NASA Selects Next Class of Space Health Postdoctoral Fellows

- NASA-funded TRISH selected two early‑career scientists for its next postdoctoral class, starting projects in May. - Dr. Baiyang Liu (Columbia University) will develop a diazotrophic, nutritionally optimized spirulina strain for extended space missions. - Dr. Dylan Pham (Texas A&M) will study effects of simulated microgravity and aging on ocular artery and neural retina function. - TRISH’s fellowship program supports independent research to reduce spaceflight health risks and advance biomedical, behavioral, and technological solutions for human exploration.

NASA Satellites Uncover Large-Scale Ocean Nutrient Stress

NASA Satellites Uncover Large-Scale Ocean Nutrient Stress

- A study published June 5 (Science Advances) combines two decades of NASA MODIS satellite data, ocean surveys, and genetic markers in Prochlorococcus to map phytoplankton nutrient stress globally. - Warming sea-surface temperatures increase stratification, reduce upwelling, and limit surface nutrients, with strongest stress in subtropical gyres and the South

Fighting Fire With Fire

Fighting Fire With Fire

- NASA’s Aqua/MODIS imagery captured smoke from numerous fires in Australia’s Northern Territory on May 28, 2026. - Many detected fires are deliberate prescribed burns, typically lit in mornings to manage savanna fuel loads. - Indigenous practices and modern programs (e.g., WALFA, Arnhem Land Fire Abatement)

NASA-Funded Study Shows Wildfire Smoke’s Hidden Ozone Toll

NASA-Funded Study Shows Wildfire Smoke’s Hidden Ozone Toll

- A NASA-supported study found that over the past decade wildfires have increased ground-level ozone (smog) across much of the contiguous U.S., worsening air quality far from fires. - Nationally, fires offset nearly four years of ozone-control gains; in the Midwest wildfires erased about 5.3 years of progress
