Independent U.S. science funder
JWST limb-resolved spectroscopy reveals a cloudy morning limb and a clearer evening limb on tidally locked exoplanet WASP-94A b, implying strong day-night circulation and challenging past assumptions about uniform planetary atmospheres.
The Justice Department has reached a settlement with former President Donald Trump over an IRS controversy. The deal bars audits of Trump, his family, and affiliates for existing tax matters and establishes an $1.8 billion anti-weaponization fund for allies; the arrangement covers only existing audits, not future ones.
The European Union has announced a substantial investment in ocean observation, positioning Europe at the forefront of marine monitoring as the United States proceeds with the dismantling of the Ocean Observatories Initiative. The NSF has begun a descope of the OOI, pulling instruments from multiple U.S. sites while the EU commits hundreds of millions to expand global ocean data networks.
The National Science Foundation has halted plans to remove or descale the Ocean Observatories Initiative, after lawmakers and scientists warned of risks to climate data, weather forecasts and coastal safety. An expert panel will assess future needs while equipment already removed will be redeployed. The move follows bipartisan pressure and a Senate bill to block decommissioning.
El Niño has formed in the Pacific and is expected to strengthen through late 2026, with a 63% chance of reaching a very strong level. Forecasts warn of hotter global temperatures and extreme weather, while impacts will vary by region. Scientists urge preparation and climate action as nations monitor evolving conditions.
AI models are delivering faster pattern recognition and higher accuracy for hurricane forecasts, with NOAA citing a 15-30% improvement over traditional methods. DeepMind and other labs are expanding high‑resolution data use to sharpen predictions and enable earlier evacuations.
The Vera C. Rubin Observatory has begun the Legacy Survey of Space and Time, a 10-year program that will image the southern sky every few nights. The telescope has started regular operations from its Chilean mountaintop site and is already returning new detections, including thousands of asteroids and transient views such as Comet 3I/ATLAS.
Solar scientists using the Inouye Solar Telescope in Hawaii have captured unprecedented, sub-20-km features on the Sun’s surface, identifying Kelvin-Helmholtz instabilities that may explain corona heating and energy transfer driving space weather. Findings published in Nature underscore how magnetic energy moves upward, fueling flares and coronal mass ejections.
Airbus A319 Long Range flew from Hobart to McMurdo on July 31 to evacuate an American patient; landing occurred in darkness at -43 C, with a transfer to Christchurch for treatment. The operation highlights civilian capability and international cooperation in Antarctic medicine.
