DART asteroid-smashing mission ‘on track for an impact,’ NASA says

NASA is just days away from slamming a spacecraft into an asteroid 7 million miles (11 million kilometers) from Earth. The agency’s long-awaited Double Asteroid Redirection Test (DART) mission will impact with the asteroid moonlet Dimorphos on Monday (Sept. 26), if all goes according to plan. The DART mission launched on Nov. 23, 2021 on … Read more

Funded by a four-year grant … Read more

Researchers track movement of charred detritus dispersed from Goleta Beach after 2018 debris flow in California

Mud and silt containing charred material and terrestrial plant matter was deposited on Goleta Beach shortly after the 2018 Montecito debris flow disaster. Credit: HE Lowman et al The catastrophic debris flow that affected Montecito, Calif., in early January, 2018 was the result of a rare confluence of severe events. The Thomas Fire had been … Read more

Why cycling lanes should be on the fast track for cities

Contrary to the urban myth, cycling lanes actually help ease traffic congestion. Credit: Shutterstock You might’ve noticed more cycleways rolling out around town recently. Whether it’s a designated path alongside a main street or spray-on white lines and traffic cones cordoning off a portion of a back street, these car-free paths for cycling fans are … Read more

Researchers track protein binding, build synthetic proteins to study gene expression

Credit: Unsplash/CC0 Public Domain How does a nose remember that it’s a nose? Or an eye remember that it’s an eye? As scientists probe the question of how cells remember what kind of cells they are supposed to be, or their genetic lineage, it’s important to understand how cells express different genes without changing the … Read more

NASA’s solar forecast is turning out to be wrong. This team’s model is still on track.

Solar cycle 25 kicked off last year. Forecasters thought it would be a mild one, but it’s turning out to be quite the opposite. From its onset, this solar cycle has been steadily outpacing predictions, producing more sunspots and spinning way more solar wind, flares and eruptions than the world’s leading experts predicted. But while … Read more

We helped track 77 species for up to 60 years to try to reveal the secrets of long life. Some don’t seem to age at all

Credit: Mike Gardner, author provided Ever wondered about the secret to a long life? Perhaps understanding the lifespans of other animals with backbones (or “vertebrates”) might help us unlock this mystery. You’ve probably heard turtles live a long (and slow) life. At 190 years, Jonathan the Seychelles giant tortoise might be the oldest land animal … Read more

International satellite to track impacts of small ocean currents

Credit: Pixabay/CC0 Public Domain The Surface Water and Ocean Topography mission will explore how the ocean absorbs atmospheric heat and carbon, moderating global temperatures and climate change. Though climate change is driving sea level rise over time, researchers also believe that differences in surface height from place to place in the ocean can affect Earth’s … Read more

Unchecked global emissions on track to initiate mass extinction of marine life

Princeton University researchers reported that unless greenhouse gas emissions are curbed, marine biodiversity could be on track to plummet to levels not seen since the extinction of the dinosaurs. The study authors modeled future marine biodiversity under projected climate scenarios and found that species such as dolphinfish (shown) would be imperiled as warming oceans decrease … Read more
