NASA's Perseverance rover set a new record for the farthest distance driven on another world, reaching 28.10 miles (45.22 kilometers) on Mars, surpassing the record held by Opportunity for years. The rover achieved this milestone in just five and a half years, compared to Opportunity's nearly 15 years, thanks to its autonomous navigation system that has guided more than 90% of its journey.^[1]

Scientists at Columbia University and Imperial College London have confirmed that Valles Marineris, the largest canyon system in the solar system, is still tectonically active billions of years after it formed. Seismic data from NASA's InSight lander revealed a marsquake originated 20 to 40 kilometers beneath the vast Martian canyon, caused by rocks slipping along a deep fault.^[2]

Uzbekistan became the 77th nation to sign the Artemis Accords during a ceremony in Samarkand, committing to principles guiding safe and responsible civil space exploration. The signing took place during a visit by U.S. Secretary of State Marco Rubio and opens opportunities for Uzbekistan to expand cooperation with NASA and other international space agencies.^[3]

The U.S. Federal Aviation Administration certified the Boeing 737 MAX 10, the largest member of the 737 MAX family, after years of delays. The certification clears the way for Boeing to begin deliveries of the aircraft, which has more than 1,555 orders from over 30 customers, with commercial service expected in early 2027.^[4]

USC scientists discovered a method to create a potentially renewable supply of genetically engineered immune cells that can attack cancer and strengthen the body's natural defenses. By working with immature cells that can develop into immune defenders, researchers created a system capable of generating large numbers of tumor-fighting cells.^[5]

Mayo Clinic researchers discovered that fatty liver disease, affecting nearly 30% of adults worldwide, actually consists of five distinct biological subtypes, each carrying different risks for liver failure, cancer, heart disease, and other complications. The findings could lead to more personalized treatment approaches for the condition.^[6]

Voters in Canada's oil-rich Alberta province overwhelmingly rejected separation in a first-ever independence referendum, with approximately 76 percent voting to remain in Canada. The result delivers a boost to Prime Minister Mark Carney's push for national unity amid ongoing trade tensions with the United States.^[7]

The UN World Food Programme announced it will cut monthly food assistance to approximately 500,000 people in Gaza due to a funding shortfall, reducing recipients from 1.6 million to 1.1 million. The agency said it received less than half as much funding for its Palestine operation in 2026 as in previous years and urgently needs $450 million for the next six months.^[8]

Mount Sinai researchers identified three brain pathways linked to lasting improvements in people receiving deep brain stimulation for severe, treatment-resistant depression. The study also found that patients who failed to improve after two years shared a pattern of insufficient stimulation of a crucial brain connection, suggesting precise electrode placement could significantly affect treatment outcomes.^[9]

University of Vienna researchers discovered that the remarkable intelligence of octopuses, squid, and cuttlefish may trace back to an ancient reshuffling of their DNA that created new connections between genes. The changes in the genome's 3D structure may have helped drive the evolution of their unusually complex nervous systems.^[10]
