Masks made of nonwoven fabric performed best in a Japanese supercomputer model of their ability to block virus-carrying respiratory droplets, but other types of masks also showed effectiveness.
A pair of Japanese companies have developed a novel way to be stylish and antiseptic at the same time: a clothing fabric that kills microbes with tiny electric shocks generated by the wearer's movements.
The way mosquitoes avoid obstacles to find their targets while flying in the dark holds the secret to engineering better collision avoidance technology for autonomous aerial drones, a new study proposes.
A Japanese team of researchers has shown that time at Tokyo Skytree’s observatory — around 450 meters above sea level — passes four nanoseconds faster per day than at near ground level.
The finding, based on extremely precise “optical lattice clocks” that only go out of synch by one second every 16 billion years, proves Albert Einstein’s general theory of relativity, which predicts that clocks in a strong gravitational field will tick slower than those in a field with weaker gravity.
