The giant honeycomb-like setup of 149 spotlights — officially known as "Synlight" — in Juelich, about 30 kilometers (19 miles) west of Cologne, uses xenon short-arc lamps normally found in cinemas to simulate natural sunlight that's often in short supply in Germany at this time of year.
By focusing the entire array on a single 20-by-20 centimeter (8x8 inch) spot, scientists from the German Aerospace Center, or DLR, will be able to produce the equivalent of 10,000 times the amount of solar radiation that would normally shine on the same surface.
Creating such furnace-like conditions — with temperatures of up to 3,000 degrees Celsius (5,432 Fahrenheit) — is key to testing novel ways of making hydrogen, according to Bernhard Hoffschmidt, the director of DLR's Institute for Solar Research.
Many consider hydrogen to be the fuel of the future because it produces no carbon emissions when burned, meaning it doesn't add to global warming.
The Endless Runway is a radical and novel airport concept, which applies a circular runway. The concept of the Endless Runway can generate a breakthrough in sustainable airport capacity by avoiding the physical constraints of conventional runways through shifting the lift-off and touchdown points of individual aircraft.
The main feature of the circular runway is that it will become possible to let an aircraft operate always at landing and take-off with headwind. Whatever its strength and direction, the Endless Runway becomes independent of the wind. When allowing limited crosswind, airspace users can shorten the global trajectory of the flights through optimized departure and arrival routes.
The circle of the runway, whose diameter is set to 3 kilometers, is large enough to provide sufficient room for infrastructure preferably inside the circle, even for a hub airport. This makes the airport compact, while allowing current-day aircraft to use the circle without significant structural modifications.
Alibaba, Tencent, Xiaomi, BBK Electronics, Huawei, and Dalian Wanda are changing the products and services you use, whether you know it or not.
In the past year, no industry has attracted more Chinese interest (and raised American alarm) than entertainment, which Chinese companies are pursuing with a mix of prodigious capital and strategic deal-making. Tencent and real estate giant Dalian Wanda have joined Alibaba in committing billions of dollars to help produce the kind of technologically ambitious and expensive film and TV projects that appeal to global audiences. Given the idiosyncrasies of the Chinese market (traditional Western advertising campaigns tend to fall flat there, and the country places strict quotas on non-Chinese films), American studios need to partner with these companies to access this key element of the global box office. "If you’re going to spend over $100 million on a movie and ignore the Chinese market," says Max Michael, head of Asian business development for the United Talent Agency, "you’re not doing your job right."
“What do we lose when a written language dies? And what happens when some daft Englishman living in Vermont decides to buck the global trend and write slowly, using tools a thousand years old?
I launched the Endangered Alphabets Project, and I started documenting these losses in a medium more permanent than paper or the fleeting pixel. Learning about woodwork as I went, I carved Balinese and Javanese from Indonesia; Tifinagh from North Africa and Bassa Vah from West Africa; Lanna from Thailand and the traditional Mongolian script called bichig. First by emailing scholars and later through Facebook, I gradually developed a network of contacts. To my astonishment, I started getting emails from the other side of the planet with tiny miracles of exotic text to enlarge, transfer with carbon paper, and gouge into maple, cherry, walnut, and sapele.”
For thousands of years, the coconut palm has entwined itself in history, from tropical coasts to typical shelves in global groceries. Called the “tree of life” by the many cultures that have depended upon it through time, it provides sustenance, succor and shelter. While it now grows on every subtropical coastline around the world, genetic testing underwritten by the National Geographic Society in 2011 showed the coconut originated in India and Southeast Asia. From its original home, the nut—which can float—made its way independently, traversing both hemispheres.
This was not a scene from a new X-Men movie, but an event organised by two Cambridge institutions: the Centre for the Study of Existential Risk (CSER, commonly referred to as "caesar") and the Leverhulme Centre for the Future of Intelligence. For them, it was a fairly ordinary evening, in this case following a lecture by Katyal. The apocalyptic talk is standard: both bodies are among a small group of organisations in the UK and US which employ highly educated academics, scientists, lawyers and philosophers to study existential risk.
“True to this vision, the Web Foundation has chosen to focus our 2017 – 2022 strategy on delivering ‘digital equality’ — using the open web to build a more equal world. Why? Because despite the wave of creativity, innovation and collaboration unleashed by the web, the reality is that today, the web is not for everyone. In fact, the digital revolution is creating new patterns of privilege and discrimination. It is causing job losses and wage polarisation as well as productivity gains; it risks taking away our privacy and autonomy even as it gives ordinary citizens new powers; it is isolating us in filter bubbles as well as connecting us across borders; and it is amplifying voices of fear and hate just as much as voices for tolerance and rationality.
We must act now to close the divide between digital haves and have-nots or we risk losing the web’s potential to serve humanity forever. To do this, we must work harder to ensure that everyone has the access, skills, and freedoms to appropriate and control new technologies for their own benefit. We must also make sure that control of the web is not held by a few governments or companies.”
In Blacksburg, a satellite Silicon Valley is emerging, with startups Card Isle, a Redbox for greeting cards, and Moveline, a moving-company-price-comparing service, among dozens of others all calling it home. Overlooking the grassy stains and sloping foothills just minutes from the Hokies football stadium, the cloud-storage behemoth Rackspace (see video) has created a campus replete with rock-climbing walls and, yes, Ping-Pong tables, just a few miles away from less hospitable cyber climes.
Over in Roanoke, a fragile compromise struck between business and government has laid track for industry-leading fiber internet. The effort is seeking to salve a city where a local councilman recently had trouble selling his home because speeds weren’t fast enough for work-from-home buyers, he told OZY, and where a neighboring county with poor North Shore parents have to drive their children back to school after hours to finish their homework, according to local officials. Following concerns from local businesses that led to action, Roanoke has seen the first fruits of its internet investment: Local software firm Meridium, which benefits from the new fiber, was acquired for $500 million by General Electric.
When it comes to the state of the tax code, there’s a surprising amount of consensus in Washington: liberals, conservatives and every President from Bill Clinton to Donald Trump agree that the corporate tax is broken, ineffective and needs to be fixed.
The problem, in a nutshell, is that the 35% corporate tax rate is among the highest in the developed world. But because of loopholes, it produces less federal revenue, as a percentage of GDP, than most other countries’. The current system also creates an incentive for companies to perform feats of legal acrobatics, like relocating corporate headquarters and shuffling intellectual property to far-flung foreign locales, to shield their balance sheets from the IRS.
That’s where the BAT comes in. In theory, this little tax will fix those big problems. Instead of taxing corporate profits, the BAT taxes corporate cash flow. That means it doesn’t matter where a company’s headquarters are located or where its intellectual property is housed. All that matters is where it sells its products. If it sells its products in America, it pays 20% on what it makes. If it sells its products abroad, it pays no U.S. corporate tax at all. (Foreign taxes would still apply.)
Every member of staff -- from the flight's captains to the cabin crew, check-in and ground handling staff -- were women. Even the engineers, who certified the aircraft, and air traffic controllers, who cleared its departure and arrival, were women, the company said.
An Air India spokesman told CNN that the airline has applied for a Guinness World Record to mark the occasion, part of a series of all-women flights scheduled to mark International Women's Day on March 8.
