Researchers directly observed muscle actin filaments growing from an end long thought unable to support growth, revealing how the protein leiomodin 2 helps maintain their structure. Muscle cells face a peculiar problem. Their actin filaments must remain precisely the right length for muscles to contract properly, yet those same filaments continually age, degrade, and need […]

Bats Have a Secret Immune System Scientists Have Never Seen in Any Other Mammal
Vesper bats possess a second antibody gene system unseen in other known mammals, revealing a new level of immune diversity. Bats can harbor viruses capable of causing severe disease without usually becoming seriously ill themselves, a biological puzzle that has challenged scientists for years. Researchers at Tulane University, working with collaborators at Stanford University and […]
A Star’s Spin Could Solve a Longstanding Black Hole Mystery
A star’s rotation may help solve a longstanding mystery involving repeated encounters between stars and supermassive black holes. At the center of most galaxies sits a supermassive black hole, an object millions to billions of times more massive than the Sun. Its gravity is powerful enough to tear apart a star that ventures too close, […]

NASA Is Building “Air Traffic Control” for the Moon
As NASA prepares for humanity’s first lunar spaceport, engineers are developing a traffic control system to keep spacecraft moving safely and efficiently. Within the next two decades, NASA’s planned Gateway could become humanity’s first lunar spaceport, serving Orion crew capsules, lunar landers, cargo vehicles, and astronauts traveling between Earth, the moon, and eventually farther into […]
NASA Finds Earth Microbes Could Hide in the Moon’s Deep Shadows
Microbes carried to space by human explorers could survive in shaded areas near the moon’s south pole, according to researchers from NASA and the University of Maryland. Even on the moon, where extreme temperatures and intense ultraviolet (UV) radiation make the surface deeply hostile to life, some microbes from Earth may find temporary refuge. New […]
New Study: Intermittent Fasting Lowers Blood Sugar in Type 1 Diabetes
A small trial suggests time-restricted eating may help adults with Type 1 diabetes lower blood sugar without increasing major safety risks. For adults with Type 1 diabetes, limiting food intake to a set eight-hour period each day may offer another way to manage blood sugar without counting calories. A UIC study led by kinesiology and […]
