Chiral molecular self-assemblies that absorb light boost singlet fission process, research demonstrates
In organic molecules, an exciton is a particle bound pair of an electron (negative charge) and its hole (positive charge). They are held together by Coulombic attraction and can move within molecular assemblies. Singlet fission (SF) is a process wher.....»»
Scientists investigate contrail formation to reduce climate impact
From the development of new materials that make airplanes lighter to the exploration of alternative fuels, the aviation industry is making strides toward reducing its carbon footprint......»»
Variations in scientific ethics: Chinese scientists prioritize government service more than global peers
In a new study of physicists from the U.S., U.K. and China, Rice University and Santa Clara University researchers found that Chinese scientists feel a greater obligation to serve their government with research efforts than international counterparts.....»»
Charcoal stored in preserved guano gives helps reconstruct regional fire histories
With wildfires growing more frequent and more intense in many parts of the world, scientists are looking to the past to better understand where and when fires have burned. Lakes and wetlands, which capture airborne charcoal particles when they fall f.....»»
Study reveals superbug MRSA"s double defense against antibiotics
Scientists have discovered the mechanism which allows the superbug methicillin resistant Staphylococcus aureus (MRSA) to become highly resistant to antibiotics, paving the way for new approaches to control infectious disease......»»
Scientists witness stunning, unprecedented carnage in the ocean
Scientists observed the largest-ever predatory event in the ocean when a mass of Atlantic cod consumed over 10 million capelin in the Barents Sea off of Norway. On an unassuming morning off the Norwegian coast, millions of small fish called cap.....»»
Simple science summaries written by AI can help people understand research and trust scientists
Artificial intelligence-generated summaries of scientific papers make complex information more understandable for the public compared with human-written summaries, according to my recent paper published in PNAS Nexus. AI-generated summaries not only.....»»
AI method captures ecotourism photos to monitor remote animal species
A team of computer scientists, ecologists and statisticians at Stony Brook University, working with a colleague from the U.S. Geological Survey, has found that it is possible to use AI applications to find images captured by ecotourists for use in st.....»»
Machine-learning analysis tracks the evolution of 16th-century European astronomical thought
A team of computer scientists, astronomers and historians in Berlin has used machine-learning applications to learn more about the evolutionary history of European astronomical thought in the 15th and 16th centuries. In their study published in the j.....»»
Scientists develop starch nanocomposite films that pave the way for green electronics
Queen Mary University of London researchers have developed new nanocomposite films using starch instead of petroleum-based materials, marking a significant advancement in the field of sustainable electronics......»»
Research shows decline in out-of-home activities since pandemic
Compared with just before the COVID-19 pandemic, people are spending nearly an hour less a day doing activities outside the home, behavior that researchers say is a lasting consequence of the pandemic......»»
NASA and NOAA rank 2024 ozone hole as 7th-smallest since recovery began
Healing continues in the atmosphere over the Antarctic: a hole that opens annually in the ozone layer over Earth's southern pole was relatively small in 2024 compared to other years. Scientists with NASA and the National Oceanic and Atmospheric Admin.....»»
Quantum simulator could help uncover materials for high-performance electronics
Quantum computers hold the promise to emulate complex materials, helping researchers better understand the physical properties that arise from interacting atoms and electrons. This may one day lead to the discovery or design of better semiconductors,.....»»
Australian courts use "body language" to judge witness credibility
Nonverbal behavior in the courtroom can significantly influence how judges assess the credibility of witnesses in their rulings. But is reliance on "body language" based on sound science?.....»»
This ancient tadpole fossil is the oldest ever discovered
Scientists have discovered the oldest-known fossil of a giant tadpole that wriggled around over 160 million years ago......»»
Scientists describe how mycobacteria evade the effects of antibiotics
One of the main challenges of contemporary medicine is posed by the resistance of pathogens to antibiotics. An important step in countering it has now been made by researchers from IOCB Prague, in collaboration with colleagues from the Institute of M.....»»
AI training method can drastically shorten time for calculations in quantum mechanics
The close relationship between AI and highly complicated scientific computing can be seen in the fact that both the 2024 Nobel Prizes in Physics and Chemistry were awarded to scientists for devising AI for their respective fields of study. KAIST rese.....»»
Study models dinoflagellate light in breaking waves
A new study led by Scripps Institution of Oceanography demonstrates, for the first time, how scientists can use computer simulations to quantify the light emitted by dinoflagellates when they flash in breaking waves and create stunning displays of bi.....»»
