~“May you live in interesting times”~

Having the blessing and the curse of working in the field of cybersecurity, I often get asked about my thoughts on how that intersects with another popular topic — artificial intelligence (AI). Given the latest headline-grabbing developments in generative AI tools, such as OpenAI’s ChatGPT, Microsoft’s Sydney, and image generation tools like Dall-E and Midjourney, it is no surprise that AI has catapulted into the public’s awareness.

Doug Millay, Ph.D., a scientist with the Division of Molecular Cardiovascular Biology at Cincinnati Children’s has dedicated his career to revealing the most fundamental mechanisms of skeletal muscle development. He has been a leader in characterizing how two “fusogens” called Myomaker and Myomerger mediate the entry of stem cells into mature muscle cells to build the tissue that humans depend upon for movement, breathing, and survival.

Now, some of the basic discoveries made by Millay and colleagues are translating into a potential treatment for people living with Duchenne muscular dystrophy (DMD). Their latest research, published April 12, 2023, in the journal Cell, reveals that in mice, modified viruses, engineered with Myomaker and Myomerger, result in specific fusion with . These viruses can therefore be used as a vector to deliver a vital gene needed for that is mutated in people with DMD.

A key unknown prior to this work was whether proteins like Myomaker and Myomerger, which mainly function on cells, could even work on viruses. First author Sajedah Hindi, Ph.D., also with the Division of Molecular Cardiovascular Biology at Cincinnati Children’s and a leading member of the research team, took on the challenge to test this idea.

Time travel has long been a popular theme in movies, but scientists believe that the concept of time teleportation is unlikely in reality. However, they do not dismiss the possibility of time travel altogether. The laws of physics suggest that time travel may be possible, but the details are complex.

Physicists explain that traveling to the near future is relatively simple, as we are all doing it right now at a rate of one second per second. Additionally, Einstein’s special theory of relativity states that the speed at which we move affects the flow of time. In other words, the faster we travel, the slower time passes. Furthermore, Einstein’s general theory of relativity suggests that gravity also impacts the flow of time. The stronger the nearby gravity, the slower time goes.

“It was very curiosity-driven,” says Isak Engquist, a professor at Linköping University who led the effort. “We thought: ‘Can we do it? Let’s do it, let’s put it out there to the scientific community and hope that someone else has something where they see these could actually be of use in reality.’”

“I have colleagues who are at the forefront in a field we call electronic plants. … We have worked with dead woods for this project, but the next step might be to integrate it also into living plants.” —Isak Engquist, Linköping University.

Even though the wooden transistor still awaits its killer app, the idea to build wood-based electronics is not as crazy as it sounds. A recent review of wood-based materials reads, “Around 300 million years of tree evolution has yielded over 60,000 woody species, each of which is an engineering masterpiece of nature.” Wood has great structural stability while being highly porous and efficiently transporting water and nutrients. The researchers leveraged these properties to create conducting channels inside the wood’s pores and electrochemically modulate their conductivity with the help of a penetrating electrolyte.

A developer release of Microsoft’s Edge browser has a new address bar advertisement for the company’s Bing AI — but it only appears when the user goes to its main competitor’s site at bard.google.com.

Microsoft’s Edge can be a great Chromium browser alternative to Google’s Chrome, but the former is displaying some annoying new rivalry antics: advertising Microsoft’s Bing AI chatbot while you’re trying out Google’s Bard AI. As pointed out by developer and Twitter user Vitor de Lucca, a new developer version of Edge will now display a new Bing ad next to the Google Bard URL.

Microsoft adds a Bing AI ad to Edge’s address bar when trying Google Bard.

VC firms including Tiger Global, Sequoia Capital, Andreessen Horowitz, Thrive and K2 Global picking up new shares, according to documents seen by TechCrunch. A source tells us Founders Fund is also investing. Altogether the VCs have put in just over $300 million at a valuation of $27 billion — $29 billion.

Updated to note that the Microsoft investment closed in January. The money from VCs reported here, part of a tender offer, is separate to that.

OpenAI, the startup behind the widely used conversational AI model ChatGPT, has picked up new backers, TechCrunch has learned.

There is a new war happening online: the browser war. Tech companies everywhere are seeking to integrate AI in browsers in an attempt to please and attract users looking for the best possible search experience.

This is according to a new article by FOX Business published on Friday.

This phenomenon was amplified with Microsoft’s announcement earlier this year that it would roll out a new AI-powered version of its Bing search engine and Edge web browser that will incorporate OpenAI’s ChatGPT.

“The new capability of low thermal budget growth on an 8-inch scale enables the integration of this material with silicon CMOS technology and paves the way for its future electronics application.”

With our pockets and houses filling with electronic gadgets and AI and Big Data fueling the rise of data centers, there is a need for more computer chips— more powerful, potent, and denser than ever.

These chips are traditionally made with boxy 3D materials bulky in nature, making stacking these into layers difficult.
