A new research study examined the results from data generated by citizen scientists using a simple web-based motor test. The big data approach provides researchers with a unique way to explore how people correct for motor control errors. The resulting insights may one day pave the way for personalized physical therapy or tailor an athlete’s training routine. The results are available in the January 30th issue of the journal Nature Human Behaviour. “This exploratory approach does not replace lab based studies, but complements ...

New research into the marine phosphorus cycle is deepening our understanding of the impact of human activities on ecosystems in coastal seas.   The research, co-led by the University of East Anglia, in partnership with the Sino-UK Joint Research Centre at the Ocean University of China, looked at the impact of aerosols and river run-off on microalgae in the coastal waters of China.  It identified an ‘Anthropogenic Nitrogen Pump’ which changes the phosphorus cycle and therefore likely coastal biodiversity and associated ecosystem services.  In a balanced ecosystem, microalgae, also known as phytoplankton, provide food for a wide ...

Life has a challenging tempo. Sometimes, it moves faster or slower than we’d like. Nevertheless, we adapt. We pick up the rhythm of conversations. We keep pace with the crowd walking a city sidewalk.  “There are many instances where we have to do the same action but at different tempos. So the question is, how does the brain do it," says Cold Spring Harbor Laboratory Assistant Professor Arkarup Banerjee.  Now, Banerjee and collaborators have uncovered a new clue that suggests the brain bends our processing of time to suit our ...

People of religious faith may have experienced lower levels of unhappiness and stress than secular people during the UK’s Covid-19 lockdowns in 2020 and 2021, according to new University of Cambridge research. The findings follow a recently published Cambridge-led study suggesting that worsening mental health after experiencing Covid infection – either personally or in those close to you – was also somewhat ameliorated by religious belief. This study looked at the US population during early 2021. University of Cambridge economists argue ...

The AD-RIDDLE programme will offer healthcare professionals a suite of validated solutions for timely detection and diagnosis of Alzheimer’s disease and dementias, to match individuals with the right interventions at the right time, enabling people to better understand what they can do to reduce risk and prevent cognitive decline. Alzheimer’s disease represents a major public ...

HONG KONG (18 Jan 2024) — Goats can tell the difference between a happy-sounding human voice and an angry-sounding one, according to research co-led by Professor Alan McElligott, an expert in animal behaviour and welfare at City University of Hong Kong (CityUHK). The study reveals that goats may have developed a sensitivity to our vocal cues over their long association with humans, according to the study published in Animal Behaviour. Long known for their own sonorous vocal skills, goats in the study tended to spend longer gazing towards the source of the sound after a change in the valence of a human voice, i.e., when the playback switched from a happier to ...

Cambridge scientists may have discovered a new way in which fasting helps reduce inflammation – a potentially damaging side-effect of the body’s immune system that underlies a number of chronic diseases. In research published in Cell Reports, the team describes how fasting raises levels of a chemical in the blood known as arachidonic acid, which inhibits inflammation. The researchers say it may also help explain some of the beneficial effects of drugs such as aspirin. Scientists have known for some time that our diet – particular a high calorie Western diet – can increase our risk of diseases ...

Every fluid — from Earth’s atmosphere to blood pumping through the human body — has viscosity, a quantifiable characteristic describing how the fluid will deform when it encounters some other matter. If the viscosity is higher, the fluid flows calmly, a state known as laminar. If the viscosity decreases, the fluid undergoes the transition from laminar to turbulent flow. The degree of laminar or turbulent flow is referred to as the Reynolds number, which is inversely proportional to the viscosity. The Reynolds law of dynamic similarity or Reynolds similitude, states that if two fluids flow around similar structures with different length ...

There is substantial geographic variation across the U.S. health care system to diagnose and treat early-stage Alzheimer’s disease with disease-modifying therapies, and engaging primary care providers in the effort may be a key to accelerating delivery of emerging new treatments, according to a new RAND report.   Enabling primary care practitioners to diagnose and evaluate patients for treatment eligibility would make the biggest impact on reducing wait times for specialists and increase the number of people treated with disease-modifying therapies from 2025 through 2044.   While primary care providers are technically capable of performing cognitive assessments, ...

A new causal link has been found between the presence of oncofoetal ecosystems and recurrence and response to immunotherapy in primary liver cancer, hepatocellular carcinoma (HCC) The findings will pave the way to use the presence of oncofoetal ecosystems as a biomarker to treat HCC, a disease with a poor prognosis that is typically diagnosed late Singapore, 30 January 2024 - A team of clinician-scientists and researchers from the National Cancer Centre Singapore (NCCS), Agency for Science, Technology and Research (A*STAR), the Harry Perkins Institute of Medical Research and global research partners, has found a causal link between the presence of oncofoetal ...

