Bryan Johnson, a millionaire tech entrepreneur dedicated to reversing ageing, recently took to social media to boast about his “super clean plasma.” In a detailed post on X, he shared that a lab technician couldn’t bring himself to dispose of the plasma after a total plasma exchange (TPE) procedure.

Johnson claims to have reduced his epigenetic age through his comprehensive regimen called Project Blueprint. He follows a strict diet and exercise routine, spends over $2 million annually on a team of doctors and medical equipment, and undergoes both experimental and conventional treatments-including the recent TPE procedure.

TPE, a procedure often used in regenerative medicine and anti-ageing treatments, involves replacing a patient’s plasma with donor plasma or a substitute fluid. In Johnson’s case, his plasma was replaced with albumin.

Micelles are spherical molecular structures usually formed by amphiphilic molecules with block structure, which contain both hydrophilic and hydrophobic parts. The hydrophobic tails of these molecules cluster together to form a core, while the hydrophilic heads face outward, creating a protective shell. This structure allows micelles to encapsulate hydrophobic substances within their core and disperse them in a water-based environment.

Magnetic resonance imaging (MRI) has long been a cornerstone of modern medicine, providing highly detailed images of internal organs and tissues. MRI machines, those large, tube-shaped magnets commonly found in hospitals, use powerful magnets to map the densities of water and fat molecules within the body.

A major challenge in realizing quantum computers is the development of quantum error correction technology. This technology offers a solution for addressing errors that occur in the qubit, the basic unit of quantum computation, and prevents them from being amplified during the computation.

Researchers from the Department of Energy’s Oak Ridge National Laboratory have taken a major step forward in using quantum mechanics to enhance sensing devices, a new advancement that could be used in a wide range of areas, including materials characterization, improved imaging and biological and medical applications.

The second ATLAS study, presented recently at the 17th International Workshop on Top Quark Physics, broke new ground by providing the first dedicated ATLAS measurement of how often top-quark pairs are produced along with jets originating from charm quarks (c-jets).

ATLAS physicists analyzed events with one or two leptons (electrons and muons), using a custom flavor-tagging algorithm developed specifically for this study to distinguish c-jets from b-jets and other jets. This algorithm was essential because c-jets are even more challenging to identify than b-jets, as they have shorter lifetimes and produce less distinct signatures in the ATLAS detector.

The study found that most theoretical models provided reasonable agreement with the data, though they generally underpredicted the production rates of c-jets. These results, which for the first time separately determined the cross-sections for single and multiple charm-quark production in top-quark-pair events, highlight the need for refined simulations of these processes to improve future measurements.

Thin-film lithium niobate is an emerging nonlinear integrated photonics platform ideally suited for quantum applications. Through spontaneous parametric down-conversion (SPDC), it can generate correlated photon pairs for quantum key distribution, teleportation, and computing.
