Firstly, the authors provided a detailed explanation of the experimental methods and procedures. This study recruited 30 healthy subjects (15 males and 15 females), aged between 20 to 50 years, with an average age of 42 ± 6.58 years. All participants had no severe visual or auditory impairments and were right-handed. The subjects met the biometric standards for astronaut candidates and were rigorously screened. The experiment used Unity 3D to model the space station, simulating the internal scenes of the space station. The subjects started from the core node module and found the laboratory module I, where they operated the Space Raman Spectrometer ...

Plastic items from around the world are continuously washing ashore on Norwegian coastlines. This reflects a much larger systemic issue facing the nations of the world. Scientists have long reported the consequences of plastic pollution and the urgent need for intervention, but global plastic production and consumption continue to rise. This underscores the importance of Norway’s advocacy for a global agreement that guarantees stopping the flow of plastics into the environment. But Norway also has a responsibility in generating plastic pollution. In a study conducted ...

A new study of curriculum reading material at the University of Glasgow finds that 94% of recommended Tropical Ecology authors are white, and that 80% of authors are affiliated with universities outside of the tropics. Dr Stewart White, Senior Lecturer at the School of Biodiversity, One Health and Veterinary Medicine at the University of Glasgow, UK, intends to change that. “Tropical rainforest research was long the preserve of rich white men and the resulting literature was the same,” says Dr White. “This historical bias in tropical research and publication is still ...

New research reveals how the surprising internal anatomy of the helmeted hornbill’s casque allows it to withstand damage during aerial jousting battles with rivals. Researchers hope that this new understanding can help to conserve this critically endangered species, as well as provide new insights into developing impact-resistant bio-mimetic materials. “When I started in Hong Kong, I visited City University of Hong Kong (HKU)’s conservation forensics group to chat about their research and they introduced me to this amazing bird, to its ...

Researchers have discovered the unique nanostructures responsible for the electric blue spots of the bluespotted ribbontail ray (Taeniura lymma), with possible applications for developing chemical-free colouration. The team are also conducting ongoing research into the equally enigmatic blue colouration of the blue shark (Prionace glauca). Skin colouration plays a key role in organismal communication, providing life-critical visual clues that can warn, attract or camouflage. Bluespotted ribbontail ...

Painting roofs white or covering them with a reflective coating would be more effective at cooling cities like London than vegetation-covered “green roofs,” street-level vegetation or solar panels, finds a new study led by UCL researchers. Conversely, extensive use of air conditioning would warm the outside environment by as much as 1 degree C in London’s dense city centre, the researchers found. The research, published in Geophysical Research Letters, used a three-dimensional urban climate model of Greater London to test the thermal effects of different passive and active urban heat management systems, including painted “cool roofs,” rooftop solar panels, ...

One of the challenges of cramming smarter and more powerful electronics into ever-shrinking devices is developing the tools and techniques to analyze the materials that make them up with increasingly intimate precision. Physicists at Michigan State University have taken a long-awaited step on that front with an approach that combines high-resolution microscopy with ultrafast lasers. The technique, described in the journal Nature Photonics, enables researchers to spot misfit atoms in semiconductors with unparalleled precision. Semiconductor physics labels these atoms as “defects,” which sounds negative, but they’re ...

UNIVERSITY PARK, Pa. — Treating cancer can sometimes feel like a game of Whac-A-Mole. The disease can become resistant to treatment, and clinicians never know when, where and what resistance might emerge, leaving them one step behind. But a team led by Penn State researchers has found a way to reprogram disease evolution and design tumors that are easier to treat. They created a modular genetic circuit that turns cancer cells into a “Trojan horse,” causing them to self-destruct and kill nearby drug-resistant ...

Pancreatic cancer is a particularly aggressive and difficult-to-treat cancer, in part because it is often resistant to chemotherapy. Now, researchers at Stanford have revealed that this resistance is related to both the physical stiffness of the tissue around the cancerous cells and the chemical makeup of that tissue. Their work, published on July 4 in Nature Materials, shows that this resistance can be reversed and reveals potential targets for new pancreatic cancer treatments. “We found that stiffer tissue can cause pancreatic cancer cells to become resistant to chemotherapy, while softer tissue made ...

Findings published in a new peer-reviewed paper in the British Journal of Educational Studies challenges the idea that academically selective schools are necessary for clever pupils to achieve good outcomes. Selective schools are government-funded schools that enrol only the highest performing students. Pupils take a standardized entrance exam, from which the best-scoring are enrolled. Some argue that selective schools are necessary for bright pupils to reach their full academic potential. Selective schools can ...

One of the greatest mysteries of science could be one step closer to being solved. Approximately 80% of the matter in the universe is dark, meaning that it cannot be seen. In fact, dark matter is passing through us constantly – possibly at a rate of trillions of particles per second. We know it exists because we can see the effects of its gravity, but experiments to date have so far failed to detect it. Taking advantage of the most advanced quantum technologies, scientists from Lancaster University, the University of Oxford, and Royal Holloway, ...

What types of cities exist in Europe and which are more favourable in terms of human health, environmental quality and carbon footprint? To answer these questions, a study led by the Barcelona Institute for Global Health (ISGlobal), a centre supported by the "la Caixa" Foundation, has analysed 919 European cities. The research, published in The Lancet Planetary Health, identified four basic urban configurations on the continent: compact-high density cities, open lowrise-medium density cities, open lowrise-low density cities and green-low density cities. The results show that greener and less densely populated ...

Reducing consumption of processed meat by around one-third could prevent more than 350,000 cases of diabetes in the US over 10 years, a study suggests. Cutting US adults’ processed meat intake by 30 per cent – the equivalent of around 10 slices of bacon a week – would also lead to tens of thousands of fewer cases of cardiovascular disease and colorectal cancer, researchers say. A team from the University of Edinburgh’s Global Academy of Agriculture and Food Systems together with the University of North Carolina, Chapel Hill, has developed ...

Stem cell-based embryo models (SCBEMs) are three-dimensional biological structures that mimic aspects of early human embryo development. They can be created in the lab from stem cells, and can provide new insights into critical stages of early human development that are normally inaccessible to researchers. Embryo model work is expected to lead to new interventions for a range of conditions, including revolutionising treatments for recurrent miscarriage, understanding developmental disorders and improving the success rate of IVF. Although embryo models are not the same ...

Tampons from several brands that potentially millions of people use each month can contain toxic metals like lead, arsenic, and cadmium, a new study led by a UC Berkeley researcher has found. Tampons are of particular concern as a potential source of exposure to chemicals, including metals, because the skin of the vagina has a higher potential for chemical absorption than skin elsewhere on the body. In addition, the products are used by a large percentage of the population on a monthly basis—50-80% of those who menstruate use tampons—for several hours at a time. “Despite this large potential for public health concern, very little research ...
