Absorbing acoustics with soundless spirals

Researchers at CNRS and University of Lorraine develop a coiled-up acoustic metasurface that achieves total acoustic absorption in very low-frequency ranges. The absorber's deep-subwavelength thickness enables it to handle large wavelengths with reduced size structure, making it physically practical for most applications.

Superconductivity: Footballs with no resistance

Researchers from Max Planck Institute achieve light-induced lossless electricity transmission in fullerenes, contributing to the search for practical superconducting materials. The discovery could lead to a better understanding of high-temperature superconductivity and the development of artificial superconductors.

Stronger evidence found for link between prenatal exposure to paracetamol and the risk of developing

Research found a consistent link between prenatal paracetamol exposure and asthma development, with the strongest association seen in children who had been exposed for multiple complaints. The study, the largest of its kind, also found no strong evidence for an association between maternal or paternal paracetamol use outside pregnancy.
