X-Ray Of A Single Atom Achieved In World First
Posted by Genevieve Klien in categories: biotech/medical, chemistry
Thinking of X-rays might trigger memories of broken bones or dental check-ups. But this extremely energetic light can show us more than just our bones: it is also used to study the molecular world, even biochemical reactions in real-time. One issue, though, is that researchers have never been able to study a single atom with X-rays. Until now.
Scientists have been able to characterize a single atom using X-rays. Not only were they able to distinguish the type of atoms they were seeing (there were two different ones), but they also managed to study the chemical behavior these atoms were showing.
“Atoms can be routinely imaged with scanning probe microscopes, but without X-rays, one cannot tell what they are made of. We can now detect exactly the type of a particular atom, one atom-at-a-time, and can simultaneously measure its chemical state,” senior author Professor Saw Wai Hla, from the University of Ohio and the Argonne National Laboratory, said in a statement.

Scientists Uncover a Surprising Link Between Pure Mathematics and Genetics
Posted by Genevieve Klien in categories: bioengineering, biotech/medical, encryption, evolution, genetics, mathematics
An interdisciplinary team of mathematicians, engineers, physicists, and medical scientists has discovered a surprising connection between pure mathematics and genetics. This connection sheds light on the structure of neutral mutations and the evolution of organisms.
Number theory, the study of the properties of positive integers, is perhaps the purest form of mathematics. At first sight, it may seem far too abstract to apply to the natural world. In fact, the influential American number theorist Leonard Dickson wrote “Thank God that number theory is unsullied by any application.”
And yet, again and again, number theory finds unexpected applications in science and engineering, from leaf angles that (almost) universally follow the Fibonacci sequence, to modern encryption techniques based on factoring prime numbers. Now, researchers have demonstrated an unexpected link between number theory and evolutionary genetics.

Fourth Dimension Breakthrough: New Metamaterial Controls Energy Waves
Posted by Paul Battista in categories: energy, engineering
Scientists engineered a synthetic metamaterial to direct mechanical waves along a specific path, which adds an innovative layer of control to 4D reality, otherwise known as the synthetic dimension.
Everyday life involves the three dimensions or 3D — along an X, Y, and Z axis, or up and down, left and right, and forward and back. But, in recent years scientists like Guoliang Huang, the Huber and Helen Croft Chair in Engineering at the University of Missouri, have explored a “fourth dimension” (4D), or synthetic dimension, as an extension of our current physical reality.
Creation of a new synthetic metamaterial.

Omicron variant resembles other respiratory viruses, posing challenges for syndromic surveillance
Posted by Shubham Ghosh Roy in categories: biotech/medical, surveillance
In a recent article published in Scientific Reports, researchers describe the symptom profiles of respiratory viral infections from the Flu Watch Community and the Virus Watch cohort studies to compare the frequency of the range of symptoms experienced during influenza, respiratory syncytial virus (RSV), rhinovirus, seasonal coronaviruses (CoVs) infections, and infections from severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) wild-type (wt) strain and variants of concerns (VOCs), including Alpha, Delta, Omicron BA1/BA2/BA5.

Elon Musk Says Mark Zuckerberg’s Threads ‘Committed The Cardinal Sin’ Of Boring People To Death
Posted by Kelvin Dafiaghor in categories: electronics, Elon Musk
As Meta Platforms Inc.’s META latest social media platform, Threads’ daily active user count continues to drop, Elon Musk has accused Mark Zuckerberg’s forum of committing a “cardinal sin.”
What Happened: Meta’s Threads entered the social media arena with much fanfare, quickly attracting over 100 million sign-ups in just five days.
However, the initial hype didn’t translate into long-term user retention, as the daily active user count witnessed a staggering 82% decline since its peak at 44 million users on launch day, reported CNN, citing data from Sensor Tower.

AI.com once took you to ChatGPT. Now, it goes to Elon Musk’s xAI
Posted by Kelvin Dafiaghor in categories: Elon Musk, robotics/AI
Will someone please tell us who the hell owns AI.com and what they’re doing with it?
The domain, which used to direct to ChatGPT, now redirects users to xAI, an AI company owned by Elon Musk. Separate from X Corp, xAI claims on its website that it “will work closely with X,” the social media company formerly known as Twitter — including using posts on X as training for its large language model.
The high-value AI.com domain name changed hands in 2021, sat idle for a while, and then suddenly started redirecting to ChatGPT in February. For ChatGPT users, it was a helpful shortcut if they didn’t have the site bookmarked and couldn’t quite remember the precise URL for the chatbot (chat.openai.com, for the record).
