Airborne microorganisms, including fungi and bacteria, are major contributors to indoor air pollution, with growing links to respiratory diseases. In a recent study, scientists from Korea explored the health effects of common airborne microbes by testing their toxicity in mice and calculating human-equivalent exposure limits. The results revealed that some fungi can cause lung inflammation and injury even at concentrations below current guideline levels, highlighting the need for species-specific indoor air quality standards.

How is ventilation at various depth layers of the Atlantic connected and what role do changes in ocean circulation play? Researchers from Bremen, Kiel and Edinburgh have pursued this question and their study has been published in the professional journal Nature Communications.

A team of scientists has developed a powerful new way to detect subtle magnetic signals in common metals like copper, gold, and aluminium—using nothing more than light and a clever technique. Their research, recently published in the prestigious journal Nature Communications, could pave the way for advances in everything from smartphones to quantum computing.

A new material platform has enabled scientists to create photon pairs whose entanglement can be tuned, from a layer thinner than a human hair. The photon pairs are created by a metasurface made of indium gallium phosphide (InGaP), which has a nonlinear response that can split a classical photon into two quantum photons. By tuning the wavelength of the initial photon, the two new photons can be generated as fully entangled through their polarisation, not entangled at all, or any value in between, with picosecond control.
