Message scent: oPhone sends smells as a text or email

The smartphone has certainly ushered in a state of hyper-connectivity, where the sharing of information over long distances, even to the other side of the world, is a simple tweet, email or Snapchat away. While these platforms offer up plenty of content for our eyes and ears, some feel that our noses are missing out on all the fun and have developed the oPhone, a Bluetooth-enabled odor emitting device designed to enable users to send smells to one another as a text or email.

The Scent Rhythm watch tells time by releasing fragrances

Glancing at a clock face in one form or another has been the de facto way to measure the passage of time. Aisen Caro Chacin though, is exploring a different perspective. She wants to give everyone the ability to tell time using their noses. Her chemical-based watch called the Scent Rhythm emits specially-designed fragrances in minute doses, in tune with circadian cycle of the human body. You get a fragrance of coffee in the morning, the smell of money in the afternoon, a relaxing whiskey scent in the evening, and a soothing chamomile fragrance at night. More than being merely pleasant, each chemically-supplemented scent aims to induce action appropriate to the time of day; the caffeine in the coffee scent, for example, aims to trigger the person into being more active.

Madeleine "smell camera" records odors for the future

The five traditional senses of perception – sound, sight, smell, touch, and taste – are all capable of triggering memories. However, we haven't yet figured out how to capture copies of all of these inputs. We can capture images on cameras and sounds on audio equipment, we can recreate tastes to a certain degree, and we can simulate touch with physical copies of other things. But what about smells? The ability to capture everyday odors in an immutable state has eluded us. Until now. Read More

Rac-Em-Bac puts a bullet in your bow

Many archers in adventure stories and comic books use arrows with unusual heads. These include the standard explosive and grappling hook arrows, and the not-so-standard boxing glove arrow, Greek fire arrow, handcuffs arrow, and the ever popular atomic warhead arrow. While real archers generally have to make do with target and field heads, Louisiana-based archery company Rac-Em-Bac is now providing some spirited alternates. Read More

Moth takes the driver's seat in smell-tracking robot

In the future, we may have autonomous robots that follow scents to track down gas leaks, rescue disaster victims trapped in debris, or perform other duties. While the algorithms that drive such robots could perhaps just be made up from scratch, scientists from the University of Tokyo are instead looking to the insect world for inspiration. To that end, they recently created a two-wheeled robot that was successfully driven by female-seeking male silkmoths. Read More

Scientists block insects' sense of smell to protect crops

Good news for crop farmers this week with UK scientists discovering molecules they hope will confuse insects’ sense of smell and therefore their ability to detect plants – and each other. The researchers believe this could reduce the damage insects cause to crops and lead to better food security. Roughly one-quarter of the world’s crops are lost annually to pests and disease. Read More
