Unlike the Higgs boson, discovered at CERN's Large Hadron Collider in 2012 after a 40-year quest, the new particle proposed by these researchers is so heavy that it could not be produced directly even in this collider The University of Granada is among the participants in this major scientific advancement in Theoretical Physics, which could help unravel the mysteries of dark matter Scientists from the University of Granada (UGR) and the Johannes Gutenberg University Mainz (Germany) have recently published a study in which they endeavour to extend the Standard Model of particle physics (the equivalent of 'the periodic table' for particle physics) and answer some of the questions that this model is unable to answer. Such puzzles include: What ...

This study, published recently in the international journal Insects, was conducted by researchers from the University of Granada, the Doñana Biological Station, and the Biomedical Research Networking Centre for Epidemiology and Public Health (CIBERESP) Researchers from the University of Granada (UGR), the Doñana Biological Station (EBD-CSIC), and the Biomedical Research Networking Centre for Epidemiology and Public Health (CIBERESP) have carried out the most comprehensive study to date of the eating patterns of the tiger mosquito (Aedes albopictus) and other invasive species of the same genus in Europe. The results of the study were recently published in the international journal Insects. This research, which reviews ...

With a survival rate of only five years, the most common and aggressive form of primary brain tumor, glioblastoma multiforme, is notoriously hard to treat using current regimens that rely on surgery, radiation, chemotherapy and their combinations. "Two of the major challenges in the treatment of gliomas include poor transport of chemotherapeutics across the blood brain barrier and undesired side effects of these therapeutics on healthy tissues," said Sheereen Majd, assistant professor of biomedical engineering at the University of Houston. "To get enough medicine across the blood brain barrier, a high dosage ...

Insomnia -- trouble falling asleep, staying asleep or waking up too early -- is a common condition in older adults. Sleeplessness can be exacerbated by osteoarthritis, the most common form of arthritis causing joint pain. While there are effective therapies for treating insomnia in older adults, many people cannot get the treatment they need because they live in areas with limited access to health care, either in person or over the internet. With telephones nearly universal among the elderly, however, researchers at the University of Washington and Kaiser Permanente Washington Health Research Institute sought to determine if therapy using only a phone connection ...

CORVALLIS, Ore. - Flavor differences in whiskey can be discerned based solely on the environment in which the barley used to make the whiskey is grown, a new study co-authored by an Oregon State University researcher found. This is first scientific study that found the environmental conditions, or terroir, of where the barley is grown impacts the flavor of whiskey, said Dustin Herb, an author of the study and a courtesy faculty member in the Department of Crop and Soil Science at Oregon State University. "Terroir is increasingly being used to differentiate and market agricultural products, most commonly wine, as consumers grow more interested in the origins of their food," Herb said. "Understanding terroir ...

Slight differences in clinical features can help physicians distinguish between two rare but similar forms of autoimmune brain inflammation in children, a new study by UT Southwestern scientists suggests. The findings, published online in Pediatric Neurology, could provide patients and their families with a better prognosis and the potential to target treatments specific to each condition in the future. About half of all cases of encephalitis - a rare type of brain inflammation that affects about 1 of every 200,000 people in the U.S. each year - can be traced to an infection. For a portion of other cases in which the cause isn't initially clear, researchers have discovered a link with the patients' ...

LEXINGTON, Ky. (Feb. 19, 2021) - After conducting a study to assess the need for cancer education materials in Appalachian Kentucky, members of the University of Kentucky Markey Cancer Center's Appalachian Career Training in Oncology (ACTION) program worked with faculty from the UK College of Education to create a three-part cancer education curriculum for middle and high school teachers in the region. Kentucky is home to the highest rates of cancer incidence and mortality in the country, and that problem is further concentrated in the Appalachian region of the state. Funded by a grant from the National Cancer Institute, ACTION is a two-year program designed to prepare undergraduate and high school students for cancer-focused careers and is open to students who hail ...

