Planting the seeds for better vertical farm crops

Good News Notes: “Humans have been farming outside for around 12,000 years. Over those thousands of years, farmers have stumbled upon or bred specific varieties of plants and seeds that do well in outdoor field farming environments. And as farming has turned from a local business to a massive profit-making behemoth, the process of developing the…

Can This Sun-Reflecting Fabric Help Fight Climate Change?

Good News Notes: “IN 2020, A graduate student from Zhejiang University in China donned a seemingly plain white vest and sat in the direct sunlight for one hour. A few feet away, researchers monitored his body temperature with infrared cameras and sensors on his skin. Half of the vest was made from ordinary cotton; the other…

Alternative cement with low carbon footprint developed

Good News Notes: “Researchers at the Martin Luther University Halle-Wittenberg (MLU) in Germany and the Brazilian University of Pará have developed a climate-friendly alternative to conventional cement. Carbon dioxide (CO2) emissions can be reduced during production by up to two thirds when a previously unused overburden from bauxite mining is used as a raw material….

Microorganisms Used to Convert CO2 into Plastic and Polymers

Good News Notes: “They employed greenhouse gas as a raw material for producing plastics. To perform this, they initially produced formic acid and methanol from CO2, which were later converted into building blocks for polymers and similar materials through microorganisms. When fossil-based raw materials are burned, CO2 is emitted into the atmosphere. Until now, CO2 concentration in…

Purdue University develops new way to recycle polyolefin plastics

Good News Notes: “Single-use plastic scrap continues to be a growing problem internationally with only 9 percent of the 8.3 billion tons of plastic produced in the last 65 years being recycled. One of the biggest contributors to this issue is polyolefins, such as polypropylene and polyethylene. Researchers at Purdue University are working to solve that problem…

Solar device generates electricity and desalinates water with no waste brine

Good News Notes: “A device that can generate electricity while desalinating seawater has been developed by researchers in Saudi Arabia and China, who claim that their new system is highly efficient at performing both tasks. The device uses waste heat from the solar cell for desalination, thereby cooling the solar cell. It also produces no…

Waste hop stem in the beer industry upcycled into cellulose nanofibers

Good News Notes: “Some three quarters of the biomass in hop plants used in beer-making ends up in landfills. But a group of Japanese researchers has developed a technique that ‘upcycles’ that waste hop into cellulose nanofibers (CNFs). A paper describing the technique was published in the journal ACS Agricultural Science & Technology on June 11. In…

New prehistoric human unknown to science discovered in Israel

Good News Notes: “A new type of early human previously not known to scientists has been discovered in Israel, Tel Aviv University and Hebrew University researchers announced Thursday as their extraordinary findings appeared in the prestigious academic journal Science. Researchers believe the new “Homo” species intermarried with  Homo sapiens and was an ancestor of the…
