Elon Musk completes $44bn Twitter takeover — and immediately sacks top executives

Posted by in categories: biotech/medical, Elon Musk, security

I guess it’s time for Twitter execs to go home, and for me to start using Twitter again. They killed my chamber of commerce account, then when I opened a personal account, they kept asking for my phone number every time I logged in. If I give you my number once and you send me an sms, I’m not giving it to you again, as that’s not safe.


It ends months of bad blood between the two parties regarding the takeover, with Elon Musk complaining about fake accounts on the platform and claims by a whistleblower that Twitter misled regulators about security risks.

Facebook to share traders’ data with State agencies

Posted by in categories: business, government

Meanwhile, in Kenya, Facebook to start sharing advertising data with Kenya’a tax agency, and the police.


In the terms, the company said businesses placing adverts across its different platforms would have given it consent to share information with government agencies looking for such information to assist in lawful investigations.

“Our licence to deliver your ad will end when we have completed your order. You understand, however, that…you consent that Meta may disclose your advertising content, and all information associated with your advertising, to a governmental entity or body if Meta believes that disclosure would assist in a lawful investigation,” says the company in the terms that will be effective January 3, 2023.

Scientists Successfully Reverse Premature Aging

Posted by in categories: biotech/medical, genetics, life extension

Werner Syndrome and Hutchinson Gilford Progeria Syndrome are two examples of the rare genetic disorders known as progeroid syndromes that cause signs of premature aging in children and young adults. Patients with progeroid syndromes have pathologies and symptoms that are often linked to aging, including osteoporosis, cataracts, heart disease, and type II diabetes.

This aging is characterized by the gradual loss of nuclear architecture and an underlying tissue-specific genetic program, but the causes are unclear. Scientists have discovered a potential new target for treating these syndromes by preventing nuclear architecture loss.

How AI image generators could help robots

Posted by in categories: internet, robotics/AI

AI image generators, which create fantastical sights at the intersection of dreams and reality, bubble up on every corner of the web. Their entertainment value is demonstrated by an ever-expanding treasure trove of whimsical and random images serving as indirect portals to the brains of human designers. A simple text prompt yields a nearly instantaneous image, satisfying our primitive brains, which are hardwired for instant gratification.

Although seemingly nascent, the field of AI-generated art can be traced back as far as the 1960s with early attempts using symbolic rule-based approaches to make technical images. While the progression of models that untangle and parse words has gained increasing sophistication, the explosion of generative art has sparked debate around copyright, disinformation, and biases, all mired in hype and controversy.

Research team proposes unclonable, invisible machine vision markers using cholesteric spherical reflectors

Posted by in categories: augmented reality, blockchains, economics, mobile phones, physics, robotics/AI, wearables

Over the last three decades, the digital world that we access through smartphones and computers has grown so rich and detailed that much of our physical world has a corresponding life in this digital reality. Today, the physical and digital realities are on a steady course to merging, as robots, Augmented Reality (AR) and wearable digital devices enter our physical world, and physical items get their digital twin computer representations in the digital world.

These digital twins can be uniquely identified and protected from manipulation thanks to crypto technologies like blockchains. The trust that these technologies provide is extremely powerful, helping to fight counterfeiting, increase supply chain transparency, and enable the circular economy. However, a weak point is that there is no versatile and generally applicable identifier of physical items that is as trustworthy as a blockchain. This breaks the connection between the physical and digital twins and therefore limits the potential of technical solutions.

In a new paper published in Light: Science & Applications, an interdisciplinary team of scientists led by Professors Jan Lagerwall (physics) and Holger Voos (robotics) from the University of Luxembourg, Luxembourg, and Prof. Mathew Schwartz (architecture, construction of the built environment) from the New Jersey Institute of Technology, U.S., propose an innovative solution to this problem where physical items are given unique and unclonable fingerprints realized using cholesteric spherical reflectors, or CSRs for short.

New compact and dexterous robotic finger that can withstand physical impacts

Posted by in category: robotics/AI

For decades researchers have worked to design robotic hands that mimic the dexterity of human hands in the ways they grasp and manipulate objects. However, these earlier robotic hands have not been able to withstand the physical impacts that can occur in unstructured environments. A research team has now developed a compact robotic finger for dexterous hands, while also being capable of withstanding physical impacts in its working environment.

The team of researchers from Harbin University of Technology (China) published their work in the journal Frontiers of Mechanical Engineering on October 14, 2022.

Study explores how visual effects in videogames help players to make sense of game worlds

Posted by in categories: computing, entertainment

Visual effects (VFX) can help to make videogames more engaging and immersive for players. However, they are often also designed to support players, for instance, by pointing them to specific locations or highlighting helpful game features.

Researchers at University of California, Santa Cruz (UCSC) have recently carried out a study investigating the ways in which VFX can help videogame players to make sense of the virtual worlds and environments they are navigating. Their paper, pre-published on arXiv and presented at the IEEE VIS Workshop on Visualization for the Digital Humanities (VIS4DH), could guide the future development of both and data visualization tools.

“Our study mostly builds upon our engagement with two distinct communities: the data visualization research and the videogame communities,” Henry Zhou, one of the researchers who carried out the study, told TechXplore. “The Computational Media department at UCSC has a mixture of scholars interested in both media artifacts. The paper originated from my colleague Angus G. Forbes’ observation of a general minimalist aesthetic as practicing wisdom in the data visualization research community, especially when it comes to visual effects (VFX) and animation.”

A telltale protein spreads throughout the brain in distinct patterns based on patients’ Alzheimer’s phenotype

Posted by in categories: biotech/medical, neuroscience

New imaging of patients with Alzheimer’s demonstrates how a telltale protein spreads throughout the brain based on the phenotype of the disease, i.e., whether the condition is dominated by forgetfulness, or atrophy in a specific brain region. The research offers a host of illuminating clues that ultimately may inform new treatment strategies.

The protein is known as tau and a large multi-disciplinary team of brain researchers at McGill University in Montreal has been able to trace the protein’s patterns in living patients via magnetic resonance imaging (MRI). Alzheimer’s disease is intimately linked to tau, which can form tangles in the brain that irrevocably damage neurons.

The patterns detected by McGill scientists apparently are unique to the phenotype of Alzheimer’s afflicting the patient. This staggering finding opens an intriguing new window into the molecular mechanisms of the disease. And while many features of Alzheimer’s are the same from one patient to the next, phenotypes are a hallmark of the condition. Tracking tau patterns is a specialty of the scientists at McGill, who found that the intrinsic connectivity of the human brain itself provides the scaffolding for the aggregation of tau in distinct variants of the disease.
