What you're looking at above is a 773g Chinga meteorite that's been cut and polished on two sides. The top portion retains its natural light brown crust to create a dramatic contrast. This particular specimen is an iron meteorite and its total chemical composition is: 82.8% iron, 16.6% nickel, and the rest mostly cobalt and phosphorus.

Julian Melchiorri has created the first biological leaf that has the chloroplast from real plants suspended inside. He basically used a silk fiber to suspend the chloroplast in place so that it still functions like a plant, but with a super-structure to make it extra durable. In other words, these synthetic leaves can create endless oxygen using light and water. Continue reading for an up-close image of the man-made leaf.

The Drake equation is basically a probabilistic argument used to estimate the number of active, communicative extraterrestrial civilizations in the Milky Way galaxy. In November 2013, astronomers reported, based on Kepler space mission data, that there could be as many as 40 billion Earth-sized planets orbiting in the habitable zones of sun-like stars and red dwarf stars within the Milky Way Galaxy. 11 billion of these estimated planets may be orbiting sun-like stars. Since there are about 100 billion stars in the galaxy, this implies fp*ne is roughly 0.4. The nearest planet in the habitable zone may be as little as 12 light-years away, according to the scientists. Continue reading for more.

This past Thursday morning, a river in eastern China turned a shade of crimson red, which residents say reminds them of a blood-like color. China Radio International reports, "Local residents say the river was running normally at 4am, but it started to redden at around 6am, and in no time turned as crimson as blood. The villagers pointed out that there wasn't a chemical plant along the upper stream." Click here to view the first image in this week's demotivational poster gallery.

We have seen the future of sports cars, and they just might be salt water-powered. The QUANT e-Sportlimousine utilizes a nanoFLOWcell system, which is comprised of a three-tank system that stores two types of liquid electrolytes - one positively charged, the other negatively - to generate 912-horsepower.

Sam Van Aken created a tree unlike in any other because it's designed to bear 40 different kinds of fruit. Science Alert says, "Van Aken used a technique called chip grafting to add more varieties on as separate branches. This technique involves taking a sliver off a fruit tree that includes the bud, and inserting that into an incision in the working tree. It's then taped into place, and left to sit and heal over winter. If all goes well, the branch will be pruned back to encourage it to grow as a normal branch on the working tree." Continue reading for a video of him explaining this at TED Talks.

On a clear, dark night, our eyes can see thousands of stars in the sky in places without light pollution. They always seem to twinkle, or change their brightness, all the time, but in reality it's the movement of air (sometimes called turbulence) in the atmosphere of Earth causes the starlight to get slightly bent as it travels from the distant star through the atmosphere down to us on the ground, producing a twinkling effect. You'll notice that stars closer to the horizon will appear to twinkle more than other stars. This is because there is a lot more atmosphere between you and a star near the horizon than between you and a star higher in the sky. Continue reading for more.

Called Impervious, this innovative super-hydrophobic nanospray contains molecules 1,000 times smaller than a human hair and can make just about anything water-resistant in minutes. You can either choose to spray it onto the screen - the thin layer of protection it provides also prevents the screen from being scratched - of any device, or the entire gadget. Once applied, the company says that gadgets can be submerged in 3-feet of water for 30 minutes. Continue reading for the demonstration video and more information.

Millions of mayflies emerged from the Mississippi River near and around La Crosse, Wisconsin on July 20th, producing a swarm so large that it appeared on radar. According to news station KARE 11, "As the flies dispersed moving north-northeast, they also gained altitude with some of the echo being detected as far north as Black River Falls and as high as 2500 feet above ground."
