In less than a week’s time, families around the country will be sitting down to tuck into their traditional Christmas dinner. While the festive season is often a time of overindulgence, could parts of a festive banquet actually help improve our health? Experts at Newcastle University, UK, have been researching the different characteristics and compounds of festive trimmings and have found that some of the side-dishes offer significant benefits. Fighting chronic conditions Soggy sprouts should be off the menu say Newcastle researchers – ...

Utilities in the United States have pledged to transition to 100% renewable electricity by 2060, and although state mandates have played a role, it’s the utilities, themselves, that are leading the transition.   “Many people feel the transition on the policy side isn’t going fast enough,” said Matthew Burgess, a CIRES fellow, CU Boulder assistant professor, and co-author of the paper published today in Climatic Change. “But the private sector is moving faster than we thought. A lot has ...

Not all bacteria are created equal. Most are single-celled and tiny, a few ten-thousandths of a centimeter long. But bacteria of the Epulopiscium family are large enough to be seen with the naked eye and 1 million times the volume of their better-known cousins, E. coli. In a study published Dec. 18 in Proceedings of the National Academy of Sciences, researchers from Cornell and Lawrence Berkeley National Laboratory have for the first time described the full genome of one species of the family of giants, which they’ve named Epulopiscium viviparus. “This incredible giant bacterium is unique and interesting ...

Carbon capture and sequestration (CCS), the process of capturing and storing atmospheric carbon dioxide, is one method of reducing the amount of carbon dioxide in the atmosphere in efforts to reduce the impacts of climate change. While CCS is an essential tool in decarbonizing the U.S. economy, there are barriers that exist to the development, approval, and implementation of a geologic sequestration site, as it requires an appropriate geologic formation, as well as an approved injection facility. Recent work from the Carnegie Mellon University Department of Engineering and Public Policy (EPP) estimates the time required to develop, approve, and implement ...

Antibiotic-resistant “superbugs” that can defeat efforts to kill them are an urgent public health crisis, and according to the Centers for Disease Control, more than 2.8 million antibiotic-resistant infections occur each year. Researchers across the world are scrambling to meet the challenge. A collaborative team of researchers led by the University of Massachusetts Amherst and including scientists from the biopharmaceutical company Microbiotix recently announced that they had successfully learned how to sabotage a key piece of machinery that pathogens use to infect their host cells, and have developed a test to identify the next-generation drugs ...

Researchers examining the data on opioids for pain caused by cancer have found surprisingly large gaps in evidence regarding the true benefits of these medicines for cancer pain. The review challenges the commonly held view that opioids are the most powerful pain relievers. The University of Sydney-led review highlights there is no ‘one size fits all’ treatment approach for cancer pain, urging health professionals and patients to carefully weigh up the evidence when deciding on a suitable pain management plan. Opioid pain relievers are the most common treatment for cancer pain management. Many international guidelines including the ...

B cell deficiency is a common condition that can result either from immunosuppressant drugs used to treat autoimmune disease or certain cancers — such as rituximab (RTX) — or from natural immune deficiency. These patients suffer from a weakened immune system that is less effective at combating both viral and bacterial diseases. As B cells are a key type of immune cell that produces antibodies, a deficiency results in a significant decrease in antibody count that can lead to severe disease or death upon infection with SARS-CoV-2. Researchers at the Ragon Institute of Mass General, MIT, and ...

ARLINGTON HEIGHTS, Ill. – (December 18, 2023) — Two new practice parameters from the Joint Task Force for Practice Parameters (JTFPP) offer evidence-based recommendations for the diagnosis and management of anaphylaxis and atopic dermatitis (AD) in pediatric and adult patients. The Joint Task Force is a partnership between the American College of Allergy, Asthma and Immunology (ACAAI) and the American Academy of Allergy, Asthma and Immunology. “Both anaphylaxis and atopic dermatitis are allergic conditions that affect millions of people – in the United States and around the world,” says allergist Jay Lieberman, MD, co-chair of the JTFPP ...

New research suggests that air pollution may contribute to the development or worsening of skin conditions. The work, which is published in Dermatology and Therapy and led by scientists at Massachusetts General Hospital (MGH), a founding member of the Mass General Brigham healthcare system, points to the need to improve air quality to lower the burden of skin disease, especially for vulnerable communities. “We were inspired to investigate the relationship between air pollution and skin inflammation after listening to patients who kept telling us that their skin conditions like eczema were particularly bad, and in some cases ‘worse than ever before,’ this summer,” ...

“[...] murine models proved to be valuable and, in some cases, indispensable for advancing melatonin applications in oncology [...].” BUFFALO, NY- December 18, 2023 – A new research perspective was published in Oncotarget's Volume 14 on December 12, 2023, entitled, “Melatonin and carcinogenesis in mice: the 50th anniversary of relationships.” Fifty years ago, in 1973, Vladimir N. Anisimov and coauthors demonstrated for the first time an inhibitory effect of the pineal ...

New Haven, Conn. — In a new study by researchers at the Yale School of Public Health, two “forever chemicals” spurred cancer cells in the lab to migrate to new positions, an indication that the chemicals could contribute to cancer metastasis in living organisms. The study addressed the group of industrial chemicals called per- and polyfluoroalkyl substances (PFAS). The substances are known as “forever chemicals” because they don’t break down in the environment and can build up in the human body. They have the ability to shed water and resist penetration by oils. They are ...

