An international team led by researchers at UCL has revealed new insights into the workings of a lithium battery by virtually "unrolling" its coil of electrode layers using an algorithm designed for papyrus scrolls.
When Dan Lopresti and his colleagues talk about the future of artificial intelligence (AI) during their upcoming panel at the annual meeting of the American Association for the Advancement of Science (AAAS), be prepared to imagine a better world.
Recent outbreaks of the novel coronavirus have emphasized the importance of quarantine and prevention more than ever. When monitoring changes in our body, body temperature is first measured. So, it is very significant to measure the temperature accurately and promptly. With this regard, a research team recently developed a stretchable and crumpling polymer ionic conductor to realize a thermal sensor that could measure body temperature by simple contacts such as wearing clothes or shaking hands and an actuator that could control movements of artificial muscle.
Although stopping climate change is challenging, it is imperative to slow it down as soon as possible by reducing greenhouse gas emissions. But how can we meet the growing energy demand while reducing our use of polluting fossil fuels? Geothermal energy is an efficient, non-polluting solution but in certain cases geothermal operations must be handled with care. Reaching the most powerful sources of available energy means drilling deep into the layers of the earth's crust to find geothermal fluids with high energy content (hot water and gas released by magma).
Adding sewage sludge on soils does not promote antibiotic resistance, a study from University of Gothenburg shows.
Some of the antibiotics we use end up in sewage sludge, together with a variety of antibiotic resistant bacteria present in feces. Therefore, there is a widespread concern that spreading sludge on farmland would contribute to the development or spread of antibiotic resistance.
Kanazawa, Japan - The need to efficiently harvest solar energy for a more sustainable future is increasingly becoming accepted across the globe. A new family of solar cells based on perovskites--materials with a particular crystal structure--is now competing with conventional silicon materials to satisfy the demand in this area.
The high field magnet at HZB generates a constant magnetic field of up to 26 Tesla. This is about 500,000 times stronger than the Earth's magnetic field. Further experiments with pulsed magnetic fields up to 45 Tesla were performed at the Helmholtz-Zentrum Dresden-Rossendorf (HZDR).
Reaching room-temperature superconductivity is one of the biggest dreams in physics. Its discovery would bring a technological revolution by providing electrical transport with no loss, ultra efficient electrical engines or generators, as well as the possibility of creating huge magnetic fields without cooling. The recent discoveries of superconductivity first at 200 kelvin in hydrogen sulfide and later at 250 kelvin in LaH10 have spurred attention to these materials, bringing hopes for reaching room temperatures soon.
Too many patients with cancers like multiple myeloma relapse after treatment. This grim reality motivated researchers at Huntsman Cancer Institute (HCI) at the University of Utah (U of U) to try to improve the depth and durability of treatment response in multiple myeloma through a new cancer cell targeting mechanism. Multiple myeloma is the second most common blood cancer and develops in the bone marrow. Approximately 30,000 new cases are diagnosed each year, and almost all patients eventually succumb to their disease.
Scientists have identified a key molecule involved in the development of cerebral malaria, a deadly form of the tropical disease. The study identifies a potential drug target and way forward toward alleviating this condition for which few targeted treatments are available.
When NASA's Aqua satellite passed over the Southern Indian Ocean on Feb. 7, it gathered water vapor data that provided information about the intensity of Tropical Cyclone Damien.
An interdisciplinary team of researchers at Colorado State University has used computational chemistry, biochemistry and virology to uncover new information on how viruses such as West Nile, dengue and Zika replicate. Based on their research, the team said these viruses appear to cripple their own genome replication machinery.
CSU researchers described the results as "surprising," and said the findings have implications for future vaccine and antiviral drug development.
ATLANTA--A new method to detect cancer in its early stages using a targeted MRI contrast agent that binds to proteins has been identified by a team of researchers led by Georgia State University Regents' Professor Jenny Yang.
A group of St. Petersburg scientists has proposed and experimentally tested a technology for the fabrication of high-efficiency solar cells based on A3B5 semiconductors integrated on a silicon substrate, which in the future may increase the efficiency of the existing single-junction photovoltaic converters by 1.5 times. The development of the technology was forecasted by the Nobel Laureate Zhores Alferov. The results have been published in the journal Solar Energy Materials and Solar Cells.
An international research team have for the first time observed dynamic covalent oligomers mimicking the combination of complementary DNA strands, which could lead to exciting developments in electronics and the engineering of interfaces between prostheses and body tissue.
