A drop of blood and a crank are enough to learn your blood type in a minute
A drop of finger-prick blood, a plastic chip and a crank: after a minute you can see the blood type and how many red cells the blood contains. Taiwanese researchers want to give this to paramedics; for now it is a prototype.
A drone flies among moving obstacles with a mathematical proof of safety
MIT researchers built a program that steers a drone among moving obstacles even though the machine does not know its surroundings. The authors prove mathematically that, under stated assumptions, the drone will not collide.
A graphene membrane removes half the caffeine from coffee
An Australian–Japanese team shows a graphene oxide membrane that cuts about half the caffeine from coffee in the lab while keeping flavour-related compounds. This is not yet decaf coffee or a factory line — more a filter instead of solvent chemistry.
Scientists built a sensor network in the body without radio
Researchers in Atlanta show that a pulse through the body wakes a distant implant. That lets the device be smaller than a pea and sleep on almost no power.
Scientists watched a glowing film survive chip lithography
In Zurich they made a screen material that can be cut with light like in a chip factory — and it still glows. That may mean denser images in glasses and phones.
Scientists watched a sudden fade of vibration on a chip
Scientists at Stanford learned to watch live how a tiny plate loses vibration suddenly. It is a step toward more sensitive sensors and finer control of sound.
