EDMONTON — Researchers have found a link between chemotherapy-induced changes to gut bacteria and the unhealthy weight gain seen in breast cancer patients, pointing the way to potentially help survivors avoid obesity-related illness later in their lives.  In newly published research, a team at the University of Alberta found that the patients treated with chemotherapy lost muscle mass and gained abdominal fat, which has been linked to heart disease, diabetes and even cancer recurrence. The chemo patients also exhibited signs of inflammation and significant changes to the number and variety of bacteria in their guts. “Changes in the bacterial populations ...

ITHACA, N.Y. -- Filmmakers may soon be able to stabilize shaky video, change viewpoints and create freeze-frame, zoom and slow-motion effects – without shooting any new footage – thanks to an algorithm developed by researchers at Cornell University and Google Research. The software, called DynIBar, synthesizes new views using pixel information from the original video, and even works with moving objects and unstable camerawork. The work is a major advance over previous efforts, which ...

CLEVELAND–Case Western Reserve University chemical engineer Rohan Akolkar is leading a research team working to develop a new zero-carbon, electrochemical process to produce iron metal from ore.   If successful, the project could be a first step toward eliminating harmful greenhouse gas emissions by eventually replacing century-old, blast-furnace ironmaking with a new electrolytic-iron production process.   Reducing iron ore to metal is carbon- and energy-intensive, leading to significant carbon-dioxide emissions that drive global warming.   “We don’t use carbon at all in our process, so ...

CLEVELAND—U.S. military veterans who lived in what were once known as “redlined” areas had a higher risk for heart attacks and other cardiovascular issues, according to a new study by researchers at Case Western Reserve University, University Hospitals and the Cleveland VA Medical Center. In the 1930s, the federal government-sponsored Homeowners’ Loan Corp. (HOLC) established maps of U.S. neighborhoods that identified levels of mortgage risk. This practice led to disinvestments and segregation in “redlined” neighborhoods. Judicial rulings--and, later, federal legislation--prohibited such government practices, but research has shown their ...

One of the most powerful psychedelics known, N,N-dimethyltryptamine (DMT) has been described as causing imaginative visuals akin to the dream state. It is typically consumed on its own or in ayahuasca, a ceremonial brew that has been used for spiritual and visionary purposes by indigenous cultures for centuries. Some have expressed that DMT helped address psychological ailments such as depression and addiction, promoting emotional well-being. However, the way that DMT impacts the brain, body and health is largely unknown. A ...

Not all carbon emissions are made for the same reason—they range from more essential purposes like heating a home to nonessential “luxury” activities like leisure travel. However, proposals for the implementations of carbon taxes tend to apply to all emissions at an equal rate. This can give rise to and exacerbate inequalities. A new analysis published on July 11 in the journal One Earth suggests taxing luxury carbon emissions at a higher rate instead; if all 88 countries analyzed in this study adopted the luxury-focused policy, this would achieve 75% of the emissions reduction needed to reach the Paris Agreement’s goal of limiting climate change ...

When an electric vehicle is parked outside, its temperature can swing wildly from day to night and season to season, which can lead to deterioration of the battery. To dampen these fluctuations and extend the battery’s lifespan, researchers have designed an all-season thermal cloak that can cool an electric vehicle by 8°C on a hot day and warm it by 6.8°C at night. The cloak, made predominantly of silica and aluminum, can do so passively without outside energy input and operates without any modification between hot or cold weather. This prototype is described July 11 in the newly launched Device, an application-oriented sister journal ...

WASHINGTON, July 11, 2023 – Compared to artificial tears, or eye drops, human tears are significantly more complex liquids, with a wide range of components including lipids, carbohydrates, proteins, water, and salt. It is this complex mixture that gives tears the perfect thickness and ability to moisturize the eye, a design that is hard to replicate with fewer ingredients. In Physics of Fluids, from AIP Publishing, Vega et al. researched human tears at the micron level to reveal new ways of customizing artificial tears to address individual symptoms of dry eye disease. The detailed insights they gained about the composition and behavior ...

Unborn babies use ‘greedy’ gene from dads to ‘remote-control’ mums into feeding them extra food Fetuses use a copy of a gene inherited from their dad to force their mum to release as much nutrients as possible during pregnancy, Cambridge scientists have discovered. The unborn baby ‘remote controls’ its mother’s metabolism so the two are in a nutritional tug of war. The mother’s body wants the baby to survive but needs to keep enough glucose and fats circulating in her system for her own health, to be able to deliver ...

