opposite sides of the sun. Called Mars solar conjunction, this phenomenon happens every two years. The missions pause because hot, ionized gas expelled from the sun's corona could potentially corrupt radio signals sent from Earth to NASA's Mars spacecraft, leading to...

‘An exciting time’: US eye operation is just latest leap forward for transplants

Boundary-pushing 21-hour surgery follows series of extraordinary advances including pig heart transplantsUS surgeons have announced the world’s first whole-eye transplant after a boundary-pushing 21-hour surgery. While the 46-year-old patient, Aaron James, cannot yet – and may never – see through his new eye, the organ is showing signs of health and even this partial success takes...

Divergent mechanisms of reduced growth performance in Betula ermanii saplings from high-altitude and low-latitude range

Plant species are distributed in their preferred climatic zones, and plants growing at the edge of their natural distribution range often exhibit poor growth when relocated to a different environment. This phenomenon has been attributed to two factors: 1) the environment at the edge of the distribution is extreme for the species, causing them to lose their adaptive ability in a different...

Hera asteroid mission completes acoustic testing

ESA's Hera asteroid mission has completed acoustic testing, confirming the spacecraft can withstand the sound of its own lift-off into orbit. Testing took place within the Agency's Large European Acoustic Facility at the ESTEC Test Center in the Netherlands. This is Europe's largest and most powerful sound system, fitted with a quartet of noise horns that can generate more than 154 decibels of...
