Achieving minimal defect density and exceptional homogeneity becomes crucial for enhancing device performance. One commonly employed strategy involves introducing ...

This study, led by Prof. Jiuhui Qu, Dr. Qinghua Ji, and Dr. Wei Zhang from Tsinghua University, focuses on addressing water scarcity by exploring atmospheric water harvesting. The water in the air originates from both natural and forced evaporation, with condensation being the final and crucial step in water harvesting. Condensation involves nucleation, growth, and shedding of water droplets, which are then collected. However, uncontrollable growth of condensed droplets leading to surface flooding is a pressing challenge due to insufficient driving forces, posing a threat to sustainable condensation. To expedite this process and achieve orderly ...

Staying hydrated and consuming appropriate amounts of salt is essential for the survival of terrestrial animals, including humans. The human brain has several regions constituting neural circuits that regulate thirst and salt appetite, in intriguing ways. Previous studies suggested that water or salt ingestion quickly suppresses thirst and salt appetite before the digestive system absorbs the ingested substances, indicating the presence of sensing and feedback mechanisms in digestive organs that help real-time thirst and salt appetite modulation in response to drinking ...

Early in the pandemic, clinicians noticed that certain immunocompromised patients were experiencing persistent SARS-CoV-2 infections, some lasting weeks to months at a time. This raised concerns that one of these cases could be the source of an emerging viral variant that has benefited from an extended battle with the immune system. A prospective study published in the journal Lancet Microbe provides more clarity on which patient populations are at higher risk for prolonged infections —and hints that this fear is likely unwarranted. The ...

A new statistical tool developed by researchers at the University of Chicago improves the ability to find genetic variants that cause disease.

GWAS is a commonly used approach to try to identify genes associated with a range of human traits, including most common diseases. Researchers compare genome sequences ...

As part of the Ice Memory initiative, PSI researchers, with colleagues from the University of Fribourg and Ca’ Foscari University of Venice as well as the Institute of Polar Sciences of the Italian National Research Council (CNR), analysed ice cores drilled in 2018 and 2020 from the Corbassière glacier at Grand Combin in the canton of Valais. A comparison of the two sets of ice cores published in Nature Geoscience shows: Global warming has made at least this glacier unusable as a climate archive. Reliable information about the past climate and air pollution can no longer be obtained from ...

A valuable molecule sourced from the soapbark tree and used as a key ingredient in vaccines, has been replicated in an alternative plant host for the first time, opening unprecedented opportunities for the vaccine industry.  A research collaboration led by the John Innes Centre used the recently published genome sequence of the Chilean soapbark tree (Quillaja saponaria) to track down and map the elusive genes and enzymes in the complicated sequence of steps needed to produce the molecule QS-21.  Using transient expression techniques developed at the John Innes Centre, the team reconstituted the ...

As digital devices progressively replace pen and paper, taking notes by hand is becoming increasingly uncommon in schools and universities. Using a keyboard is recommended because it’s often faster than writing by hand. However, the latter has been found to improve spelling accuracy and memory recall. To find out if the process of forming letters by hand resulted in greater brain connectivity, researchers in Norway now investigated the underlying neural networks involved in both modes of writing. “We ...

Computers can count seals from aerial photographs with lightning speed and reliability. Based on their spatial patterns, the tiny dots on the aerial images can even be assigned to one of the two major species of seals in the Wadden Sea. That is shown in the thesis that marine biologist Jeroen Hoekendijk will defend on January 26 in Wageningen. "To better understand if and how marine mammals like seals are affected by climate change and the disappearance of sea ice, this help from artificial intelligence (AI) in observations is crucial," Hoekendijk said. Hoekendijk carried out his research at the Royal Netherlands Institute ...

These aerosols impact climate directly through scattering and absorbing solar radiation, thus influencing the Earth's radiative balance. The presence of high concentrations of aerosols can lead to the formation of haze and reduce air quality, affecting human health and transportation. Furthermore, the fine particulate matter (PM2.5 and PM10) within aerosols poses health risks ...

“From nature to nature” is the major goal of landscape design. The former is the idea of nature, i.e., landscape architects regard nature as the archetype of design; the latter is the experience of nature, i.e., landscape architects hope people can perceive the natural atmosphere through designed landscape. In this sense, the transformation from idea to experience of nature refers to the process of landscape design, which materializes landscape. According to this, this article focuses on the following topics: 1) what role does nature play as the origin of the landscape design theory; 2) how does nature as an idea promote ...

Fusion energy is being developed as a solution to global energy problems. In particular, the magnetic confinement method, in which ultra-high temperature plasma is confined by a magnetic field, is the most advanced and is considered to be the most promising method for fusion reactors. By this method, the plasma is confined in the reactor in a high-temperature, high-density state by a magnetic field, and the energy released by the fusion reaction in the plasma is converted into electricity. To realize this power generation method, it is essential to predict and control the complex behavior of fusion plasma. One possible control method is digital twin control, in which the fusion plasma ...

'Hidden' stars including a new type of elderly giant nicknamed an 'old smoker' have been spotted for the first time by astronomers. The mystery objects exist at the heart of our Milky Way galaxy and can sit quietly for decades – fading almost to invisibility – before suddenly puffing out clouds of smoke, according to a new study published today in the Monthly Notices of the Royal Astronomical Society. An international team of scientists led by Professor Philip Lucas, of the University of Hertfordshire, made their ground-breaking discovery after monitoring almost a billion stars in infrared light during a 10-year survey ...

Muon spectroscopy is an important experimental technique that scientists use to study the magnetic properties of materials. It is based on “implanting” a spin-polarized muon in the crystal and measuring how its behavior is affected by the surroundings. The technique relies on the idea that the muon will occupy a well-identified site that is mainly determined by electrostatic forces, and that can be found by calculating the material’s electronic structure.  But a new study led by scientists in Italy, Switzerland, UK and Germany has found that, at least for some materials, that is not the end of the story: the muon site ...

SAN ANTONIO, Jan. 25, 2024 — It is a far cry from the traditionally thought-of “vegetative state” in which the mind is absent while the body lives on. Indeed, it is the opposite. Children with “locked-in syndrome,” unable to move or speak, are awake and fully aware of their surroundings. Researchers from The University of Texas Health Science Center at San Antonio (UT Health San Antonio) were the first to report in peer-reviewed medical literature that, after non-fatal drownings, children would be locked in. The team, directed by Peter T. Fox, MD, professor of radiology and neurology and director of UT ...
