Concreting mistakes can be expensive. Concrete poured too quickly often leads to a lack of colour uniformity, irregularities in the structure and uneven surfaces. Particularly in the case of exposed concrete, expensive reworking using concrete cosmetics is then necessary, sometimes a wall may even have to be demolished. In addition, if the fresh concrete rises too quickly in the formwork, there is a certain risk potential for the workers, as this can cause the formwork to break. In their DigiCoPro project, Ralph Stöckl and ...

Tokyo, Japan – Although it is the smallest and lightest atom, hydrogen can have a big impact by infiltrating other materials and affecting their properties, such as superconductivity and metal-insulator-transitions. Now, researchers from Japan have focused on finding an easy way to locate it in nanofilms. In a study published recently in Nature Communications, researchers from the Institute of Industrial Science, The University of Tokyo have reported a method for determining the location of hydrogen in nanofilms. Because they are very small, hydrogen atoms can easily migrate into the framework of other materials. Titanium absorbs hydrogen to give titanium hydrides, making ...

A new study suggests that political abuse is a key feature of political communication on social media platform, ‘X’, and whether on the political left or right, it is just as common to see politically engaged users abusing their political opponents, to a similar degree, and with little room for moderates. While previous research into such online abuse has typically focused on the USA, the current study found that abuse followed a common ally-enemy structure across the nine countries for which there was available data: Canada, France, Germany, Italy, Poland, Spain, Turkey, ...

(Santa Barbara, Calif.) — A remote lakeshore deep inside Yosemite National Park teems with life: coyotes, snakes, birds, tadpoles, frogs. The frogs are at the heart of this scene, which a decade ago was much different. It was quiet — and not in a good way. The frogs that are so central to this ecosystem were absent, extirpated by a deadly fungal disease known as amphibian chytrid fungus. Now, thanks to the consistent and focused efforts of researchers and conservationists to save, then reintroduce, mountain yellow-legged frogs to this and numerous other lakes in Yosemite, their populations are again thriving. A ...

ITHACA, N.Y. – By probing chemical processes observed in the Earth’s hot mantle, Cornell scientists have started developing a library of basalt-based spectral signatures that not only will help reveal the composition of planets outside of our solar system but could demonstrate evidence of water on those exoplanets. “When the Earth’s mantle melts, it produces basalts,” said Esteban Gazel, professor of engineering. Basalt, a gray-black volcanic rock found throughout the solar system, are key recorders of geologic history, he said. “When the Martian mantle melted, it also produced basalts. The moon is mostly basaltic,” he said. “We’re ...

Embargoed until 4 a.m. CT / 5 a.m. ET Thursday, November 14, 2024 DALLAS and WASHINGTON, Nov. 14, 2024 — The American Heart Association and the American Red Cross today released the “2024 Guidelines for First Aid,” which provide critical updates that equip first aid responders with the latest evidence-based practices to effectively respond to mild, moderate and life-threatening emergencies. The guidelines are published today in Circulation, the American Heart Association’s flagship journal. “Providing first aid care is about recognizing that an emergency ...

The COVID-19 pandemic led to heightened public interest in learning about viruses and how they can cause diseases. There has been a lot of focus on communicating virology concepts to the general public in order to increase awareness about the spread and prevention of viral diseases. When it comes to teaching biology, however, how do we explain microscopic processes like viral infections to students in the classroom? In modern science education, seeing is believing—educators are now attempting to capture the attention of students by using eye-catching visuals and videos, instead ...

By exploiting the genetic variation in cancer cells, an already approved cancer drug demonstrated enhanced effects against cancer cells in specific patient groups. This is shown in a recent study from Uppsala University, published in the journal eBiomedicine. The findings suggest a potential for more individually tailored and more effective cancer therapies. The human genome is organised in 46 chromosomes, where all but the x and y chromosomes in men are present in two copies. This means that a person with a faulty gene on one chromosome most often has a functional version on the other. But during ...

