NASA announced a public-private partnership with Relativity Space for the Aeolus Mars atmospheric science mission, with NASA providing the instrument suite and Relativity Space supplying spacecraft, rocket, and cruise operations for a planned 2028 launch.^[1]

Two independent research teams at Tsinghua University and the Vienna Center for Quantum Science and Technology have achieved a longstanding physics goal by building working nuclear clocks, which exploit thorium-229 nuclei to potentially surpass the precision of today's best atomic clocks.^[2]

Stanford Medicine researchers developed a treatment that blocks an aging-related protein, successfully regrowing cartilage in old mice and helping prevent arthritis after knee injuries, with human cartilage samples showing similar signs of regeneration.^[3]

Researchers at Monash University found that a copper-based drug reduced buildup of toxic Alzheimer's proteins and improved long-term spatial memory in laboratory experiments, with the drug already tested in humans for other neurological conditions.^[4]

SETI Institute researchers published findings suggesting that alien radio signals may have reached Earth but gone undetected because interstellar plasma scatters narrowband transmissions, broadening them beyond the frequencies traditional searches monitor.^[5]

New analysis of two gamma-ray bursts indicates that kilonova light can arise from collapsing stars rather than neutron-star mergers, suggesting kilonovae may form without producing the heaviest r-process elements like gold and lead.^[6]

NASA satellite observations confirm El Niño made its return in June 2026, with conditions in the western Pacific resembling those from 1997 when an exceptionally strong El Niño emerged, though whether it reaches similar intensity depends on ocean activity in coming weeks.^[7]

A new oral GLP-1 medication called elecoglipron significantly lowered blood glucose levels and reduced body weight in people with type 2 diabetes in a major clinical trial, with results published simultaneously in The Lancet.^[8]

Vice President JD Vance announced that more than 12.5 million barrels of oil passed through the Strait of Hormuz overnight, the highest level since the US-Iran conflict began in late February, following the signing of a memorandum of understanding between Washington and Tehran.^[9]

Researchers at Nature Communications generated an isogenic collection of 65 genome-edited human pluripotent stem cell lines with mutations in 11 Parkinson's disease genes, creating a resource that enables controlled comparisons and improved disease modeling.^[10]
