That's 'sew' smart! Scientists invent threads to detect gases when woven into clothing

Scientists have developed a novel fabrication method to create dyed threads that change color when they detect a variety of gases. Woven into clothing, smart, gas-detecting threads could provide a reusable, washable, and affordable safety asset in medical, workplace, military and rescue environments. The study describes the fabrication method and its ability to extend to a wide range of dyes and detection of complex gas mixtures.

Just 20 minutes of contact with nature will lower stress hormone levels, reveals new study

Taking at least 20 minutes out of your day to stroll or sit in a place that makes you feel in contact with nature will significantly lower your stress hormone levels. That's the finding of a study that has established for the first time the most effective dose of an urban nature experience. Healthcare practitioners can use this discovery to prescribe 'nature-pills' in the knowledge that they have a real measurable effect.

Scientists discover first organism with chlorophyll genes that doesn't photosynthesize

For the first time scientists have found an organism that can produce chlorophyll but does not engage in photosynthesis. The peculiar organism is dubbed 'corallicolid' because it is found in 70 per cent of corals around the world and may provide clues as to how to protect coral reefs in the future.

The brain's auto-complete function

When looking at a picture of a sunny day at the beach, we can almost smell the scent of sun screen. Our brain often completes memories and automatically brings back to mind the different elements of the original experience. A new study now reveals the underlying mechanisms of this auto-complete function.

A 5,000-year-old barley grain discovered in Finland changes understanding of livelihoods

A 5,000-year-old barley grain discovered in Aland, southern Finland, turns researchers' understanding of ancient Northern livelihoods upside down. New findings reveal that hunter-gatherers took to farming already 5,000 years ago in eastern Sweden, and on the Aland Islands, located on the southwest coast of Finland.
