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. In the study, Kristen ...

Overall rates of long-term survival following stroke are improving, but Black individuals experience worse long-term outcomes compared to white individuals, according to University of Cincinnati research published online July 15 in Neurology®, the medical journal of the American Academy of Neurology. UC’s David Robinson, MD, corresponding author on the research, said prior studies had examined short-term stroke outcomes of 30 or 60 days, but this time the team looked at survival rates five years past a person’s stroke. “This was ...

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 ...

BOSTON, Mass. (July 15, 2024)—A groundbreaking study conducted at the lab of Beth Stevens, PhD, at Boston Children’s Hospital has revealed that an immune protein impacts neuronal protein synthesis in the aging brain. Previous work from the Stevens lab had uncovered that immune cells in the central nervous system, microglia, help prune synapses in the developing brain by tagging synapses with the immune protein C1q. New research led by Nicole Scott-Hewitt, published in Cell, shows that neurons can also internalize C1q. C1q seems to influence protein production inside neurons by interacting with ribosomal proteins, RNA-binding proteins, and ...

A network of proteins found in the central nervous system could be harnessed to increase the effectiveness and reduce the side effects of popular diabetes and weight-loss drugs, according to new research from the University of Michigan.    The study, appearing today in the Journal of Clinical Investigation, focused on two proteins called melanocortin 3 and melanocortin 4 found primarily on the surface of neurons in the brain that play a central role in regulating feeding behavior and maintaining the body's energy balance.   Melanocortin ...

Advances in 3D printing have enabled many applications across a variety of disciplines, including medicine, manufacturing, and energy. A range of different materials can be used to print both simple foundations and fine details, allowing for the creation of structures with tailored geometries. However, creating structures with micro-scale, precise internal voids and channels still poses challenges. Scaffolds used in tissue engineering, for example, must contain a three-dimensional complex network of conduits that mimic the human vasculature. With traditional additive manufacturing, where the material is deposited layer ...

Philadelphia, July 15, 2024 – Building upon groundbreaking research demonstrating how the SARS-CoV-2 virus disrupts mitochondrial function in multiple organs, researchers from Children’s Hospital of Philadelphia (CHOP) demonstrated that mitochondrially-targeted antioxidants could reduce the effects of the virus while avoiding viral gene mutation resistance, a strategy that may be useful for treating other viruses. The preclinical findings were recently published in the journal Proceedings ...

Climate change is causing the ice masses in Greenland and Antarctica to melt. Water from the polar regions is flowing into the world’s oceans –and especially into the equatorial region. “This means that a shift in mass is taking place, and this is affecting the Earth’s rotation,” explains Benedikt Soja, Professor of Space Geodesy at the Department of Civil, Environmental and Geomatic Engineering at ETH Zurich. “It’s like when a figure skater does a pirouette, first holding her arms close to her body and then stretching ...

“FDG-PET is generally considered as a useful metabolic evaluation tool, while it is also thought to have an emerging role for assessment of systemic therapy response.” BUFFALO, NY- July 15, 2024 – A new research paper was published in Oncotarget's Volume 15 on June 20, 2024, entitled, “Comparison of FDG-PET/CT and CT for evaluation of tumor response to nivolumab plus ipilimumab combination therapy and prognosis prediction in patients with unresectable malignant pleural mesothelioma.” Malignant pleural mesothelioma (MPM) is an aggressive neoplasm and affected ...

A new UBC study published recently in Proceedings of the National Academy of Science (PNAS) has unveiled insights into how microscopic organisms such as marine plankton move through water with different density layers.  Researchers Gwynn Elfring and Vaseem Shaik found that density layers, created by variations in temperature or salinity,  influence the swimming direction and speed of tiny particles navigating a liquid. Pushers and pullers “There are two different types of microscopic swimmers – ...

This paper explores an innovative approach to reducing friction on metallic surfaces – a significant advancement that could have major real-world impacts. The study shows that superlubricity – a state with virtually no friction that was once believed to only be achievable at nanoscale – can now be maintained at macroscale for extended time ...

HOUSTON - (July 15, 2024) -  As parents, teachers and pet owners can attest, rewards play a huge role in shaping behaviors in humans and animals. Rewards – whether as edible treats, gifts, words of appreciation or praise, fame or monetary benefits – act as positive reinforcement for the associated behavior. While this correlation between reward and future choice has been used as a well-established paradigm in neuroscience research for well over a century, not much is known about the neural process underlying it, namely how the brain encodes, ...

Waltham — July 15, 2024 — The strengths of academic psychiatry departments and the fast-growing private telehealth sector are complementary, according to a Perspective article published in Harvard Review of Psychiatry, part of the Lippincott portfolio from Wolters Kluwer. Justin A. Chen, MD, MPH, a psychiatrist at Weill Cornell Medicine in New York City, and colleagues reviewed literature on provision of outpatient mental health care in the United States. They concluded that academic psychiatry departments and telehealth companies could mutually benefit from strategic collaboration.  Academic medical centers struggle to ...

Researchers using NASA’s James Webb Space Telescope have finally confirmed what models have previously predicted: An exoplanet has differences between its eternal morning and eternal evening atmosphere. WASP-39 b, a giant planet with a diameter 1.3 times greater than Jupiter, but similar mass to Saturn that orbits a star about 700 light-years away from Earth, is tidally locked to its parent star. This means it has a constant dayside and a constant nightside—one side of the planet is always exposed to its star, while the other is always shrouded in darkness. Using Webb’s NIRSpec (Near-Infrared ...

AMES, Iowa – As highly pathogenic avian influenza has spread in dairy herds across the U.S., the virus is being detected in raw milk. A new study by a broad team of researchers at Iowa State University’s College of Veterinary Medicine helps explain why. Sialic acid, a sugar molecule found on the surface of some animal cells, acts as a receptor for influenza. Without sialic acid providing an entry point to attach, invade and infect, a flu virus is unlikely to find a potential host hospitable. Before the recent HPAI outbreak ...
