In addition, the […]

Moving due to unaffordable housing may jeopardize healthcare

LOS ANGELES (Dec. 30, 2020) — People who move due to unaffordable housing are at increased risk of failing to receive the medical care they need, according to a new study from Cedars-Sinai and the University of California, Los Angeles. The study, published online in the Journal of General Internal Medicine, concludes that the result […]

Dating apps don’t destroy love

Mobile apps have revolutionised the way people meet in Switzerland and elsewhere in recent years. Unlike traditional dating sites, these apps do not feature detailed user profiles but are largely based on rating photos using a swipe review system. As dating apps escalated in popularity, so has criticism about them encouraging casual dating only, threatening […]

Use of the delivery system in mouse models results in unprecedented siRNA penetration across the intact blood brain barrier Technology could offer potential for a variety of human neurological disorders In the past few decades, researchers have identified biological pathways leading to neurodegenerative diseases and developed promising molecular agents to target them. However, the translation […]

a new method for fluorescence microscopy — ScienceDaily

Fluorescence microscopy is widely used in biochemistry and life sciences because it allows scientists to directly observe cells and certain compounds in and around them. Fluorescent molecules absorb light within a specific wavelength range and then re-emit it at the longer wavelength range. However, the major limitation of conventional fluorescence microscopy techniques is that the […]

Putty-like composites of gallium metal with potential for real-world application

Gallium is a highly useful element that has accompanied the advancement of human civilization throughout the 20th century. Gallium is designated as a technologically critical element, as it is essential for the fabrication of semiconductors and transistors. Notably, gallium nitride and related compounds allowed for the discovery of the blue LED, which was the final […]
