Overview: Researchers at the Toyohashi University of Technology and the University of Tokyo developed a system that provides a virtual walking experience to a seated person by real-time synthesis of a walking avatar and its shadow on a 360-degree video with vibrations to the feet. The shadow of the avatar induces an illusory presence of their body. In the future, it is expected to provide an immersive experience for any recorded medium with a virtual embodiment.   Details: Walking is a fundamental activity for humans ...

Difficult-to-cut materials such as titanium alloys, high-temperature alloys, metal/ceramic/polymer-matrix composites, hard and brittle materials, as well as geometrically complex components such as thin-walled structures, micro channels and complex surfaces, are widely used in aerospace community. Nevertheless, many problems including severe and rapid tool wear, low machining efficiency, and poor surface integrity exist in mechanical machining. How to efficiently and precisely process these materials and components, i.e., make difficult-to-cut ...

In the context of the gradual depletion of fossil fuels and the energy crisis, hydrogen energy has attracted widespread attention due to its ultra-high energy density and eco-friendly properties. However, most of the hydrogen production still relies on fossil fuels, with less than 1 million tonnes produced as low-emission hydrogen in 2021, which means it has limited benefits in mitigating the energy crisis and environmental degradation. Alternatively, hydrogen production via water electrolysis has the advantages ...

An innovative Oregon Health & Science University research program that enlists older Black adults to walk through and reminisce about historically Black neighborhoods in Portland — which now look very different after rapid change through gentrification — may help improve cognitive function, a new study finds. The OHSU project has gained wide interest since its 2016 launch, with similar versions beginning to take root in Seattle and Oakland, California.   Now, newly published research suggests it may improve brain health in a population that’s disproportionately affected by Alzheimer’s disease. The study, published online ...

Supported by a $2 million R01 grant from the National Institutes of Health, the Auerbach Lab at the Beckman Institute for Advanced Science and Technology will examine how different genes associated with autism spectrum disorders may similarly impact our brain’s neurons, resulting in heightened sensitivity to sounds. Autism spectrum disorders are genetically complex, and hundreds of genes are implicated in their development. As a result, some may conclude that autism is a collection of disconnected disorders with comparable symptoms. However, much like how roads converge as they approach a destination, at some level of brain function ...

A basic premise of how plants grow is that shoots grow up and roots grow down. A new study, published in Plant Physiology, a leading international society journal published by the American Society of Plant Biologists, reveals the answer to a fascinating question: why do weeping tree varieties defy this natural growth pattern? Researchers identified a protein called WEEP that is missing from the Weeping Peach Tree. Their results show how a DNA deletion in just one gene completely changes the localization of the hormone auxin, which ...

A new review has concluded that hospitals that are privatised typically deliver worse quality care after converting from public ownership. The study, led by University of Oxford researchers, has been published today in The Lancet Public Health (video summary available in the notes section).. Lead author Dr Benjamin Goodair, postdoctoral researcher at the Department of Social Policy and Intervention at the University of Oxford, said: ‘This review challenges the justifications for healthcare privatisation and concludes that the scientific support for healthcare privatisation ...

Consistent evidence shows that higher exposure to ultra-processed foods is associated with an increased risk of 32 damaging health outcomes including cancer, major heart and lung conditions, mental health disorders, and early death. The findings, published by The BMJ today, show that diets high in ultra-processed food may be harmful to many body systems and underscore the need for urgent measures that target and aim to reduce dietary exposure to these products and better understand the mechanisms linking ...

Many cancer drugs approved by the European Medicines Agency (EMA) between 1995 and 2020 lack proof of added benefit, particularly those approved through expedited (“fast track”) pathways, finds a study published by The BMJ today. And despite pharmaceutical industry claims that high drug prices are needed to offset research and development (R&D) costs, the results show that more than half of these drugs, including those with minimal or no added benefit, recover R&D expenses within three years. As such, the researchers call for better alignment between regulatory and reimbursement processes, particularly for drugs approved through expedited pathways, to promote development ...

Peer-reviewed / Modelling study / People The Lancet Public Health: Menu calorie labelling may reduce deaths from cardiovascular disease in England, modelling study suggests  The first estimates of the impact of the current calorie labelling legislation in England, which applies only to large out-of-home food businesses, suggests the policy could prevent or postpone about 730 deaths from cardiovascular diseases between 2022 to 2041.  Larger health benefits are estimated if the policy were to be implemented in all English out-of-home food businesses, with about 9,200 deaths from cardiovascular diseases potentially prevented over ...

