Van Wassenbergh et al. use high-speed video analyses and biomechanical models to show that woodpecker heads do not function as shock absorbers as commonly assumed, but as stiff hammers to aid pecking performance.

FDA is asking industry and other interested parties for additional safety data on 12 active sunscreen ingredients currently available in marketed products.

New research by a team at Pennsylvania State University suggests that microbes in the human gut could be harnessed to help the body absorb useful nutritional metals—like iron, which is critical for red blood cells—and block or even remove the absorption of toxic ones, like mercury. The group presents their findings at ASM Microbe 2023, the annual meeting of the American Society for Microbiology.

In a study published in Advanced Materials Interfaces, a research team led by Prof. Wang Hui and associate Prof. Sheng Zhigao from the Hefei Institutes of Physical Science (HFIPS) of the Chinese Academy of Sciences reported the synthesis of polyvinylpyrrolidone-directed nickel nanowires (PNNWs) via solvothermal method assisted by a high magnetic field, and applied them to enhance microwave absorption.

I'm wondering if drinking coffee while taking vitamins will affect the efficiency and efficacy of how the vitamins are absorbed. Is it better to eat vitamins first, wait a little, then drink coffee? If so, how long should one wait? Comments URL: https://news.ycombinator.com/item?id=34533384 Points: 1 # Comments: 1

Researchers from the Shanghai Institute of Optics and Fine Mechanics (SIOM) of the Chinese Academy of Sciences have recently proposed a design concept for a tunable broadband perfect absorber based on non-split coupling of Epsilon-near-zero (ENZ) and localized surface plasmon resonance (LSPR) modes.

Parent company Interpublic Group folds Philadelphia-based Tierney into Carmichael Lynch.

Electrical engineers at Duke University have determined the theoretical fundamental limit for how much electromagnetic energy a transparent material with a given thickness can absorb. The finding will help engineers optimize devices designed to block certain frequencies of radiation while allowing others to pass through, for applications such as stealth or wireless communications.

Scientists from University of Regensburg, Massachusetts Institute of Technology, Moscow institute of Physics and Technology, and University of Kansas have discovered abnormally strong light absorption in graphene. The effect arises from the conversion of ordinary electromagnetic waves into super-slow surface waves running through graphene. The observation is of fundamental interest and shows in an impressive way…

Photonic systems are quickly gaining traction in many emerging applications, including optical communications, lidar sensing, and medical imaging. However, the widespread adoption of photonics in future engineering solutions hinges on the cost of manufacturing photodetectors, which, in turn, largely depends on the kind of semiconductor utilized for the purpose.
