German drone technology startup Wingcopter has raised a $22 million Series A – its first significant venture capital raise after mostly bootstrapping. The company, which focuses on drone delivery, has come a long way since its founding in 2017, having developed, built and flown its Wingcopter 178 heavy-lift cargo delivery drone using its proprietary and patented tilt-rotor propellant mechanism, which combines all the benefits of vertical take-off and landing with the advantages of fixed-wing aircraft for longer-distance horizontal flight.

This new Series A round was led by Silicon Valley VC Xplorer Capital, as well as German growth fund Futury Regio Growth. Wingcopter CEO and founder Tom Plümmer explained in an interview that the addition of an SV-based investor is particularly important to the startup, since it’s in the process of preparing its entry into the U.S., with plans for an American facility, both for flight testing to satisfy FAA requirements for operational certification, as well as eventually for U.S.-based drone production.

Wingcopter has already been operating commercially in a few different markets globally, including in Vanuatu in partnership with Unicef for vaccine delivery to remote areas, in Tanzania for two-way medical supply delivery and in Ireland where it completed the world’s first delivery of insulin by drone beyond visual line of sight (BVLOS), the industry’s technical term for when a drone flies beyond the visual range of a human operator who has the ability to take control in case of emergencies.

This tech could be more practical than tokamaks.

Two competing nuclear fusion companies, each with venture capital superstars as major investors, say we’re approaching the “Kitty Hawk moment” for their technology as early as 2025.

We are creating compelling homegrown solutions in education, health care, agriculture, infrastructure, financial services and new commerce,” Ambani said in his speech. “Each of these solutions, once proven in India, will be offered to the rest of the world to address global challenges.

Mukesh Ambani has spent years trying to turn his inherited oil business into a tech empire. In 2020, that pivot really kicked into overdrive.

Researchers at Columbia Engineering report today that they have developed the first nanomaterial that demonstrates “photon avalanching,” a process that is unrivaled in its combination of extreme nonlinear optical behavior and efficiency. The realization of photon avalanching in nanoparticle form opens up a host of sought-after applications, from real-time super-resolution optical microscopy, precise temperature and environmental sensing, and infrared light detection, to optical analog-to-digital conversion and quantum sensing.

“Nobody has seen avalanching behavior like this in nanomaterials before,” said James Schuck, associate professor of mechanical engineering, who led the study published today by Nature. “We studied these new nanoparticles at the single-nanoparticle level, allowing us to prove that avalanching behavior can occur in nanomaterials. This exquisite sensitivity could be incredibly transformative. For instance, imagine if we could sense changes in our chemical surroundings, like variations in or the actual presence of molecular species. We might even be able to detect coronavirus and other diseases.”

Avalanching processes—where a cascade of events is triggered by series of small perturbations—are found in a wide range of phenomena beyond snow slides, including the popping of champagne bubbles, nuclear explosions, lasing, neuronal networking, and even financial crises. Avalanching is an extreme example of a nonlinear process, in which a change in input or excitation leads to a disproportionate—often disproportionately large—change in output signal. Large volumes of material are usually required for the efficient generation of nonlinear optical signals, and this had also been the case for photon avalanching, until now.

Elon Musk just became the richest person in the world, with a net worth of more than $185 billion.

Thursday’s increase in Tesla’s share price pushed Musk past Jeff Bezos, who had been the richest person since 2017 and is currently worth about $184 billion. Musk’s wealth surge over the past year marks the fastest rise to the top of the rich list in history — and is a dramatic financial turnaround for the famed entrepreneur who just 18 months ago was in the headlines for Tesla’s rapid cash burn and his personal leverage against the company’s stock.

Musk started 2020 worth about $27 billion, and was barely in the top 50 richest people.

Chinese scientists have established the world’s first integrated quantum communication network, combining over 700 optical fibers on the ground with two ground-to-satellite links to achieve quantum key distribution over a total distance of 4600 kilometers for users across the country. The team, led by Jianwei Pan, Yuao Chen, Chengzhi Peng from the University of Science and Technology of China in Hefei, reported in Nature their latest advances towards the global, practical application of such a network for future communications.

Unlike conventional encryption, quantum communication is considered unhackable and therefore the future of secure information transfer for banks, power grids and other sectors. The core of quantum communication is quantum key distribution (QKD), which uses the quantum states of particles—e.g. photons—to form a string of zeros and ones, while any eavesdropping between the sender and the receiver will change this string or key and be noticed immediately. So far, the most common QKD technology uses optical fibers for transmissions over several hundred kilometers, with high stability but considerable channel loss. Another major QKD technology uses the free space between satellites and ground stations for thousand-kilometer-level transmissions. In 2016, China launched the world’s first quantum communication satellite (QUESS, or Mozi/Micius) and achieved QKD with two ground stations which are 2600 km apart.

Venezuela’s government is planning to move to a fully digital economy as hyperinflation has made worthless bolivar notes practically disappear, and dollarization expands through the local financial system.

The U.S. dollar has operated as an escape valve for Venezuela amid U.S. sanctions and collapsing oil revenues, President Nicolas Maduro said in a televised interview with Telesur on Friday. He said 18.6% of all commercial transactions are in dollars, while 77.3% are carried out in bolivars with debit cards. Only 3.4% are paid with bolivar notes.

“They have a war against our physical currency. We are moving this year to a more profound digital economy, in expansion. I’ve set the goal of an economy that’s 100% digital,” Maduro said, adding that physical money will eventually disappear.

Movie ratings can determine a movie’s appeal to consumers and the size of its potential audience. Thus, they have an impact on a film’s bottom line. Typically, humans do the tedious task of manually rating a movie based on viewing the movie and making decisions on the presence of violence, drug abuse and sexual content.

Now, researchers at the USC Viterbi School of Engineering, armed with artificial intelligence tools, can rate a movie’s content in a matter of seconds, based on the movie script and before a single scene is shot. Such an approach could allow movie executives the ability to design a movie rating in advance and as desired, by making the appropriate edits on a script and before the shooting of a single scene. Beyond the potential financial impact, such instantaneous feedback would allow storytellers and decision-makers to reflect on the content they are creating for the public and the impact such content might have on viewers.

Using artificial intelligence applied to scripts, Shrikanth Narayanan, University Professor and Niki & C. L. Max Nikias Chair in Engineering, and a team of researchers from the Signal Analysis and Interpretation Lab (SAIL) at USC Viterbi, have demonstrated that linguistic cues can effectively signal behaviors on violent acts, drug abuse and sexual content (actions that are often the basis for a film’s ratings) about to be taken by a film’s characters.