Survey Highlights: A majority of Americans (51%) say it takes them weeks to feel less stressed after the holidays, with more than a quarter of moms reporting it takes them a month or more to recover. 71% of respondents say that their biggest regret after the holidays is that they did not take the time to relax and enjoy the season. Overall, respondents (63%) claimed that the holiday season is more stressful than tax season. Eating healthy (69%), exercising regularly (64%), and getting enough sleep (56%) are the top three things that respondents have trouble prioritizing during the holiday season. 79% of people surveyed agree that, during the holidays, they are so focused on creating special ...

Public opinion polls are often considered "the will of the people" but a new study on the role of polls in South Korea shows that they may not always be that transparent. "Using polls to gauge what people think about politics is not as simple as it sounds, as there are multiple mediating factors between what people think and how their views may be represented in the media," says co-author Sunmin Kim, an assistant professor of sociology at Dartmouth. "Our research shows more broadly, how in a democracy, measuring what people think or want can be a highly haphazard and unpredictable process based on the ways public opinion poll ...

A team of Brigham researchers analyzed GPT-4’s performance in four clinical decision support scenarios: generating clinical vignettes, diagnostic reasoning, clinical plan generation and subjective patient assessments.  When prompted to generate clinical vignettes for medical education, GPT-4 failed to model the demographic diversity of medical conditions, exaggerating known demographic prevalence differences in 89% of diseases.  When evaluating patient perception, GPT-4 produced significantly different responses by gender or race/ethnicity for 23% of cases.  Large language models (LLMs) like ChatGPT and GPT-4 have the potential to assist in ...

Apes recognize photos of groupmates they haven’t seen for more than 25 years and respond even more enthusiastically to pictures of their friends, a new study finds. The work, which demonstrates the longest-lasting social memory ever documented outside of humans, and underscores how human culture evolved from the common ancestors we share with apes, our closest relatives, was published today in the journal Proceedings of the National Academy of Sciences. “Chimpanzees and bonobos recognize individuals even though they haven’t seen them for ...

EMBARGO LIFTS DEC. 18, 2023, AT 3:00 PM U.S. EASTERN TIME As the world heats up, and the climate shifts, life will migrate, adapt or go extinct. For decades, scientists have deployed a specific method to predict how a species will fare during this time of great change. But according to new research, that method might be producing results that are misleading or wrong. University of Arizona researchers and their team members at the U.S. Forest Service and Brown University found that the method – commonly referred to as space-for-time substitution – failed to accurately predict how a widespread tree of the Western U.S. called the ...

Ancient bricks inscribed with the names of Mesopotamian kings have yielded important insights into a mysterious anomaly in Earth’s magnetic field 3,000 years ago, according to a new study involving UCL researchers. The research, published in the Proceedings of the National Academy of Sciences (PNAS), describes how changes in the Earth’s magnetic field imprinted on iron oxide grains within ancient clay bricks, and how scientists were able to reconstruct these changes from the names of the kings inscribed on the bricks. The team hopes that using this “archaeomagnetism,” which looks for signatures ...

Researchers led by a University of California, Berkeley, comparative psychologist have found that great apes and chimpanzees, our closest living relatives, can recognize groupmates they haven't seen in over two decades — evidence of what’s believed to be the longest-lasting nonhuman memory ever recorded.  The findings also bolster the theory that long-term memory in humans, chimpanzees and bonobos likely comes from our shared common ancestor that lived between 6 million and 9 million years ago. The team used infrared eye-tracking cameras to record where bonobos and chimps gazed when they were shown side-by-side images of other bonobos ...

A study conducted by pre-PhD researcher Pablo S. Valera and recently published in PNAS demonstrates the potential of surface-enhanced Raman spectroscopy (SERS) to explore metabolites secreted by cancer cells in cancer research. The study, which has been led by Ikerbasque Research Professors Luis Liz-Marzán (from CIC biomaGUNE) and Arkaitz Carracedo (of CIC bioGUNE) and in which other researchers from both centers, also members of the Networking Biomedical Research Centre (CIBER), have participated as well, provides valuable information to guide more specific experiments to reveal ...

Myosteatosis, or aging-related fat accumulation in skeletal muscles, is a leading cause of declines in muscle strength and quality of life in elderly adults. Older adults who are sedentary and develop accumulated fat in the skeletal muscle are often prescribed exercise by their doctors to combat the condition. If scientists were to develop a new therapy, such as medications, to combat myosteatosis, they would need to replicate the mechanism by which exercise might reduce fat accumulation in muscles.    Fibro-adipogenic ...

NASA’s James Webb Space Telescope recently trained its sights on unusual and enigmatic Uranus, an ice giant that spins on its side. Webb captured this dynamic world with rings, moons, storms, and other atmospheric features – including a seasonal polar cap. The image expands upon a two-color version released earlier this year, adding additional wavelength coverage for a more detailed look. With its exquisite sensitivity, Webb captured Uranus’ dim inner and outer rings, including the ...

How are memories consolidated during sleep? In 2021, researchers led by Dr. Thomas Schreiner, leader of the Emmy Noether junior research group at LMU’s Department of Psychology, had already shown there was a direct relationship between the emergence of certain sleep-related brain activity patterns and the reactivation of memory contents during sleep. However, it was still unclear whether these rhythms are orchestrated by a central pacemaker. So the researchers joined up with scientists from the Max Planck Institute for Human Development in Berlin and the University of Oxford to reanalyze the data. Their results have identified ...