WASHINGTON, July 11, 2023 – Inspired by the need to safeguard marine animals and promote sustainable solutions within marine environments, an interdisciplinary team of researchers from King Abdullah University of Science and Technology in Saudi Arabia and Sofia University in Bulgaria are delving into the hydrodynamics of buoyant objects at the air-water interface. By studying these dynamics, their goal is to expand the understanding of fluid hydrodynamics and complex surface interactions – and advance fields such as the design and performance of marine engineering systems, buoy systems, and ...

July 11, 2023 (BOSTON) – A new national study, led by researchers at Tufts Medical Center in Boston, has found whole genome sequencing (WGS) to be nearly twice as effective as a targeted gene sequencing test at identifying abnormalities responsible for genetic disorders in newborns and infants. The study, “A Comparative Analysis of Rapid Whole Genomic Sequencing and a Targeted Neonatal Gene Panel in Infants with a Suspected Genetic Disorder: The Genomic Medicine for Ill Neonates and Infants ...

Children who experience racial discrimination are more likely to later have a higher body mass index (BMI) and larger waistline, according to a new study published in JAMA Network Open. The findings illustrate that racial discrimination may be a risk factor for young people developing obesity—above and beyond other socioeconomic factors such as family income.   “Exposure to racial discrimination must be acknowledged as both a social determinant of obesity and a significant contributor to obesity disparities among children and adolescents,” said Adolfo Cuevas, assistant professor of social and behavioral sciences at the NYU School of Global Public Health and the study’s ...

BOSTON – The first large-scale U.S. clinical trial of cytisinicline, led by a Massachusetts General Hospital (MGH) investigator, found the smoking cessation medication to be effective and well tolerated in adults who wished to break their nicotine dependence. In the Phase 3 study published in JAMA, researchers reported that cytisinicline could offer adults who smoke a potential new treatment option. “Cigarette smoking remains the leading preventable cause of death worldwide, yet no new smoking cessation medication has been approved by the U.S. Food and Drug Administration for nearly two decades,” says Nancy Rigotti, MD, director of MGH’s ...

That experiences leave their trace in the connectivity of the brain has been known for a while, but a pioneering study by researchers at the German Center for Neurodegenerative Diseases (DZNE) and TUD Dresden University of Technology now shows how massive these effects really are. The findings in mice provide unprecedented insights into the complexity of large-scale neural networks and brain plasticity. Moreover, they could pave the way for new brain-inspired artificial intelligence methods. The results, based on an innovative “brain-on-chip” technology, are published in the scientific journal Biosensors and Bioelectronics. The Dresden researchers explored ...

BINGHAMTON, N.Y. -- A strange mystic swings a pocket watch back and forth, repeating the phrase “You’re getting sleepy, very sleepy,” giving them absolute command over their subject. That’s not how hypnotism really works, but it’s the way it’s often depicted in pop culture. Even some clinicians and hypnosis educators propagate harmful myths about hypnosis. Steven Jay Lynn, a professor of psychology at Binghamton University, State University of New York, is an expert on hypnosis who has made major contributions to the judicial system ...

(WASHINGTON, July 11, 2023) – As the United States faces a growing obesity epidemic, scientists are taking a closer look at how body weight can affect health outcomes. New research published in Blood Advances highlights the potential association of elevated body mass index (BMI) with inferior outcomes to treatment for acute lymphoblastic leukemia (ALL) in adolescents and young adults (AYAs). This study sheds light on the impact of weight on treatment toxicities and outcomes and calls for further study of the impact of weight on response to different ALL chemotherapy regimens. Obesity is a growing public health threat in the United States, affecting approximately ...

OAK BROOK, Ill. – New CT technology allows for a comprehensive, simultaneous evaluation of lung structure and function, something not possible with standard CT, according to a study published in Radiology, a journal of the Radiological Society of North America (RSNA). Chest CT is the imaging method of choice for analyzing lung disease and tracking changes over time. However, CT studies of lung function and perfusion, or blood flow, require dedicated protocols that cannot be combined. Researchers in Germany and the Netherlands developed a chest imaging protocol that yields ...

Moral values such as purity and loyalty are often linked with hateful language, according to a study. Scholars in the field of Natural Language Processing (NLP) have in recent years focused on improving the automated detection of hate speech so such language can be removed from online spaces. But some scholars have argued that mere detection is not a real solution—that NLP can and should be used to investigate the roots of hateful language. Morteza Dehghani and colleagues conducted three studies of hateful language, looking at speeches and texts written by leaders of the Nazi party between 1933 and 1945, hateful slurs ...
