4dThe vision of the future of miniaturization has produced a series of synthetic molecular motors that are driven by a range of energy sources and can carry out various movements. A research group at Friedrich-Alexander-Universität Erlangen-Nürnberg (FAU) has now managed to control a catalysis reaction using a light-controlled motor. This takes us one step closer to realizing the vision of a nano fa
Scientists observe directed energy transport between neighboring molecules in a nanomaterial
4dWhen light falls on a material, such as a green leaf or the retina, certain molecules transport energy and charge. This ultimately leads to the separation of charges and the generation of electricity. Molecular funnels, so-called conical intersections, ensure that this transport is highly efficient and directed.

4dWater can be in two liquid states under cold temperatures, shows new research. The scientists used x-ray lasers and computer simulations. The discovery has applications across a variety of fields due to water's ubiquity. Water is an essential life force for humanity and our planet. But despite it's omnipresence, there's much we have still to learn about the fateful combination of hydrogen and oxy

The Guardian view on coronavirus and vaccine scepticism: time to act | Editorial
5dPlans for mass immunisation against Covid-19 are developing fast, but concerns must be addressed In the 1960s, academics studying rumours drew inspiration from epidemiology. They noted how such stories spread through communities, "infecting" some individuals while others seemed immune, and how more resistant populations could stop their spread. Their insights have in turn been taken up by health

New solvent-based recycling process could cut down on millions of tons of plastic waste
5dMultilayer plastic materials are ubiquitous in food and medical supply packaging, particularly since layering polymers can give those films specific properties, like heat resistance or oxygen and moisture control. But despite their utility, those ever-present plastics are impossible to recycle using conventional methods.

Eddie Yeadon obituary
5dMy brother Eddie Yeadon, who has died aged 82, was an engineer and physicist with a particular interest in optics and astronomy. In the late 1960s he worked in the US for the optics company Perkin Elmer on the visors for the helmets used in the Apollo 11 moon landings. He also designed a reflector left on the moon to "bounce" a laser beam. He often joked that this was the part of the mission whic

MMR vaccine could protect against COVID-19, study shows
5dThe measles-mumps-rubella (MMR) vaccine has been theorized to provide protection against COVID-19. In a new study, researchers provide further proof of this by showing that mumps IgG titers, or levels of IgG antibody, are inversely correlated with severity in recovered COVID-19 patients previously vaccinated with the MMR II vaccine.
