Imagine if physicians could capture three-dimensional projections of medical scans, suspending them inside an acrylic cube to create a hand-held reproduction of a patient's heart, brain, kidneys, or other organs. Then, when the visit is done, a quick blast of heat erases the projection and the cube is ready for the next scan. A new report in the journal Chem by researchers at Dartmouth and Southern Methodist University (SMU) outlines a technical breakthrough that could enable such scenarios, and others with widespread utility. The study introduces a technique that uses a specialized ...

Pregnant and postpartum women with depression and anxiety have a slightly better chance of getting psychotherapy these days, a new study finds. And they are paying less of their own money when they do. The changes in care and cost happened mainly after the Affordable Care Act took effect in 2014, and to a lesser extent after the Mental Health Parity and Addiction Equity Act, or MHPAEA, took effect in 2010, the analysis shows. Both laws aimed at reducing insurance-related barriers to mental health care. Even so, only about 10% of women with private insurance ...

About The Study: In this systematic review, universal free school meals were associated with increased meal participation, no or slight improvements in attendance, and decreased obesity prevalence and suspension rates; certainty of evidence was moderate for lunch participation and low or very low for other outcomes. Studies did not report several important outcomes, such as diet quality and food security, suggesting the need for more high-quality research encompassing policy-relevant indicators.  Corresponding Author: To ...

People with celiac disease must navigate everyday life by avoiding gluten, a protein in wheat, rye and barley which can trigger painful symptoms in the gut, impede the absorption of nutrients and raise the risk of other serious long-term issues. The autoimmune disorder affects about 1 per cent of the population. Its rate of occurrence has roughly doubled in the past 25 years, but there is no treatment available. An interdisciplinary  team of medical and engineering researchers centred at Canada’s McMaster University and including colleagues from the US, Australia, and Argentina, has spent the ...

The Three Gorges Region of the Yangtze River (TGR) in China has a unique geographical location, complex geomorphological features, and a fragile and sensitive climate. The Three Gorges Project, as a large-scale comprehensive water conservancy hub project in the region, has not only greatly changed the nature, society and economy of the area, but also brought great benefits and created problems, such as environmental and climatic impacts. Therefore, it is of great importance to conduct climate and environmental monitoring in the region. Recently, a team led by Chen Xianyan, a Professor at ...

In this work, we study the outdoor and indoor photovoltaic performance of LHP-based devices utilizing Spiro-OMeTAD as the hole-transport material with commonly used dopants such as lithium bis(trifluoromethanesulfonyl)imide (Li-TFSI) or without any dopants. We find out that, despite the expected low performance of devices employing undoped Spiro-OMeTAD layer under 1-Sun illumination (up to 7.7% efficiency), the devices achieve up to 25.6% efficiency under 1000 lux illumination, which is comparable to the doped counterpart devices achieving up to 29.7% efficiency. This is mainly due to the major improvement in fill factor when going towards low-light ...

“GT is a fascinating evolutionary phenomenon observed in lower species and humans, albeit with differing impacts and mechanisms.” BUFFALO, NY- August 9, 2024 – A new editorial was published in Oncoscience (Volume 11) on July 13, 2024, entitled, “Unveiling retrotransposon-derived DNA zip code for myeloma cell internalization.” The complex interplay between extracellular genetic material and the tumor's genetic landscape presents a significant challenge in grasping cancer evolution, tumor genetic heterogeneity, and treatment response. Earlier research has revealed the role of circulating tumor DNA (ctDNA) in mediating the gene expression among ...

ZrC has drawn wide attention as an anti-ablation coating material for lightweight C/C composites but is limited by the produced porous and loose ZrO2 film. To address this issue, the second phase is introduced to improve the densification of the formed Zr-X-O film. Such as ZrC-SiC/TaC coating, the produced low-melting-point oxides, SiO2 (Tm=1650 °C), Ta2O5 (Tm=1800 °C) and Zr6Ta2O17 (Tm=1900 °C), helped to form a dense oxides film. However, the high service temperature causes heat accumulation and a large thermal stress gradient on the surface of the coatings, which will result in large local defects and accelerate the failure of the coating. To decrease the ablation heat ...

Along with all the coffee we drink every day, over 6 million tons of spent coffee grounds are produced annually worldwide. Some of these grounds are reused as biofuel but the rest are disposed of in landfills. Over the last decade, research has focused on how to reuse these grounds. The primary focus has been on the polysaccharides from the cellulose and hemicellulose in the ground up coffee bean’s cell walls. Polysaccharides are used in composites, biopolymers, food packaging, construction materials and cellulose nanofibers (CNFs). CNFs specifically, which are cellulose reduced to nanoparticle size, 3 to 5 ...

