We’ve tested filters from Sawyer, Katadyn, LifeStraw, MSR and more to find the best option for every adventure. O recorte ajuda a contextualizar a pauta dentro de Tech.

Much like camera settings—filters, flashes and focus—affect what we notice in a final photo, the way scientists measure something can affect how we interpret and understand it. This is especially true when imaging things that we can't see on our own, such as activity in the human

Research from the University of Granada published in the European Journal of Pediatrics has revealed that girls with higher levels of bisphenol A (a component of plastics and epoxy-phenolic resins) and benzophenones (ultraviolet filters) in their urine are more likely to experien

Physicists and instrument makers in Leiden have succeeded in optimizing a spring that almost completely filters out vibrations at temperatures near absolute zero. This breakthrough opens the door to a new generation of highly sensitive experiments. The research is published in th

Nanomechanical resonators are miniature vibrating structures on chips that oscillate at frequencies ranging from a few kilohertz to gigahertz. They are used as ultrasensitive detectors of mass and force, temperature and pressure, and as components in radio frequency filters and o
