Precise manipulation and transportation of micro-sized droplets is a challenging task, yet crucial for biomedical and industrial applications. A research team led by a scholar from the City University of Hong Kong (CityU) has successfully developed a novel droplet manipulation method called “WRAP” which can transport droplets of different sizes and compositions by electromagnets or programmable electromagnetic fields. The research team believes that this innovative method has great potential in developing next-generation microfluidics and in the detection of respiratory droplets bearing COVID-19 and other pathogens landed on the surface.

Researchers at the University of Copenhagen have found several hundred different chemical substances in tap water stored in reusable plastic bottles. Several of these substances are potentially harmful to human health. There is a need for better regulation and manufacturing standards for manufacturers, according to the chemists behind the study.

• Innovative remote monitoring system of environmental factors developed for ultra-sensitive quantum devices reliant on stable conditions • Provides blueprint for operating quantum technology in inaccessible environments, such as space or underground • A further step towards AI and human collaboration crucial in the delivery of more complex quantum technologies

At the centre of spiral galaxies – those near to us but also those billions of light-years away – there is a vast spherical region made up of dark matter particles. This region has two defining characteristics: a density that is constant out to a certain radius that amazingly expands over time, while the density decreases. This suggests the existence of a direct interaction between the elementary particles that make up the dark matter halo and those that make up ordinary matter – protons, electrons, neutrons, and photons. This hypothesis is in direct conflict with the current prevailing theory used to describe the universe known as Lambda-Cold Dark Matter – which posits that particles of cold dark matter are inert and do not interact with any other particle except gravitationally.
