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.
The weather on this exoplanet includes metal clouds and rain made of precious gems.
Miniature Mars Rocket
This miniature rocket could be the first NASA craft launched from Mars.
Lockheed Martin will build the vehicle, which should only be about 10 feet tall. Eventually, NASA wants to literally throw it into the Martian atmosphere.
Finding Signs Of Alien Life
When it comes to looking for alien life, scientists mostly focus on where there is water. Now researchers suggest that looking at "bioessential" elements such as phosphorus and molybdenum could help judge a world's potential for life.
The growing amount of so-called "space junk" orbiting the Earth could lead to catastrophic collisions with satellites.
Watch the moment the UK-led RemoveDebris mission left the International Space Station (ISS).
Mars - One of the biggest mysteries of the universe is whether life may be possible beyond our home planet. Two announcements from NASA represent major steps forward in cracking that case.
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.
Olivine, a green mineral, is found inside lava erupting from fissures.
Cassini's Last Images Of Saturn
Three of Saturn’s moon are visible: Mimas (above the ring line), Janus (just touching ring line), and Tethys (below).

Bowhead whales, the black filter-feeding giants of the Arctic that can live for 200 years devouring tons of tiny marine creatures, boast another remarkable quality. Their unique underwater songs make them wonderful "jazz" artists.
Lupus 3, a dense cloud of gas and dust that collapses to create new stars.
GPS For Spaceships - The Stars
Spaceships could use blinking dead stars to chart their way.
Ban The Glitter
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.
An Unusual Planet
WASP-18b is an exoplanet located 325 light-years from Earth. The planet's mass is 10 times that of Jupiter, and it orbits its star once every 23 hours.
These soft robots cost less than a dollar and are built in minutes. Soft robotic muscles can give future robots a more human-like look, greater strength, and more versatility.
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.
Oldest Plants On Earth Found
The discovery may overturn ideas of when relatively advanced life evolved, say scientists in Sweden.
Black Holes Swallow Stellar Debris
In the center of a distant galaxy, almost 300 million light years from Earth, scientists have discovered a supermassive black hole that is "choking" on a sudden influx of stellar debris.
Scientists Discover Six New Species
Researchers found a new species of 'Hoff' crab, two snails, a limpet and two new species of worm.
U.S. Use Of Solar Power
U.S. sets staggering record with 191% growth in solar power installations in 2016.
World's Oldest Water Discovered
The vast age of the water is not the only important discovery. When the researchers analyzed the liquid, they found traces of life within it. While they are yet to find actual living bacteria, what they did discover was in effect the fingerprint of life.
48 New Volcanos Found On IO
There are plenty of weird volcanoes in our Solar System, from icy variants on dwarf planets to pancake volcanoes on Venus. On IO, though, they are utterly bonkers.
Cocoa Trees - How Old Are They?
Chocolate, produced from seeds of the cacao tree Theobroma cacao, is one of the most popular flavors in the world, with sales around 100$ billion dollars per year. Yet, as worldwide demand increases, there are fears the industry will fail to cope with growing public hunger for the product.
Citizen Scientists Discovery
Using the Planethunters.org website, a Yale-led international team of astronomers identified and confirmed discovery of the phenomenon, called a circumbinary planet in a four-star system. Only six planets are known to orbit two stars but none of these are orbited by a distant binary.
Why We Cling To Superstitions, Even If Our Rational Side Knows They're Not True
How Taste Buds Work
What is generally categorized as “taste” is basically a bundle of different sensations: it is not only the qualities of taste perceived by the tongue, but also the smell, texture and temperature of a meal that are important.
New Species of Leafhopper Discovered
A new species of the leafhopper genus Flexamia from the New Jersey Pine Barrens, located just east of the megalopolis that extends from New York City to Washington, DC.
Horses Are Getting Faster
A new analysis of race times from 1850 to 2012 shows that racehorses, on average, are getting faster every year.
Some Risks May Be Good For Kids
Children are living more constrained lives than previous generations, and fewer are left alone to wander and get up to shenanigans as their parents did, said Tim Gill, a childhood researcher and the author of "No Fear: Growing Up in A Risk Averse Society" (Calouste Gulbenkian Foundation, 2007).
17,000 Species Face Extinction
Sea Lion now endangered. View the complete list at the link below.
Ice Age Mummified Puppy Found
The 3-month-old female was found in the permafrost, which kept the body in a remarkable state of preservation, with little decomposition. Parts of the puppy’s heart, liver, lungs, stomach, and intestines survived, as did its skin and fur.
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.
The Quiet Life Of The Milky Way
TheMilky Way has had a sheltered life. A search for the signs of a violent galactic upbringing has come up empty, and the finding is helping astronomers understand our galaxy's history. It could also aid the search for dark matter.
DNA Code For The Woolly Mammoth
Scientists a step closer to "bringing back" mammoths...
How DNA Is Like A Yo-Yo
A new study shows that the coiled DNA acts much like the string on a yo-yo. And that’s good, because by being rolled up, each cell can store a lot of instructions.
Journey To Mars
Like cannonballs slamming into stained glass, high-energy particles can shatter the delicate tendrils that connect nerve cells, a study on mice finds. This neural destruction left mice with memory and learning problems, a finding that has implications for intrepid space explorers.
A new study explains the bond between humans and dogs,
