VANCOUVER, Wash. --People dreaming of travel post-COVID-19 now have some scientific data to support their wanderlust. A new study in the journal of Tourism Analysis shows frequent travelers are happier with their lives than people who don't travel at all. Chun-Chu (Bamboo) Chen, an assistant professor in the School of Hospitality Business Management at Washington State University, conducted a survey to find out why some individuals travel more frequently than others and whether or not travel and tourism experiences have a prolonged effect on happiness and wellness. The results of his analysis show individuals who pay more attention to tourism-related information and frequently discuss their travel plans ...

San Antonio, Texas (January 4, 2020) - Scientists at Texas Biomedical Research Institute (Texas Biomed) and Southwest National Primate Research Center (SNPRC) published their findings regarding a comprehensive animal model study of SARS-CoV-2 in the peer-reviewed journal Nature Microbiology. These findings were originally posted online in BioRxiv in June of 2020. The study evaluated three nonhuman primate (NHP) species (Indian rhesus macaques, African baboons and new-world origin common marmosets) and young and old animals, to determine susceptibility to the SARS-CoV-2 virus and the development of COVID-19 disease. Over the course of the study, the macaque and baboon ...

TAMPA, Fla (Jan 4, 2021) -- Despite the progress made in managing asthma and chronic obstructive pulmonary disease (COPD), poorly controlled symptoms for both respiratory diseases can lead to severe shortness of breath, hospitalizations or even death. "Only about 50 percent of asthmatics, and an even lower percentage of people with COPD, achieve adequate control of lung inflammation and airway constriction with currently available medications," said END ...

There has been frequent occurrence of red tide in coastal waters around Korea where the sea turns red. Red tide is a phenomenon in which phytoplankton proliferate as nutrient or sewage flow into seawater, making it appear red. This not only causes damage to the fisheries industry but also affects the marine ecosystem. Professor Kitack Lee and Ph.D. candidate Ji-Young Moon (first author) of POSTECH's Division of Environmental Science and Engineering have confirmed that the inflow of nitrogen pollutants since the 1980s has disturbed the nutrient balance in the northeast Asian waters and is changing the species of phytoplankton responsible for red tide. The team also found that the ...

A team of researchers from the National University of Singapore (NUS) has created a novel film that is very effective in evaporating sweat from our skin to keep us cool and comfortable when we exercise, and the moisture harvested from human sweat can be used to power wearable electronic devices such as watches, fitness trackers, and more. Sweating is a natural process for our body to reduce thermal stress. "Sweat is mostly composed of water. When water is evaporated from the skin surface, it lowers the skin temperature and we feel cooler. In our new invention, we created a novel film that is extremely effective in evaporating ...

Real-life applications like magnetometry or quantum gyroscope typically involve precise measurement on multiple parameters. How to achieve the ultimate precision limits simultaneously is a long sought-after grail in the field. It is widely believed that the ultimate precision limits for all parameters cannot be achieved simultaneously, since generators of different parameters are generally non-commuting, which induces the trade-offs among the precisions. Yet such trade-offs are escaped from by the group of Prof. LI Chuanfeng and Prof. XIANG Guoyong from Key Laboratory of Quantum Information at University of Science and ...

Researchers have found a novel way to identify heat-stressed corals, which could help scientists pinpoint the coral species that need protection from warming ocean waters linked to climate change, according to a Rutgers-led study. "This is similar to a blood test to assess human health," said senior author Debashish Bhattacharya, a Distinguished Professor in the Department of Biochemistry and Microbiology in the School of Environmental and Biological Sciences at Rutgers University-New Brunswick. "We can assess coral health by measuring the metabolites (chemicals created for metabolism) they produce and, ultimately, identify the best interventions to ensure reef health. Coral bleaching from warming ...

DALLAS, Jan. 4, 2021 -- Smoking traditional cigarettes in addition to using e-cigarettes results in harmful health effects similar to smoking cigarettes exclusively, according to new research published today in the American Heart Association's flagship journal Circulation. Smoking, a well-known link to cardiovascular disease and death, appears to be on the decline. While the use of e-cigarettes, known as vaping, is increasingly popular, there has been limited research on the impact of vaping on the body. In a large data analysis of more than 7,100 U.S. adults ages 18 and older, researchers studied the association of cigarette smoking and e-cigarette use with inflammation and oxidative stress as biomarkers. Inflammation and ...

