Breakthrough technology keeps you warm in the winter, and cool in the summer, without consuming natural gas or electricity. Scientists have developed an all-season smart-roof coating that keeps homes warm during the winter and cool during the summer – without consuming natural gas or electricity. Research findings reported in the Dec. 17 edition of the journal Science point to a groundbreaking technology that outperforms commercial cool-roof systems in energy savings. “Our all-season roof coating automatically switches from keeping you cool…
An international research team led by scientists from Nanyang Technological University, Singapore (NTU Singapore) has developed a material that, when coated on a glass window panel, can effectively self-adapt to heat or cool rooms across different climate zones in the world, helping to cut energy usage. Developed by NTU researchers and reported in the top scientific journal Science, the first-of-its-kind glass automatically responds to changing temperatures by switching between heating and cooling. The self-adaptive glass is developed using layers of…
New method enables simple tritium labeling and could provide added value to the discovery and development of pharmaceuticals. The new tritiation reaction is practical and robust to execute and could have an immediate impact in the discovery and development of pharmaceuticals. Tritium 3H, a radioactive isotope of hydrogen, is commonly used in medicinal chemistry as a label to follow the course of a drug in the human body. Chemists like to use the technique to evaluate drug candidates and their…
The respiratory chain plays a central role in energy metabolism of the cell. It is localized in mitochondria, the cell´s own power plants. In a new study, researchers from Goethe University, the Max Planck Institute of Biophysics and the University of Helsinki have determined the high-resolution structure of a central component of the respiratory chain, mitochondrial complex I, and simulated its dynamics on the computer. These findings both support basic research and enhance our understanding of certain neuromuscular and neurodegenerative…
With their altered metabolism, cancer cells grow faster than normal cells. Scientists at Leipzig University’s Faculty of Medicine have now discovered that cancer cells need the succinate receptor to control their metabolic rate. This knowledge should in future help doctors to develop treatments. Cancer cells show unchecked rapid growth beyond tissue boundaries that is no longer stopped by normal control mechanisms. Due to this rapid growth, the metabolism of cancer cells is altered compared to that of cells that grow…
Scientists at the Fraunhofer Institute for Organic Electronics, Electron Beam and Plasma Technology FEP have succeeded in realizing a multicolor OLED microdisplay that consumes the lowest power of all available microdisplays with an extended range of applications compared to monochrome displays. This OLED microdisplay was realized within the “Backplane” project funded by the Saxon State Ministry of Economic Affairs, Labour and Transport (SMWA, funding reference: 100392259). It will be presented at CES, January 05 – 08, 2022, in Las Vegas/USA,…
Our brains can distinguish highly similar patterns, thanks to a process called pattern separation. How exactly our brains separate patterns is, however, not fully understood yet. Using a full-scale computer model of the dentate gyrus, a brain region involved in pattern separation, Peter Jonas, Professor at the Institute of Science and Technology (IST) Austria, found that inhibitory neurons activated by one pattern suppress all their neighboring neurons, thereby switching off “competing” similar patterns. This is the result of a study…
“Until now researchers have encoded and stabilized. We now show that we can compute as well.” Researchers at QuTech—a collaboration between the TU Delft and TNO—have reached a milestone in quantum error correction. They have integrated high-fidelity operations on encoded quantum data with a scalable scheme for repeated data stabilization. The researchers report their findings in the December issue of Nature Physics. More qubits Physical quantum bits, or qubits, are vulnerable to errors. These errors arise from various sources, including…
Model replicates features of complex disease, provides platform for screening existing drugs. Using a stem-cell-derived model, researchers have identified two drug candidates that may slow dry age-related macular degeneration (AMD), a leading cause of blindness for which no treatment exists. The scientists, from the National Eye Institute (NEI), part of the National Institutes of Health, published their findings today in Nature Communications. “This stem-cell-derived model of dry AMD is a game-changer. Scientists have struggled to unravel this incredibly complex disease,…
A nanocomposite that absorbs X-rays and then, with nearly perfect efficiency, re-emits the captured energy as light, could help to improve high-resolution medical imaging and security screening. The material’s near-100 percent energy transfer could bring efficiency gains in devices ranging from light-emitting diodes (LEDs) and X-ray imaging scintillators, all the way to solar cells1. During a medical imaging procedure, X-rays passing through the body are absorbed by a scintillator material, which converts X-rays into light for a digital camera type…
European forest condition monitor… The increasing frequency of extreme weather conditions due to climate change poses a threat to forests worldwide. Droughts, late frosts, water-logged soils after floods, heavy precipitation and winter storms often cause tree die-back. Since extreme environmental conditions often impair tree defense mechanisms, secondary pathogens such as fungi and beetles frequently amplify tree decline and die-back rates. Some tree mortality factors are easier to track in live “Tree health is impacted by soil conditions, the stand structure…
Many of the per- and polyfluoroalkyl substances (PFAS) that end up in the ocean boomerang back to shore after they are re-emitted into air with the crashing of waves, according to a study by researchers at Stockholm University published today in Environmental Science & Technology. The findings suggest that this sea-to-air transport process is a significant contributor to PFAS air pollution in coastal areas. “The common belief was that PFAS would eventually wash off into the oceans where they would stay…
New study shows: Tropical seagrass meadows absorb in some cases significantly less carbon dioxide than long thought. To avert the worst consequences of climate change, humanity needs to considerably reduce the amount carbon dioxide (CO2), a greenhouse gas, in the atmosphere over the coming years. To this end, a common suggestion is to restore natural CO2 reservoirs on the coasts that have been destroyed in many locations during the past decades. This includes mangrove forests, salt marshes and what are…

Importantly this discovery has opened up the possibility of drugs to promote this enzyme’s activity, protecting against the consequences of aging. Monash University, Australia scientists have discovered an enzyme that is key to why exercise improves our health. Importantly this discovery has opened up the possibility of drugs to promote this enzyme’s activity, protecting against the consequences of ageing on metabolic health, including type 2 diabetes….
Physicists construct theories to describe nature. Let us explain it through an analogy with something that we can do in our everyday life, like going on a hike in the mountains. To avoid getting lost, we generally use a map. The map is a representation of the mountain, with its houses, rivers, paths, etc. By using it, it is rather easy to find our way to the top of the mountain. But the map is not the mountain. The map…
