WASHINGTON, March 21, 2023 – 3D-printing food could address global challenges in food supply and nutrition. But there are hurdles involved in adapting additive manufacturing to produce edible materials. In Physics of Fluids, from AIP Publishing, University of Ottawa researchers Ezgi Pulatsu and Chibuike Udenigwe identify a range of factors that affect the print quality and shape complexity of food created with additive manufacturing. Accounting for these features can increase food quality, improve control, and speed up printing. Additive manufacturing of food involves designing (3D shapes and their geometric codes), ...

WASHINGTON, March 21, 2023 – Transportation systems in urban settings are vulnerable to a variety of factors including weather, traffic congestion, and special events. Bottlenecks, in particular, can cause major problems and lead to cascading failure of the entire system. Scientists from Fudan University and Shanghai University of Electric Power in China developed a modeling technique to study urban traffic flows and verified it with real-world data from Shanghai. They describe their approach in Chaos, by AIP Publishing, and show that their model can be used to find previously unknown bottlenecks that could ...

Philadelphia, March 21, 2023 – Researchers from Children’s Hospital of Philadelphia (CHOP) have found that adolescents who report strong relationships with their parents have better long-term health outcomes. Study findings, published today in JAMA Network Open, suggest that investments in improving parent–adolescent relationships could help improve general health, mental health and sexual, health while also reducing substance use in young adulthood. Prior research shows that positive ...

About The Study: In this study of 31 million births in the United States from 2011 to 2018, neonatal Down syndrome diagnoses increased more in states that enacted 20-week abortion bans compared with states that did not enact bans. Because these abortion bans were enacted throughout the study period and are known to inhibit choice in patient decision-making, it is possible that the difference in the rates of diagnosis is associated with these policies.  Authors: Sarina R. Chaiken, B.A., and Aaron B. Caughey, M.D., Ph.D., of the Oregon Health & Science University in Portland, is the corresponding author.  To ...

About The Study: This study including 608,000 obstetric discharges found that Black and Hispanic patients experienced higher adjusted odds of postpartum emergency department visits across all hospital types, particularly at safety net hospitals and those disproportionately serving racial and ethnic minority populations. These findings support the urgent need to mitigate structural racism underlying maternal health disparities.  Authors: Michelle P. Lin, M.D., M.P.H., M.S., of Stanford ...

How does the world look like at the smallest scales? This is a question scientists are trying to answer in particle collider experiments like the Large Hadron Collider at CERN in Switzerland. To compare the results of these experiments, theoretical physicists need to provide more and more precise predictions based on our current model for the interactions of fundamental particles, the so called standard model. A key ingredient in these predictions are so called Feynman integrals. Recently, a team of the PRISMA+ Cluster of Excellence at Mainz University, consisting of Dr. Sebastian Pögel, Dr. Xing Wang and Prof. Dr. Stefan Weinzierl developed a method to efficiently ...

COLUMBIA, Mo. — For more than 20 years, Matt Maschmann, an associate professor of mechanical and aerospace engineering at the University of Missouri, has worked with materials that require specialized technology — electron microscopes — to be seen by the human eye. “When we deal with materials interacting on a nanoscale level, we can’t physically see the processes that are occurring, like the charging and discharging of a battery, for instance, without the help of an electron microscope,” Maschmann said. Now, with the support of a two-year, $800,000 grant from the National Science Foundation and an ...

Utrecht, March 21, 2023 - Recent research from University Medical Center Utrecht (UMC Utrecht) shows that our brain declines later than previously thought.

SCOTTSDALE, Ariz. — March 21, 2023 — HonorHealth Research Institute announced today that it is among the first healthcare providers in the U.S., and the first in Arizona, to use an advanced radiation protection system as part of the diagnosis and treatment of heart disease. Modern cardiac catheterization laboratories use multiple X-ray beams from different angles to produce high-quality images of the heart, major arteries and other tissues. These low-level radiation beams enable physicians to guide catheters and other devices during interventional cardiology procedures, which are non-surgical, catheter-based therapies for ...

