Researchers at Lund University in Sweden have developed an algorithm that combines data from a simple blood test and brief memory tests, to predict with great accuracy who will develop Alzheimer’s disease in the future.
A study in ‘Nature Communications’ combines data from blood analyses and information about physical exercise to identify a new measure influencing “biological age.”
An iPhone app that estimates biological aging discovered that life expectancy has the capacity to be almost double the current norm.
GEYLANG, Singapore — Have you made any plans for the 22nd century yet? A new study finds you might want to think about it because it’s possible for humans to live to see their 150th birthday!
Scientists in Singapore have developed an iPhone app that accurately estimates biological aging. It discovered that life expectancy has the capacity to be almost double the current norm. The findings are based on blood samples from hundreds of thousands of people in the United States and United Kingdom.
The instrument, called DOSI, uses artificial intelligence to work out body resilience, the ability to recover from injury or disease. DOSI, which stands for dynamic organism state indicator, takes into account age, illnesses, and lifestyles to make its estimates.
Google and national hospital chain HCA will work to develop algorithms to help improve operating efficiency, monitor patients and guide doctors’ decisions.
The protein that lets algae respond to light also partially restored a man’s eyesight.

Researchers developed a “pan-coronavirus” vaccine, designed to protect against many different strains of coronaviruses known to infect humans and bats.
UCL researchers have created a strange robotic “third thumb” that attaches to the hand and adds a large extra digit on the opposite side of the hand from the thumb. Researchers found that using the robotic thumb can impact how the hand is represented in the brain. For the research, scientists trained people to use an extra robotic thumb and found they could effectively carry out dexterous tasks such as building a tower of blocks using a single hand with two thumbs.
Researchers said that participants trained to use the extra thumb increasingly felt like it was part of their body. Initially, the Third Thumb was part of a project seeking to reframe the way people view prosthetics from replacing a lost function to becoming an extension of the human body. UCL Professor Tamar Makin says body augmentation is a growing field aimed at extending the physical abilities of humans.
Four private astronauts have been strapped into a centrifuge, climbing mountains and learning how to fly a spacecraft ahead of their flight to space — the first-ever crewed space mission without any “professional astronauts” on board.
The crew is preparing to launch this upcoming September as part of the Inspiration4 mission aboard a SpaceX Crew Dragon spacecraft. The mission, privately chartered by billionaire Jared Isaacman to support St. Jude Children’s Research Hospital, recruited three crew members in addition to Isaacman for the trip which will fly around the Earth for several days. The crew includes Isaacman, St. Jude physician’s assistant and childhood bone cancer survivor Hayley Arcenaux, data engineer Chris Sembroski and geoscientist, science communicator and artist Sian Proctor.
Researchers identify a mechanism that could lead to new treatments for brain injuries caused by oxygen deprivation.
In a surprising discovery, researchers at Massachusetts General Hospital (MGH) identified a mechanism that protects the brain from the effects of hypoxia, a potentially lethal deprivation of oxygen. This serendipitous finding, which they report in Nature Communications, could aid in the development of therapies for strokes, as well as brain injury that can result from cardiac arrest, among other conditions.
However, this study began with a very different objective, explains senior author Fumito Ichinose, MD, PhD, an attending physician in the Department of Anesthesia, Critical Care and Pain Medicine at MGH, and principal investigator in the Anesthesia Center for Critical Care Research. One area of focus for Ichinose and his team is developing techniques for inducing suspended animation, that is, putting a human’s vital functions on temporary hold, with the ability to “reawaken” them later. This state of being would be similar to what bears and other animals experience during hibernation. Ichinose believes that the ability to safely induce suspended animation could have valuable medical applications, such as pausing the life processes of a patient with an incurable disease until an effective therapy is found. It could also allow humans to travel long distances in space (which has frequently been depicted in science fiction).
2 sticks of RAM giving you 1TB of memory will be the norm soon.
While consumers today typically use computers with 8GB or 16GB of DDR4 RAM inside, Samsung is pushing ahead with the next generation of memory modules. Its latest stick of RAM is a 512GB DDR5 module running at 7200Mbps.
The new module will be used in servers performing “the most extreme compute-hungry, high-bandwidth workloads.” That means supercomputers, artificial intelligence, and machine learning. It was made possible thanks to advanced HKMG technology, which Samsung adopted back in 2018 for its GDDR6 memory. Basically, HKMG replaces the insulator layer in DRAM structures. The high dielectric material contained in the layer reduces current leakage and therefore allows higher performance. At the same time, Samsung managed to reduce power usage in the new module by 13%.
“Samsung is the only semiconductor company with logic and memory capabilities and the expertise to incorporate HKMG cutting-edge logic technology into memory product development,” said Young-Soo Sohn, Vice President of the DRAM Memory Planning/Enabling Group at Samsung Electronics. “By bringing this type of process innovation to DRAM manufacturing, we are able to offer our customers high-performance, yet energy-efficient memory solutions to power the computers needed for medical research, financial markets, autonomous driving, smart cities and beyond.”
