That finding comes from analyzing the footprints these theropods left behind as they dashed over squishy lake bed mud tens of millions of years ago. Two sets of fossilized footprints at a site in La Rioja, Spain show that the makers of the tracks were galloping along at speeds up to 27.7 mph (44.6 km/h), reaching "some of the top speeds ever calculated for theropod tracks," according to the new study.

In a recent study, posted to the preprint database bioRxiv on Oct. 25, scientists experimented with fat tissue obtained from bariatric surgeries, to see if the tissue could be infected by the coronavirus. They found that fat cells, known as adipocytes, could become infected and developed a low level of inflammation. They also found that immune cells housed within the fat tissue, called macrophages, also became infected and kicked off a much more intense inflammatory response.

Manhattan District Attorney (DA) Cyrus Vance, Jr. said in a statement that Michael Steinhardt, the 81-year-old founder of Steinhardt Partners and former chairman of the board of WisdomTree Investments, "displayed a rapacious appetite for plundered artifacts without concern for the legality of his actions, the legitimacy of the pieces he bought and sold or the grievous cultural damage he wrought across the globe."

Knowing how and why water transforms into ice is essential for understanding a wide range of natural processes. Climate fluctuations, cloud dynamics and the water cycle are all influenced by water-ice transformations, as are animals that live in freezing conditions.

It was 10 times larger than any ever seen.]( (NASA/Goddard Space Flight Center) A baby version of the sun recently let off an eruption of magnetic plasma gas 10 times larger than any ever seen from a sun-like star, according to new research. The star, EK Draconis, is only about 100 million years old, meaning it looks like Earth's sun about 4.5 billion years ago, said study leader Yuta Notsu, a research associate at the Laboratory for Atmospheric and Space Physics at the University of Colorado, Boulder. The findings suggest the sun is capable of belching out coronal mass ejections (CMEs) — bubbles of plasma gas — larger than any directly observed so far. However, because the sun is older than EK Draconis, it's likely to be calmer, with enormous CMEs occurring fewer and farther between.

We need them for biting and chewing, but our teeth also ensure our jaw develops properly and aid speech. Not looking after our teeth can cause tooth decay and gum disease, leading to the removal of the offending teeth. And although they may resemble bones, what are they really? We take a closer look at what teeth are made of, the different types of teeth and whether we can do without any of them.
