If a man and a woman each suffer a heart attack, you may assume the symptoms and diagnoses should be the same. That’s not always the case. While men are more likely to show the more “typical” signs of a heart attack — chest pains, shortness of breath — women are more likely to experience pain in their necks or symptoms that feel like heartburn or nausea. An angiogram that shows a blockage in male blood vessels may not show occlusion in a woman’s smaller vessels, and these differences can lead ...

Investigators at the UCLA Health Jonsson Comprehensive Cancer Center have uncovered new details about the role of a protein called interferon regulatory factor (IRF1) in cancer progression and treatment response, offering new insight that can potentially help improve the effectiveness of cancer immunotherapy.  The study, published in Cell Reports, reveals how IRF1 can both hinder and help the body's immune response to tumors, depending upon which cells the protein is found in.  “We know IRF1 plays ...

Friends of young people who self-harm or have suicidal thoughts may need additional support to prevent negative outcomes on their own mental wellbeing, in addition to the support needed by young people who self-harm. While much research rightly focuses on young people at risk and their families, friendships are rarely considered in research into self-harm, according to a new study from experts at the University of Birmingham. In an extensive literature review, the team set out to draw together all the research in this area to reach a better understanding of common themes around friendship and self-harm ...

Researchers at Queen Mary University of London have found that children living in areas with high levels of deprivation are three times more likely to have severe tooth decay that requires a dental extraction in hospital, compared with children living in more affluent areas. The findings highlight an urgent need for equitable access to preventive dentistry. In the study, published today (16 July 2024) in BMJ Public Health, researchers analysed de-identified GP and hospital records for 600,000 children ...

FOR IMMEDIATE RELEASE Monday, July 15, 2024 Contact: Jillian McKoy, jpmckoy@bu.edu Michael Saunders, msaunder@bu.edu ## Lowering Systolic Blood Pressure below 120 mmHg May Reduce Dementia Risk Among Black, Latino Populations A new study suggests that reducing systolic blood pressure below the clinically safe threshold of 120 mmHg over time may produce slight health-protective benefits against late-life dementia and help reduce racial and ethnic disparities in both hypertension and hypertension control.  Hypertension is one of the most modifiable risk factors for dementia, but most research on dementia risk reduction through blood ...

AUSTIN, Texas — On Prime Day, Amazon shoppers will be able to browse over 600 million products. They may not be aware that most of those listings are from non-Amazon sellers, who account for 60% of sales on the platform. Most are small- and medium-sized businesses: bookstores selling used hardbacks, toymakers selling original goods, and distributors unloading clothes. What shoppers also don’t see is the choice that the platform and the seller make about how to interact. Is it better ...

By Jake Siegel SEATTLE, WASH.—July 15, 2024—How do neurons react to magic mushrooms? What happens in the brain when we see motion, or when we recognize grain patterns in a piece of wood? How do our brains track the subtle changes in our friends’ appearances over time?  The Allen Institute has launched four projects to investigate these questions through OpenScope, a shared neuroscience observatory. Just as astronomers use a few well-equipped observatories to study the universe, the OpenScope program lets neuroscientists worldwide propose and direct experiments on the Allen Brain Observatory pipeline. ...

There’s a frustrating fact about today’s immunotherapies for cancer. While sometimes they work beautifully — completely eliminating or greatly reducing cancer in particular patients — other times they don’t work at all. It’s a mystery. Scientists have posed several hypotheses to explain the disparity. Perhaps it’s the number of mutations present in a tumor, with more mutations leading to better responses. Or maybe it’s the tissue environment surrounding the tumor, with some environments supporting and others suppressing effective immune responses. But so far, none of these ...

Ventures that pursue both commercial and social value creation have grown in popularity in recent years, but a new study published in the Strategic Entrepreneurship Journal better defines four distinct types of social ventures. By training a business model lens on these social good ventures, the study offers insight on how the model choices impact a firm's value creation and value capture potential. “Despite the popularity of the term ‘social entrepreneurship,’ not much was known about the business model of such companies yet,” says study co-author Lien De Cuyper of ...

