Supported catalysts are systems in which the active catalytic materials, such as metals, are dispersed on a solid support material, such as alumina, silica, etc. These catalysts are widely used in various chemical processes. Several methods are available for preparing supported catalysts. Among these, the simple impregnation method is particularly suited for industrial settings. In this method, metal precursors and oxide supports are mixed, dried, and crystallized via heat treatment under certain gases. Various high-performance supported catalysts have been prepared using impregnation. However, this method has mostly been used to synthesize conventional monometallic ...

“Shaken, not stirred” — it is widely known how James Bond prefers his martinis. In physics, stirring stretches a fluid into thin streaks, creating turbulence and mixing its properties. In the ocean, a similar process occurs as winds and other forces move seawater. When this happens horizontally over tens to hundreds of kilometres, it is called mesoscale horizontal stirring (MHS). MHS plays a crucial role in redistributing heat, nutrients, and dissolved substances in the upper ocean, shaping plankton distribution and influencing ...

In an era driven by complex data, scientists are increasingly encountering information that doesn’t lie neatly on flat, Euclidean surfaces. From 3D medical scans to robot orientations and AI transformations, much of today’s data lives on curved geometric spaces, called Riemannian manifolds. Analyzing such data accurately has remained a challenge, especially when noise or outliers distort results. To address this, Professor Jongmin Lee from the Department of Statistics, Pusan National University in collaboration with Professor Sungkyu Jung of Seoul National University developed a new statistical method called the ...

Seed plants are essential as a source of food, fuel, medicine, and more. Now, a multidisciplinary team of researchers has combined deep botanical knowledge with powerful genomic technology to decode and mine the DNA of non-flowering seed plants and uncover genes that evolved to help plants build seeds. These findings, published in Nature Communications, may aid scientists in improving seed crop production in agriculture and in the conservation of these ancient endangered seed plants. In this study by members of the New York Plant Genomics Consortium—a multi-institutional collaboration of botanists, evolutionary and genomics scientists, and bioinformaticians—the researchers ...

Depression in young adulthood has a stronger hereditary component and is associated with a higher risk of suicide attempts than depression that begins later in life, according to a new study published in Nature Genetics by researchers at Karolinska Institutet, among others. “We hope that genetic information will be able to help healthcare professionals identify people at high risk of suicide, who may need more support and closer follow-up,” says Lu Yi, senior researcher at the Department of Medical Epidemiology and Biostatistics, Karolinska Institutet, and one of the study’s corresponding authors. Depression is a ...

SOMERVILLE, Mass., November 13, 2025 – Cellarity, a clinical-stage biotechnology company developing Cell State-Correcting therapies through integrated multi-omics and AI modeling, today announced the publication of a seminal manuscript in Nature Communications, which describes a novel framework for the prediction and characterization of drug-induced liver injury (DILI), along with open-source posting of the model and validation data. DILI is one of the most significant safety challenges in developing therapeutics today, as hepatic safety events undetected in preclinical testing ...

In the summer of 2022, 20 islands in the Maldives were flooded when a distant swell event in the Indian Ocean coincided with an extremely high tide level. A new and detailed analysis of that incident, compiled using fieldwork and computer modelling, has shown it to be a relatively rare occurrence with the worst flooding seen in the region since the Boxing Day tsunami of 2004. However, scientists have warned that future predicted rises in sea levels, potentially coupled with an increase in extreme weather events and wave conditions, could result in such flooding becoming far more common, perhaps happening every two to three years by around 2050. It has led them to ...

Affective computing, proposed by Picard in 1997, aims to endow computational systems with the ability to recognize, interpret, and respond to human emotions. Early studies relied primarily on behavioral cues such as facial expressions and voice tone for modelling affective states. Affective computing has entered a new phase—wearable devices are capable of continuously acquiring multimodal physiological signals from multiple sensor channels that differ in terms of sampling frequency, physiological origin, and signal characteristics. In ...

A newly discovered, carnivorous lizard ostensibly represents what most casual onlookers would perhaps perceive to be a dinosaur; however, it is in fact a precursor of the modern crocodile. Named Tainrakuasuchus bellator, partially derived from Latin meaning for “warrior” or “fighter”, this armour-plated reptile lived 240 million years ago just before the dinosaurs. And, as a Pseudosuchia (the precursors of modern crocodiles and alligators), it was among a group of the top, most dominant predators of its time in the Triassic Period. This particular new species – detailed, today, in the peer-reviewed Journal of Systematic Palaeontology – was approximately ...

