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.
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.

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.

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.
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.

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.

According to the Kardashev scale, a Type II civilization is a society that has managed to harness (and control) the energy of a star. Here's what that means.
How Did Life Evolve On Earth?
The answer to this question would not only fill one of the largest gaps in scientists' understanding of nature, but also would have important implications for the likelihood of finding life elsewhere in the universe.
Jupiter's Great Red Spot
Observations show that Jupiter's upper atmosphere — above the Great Red Spot — is hundreds of degrees hotter than anywhere else on the planet.
Largest Dinosaur Print Found
A footprint measuring over a meter wide that was made by a meat-eating predator some 80 million years ago has been discovered in Bolivia, one of the largest of its kind ever found.

Planet Number Nine?
Work since 2014 has defined Planet Nine’s potential properties. Evaluation of "neighboring" small body orbits indicate that it is many times more immense than Earth, possibly around 15 times the size, and at the nearest point of its extremely extended, oblong orbit it is a minimum of 200 times more distant from the Sun than Earth, or more than 5 times the distance from the Sun to Pluto.

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.

We Think Better Standing
"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.
