Hong Kong (CNN)A US Navy warship has successfully tested a new high-energy laser weapon that can destroy aircraft mid-flight, the Navy’s Pacific Fleet said in a statement Friday.
Images and videos provided by the Navy show the amphibious transport dock ship USS Portland executing “the first system-level implementation of a high-energy class solid-state laser” to disable an aerial drone aircraft, the statement said.
The images show the laser emanating from the deck of the warship. Short video clips show what appears to be the drone burning.
This is the new Aquabreather Hydroid. Rebreather? No. Scuba diving? Yeah, but not the way you’ve ever seen it!
The Hydroid aquabreather was unveiled at the 2019 DEMA exhibition. This was without a doubt the one scuba diving product which generated the most buzz.
Part HALO, part NASA, part Darth Vader, the Hydroid Aquabreather uses proprietary canisters of a chemical mixture that gives off oxygen once popped. This is then cycled by your mask, and you will be able to dive to a depth of 42 metres. (138 feet) and stay underwater for 1 hour.
The EmbraerX Pulse features a stylish glassed-over cabin that slots into both electric car and eVTOL bodies for seamless multi-mode end-to-end transport
Here’s one we missed from several months ago: Brazilian eVTOL innovator EmbraerX put forth a fun video showing how a multi-mode 3D transport system might work, with an eVTOL air taxi carrying a detachable glassed-over cabin that it delivers straight onto a self-driving car chassis.
The coming new breed of eVTOL air taxis are nearly all, at this stage, designed to work as part of a multi-mode transport scheme. The flying taxis themselves will travel from skyport to skyport, meaning you’ll need other means to get yourself to the takeoff point and something else again at the other end for the last mile. It’s simply not practical to expect eVTOLs to drop you off right at your destination.
Companies like Uber are salivating at the thought of being able to offer the whole service as a single sale, co-ordinating a car at each end to minimize travel time, but that starts looking like a bit of an annoyance when you consider the hope is that people will use these things for the daily commute. Four taxis and two eVTOLs every day is a pain.
And so we get this concept from Embraer’s flying taxi division EmbraerX. The Pulse system has a single, shared, glassed-over luxury cabin that can click into an eVTOL airframe or clip onto a skateboard electric car chassis, something like what REE makes.
Intense summer sun can spike temperatures of solar panels, causing their electrical production to plummet.
Like humans, solar panels don’t work well when overheated. Now, researchers have found a way to make them “sweat”—allowing them to cool themselves and increase their power output.
It’s “a simple, elegant, and effective [way] to retrofit existing solar cell panels for an instant efficiency boost,” says Liangbing Hu, a materials scientist at the University of Maryland, College Park.
Today, more than 600 gigawatts of solar power capacity exists worldwide, providing 3% of global electricity demand. That capacity is expected to increase fivefold over the next decade. Most use silicon to convert sunlight to electricity. But typical silicon cells convert only 20% of the Sun’s energy that hits them into current. Much of the rest turns into heat, which can warm the panels by as much as 40°C. And with every degree of temperature above 25°C, the efficiency of the panel drops. In a field where engineers struggle for every 0.1% boost in power conversion efficiency, even a 1% gain would be an economic boon, says Jun Zhou, a materials scientist at Huazhong University of Science and Technology.
Decades ago, researchers showed that cooling solar panels with water can provide that benefit. Today, some companies even sell water-cooled systems. But those setups require abundant available water and storage tanks, pipes, and pumps. That’s of little use in arid regions and in developing countries with little infrastructure.
Engineers at the Georgia Institute of Technology have designed the first robot capable of not only playing music, but creating music—and its name is Shimon.
The musical robot was trained on a vast data set of everything from progressive rock to jazz to rap. Shimon takes this knowledge of past music and uses algorithms to come up with unique robot music of his own.
From the people who brought you the iPhone: a whole new theatrical experience.
It’s no big secret that the movie theater industry is facing an existential crisis, with serious challenges coming from streaming platforms developed by technology giants like Apple, Netflix, and Amazon, and now a pandemic that’s forced cinemas to shutter around the globe. Weighing the future of movie theaters has become a favorite guessing game for media analysts. Last Friday, the New York Times asked: “Movie Theaters Are on the Brink. Can Wine and Cheese Save Them?”
Maybe not. But there’s reason to believe that the very tech companies threatening the industry could breathe new life into movie theaters.
Last week, rumors circulated that Amazon is interested in acquiring AMC, the largest theater chain in the United States. The news caused a sharp spike in AMC’s stock price. The company has had a rough year: The chain lost money in 2019, despite multiple billion-dollar tentpole releases such as Avengers: Endgame, The Lion King, and Frozen 2. And that was before the coronavirus pandemic shut down theaters worldwide. Now, some analysts have speculated that the company might file for bankruptcy. While the theater chain denied the speculation, it raised $500 million in additional debt to weather the current crisis.
Covid-19 is proving to be the impetus the legal industry needed to embrace remote technologies, Merchant & Gould attorneys write. They look at how law firms are adjusting to new technologies now and how courts may adopt new technologies going forward.
In law firms, one might guess the graduation year of attorneys based only on the technologies employed in their practices.
