One in four older adults take aspirin at least three times a week, mostly in hopes of preventing heart attacks and strokes, a new poll shows. But many people aged 50 to 80 who said they take aspirin may not need to, the findings from the University of Michigan National Poll on Healthy Aging suggest. In all, 57% of people aged 50 to 80 who say they take aspirin regularly also said they don’t have a history of cardiovascular disease. Such people should have a conversation with their health care provider about what’s best for them before stopping or starting aspirin use. National guidelines have changed in recent years for using aspirin for prevention, ...

Antimicrobial resistance is a story of constantly moving parts and players. With every new or tweaked antibiotic or antimicrobial drug, the targeted pathogens begin the evolutionary dance of acquiring resistance, prompting researchers to constantly develop workarounds or entirely new classes of medicine. Understanding the underlying mechanisms of acquired antimicrobial resistance is critical to the fight, a case of knowing one’s enemy. In a new paper published March 2, 2024 in npj Antimicrobials and Resistance, part of the Nature Portfolio, researchers at Sanford Burnham Prebys, working with Roche Pharma Research and Early Development, ...

Before a robot can grab dishes off a shelf to set the table, it must ensure its gripper and arm won’t crash into anything and potentially shatter the fine china. As part of its motion planning process, a robot typically runs “safety check” algorithms that verify its trajectory is collision-free.  However, sometimes these algorithms generate false positives, claiming a trajectory is safe when the robot would actually collide with something. Other methods that can avoid false positives are typically too slow for robots in the real world. Now, MIT researchers have developed a safety check technique which can prove with 100 percent accuracy ...

For the first time, neuroscientists have established a link between shifts in our visual perception and the cadence of our steps while walking. The research, published in Nature Communications, shows that the brain processes vision in a rhythmic manner, rising and falling in sensitivity in a cycle that corresponds to the rhythm of our steps. When swinging from one step to the next, human perception is good and reactions fast. During footfall, however, our vision is not as sharp and reactions are slowed. Lead author Dr Matthew Davidson from the School of Psychology at the University of Sydney said: “This work reveals a previously unknown relationship between perception ...
