Insurmountable: The Efforts to Bring the Salmon Run Home

Workers seen on top of the cliff at the Big Bar landslide on the Fraser River in July 2019. Fisheries and Oceans Canada officials said that 99 per cent of early Stuart sockeye and 89 per cent of early chinook salmon were lost that year. The fish couldn’t make it past the landslide.

How Does Time Work?

There are two main ways of measuring time: dynamic and atomic time. The former relies on the motion of celestial bodies, including Earth, to keep track of time, whether it's the rotation time of a distant spinning star such as a pulsar, the motion of a star across our night sky or the rotation of Earth.

Bird With A Twenty Foot Wing Span

“Our fossil discovery, with its estimate of a 5-to-6-meter wingspan — nearly 20 feet — shows that birds evolved to a truly gigantic size relatively quickly after the extinction of the dinosaurs and ruled over the oceans for millions of years,” said first author Peter Kloess, a graduate student at the University of California (UC), Berkeley.

A History Of The First Computers

A machine that took up an entire room at a laboratory in Manchester University ran its first program at 11am on 21 June 1948. The prototype completed the task in 52 minutes, having run through 3.5 million calculations. The Manchester Baby, known formally as the Small-Scale Experimental Machine, was the world's first stored-program computer.

When washed down the drain, glitter becomes a subset of marine plastic litter known as microplastic. Microplastics, which measure less than five millimeters in length, are found throughout the world’s oceans, from the surface to the deep sea floor. They are consumed by plankton, fish, shellfish, seabirds, and other marine life.

Scuba Diving Fly

Researchers at Caltech found that like other flies, alkali have small hair-like structures and a coating that lets water slip off their back. But unlike other flies (including kelp flies and fruit flies), these insects have more ‘hairs’ and an even more water-repellent coating. The combination means that the flies can trap a small bubble of air around them as they squiggle their way underwater.

Are Aliens Trying To Contact Us?

“Although unlikely, there is also a possibility that the signals are due to highly peculiar chemical compositions in a small fraction of galactic halo stars.” said Trottier and Borra.

7 Earth-Size Planets Discovered

The length of each planet’s day — how quickly it spins on its axis — may sync with its sun’s orbit. That would make the innermost planet’s day 1.5 Earth days long and the outermost one’s 20 Earth days long. That would be like Earth rotating once in 365 days instead of in 24 hours.

The discovery may overturn ideas of when relatively advanced life evolved, say scientists in Sweden.

Space Junk

Dana Arabiyat, 15, of Amman, Jordan, designed a satellite to collect and dispose of the space trash that threatens other satellites orbiting Earth.

Dark Matter Is Not as Sticky

The leading theory is that dark matter particles spread throughout the galaxy clusters do not frequently bump into each other. The reason the dark matter doesn't slow down is because not only does it not interact with visible particles, it also infrequently interacts with other dark matter. The team has measured this "self-interaction" and found it occurs even less frequently than previously thought.

"Standing workstations reduce disruptive behavior problems and increase students' attention or academic behavioral engagement by providing students with a different method for completing academic tasks (like standing) that breaks up the monotony of seated work. School districts that put standing desks in classrooms may be able to address two problems at the same time: academic performance and childhood obesity.
