High‑altitude hypoxia curbs blood‑sugar spikes in mice
A mouse study found that low‑oxygen (hypoxic) conditions cause red blood cells to absorb far more glucose and convert it into a molecule that eases oxygen release, acting as a glucose sink. Mice exposed to 8% oxygen showed markedly smaller blood‑sugar spikes after glucose injections, and the effect persisted after they returned to normal air.
University of Washington researchers have developed a recyclable composite that embeds microscopic gallium‑based liquid‑metal droplets in a stretchable polymer. The material can be patterned into functional circuits by scoring its surface, self‑heals after cuts, and can be chemically dissolved to reclaim 94 % of the metal for reuse. Its flexibility and reconfigurability make it a promising platform for wearable devices, soft robotics, and next‑generation circuit boards. The work, published in Advanced Functional Materials, was supported by the NSF and the Department of Energy.
Researchers have confirmed a super‑Earth, GJ 887 d, orbiting within the habitable zone of the nearby M‑dwarf GJ 887, only 10.7 light‑years from Earth. The planet, with a minimum mass about six times Earth’s and a 51‑day orbital period, is the second known...
Engineers at the University of Maine have introduced a hybrid method that blends advanced nonlinear finite‑element modeling with physical testing to predict the strength of gyroid‑infilled 3D‑printed parts. The approach outperforms traditional linear analyses by capturing plastic deformation and anisotropic...

Carolyn Porco, born March 6, 1953, rose from a doctoral candidate in earth and space sciences to become a leading planetary imaging scientist. She joined the Voyager team in the early 1980s and co‑planned the iconic 1990 “Pale Blue Dot” photograph with...
Researchers at the University of Melbourne have unveiled the world’s first laboratory‑based, host‑free feeding platform for the Asian longhorned tick (Haemaphysalis longicornis). The silicone‑membrane system, using defibrinated cattle blood, supports full feeding and reproduction without live animal hosts. This breakthrough...
Researchers have identified flavin‑containing monooxygenase‑2 (FMO‑2) as a shared downstream effector in several long‑lived mitochondrial mutants of Caenorhabditis elegans, including clk‑1, isp‑1 and nuo‑6. RNA interference or genetic loss of fmo‑2 shortens the extended lifespan of these mutants, confirming its...

China’s new five‑year plan lowers its carbon‑intensity goal to a 17% cut between 2026 and 2030, a step back from the 18% target for 2021‑2025 that it already missed. Analysts warn the weaker pledge could let national emissions rise 3‑6%...
Asteroid 2024 YR4, a 60‑metre near‑Earth object, once carried a 4 % chance of striking the Moon in December 2032. New observations with JWST’s NIRCam in February 2026 precisely measured its orbit, eliminating the lunar‑impact risk. The asteroid will safely miss the Moon by...
Psychedelic antidepressants are poised for FDA review this year, driven by strong investor and patient interest. William Blair analysts note that while Johnson & Johnson’s Spravato generated $1.7 billion in 2025 sales, psychedelics are unlikely to capture the entire treatment‑resistant depression market. Companies...
