Bifunctional acid−base catalysts are highly desirable for industrially relevant chemical processes. Owing to their ability to activate electrophiles and nucleophiles simultaneously, they allow the catalysis to proceed synergistically and cooperatively. Solid acid−base catalysts are particularly advantageous since they are reusable and result in no waste products. However, controlling the structure of such catalysts for cooperatively workable active sites is challenging. Simple and effective methods that enable the synthesis of high-performance solid acid−base ...

An international team of researchers from Leibniz University Hannover (Germany), the University of Twente (Netherlands), and the start-up company QuiX Quantum has presented an entangled quantum light source fully integrated for the first time on a chip. “Our breakthrough allowed us to shrink the source size by a factor of more than 1000, allowing reproducibility, stability over a longer time, scaling, and potentially mass-production. All these characteristics are required for real-world applications such as quantum processors,” says Prof. Dr. Michael Kues, head of the Institute ...

Researchers from Tokyo Medical and Dental University (TMDU) find that, when a stroke therapy is linked to a specific kind of lipid and injected into the blood, it is taken up preferentially in the stroke-lesioned brain   Tokyo, Japan – To get therapies into the brain after a stroke, researchers are increasingly making use of the blood–brain barrier, which allows only certain molecules to pass from the blood into the brain. In a study published earlier this year in Molecular Therapy, ...

BEER-SHEVA, Israel, April 17, 2023 – Scientific research must meet clear ethical guidelines to prevent harm to participants. However, research can also indirectly harm individuals and social groups, for example by shaping social perceptions and inspiring policy. Researchers receive little to no training on how to consider and minimize such harm. To that end, Ben-Gurion University of the Negev's Dr. Niv Reggev and his international colleagues have published ten simple rules for socially responsible science. The ...

In parts of California’s iconic mountainous coasts, breathtaking beauty is punctuated by brusque signs warning spectators to stay back from unstable cliffs. The dangers of coastal erosion are an all-too-familiar reality for the modern residents of these communities. Now, with a new tool, researchers are bringing historical perspective to the hotly debated topic of how to manage these disappearing coastlines. Using a model that incorporates measurements of the amount of time coastal cliffs and their remnant deposits were exposed at the Earth’s surface, Stanford researchers found that the rate of cliff erosion in the past 100 years is ...

People living with long Covid who suffer from loss of smell show different patterns of activity in certain regions of the brain, a new study led by UCL researchers has found. The research used MRI scanning to compare the brain activity of people with long Covid who lost their sense of smell, those whose smell had returned to normal after Covid infection, and people who had never tested positive for Covid-19. Published in eClinicalMedicine, the observational study found that the people with long Covid smell loss had reduced brain activity and impaired communication between two parts of the brain which process ...

A parabolic dish on the EPFL campus is easily overlooked, resembling a satellite dish or other telecommunications infrastructure. But this dish is special, because it works like an artificial tree. After concentrating solar radiation nearly 1,000 times, a reactor above the dish uses that sunlight to convert water into valuable and renewable hydrogen, oxygen, and heat. “This is the first system-level demonstration of solar hydrogen generation. Unlike typical lab-scale demonstrations, it includes all auxiliary devices and components, so it gives us a better idea of the energy efficiency you can expect ...

Using a new detection method, UC Riverside scientists found a massive amount of methane, a super-potent greenhouse gas, coming from wildfires — a source not currently being accounted for by state air quality managers. Methane warms the planet 86 times more powerfully than carbon dioxide over the course of 20 years, and it will be difficult for the state to reach its required cleaner air and climate goals without accounting for this source, the researchers said.  Wildfires emitting methane ...

McMaster University researchers have developed a rapid and inexpensive test for Salmonella contamination in chicken and other food – one that’s easier to use than a home COVID test. The test, described in a new paper in the journal Angewandte Chemie, could improve food safety, reduce the cost of processing fresh poultry and other foods, and help to limit broad recalls to batches that have specifically been identified as contaminated. The researchers have shown that the test provides accurate results in an hour or less without the need for accessories or a power source, compared ...

PULLMAN, Wash. – Discovery of a gene in multiple mammalian species could pave the way for a highly effective, reversible and non-hormonal male contraceptive for humans and animals. Washington State University researchers identified expression of the gene, Arrdc5, in the testicular tissue of mice, pigs, cattle and humans. When they knocked out the gene in mice, it created infertility only in the males, impacting their sperm count, movement and shape. The researchers detailed their findings in the journal Nature Communications. “The study identifies this gene for the first time as being expressed ...