WEST LAFAYETTE, Ind. -- Autonomous underwater vehicles have become versatile tools for exploring the seas. But they can be disruptive to the environment or have trouble traveling through confined spaces. Purdue University researchers are studying an alternative: highly maneuverable, low-cost underwater gliders that operate silently. Components and sensors of the glider also can be easily swapped out or added according to a wide range of mission specifications. "Our goal is persistent operation of mobile robots in challenging environments," said Nina Mahmoudian, associate professor of mechanical engineering. "Most underwater robots ...

BOSTON -- Numerous psychiatric studies have documented increased rates of depression and anxiety among those forced to relocate, with sudden moves often affecting individuals' social support and sense of identity and control. As the COVID-19 pandemic spread through the U.S. in March of 2020, universities evacuated students from their campuses, and thousands quickly relocated. Few studies have examined the mental health impact of the sudden disruption. In a new study of 791 undergraduate and graduate students, surveyed between April 9 and August 4, 2020, researchers from Brigham and Women's Hospital, Boston University's School of Social Work, and McLean Hospital revealed that students forced to relocate during the spring were more likely to report COVID-19-related ...

A study of adults in the United States finds that - broadly speaking - the older you are, the more concerned you are about COVID-19, and the more steps you take to reduce your risk from COVID-19. The study suggests that the biggest boost in risk reduction would stem from communication efforts aimed at raising awareness of COVID-19 risks among U.S. adults under the age of 40. "Our study reinforces the idea that different generations perceive the risks associated with COVID-19 very differently," says Yang Cheng, corresponding author of the study and an assistant professor of communication at North Carolina State University. "It also highlights the need to do more to communicate the need for preventive measures ...

Warming temperatures will potentially alter the climate in Alaska so profoundly later this century that the number of thunderstorms will triple, increasing the risks of widespread flash flooding, landslides, and lightning-induced wildfires, new research finds. In a pair of new papers, a research team led by scientists at the Paris Sciences and Letters University and the National Center for Atmospheric Research (NCAR) show that the sea ice around Alaska could largely give way to open water in the warmer months, creating an ample source of moisture for the atmosphere. This moisture, combined with warmer temperatures that can hold more water vapor, would turbocharge summertime storms over Alaska by the end of ...

Researchers from the University of Illinois Chicago have discovered a new gene-editing technique that allows for the programming of sequential cuts -- or edits -- over time. CRISPR is a gene-editing tool that allows scientists to change the DNA sequences in cells and sometimes add a desired sequence or genes. CRISPR uses an enzyme called Cas9 that acts like scissors to make a cut precisely at a desired location in the DNA. Once a cut is made, the ways in which cells repair the DNA break can be influenced to result in different changes or edits to the DNA sequence. The discovery of the gene-editing capabilities ...

Redirection of lymphocytes, via T-cell bispecific antibodies (TCBs) and chimeric antigen receptors (CARs), is already approved to treat some hematologic malignancies. In solid tumors these immune-based strategies continue to fail. Research led by Joaquín Arribas, co-Program Director of Preclinical and Translational Research at VHIO, has now shown how HER2 breast cancer cells adopt a strategy to resist clearance by redirected lymphocytes. Findings evidence that the disruption of interferon-gamma signaling confers resistance to these immunotherapies and promotes disease ...

In a new study led by Yale Cancer Center, researchers demonstrate sex hormones and insulin growth factors are associated with recurrence risk of endometrial cancer. The findings suggest endocrine-targeted therapies and an assessment of biomarkers in hormone and insulin signaling pathways may be useful in the prevention and treatment of endometrial cancer recurrence. The study is a collaboration with researchers at the University of Hawaii and The International Agency for Research on Cancer (IARC) and is published online today in the journal Cancer Epidemiology Biomarkers and Prevention. "These findings are very ...

WASHINGTON, February 23, 2021 -- One of the most performed medical diagnostic tests to ascertain the health of patients is a complete blood count, which typically includes an estimate of the hemoglobin concentration. The hemoglobin level in the blood is an important biochemical parameter that can indicate a host of medical conditions including anemia, polycythemia, and pulmonary fibrosis. In AIP Advances, by AIP Publishing, researchers from SigTuple Technologies and the Indian Institute of Science describe a new AI-powered imaging-based tool to estimate hemoglobin levels. The setup was developed in conjunction with a microfluidic chip and ...

