Word lists are the basis of so much research in so many fields. Researchers at the Complexity Science Hub have now developed an algorithm that can be applied to different languages and can expand word lists significantly better than others.   Many projects start with the creation of a word list. Not only in companies when mind maps are created, but also in all areas of research. Imagine you want to find out on which days people are in a particularly good mood by analyzing Twitter postings. Just looking for the word "happy" wouldn't be enough.  Instead, you would have to use an algorithm that detects all tweets that indicate that someone is happy. "So ...

Yersinia bacteria cause a variety of human and animal diseases, the most notorious being the plague, caused by Yersinia pestis. A relative, Yersinia pseudotuberculosis, causes gastrointestinal illness and is less deadly but naturally infects both mice and humans, making it a useful model for studying its interactions with the immune system. These two pathogens, as well as a third close cousin, Y. enterocolitica, which affects swine and can cause food-borne illness if people consume infected meat, have many traits in common, particularly their knack for interfering with the immune system’s ability to respond to infection. The plague pathogen is blood-borne and transmitted by infected ...

Hydrogen’s potential as a clean fuel could be limited by a chemical reaction in the lower atmosphere, according to research from Princeton University and the National Oceanic and Atmospheric Association. This is because hydrogen gas easily reacts in the atmosphere with the same molecule primarily responsible for breaking down methane, a potent greenhouse gas. If hydrogen emissions exceed a certain threshold, that shared reaction will likely lead to methane accumulating in the atmosphere — with decades-long climate consequences. “Hydrogen is theoretically the fuel of the future,” said Matteo Bertagni, a postdoctoral researcher at the High ...

BOSTON – A type of immune therapy called chimeric antigen receptor (CAR)-T cell therapy has revolutionized the treatment of multiple types of blood cancers but has shown limited efficacy against glioblastoma—the deadliest type of primary brain cancer—and other solid tumors. New research led by investigators at Massachusetts General Hospital (MGH) and published in the Journal for ImmunoTherapy of Cancer March 10, 2023, suggests that drugs that correct abnormalities in a solid tumor’s blood vessels can improve the delivery and function of CAR-T cell therapy. With CAR-T cell therapy, immune cells are taken from a ...

DETROIT – A team of faculty from Wayne State University has discovered new technology that will quickly and easily detect active Mycobacterium tuberculosis (TB) infection antibodies. Their work, “Discovery of Novel Transketolase Epitopes and the Development of IgG-Based Tuberculosis Serodiagnostics,” was published in a recent edition of Microbiology Spectrum, a journal published by the American Society for Microbiology. The team is led by Lobelia Samavati, M.D., professor in the Center for Molecular Medicine and Genetics in the School of Medicine. ...

AMHERST, Mass. – University of Massachusetts Amherst biologist Lynn Adler has won the Mahoney Life Sciences Prize for her research demonstrating that different kinds of wildflowers can have markedly different effects on the health and reproduction rate of bumblebees. “My lab studies the role that flowers play in pollinator health and disease transmission,” says Adler. “Flowers are of course a food source for pollinators, but, in some cases, nectar or pollen from specific plants can be medicinal. However, flowers are also high-traffic areas, and just like with humans, high-traffic areas can be hotspots for disease transmission. We’re tracing how different populations ...

New research from Washington University in St. Louis provides evidence that modern gender norms and biases in Europe have deep historical roots dating back to the Middle Ages and beyond, suggesting that DNA is not the only thing we inherit from our ancestors. The findings — published on March 13, 2023 in the Proceedings of the National Academy of Sciences (PNAS) — highlight why gender norms have remained stubbornly persistent in many parts of the world despite significant strides made by the international ...

Populations of whooper swans grow 30 times faster inside nature reserves, new research shows. Whooper swans commonly spend their winters in the UK and summers in Iceland. In the new study, researchers examined 30 years of data on swans at 22 UK sites – three of which are nature reserves managed by the Wildfowl and Wetlands Trust (WWT). Survival rates were significantly higher at nature reserves, and population growth was so strong that many swans moved to non-protected sites. Based on these findings, the research team – led by the universities of Exeter and Helsinki – project that nature reserves could help double the number ...

The cycling of carbon through the environment is an essential part of life on the planet. Understanding the various sources and reservoirs of carbon is a major focus of Earth science research. Plants and animals use the element for cellular growth. It can be stored in rocks and minerals or in the ocean. Carbon in the form of carbon dioxide can move into the atmosphere, where it contributes to a warming planet. A new study led by Florida State University researchers found that plants and small organisms in Arctic rivers could be responsible for more than half the particulate organic matter flowing to the Arctic Ocean. That’s a significantly ...

NEW YORK, NY (March 13, 2023)--A new study by Columbia University researchers suggests that cholesterol-lowering drugs called statins have the potential to reduce heart disease in people with obstructive sleep apnea regardless of the use of CPAP machines during the night. CPAP (continuous positive airway pressure) therapy improves sleep quality and reduces daytime fatigue in people with obstructive sleep apnea. But based on findings from several recent clinical trials, CPAP does not improve heart health as physicians originally hoped. Alternative ...

New research suggests that around 0.5% of global carbon emissions could be captured during the normal crushing process of rocks commonly used in construction, by crushing them in CO2 gas. The paper ‘Mechanochemical processing of silicate rocks to trap CO2’ published in Nature Sustainability says that almost no additional energy would be required to trap the CO2.  0.5% of global emissions would be the equivalent to planting a forest of mature trees the size of Germany. The materials and construction industry ...

