Japan has developed a smoke detector for deaf people that is based on the pungent smell of Japan’s spicy green horseradish, an eye-watering condiment more typically found tucked under fish in a piece of sushi.
If it detects smoke, the alarm sprays out a synthesized wasabi smell that wakes up people who might have slept through a conventional fire alarm.
Assistant professor Makoto Imai from the Shiga University of Medical Science, who built the alarm in collaboration with Seems, a company that makes perfume, says the smoke detector may save lives among the hard of hearing.
He said the Wasabi smoke detector was tested on 14 people, including four deaf people.
Imai said trial production of the Wasabi smoke detector would be completed in a year and the product would be sold in shops within two years.
Google parent Alphabet borrowed $10 billion via its biggest — and cheapest — corporate bond sale ever on Monday.
The company pledged to use $4.5 billion for corporate moves, like acquisitions, and funnel the other $5.5 billion into environmental and social initiatives.
Alphabet also issued the bonds with some of the lowest interest rates in corporate history.
Alphabet‘s 10-year bond raised $2.25 billion, sold with a yield of 1.1%, while its five-year tranche promised buyers 0.45% interest.
The motivation behind Alphabet‘s bond sale, its first in four years, remains unclear — especially considering the Mountain View tech giant currently sits on $121 billion in cash and short-term investments.
Ultimately, Alphabet must’ve considered the costs of the debt simply too cheap to pass up.