Tel Aviv, Israel, 14 November 2024 – Tel Aviv University researchers have made a remarkable discovery that could revolutionize our understanding of genetic mutations and their role in brain development. The study, published today in Genomic Psychiatry, reveals that not all genetic mutations are harmful – some may actually offer protection against developmental disorders. Led by Professor Illana Gozes, Director, The Elton Laboratory for Molecular Neuroendocrinology, the research team identified a protective inherited mutation in the Activity-Dependent Neuroprotective Protein (ADNP) gene. This finding challenges the traditional ...

MEDELLÍN, Colombia, November 14, 2024 - In a breakthrough that bridges the gap between neurodevelopment and neurodegeneration, Dr. Natalia Acosta-Baena has identified a novel genetic syndrome that reshapes our understanding of brain disorders. Her research, featured in the latest Genomic Press Interview, reveals how a single gene involved in neuronal transport can influence both brain development and degeneration. Dr. Acosta-Baena's discovery of a SPAG9 variant's role in both processes challenges the traditional view that neurodevelopmental disorders and neurodegeneration operate through distinct pathways. ...

Many young girls in low- and middle-income countries become pregnant early, which can be dangerous for them and for their babies. Studies show that girls who stay in school are less likely to get pregnant at a young age. Financial support can encourage girls to stay in school and delay pregnancy and marriage in some settings. However, a new large study from Zambia found that two years of financial support combined with comprehensive sexuality education and community dialogue meetings, moderately reduced ...

Vitamin D, an essential nutrient, is naturally produced through sun exposure and certain foods. However, excessive sunburn prevention measures are causing a severe problem of vitamin D deficiency, particularly among young women in Japan. Since vitamin D deficiency is also related to pregnancy-induced hypertension and low birth weight in children, it is important to quickly identify those at high risk and provide appropriate health guidance. However, the method currently established for measuring serum vitamin D levels is expensive and ...

Cannabis use causes cellular damage that increases the risk of highly cancerous tumours, according to a new paper published in the scientific journal Addiction Biology.  The paper describes cannabis as a “genotoxic” substance because it damages a cell's genetic information, which can lead to DNA mutations, accelerated aging, and cancer.  To make matters worse, this genotoxicity may be transmitted via damaged egg and sperm to the cannabis user’s offspring, making the risk of cannabis ...

Orlando, Fla - For those striving to maintain a healthy lifestyle, holiday celebrations can feel like a minefield of dietary pitfalls, bound to derail the progress you’ve made through diet and exercise the rest of the year. In fact, a new national survey by Orlando Health finds nearly two in five (39%) Americans worry about how much they eat over the holidays. The good news is that dietitians say there’s no need to feel guilty about a few holiday treats. “Holidays come around once a year, and indulging in a few traditional foods and favorite recipes that may have a little extra ...

Fifty years of change on iconic limestone pavements has revealed mixed fortunes for one of the most distinctive landscapes in the UK. The landscapes - which will be familiar to visitors to the Yorkshire Dales and fans of Harry Potter and the Deathly Hallows film – have, in many places, seen reductions of specialist species and more common less desirable species become more abundant.  However, it is not all bad news as the picture is very mixed across the UK’s areas of limestone pavement with some areas increasing in plant biodiversity. The ...

‘Green flight paths’ between key global locations could help to fast-track fully decarbonised aviation, according to research led by an international team based at Heriot-Watt University in the United Kingdom and the American University of Sharjah in the United Arab Emirates.  The research, published in the in the Royal Society of Chemistry’s top international journal, Energy and Environmental Science, recommends that a small number of long-haul flights with high passenger volumes, ...

