Cell phones are as carcinogenic as coffee
Journal of Carcinogenesis, 2011 Scientists from 14 countries met under the auspices of the International Agency for Research on Cancer (IARC) in Lyon, France, in May 2011, and assessed the carcinogenicity of radiofrequency electromagnetic fields (RF-EMF). The discussion and conclusions on the ill effects of radio frequency from cell phones evoked obvious and understandable concern ...

Advanced Materials, EarlyView.This study reports a near‐infrared (NIR) luminescent material (Mg2SiO4:1.5%Cr,5%Li) with efficient (EQE = 48%) ultra‐broadband (FWHM ≈ 2413 cm−1 (226 nm)) NIR emission at 960 nm upon blue‐light excitation. This innovation addresses the low efficiency of long‐wavelength (λmax > 900 nm) NIR‐emitting materials due to the radiationless de‐activation and ...

Mucosa‐Interfacing Capsule for In Situ Sensing the Elasticity of Biological Tissues
Advanced Materials Technologies, Volume 10, Issue 6, March 18, 2025.A fundamental mechanism of palpating soft materials is reported to sense deep tissue elasticity in situ with minimal invasion using the interaction between the robot palpation unit and soft tissues. Both the robot locomotion and elasticity sensing functions are remotely controlled by external magnetic fields, while the sensing data are wirelessly ...