To effectively combat an infection, the body first has to sense it's been invaded, then the affected tissue must send out signals to corral resources to fight the intruder. Knowing more about these early stages of pathogen recognition and response may provide scientists with crucial clues when it comes to preventing infections or treating inflammatory diseases resulting from overactive immunity. That was the intent behind a new study, led by researchers at the University of Pennsylvania School of Veterinary Medicine, examining infection with the parasite Cryptosporidium. ...

To control mosquito populations and prevent them from transmitting diseases such as malaria, many researchers are pursuing strategies in mosquito genetic engineering. A new Texas A&M AgriLife Research project aims to enable temporary "test runs" of proposed genetic changes in mosquitoes, after which the changes remove themselves from the mosquitoes' genetic code. The project's first results were published on Dec. 28 in Philosophical Transactions of the Royal Society B, titled "Making gene drive biodegradable." Zach ...

Our understanding of biological proteins does not always correlate with how common or important they are. Half of all proteins, molecules that play an integral role in cell processes, are intrinsically disordered, which means many of the standard techniques for probing biomolecules don't work on them. Now researchers at Kanazawa University in Japan have shown that their home-grown high-speed atomic force microscopy technology can provide information not just on the structures of these proteins but also their dynamics. Understanding how a protein is put together provides valuable clues to its functions. ...

DNA (deoxyribonucleic acid) is the basis of life on earth. The function of DNA is to store all the genetic information, which an organism needs to develop, function and reproduce. It is essentially a biological instruction manual found in every cell. Biochemists at the University of Münster have now developed a strategy for controlling the biological functions of DNA with the aid of light. This enables researchers to better understand and control the different processes which take place in the cell - for example epigenetics, the key chemical change and regulatory lever in DNA. The ...

The method produces spheres that have good capacity for carbon capture, and it works effectively at a large scale. Carbon spheres range in size from nanometers to micrometers. Over the past decade they have begun to play an important role in areas such as energy storage and conversion, catalysis, gas adsorption and storage, drug and enzyme delivery, and water treatment. They are also at the heart of carbon capture technology, ...

Researchers at the University of Turku have discovered what type of neural mechanisms are the basis for emotional responses to music. Altogether 102 research subjects listened to music that evokes emotions while their brain function was scanned with functional magnetic resonance imaging (fMRI). The study was carried out in the national PET Centre. The researchers used a machine learning algorithm to map which brain regions are activated when the different music-induced emotions are separated from each other. - Based on the activation of the auditory and motor cortex, we were able to accurately predict whether the research subject was listening ...

In a series of commissions awarded by the Federal Joint Committee (G-BA) to the Institute for Quality and Efficiency in Health Care (IQWiG), the question is whether for certain surgical procedures, a correlation can be shown between the volume of services provided per hospital and the quality of treatment results. IQWiG's rapid report on heart transplantations is now available. According to the findings, a positive correlation can be inferred between the volume of services and the quality of treatment results for heart transplantations in adults: In hospitals with larger case volumes, fewer of the transplanted patients die, both in timely association with the intervention ...

Quantum computer: One of the obstacles for progress in the quest for a working quantum computer has been that the working devices that go into a quantum computer and perform the actual calculations, the qubits, have hitherto been made by universities and in small numbers. But in recent years, a pan-European collaboration, in partnership with French microelectronics leader CEA-Leti, has been exploring everyday transistors--that are present in billions in all our mobile phones--for their use as qubits. The French company Leti makes giant ...

Imaging techniques enable a detailed look inside an organism. But interpreting the data is time-consuming and requires a great deal of experience. Artificial neural networks open up new possibilities: They require just seconds to interpret whole-body scans of mice and to segment and depict the organs in colors, instead of in various shades of gray. This facilitates the analysis considerably. How big is the liver? Does it change if medication is taken? Is the kidney inflamed? Is there a tumor in the brain and did metastases already develop? ...

December 28, 2020 - Platelet-rich plasma (PRP) treatment, which involves injecting a small amount of a patient's own blood to release various growth factors from platelets, continues to increase in popularity. The American Society of Plastic Surgeons has tracked the procedure since 2015 and reports a 25 percent increase in cosmetic PRP use in the last four years. That increase in popularity could in part trace back to celebrities extolling the procedure's cosmetic benefits. Yet with so much information coming from so many different sources about the treatment's ...
