Federal budget cuts may force some states to end meal delivery for Medicaid patients
Some states deliver meals to Medicaid patients that address their dietary needs. Evidence shows it aids recovery and saves healthcare costs, but federal budget cuts may lead some states to cancel it.
New mesothelioma drug turns cancer’s own defenses against it
Scientists are testing a counterintuitive way to fight mesothelioma, an aggressive asbestos-linked cancer with few effective treatments. A new experimental mesothelioma drug kills cancer cells by disabling PRX3, an antioxidant defense that tumors use to survive intense oxidative stress. In an early clinical trial, it controlled disease progression in 67% of patients and produced encouraging survival results, raising hopes that the strategy could eventually be used against other cancers.

NASA’s New Horizons spots signs of liquid nitrogen flowing on Pluto
Scientists have found the first evidence that liquid may have flowed across Pluto’s surface in the recent past. Dark features on the enormous Sputnik Planitia glacier appear consistent with liquid nitrogen rising through cracks from deep beneath the ice. Computer models show that nitrogen could melt at the glacier’s base and travel upward like fluid through small conduits. The finding reveals that Pluto may be much more geologically active than its frozen appearance suggests.
Hidden “immune organ” in the skull may help fight brain cancer
Scientists discovered a hidden “immune organ” inside the skull that acts as a rapid first responder against brain cancer in mice. Strengthening this local immune defense improved tumor rejection and survival, raising the possibility of new treatments that target the skull directly.