An increasing number of seismologists are using fiber optic cables to detect seismic waves on Earth—but how would this technology fare on the Moon, and what would it tell us about the deep layers of our nearest neighbor in space? In Seismological Research Letters, Wenbo Wu of Woods Hole Oceanographic Institute and colleagues explore the idea of deploying a fiber seismic network on the Moon, discussing some of the challenges to overcome. They also test this hypothetical network using artificial seismograms created from data collected by seismometers placed on the Moon’s surface ...

A major research programme led by the University of East Anglia (UEA) has quantified how climate change risks to human and natural systems increase at a national scale as the level of global warming increases.  A collection of eight studies – all focusing on Brazil, China, Egypt, Ethiopia, Ghana and India - shows that the risks of drought, flooding, declines in crop yields, and loss of biodiversity and natural capital greatly increase for each additional degree of global warming.  The overarching picture for the accrual of climate risk across these ...

Sensory cues from the opposite sex can influence how animals age, a University of Otago-led study has found.   Lead author Associate Professor Mike Garratt, of the Department of Anatomy, says research has previously shown interactions with the opposite sex can speed up ageing. This study has built on that by showing sensory cues alone can drive those effects.   “This provides an example of how information detected by our sensory systems – what we see, hear and smell – can have long term effects on our ...

Low-income households in the United States are bearing an energy burden that is three times that of the average household, according to the U.S. Department of Energy. In total, more than 46 million U.S. households carry a significant energy burden — meaning they pay more than 6 percent of their gross income for basic energy expenses such as cooling and heating their homes. Passive design elements like natural ventilation can play a pivotal role in reducing energy consumption. By harnessing ambient energy sources like sunlight and wind, they can create a more comfortable environment at little or no ...

Jellyfish can't do much besides swim, sting, eat, and breed. They don't even have brains. Yet, these simple creatures can easily journey to the depths of the oceans in a way that humans, despite all our sophistication, cannot. But what if humans could have jellyfish explore the oceans on our behalf, reporting back what they find? New research conducted at Caltech aims to make that a reality through the creation of what researchers call biohybrid robotic jellyfish. These creatures, which can be thought of as ocean-going cyborgs, augment jellyfish with electronics that enhance their swimming and a prosthetic ...

Atomic force microscopy, or AFM, is a widely used technique that can quantitatively map material surfaces in three dimensions, but its accuracy is limited by the size of the microscope’s probe. A new AI technique overcomes this limitation and allows microscopes to resolve material features smaller than the probe’s tip. The deep learning algorithm developed by researchers at the University of Illinois Urbana-Champaign is trained to remove the effects of the probe’s width from AFM microscope images. As reported in the journal Nano Letters, the algorithm surpasses other methods in giving the first true three-dimensional ...

FAYETTEVILLE, Ark. — Using a novel research methodology, researchers in the U.S. and Tanzania have identified new recommendations for reducing nutrient deficiency in the East African country. Brandon McFadden, professor of agricultural economics and agribusiness and the Tyson Endowed Chair in Food Policy Economics for the Arkansas Agricultural Experiment Station, said that a key recommendation from the study was for policymakers and public health officials in Tanzania to focus on education about zinc deficiency. “Zinc deficiency is a major health problem worldwide, particularly in developing countries, and a major health consequence is stunted growth ...

New research from the University of Washington shows that condom use has been trending downward among younger gay and bisexual men over the last decade, even when they aren’t taking pre-exposure prophylaxis, or PrEP. The study, published Feb. 27 in AIDS and Behavior, measures changes in sex without condoms among HIV-negative gay and bisexual men who are not taking PrEP. Using data from the 2014-19 cycles of the American Men’s Internet Survey — a web-based survey of cisgender men ages 15 and older who have sex with men (MSM) — researchers found ...

(Santa Barbara, Calif.) — Researchers in the United States and China have discovered a curious link between air pollution and suicide rates that prompts us to reconsider how to approach this issue. China’s efforts to reduce air pollution have prevented 46,000 suicide deaths in the country over just five years, the researchers estimate. The team used weather conditions to tease apart confounding factors affecting pollution and suicide rates, arriving at what they consider to be a truly causal connection. The results, published in Nature Sustainability, unearth air quality as a key factor influencing mental health. Issues ...

By Beth Miller With the U.S. government’s goal to reduce emissions from transportation as part of a net-zero climate goal by 2050, efficient and reliable batteries are a necessity. A collaborative team of researchers led by the McKelvey School of Engineering at Washington University in St. Louis is working toward that goal by developing an energy storage system that would have a much higher energy density than existing systems. With $1.5 million from the U.S. Department of Energy’s Advanced Research Projects Agency-Energy (ARPA-E), Xianglin Li, associate professor of mechanical engineering & materials science, will lead a multi-institutional ...
