Novel biomarker catches aging cells in the act

Posted by in categories: biotech/medical, life extension

Mayo Clinic researchers have identified interleukin-23 receptor (IL-23R) as a significant biomarker of cellular senescence and aging in both mice and humans. Experiments show that IL-23R levels in the bloodstream increase with age and can decrease, reflecting senescent cell clearing, with senolytic therapies.

Cellular senescence occurs when cells stop dividing but do not trigger apoptosis mechanisms that would allow them to die naturally. Instead, they are stuck in a zombie-like state, where they still have the urge to feed and carry out metabolic activities, but with increasingly incoherent cell signaling and increased pro-inflammatory cytokine secretions.

Senescent cell activity has been linked to several age-related diseases, including those of the immune, cardiovascular, metabolic, pulmonary, musculoskeletal and neurological systems.

AI: The New Work Ally For Gen-Z

Posted by in categories: business, employment, robotics/AI

AI’s impact extends beyond operational efficiency; it is vital in boosting job satisfaction and retention among hourly workers. Inconsistent scheduling and poor communication have long been pain points for this group, especially as one in five Gen-Z workers juggles multiple jobs (poly-employment). AI will directly address the challenges associated with this shift through predictive scheduling and real-time updates, providing clear and reliable expectations. It’s truly a win-win: When employees are on time, customers receive the quality service they deserve.

The World Economic Forum predicts that 23% of global jobs will change in the next five years due to industry shifts, including AI. Through AI, employees can receive support with ongoing training and development tailored to their unique needs and career goals. By providing accessible, on-demand learning, it empowers workers to upskill and grow within their roles, fostering a sense of progress and fulfillment. These resources are essential for Gen-Z, who prioritize personal growth and are likelier to stay with employers who invest in their development.

As we look toward the future, it’s clear that AI is not just a tool for corporate jobs but also a powerful ally for the hourly workforce. By embracing AI, businesses can meet diverse employee needs, enhance productivity and create work environments that are technologically advanced and genuinely supportive. However, for AI to reach its potential in workplaces, industry-wide standards around data transparency and ethical practices are essential.

The Simple 5-Degree Fix Transforming Fusion Energy

Posted by in categories: nuclear energy, sustainability

Scientists have simulated a groundbreaking solution to boost fusion efficiency by eliminating “slow modes,” unhelpful waves that waste energy during plasma heating.

Using 2D simulations, researchers demonstrated how a slight tilt in the Faraday screen can enhance energy transfer, bringing us closer to sustainable fusion energy.

Heating plasma for fusion: the challenge.

AI And Cybersecurity: The Good, The Bad, And The Future

Posted by in categories: cybercrime/malcode, ethics, information science, robotics/AI

• Ethics: As AI gets more powerful, we need to address ethics such as bias in algorithms, misuse, privacy and civil liberties.

• AI Regulation: Governments and organizations will need to develop regulations and guidelines for the responsible use of AI in cybersecurity to prevent misuse and ensure accountability.

AI is a game changer in cybersecurity, for both good and bad. While AI gives defenders powerful tools to detect, prevent and respond to threats, it also equips attackers with superpowers to breach defenses. How we use AI for good and to mitigate the bad will determine the future of cybersecurity.

Convergent evolution: stick and leaf insects share 20 body features

Posted by in category: evolution

A team of biologists in Montana and Germany has found that, regardless of type, those insects that express a protective stick-or leaf-like appearance all evolved the same basic body parts. In their study, published in the journal Proceedings of the National Academy of Sciences, Romain Boisseau, Douglas Emlen and Sven Bradler measured and compared characteristics from 1,359 stick insects covering 212 stick and leaf species and assessed the possibility of predicting evolutionary change.

Prior evidence has shown that similar physical characteristics can evolve in unrelated creatures, a process called . For this new study, the researchers looked at two specific types of insects to learn more about how convergence works. They discovered that stick-and leaf-imitating insects had all evolved the same 20 basic body features, including body shape, head shape and lobster-like features. In all cases, they noted, the features had evolved to help the insects blend into the background to avoid being eaten by predators.

Something else the team learned was that because the same body parts kept evolving in different insects, they could predict how some modern insects will evolve. The key was looking at the that led to changes that had already occurred. Creatures that live in similar environments, they note, tend to evolve in similar ways, including their means of camouflage. This tends to be the best way to avoid predators.

Scientists use machine learning to develop an opener for a molecular can

Posted by in categories: biotech/medical, robotics/AI

In an era of medical care that is increasingly aiming at more targeted medication therapies, more individual therapies and more effective therapies, doctors and scientists want to be able to introduce molecules to the biological system to undertake specific actions.

Examples are and , which for widespread use need to be both effective and inexpensive. In service of this goal, a trio of researchers has used machine learning to design a way to remove molecules inside a molecular cage. Their study is published in Physical Review Letters.

The research, whose lead author is Ryan K. Krueger of Harvard University, but to which each co-author contributed equally, uses differentiable to design complex reactions to direct the system to specific outcomes.

Tiny Fossilized Embryos Reveal Stunning Details of Life Half a Billion Years Ago

Posted by in category: futurism

Tiny balls of mineral are opening a new window into the history of life on Earth.

These millimeter-sized objects are more than half a billion years old – the fossilized embryos of animals that lived during the early Cambrian period, some 535 million years ago.

They belong to a group called Ecdysozoa, which includes insects, spiders, crustaceans, and worms.
