Sunscreen doesn’t protect as well as it could: Here is what is missing

By adding key antioxidants to sunscreens and anti-ageing creams, sun damage will decrease

Add iron-trapping extracts to sunscreen to make it a lot more effective. A key ingredient is missing from all sunscreens and anti-aging creams, and our skin will be far better protected from the damaging effects of the sun once this rich source of natural photoprotection has been added.

This is the finding of a new study into sun-related skin aging carried out at the UK’s University of Bath and published in the journal Antioxidants.

The missing ingredient is a class of antioxidant (a type of stable molecule) commonly found in nature...

Quantum Teleportation: The Express Lane for Quantum Data Traffic

Teleportation may be a concept usually reserved for science fiction, but researchers have demonstrated that it can be used to avoid loss in communication channels on the quantum level.

The team, including researchers from Griffith University’s Centre for Quantum Dynamics, has highlighted the issues around inherent loss that occurs across every form of communication channel (for example, internet or phone) and discovered a mechanism that can reduce that loss.

Professor Geoff Pryde, Dr Sergei Slussarenko, Dr Sacha Kocsis and Dr Morgan Weston, and researchers from The University of Queensland and the Nat...

Neptune is Cooler than we thought: Study reveals unexpected Changes in Atmospheric Temperatures

Observed changes in Neptune’s thermal-infrared brightness, a measure of temperature in Neptune’s atmosphere. The plot shows the relative change in the thermal-infrared brightness from Neptune’s stratosphere with time for all existing images taken by ground-based telescopes. Brighter images are interpreted as warmer. Corresponding thermal-infrared images (top) at wavelengths of ~12 µm show Neptune’s appearance in 2006, 2009, 2018 (observed by the European Southern Observatory’s Very Large Telescope’s VISIR instrument), and 2020 (observed by Subaru’s COMICS instrument). The south pole appears to have become dramatically warmer in just the past few years. Credit: Michael Roman/NASA/JPL/Voyager-ISS/Justin Cowart

Researchers Generate High-Quality Quantum Light with Modular Waveguide Device

 Researchers developed a new waveguide optical parametric amplifier (OPA) module (pictured), which they combined with a specially designed photon detector to generate strongly nonclassical light that can be used for quantum experiments.

New approach could enable faster and more practical optical quantum computers. For the first time, researchers have successfully generated strongly nonclassical light using a modular waveguide-based light source. “Our goal is to dramatically improve information processing by developing faster quantum computers that can perform any type of computation without errors,” said research team member Kan Takase from the University of Tokyo...
