It is the "time for action", the monarch says in a video address at the COP26 climate summit.
New results relied on a cleaner technique to manipulate the flow of electricity, giving graphene greater conductivity than metals such as copper and gold, and raising its potential for use in telecommunications systems and quantum computers.
The unfolded protein response plays a key role in how Middle East Respiratory Syndrome damages the lungs. MERS is much less common but much lethal than COVID-19, which is also caused by a coronavirus.
The device you are currently reading this article on was born from the silicon revolution. To build modern electrical circuits, researchers control silicon's current-conducting capabilities via doping, which is a process that introduces either negatively charged electrons or positively charged "holes" where electrons used to be. This allows the flow of electricity to be controlled and for silicon...
Earth's atmosphere has a unique ability to cleanse itself by way of invisible molecules in the air that act as minuscule cleanup crews. The most important molecule in that crew is the hydroxyl radical (OH), nicknamed the "detergent of the atmosphere" because of its dominant role in removing pollutants. When the OH molecule chemically interacts with a variety of harmful gases, including the potent...
As 3D printing continues to grow and evolve, diagnostics capable of monitoring builds in real-time have become essential tools for producing quality parts, particularly in emerging printing technologies such as Liquid Metal Jetting (LMJ).

Indian Prime Minister Narendra Modi said the world's third-biggest emitter will zero out pollution by 2070, the boldest statement of intent at the opening of the COP26 climate summit in Glasgow, Scotland.
Centrioles are cylindrical structures involved in the generation of microtubules—fibers inside of cells that form a network to provide structure and shape to cells and to mediate transport processes. In addition, centriole are required to build cilia, hair-like extensions on the cell surface that allow cells to receive and respond to signals from the outside.
Integrated quantum photonics (IQP) is a promising platform for realizing scalable and practical quantum information processing. Up to now, most of the demonstrations with IQP focus on improving the stability, quality, and complexity of experiments for traditional platforms based on bulk and fiber optical elements. A more demanding question is: "Are there experiments possible with IQP that are...
Unpredictable rain is just one of the many challenges soybean producers face every year. However, certain soybean varieties may be better at tolerating an extended period of dry weather than others. Researchers with the University of Tennessee Institute of Agriculture recently published a journal article highlighting which soybeans are better to plant in water-limited areas.
For the first time, sector allocations of the global carbon budget have been provided for both hard-to-abate and all other sectors—12 main macro industry sectors in total, reporting scope 1, 2 and 3 breakdowns.
The theory has been touted as a possible explanation for America's longstanding gender wage gap. But new research suggests women exhibit their competitiveness differently.
It is estimated that about 5-10 volcanoes worldwide are capable of producing a super-eruption that could catastrophically affect global climate. One of these volcanoes hides below the waters of Lake Toba in Sumatra and has caused two super-eruptions in the last one million years. But when will the next one be? Will there be any warning signs? To answer these questions, an international team of...
As researchers investigate reasons for America's persistent gender wage gap, one possible explanation that has emerged in roughly the last decade is that women may be less competitive than men, and are therefore passed over for higher-ranking roles with larger salaries.
An international team of researchers has identified genes associated with plant survival in one of the harshest environments on Earth: the Atacama Desert in Chile. Their findings, published in Proceedings of the National Academy of Sciences (PNAS), may help scientists breed resilient crops that can thrive in increasingly drier climates.
A team of physicists has discovered how DNA molecules self-organize into adhesive patches between particles in response to assembly instructions. Its findings offer a "proof of concept" for an innovative way to produce materials with a well-defined connectivity between the particles.
Women are less likely than men to ask for more time to complete projects with adjustable deadlines at work or school, new research finds.
A study using the thermal history and biosignatures of the upper few kilometers of some of the oldest rocks on Earth place constraints on the evolutionary history of microbes in the deep biosphere. A new study, published in PNAS, Proceedings of the National Academy of Sciences, show that the rocks were uninhabitable for much of their lifetimes with the longest period of habitability not extending...
It is estimated that about 5 to 10 volcanoes worldwide are capable of producing a super-eruption that could catastrophically affect global climate. One of these volcanoes hides below the waters of Lake Toba in Sumatra and has caused two super-eruptions in the last million years. But when will the next one be? Will there be any warning signs?
Curbing climate change and improving air quality could provide greater health benefits in our lifetime than previously thought, potentially preventing millions of deaths and hospitalizations in the U.S. alone during the next half-century, new research...
The mid-ocean "twilight zone" holds the key to several tantalizing questions about the marine food web and carbon-sequestering capacity of the ocean. But studying this vast and remote area is extremely difficult. Many inhabitants of the twilight zone are easily destroyed during sampling—or are quick to avoid any disturbance—so it's difficult to sample them with traditional nets. Advances in...
A temperature increase of around 1.5°C—just under the maximum target agreed at the COP23 Paris meeting in 2017—can have a marked impact on algae and animal species living on UK coastlines, new research has found.
In the last few years, a class of materials called antiferroelectrics has been increasingly studied for its potential applications in modern computer memory devices. Research has shown that antiferroelectric-based memories might have greater energy efficiency and faster read and write speeds than conventional memories, among other appealing attributes. Further, the same compounds that can exhibit...
Throughout the COVID-19 pandemic, conspiracy theorists have exploited the conditional nature of science and questioned the trustworthiness and motives of federal agencies and officials to depict scientists and health authorities as malign actors.
If by 2052 a computer could match the human brain then we need better ways to build it“Progress in AI is something that will take a while to happen, but [that] doesn’t make it science fiction.” So Stuart Russell, the University of California computing professor, told the Guardian at the weekend. The scientist said researchers had been “spooked” by their own success in the field. Prof...
A team of researchers has discovered unexpectedly familiar behavior in the antiferroelectric material known as zirconium dioxide, or zirconia.
Researchers show it is possible to improve specific human brain functions related to self-control and mental flexibility by merging artificial intelligence with targeted electrical brain stimulation.
As COP26 leaders gather in the UK, new research shows a temperature increase of around 1.5°C -- just under the maximum target agreed at the COP23 Paris meeting in 2017 -- can have a marked impact on algae and animal species living on our coastlines.
