“We need to go to space to help us here on Earth. Satellites have played an enormous role in improving the state of the world, and will do even more”.

I’m often asked: ‘Why are you building satellites for space when there are so many problems to fix here on Earth?’ It’s a perfectly rational question. The short answer is that we need to go to space to help us here on Earth. Satellites have played an enormous role in improving the state of the world, and will do even more as an explosion of technology innovation enables large new fleets of small satellites to be deployed with radical new capabilities.

The advent of DNA sequencing has given scientists a clearer insight into the interconnectedness of evolution and the web-like path that different organisms take, splitting apart and coming back together. Tony Capra, associate professor of biological sciences, has come to new conclusions about the influence of Neanderthal DNA on some genetic traits of modern humans.

The article “Neanderthal introgression reintroduced functional ancestral alleles lost in Eurasian populations” was published in the journal Nature Ecology & Evolution on July 27.

The ancestors of all modern humans lived across the African continent, until approximately 100,000 years ago when a subset of humans decided to venture further afield. Neanderthals, an extinct relative of modern humans, had been longtime residents of Europe and central and south Asia; their ancestors had already migrated there 700,000 years previously. The humans who moved into central Asia and the Middle East encountered and reproduced with Neanderthals. Neanderthal DNA is present in some modern humans, and now research shows that can sometimes be a good thing.

In a press conference at the University of Chicago, the U.S. Department of Energy (DOE) unveiled a report that lays out a blueprint strategy for the development of a national quantum internet, bringing the United States to the forefront of the global quantum race and ushering in a new era of communications. This report provides a pathway to ensure the development of the National Quantum Initiative Act, which was signed into law by President Trump in December 2018.

Around the world, consensus is building that a system to communicate using quantum mechanics represents one of the most important technological frontiers of the 21st century. Scientists now believe that the construction of a prototype will be within reach over the next decade.

In February of this year, DOE National Laboratories, universities and industry met in New York City to develop the blueprint strategy of a national quantum internet, laying out the essential research to be accomplished, describing the engineering and design barriers and setting near-term goals.

Companies like Google and Facebook don’t have to charge you for their product, because you are the product they’re selling—or at least your data is. One individual’s internet habits, shopping tendencies, and interests aren’t that valuable, but when Google owns that data for the majority of internet users the value is enormous. Like Google and Facebook, Amazon understands how profitable data can be and their Alexa service on Echo devices is one avenue to gather it. MSCHF’s Alexagate is a device you can attach to your Amazon Echo to prevent it from listening to your conversations until you’re ready.

Amazon, like Google and Apple, denies that they use Alexa to spy on customers’ conversations. But there is quite a lot of evidence to the contrary. Even in the unlikely event that they’re telling the truth, Amazon is absolutely tracking your Alexa usage data. The Alexagate device physically prevents an Echo device from hearing anything you’re saying until you deactivate the audio blocking capability in order to intentionally issue a command. This is very similar to Bjørn Karmann’s Project Alias device that we covered a couple of years ago. Project Alias was just a concept prototype, but Alexagate is a real product that you can order right now.

Alexagate is an attractive yellow device that sits on top of your Amazon Echo (first generation through third generation). When you don’t want Amazon listening to you through the Alexa service, the device emits ultrasound pulses through transducers directed towards the Echo’s microphone. Those can’t be heard by the human ear, but they are picked up by the Echo and drown out whatever conversation is happening in the area. When you do want Alexa to listen to you, you just clap three times or tap Alexagate three times to temporarily deactivate the ultrasound transducers. The limited edition Alexagate device costs $99 — possibly more than you spent on the Echo itself, but that’s a small price to pay if you value both your privacy and the convenience that Alexa offers.

Confidential computing is the solution that allows both people and entities to keep data confidential and still put it to use.

SpaceX said Starlink, its nascent satellite internet service, has already seen “extraordinary demand” from potential customers, with “nearly 700,000 individuals” across the United States indicating they are interested in the company’s coming service.

Due to the greater-than-expected interest, SpaceX filed a request with the Federal Communications Commission on Friday — asking to increase the number of authorized user terminals to 5 million from 1 million. User terminals are the devices consumers would use to connect to the company’s satellite internet network.

The request comes about a month and a half after SpaceX updated its Starlink website to allow potential customers to “get updates on Starlink news and service availability in your area.” Registering one’s interest in Starlink service meant simply submitting an email address and postal address, with no fee required to receive updates.

Extensive power outages and satellite blackouts that affect air travel and the internet are some of the potential consequences of massive solar storms. These storms are believed to be caused by the release of enormous amounts of stored magnetic energy due to changes in the magnetic field of the sun’s outer atmosphere—something that until now has eluded scientists’ direct measurement. Researchers believe this recent discovery could lead to better “space weather” forecasts in the future.

“We are becoming increasingly dependent on space-based systems that are sensitive to space weather. Earth-based networks and the electrical grid can be severely damaged if there is a large eruption,” says Tomas Brage, Professor of Mathematical Physics at Lund University in Sweden.

Solar flares are bursts of radiation and charged particles, and can cause geomagnetic storms on Earth if they are large enough. Currently, researchers focus on sunspots on the surface of the sun to predict possible eruptions. Another and more direct indication of increased solar activity would be changes in the much weaker magnetic field of the outer solar atmosphere—the so-called Corona.

The U.S. Department of Energy (DoE) has announced a plan to make a quantum internet it says is virtually unhackable. This is definitely a long-term plan that will require new kinds of engineering and technology, not something that will be implemented next year. Let’s take a look at the concept, the plan the DoE has laid out, and how long it all might take.

Within the framework of quantum mechanics, the network proposed here is pretty intuitive. (That’s a big caveat, though!) The report begins with a surprising notion: Although headlines and research have focused on the power of quantum computing, we’re far away from any practical and recognizable computer powered by quantum phenomena. The idea of a quantum network, the DoE says, is far closer to our reach.
