Designable spatially coherent wideband radiation and frequency conversion – BIOENGINEER.ORG

Components of a typical laser include gain medium, laser pumping energy and resonant optical cavity. The output frequency of most lasers is fixed or within a small range, and it is difficult to generate lasers of some frequencies by common ways. Regarding some practical applications, optical frequency conversion technology which can convert the laser into … Read more

Virtual CT scans cut patient radiation exposure in half during PET/CT studies – BIOENGINEER.ORG

Vancouver, British Columbia, Canada (Embargoed until 3:00 pm PDT, Sunday, June 12, 2022)—A novel artificial intelligence method can be used to generate high-quality “PET / CT” images and subsequently decrease radiation exposure to the patient. Developed by the National Cancer Institute, the method bypasses the need for CT-based attenuation correction, potentially allowing for more frequent … Read more

Sun Science: How the sneaky nature of ultraviolet light works

ROCHESTER, NY (WROC) – Being exposed to harmful ultraviolet (UV) rays from the sun is the reason we get sunburned from time to time. FUN FACT: Did you know that while UV rays are invisible to humans, some insects such as bumblebees can see them? UV rays sourced from the sun are subdivided into different … Read more

Henry Ford Health is first in the world to offer latest advancement in MR-guided radiation therapy – BIOENGINEER.ORG

DETROIT (June 2, 2022) – Henry Ford Health is the first in the world to complete a full course of patient treatments using the latest advancement in magnetic resonance (MR) -guided radiation therapy, which integrates real-time magnetic resonance imaging (MRI ) and linear acceleration to deliver precise and accurate radiation treatment more rapidly than ever … Read more

Meta-analysis shows targeted radiation therapy may be as effective as standard care for small cell lung cancer patients with brain metastases

A study published in The Lancet Oncology suggests that targeted radiation therapy is equitable to the current standard of care for patients whose lung cancer has metastasized to the brain. A study published in The Lancet Oncology suggests that targeted radiation therapy is equitable to the current standard of care for patients whose lung cancer … Read more

Researchers identify the cuticle as the first protective barrier of plants against UV radiation

Researchers identified the cuticle as the first protective barrier of plants against UV radiation. Credit: University of Malaga The cuticle, the outermost part of a plant, which acts as the interphase between the plant and the environment, is becoming increasingly important in agriculture. It has already been shown that the cuticle has hydrological properties to … Read more

Alpha particles and alpha radiation explained

Alongside beta particles, gamma rays, and neutrons, alpha particles are a type of radiation, also called alpha radiation. As with most forms of radiation, alpha particles are emitted from radioactive elements. Alpha particles are relatively heavy and slow compared to their companions, so they pose little danger to humans unless ingested. They are, however, frequently … Read more

Huge Solar Flare Bursting From The Sun Is Second of Its Kind This Week, NASA Says

A powerful solar flare just erupted from the surface of the Sun – and NASA captured stunning footage of it. The X-class flare, the strongest produced by our star, was recorded by NASA’s Solar Dynamics Observatory as it burst from a sunspot on the lower left limb of the Sun at 9:25 am EDT (13:25 … Read more

Something’s Glowing at The Galactic Core, And We Could Be Closer to Solving The Mystery

Something deep in the heart of the Milky Way galaxy is glowing with gamma radiation, and nobody can figure out for sure what it might be. Colliding dark matter has been proposed, ruled out, and then tentatively reconsidered. Dense, rapidly rotating objects called pulsars were also considered as candidate sources of the high-energy rays, before … Read more