WASHINGTON, February 23, 2021 -- COVID-19 can spread from asymptomatic but infected people through small aerosol droplets in their exhaled breath. Most studies of the flow of exhaled air have focused on coughing or sneezing, which can send aerosols flying long distances. However, speaking while near one another is also risky since the virus can be ejected by merely talking. In Physics of Fluids, by AIP Publishing, scientists in Japan use smoke and laser light to study the flow of expelled breath near and around two people conversing in various relative postures commonly found in the service industry, such as in hair salons, medical exam rooms, or long-term care facilities. ...

WASHINGTON, February 23, 2021 -- As one of the leading sources of clean and renewable energy, global wind power capacity has increased more than fivefold over the past decade, leading to larger turbines and pushing wind technology to its limits. "These much larger turbines are operating in very different atmospheric layers than smaller turbines used 5-10 years ago," said Srinidhi Gadde, one of the authors of a paper in the Journal of Renewable and Sustainable Energy, from AIP Publishing, that examines the impacts of turbine height. "At these scales, local meteorology and extreme shear events, which frequently occur, can impact ...

The plant that encourages kissing at Christmas is in fact a parasite, and new research reveals mistletoe has an unusual feeding strategy. Like other plants, mistletoe is capable of using sunlight to create its own food, a process called photosynthesis. However, it prefers to siphon water and nutrients from other trees and shrubs, using "false roots" to invade its hosts. "Plants are autotrophic, they make their own food. Humans are heterotrophic, we eat it," explained UC Riverside plant-insect ecologist Paul Nabity. "Mistletoe are mostly heterotrophic, but they can switch if they want to." Nabity's team found when two mistletoes invade the same tree, they increase photosynthesis to get the nutrients they need, essentially sharing the ...

Kittens could be the model for understanding infectious, sometimes deadly, diarrheal disease in both animals and children, according to new research from North Carolina State University. Diarrheagenic Escherichia coli (DEC) bacteria cause lethal diarrheal disease in children worldwide, killing up to 120,000 children under the age of five annually. Atypical enteropathic Escherichia coli (aEPEC) are a form of DEC increasingly associated with diarrheal disease in humans and in kittens. "We were looking for causes of infectious diarrhea in kittens, which has a high mortality rate, and came across this pathogen," says Jody Gookin, FluoroScience Distinguished Professor in Veterinary Scholars Research Education at NC State and corresponding ...

Building upon previous research, an international team led by scientists at University of California San Diego School of Medicine, has validated a more inclusive and comprehensive genetic tool for predicting age of onset of aggressive prostate cancer, a disease that killed more than 33,000 American men in 2020. Reporting in the February 23, 2021 online edition of Nature Communications, the researchers describe the performance of a polygenic hazard score (PHS) -- a mathematical estimate of an individuals' age-specific genetic risk for developing a disease -- in a multi-ethnic patient population. "Genetic tools to predict a man's lifetime risk of prostate cancer might allow us to target cancer screening efforts to the men who are most likely to need it. We are ...

MINNEAPOLIS/ST.PAUL (02/23/2021) -- University of Minnesota Medical School researchers have developed two new rapid diagnostic tests for COVID-19 - one to detect COVID-19 variants and one to help differentiate with other illnesses that have COVID-19-like symptoms. The findings were recently published in the journal Bioengineering. Although many people are hopeful about COVID-19 vaccines, widespread vaccine distribution isn't predicted to be available until several months from now. Until that happens, the ability to diagnose COVID-19 quickly and accurately is crucial to help minimize loss of life and ...

Shipping traffic can be a major source of tiny plastic particles floating in the sea, especially out in the open ocean. In a paper published in the scientific journal Environmental Science & Technology, a team of German environmental geochemists based at the University of Oldenburg's Institute of Chemistry and Biology of the Marine Environment and led by Dr Barbara Scholz-Boettcher for the first time provides an overview of microplastics mass distribution in the North Sea. The scientists found that most of the plastic particles in water samples taken from the German Bight, an area in the south-eastern corner of the North Sea which encompasses some of the world's busiest shipping lanes, originate from binders used in marine paints. "Our hypothesis is that ships leave ...
