Alzheimer’s disease is a disease that attacks the brain, causing a decline in mental ability that worsens over time. It is the most common form of dementia and accounts for 60 to 80 percent of dementia cases. There is no current cure for Alzheimer’s disease, but there are medications that can help ease the symptoms.
Researchers in the field of optical spectrometry have created a better instrument for measuring light. This advancement could improve everything from smartphone cameras to environmental monitoring.
The research, led by Finland’s Aalto University, developed a powerful, incredibly small spectrometer that fits on a microchip and is run by artificial intelligence. Their research was recently published in the journal Science.
The study used a relatively new class of super-thin materials known as two-dimensional semiconductors, and the result is a proof of concept for a spectrometer that could be easily integrated into a number of technologies such as quality inspection platforms, security sensors, biomedical analyzers, and space telescopes.
The first scientific results from the new Facility for Rare Isotope Beams (FRIB) at Michigan State University have been unveiled by physicists in the US. Heather Crawford at Lawrence Berkeley National Laboratory and colleagues have synthesized new neutron-rich isotopes of three different elements. Each nuclei is near the neutron drip line and the team has measured the isotopes’ lifetimes for the first time. The research provides a taste of how physicists will use FRIB to study exotic nuclei.

Costing $730m, FRIB opened earlier this year with the aim of expanding our knowledge of nuclear physics by creating thousands of new isotopes for scientists to study. FRIB comprises a superconducting linear accelerator that can create high-intensity beams of just about every stable isotope. These nuclei are fired at targets, creating unstable isotopes that are collected to form beams – allowing the isotopes to be studied.
Join the audience for a Women in Medical Physics live webinar at 3 p.m. GMT/10 a.m. EST on 14 December 2022 exploring how to begin a new MR-Linac program for MRIdian in your radiation oncology department.
MRIdian is the world’s first radiation therapy system to integrate a diagnostic-quality MRI with an advanced linear accelerator and the only system with MR-guided, real-time, 3D, multiplanar soft-tissue tracking and automated beam control. MRIdian offers precise and personalized care through on-table adaptive treatments without the need for fiducials. The technological foundations of MRIdian allows for the delivery of ablative dose with tighter margins in five or fewer fractions, all while maintaining low to no toxicity. With tens of thousands of patients treated, and an ever-growing body of clinical evidence, MRIdian is leading the MRI-guided revolution in radiation therapy.
Scientists link dozens of new genome sites to coronary artery disease risk and pioneer a powerful method for illuminating the biological roots of common disease.
Robots that can monitor conditions in a hive, do a waggle dance, or even infiltrate the queen’s court could help scientists influence the health of a colony.
A technique that uses nanoscale structures to reproduce colour has been employed to make copies of famous paintings, and could also help fight counterfeiting.
NASA has shared remarkable footage showing its Orion spacecraft passing over the lunar surface at an altitude of just 687 miles.
X-ray diffraction measurements under laser-driven dynamic compression allow researchers to investigate the atomic structure of matter at hundreds of thousands of atmospheres of pressure and temperatures of thousands of degrees, with broad implications for condensed matter physics, planetary science and astronomy.
Pressure determination in these experiments often relies on velocimetry measurements coupled with modeling that requires accurate knowledge of the optical and thermomechanical properties of a window material, resulting in significant systematic uncertainty.
In new research published in Physical Review B, Lawrence Livermore National Laboratory (LLNL) scientists report on a series of X-ray diffraction experiments on five metals dynamically compressed to 600 GPa (6,000,000 atmospheres of pressure). In addition to collecting atomic structure information for multiple compressed samples, the team demonstrated a different approach for pressure determination applicable to X-ray diffraction experiments under quasi-isentropic ramp compression.
