Ray Kurzweil is known for making predictions in technology that have come true — and now he is sure humans will reach immortality in our lifetime. He also explains how robots will make it happen.
Researchers have for the first time characterised the molecular mechanism of the early stages of programmed cell death or apoptosis, a process which plays a crucial role in the prevention of cancer.
The study, published today (2 June) in Science Advances, was led by Dr Luke Clifton at the Science and Technology Facilities Council (STFC) ISIS Neutron and Muon Source (ISIS) in Oxfordshire. They worked alongside partners at the University of Umea and European Spallation Source in Sweden.
It is the most recent in a series of research collaborations by this team, investigating the cellular proteins responsible for apoptosis.
The largest conference on aging in the biopharmaceutical industry is set to take place 28 August – 1 September 2023 on-site in Copenhagen and online.
Longevity. Technology: The United Nations report that the proportion of people aged over 65 now outnumber children younger than 5. This substantial surge in the elderly populace presents a formidable healthcare challenge for societies across the globe, and it is evident that comprehensive and transformative approaches aimed at mitigating age-related illnesses and vulnerabilities will play a pivotal role in addressing the health and socioeconomic obstacles associated with an aging society. Once again this year, ARDD – now in its tenth year – is set to feature some of the most foremost experts in longevity, who will impart their latest insights on the process of aging and how we target the aging process to maximise lifespan and healthspan.
At ARDD, leaders in the aging and longevity field will describe the latest progress in the molecular, cellular and organismal basis of aging and the search for interventions, making it one of the must-attend events in the longevity space.

The mammalian retina is a complex system consisting out of cones (for color) and rods (for peripheral monochrome) that provide the raw image data which is then processed into successive layers of neurons before this preprocessed data is sent via the optical nerve to the brain’s visual cortex. In order to emulate this system as closely as possible, researchers at Penn State University have created a system that uses perovskite (methylammonium lead bromide, MAPbX3) RGB photodetectors and a neuromorphic processing algorithm that performs similar processing as the biological retina.
Panchromatic imaging is defined as being ‘sensitive to light of all colors in the visible spectrum’, which in imaging means enhancing the monochromatic (e.g. RGB) channels using panchromatic (intensity, not frequency) data. For the retina this means that the incoming light is not merely used to determine the separate colors, but also the intensity, which is what underlies the wide dynamic range of the Mark I eyeball. In this experiment, layers of these MAPbX3 (X being Cl, Br, I or combination thereof) perovskites formed stacked RGB sensors.
The output of these sensor layers was then processed in a pretrained convolutional neural network, to generate the final, panchromatic image which could then be used for a wide range of purposes. Some applications noted by the researchers include new types of digital cameras, as well as artificial retinas, limited mostly by how well the perovskite layers scale in resolution, and their longevity, which is a long-standing issue with perovskites. Another possibility raised is that of powering at least part of the system using the energy collected by the perovskite layers, akin to proposed perovskite-based solar panels.
Researchers have for the first time characterized a unique molecular mechanism of the early stages of programmed cell death or apoptosis, a process which plays a crucial role in prevention of cancer.
The study, which is published June 2, 2023 in Science Advances, was led by Dr. Luke Clifton at the STFC ISIS Neutron and Muon Source (ISIS) in Oxfordshire, alongside co-lead Professor Gerhard Gröbner at the University of Umeå and partners at the European Spallation Source in Sweden. It is the most recent in a series of research collaborations by this team, investigating the cellular proteins responsible for apoptosis.
Apoptosis is essential for human life, and its disruption can cause cancerous cells to grow and not respond to cancer treatment. In healthy cells, it is regulated by two proteins with opposing roles known as Bax and Bcl-2.
Surprisingly, the human studies consistently show that collagen supplements reverse the signs of skin aging.

Don’t try finding Zuzalu on a map; it doesn’t exist anymore. It was a “pop-up city” conceived by the tech entrepreneur Vitalik Buterin, creator of Ethereum, and a group of like-minded people to facilitate co-living and collaboration in fields like crypto, network states, AI, and longevity. It was also, in substantial part, funded by Vitalik.
Zuzalu, located on the Adriatic coast of Montenegro, began its short history on March 25 and wound down on May 25. It was a complex and memorable phenomenon, and I’m wrapping my mind around a larger article in the works.
Usually, I don’t eat breakfast due to my intermittent fasting regimen, but in Zuzalu, breakfast, served at a particular local restaurant, was the healthiest meal of the day. Also, it was free (kudos to Vitalik, and more on that later). Most importantly, it was the place to meet new people.
A groundbreaking manifesto on living better and longer that challenges the conventional medical thinking on aging and reveals a new approach to preventing chronic disease and extending long-term health, from a visionary physician and leading longevity expert.
“One of the most important books you’ll ever read.”—Steven D. Levitt, New York Times bestselling author of Freakonomics
Wouldn’t you like to live longer? And better? In this operating manual for longevity, Dr. Peter Attia draws on the latest science to deliver innovative nutritional interventions, techniques for optimizing exercise and sleep, and tools for addressing emotional and mental health.
