Rallying for a better badminton birdie

2024-01-09

WASHINGTON, Jan. 9, 2024 – Badminton traces its roots back more than a millennium, but the modern version of the racket game originated in the late 19th century in England. Today, it is the second most popular sport in the world behind soccer, with an estimated 220 million people who enjoy playing. For the last three decades, badminton has been a competitive Olympic sport, and with “bird” speeds topping 300 mph in “smash” shots, it certainly makes for exciting spectator sport. Shuttlecocks, also known as birdies or birds, are ...

Vaccine boosts innate immunity in people with dormant immune cells

2024-01-09

Humans are protected by two branches of the immune system. Innate immunity provides built-in defense against widespread characteristics of bacteria and viruses, while adaptive immunity memorizes individual pathogens that a person has already encountered. Vaccines teach the adaptive immune system about new pathogens without having to go through an actual infection. This has greatly contributed to human health, but requires a specific vaccine for each major pathogen. Some vaccines not only teach the adaptive immune system ...

New research shows mobile methadone units are most impactful in rural areas

2024-01-09

While mobile methadone units make a difference in expanding methadone use for patients with opioid addictions, they are likely to be most impactful in rural areas, according to new research. The research was published today in Health Services Research and focused on the impact of adding new treatment services exclusively to rural Louisiana, where like in many other remote parts of the country, there are limited healthcare infrastructures and barriers to transportation. They compared this data to the impact of ...

PNNL kicks off multi-year energy storage, scientific discovery collaboration with Microsoft

2024-01-09

The urgent need to meet global clean energy goals has world leaders searching for faster solutions. To meet that call, the Department of Energy’s Pacific Northwest National Laboratory has teamed with Microsoft to use high-performance computing in the cloud and advanced artificial intelligence to accelerate scientific discovery on a scale not previously demonstrated. The initial focus of the partnership is chemistry and materials science—two scientific fields that underpin solutions to global energy challenges. “The intersection of AI, cloud and high-performance computing, along with human scientists, we believe is key to accelerating the path to meaningful scientific ...

The hidden identity of leukemia

2024-01-09

Researchers from Tokyo Medical and Dental University (TMDU) use various technologies to better characterize a rare form of leukemia on the molecular level Tokyo, Japan – Leukemia is a common term used to refer to a form of blood cancer. However, there are different types of leukemia depending on the cell type involved. One unique form is myeloid/natural killer (NK) cell precursor acute leukemia (MNKPL). Because of its rarity, there is no consensus on the specific characteristics needed to clinically identify this disease. In a recent article ...

Unique framework of tin bimetal organic compound facilitates stable lithium-ion storage

2024-01-09

Battery capacity is one of the primary bottlenecks in efficient renewable energy storage and significant reductions in carbon emissions. As a battery anode that releases electrons in a lithium-ion battery (LIB), tin (Sn) and Sn-mixture alloys could theoretically store more energy at a higher density than more common carbon-based anodes. Pairing a Sn-Ti bimetal element with inexpensive ethylene glycol (Sn-Ti-EG) mitigated many of the challenges of using Sn as an anode material and produced an inexpensive LIB with excellent storage and performance characteristics. Sn and Sn alloys, or mixture of another metal with Sn, could outperform other anode materials ...

Attribution of the extreme drought in eastern China in 2022 and its future risk

2024-01-09

Eastern China was hit by an extreme drought in summer 2022 that caused severe economic and agricultural damage. The event has attracted a great deal of attention not only because of its severe intensity and huge social impacts, but also because it is yet another example within the hot topic of the influence of anthropogenic forcing induced warming on drought extremes and how they might change under different scenarios of continued warming in the future. Recently, Atmospheric and Oceanic Science Letters published ...

Increasing levels of "hype" language in grant applications and publications

2024-01-09

Tsukuba, Japan—The success of scientific endeavors often depends on support from public research grants. Successful applicants increasingly describe their proposed research using promotional language ("hype"); however, it remains unclear whether they use hype in their subsequent research publications. A research team led by the University of Tsukuba analyzed all published research abstracts of projects funded by the US National Institute of Health (NIH) from 1985 to 2020. The analysis covered 139 hype adjectives emphasizing significance ...

Is spa water a fossil of water? Uncover the real ultra-deep water cycles

2024-01-09

Tsukuba, Japan—Although most natural spa waters primarily originate from atmospheric precipitation, such as rain and snow (known as meteoric water), the present study explored the unique qualities of certain spa waters. By analyzing the stable isotope compositions of hydrogen and oxygen in water molecules, researchers have identified distinct characteristics that indicate the presence of long-trapped lithospheric water. They traced the isotopic evolution of this water through sophisticated numerical modeling, and found that various types of water, including those found deep beneath the ...

Light measurement enables estimation of the chemical attributes of spice extracts

2024-01-09

Tsukuba, Japan—Spices and other plant-derived products contain many active components, such as polyphenols and flavonoids. However, even the slightest variations in conditions can considerably affect the extraction efficiency of these active components, posing challenges in determining the exact quantity of active components in the extract solution. In this study, researchers comprehensively measured the fluorescence emitted by polyphenols and flavonoids and analyzed the acquired data using machine learning methods. ...