As artificial vision systems evolve, bridging the gap between sensing and processing remains a key challenge. Now, researchers from the University of Science and Technology of China, led by Prof. Yong Yan and Prof. Haiding Sun, have developed a reconfigurable bioinspired vision sensor using GaN/AlN quantum-disk-in-nanowires (QD-NWs) that emulates the human retina’s dual-cell system—delivering in-sensor computing for high-accuracy human action recognition (HAR). Why This Bioinspired Sensor Matters Dual-Mode ...

Nuclear fusion, which operates on the same principle that powers the Sun, is expected to become a sustainable energy source for the future. To achieve fusion power generation, it is essential to confine plasma at temperatures exceeding one hundred million degrees using a magnetic field and to maintain this high-energy state stably.  A key factor in accomplishing this is the electric potential inside the plasma. This potential governs the transport of particles and energy within the plasma and plays a crucial role in establishing a state in which energy is effectively confined and prevented ...

CHAMPAIGN, Ill. — A naturally occurring protein that tends to be expressed at higher levels in breast cancer cells boosts the effectiveness of some anticancer agents, including doxorubicin, one of the most widely used chemotherapies, and a preclinical drug known as ErSO, researchers report. The protein, FGD3, contributes to the rupture of cancer cells disrupted by these drugs, boosting their effectiveness and enhancing anticancer immunotherapies. The discovery is described in the Journal of Experimental & Clinical Cancer Research. The new findings were the happy result of experiments involving ErSO, an experimental drug that killed 95-100% of estrogen-receptor-positive ...

A widely-used, inexpensive gout drug could reduce heart attacks and strokes in people with cardiovascular disease, according to a new Cochrane review. The review examined the effects of low doses of colchicine, a drug used to treat gout, and found no increase in serious side effects. Cardiovascular disease is often driven by chronic low-grade inflammation, which contributes to recurrent cardiovascular events such as heart attacks and strokes. Colchicine has anti-inflammatory properties that make it a promising option for people with heart disease.  A promising effect on cardiovascular risk The review included 12 randomized controlled trials involving nearly 23,000 ...

EMBARGOED: Hold for release until Wednesday, Nov. 12 at 18:30 ET / 23:30 UK time     Headache disorders affect 3 billion people worldwide—nearly one in every three people, ranking sixth for health loss in 2023  Women experienced more than twice the headache-related health loss of men and spent a greater share of their lives with headache symptoms. Migraine caused nearly 90% of all disability linked to headache disorders, even though tension-type headache was more common.  More than one-fifth of the global headache burden ...

ROCHESTER, Minn. — Mayo Clinic researchers have developed a new tool that can estimate a person's risk of developing memory and thinking problems associated with Alzheimer's disease years before symptoms appear. The research, published in The Lancet Neurology, builds on decades of data from the Mayo Clinic Study of Aging — one of the world's most comprehensive population-based studies of brain health. The study found that women have a higher lifetime risk than men of developing dementia and mild cognitive impairment (MCI), a transitional stage between healthy aging and dementia ...

Extending anti-clotting drugs beyond the initial treatment period of at least 90 days after a first blood clot is linked to lower rates of new clots developing compared with stopping treatment, finds a US study published by The BMJ today. Extended treatment was also linked to higher rates of major bleeding (a common side effect of anti-clotting drugs) but the authors say continued use results in an overall “net clinical benefit.” Guidelines recommend anti-clotting treatment for at least 3-6 months for patients with venous thromboembolism ...

Exposing children to e-cigarettes compromises their human rights. These products should be regulated in a way that puts children’s best interests first and protects them from the harms associated with nicotine consumption in all its forms, argue experts in The BMJ today. Children are now using e-cigarettes at higher rates than adults, write Tom Gatehouse and colleagues. Globally, the World Health Organization (WHO) estimates that 7.2% of children aged 13-15 currently use e-cigarettes. Data indicate use in this group is nine times that of adults, in countries which monitor both groups.  As ...

The rate of high blood pressure (hypertension) in children and adolescents under 19 has nearly doubled, increasing from about 3% in 2000 to over 6% in 2020. More than 9% of children and adolescents have masked hypertension — high blood pressure that only shows up with out-of-office tests, meaning hypertension could be undetected during regular checkups. Nearly 19% of children and adolescents with obesity have hypertension, eight times higher than the prevalence of hypertension in those considered a healthy weight. Approximately 8% of children and adolescents now have prehypertension, a warning sign of potential progression to hypertension, which ...

Global carbon emissions from fossil fuels are projected to rise by 1.1% in 2025 – reaching a record high, according to new research by the Global Carbon Project. The 2025 Global Carbon Budget projects 38.1 billion tonnes of fossil carbon dioxide (CO2) emissions this year. Decarbonisation of energy systems is progressing in many countries – but this is not enough to offset the growth in global energy demand. With projected emissions from land-use change (such as deforestation) down to 4.1 billion ...
