In a study led by Prof. Wei Xu (Interdisciplinary Materials Research Center, School of Materials Science and Engineering, Tongji University) and published in the journal National Science Review, a research team achieved the successful synthesis of a one-dimensional carbon chain on the Au(111) surface, with the longest chain containing approximately 120 carbon atoms, and the polyynic nature of the carbon chain was unambiguously characterized by bond-resolved atomic force microscopy (AFM).

Donations for a political candidate can be motivated by support for that candidate or by opposition to the candidate's opponent. New research published in Social Science Quarterly found that female Democrats and non-white male Democrats in the United States have a fundraising advantage when running against a white male Republican. Female Republicans or non-white male Republicans do not have this advantage when running against white male Democrats.

Creating multiple universes to see how they run might be tempting to scientists, but it's obviously not possible. That is, as long as you need physical universes. If you can make do with virtual ones, there are far more options.

Finding ways to capture, store, and use carbon dioxide (CO2) remains an urgent global problem. As temperatures continue to rise, keeping CO2 from entering the atmosphere can help limit warming where carbon-based fuels are still needed.

Focusing attention on your mobile phone instead of your partner doesn't just strain your relationship—it also affects women's creativity in the workplace, caution researchers from the Universities of Bath, Aston, and IESE Business School.

The photoelectrochemical (PEC) overall water-splitting reaction (OWS) has been fully developed in the past decade, especially in new catalysts, characterization methods and reaction mechanisms. Compared with the hydrogen evolution reaction (HER), the oxygen evolution reaction (OER) is deemed the bottleneck of OWS due to its sluggish kinetics.

Clocks losing an hour in spring significantly affects how investors respond to companies that reveal unexpected levels of earnings, research shows.

Carbon monoxide emissions from industrial production have serious consequences for human health and are a strong indicator of overall air pollution levels. Many countries aim to reduce their emissions, but they cannot control air flows originating in other regions. A new study from the University of Illinois Urbana-Champaign looks at global flows of air pollution and how they relate to economic activity in the global supply chain.

High-performance active terahertz (THz) modulators are of great importance for next generation communication technology. However, they currently suffer from the tradeoff between modulation depth and speed.

The demand for microelectromechanical systems (MEMS) resilient to harsh environments is growing. Silicon-based MEMS struggle under extreme conditions, limited by their performance at elevated temperatures. Silicon carbide (SiC) stands out as a promising solution, offering unmatched thermal, electrical, and mechanical advantages for creating enduring MEMS.

Conspiracy theorists get a bad rap in popular culture, yet research has shown that most Americans believe conspiracy theories of some sort. Why then, if most of us believe conspiracies, do we generally think of conspiracy theorists as loony?

A new automated workflow developed by scientists at Lawrence Berkeley National Laboratory (Berkeley Lab) has the potential to allow researchers to analyze the products of their reaction experiments in real time, a key capability needed for future automated chemical processes.

Researchers are developing a technique that uses the special synchrotron X-ray light from the Swiss Light Source SLS to non-destructively digitize recordings from high-value historic audio tapes—including treasures from the Montreux Jazz Festival archive, such as a rare recording of the King of the Blues, B.B. King.

Scientists at the University of Wisconsin–Madison have developed a cost-effective and environmentally sustainable way to make a popular pain reliever and other valuable products from plants instead of petroleum.

Substituting plastics with alternative materials is likely to result in increased GHG emissions, according to research from the University of Sheffield.

The 4.8 magnitude earthquake that shook the Northeast on April 5 didn't seem to cause much damage, but it was enough to send tremors of concern through anyone who felt it. It's not that the region never experiences seismic shifts. It's just that most earthquakes in the region go undetected.

A nanosized polymer, developed by a research team from Ben-Gurion University of the Negev, can selectively deliver chemotherapeutic drugs to blood vessels that feed tumors and metastases and has emerged as an effective treatment for advanced cancer. The polymer eliminates colorectal cancer liver metastases and prolongs mice survival after a single dose therapy.

Since the 1970s, modern antibiotic discovery has been experiencing a lull. Now the World Health Organization has declared the antimicrobial resistance crisis as one of the top 10 global public health threats.

University of Michigan researchers have discovered that a worm commonly used in the study of biology uses a set of proteins unlike those seen in other studied organisms to protect the ends of its DNA.

Over the past four years, many of us have become accustomed to a swab up the nose to test for COVID-19, using at-home rapid antigen tests or the more accurate clinic-provided PCR tests with a longer processing time. Now a new diagnostic tool developed by UC Santa Cruz Distinguished Professor of Electrical and Computer Engineering Holger Schmidt and his collaborators can test for SARS-CoV-2 and Zika virus with the same or better accuracy as high-precision PCR tests in a matter of hours.

Researchers at the University of California San Diego School of Global Policy and Strategy have developed a new method to predict the financial impacts climate change will have on agriculture, which can help support food security and financial stability for countries increasingly prone to climate catastrophes.

Some deeper areas of the Great Barrier Reef are insulated from harmful heat waves—but that protection will be lost if global warming continues, according to new research.

One of the most abundant and deadliest organisms on Earth is a virus called a bacteriophage (phage). These predators have lethal precision against their targets—not humans, but bacteria. Different phages have evolved to target different bacteria and play a critical role in microbial ecology. Recently, ADA Forsyth scientists exploring the complex interactions of microbes in the oral microbiome discovered a third player influencing the phage-bacterial arms race—ultrasmall bacterial parasites, called Saccharibacteria or TM7.

Between March 2020 and September 2021, millions of workers furloughed under the UK government's Coronavirus Job Retention Scheme lived what for many of us is a dream: being paid not to work.

Last week, at the annual Rencontres de Moriond conference, the CMS collaboration presented a measurement of the effective leptonic electroweak mixing angle. The result is the most precise measurement performed at a hadron collider to date and is in good agreement with the prediction from the Standard Model.