Living in the country, in rural areas, has long been idealized as a pristine place to raise a family. After all, open air and room to run free pose distinct advantages. But new findings from a University of Houston psychology study indicate that Americans who live in more rural areas tend to be more anxious and depressed, as well as less open-minded and more neurotic. The study also revealed those living in the country were not more satisfied with their lives nor did they have more purpose, or meaning in life, than people who lived in urban areas.   The ...

Researchers at University of California San Diego School of Medicine and Moores Cancer Center at UC San Diego Health have identified a strong association between the product of a gene expressed in most cancers, including the most common type of head and neck cancer, and elevated levels of white blood cells that produce antibodies within tumors.   The findings, published in the March 10, 2023 issue of PNAS Nexus, suggest a potential new target and approach for cancer immunotherapies that have thus far produced mixed results for certain head and ...

A population data linkage study using anonymised primary and secondary care health records in Swansea University’s SAIL Databank has revealed that in 2020 and 2021, fewer people in Wales were being diagnosed with long-term conditions than expected. Diagnosis rates increased over the two-year period but for most conditions, they still lagged behind expectations at the end of 2021 implicating a potential backlog of undiagnosed patients who are unlikely to be receiving systematic monitoring and management for their conditions. The study was led by researchers ...

Previous studies of hurricanes have shown general increases in mortality but little has been known about how mortality following hurricane exposure may differ among older adults living with dementia.    Their increased risk could be due to disruption of normal routine, such as access to caregiving, changes in living environment, loss in access to medications, and change in daily routines, said study first author Sue Anne Bell, assistant professor at the U-M School of Nursing.   The analysis focused on risk for mortality among people ...

Cherenkov imaging is a valuable cancer treatment tool that can help doctors track and monitor radiation doses received by tissues during cancer therapy in real time. This imaging technique works by detecting Cherenkov radiation, which is emitted by tissues exposed to high-energy radiation, such as X-rays or electron beams from a linear accelerator. As high-energy charged particles from the incident radiation pass through biological tissue, either as primary or secondary radiation, they interact with the electromagnetic fields of the atoms and molecules in the tissue. These soft collision-type interactions ...

In the United States, low-income, Latino youth are disproportionately affected by obesity with 25.8% of Latino youth aged 2-19 considered to have obesity, which is approximately two times more likely when compared to their non-Latino white counterparts. A higher level of obesity results in an increased risk of cardiometabolic diseases, which are a group of related diseases caused by an unhealthy lifestyle and/or an increased genetic predisposition. A new study by Allison McKay, RDN, department manager for the Department of Nutrition and Food Studies, identified elevated insulin, hemoglobin A1C, triglycerides, and other cardiometabolic ...

Government and political institutions should do more to make citizens feel empowered within marine environment decisions and give them the right to participate, new research shows. Marine Citizenship is the term used for people who get involved in changing how humans use the ocean. It has been investigated as a potential policy tool to engage the public in marine environmental issues through a new study by the University of Exeter and the University of Bristol Law School. Despite efforts to tackle human causes such as overfishing, marine litter, microplastics, pollution, ocean acidity, global warming and climate change, there ...

Unlike other forms of blood cancer, acute myeloid leukemia (AML) cannot currently be treated with CAR-T cell immunotherapy. The reason is that specific molecular targets with which certain immune cells could specifically target AML cells are lacking, which would permit the immune system to attack cancer. Two research teams of Professor Dr. Sebastian Kobold with Dr. Adrian Gottschlich from the Division of Clinical Pharmacology at LMU University Hospital Munich and Dr. Carsten Marr with Moritz Thomas from the Institute of AI for Health at Helmholtz Munich have now ...

A growing body of evidence is showing that the healthy gut microbiome – a community of microorganisms that live together in the gut – influences many aspects of human growth and development, especially during adolescence. While there are many physiologic changes during this time, one of the most outward facing, and sometimes distressing, is the development of acne. Most individuals treat their acne with topical therapies; however, around 25% of adolescents require systemic antibiotics, such as minocycline, to help to alleviate symptoms and clear up the skin. These systemic antibiotic ...

“Selective protection of normal cells may transform therapy of cancer.”  BUFFALO, NY- March 13, 2023 – A new review paper was published in Oncotarget's Volume 14 on March 11, 2023, entitled, “Selective protection of normal cells from chemotherapy, while killing drug-resistant cancer cells.” Cancer therapy is limited by toxicity in normal cells and drug-resistance in cancer cells. In his latest review, Mikhail V. Blagosklonny, M.D., Ph.D., from Roswell Park Comprehensive Cancer Center discusses the theory that cancer resistance to certain therapies can be exploited ...

Insect pests which attack crops have extraordinary powers to develop resistance to greener pesticides and a new way to manage resistance risks is needed, according to analysis by University of Stirling scientists. For more than 70 years, agriculture’s response to pesticide resistance has been to seek new pesticides in an endless race to keep up with evolving pests. Researchers now propose a new way to step off this treadmill as farmers embrace the ongoing green revolution in pest control by switching to biopesticides derived from natural organisms. The evolution of resistance to biopesticides - a crucial tool in ...

Racial minorities in the United States are less likely to receive treatment for prostate cancer and, overall, have worse survival outcomes compared to individuals who are white. Typically, patient-level and physician-level factors have been used to explain the racial and socioeconomic differences in prostate cancer disparities. However, a new study led by investigators from Brigham and Women’s Hospital, a founding member of the Mass General Brigham healthcare system, investigated the role of facilities themselves ...

-With pictures- Scientists have demonstrated in a new study that carbon-based molecules can be much more dynamic than previously thought. When a carbon atom forms four bonds to different groups, the molecule can exist in two mirror image forms. These mirror image forms are vital in medicine because they have different biological activities. Usually, it is impossible to interconvert between these ‘enantiomers’ because to do so would require a bond to be broken, a process that needs too much energy. The researchers ...
