Researchers have developed a “self-driving” lab that uses artificial intelligence (AI) and automated systems to provide in-depth analyses of catalytic reactions used in chemical research and manufacturing. The new tool, called Fast-Cat, can provide more information in five days than is possible in six months of conventional testing. At issue are the yield and selectivity of chemical reactions in the presence of molecules called ligands. Yield refers to how efficiently a chemical reaction produces a desired product from the chemicals you started with. Selectivity refers ...

Are museums, theaters, and opera houses truly walking the talk when it comes to social and environmental sustainability? The University of Lausanne (UNIL) delved into this pressing question, conducting an international survey with over 200 major cultural organizations. The verdict? While there's significant room for improvement across the spectrum, Anglophone countries lead the charge. Cultural organizations, with their wide-reaching influence and power to shape narratives and imaginations, are poised to ...

Tomato (Solanum lycopersicum L.) is the most widely cultivated and consumed horticultural crop. At present, saline–alkali is an important abiotic stress source that affects tomato production. Exogenous methyl jasmonate (MeJA) can enhance the resistance of tomatoes to various stress, but its exact mechanism is still unclear. In January 2024, Horticulture Research published a research entitled by “SlWRKY80-mediated jasmonic acid pathway positively regulates tomato resistance to saline-alkali stress by enhancing spermidine content and stabilizing ...

The impact of abdominal fat on brain health and cognition is generally more pronounced in middle-aged men at high risk of Alzheimer’s disease as opposed to women, according to researchers at Rutgers Health.   In middle-aged individuals with a family history of Alzheimer’s disease, the amount of fat in their abdominal organs (pancreas, liver, and belly fat) is related to their brain volumes and cognitive function, according to the study published in the journal Obesity. The study was written by Sapir Golan Shekhtman, a Ph.D. student at the Joseph Sagol Neuroscience Center at the Sheba Medical Center in Israel and led by ...

ROCKVILLE, Md.— High-fat diets cause obesity in male mice. The underlying mechanism, however, remains controversial. After assessing three contrasting ideas, researchers have determined that the hedonic overdrive model provides the best fit, according to a new study published in the journal Obesity, The Obesity Society’s (TOS) flagship journal. “Our work provides some direction as to why high-fat/high-carb macronutrient combinations stimulate overconsumption. The study is in mice so we ...

The tone and tuning of musical instruments has the power to manipulate our appreciation of harmony, new research shows. The findings challenge centuries of Western music theory and encourage greater experimentation with instruments from different cultures.     According to the Ancient Greek philosopher Pythagoras, ‘consonance’ – a pleasant-sounding combination of notes – is produced by special relationships between simple numbers such as 3 and 4. More recently, scholars have tried to find psychological explanations, but these ‘integer ratios’ are still credited with making a chord sound beautiful, and deviation from them ...

A new paper in Genome Biology and Evolution, published by Oxford University Press, finds that the link between paternal age and rare congenital disorders is more complex than scientists had previously thought. While researchers have long realized that older fathers are more likely to have children with bone and heart malformations, such as Achondroplasia, Apert, or Noonan syndrome or neurodevelopmental disorders, schizophrenia, and autism, new examination indicates that while the link between some pathogenic mutations increases with paternal age, others do not and may even occur in the father’s testis before sexual maturity. Delayed fatherhood results in a higher ...

A study into parental smoking and childhood obesity has challenged previous notions by revealing that the links between the two are not confined to a specific socio-economic group.  The data shows a strong correlation between parents who smoke and their children’s consumption of high calorie unhealthy foods and drinks, across social classes.  Using longitudinal data on 5,000 Australian children collected over a 10-year period, the research found those living with parents who smoke, on average, eat less healthy, higher calorie food such as fruit juice, sausages, fries, snacks, full fat milk products, ...

The success of a deep learning-based network intrusion detection systems (NIDS) relies on large-scale, labeled, realistic traffic. However, automated labeling of realistic traffic, such as by sand-box and rule-based approaches, is prone to errors, which in turn affects deep learning-based NIDS. To solve the problems, a research team led by Yuefei ZHU published their new research on 15 Feb 2024 in Frontiers of Computer Science co-published by Higher Education Press and Springer Nature. The team ...

Researchers at the Centre for Genomic Regulation (CRG) reveal that the Snhg11 gene is critical for the function and formation of neurons in the hippocampus. Experiments with mice and human tissues revealed the gene is less active in brains with Down syndrome, potentially contributing to the memory deficits observed in people living with the condition. The findings are published today in the journal Molecular Psychiatry.   Traditionally, much of the focus in genomics has been on protein-coding genes, which in humans constitutes around just 2% of the entire genome. The rest is "dark ...

In The BMJ today, Keisha Bentley-Edwards at Duke University, North Carolina, and colleagues argue that systemic racism and economic inequality are at the root of disparity in covid-19 outcomes and suggest how to distribute resources more equitably.  The article is part of a series that highlights the lessons that can be learned from the US’s covid-19 experience and the actions that are needed to prevent the loss of another million citizens in the next pandemic and improve and protect population health. "Rather than waiting for the next pandemic to address systemic failures, the ...

A group led by researchers at Nagoya University and Meijo University in Japan has developed a disinfection technology that uses low-temperature plasma generated by electricity to cultivate environmentally friendly hydroponically grown crops. This innovative technology sterilizes the crops, promoting plant growth without the use of chemical fertilizers. Their findings appeared in Environmental Technology & Innovations. In hydroponic agriculture, farmers cultivate plants by providing their roots with a nutrient solution. However, the nutrient solution can become infected with pathogenic E. coli strains, contaminating the crop and leading to foodborne illnesses. To avoid ...

Allyship — the practice of relatively advantaged group members acting with the intention to support, advocate and improve circumstances for relatively disadvantaged groups — is critical to promoting more inclusive and equitable organizations. Not only are advantaged group members typically received more favorably within an organization than disadvantaged group members would be when they speak out against injustice, their allyship can improve disadvantaged group members’ psychological experience in the organization. For instance, men are more likely to believe other men, compared with women, when they confront sexism. And Black Americans report higher levels of self-esteem ...

Researchers at the University of Illinois at Urbana-Champaign have shown for the first time that expensive aberration-corrected microscopes are no longer required to achieve record-breaking microscopic resolution. The field of microscopy is in the middle of a great revolution. Since the 1800s and the invention of the compound light microscope, there have only been a few major jumps in resolution to see different length scales: from bacteria and cells, to viruses and proteins, and even down to single atoms. Generally, ...

Black carbon is the most dangerous air pollutant you’ve never heard of. Its two main sources, diesel exhaust and wood smoke from wildfires and household heating, produce ultrafine air particles that are up to 25 times more of a health hazard per unit compared to other types of particulate matter. Despite its danger, black carbon is understudied due to a lack of monitoring equipment. Regulatory-standard sensors are wildly expensive to deploy and maintain, resulting in sparse coverage in regions infamous for poor air quality, such as the greater Salt Lake City metropolitan area in Utah. A University of Utah-led study found that the AethLabs ...
