Is the random motion of particles suspended in a medium (a liquid or a gas). [ 2 ] The traditional mathematical formulation of Brownian motion is that of the Wiener process, which is often itself called “Brownian motion”, even in mathematical sources.
Hormone therapy use among women in the U.S. remains low, even though it’s an effective treatment for many menopause symptoms, according to a new Mayo Clinic study published in Mayo Clinic Proceedings.
Menopause affects more than one million women each year in the U.S., and up to 75% experience symptoms such as hot flashes and night sweats that can last for years. Yet researchers have found that use of menopausal hormone therapy has steadily declined over time.
The new study found that hormone therapy use dropped from 4.4% in 2007 to 1.7% in 2023. Even among women most likely to benefit—those ages 50 to 59—only about 3.5% were using hormone therapy in 2023.
I had Tom Benson, CEO of Mitrix on to discuss mitochondrial transplantation. We covered what mitochondria are, the discovery that your body is constantly delivering fresh mitochondria through your bloodstream (people didn’t know that mitochondria were transferred outside the cell until recently!), why we age, what kills mitochondria (stress, smoking, radiation, chemotherapy and certain antibiotics like fluoroquinolones, psych meds), why COVID destroys mitochondria and what that means for long COVID, the Alzheimer’s and Parkinson’s brain tissue regeneration research their company has already done in mice, what mitochondrial transplantation actually is and how it has already been used in pediatric heart surgery, what a bioreactor growing mitochondria for personal use might look like, and more.
The drug rilmenidine is usually taken to treat hypertension, but its powers appear to go far beyond that.
In fact, research shows rilmenidine can slow aging in worms – an effect that, if it translates to humans, could one day help us live longer and stay healthier in old age.
Rilmenidine appears to mimic the effects of caloric restriction on a cellular level, and reducing available energy while maintaining nutrition has been shown to extend lifespans in several animal models.
Buildings account for 30–40 percent of global energy expenditure and more than half of global electricity consumption. But the most advanced smart buildings—those with full automation, AI controls, and on-site generation—can achieve energy reductions of 50–70 percent. Scaled across the built environment, that translates to 60–110 exajoules of energy saved per year—that’s more than the entire current energy consumption of the United States, or the total output of all the world’s nuclear power plants combined.
Transforming the buildings we already live and work in to become a part of the system itself that generates, stores, and manages energy efficiently could be the blueprint for the future of energy use, creation, and management.
Mice wearing specialized goggles reveal that the brain’s internal visual networks rewire themselves to match the exact patterns they see in the world. The study shows how visual feedback loops actively learn to predict our surroundings.
If the future of warehouse work belongs to humans and robots working side by side, a key question remains: What is the most effective way for them to collaborate?
Research published in Transportation Science suggests that the answer may be more flexible than many warehouse operators expect. The study, “Picking the Best Bot: Collaboration Strategies for Humans and Bots in Order Pick Systems with Traveling Salesman Problem Routing,” found that under many real-world conditions, warehouse workers achieve higher productivity when they dynamically switch among multiple autonomous mobile robots rather than work exclusively with a single robot.
The findings challenge a common assumption that fixed human–robot pairings are the most efficient approach.
