This pulsating muscle graft mimics benefits of exercise
Researchers have created contracting muscle implants that can mimic some of the benefits of exercise, including improving muscle mass, strength and bone density while also slowing age-related muscle changes.
New artificial lung mimics breathing and alveolar movement
Almost everyone has blown a soap bubble through a straw at least once. Inspired by this thin soap bubble film, an "artificial lung that breathes" like a real lung has been developed.
Depression may shut down the brain’s ability to make new neurons
A major study found that adults with depression show disrupted production of new neurons in the hippocampus, potentially weakening the brain’s ability to separate new experiences from painful memories. The researchers also identified broad molecular changes that could open the door to new treatments tailored to different biological forms of depression.
Next-Gen mRNA Delivery System Could Lead to Longer-Lasting Treatments
Researchers at Nagoya University in Japan, in collaboration with FUJIFILM Corporation, have developed a lipid nanoparticle (LNP) designed to deliver circular RNA (cirRNA) into cells. The approach could support development of longer-lasting mRNA-based therapeutics, including cancer vaccines and treatments that use glucagon-like peptide-1 (GLP-1).
We do not have a decider in our brain: An IU cognitive neuroscientist challenges theories of decision-making
In this theory, in place of a discrete decision-making function in the brain that causes actions, a combination of sensory, sensorimotor, and motor processes leads to ‘action selection’ and it is based on a less linear, more simultaneous and circular interaction between body, brain, and environment – a feature which calls for a shift in scientific methods that can capture this dynamic.
Catalyzing the Community: Chemists, Navajo Leaders Educate on Clean Water | Newswise
In partnership with the Navajo Nation, Jani Ingram and team measured heavy metals in well water on tribal lands. The team and tribal leaders developed best practices for distributing safe drinking water resources to residents on Navajo reservations. They will present their results at ACS Fall 2026.
Vagus nerve stimulation may enhance long-term motor learning
Do you ever feel like sometimes you can master a new dance step almost immediately, while other times you struggle to nail it despite repeated practice? This might be due to skill or effort, but also to something less obvious: whether the brain is in a state that allows learning to take hold.
Scientists may have found a shortcut to calorie restriction’s anti-aging benefits
Moderate calorie restriction lowered an immune protein called C3 that appears to help drive chronic inflammation as the body ages. Blocking the same protein reduced age related inflammation in mice, raising the possibility that future treatments could mimic some benefits of calorie restriction without severe dieting.
First robot for drawing blood authorized by FDA
Vitestro has received authorization from the U.S. Food and Drug Administration (FDA) for its robotic blood drawing device, Aletta. This is the first tool of its kind.
Considerations for the Regulation of Generative AI-Enabled Medical Devices: Discussion Paper and Request for Feedback
Herein, the Digital Health Center of Excellence (DHCoE), within the FDA’s Center for Devices and Radiological Health (CDRH), is leading a discussion paper on “Considerations for the Regulation of Generative AI-Enabled Medical Devices.”
