The idea that dinosaurs were already in decline before an asteroid wiped most of them out 66 million years ago may be explained by a worsening fossil record from that time rather than a genuine ...

Scientists have attempted to map the human cell since the first microscope was invented more than 400 years ago. But many components of the cell still remain uncharted. "We know each of the proteins ...

About 66 million years ago, an asteroid slammed into the planet, wiping out all non-avian dinosaurs and about 70% of all marine species. But the crater it left behind in the Gulf of Mexico was a ...

Every galaxy is thought to form at the center of a dark matter halo. Stars are formed when gravity within dark matter halos draws in gas, but astrophysicists don't know whether star-free dark matter ...

Researchers discovered the blood vessels at the back of the eye -- called retinal microvasculature -- can show early signs someone is at risk of developing dementia.

While the daily ebb and flow of people across a city might seem chaotic, new research reveals underlying universal patterns. A study unveils fundamental spatiotemporal scaling laws that govern these ...

Organoids are made to model human organs and are promising for research and therapy, but there are limitations in their growth and function. A recent study found that placenta-derived IL1 under ...

Just steps from the center of Tikal, a 2,400-year-old Maya city in the heart of modern-day Guatemala, a global team of researchers has unearthed a buried altar that could unlock the secrets of a ...

A new way to watch catalytic reactions happen at the molecular level in real time could lead to better fundamental understanding and planning of the important reactions used in countless manufacturing ...

Although sedentary behavior may be an evolutionarily selected trait, it is still important to try to be physically active, says a new study. Researchers have shown for the first time that genetic ...

Experimental drug NU-9 -- a small molecule compound approved by the U.S. Food and Drug Administration (FDA) for clinical trials for the treatment of amyotrophic lateral sclerosis (ALS) -- improves ...
