For years, calcium and vitamin D supplements have been promoted as a simple way for older adults to protect their bones and prevent falls. But a massive review of nearly 154,000 people found that calcium, vitamin D, or a combination of both provided little to no meaningful protection against fractur…
Researchers used genome editing to block the production of red pigments in lettuce, causing other beneficial plant compounds to build up instead. The lettuce continued to grow normally, pointing toward a new way to create crops with customized nutritional profiles.
A new whey protein manufacturing technique could make protein shakes taste better and feel smoother in the mouth. Researchers traced unwanted bitterness to concentrated minerals and found a way to remove them without sacrificing the improved texture.
Researchers tracked honey bees in the wild using a drone-based system and found that each bee follows its own highly consistent flight path. Some repeated their routes so precisely that they flew only centimeters from where they had flown before. Landmarks like trees helped keep them on track, while…
NASA satellites have detected a vast pulse of warm water reaching the coast of South America, signaling that El Niño is likely developing. The warm water is being carried eastward by massive ocean waves known as Kelvin waves, which also cause sea levels to rise. El Niño can reshape weather patterns …
A large-scale study suggests that men with higher levels of the amino acid tyrosine may have shorter lifespans, potentially losing close to a year of life expectancy. The finding is especially intriguing because tyrosine is commonly associated with brain health and is often used in supplements aimed…
Scientists have found that staple-shaped particles can tangle together to create a material that is both strong and flexible. Unlike conventional materials, these particles can be locked into a sturdy structure or rapidly unraveled using vibrations. The unusual behavior could open the door to recycl…
