Artificial Intelligence Unlocks New Possibilities in Anti-Aging Medicine
A recent paper published in Nature Aging by researchers from Integrated Biosciences, a biotechnology company combining synthetic biology and machine learning.
Machine learning is a subset of artificial intelligence (AI) that deals with the development of algorithms and statistical models that enable computers to learn from data and make predictions or decisions without being explicitly programmed to do so. Machine learning is used to identify patterns in data, classify data into different categories, or make predictions about future events. It can be categorized into three main types of learning: supervised, unsupervised and reinforcement learning.
Does Cathie Wood Have Her Hands on the Next Big Semiconductor Stock?
Ark Invest, which is led by CEO Cathie Wood, has been pouring money into semiconductor stocks lately and has made another notable purchase. According to portfolio updates published by the firm yesterday, Wood’s company has increased its investment in Quantum-Si (QSI-6.20%) — a small-cap biotech with a specialized, chip-based platform for protein sequencing.
Ark Invest regularly publishes information about stocks that have been bought and sold for its exchange-traded funds (ETFs), and a recent update showed it purchased more than 1.4 million shares of Quantum-Si stock for its Ark Genomic Revolution ETF (ARKG-1.84%) on Thursday. The purchase would have been valued at roughly $3.7 million based on the stock’s price at market close yesterday, and is the largest investment that Ark has made in the healthcare-tech upstart’s stock so far.
So the question is: Why is Wood excited about this little-known life sciences player?
Has humanity defeated ageing? Scientists strike ‘single pill’ breakthrough
Scientists have achieved a major breakthrough in combating ageing and age-related diseases. The study by the researchers from Harvard Medical School and Massachusetts Institute of Technology was published in the journal Aging-US.
Humanity’s attempt to prevent ageing: What is the breakthrough?
The researchers have introduced a chemical method through a ‘single pill’ to reprogram body cells, following which the cells effectively return to a younger state.

Alzheimer’s diagnosis revamp embraces rating scale similar to cancer
July 16 (Reuters) — Alzheimer’s disease experts are revamping the way doctors diagnose patients with the progressive brain disorder — the most common type of dementia — by devising a seven-point rating scale based on cognitive and biological changes in the patient.
The proposed guidelines, unveiled by experts on Sunday in a report issued at an Alzheimer’s Association conference in Amsterdam, embrace a numerical staging system assessing disease progression similar to the one used in cancer diagnoses. They also eliminate the use of terms like mild, moderate and severe.
The revamp — replacing guidelines issued in 2018 — was prompted by the increased availability of tests detecting key Alzheimer’s-related proteins such as beta amyloid in the blood and new treatments that require confirmation of disease pathology prior to use.
People With Complete Color Blindness Given Their First Sight of Color
A small selection of volunteers who were completely color blind can now faintly detect a splash of color following retinal gene therapy.
Following the trial by researchers in Israel, three adults and one child who could only sense brightness of light found that after gene therapy they were able to tell a red object apart from its darker background.
Achromatopsia is caused by defects in genes that control cone cells, our eyes’ color-sensors. The approximately 1 in 30,000 people affected see all the vibrant colors of the world as blurry shades of gray.
Researchers develop self-sensing electric artificial muscles
In a study published recently in Advanced Intelligent Systems, researchers from Queen Mary University of London have made significant advancements in the field of bionics with the development of a new type of electric variable-stiffness artificial muscle that possesses self-sensing capabilities. This innovative technology has the potential to revolutionize soft robotics and medical applications.
Muscle contraction hardening is not only essential for enhancing strength but also enables rapid reactions in living organisms. Taking inspiration from nature, the team of researchers at QMUL’s School of Engineering and Materials Science has successfully created an artificial muscle that seamlessly transitions between soft and hard states while also possessing the remarkable ability to sense forces and deformations.
Dr. Ketao Zhang, a Lecturer at Queen Mary and the lead researcher, explains the importance of variable stiffness technology in artificial muscle-like actuators. “Empowering robots, especially those made from flexible materials, with self-sensing capabilities is a pivotal step towards true bionic intelligence,” says Dr. Zhang.

Doctors re-attach boy’s head post-car accident with ‘amazing’ surgery
Doctors in Israel have re-attached a boy’s head after he was hit by a car while riding his bike.
Twelve-year-old Palestinian Suleiman Hassan, from the West Bank, suffered an internal decapitation — where the base of the skull and the top of the spine become detached, but the skin is still intact.
Decapitation is the total separation of the head from the body. Internal decapitation occurs when sudden impact to the head causes the ligaments and muscles holding the skull in position on the top vertebrae of the spine to tear.
