Quantum nature of hydrogen bonds observed in acid–base complex

Researchers in the US have demonstrated the presence of quantum mechanical effects in acid–base interactions, challenging the Brønsted–Lowry theory. The resultant short hydrogen bond is stabilised by a delocalised proton, which rapidly shuttles between the acid and base molecules and is characterised by highly unusual spectral features.

The Brønsted–Lowry theory was proposed in 1923 and explains acid–base interactions in terms of proton transfer. This theory is one of the cornerstones of chemical understanding and is amongst the first principles taught to school students. But despite a growing appreciation for the limitations of traditional thinking, the surprising discovery of a quantum component to such fundamental reactivity was entirely serendipitous.

‘It was luck,’ admits Daniel Kuroda of Louisiana State University, one of the principal researchers involved in the study. ‘We were looking at the structure of liquids … and saw this paper [about an acid–base mixture] with close to the conductivity of sulfuric acid but no ionisation. We wanted to see what the structure was … so we started looking into the project and then realised that clearly we have something very different.’

ENGAGE Reveals First Look at ‘Link’ Metaverse Platform for Enterprise & Education

ENGAGE, the XR education and enterprise metaverse company, today unveiled its Link social platform which the company calls a “fully featured corporate metaverse.”

Previously codenamed Oasis when it was first revealed in June 2021, the Ireland-based studio calls Link a “professional metaverse,” as it was designed to host persistent virtual worlds which serve as gateways to individual spaces where employees, students and individual users can interact.

The studio published a six-minute first look at Link today, shown below:

New peer-to-peer botnet infects Linux servers with cryptominers

A new peer-to-peer botnet named Panchan appeared in the wild around March 2022, targeting Linux servers in the education sector to mine cryptocurrency.

Panchan is empowered with SSH worm functions like dictionary attacks and SSH key abuse to perform rapid lateral movement to available machines in the compromised network.

At the same time, it has powerful detection avoidance capabilities, such as using memory-mapped miners and dynamically detecting process monitoring to stop the mining module immediately.

FAA requires SpaceX to make environmental adjustments to move forward with its Starship program in Texas

FAA to require SpaceX to write a report of the events of the Mexican and Civil Wars.

If people are wondering why the USA rarely has big construction projects anymore, the FAA is requiring that SpaceX write a report of the events of the Mexican and Civil Wars.

From the text: “The company will also contribute to local education and preservation efforts — including preparing a historical context report of the events of the Mexican War and the Civil War that took place in the area as well as replacing missing ornaments on a local historical marker.”


The FAA said SpaceX will be required to take more than 75 actions to mitigate environmental impacts before the company can receive a launch license.

Boost NAD, Reprogramme Our Cells to be Young Again | Dr David Sinclair Interview Clips

David Sinclair shares another side of himself. Compassion for all people. He wants to make sure that longevity technologies are available for all people, not just for the super wealthy and their pets. He also speaks of emerging elderly populations who can live well up until death rather than suffering for so long, and instead start new careers and hobbies.


Researchers have restored vision in animal by resetting some of the thousands of chemical marks that accumulate on DNA as cells age. The work, by Dr David Sinclair Lab, published in Nature Dec 2020, suggests a new approach to reversing age-related decline, by reprogramming some cells to a ‘younger’ state in which they are better able to repair or replace damaged tissue.

David A. Sinclair, Ph.D. A.O. is a tenured Professor in the Genetics Department at the Blavatnik Institute, Harvard Medical School, Boston & Co-Director of the Paul F. Glenn Center for Biology of Aging Research, honorary Professor at the University of Sydney, and co-founder of the journal Aging. He obtained a BS and a Ph.D. at UNSW, worked as a postdoctoral researcher at M.I.T., was hired at Harvard Medical School in 1999 as an Assistant Professor, and promoted to tenured Professor in 2008. His book Lifespan: Why We Age and Why We Don’t Have To, a NYT bestseller, is published in more than 20 languages.

Dr. Sinclair is an inventor on more than 50 patents, 170 papers, an h-index of 103 & cited 73,000+ times. His more than 40 awards include an Excellence in Teaching Award, Harvard, AFAR Fellowship, the Ellison Medical Foundation Scholarships, Genzyme Outstanding Achievement Award, Telluride Technology Award, Innovator of the Year, MERIT Award, Nathan Shock Award, Denham Harman Award, ASMR Medal, Advance Global Australian, Pioneer Award, TIME100’s most influential people, TIME magazine’s Heathcare 50, Irving Wright Award, AFAR, and is an Officer of the Order of Australia (AO).

This desk microphone makes it painfully clear whether you are muted or not

It’s amazing how simple designs can save you from hours of frustration and embarrassment, even virtually.

Work and School from Home arrangements have forced many people to get used to video meetings, virtual classrooms, and online presentations. As if those weren’t stressful enough already, the horrors of discovering that you have been speaking for the past 10 minutes to half an hour when you’re mic has been on mute all the time only adds to feelings of dread. Unfortunately, computers and software haven’t adjusted yet to these new demands on life, lacking clear indicators on the status of the mic. While there might be some sophisticated and complicated software that could try to guess whether you actually need to be muted or not, it actually takes a dead-simple idea to give that peace of mind at very little extra cost.

SpaceX-Affiliated Group Giving Out Funding for Warp Drive Research

Covering interstellar distances rapidly may still be a distant dream, but it’s now getting unprecedented financial support.

A nonprofit called the Limitless Space Institute, co-founded by former NASA warp drive researcher Harold “Sonny” White and retired astronaut Brian Kelly in 2020, is generating enough excitement — and funding — for the concept that it’s started giving out educational and research grants to schools and universities, as detailed by Universe Today.

The Institute, whose mission statement is to “inspire and educate the next generation to travel beyond our solar system and support the research and development of enabling technologies,” has even picked up some increasingly mainstream support. Take Gwynne Shotwell, the chief operations officer and second-in-command of SpaceX, who joined as an independent advisor in April, joining other bigshots in the aerospace sector including several retired astronauts involved with the venture.

AI’s Threats to Jobs and Human Happiness Are Very Real

There’s a movement afoot to counter the dystopian and apocalyptic narratives of artificial intelligence. Some people in the field are concerned that the frequent talk of AI as an existential risk to humanity is poisoning the public against the technology and are deliberately setting out more hopeful narratives. One such effort is a book that came out last fall called AI 2041: Ten Visions for Our Future.

The book is cowritten by Kai-Fu Lee, an AI expert who leads the venture capital firm Sinovation Ventures, and Chen Qiufan, a science fiction author known for his novel Waste Tide. It has an interesting format. Each chapter starts with a science fiction story depicting some aspect of AI in society in the year 2041 (such as deepfakes, self-driving cars, and AI-enhanced education), which is followed by an analysis section by Lee that talks about the technology in question and the trends today that may lead to that envisioned future. It’s not a utopian vision, but the stories generally show humanity grappling productively with the issues raised by ever-advancing AI.

IEEE Spectrum spoke to Lee about the book, focusing on the last few chapters, which take on the big issues of job displacement, the need for new economic models, and the search for meaning and happiness in an age of abundance. Lee argues that technologists need to give serious thought to such societal impacts, instead of thinking only about the technology.
