Germany had so much renewable energy last week that customers were briefly being paid to consume electricity, it has been reported.

As spotted by Quartz, who cite data from German think tank Agora Energiewende, fair weather and high winds on Sunday 8 May saw wind, solar and hydroelectric power plants producing 54.6GW of power, roughly 80 per cent of the 68.4GW of power being consumed across the country at that time.

As a result, the price of power plummeted, and went negative from 7AM to 5PM, bottoming out at -€130 per MWh at 1PM. Energy providers were essentially being paid by producers to take the electricity off their hands.

In Brief Scientists from the Imperial College have discovered that light could possibly exist in a previously unknown form, as a mix with a single electron. This interaction creates light that has the properties of both particles.

For something that seems so integral to our lives, we are still discovering many things about light. Its most fundamental properties still astound us, and its interactions with other particles are full of surprises. Case in point, scientists from the Imperial College in London seem to have just discovered a new form of light, one made by combining light with a single electron particle.

This new form of light carries properties of both particles.

In Brief DARPA has created self-steering bullets which use a real-time optical guidance system to hit both moving and accelerating targets with high accuracy.

You may have seen the movie Wanted. Sure, the movie was almost unrecognizable from the Mark Millar comic book series it was very loosely based on. But that didn’t stop anyone from pretending to be a bullet-curving, badass, supervillain-with-a-heart sniper like Angelina Jolie after seeing it.

But the Defense Advanced Research Projects Agency’s (DARPA) new self-steering bullet is about to change the pretend part into reality.

“By comparing clonal and sexual daughters from the same mothers, we found sexually produced offspring get less sick,” Auld said.


PARIS – From an evolutionary perspective, sexual reproduction could be seen as a nonstarter. Compared to cloning, which also exists in nature, it is a major waste of time and energy.

Think of the ungainly, preening peacock — an easy snack for tigers and wild dogs — strutting his stuff to impress the ladies.

Even without predators, sex and its attendant rituals can be dangerous, such as when stags butt heads or male lions fight for mating rights.

Last year – although a rather grim one by other measures – was a splendid one for research. From gravitational waves to cooing dinosaurs, we’ve uncovered a lot about the world around us, but as a remarkable new study has revealed, there’s a lot within us we’ve yet to discover too.

Writing in The Lancet Gastroenterology & Hepatology, scientists have officially announced the discovery of a new organ inside the human body. That’s right, there’s a brand new organ hiding in our abdomen and it’s only just been classified.

Known as the mesentery (meaning “in the middle of the intestines”), it can be found in our digestive systems. Leonardo da Vinci actually gave one of the first descriptions of it back in the day, but until around 2012 it was thought to be a series of separate structures keeping the intestines attached to the abdominal wall, like a series of support girders.

The answer may be counter-intuitive: Not only can Bitcoin be widely adopted under a supply cap, its trust and integrity are a direct result of a provably limited supply. As a result, it will flourish because it is capped.

Everyone Can Own and Trade a Limited Commodity, IF…

…if it is both measurable and divisible. Bitcoin has a capped supply just as gold has a capped supply. Although both assets will be mined for some time into the future, there is only so much that will ever be uncovered. Thereafter, the total pie cannot grow.

But the transaction units will continue to grow as needed, because the pie is divisible into very, very tiny units:

There will eventually be 21 million BTC and each coin is divisible into 108 units. This yields (21 million * 100 million), or 21 trillion exchangeable units. And, it can be divided further by consensus.

As Bitcoin is adopted—whether as a simple payment instrument, an investment asset or even as national currencies around the world—each unit of the limited supply simply rises in value. If thought of as a currency, with a value established by supply & demand, it leads to a deflationary economy.

But, Isn’t Deflation Bad for the Economy?

It’s common to associate deflation with economic ills. One need only glance back at the the last century to conclude that deflation coincides with wars, joblessness, recession and a crippling concentration of wealth. Perhaps, just as bad, the tools used to pull a nation out of deflation often force governments to cherry pick beneficiaries of stimulus spending.

But it is important to note that deflation plays no role in causing these things. On the contrary, it is an effect rather than a cause… In fact, when a supply cap is introduced as a designed control input for monetary policy, all sorts of good things follow. I address these in various answers at Quora. Dig in:

After 15 years of development, an Israeli tech firm is optimistic it will finally get its 1,500 kilogramme (1.5 tonne) passenger carrying drone off the ground and into the market by 2020.

The Cormorant, billed as a flying car, is capable of transporting 500 kilogrammes (around half a tonne) of weight and travelling at 185 kilometres per hour. It completed its first automated solo flight over terrain in November. Its total price is estimated at $14 million.

Developers Urban Aeronautics believe the dark green drone, which uses internal rotors rather than helicopter propellers, could evacuate people from hostile environments and/or allow military forces safe access.
