Human Tissue Successfully Grafted Into Monkeys With Damaged Retinas
by Justine Alford
There could be hope on the horizon for an untreatable genetic disease: Scientists have successfully grown eye tissue in the lab and transplanted it into monkeys with models of a human degenerative disease that affects the retina. Not only did the graft survive, but it also showed signs of integration with the recipient’s eye cells, forming connections across which information could potentially flow. While this certainly doesn’t mean a cure is close, it demonstrates that the strategy could at least be feasible in humans, and lays the foundations for further studies.

Hot Tea Freezing In Mid-Air Captured In Stunning Photograph
by Robin Andrews
It’s pretty cold in the north of Canada at any time of year, but in the winter, temperatures plummet to incredible lows. Ontario-based photographer Michael Davies and his friend Markus stood at the top of a mountain and demonstrated this by throwing leftover tea into the air, dramatically photographing it instantaneously freezing.

Researchers Have Pinpointed The Most Lightning-Struck Spot On Earth
by Ben Taub
They say lightning never strikes twice, although whoever "they" are might want to have a rethink. New research presented at the American Geophysical Union Fall Meeting suggests that one spot in a Venezuelan lake receives a bolt of lightning on 297 days out of 365 each year.
Solar Farm Rejected Over Fears It Could Drain The Sun, Cause Cancer
by Justine Alford
The Paris climate change agreement is a triumph for the planet, but the widespread ignorance of this subject demonstrates a failure of science communication. And this ignorance is more than just a laughing matter: it could represent an obstacle to reaching certain energy goals. For instance, a town in the U.S. has just blocked construction of a solar farm, in part due to fears it would drain the Sun’s energy, Roanoke-Chowan News-Herald reports.

Underwater Hotel Receives Patent Approval
by Ben Taub
Tourists looking for a room with an ocean view will be thrilled to hear about the development of a new submarine hotel, which will lie 8.5 meters (28 feet) beneath the waves. Having recently received patent and trademark approval, the Planet Ocean Underwater Hotel is all set to be constructed in Key West, Florida, after which it will be shipped out on a barge to an as yet undecided location.
New Hybrid Fuel Cell Made From E. Coli, Gold, And Titanium
by Robin Andrews
Escherichia coli (E. coli) is not something anyone wants to come into contact with; after all, this bacteria is responsible for fairly potent, sometimes dangerous, food poisoning. A team of researchers from Singapore have found a way to engineer E. coli to perform a very different role: It's now a catalyst for a new hybrid fuel cell that splits hydrogen from water with remarkable efficiency. Its curious workings are detailed in a study published in the journal NPJ Biofilms and Microbiomes.
New "Skyscraper" Chip May Be 1,000 Times More Efficient Than Silicon
by Ben Taub
Silicon Valley may soon have to change its name, as the days of using silicon to create computer chips could be numbered thanks to the work of a Stanford University-led team of scientists. By using nanomaterials – meaning materials measuring less than 100 nanometers in at least one dimension – the researchers have managed to create a new type of chip that they say can operate up to 1,000 times more efficiently than silicon chips.

Google Files Patent For Needle-Free Blood-Drawing Smartwatch
y Alfredo Carpineti
We knew that the competition between tech companies was fierce, but who knew that Google was actually out for blood? The Mountain View, California company has recently filed a patent for a smartwatch that can extract blood from a person without using a needle.

Our Black Hole's Magnetic Field Has Been Studied For The First Time
by Alfredo Carpineti
Astronomers, for the first time, have observed the expected magnetic field around the event horizon of Sagittarius A*, the supermassive black hole at the center of the Milky Way. The results are published in the journal Science.

Scientists Discover New Form Of Carbon That Can Make Diamonds At Room Temperature
by Alfredo Carpineti
Scientists from North Carolina State University have discovered a new form of solid carbon, called Q-carbon, and it has some unusual properties: Q-carbon is ferromagnetic, harder than diamond, and glows when exposed to energy. These properties make it different fromgraphite and diamond

Exiled Exoplanet Might Be A Super-Saturn
by Alfredo Carpineti
One of the most beautiful things in science is that no matter how much we know about the universe we still get surprises which send us back to the drawing board. Exoplanet HD 106906b is one of those surprises. It’s a huge planet that shouldn’t exist, but not only does it, astronomers think it may also have a ring around itself like a super-Saturn.
Should We Be Editing Human DNA?
by Robin Andrews
Ever since the structure of DNA was discovered in 1953, our constantly evolving understanding of it, and our application of this knowledge, has represented one of thegreatest endeavors in human history. It’s a science not without controversy, however: The modification of human DNA is a particularly sensitive subject. In order to reach a global consensus on the ethics of editing human DNA, a three-day-long summit in Washington DC, from December 1-3, is taking place to discuss this contentious subject.
Scientists Map Four Billion Years Of Ribosomal Evolution
by Ben Taub
Funded by NASA’s Astrobiology Institute, a team of researchers from the Georgia Institute of Technology has retraced the development of the ribosome back almost four billion years, unlocking the chronology of its evolution from its primordial form to its present structure. The ribosome provides a site for protein synthesis in all living cells, and is therefore crucial for the existence of life. By unravelling the secrets of its formation, the new research has shed light on the pre-conditions for life, providing a window into a time that predates biology.

New Computer Costs Just $5 And It's Smaller Than A Credit Card
by Jonathan O'Callaghan
A new version of the groundbreaking Raspberry Pi computer has just gone on sale, called the Pi Zero, and you certainly won’t have to break the bank to get one – it costs just $5 (£4).
The awesome single-board computer, which is smaller than a credit card, is significantly cheaper than the already affordable original Raspberry Pi, which is priced at $25 (£16).

New Distance Record Set In Entangling Electrons
by Alfredo Carpineti
A new day, a new quantum computing record broken. In new research, physicists from Stanford were able to entangle two electrons that were located 2 kilometers (1.2 miles) from each other.
Usually, entangled particles are created together and then separated, but in this case, the electrons were entangled using two messenger photons that carried the properties of each electron in a phenomenon called quantum correlation. The two photons are then sent down an optical fiber and are forced to interact in the middle. The combination of quantum correlation and photon interaction made the electrons entangled.

New Li-Fi Internet Is 100 Times Faster Than Wi-Fi
by Ben Taub
When Thomas Edison invented the electric lightbulb, he could hardly have imagined that one day his creation would be used not only to illuminate homes around the world, but also to transmit data that would enable people to download information from satellites in space to small hand-held devices. However, with the introduction of Li-Fi, household lighting could soon double as a form of data transmission that’s up to 100 times faster than Wi-Fi.
First Macroscopic Quantum Entanglement At Room Temperature Achieved
by Alfredo Carpineti
November has been a great month for quantum entanglement fans. Not only was entanglement proven to be a fact of nature, but the first quantum computer code was written on an entangled system as well. Now, scientists from the University of Chicago were able to obtain a quantum entanglement state at room temperature in a macroscopic (relatively large) object. Macroscopic objects are expected to obey exclusively classical physics, so this experiment is a big deal.

fly anywhere at anytime with icon's A5 personal aircraft
mission is to bring the freedom and adventure of flying to all who have dreamed of flight. the FAA’s dramatic 2004 regulation changes that created the light sport aircraft category have redefined the possibilities for aviation and allowed the company to create the ’A5’ consumer aircraft. it uses the most cutting edge materials and techniques to achieve its performance. the plane takes one person just two minutes to unfold the ‘A5’s’ wings and be ready of the open skies. to transport the aircraft, the icon ‘amphibious trailer’ loads like car and unloads like a boat.