As the effects of a changing climate and other ecological insults compound, many coral reefs face severe perturbations and a generally poor prognosis for recovery. In an article published in BioScience's new "Perspective and Insight" category, Dr. Peter J. Edmunds of California State University, Northridge, argues for the continued monitoring of coral reefs, even when the seascapes they inhabit are in a significantly degraded state. Drawing from his ongoing 37-year study in the US Virgin Islands, Edmunds argues that "only consistent, rigorous, and detail-oriented ...

The natural world is rich in chemical compounds with remarkable medicinal properties. A notable example is penicillin, discovered by chance from the Penicillium mold. This discovery revolutionized the treatment of bacterial infections and highlighted the potential of natural compounds in medicine. Since then, the identification, isolation, and synthesis of novel bioactive compounds from plants, fungi, and bacteria have become fundamental to drug development. Recently, two groups of naturally occurring bioactive compounds have garnered significant attention: violaceoids A–F ...

New research from the University of Adelaide has shown that glossy black-cockatoos prefer to feed from trees growing in acidic soils. Glossy black-cockatoos are seed-eating birds that feed almost exclusively on the cones of drooping sheoak trees. However, counterintuitively, they select trees that grow on the poorest soils found on ancient sedimentary rocks. “Sheoak trees are three times more likely to be used as feeding trees if they are growing on non-limestone sedimentary rocks,” says Dr Gay Crowley, from the University of Adelaide’s School of Social Sciences. Dr Crowley compared 6,543 feeding records with 23,484 ...

Autistic youth who were born in underserved neighborhoods are more likely to have greater attention deficit hyperactivity disorder (ADHD) symptoms than those born in communities with more resources. This is one finding of a new study led by researchers at the UC Davis MIND Institute.   This is the first time researchers have investigated how neighborhood factors are associated with ADHD in autistic and non-autistic children. The study provides new insights into mental health conditions and has the potential to inform public policy changes to improve health equity. It was published in the journal JCPP Advances. “We found that some neighborhood ...

Content warning: This post contains details of sharing intimate imagery without consent that may be disturbing to some readers. While much attention on sexually explicit “deepfakes” has focused on celebrities, these non-consensual sexual images and videos generated with artificial intelligence harm people both in and out of the limelight. As text-to-image AI models grow more sophisticated and easier to use, the volume of such content is only increasing. The escalating problem led Google to announce last week that it will work to filter out these deepfakes in search results, and the Senate recently passed ...

LOGAN, UTAH, USA -- Utah State University geoscientist Alexis Ault recalls the devastating aftermath of back-to-back 7.8 and 7.6-magnitude earthquakes on Feb. 6, 2023, near the Turkey-Syria border that killed more than 50,000 people and displaced millions. “We witnessed the destruction firsthand, as well as the resilience of the country and population trying to get their footing and rebuild,” says Ault, associate professor in USU’s Department of Geosciences, who traveled to the disaster site about six months after ...

Light is an excellent carrier of information used not only for classical communication technologies but also increasingly for quantum applications such as quantum networking and computing. However, processing light signals is far more complex, compared to working with common electronic signals. An international team of researchers including Dr. Olga Kocharovskaya, a distinguished professor in the Department of Physics and Astronomy at Texas A&M University, has demonstrated a novel way of storing and releasing X-ray pulses at the single photon level — a concept first ...

A new study from UC Davis Health could help to increase the supply of donor kidneys. Researchers have found that transplant patients who receive kidneys infected with the parasite toxoplasma have virtually the same outcomes as those who receive toxoplasma-negative organs. Despite longstanding concerns, those who received kidneys from toxoplasma antibody positive donors (TPDs) had almost identical mortality and rejection rates. The research was published in Transplant International. “Organs from donors who were positive for toxoplasma did ...

Offering patients with concussion a type of brain scan known as diffusion tensor imaging MRI could help identify the one in three people who will experience persistent symptoms that can be life changing, say Cambridge researchers. Around one in 200 people in Europe every year will suffer concussion. In the UK, more than 1 million people attend Emergency Departments annually with a recent head injury. It is the most common form of brain injury worldwide. When a patient in the UK presents at an Emergency Department with head injury, they ...

Experiments conducted by UC Merced researchers find that people who perform good deeds are far more likely to be thought of as religious believers than atheists. Moreover, the psychological bias linking kindness and helpfulness with faith appears to be global in scale. Research on the mental link between moral behavior and religious belief goes back more than a decade. Prior research, however, emphasized the dark side of this equation, with participants asked whether they assumed it was more probable that a serial killer believed in God or was an atheist (people in nations all over the planet thought the latter ...

In September 2023, a megatsunami in remote eastern Greenland sent seismic waves around the world, piquing the interest of the global research community. The event created a week-long oscillating wave in Dickson Fjord, according to a new report in The Seismic Record. Angela Carrillo-Ponce of GFZ German Research Centre for Geoscience and her colleagues identified two distinct signals in the seismic data from the event: one high-energy signal caused by the massive rockslide that generated the tsunami, and one very long-period (VLP) signal that lasted over a week. Their analysis of the VLP signal—which was detected as far as 5000 kilometers away—suggests ...