The cellular glitches underlying a rare genetic disorder called activated PI3K Delta syndrome 2 (APDS2) have been identified by researchers at the Garvan Institute of Medical Research. The disorder is caused by genetic variations that disrupt immune cell signalling through a protein called PI3K. “This study tells us how signalling in the immune system needs to be tightly balanced to make an effective response to infection. Sometimes it’s turned down and you have a problem, and sometimes signalling being turned up can interfere with an immune ...

Bethesda, MD (March 21, 2023) — The American Gastroenterological Association (AGA) has released new clinical guidance to help physicians and patients identify if unexplained digestive symptoms are due to alpha-gal syndrome, a food allergy that is caused by lone star tick bites. The AGA Clinical Practice Update was published today in Gastroenterology. Alpha-gal syndrome is an allergy that causes your body to react to eating meat from mammals and products made from mammals. Symptoms usually start 2-6 hours after eating the mammalian meat or food. Clinicians should consider alpha-gal syndrome in patients ...

Forests, trees and green spaces play a vital role in ensuring a healthy life for all on a global scale. The health benefits of forests and trees, ranging from physical and mental well-being to overall mortality reduction, far outweigh the adverse effects on health. As health threats, such as forest fires, are mainly caused by human activities, urgent action is needed. In order to address health challenges, it is important to recognize the close links between human health and the health of other species, of ecosystems, and of the planet as a whole. Vienna, March, 21, 2023 - The global scientific evidence of the multiple types of benefits ...

The American Society for Biochemistry and Molecular Biology sent recommendations to the U.S. Citizenship and Immigration Services related to the agency’s proposed changes to petition processing fees. The USCIS proposed increasing its filing fees for employment-based visas by up to 2,050%, a measure intended to remedy financial deficits at USCIS and ramp up hiring to improve services. The ASBMB expressed concern about how “the proposed rule is likely to harm the retention of highly skilled foreign-born scientific researchers.” The ...

They published their work on February in Energy Material Advances.   "Constructing an efficient ionic/electronic framework is crucial for the development of high-performance solid-state batteries," said Dr. Chuang Yu, a professor at the State Key Laboratory of Advanced Electromagnetic Engineering and Technology at Huazhong University of Science and Technology. "Currently, the application of solid-state batteries with inorganic electrolytes is challenging because most solid electrolytes have an unsatisfactory low oxidation potential."   According to Dr. Yu, halide electrolytes have been found to be cathode-stable materials with relatively wide electrochemical ...

Eight years ago, the data was sound but only suggestive, the evidence strong but circumstantial. Now, the University of Nebraska–Lincoln’s Karrie Weber and colleagues have experimentally confirmed that nitrate, a compound common in fertilizers and animal waste, can help transport naturally occurring uranium from the underground to groundwater. Their new research backs a 2015 Weber-led study showing that aquifers contaminated with high levels of nitrate — including the High Plains Aquifer residing beneath Nebraska — also contain uranium concentrations far exceeding a threshold set by the Environmental Protection Agency. Uranium concentrations above that EPA threshold ...

Microplastics are tiny plastic particles less than 5 mm in diameter that have emerged as a novel marine environment pollutant. Microplastics usually result from a breakdown of larger plastic debris but can also be generated from plastic microbeads used in personal care products. Over the years, there has been a significant buildup of microplastic pollutants in our oceans, with a recent estimate that the world’s oceans contain over 24.4 trillion pieces of microplastics weighing between 82,000 and 578,000 tons. It is highly likely that ...

Using ESO’s Very Large Telescope (VLT), two teams of astronomers have observed the aftermath of the collision between NASA’s Double Asteroid Redirection Test (DART) spacecraft and the asteroid Dimorphos. The controlled impact was a test of planetary defence, but also gave astronomers a unique opportunity to learn more about the asteroid’s composition from the expelled material. On 26 September 2022 the DART spacecraft collided with the asteroid Dimorphos in a controlled test of our asteroid deflection capabilities. The impact took place 11 million kilometres away ...

WASHINGTON—Women with obesity may share risk for the disease with their daughters, but not their sons, according to a new study published in the Endocrine Society’s Journal of Clinical Endocrinology & Metabolism. Obesity is a common, serious and costly disease affecting nearly half of the adults and 20 percent of children in the United States. It costs an estimated $173 billion in medical care costs. People with obesity are at higher risk of developing diabetes, high blood pressure, heart ...