Lawyers graduating in the last decade may have never even seen a dictaphone in person or have experienced paper cuts from thumbing through thousands of paper documents to prepare them for production in litigation. Only recently did a small number of litigators begin using tablets instead of paper documents in depositions. Nearly all litigators firmly believed it was not possible to effectively conduct a deposition or hearing remotely.
But the Covid-19 pandemic forced change in an age-old profession, nearly overnight. As courthouses around the country continue trials and hearings, and even close completely, courts and attorneys alike have been forced to adopt new technologies at every stage of proceedings.
Strategies and things that will change the way we think and work
Television shows of the 1960’s like The Jetsons predicted that the 21st century would be filled with flying cars, and airborne robots would be a part of our everyday lives. October 21st, 2015 marked the point in time in which Marty McFly (Michael J. Fox) traveled to in Back to the Future Part II, the 1989 sequel to the time-travelling classic. The future he found was one which had captured the imagination of millions — instead today, we live in a world dominated by live streaming, smartphones and social networks, not flying cars or hover boards (maybe, because is this really a hover board?).
Within the span of 10 short years, or perhaps even less, service apps like Uber, Lyft, DoorDash, AirBnB and others have spawned millions of users, and can be found on almost everyone’s smart phone. Personal assistants like Siri and Alexa have entered many of our lives. It would be terribly naive for anyone to say that the world hasn’t changed in the last 10 years. This technology growth and change is likely to continue for the next decade and beyond.
It’s the roaring 20’s baby! At the start of the millennium, Information Technology was deeply concerned about Y2K … “Oh no, the zeroes and the clocks!” When the clocks struck 12 in 2000, the iPhone, Twitter, Facebook, 4k, 5G, and all the other fun things we know today didn’t exist. So what’s in store as a new decade begins?

Efficient quantum computing is expected to enable advancements that are impossible with classical computers. Scientists from Japan and Sydney have collaborated and proposed a novel two-dimensional design that can be constructed using existing integrated circuit technology. This design solves typical problems facing the current three-dimensional packaging for scaled-up quantum computers, bringing the future one step closer.
Quantum computing is increasingly becoming the focus of scientists in fields such as physics and chemistry, and industrialists in the pharmaceutical, airplane, and automobile industries. Globally, research labs at companies like Google and IBM are spending extensive resources on improving quantum computers, and with good reason. Quantum computers use the fundamentals of quantum mechanics to process significantly greater amounts of information much faster than classical computers. It is expected that when error-corrected and fault-tolerant quantum computation is achieved, scientific and technological advancement will occur at an unprecedented scale.
But building quantum computers for large-scale computation is proving to be a challenge in terms of their architecture. The basic units of a quantum computer are the “quantum bits” or “qubits.” These are typically atoms, ions, photons, subatomic particles such as electrons, or even larger elements that simultaneously exist in multiple states, making it possible to obtain several potential outcomes rapidly for large volumes of data. The theoretical requirement for quantum computers is that these are arranged in two-dimensional (2-D) arrays, where each qubit is both coupled with its nearest neighbor and connected to the necessary external control lines and devices. When the number of qubits in an array is increased, it becomes difficult to reach qubits in the interior of the array from the edge. The need to solve this problem has so far resulted in complex three-dimensional (3-D) wiring systems across multiple planes in which many wires intersect, making their construction a significant engineering challenge.
Researchers unveil electronics that mimic the human brain in efficient learning

Only 10 years ago, scientists working on what they hoped would open a new frontier of neuromorphic computing could only dream of a device using miniature tools called memristors that would function/operate like real brain synapses.
But now a team at the University of Massachusetts Amherst has discovered, while on their way to better understanding protein nanowires, how to use these biological, electricity conducting filaments to make a neuromorphic memristor, or “memory transistor,” device. It runs extremely efficiently on very low power, as brains do, to carry signals between neurons. Details are in Nature Communications.
Most quantum computers being developed around the world will only work at fractions of a degree above absolute zero. That requires multi-million-dollar refrigeration and as soon as you plug them into conventional electronic circuits they’ll instantly overheat.
But now researchers led by Professor Andrew Dzurak at UNSW Sydney have addressed this problem.
“Our new results open a path from experimental devices to affordable quantum computers for real world business and government applications,” says Professor Dzurak.
The researchers’ proof-of-concept quantum processor unit cell, on a silicon chip, works at 1.5 Kelvin—15 times warmer than the main competing chip-based technology being developed by Google, IBM, and others, which uses superconducting qubits.
Flexible mechanical sensors that can be bonded or sewn into woven or knitted fabrics have been developed by German research lab Fraunhofer ISC.
Deformation, force and pressure can be measured, and strains up to 100% (doubling length) can be endured.
It is an elastomer film with flexible electrodes on both sides. Electrode patterning can be used to create an array of sensors. Silicone rubber is the preferred elastomer, with chemical cross-linking allowing hardness to be tuned.
“The textile-integrated sensors are washable, show a high wearing comfort and are reasonable in price,” said the lab. “They are applicable in medical devices, for preventing bed sores or for localising the pressure distribution in shoes, for example. They can also support personal training by measuring the posture via the clothes, or as an input device for game and fitness device controlling.”
