After two years, people who underwent sleeve gastrectomy or gastric bypass lost about five times more weight than those using weekly GLP-1 receptor agonists such as semaglutide or tirzepatide,* according to research…

Japanese scientists just built human brain circuits in the lab

A research team in Japan has successfully recreated key human neural circuits in the laboratory using tiny, multi region brain models called assembloids. These structures are grown from induced pluripotent stem (iPS) cells and are designed to mimic how different parts of the human brain connect and communicate. Using this…

A global cancer surge is underway and the world is not ready

Cancer cases are exploding worldwide — and nearly half of the deaths could be prevented with better prevention, early detection, and access to care. New cancer cases worldwide have more than doubled since 1990, reaching 18.5 million in 2023. Over the same period, annual cancer deaths rose by 74 percent…

Breakthrough lets scientists watch plants breathe in real time

Scientists have long understood that plants take in air through tiny openings on their leaves known as stomata. These microscopic pores act like adjustable valves, letting carbon dioxide enter the leaf for photosynthesis while allowing water vapor to escape into the air. Until now, closely tracking this balancing act as…

Wildfires are polluting the air far more than thought

As wildfires move across forests, grasslands, and peatlands, they release large amounts of gases and particles into the air. Scientists now say the pollution from these fires may have been underestimated. A study published in ACS’ Environmental Science & Technology reports that wildfires and prescribed burns (i.e., wildland fires) around…