A new paper shows how partnering with the community can lead to more inclusive health care, especially for individuals with autism and other neurodevelopmental disabilities. The article, published this week in Pediatrics, details the success of a unique COVID-19 and flu vaccine clinic at the UC Davis MIND Institute. The clinic team includes developmental-behavioral pediatricians, child life specialists, nurses, psychologists, social workers and staff trained to help families navigate health care. The goal is not only to administer vaccines, but to help patients build skills needed to successfully complete medical procedures for the rest of their lives. Listening to ...

In a significant step towards achieving the "Carbon Peaking and Carbon Neutrality" goals, researchers at the Chinese Academy of Sciences, University of Chinese Academy of Sciences, Beijing Institute of Technology, in collaboration with Hohai University, have developed a groundbreaking dual-layer optimization strategy for park-level integrated energy systems (PIES). This strategy, which integrates electricity and heat demand response, significantly boosts the economic efficiency and low-carbon operation ...

Hamilton, ON, Nov. 14, 2024, In a groundbreaking study, researchers at McMaster University have identified a potential treatment for Sandhoff and Tay-Sachs diseases—two rare, often fatal lysosomal storage disorders that cause progressive damage to nerve cells in the brain and spinal cord. After years of investigating the diseases’ underlying mechanisms, the research team has identified an existing FDA-approved drug that could significantly improve quality of life for affected patients and their families. “Sandhoff and Tay-Sachs are devastating diseases,” ...

Since 2018, Sino-US economic and trade relations have become increasingly tense. Between 2018 and 2019, the US imposed seven rounds of tariffs on China, to which China responded with retaliatory measures. The simple average tariff rates on US imports from China rose from 4.07% in January 2018 to 24.43% in December 2019, while the simple average tariff rates on Chinese imports from the US increased from 9.32% in January 2018 to 22.53% in December 2019 (see figure 1). Consequently, the share of Chinese goods in US imports declined significantly — ...

We have probably all seen a soybean plant, about 1 meter high with leaves and pods compactly arranged on a main stem with a few short side branches. The wild relative of the domesticated soybean is a long vine with pods widely distributed on many side branches. Plant breeding by farmers thousands of years ago is to thank for this dramatic change. As human population increases and protein demand doubles, modern plant breeders must further optimize soybean plant architecture and per plant yield for modern farming systems. Conventional ...

Lancaster University researchers investigating consumer attitudes and behaviours around plastic food packaging have found UK households are ‘wishcycling’ rather than recycling – and say it’s a problem that everyone - government, food producers, waste management and residents – has to solve. Wishcycling – the act of putting packaging in recycling bins and hoping for the best, rather than knowing it’s recyclable – is something households are doing due to confusing product labels and differing recycling facilities around the country, experts warn. The academics behind Lancaster ...

A small clinical trial shows promising results for patients with triple-negative breast cancer who received an investigational vaccine designed to prevent recurrence of tumors. Conducted at Washington University School of Medicine in St. Louis with a therapy designed by WashU Medicine researchers, the trial is the first to report results for this type of vaccine — known as a neoantigen DNA vaccine — for breast cancer patients. The study, which found the vaccine to be well-tolerated and to stimulate ...

Adverse events affect more than a third (38%) of adults undergoing surgery, finds a study of admissions to 11 hospitals in the US state of Massachusetts, published by The BMJ today. Of the 1009 admissions analysed, nearly half were classified as major (resulting in serious, life threatening or fatal harm) and the majority were considered as potentially preventable. Although this study may not fully represent hospitals at large, the findings show that “adverse events remain widespread in contemporary ...

Outsourcing adult social care services in England to the private sector since the 1980s has led to worse care and should be rolled back, argue experts in The BMJ today. Benjamin Goodair at the Blavatnik School of Government, University of Oxford and colleagues suggest that removing the profit motive would help improve quality and reduce inequities. Social care, sometimes referred to as community, residential, or personalised care, for older people and people with physical and mental disabilities is facing record demand but performing worse than any time in recent history, they explain. One contributor to this, they say, is the outsourcing of care provision from the ...
