Atomically purchasing digital files with digital currency is an idea that has a long history in this space. Digital goods, digital money, the two seem like a perfect pairing together. Digital goods, i.e. information, are also massive markets. Think about all the video, audio, text, games, and other forms of digital content that people purchase and consume on a regular basis. These are markets worth billions and billions of dollars that people interact with on a daily basis. Most of the serious attempts at implementing paid file sharing have gone down bad roads. Filecoin was an attempt to do this…

The United States House Financial Services Subcommittee on Digital Assets, Financial Technology and Inclusion received an education in the uses of blockchain technology in a hearing titled “Crypto Crime in Context: Breaking Down the Illicit Activity in Digital Assets” on Nov. 15. The hearing was bipartisan in nature, chair French Hill stated at the outset. Hill began the meeting by citing an article published by The Wall Street Journal on Oct. 10 on the use of crypto by Hamas for fundraising. The article was corrected on Oct. 27 to reflect more accurately crucial data produced by blockchain analytics firm Elliptic, as…

Commercial Crew Program’s Plaque Hanging Tradition Continues, Celebrating Work Done by Marshall Team By Celine Smith NASA’s Marshall Space Flight Center participated in a new tradition last December to honor engineers for their exceptional efforts on CCP (Commercial Crew Program) missions to the International Space Station continued Nov. 13, with a third plaque hanging at the HOSC (Huntsville Operations Support Center). Team members are nominated at Marshall, Johnson Space Center, and Kennedy Space Center – centers that support CCP – to hang the plaque of the mission they supported. David Gwaltney, LVSO (Launch Vehicle Systems Office) technical assistant, was selected…

Transporter-9 lifts off. Image credit: SpaceX. SpaceX concluded another successful Transporter ridesharing mission on Saturday (November 11), with Transporter-9 carrying over 110 satellites and payloads into orbit for companies including Planet Labs, GHGSat, and FoxConn into orbit following a successful launch at Vandenberg Air Force base in California.  Transporters, Launchers, and Tugs The “Transporter” SmallSat ridesharing missions are intended to democratize access to space by bundling together a large number of small satellites, many of them comparatively tiny CubeSats and NanoSats, in one large mission aboard a Falcon 9 Block 5 launcher.  By waiting for a Transporter mission instead of…

Starship, which stands 394 feet (120 meters) tall, produces 16.7 million pounds (74.3 Meganewtons) of thrust, more than double that of the Saturn V rockets used to send Apollo astronauts to the Moon. The US Federal Aviation Administration (FAA) on Wednesday authorized SpaceX to carry out its second launch of Starship, the most powerful rocket ever built, after a first attempt in April ended in a spectacular explosion. In a statement, the FAA said Elon Musk’s company had now “met all safety, environmental, policy and financial responsibility requirements” following the mishap that marred the first orbital test flight of its…

Our DNA is not indestructible. Throughout the course of our lives, DNA can break in response to natural and environmental factors. Thankfully, our bodies have dedicated enzymes and pathways which can glue our broken DNA back together through several different mechanisms, known as DNA repair pathways. Some cancers, however, can hijack these pathways for their own benefit. Susanna Stroik, PhD, and Dale Ramsden, PhD, both researchers in the Department of Biochemistry and Biophysics in the UNC School of Medicine and the UNC Lineberger Comprehensive Cancer Center, have pieced together the lesser-known DNA repair pathway, called polymerase theta-mediated end joining (TMEJ).…

NASA Administrator Bill Nelson announced Wednesday Jim Free’s promotion to associate administrator for the agency at NASA Headquarters in Washington, effective when his predecessor Bob Cabana retires on Sunday, Dec. 31. Since September 2021, Free has served as the associate administrator for NASA’s Exploration Systems Development Mission Directorate (ESDMD).   Nelson also announced Free’s deputy, Catherine Koerner, will succeed him as the next head of the mission directorate.  “So many of us in the NASA family have worked with Jim and have been inspired by his character and intellect. Pam, Bob, and I strongly believe that his wealth of experience and…

A quick scan of the headlines makes it seem like generative artificial intelligence is everywhere these days. In fact, some of those headlines may actually have been written by generative AI, like OpenAI’s ChatGPT, a chatbot that has demonstrated an uncanny ability to produce text that seems to have been written by a human. But what do people really mean when they say “generative AI?” Before the generative AI boom of the past few years, when people talked about AI, typically they were talking about machine-learning models that can learn to make a prediction based on data. For instance, such…

On the other hand, coding today is a highly skilled, well-paid job, and there’s some concern that AI could effectively automate it. Nadella argues that skilled programmers will remain in demand, but that their jobs will change and even more jobs will become available. Nadella has said he envisions 1 billion developers creating on its platforms, many of them with little to no previous experience with coding.    Anytime you have something as disruptive as this, you have to think about the displacement and causes. And that means it’s all about upskilling and reskilling, and in an interesting way, it’s more…
