Scientists design hearing aid that uses just $1 worth of parts
200 million adults over the age of 65 suffer from age-related hearing loss around the world. In response, scientists at the Georgia Institute of Technology have designed a hearing aid device that uses only a dollar’s worth of open-source parts and a 3D-printed case to function. The Read More...
Adding floating solar to hydropower plants would create an energy boom
A new study suggests there is a way to make hydropower plants produce more energy: placing floating solar panels on the reservoirs of hydropower plants. According to a new analysis of the energy potential of combining these facilities with floating solar panels, scientists calculated that these Read More...
A step-by-step guide for repotting your houseplants
During the lockdown, you took the opportunity to spruce up your living space with a new houseplant. You tended to it, gave it care, and over time it’s grown quite big. But there comes a point when your plant becomes too big for its own pot, and if you leave it in there too long, it will suffer. Read More...
Drone successfully completes longest organ delivery via unmanned aircraft
From creating breathtaking light shows to helping restore degrading ecosystems to delivering books to kids, drones can do an awful lot of things these days — including the life-saving task of transporting human organs for transplant. That is what a team of researchers from MissionGO, a provider Read More...
How quantum computing can boost energy grid resilience
Renewable energy is the power source of the future, but building reliable grids to transport this energy is no simple task. This is why GreenBiz author and engineering professor Amin Khodaei believes quantum computing is the solution to building dependable grids for a sustainable energy Read More...
Hydrogen-powered commercial aircraft successfully completes maiden flight
Over the last few years, hydrogen has been gaining serious traction for its potential to replace jet fuel and propel the aviation industry towards a zero-emissions future. More recently, aerospace giant Airbus announced its ZeroE initiative to manufacture hydrogen-powered commercial planes by 2035. Read More...
Jet suits could soon help paramedics reach remote areas in no time
If you’ve ever wondered what the future of remote medicine may look like, it’s probably safe to say that it will involve jet packs. At least, that’s what a groundbreaking exercise run by an air ambulance service in England has recently demonstrated in one of the country’s mountainous Read More...
3D bioprinting could be the future of non-invasive surgery
3D printing has been used to make jewelry, prosthetics, and even entire homes. Now, scientists are looking to 3D printing to repair living tissue within the human body. If successful, the technology could be used to treat ulcers and other gastrointestinal wounds which affect one in eight people Read More...
New super-enzyme eats plastic six times faster than previous one
Certain types of bacteria naturally break down plastic. Harnessing the power of these special bacteria, scientists have created a “super enzyme” that can degrade plastic bottles. And it’s doing it at a rate six times faster than previously projected. The enzyme was created by connecting Read More...
Telecommuting can slash emissions. Should it be required?
Working from home has become the norm in the San Francisco Bay Area, leading to a sizable drop in greenhouse gas emissions. Because of this, the Bay Area’s Metropolitan Transportation Commission has voted to move forward with a proposal to require people at large, office-based companies to work Read More...
