Researchers have used carbon dots, created from human hair waste sourced from a barbershop, to create a kind of ‘armor’ to improve the performance of cutting-edge solar technology. In a study,Â the researchers led by Professor Hongxia Wang in collaboration with Associate Professor Prashant Sonar of QUT’s Centre for Materials Science showed the carbon nanodots could […]

(Texas A&M University) The introduction of lithium-ion (Li-ion) batteries has revolutionized technology as a whole, leading to major advances in consumer goods across nearly all sectors. Battery-powered devices have become ubiquitous across the world. While the availability of technology is generally a good thing, the rapid growth has led directly to several key ethical and environmental issues surrounding the use of Li-ion batteries.
Researchers in Finland have discovered that electrodes in lithium batteries containing cobalt can be reused following a special process. In comparison to traditional recycling, which typically extracts metals from crushed batteries by melting or dissolving them, the new processâwhich newly saturates the electrodes with lithiumâsaves valuable raw materials, and likely also energy. The rechargeable batteries […]

Watch NASA Mars Helicopter Make Aviation History: The First Powered, Controlled Flight on Another Planet
When NASA’s Perseverance rover touched down on Mars two months ago, it did so with a helicopter attached to its belly. Now the Ingenuity Mars Helicopter has made history as the first to take a powered, controlled flight on another planet. On April 19, the chopper rose three meters above the floor of a crater, […]
(Wildlife Conservation Society) A powerful, long-term study from WCS adds scientific backing for global calls for conserving 30 percent of the world’s ocean.
A professional yacht racer, annoyed by the constant sightings of floating mats of plastic garbage in coastal waters, has designed an ocean-cleaning sailboat that is powered by the waste it collects. The 56-meter (184 feet) Manta is the first offering from racer Yves Bourgnon’s SeaCleaners Project, and would be one of the largest waste-collecting vessels […]

Unilever has partnered with LanzaTech and India Glycols to produce a laundry soap made from industrial carbon emissions—instead of from fossil-fuels. The innovative shift in production utilizes biotechnologies and a newly configured supply chain between the three partners, who are working together for the first time. Typically derived from fossil fuels, surfactants are a critical […]

Researchers Create CRISPR ‘On-Off Switch’ to Control Inherited Genetic Problems Without Changing DNA
Scientists have figured out how to modify the unrivaled gene-editing tool CRISPR to extend its reach to the epigenome, which controls how genes are switched on or off. The researchers from the University of California, San Francisco, and MITâs non-profit Whitehead Institute for Biomedical Research and have already used the tool in the lab to […]
Tiny molecules called nanobodies, which can be designed to mimic antibody structures and functions, may be the key to blocking a tick-borne bacterial infection that remains out of reach of almost all antibiotics, new research suggests. The infection is called human monocytic ehrlichiosis (HME), and is one of the most prevalent and potentially life-threatening tick-borne […]

Microbiologists have found a way to use bacteria to trap microplastics, removing them from the environment and making them easier to recycle. The new technique, developed by scientists at Hong Kong Polytechnic University, uses bacterial biofilmsâa sticky substance created by micro-organismsâto trap microplastic particles. The biofilm is then processed and dispersed, releasing the microplastic particles […]
