Richard Branson’s Virgin Orbit Fails on First Rocket Launch Attempt
(LOS ANGELES) — Richard Branson’s Virgin Orbit failed Monday on its first attempt to launch a test satellite into space aboard a rocket carried aloft by a Boeing 747 and released over the Pacific Ocean off the coast of Southern California.
The inaugural launch had appeared to be going well until moments after the rocket was dropped from beneath the left wing of the jumbo jet dubbed...

Virgin Orbit’s LauncherOne rocket misses going to space during its first air launch
A new breed of launch vehicle had a shaky first outing today when Virgin Orbit released its LauncherOne rocket from a modified Boeing 747 jumbo jet flying over the Pacific Ocean for its first blastoff. "We've confirmed a clean release from the aircraft," Virgin Orbit reported in a tweet. "However, the mission terminated shortly into the flight." In a follow-up Twitter...
Scientists see through glass frogs' translucent camouflage
Glass frogs are well known for their see-through skin but, until now, the reason for this curious feature has received no experimental attention.
Researchers discover new sex hormone
When University of Ottawa biologists Kim Mitchell and Vance Trudeau began studying the effects of gene mutations in zebrafish, they uncovered new functions that regulate how males and females interact while mating. We sat down with senior author Professor Trudeau, Research Chair in Neuroendocrinology at the Faculty of Science, to learn more.
Solving the space junk problem
Space is getting crowded. Aging satellites and space debris crowd low-Earth orbit, and launching new satellites adds to the collision risk. The most effective way to solve the space junk problem, according to a new study, is not to capture debris or deorbit old satellites: it's an international agreement to charge operators "orbital-use fees" for every satellite put into orbit.
Why glass frogs have see-through skin becomes clear in study
While colour of body changes little, legs are more translucent to help amphibians to blend inThe mystery of why glass frogs have see-through skin has been solved, scientists say: the unusual feature is a type of camouflage.Glass frogs are found in tropical Central and South America, and get their name from their skin.

Galactic crash may have triggered solar system formation
The formation of the Sun, the Solar System and the subsequent emergence of life on Earth may be a consequence of a collision between our galaxy, the Milky Way, and a smaller galaxy called Sagittarius, discovered in the 1990s to be orbiting our galactic home.
Eating local and plant-based diets: how to feed cities sustainably
How do you feed a city? It is one of the great questions of our time. After all, for a species that ultimately depends on plants to feed ourselves, we do tend to cram ourselves into places that are rather unfriendly towards them. Our cities are built around cars, offices and perhaps the odd park—not fields of crops.
