First Observation of One-in-10-Billion Particle Decay Hints at Hidden Physics
Physicists have detected a long-sought particle process that may suggest new forces and particles exist in the universe.
Once in a very great while, an ephemeral particle called a kaon arises and then quickly decays away into three other obscure entities. Whether or not this happens in a particular way has very little bearing on most of us, who will go about our lives without knowing either way. But to physicists who have been searching for this arcane process for decades, it matters a lot; finding out how often it happens could reveal hidden aspects of our universe.
US scientist reveal mouth swab that can gauge your risk of death
U.S. researchers developed CheekAge, a tool that reliably estimates mortality risk.
Researchers in the United States have created a next-generation tool named CheekAge, which uses methylation patterns found in easily obtainable cheek cells.
In a groundbreaking discovery, the team has demonstrated that CheekAge can reliably estimate mortality risk, even when epigenetic data from different tissues are utilized for analysis.
Epigenetic markers are chemical changes to DNA that donât alter the genetic code but can affect how genes work. Methylation is one such change, often linked to aging. Scientists use these patterns to create âage clocksâ that estimate biological age, revealing how fast someone is aging.
New insights into exotic nuclei creation using Langevin equation model
The improved accuracy of MNT reaction predictions provided by this model could facilitate the production of isotopes that are difficult to generate using other methods. These isotopes are valuable for scientific research and medical applications, such as diagnostics and treatments. According to Prof. Zhang, the goal is to keep the model comprehensive yet practical for experimental use.
This development represents a step forward in nuclear physics, contributing to the understanding of exotic nuclei production through MNT reactions. Further refinement of the model may enhance its utility in guiding future research and improving rare isotope production processes.
This research was conducted in collaboration with Beijing Normal University, Beijing Academy of Science and Technology, and the National Laboratory of Heavy Ion Accelerator of Lanzhou.
Headband-like device uses speckle contrast optical spectroscopy to predict stroke risk
A team of researchers from the Keck School of Medicine of USC and California Institute of Technology (Caltech) have developed a potential new way to measure a personâs stroke risk that is cost-effective and noninvasive, akin to a cardiac stress test. If validated through further tests, the device could transform stroke care, making early detection of increased risk a standard part of medical exams around the world.
A new apparatus for analyzing partial coherence in integrated photonic networks
Anyone familiar with optics labs is familiar with the extremes of light coherence: laser beams are highly coherent, producing clear interference patterns used for precise applications like atomic manipulation or precise sensing. In contrast, light from sources like flashlights is incoherent, typically unable to produce such patterns without considerable effort, or at the cost of considerable optical power losses.
New cooling system works on gravity instead of electricity
Its abundance of sunlight and heavy investment in solar cell technology has positioned Saudi Arabia well in its transition to becoming a leading exporter of renewable energy. Indeed, solar energy currently makes up more than 80% of the Kingdomâs green energy capacity. However, these cells bring a twisted irony, as their operation exposes them to overheating risks. Cooling systems are therefore necessary, but many depend on electricity.
An international research team led by KAUST Professor Qiaoqiang Gan has designed a potential solution. Their device needs no electricity, as it extracts water from the air using nothing more than gravity and relies on cheap, readily available materials.
Along with keeping the solar cells and other semiconductor technologies cool, the water can be repurposed for irrigation, washing, cooling buildings on which the solar cells are placed, and other applications.