Hf-based carbides are highly desirable candidates for thermal protection applications above 2000 ℃ due to their extremely high melting point and favorable mechanical properties. However, as a crucial indicator for composition design and performance assessment, the static oxidation behavior of Hf-based carbides at their potential service temperatures has been rarely studied. In a study published in the KeAi journal Advanced Powder Materials, a group of researchers from Central South University and China Academy of Launch Vehicle Technology revealed the static oxidation mechanism ...

Laser sources operating at the 1.2 μm wavelength band have some unique applications in photodynamic therapy, biomedical diagnosis and oxygen sensing. Additionally, they can be adopted as pump sources for mid-infrared optical parametric generation as well as visible light generation by frequency doubling. Laser generation at 1.2 μm waveband has been achieved with different solid-state lasers including semiconductor laser, diamond Raman laser, and fiber laser. Among these three types, fiber laser thanks to its simple structure, good beam quality, and operation flexibility, is a great choice for 1.2 μm waveband laser generation.   Researchers ...

We know that our climate is changing. Extreme weather events are becoming more common, sea levels are rising and overall, our planet is getting warmer. Monitoring these changes is critical. One of the best indicators of climate change is the Ocean Heat Content (OHC) estimate, a measurement of overall oceanic temperature calculated by gathering water temperature data in oceans around the world in differing locations, at varying depths and across time. The data necessary to calculate the OHC over such a wide-spread area is gathered by the Global Ocean Observing System (GOOS), an integrated network of platforms ...

Soil microbiome has far-reaching significance, particularly for rice production, which can be better explained with a Japanese proverb: “Rice grows with soil fertility, while upland crops depend on fertilization”. Therefore, understanding the paddy field microbiome is crucial for sustainable soil fertility and rice production. This would also lead us to overcome the global food shortage problem as rice is the primary food source for nearly half of the world's population.  Among the paddy field microbes, bacteria, fungi, and archaea are well-studied, while protists, the vast majority of eukaryotes, are largely unknown. Protists are the most diverse eukaryotic microorganisms ...

Ahead of the 2024 US presidential election, The BMJ today launches a forward-looking 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. The articles, written by leading clinicians and researchers across the US, explore topics such as how systemic racism and economic inequality contributed to covid-19 disparities; mass incarceration and poor prison health as a driver of the pandemic; ...

An analysis published today in the The BMJ examines the risks faced by frontline workers in the United States during the pandemic and suggests reforms that could protect population health and save lives. Lead author Professor David Michaels at the George Washington University and his colleagues note that from the onset laws and regulations in the United States inadequately protected frontline workers. The gaps allowed a rapid spread of disease in US workplaces like meat packing plants. At the same time, these essential workers were rarely seen as a population that needed special attention ...

CAMBRIDGE, MA – An intricate, honeycomb-like structure of struts and beams could withstand a supersonic impact better than a solid slab of the same material. What’s more, the specific structure matters, with some being more resilient to impacts than others. That’s what MIT engineers are finding in experiments with microscopic metamaterials — materials that are intentionally printed, assembled, or otherwise engineered with microscopic architectures that give the overall material exceptional properties. In a study appearing today in the Proceedings of the National Academy of Sciences, the engineers report on a new way ...

Global tree-planting campaigns have reached fad-like proportions over the past decade, and it’s easy to understand their appeal. Healthy forests help in the fight against climate change by absorbing some of our excess carbon dioxide emissions, and they can provide wildlife habitat and quality-of-life benefits for local human communities too. So why not plant more trees? It seems like an easy win.  But the problem is, there’s a huge difference between simply planting a tree and making sure that trees survive and grow over the long-term. And without the necessary ecological understanding or long-term planning and ...

New research from University of Utah psychology researchers is helping prove what American authors John Muir and Henry David Thoreau tried to teach more than 150 years ago: Time spent in nature is good for the heart and soul. Amy McDonnell and David Strayer are showing it is good for your brain, too. Their latest research, conducted at the university’s Red Butte Garden, uses electroencephalography (EEG), which records electrical activity in the brain with small discs attached to the scalp, to measure participants’ attentional capacity. “A walk in nature enhances certain executive control processes in the brain above and beyond the benefits associated with exercise,” ...
