Chemists Find Breakthrough Treatment for Alzheimer’s and Parkinson’s That Protects Brain Cells From Amyloid Plaque

Alzheimer’s and Parkinson’s are diseases of the brain in which gradual degeneration of neurons leads to loss of speech, memory, and thinking. Existing remedies are aimed only at suppressing symptoms, but cannot stop the process of neurodegeneration itself. Now Russian scientists have synthesized chemical compounds that can stop the degeneration of neurons in Alzheimer’s, Parkinson’s, […]

The hidden culprit killing lithium-metal batteries from the inside

(DOE/Sandia National Laboratories) The first nanoscale images ever taken inside intact, lithium-metal coin batteries (also called button cells or watch batteries) challenge prevailing theories and could help make future high-performance batteries, such as for electric vehicles, safer, more powerful and longer lasting.

NASA space lasers map meltwater lakes in Antarctica with striking precision

(NASA/Goddard Space Flight Center) From above, the Antarctic Ice Sheet might look like a calm, perpetual ice blanket that has covered Antarctica for millions of years. But the ice sheet can be thousands of meters deep at its thickest, and it hides hundreds of meltwater lakes where its base meets the continent’s bedrock. Deep below the surface, some of these lakes fill and drain continuously through a system of waterways that eventually drain into the ocean.

New clues to why there’s so little antimatter in the universe

(Massachusetts Institute of Technology) An MIT study shows radioactive molecules are sensitive to subtle nuclear phenomena. The molecules might help physicists probe violation of the most fundamental symmetries of nature, including why the universe contains relatively little antimatter.

Large measurement campaign in the Atlantic starts

(Leibniz Institute for Tropospheric Research (TROPOS)) To support the novel ESA wind satellite ‘Aeolus,’ TROPOS has now installed a lidar in Mindelo, Cabo Verde. The light radar uses lasers to study the atmosphere in the tropical Atlantic and is part of the ‘Aeolus Tropical Campaign,’ which will take place in summer and autumn 2021 and will also contribute to the research on clouds and aerosols in the tropics and to better understand the formation of tropical cyclones (hurricanes).

Pushing the boundaries of colloidal quantum dots by making their sizes equal

(DGIST (Daegu Gyeongbuk Institute of Science and Technology)) Perovskite colloidal quantum dots (Pe-CQDs) are highly promising nanocrystals for optoelectronic applications. However, the size of the crystals should ideally be equal to ensure a consistent energy landscape. In a recent study, scientists clarified the relationship between differences in particle size — polydispersity — and the optoelectronic characteristics of Pe-CQDs. They showed that using equally sized, or ‘monodisperse,’ quantum dots results in markedly better performance in Pe-CQD solar cells, paving the way for future optoelectronic devices.

Farmers Now Use Floating Gardens To Keep Crops Alive When it Floods — A Climate Crisis Lesson

Bangladesh’s floating gardens, built to grow food during flood seasons, could offer a sustainable solution for parts of the world prone to flooding because of climate change, a new study has found. The study suggests that floating gardens might not only help reduce food insecurity, but could also provide income for rural households in flood-prone parts […]

See the Strange, Beautiful Landscapes Below the Foliage and Buildings Revealed by Lasers

Staggering images taken from planes using forest-penetrating radar are mapping the geology of Washington state. Intriguing, artsy, beautiful, and outright bizarre, “The Bare Earth” presentation on the Washington state Department of Natural Resources (DNR) website uses shading and added color to present underlying geological features like lava flows, glacial moraines, drumlins, tsunami inundation, mudslides, eruptions, […]

Atom swapping could lead to ultra-bright, flexible next generation LEDs

(University of Cambridge) An international group of researchers has developed a new technique that could be used to make more efficient low-cost light-emitting materials which are flexible and can be printed using ink-jet techniques.