UNIVERSITY PARK, Pa. — American diets may have gotten healthier and more diverse in the months following the start of the COVID-19 pandemic, according to a new study led by Penn State researchers.

UNIVERSITY PARK, Pa. — Rechargeable solid-state lithium batteries are an emerging technology that could someday power cell phones and laptops for days with a single charge. Offering significantly enhanced energy density, they are a safer alternative to the flammable lithium-ion batteries currently used in consumer electronics — but they are not environmentally friendly. Current recycling methods focus on the limited recovery of metals contained within the cathodes, while everything else goes to waste.   A team of Penn State researchers may have solved this issue. Led by Enrique Gomez, interim associate dean for equity and inclusion and professor of chemical engineering ...

UNIVERSITY PARK, Pa. — Biodegradable electronics allow for medical devices — such as drug delivery systems, pacemakers or neural implants — to safely degrade into materials that are absorbed by the body after they are no longer needed. But if the water-soluble devices degrade too quickly, they cannot accomplish their purpose. Now, researchers have developed the ability to control the dissolve rate of these biodegradable electronics by experimenting with dissolvable elements, like inorganic fillers and polymers, that encapsulate the device. The team, led by Huanyu “Larry” Cheng, the James L. Henderson, Jr. Memorial Associate Professor ...

URBANA, Ill. – Raw poultry is one of the main causes of Salmonella poisoning, which affects thousands of people in the U.S. every year. A new study from the University of Illinois Urbana-Champaign shows that few products with high levels of very virulent Salmonella strains are responsible for most of the illnesses from raw chicken parts. The researchers suggest regulation efforts should focus on detecting and preventing those types of high-risk contamination. “Over the last 20 years, the poultry industry has done a really good job of lowering the frequency of Salmonella in poultry. However, the number of people ...

By Maddie Johnson University of Arkansas System Division of Agriculture Arkansas Agricultural Experiment Station FAYETTEVILLE, Ark. — While half the global population relies on rice as a staple, about 15 percent of rice produced each year is contaminated by potentially fatal aflatoxins. Seeing this threaten lives in her home country of Kenya prompted a graduate research assistant to focus on eradicating the risk through safer storage methods. Faith Ouma, a Ph.D. student in the food science department at the University of Arkansas, was the lead author of “Investigating safe storage conditions to mitigate aflatoxin contamination in rice.” It was published ...

Narcissistic CEOs that also serve as chair of the board are adept at controlling how their boards of directors focus their attention, giving the CEO the ability to get their way. A new study published in the Strategic Management Journal found that by driving board discussions about risk-taking to hold a positive tone, narcissistic CEOs can allocate more resources toward risk-taking strategies. The findings deepen our understanding of how CEO behavior and personality types can drive risk management strategies. The research team — Christopher S. Tuggle of the University of Central Arkansas, Cameron J. Borgholthaus of the University of Wyoming, Peter D. Harms of the University of Alabama, ...

Sickle cell disease is the most common inherited red blood cell disorder in the United States and can lead to health problems including organ dysfunction, acute chest syndrome and strokes over a patient’s lifespan. According to a new study, individuals living with sickle cell disease who experience a delay of more than six months after transferring from pediatric to adult care are twice as likely to be hospitalized compared to those who transition in less than two months.

CLEVELAND—The evolution of resistance to diseases, from infectious illnesses to cancers, poses a formidable challenge. Despite the expectation that resistance-conferring mutations would dwindle in the absence of treatment due to a reduced growth rate, preexisting resistance is pervasive across diseases that evolve—like cancer and pathogens—defying conventional wisdom. In cancer, it is well known that small numbers of drug-resistant cells likely exist in tumors even before they’re treated. In something of a paradox, before treatment, these mutants have been repeatedly shown to have lower fitness than the surrounding ancestor cells from which they arose. It leads ...
