China has put $3.3 billion into making new highly compact nuclear reactors which would also use for nuclear powered drones.
The potential impact of nuclear-powered drones can be seen by comparing them with existing aircraft such as the MQ-9 Reaper, which is used extensively in Afghanistan and Pakistan in operations against insurgents. The Reaper presently carries nearly two tonnes of fuel in addition a similar weight of munitions and other equipment and can stay airborne for around 42 hours, or just 14 hours when fully loaded with munitions.
Breakthrough research from The University of Texas at Arlington and The University of Vermont could lead to a dramatic reduction in the cost and energy consumption of high-speed internet connections.
Nonlinear-optical effects, such as intensity-dependent refractive index, can be used to process data thousands of times faster than what can be achieved electronically. Such processing has, until now, worked only for one optical beam at a time because the nonlinear-optical effects also cause unwanted inter-beam interaction, or crosstalk, when multiple light beams are present.
An article published in the prestigious Nature Communications journal, by the research group of Michael Vasilyev, an electrical engineering professor at UTA, in collaboration with Taras I. Lakoba, a mathematics professor at UVM, detailed an experimental demonstration of an optical medium in which multiple beams of light can autocorrect their own shapes without affecting one another.
Freshly discovered malware called Triton can compromise safety systems that control many kinds of industrial processes.
For years, security experts have been warning that hackers can disable systems that control critical infrastructure we all rely on, such as dams and power plants. Now researchers at Mandiant, which is part of the security firm FireEye, have revealed that a new form of malware, dubbed Triton, closed down the operations of a business in the Middle East belonging to Schneider Electric, a French company. The researchers say that they haven’t attributed the hack to a particular attacker, but they do say it bore hallmarks of threats from a nation-state.
Triton appears to have targeted a so-called safety instrumented system, or SIS, which monitors the operation of a physical process using sensors and acoustics. By taking control of it, hackers can destroy or damage the process the SIS is monitoring by tricking it into thinking everything’s normal, when in fact the process is operating at unsafe levels.
The humble house plant could soon start earning its keep by lighting up a room, if new research from MIT pans out. Engineers have hacked watercress plants to make them glow for a few hours at a time, and while it’s currently only about as bright as those old stars you might have stuck to your ceiling as a kid, the long-term plan is to develop plants that you could read by to reduce the need for electric lighting.
The idea of a glowing plant is not particularly new. They’ve been promised by Kickstarter campaigns for years, including the likes of Bioglow and Glowing Plants, but those startups have since gone bust. Although we’re not going to pretend that this new project is immune from meeting the same fate, having the backing of MIT scientists gives us a little more hope that the glowing plants might eventually bear fruit.
The work comes from the same “plant nanobionics” team that recently designed explosive-detecting spinach and leaf sensors that can alert farmers at the first sign of thirsty crops. In this case, the researchers wanted to tackle lighting, which accounts for about 20 percent of energy consumption worldwide.
Scientists have developed new 3D-printed plastic objects that can hook up to Wi-Fi without the aid of any electronics or batteries, meaning household devices could get a lot smarter in the future without the need for any circuitry.
If that’s not blowing your mind just yet, think about this: the tech could be used to make a laundry bottle that orders a refill online as soon as it runs out, or a simple volume slider that connects to your speakers without any cabling or even a power source.
So how is this possible? To achieve this, a team from the University of Washington built a system comprising a plastic switch, spring, gear, and antenna, which when activated with a press or other movement can absorb or reflect passing Wi-Fi signals in order to communicate.
A research team led by faculty at Binghamton University, State University of New York has developed an entirely textile-based, bacteria-powered bio-battery that could one day be integrated into wearable electronics.
The team, led by Binghamton University Electrical and Computer Science Assistant Professor Seokheun Choi, created an entirely textile-based biobattery that can produce maximum power similar to that produced by his previous paper-based microbial fuel cells.
Additionally, these textile-based biobatteries exhibit stable electricity-generating capability when tested under repeated stretching and twisting cycles.
The Tesla big battery – the world’s biggest lithium-ion battery storage installation to date – was officially switched on in South Australia on Friday, a day after it had already demonstrated its value by injecting energy into the grid during the previous day’s afternoon peak.
South Australia premier Jay Weatherill, whose government has provided the subsidy for the battery to be built on the grid with the largest penetration of wind and solar anywhere in the world, described it as a “landmark moment”.
“This means that, for the first time, clean and affordable wind energy can be dispatched to the grid 24 hours a day, 7 days a week, whether the wind is blowing or not, improving system reliability,” Weatherill said.
Over the past two decades start-ups have changed the world. Multi-billion dollar companies like Google, Facebook, and Uber have shown the transformative power of entrepreneurship.
Today, innovators dream of their idea becoming the next big thing. But the odds are stacked against them. In America alone, 80% of startups will fail. In startup hubs around the world young entrepreneurs are desperate to prove they have what it takes to succeed. But what does it really take to survive?
HoloMe is one of half a million companies to start up in Britain every year. The nations capital is a leading hub of innovation, inspiration, and creative energy. In London, and in cities world wide it’s the age of the entrepreneur.
Startups are championed by governments who see them as key to building a dynamic economy, but the competition is cut-throat. To succeed, you’ve got to really believe in your product.
Way back in 1811 and 1812, a series of over 1,000 earthquakes rocked the Mississippi River between St. Louis and Memphis. One was so powerful that it caused the river to run backwards for a few hours. The infamous New Madrid earthquakes of 1811–1812 rang church bells in Boston, which is 1,200 miles from St. Louis. Today, scientists say that the 150-mile-long New Madrid Seismic Zone has a terrifying 40% chance to blast in the next few decades, impacting 7 states – Illinois, Indiana, Missouri, Arkansas, Kentucky, Tennessee and Mississippi – with 715,000 buildings damaged and 2.6m people left without power.
Unlike California, which has been super-prepared since the last major earthquake hit hard enough to delay the World Series, the New Madrid fault area has been sitting blissfully by. In case the “40 percent” statistic didn’t bother you, this should: The New Madrid fault has an impact zone ten times as big as its more famous San Andreas cousin.
As described by USGS: “In 1811, the extent of the area that experienced damaging earth motion, which produced Modified Mercalli Intensity greater than or equal to VII, is estimated to be 600,000 square kilometers. However, shaking strong enough to alarm the general population (intensity greater than or equal to V) occurred over an area of 2.5 million square kilometers.”
