Airborne

Carbon dioxide is key to how long airborne viruses hang around in the air and, therefore, their likelihood of spreading. Opening a window may be a more scientific way to avoid the spread of respiratory viruses than first anticipated.

A review article has presented 10 key scientific reasons why the virus that causes COVID-19 is predominantly spread though the air. The research adds to a growing chorus of experts saying the evidence for airborne transmission is “overwhelming”.

A team of Belgian scientists has developed what is billed as the most sensitive "electronic nose" yet. The chemical sensor detects pesticides and nerve gases and has a design that could see it integrated with electronics such as your smartphone.

NASA scientists are eager to get to grips with a new toy for observing the heavens, the Echelon-Cross-Echelle Spectrograph (EXES). Mounted on a heavily-customized Boeing 747, the spectrograph will detect wavelengths unavailable from sources either on land or in space.

Scientists at the University of Hertfordshire have developed what they say is the world’s first portable, real-time airborne asbestos detector.

Research conducted at University of California, Riverside has resulted in an "electronic nose" prototype that can "smell" small amounts of harmful airborne materials.

The Emergency Bra is a protective device that transforms from a bra into two respiratory pace masks to filter out harmful airborne particles.

For the first time an airborne laser (ABL) weapon mounted aboard a modified Boeing 747 has shot down a ballistic missile.

Researchers at Tel Aviv University (TAU) have developed a sensor called ‘Dust Alert’ that provides real-time contamination levels in terms of dust, pollen and toxins within the home or office.

Earlier this month, the Airborne Laser system finally got a chance to prove its worth by locating, tracking and successfully firing on a target missile.
