Osaka, Japan - Catalysts lie at the heart of a greener and more sustainable future for chemical production. However, many of the catalysts currently in widespread use have limitations that affect their efficiency. Researchers from Osaka University have reported a stable and reusable nickel phosphide nanoalloy catalyst for the hydrogenation of maltose to maltitol that outperforms conventional catalysts. Their findings are published in ACS Sustainable Chemistry & Engineering.
A first-of-its-kind study led by The University of Texas at Austin has found that rock weathering and water storage appear to follow a similar pattern across undulating landscapes where hills rise and fall for miles.
The findings are important because they suggest that these patterns could improve predictions of wildfire and landslide risk and how droughts will affect the landscape, since weathering and water storage influence how water and nutrients flow throughout landscapes.
The fact that the human body is made up of cells is a basic, well-understood concept. Yet amazingly, scientists are still trying to determine the various types of cells that make up our organs and contribute to our health.
A relatively recent technique called single-cell sequencing is enabling researchers to recognize and categorize cell types by characteristics such as which genes they express. But this type of research generates enormous amounts of data, with datasets of hundreds of thousands to millions of cells.
One of the marks of a successful idea in science is how quickly it can develop and evolve. In the case of the Anthropocene, the conceptual evolution has taken place with extraordinary speed. The strikingly influential hypothesis launched by the late Nobel laureate Paul Crutzen (Obituary, 24th Feb 2021) in 2000, was that the actions of an industrialised humanity has impacted the Earth so greatly as to trigger a new geological epoch.
April 19, 2021 -- Ensuring COVID-19 vaccine access for refugee and displaced populations, and addressing health inequities, is vital for an effective pandemic response. Yet, vaccine allocation and distribution has been neither equitable nor inclusive, despite that global leaders have stressed this as a critical aspect to globally overcoming the pandemic, according to a paper published by Columbia University Mailman School of Public Health. Read "Leave No-one Behind: Ensuring Access to COVID-19 vaccines for Refugee and Displaced Populations" in the journal Nature Medicine.
Tools that allow neuroscientists to record and quantify functional activity within the living brain are in great demand. Traditionally, researchers have used techniques such as functional magnetic resonance imaging, but this method cannot record neural activity with high spatial resolution or in moving subjects. In recent years, a technology called optogenetics has shown considerable success in recording neural activity from animals in real time with single neuron resolution.

LOS ALAMOS, N.M., April 19, 2021 -- A recent series of experiments at the National High Magnetic Field Laboratory (National MagLab) at Los Alamos National Laboratory leveraged some of the nation's highest-powered nondestructive magnets to reveal an exotic new phase of matter at high magnetic fields. The experiments studied the unusual Kondo insulator ytterbium dodecaboride (or YbB12) and were the first results from the new 75-tesla duplex magnet housed at the National MagLab's Pulsed Field Facility at Los Alamos.
CORVALLIS, Ore. - Four decades after their capture more than a half-mile below the ocean's surface, three snailfish species have received their scientific names, two of them from school children on Guam in the island's native Chamorro language.
The rare specimens of liparids were collected in the early 1980s in traps set in the Mariana Archipelago in the western Pacific Ocean, deposited with NOAA's Pacific Islands Fisheries Science Center in Hawaii and did not get examined until recently, when they were noticed during the center's move to a new location.
Hand, Foot & Mouth Disease (HFMD) is a generally mild, contagious viral infection common in young children. In Singapore, HFMD is endemic and is most commonly caused by intestinal viruses known as coxsackieviruses and enteroviruses.
Our guts may not provide long-lasting systemic immunity from COVID-19, which is where immune cells circulate through the body to provide protection to other organs, finds a new study published in Frontiers in Immunology.
Philadelphia, April 20, 2021 - American artisan cheese has become increasingly popular over the past few decades. Understanding spoilage concerns and the financial consequences of defects can improve quality, profitability, and sustainability in the American artisan cheesemaking industry.
Flushing a toilet can generate large quantities of microbe-containing aerosols depending on the design, water pressure or flushing power of the toilet. A variety of pathogens are usually found in stagnant water as well as in urine, feces and vomit. When dispersed widely through aerosolization, these pathogens can cause Ebola, norovirus that results in violent food poisoning, as well as COVID-19 caused by SARS-CoV-2.
Embargoed press materials are now available for the virtual Experimental Biology (EB) 2021 meeting, featuring cutting-edge multidisciplinary research from across the life sciences. EB 2021, to be held April 27-30, is the annual meeting of five scientific societies bringing together thousands of scientists and 25 guest societies in one interdisciplinary community.
A biomimicking "spiking" neural network on a microchip has enabled KAUST researchers to lay the foundation for developing more efficient hardware-based artificial intelligence computing systems.
