Efficient and cheap batteries that can also capture harmful emissions could be right around the corner, thanks to a new system that speeds up the development of catalysts for lithium-CO2 (Li-CO2) batteries. The technology has been developed by the University of Surrey, Imperial College London, and Peking University to address…
29, 30, 32… — these are not random numbers, but the efficiency of solar cells, measured by the percentage of incidental sunlight they convert into electrical power. The ellipsis at the end of the line is also not a coincidence, as the efficiency of tandem solar cells has already exceeded…
Birds native to the tropical Andes, many of which cannot be found anywhere else, are threatened by increasing agricultural development in the region. A new study details how the resulting habitat loss affects specific species and lays out possible ways to protect birds from human-driven disturbance. The researchers combined a…
Proteins consist of amino acids, which are linked to form long amino acid chains as specified by our genetic material. In our cells, these chains are not simply rolled up like strings of pearls, but fold into complex, three-dimensional structures. How a protein is folded decisively influences its function: It…
Train elementary school students how to be creative and you can help increase their resilience in the face of real-life problems, new research suggests. In a small study, researchers trained third, fourth and fifth graders to use literary techniques such as perspective shifting, counter-factual (what if) thinking and causal (why)…
A shipping container that can test passive cooling systems could help researchers and builders find carbon-free ways to keep people cool in extreme temperatures. Washington State University researchers created the 60 square-foot chamber to test passive systems that use wind towers along with water evaporation instead of electricity to cool…
Structural formulae show how chemical compounds are constructed, i.e., which atoms they consist of, how these are arranged spatially and how they are connected. Chemists can deduce from a structural formula, among other things, which molecules can react with each other and which cannot, how complex compounds can be synthesised…
Humans aren’t the only ones leaving town when city heat becomes unbearable. A study done on 336 cities in China concludes that heat-retaining buildings and paved surfaces are directly related to a loss in bird diversity. These findings from scientists at Zhejiang University and the Cornell Lab of Ornithology are…
Tidal flats, also known as mud flats, make up coastal wetlands that protect against destructive powers from the ocean such as waves, tsunamis and hurricanes. These guardians of the coastlines, however, are under threat due to natural and human events. Climate change including sea level rise and rapid urbanization have…
A team of University of Minnesota Medical School researchers successfully tested a new antifungal therapy to treat fungal meningitis. The trial results were published today in the peer-reviewed journal Clinical Infectious Diseases. The research team tested a new oral formulation of the antifungal medication amphotericin among people who had HIV…
Engineers in Australia have found a way of making stronger concrete with roasted used-coffee grounds, to give the drink-additive a “double shot” at life and reduce waste going to landfills. Lead author Dr Rajeev Roychand from RMIT University said the team developed a technique to make concrete 30% stronger by…
In the context of accelerating rates of global biodiversity loss, tracking changes in wildlife is instrumental to inform adaptive management strategies and conserve biodiversity. At the same time, the majority of emerging infectious diseases have their origins in wild animal populations. Thus, understanding which animal species are where is an…
Millions of people around the world experience some form of hearing loss, resulting in negative impacts to their health and quality of life. Treatments exist in the form of hearing aids and cochlear implants, but these assistive devices cannot replace the full functionality of human hearing and remain inaccessible for…
