Giant Iron Bar Discovered in Ring Nebula
Astronomers using the WEAVE instrument on the William Herschel Telescope found a huge iron structure inside the iconic Ring Nebula, revealed through detailed spectra across all optical wavelengths. This marks the first comprehensive chemical mapping of the nebula, showing iron's presence but needing further data on co-existing elements.
Follow-up observations at higher resolution are planned to explain its formation.
Viruses Evolve Differently in Space on ISS
Bacteria-infecting T7 phages sent to the International Space Station showed delayed infections and unique genetic mutations in microgravity compared to Earth. Space phages gained mutations boosting infectivity, while E. coli developed defenses suited to weightlessness.
These insights could enhance phage therapies against drug-resistant infections like UTIs.
New 'Fire Amoeba' Species Breaks Heat Records
Researchers discovered a new amoeba species at Lassen Volcanic National Park that survives and replicates at record high temperatures. Named for its extreme heat tolerance, it sets new benchmarks for microbial survival.
The find highlights extremophile diversity in volcanic environments.
Greenland Ice-Free 7000 Years Ago, Study Reveals
New research indicates large parts of Greenland were ice-free just 7,000 years ago, challenging models of ice sheet stability. This forces a rethink on rapid ice melt potential under warming climates.
The discovery comes from key geological evidence analyzed recently.
NVIDIA and Eli Lilly Launch $1B AI Drug Discovery Lab
NVIDIA and Eli Lilly announced a $1 billion AI co-innovation lab to revolutionize drug discovery workflows in oncology and beyond. This positions compute as core R&D infrastructure for precision medicine.
It signals growing pharma investment in AI for targeted therapies.
Spevatamig Shows Promise in Pancreatic Cancer Trial
The TWINPEAK study reported early efficacy for spevatamig (anti-CLDN18.2/CD47 bispecific) plus chemotherapy in CLDN18.2-positive metastatic pancreatic cancer. It aims to minimize GI and hematologic toxicities in first-line therapy.
No immunotherapy has yet been approved for this setting.
First Oral GLP-1 Medication Approved for Obesity
2025 saw FDA approval of the first oral GLP-1 receptor agonist for obesity treatment, expanding beyond injectables. These drugs mimic pancreatic hormones to aid weight loss and reduce heart disease risks.
They build on diabetes uses since the early 2000s.
Human Receives First Pig Lung Transplant
A brain-dead patient received the first pig lung transplant in 2025, surviving nine days post-operation. Published in Nature Medicine, it marks a milestone in xenotransplantation.
Further advancements could address organ shortages.
NASA Discovers New Interstellar Comet 3I/ATLAS
NASA identified Comet 3I/ATLAS in July 2025, the third known sizable interstellar object entering our solar system. Hubble data revealed unique compositions from outside our system.
It advances understanding of interstellar visitors.
NOAA Tests Ocean Alkalization to Combat Acidity
NOAA conducted a successful small-scale test in 2025 using electrodialysis to make seawater more alkaline, countering ocean acidification. This could scale up for climate mitigation efforts.
Larger tests are planned.
Polymer-Coated Fertilizer Pollutes Japanese Beaches
Tokyo Metropolitan University found 0.2% of polymer-coated fertilizers wash into Japan's rivers and beaches, rising to 28% near sea-connected canals. This identifies plastics as a significant ocean pollution sink.
Published in Marine Pollution Bulletin.
Flu Spread Halted by Airflow and Fewer Coughs
A breakthrough experiment demonstrates good airflow and reduced coughing prevent flu virus spread even in close proximity. This challenges assumptions about airborne transmission indoors.
Findings support ventilation strategies for respiratory viruses.
