Researchers have developed a new method for 3D printing metal that could help reduce costs and make more efficient use of resources. The method, developed by a research team led by the University of Cambridge, allows structural modifications to be ‘programmed’ into metal alloys during 3D printing, fine-tuning their properties without the ‘heating and beating’ process that’s been in use for thousands of years. The new 3D printing method combines the best qualities of both worlds: the complex shapes that 3D printing makes possible, and the ability to engineer ...

PULLMAN, Wash. – A few words of body appreciation can help counter the negative impact of viewing objectified images of female fitness influencers, according to a Washington State University study. While fitness influencers say they want to inspire good physical health, research has found that their social media posts often inspire negative mental health, especially among younger women. The WSU experimental study, published in the journal Health Communication, revealed that the negative impact ...

For immediate release on Oct. 30, 2023 at 5 a.m. ET   Cardiovascular-related deaths due to extreme heat are expected to increase between 2036 and 2065 in the United States, according to a study supported by the National Institutes of Health. The researchers, whose work is published in Circulation, predict that adults ages 65 and older and Black adults will likely be disproportionately affected.   While extreme heat currently accounts for less than 1% of cardiovascular-related deaths, the modeling analysis predicted this will change because of a projected rise in summer ...

Research Highlights: Cardiovascular deaths from extreme heat in the United States are projected to increase by 162% by the middle of the century, based on a hypothetical scenario where currently proposed U.S. policies to reduce greenhouse gas emissions have been successfully implemented. A more dire scenario forecasts cardiovascular deaths from extreme heat could increase by 233% in the next 13-47 years if there are only minimal efforts to reduce emissions. The percentage increase in deaths ...

PHILADELPHIA— The number of heat related cardiovascular deaths in the United States will increase over the next four decades, according to a new analysis from the Perelman School of Medicine at the University of Pennsylvania. Extreme heat can impact heart health in many ways, including increased heart rate, changes in blood pressure, and increased inflammation. Left untreated, these issues can be deadly. The findings, published today in Circulation, also indicate that older adults and Black adults will experience greater increases in excess cardiovascular deaths due to extreme heat. “As global temperatures rise, analyzing how demographic and environmental trends ...

In Western cultures, adolescence is often viewed as a time of rebellion and irresponsibility. A new article published in the journal Child Development Perspectives synthesized recent research on stereotypes of adolescence using an interdisciplinary approach which integrates developmental psychology, cultural psychology, and neuroscience.  The findings highlight the importance of avoiding the “one-size fits-all” assumptions about teen stereotypes across different cultures. In particular, the research ...

Among those trained, who included nurses, CEOs, academics and corrections officers, post-survey scores increased ...

People have used self-portraits to communicate information about themselves for centuries — and digital cameras make it easier to share a self-portrait than ever before. But even though selfies are now almost ubiquitous, we don’t understand how people use them to communicate. So scientists from the University of Bamberg set out to investigate the semantics of selfies. “Although the term ‘selfies’ is now celebrating its 21st birthday, and although selfies are known in art history for nearly 200 years in photography and more than 500 years in paintings, we still lack a clear classification of the different types of selfies,” ...

Imagine a world without powders. It may sound exaggerated, but our daily lives are intricately connected to powders in various ways from foods, pharmaceuticals, cosmetics to batteries, ceramics, etc. In all these industries, powder mixing is an important unit operation where different types of powders are mixed to achieve uniformity. However, it can be difficult to predict what conditions are optimal to achieve the desired uniformity as the process often relies on trial and error as well as engineers’ expertise. Numerical ...

About 80% of residents in the Lower Mainland, British Columbia, had been infected with SARS-CoV-2 by July 2023 and were at low risk for severe outcomes, but almost half of the oldest adults remained uninfected and were at highest risk of hospitalization and death due to COVID-19, according to a new study published in CMAJ (Canadian Medical Association Journal) https://www.cmaj.ca/lookup/doi/10.1503/cmaj.230721. The findings underscore the need to continue prioritizing older adults for COVID-19 vaccination. "First-ever SARS-CoV-2 infections among older adults may still contribute substantial COVID-19 burden, reinforcing ...

The research, published recently in Marine Pollution Bulletin, delves into the critical interplay between plastic pollution and the introduction of non-indigenous organisms into Indian waters. In recent years, the surge in anthropogenic litter in the ocean has provided an extensive array of substrates for marine ...

Tokyo, Japan – Researchers from Tokyo Metropolitan University have used fruit flies to study how daily eating patterns are regulated. They found that the quasimodo (qsm) gene helped sync feeding to light/dark cycles, but not in constant darkness: instead, the genes clock (clk) and cycle (cyc) keep eating/fasting cycles, while other “clocks” in nerve cells help sync it to days. Deciphering the molecular mechanism behind eating cycles helps us understand animal behavior, including our own. Many members of the animal kingdom eat at roughly the same times each day. This is born out of the need to adapt to aspects of the environment, including ...

Cedars-Sinai Cancer investigators have found that Black men respond as well as white men to systemic therapies for advanced prostate cancer when access to quality healthcare is equal, regardless of socioeconomic status. Their study, published today in the peer-reviewed Journal of Clinical Oncology, counters previous research suggesting that Black men receiving these therapies—which include hormone therapy, chemotherapy and immunotherapy—fare worse than white men do. “We believe this is the most comprehensive look at this issue to date, and our findings suggest that, under the right conditions, Black men with metastatic ...

University of Maryland researchers studying how lithium batteries fail have developed a new technology that could enable next-generation electric vehicles (EVs) and other devices that are less prone to battery fires while increasing energy storage. The innovative method, presented in a paper published Wednesday in the journal Nature, suppresses the growth of lithium dendrites—damaging branch-like structures that develop inside so-called all-solid-state lithium batteries, preventing firms from broadly commercializing the promising technology. But this new design for a battery “interlayer,” led by Department of Chemical and Biomolecular Engineering ...

They explored the impact of spatial coherence and turbulence on holographic ...

DALLAS, October 27, 2023 — Approximately 50 million people in the United States are at higher risk for heart disease and/or stroke because they lack the most basic needs — healthy food, clean air and drinking water, quality education, employment, housing and access to health care. Historically, people of color -- including Black and Hispanic/Latino people, are at even higher risk of cardiovascular disease (CVD) for these same reasons. Through the American Heart Association’s 2023 EmPOWERED to Serve Business Accelerator™, three local social entrepreneurs ...

UNIVERSITY PARK, Pa. — The most lethal feature of any cancer is metastasis, the spread of cancer cells throughout the body. New research led by Penn State reveals for the first time the mechanics behind how breast cancer cells may invade healthy tissues. The discovery, showing that a motor protein called dynein powers the movement of cancer cells in soft tissue models, offers new clinical targets against metastasis and has the potential to fundamentally change how cancer is treated. “This discovery marks a paradigm shift in many ways,” said Erdem Tabdanov, assistant professor of pharmacology at Penn State and a lead co-corresponding author on the study, recently published ...

Two-thousand years ago, forts were constructed by the Roman Empire across the northern Fertile Crescent, spanning from what is now western Syria to northwestern Iraq. In the 1920s, 116 forts were documented in the region by Father Antoine Poidebard, who conducted one of the world's first aerial surveys using a WWI-era biplane. Poidebard reported that the forts were constructed from north to south to establish an eastern boundary of the Roman Empire. A new Dartmouth study analyzing declassified Cold War satellite ...
