A study is offering the most comprehensive demonstration into how volatile organic compounds can spread throughout indoor environments from cigarette smokers’ clothing and bodies, however, the health risks from this kind of exposure are still unclear.

A new study has found that third-hand smoke – chemical residue from cigarette smoke – can spread more pervasively than previously thought, even moving throughout a seemingly “smoke-free” building. But despite this compelling research the dangers to human health still remain unclear.

Voice assistants are making their way into the modern home in many forms, making it perfectly ok for folks to bark instructions at their lamps, vacuum cleaners and light bulbs. The latest household item to gain this functionality is the smoke detector.

​NASA has sent two research aircraft and a bunch of scientists to the Namibian coast to provide a better understanding how aerosols interact with clouds, and how cloud behavior is directly or indirectly changed.

"Smart" smoke and CO2 detectors can do all sorts of clever things, but what if you’ve already got a perfectly good "dumb" detector that you don’t want to replace? Well, you’ll soon be able to give it some brains, in the form of the Roost battery.

While a smoke detector can certainly provide you with an early warning in the event of a house fire, it can't usually do much to help you get out of the building. The Saver, however, allows users to breathe safely in smoke-filled environments, while also serving as a flashlight and alarm.

The idea of getting caught in a building fire is terrifying. The 5aver won't help douse the flames, but the grab-and-go combination of lantern, alarm and mask is designed to help you find your way to safety in a hurry.

The Sense+ is a smartphone dock that packs built-in smoke and gas detection sensors to sound an alert in the event of fire.

A vibrating helmet that uses ultrasound to detect walls and other obstacles is being designed to help guide firefighters through smoke-filled rooms.

Scientists have created what they claim is the world's first secondhand tobacco smoke sensor that records data in real time.
