Deep-learning aging clock tracks human aging, detects eye and other diseases from retinal images

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

A team of biomedical researchers has developed a non-invasive, more accurate, and inexpensive “aging clock” for tracking and slowing human aging by examining retinal images and using trained deep-learning models of the eye’s fundus (the deepest area of the eye), using a new “eyeAge” system.

The researchers are affiliated with Buck Institute for Research on Aging, Google Research, Google Health, Zuckerberg San Francisco General Hospital, Post Graduate Institute of Medical Education, and Research (India), and University of California, San Francisco.

Tracking eye changes that accompany aging and age-related diseases: the eyeAge system.

Mind-Controlled Robots: New Graphene Sensors Are Turning Science Fiction Into Reality

Posted by in categories: nanotechnology, particle physics, robotics/AI

Researchers have designed a 3D-patterned, graphene.

Graphene is an allotrope of carbon in the form of a single layer of atoms in a two-dimensional hexagonal lattice in which one atom forms each vertex. It is the basic structural element of other allotropes of carbon, including graphite, charcoal, carbon nanotubes, and fullerenes. In proportion to its thickness, it is about 100 times stronger than the strongest steel.

A new measurement could change our understanding of the universe

Posted by in categories: cosmology, physics

The universe is expanding, but how fast exactly? The answer appears to depend on whether you estimate the cosmic expansion rate—referred to as the Hubble’s constant, or H0—based on the echo of the Big Bang (the cosmic microwave background, or CMB) or you measure H0 directly based on today’s stars and galaxies. This problem, known as the Hubble tension, has puzzled astrophysicists and cosmologists around the world.

A study carried out by the Stellar Standard Candles and Distances research group, led by Richard Anderson at EPFL’s Institute of Physics, adds a new piece to the puzzle. Their research, published in Astronomy & Astrophysics, has achieved the most accurate calibration of Cepheid stars—a type of variable star whose luminosity fluctuates over a defined period—for distance measurements to date based on data collected by the European Space Agency’s (ESA’s) Gaia mission. This new calibration further amplifies the Hubble tension.

The Hubble constant (H0) is named after the astrophysicist who—together with Georges Lemaître—discovered the phenomenon in the late 1920s. It’s measured in kilometers per second per megaparsec (km/s/Mpc), where 1 Mpc is around 3.26 million light years.

YouTuber builds ‘transparent’ jet engine to show how it works

Posted by in category: transportation

YouTuber Warped Perception loves his jet engines. He modifies them all the time and uses them in different scenarios.

Since he is such a fan of the machines, he decided it was time to show his viewers how they work. To do that, he decided to build a see-through engine.

Scientists Find Antibiotic-Free Way to Treat Drug-Resistant Infections

Posted by in category: biotech/medical

Scientists have found an antibiotic-free way of treating ‘golden staph’ skin infections that are the scourge of some cancer patients, and a threat to hospital-goers everywhere.

The lab study from researchers at the University of Copenhagen utilized an artificial version of an enzyme that’s naturally produced by bacteriophages (viruses that infect bacteria), and used it to eradicate Staphylococcus aureus, or golden staph, in biopsy samples from people with skin lymphoma.

“To people who are severely ill with skin lymphoma, staphylococci can be a huge, sometimes insoluble problem, as many are infected with a type of Staphylococcus aureus that is resistant to antibiotics,” explains immunologist Niels Ødum of the University of Copenhagen.

Biological markers identified as powerful predictors of prostate cancer relapse following radiotherapy

Posted by in category: biotech/medical

Two key proteins linked to cell division can reliably predict disease recurrence in prostate cancer after radiotherapy treatment, according to new research.

Using an inexpensive and widely available technique in the clinic, the researchers evaluated a range of proteins in tumor biopsies and determined that the phosphatase and tensin homolog (PTEN) and geminin proteins are key markers associated with cancer relapse after radiotherapy.

Based on their results, the team at The Institute of Cancer Research, London, reported that patients with tumors showing loss of PTEN were almost three times more likely to experience recurrence than those with ‘normal’ PTEN. Similarly, the data showed a 70 percent increase in the likelihood of experiencing recurrence in patients with tumors that had a 10 percent increase in geminin.
