A team of international researchers went back to the formation of the solar system 4.6 billion years ago to gain new insights into the cosmic origin of the heaviest elements on the period-ic table.

Both Democrats and Republicans overwhelmingly favor politicians who support generous COVID-19 relief spending, yet remain deeply polarized over the legitimacy of the 2020 presidential election results and former President Donald Trump's second impeachment. Meanwhile, political experts find that the former president's actions and those taken by congressional supporters in the aftermath of the election represent serious departures from American democratic norms.

In recent years, engineers have found ways to modify the properties of some "two- dimensional" materials, which are just one or a few atoms thick, by stacking two layers together and rotating one slightly in relation to the other. This creates what are known as moiré patterns, where tiny shifts in the alignment of atoms between the two sheets create larger-scale patterns. It also changes the way electrons move through the material, in potentially useful ways.

A vast iceberg almost the size of Greater London has broken away from the Antarctic ice shelf near a British research station, the British Antarctic Survey said Friday.

Whilst a great deal of research has studied the rates of photons escaping from cold atomic gases, these studies have used a scalar description of light leaving some of its properties untested. In a new paper published in EPJ B Louis Bellando, a post-doctoral researcher at LOMA, University of Bordeaux, France, and his coauthors—Aharon Gero and Eric Akkermans, Technion-Israel Institute of Technology, Israel, and Robin Kaiser, Université Côte d'Azur, France—aim to numerically investigative the roles...

Neutron scattering is a technique commonly used in physics and biology to understand the composition of complex multicomponent mixtures and is increasingly being used to study applied materials such as food. A new paper published in EPJ E by Gregory N Smith, Niels Bohr Institute, University of Copenhagen, Denmark, shows an example of neutron scattering in the area of food science. Smith uses neutron scattering to better investigate casein micelles in milk, with the aim of developing an approach for future research.

NUS scientists have devised a new method for the synthesis of nanographene molecules with a high product yield for the development of next generation quantum devices.

Who hasn't looked at the sky on a mild summer night and thought about the vastness of the universe? The trained eye can see the Andromeda galaxy as a distant spot. Thanks to the latest telescopes, we know that it consists of over a trillion stars. In the "nanocosm," clusters of individual light sources, such as molecules, also appear as points.

The Innovation Center of NanoMedicine reported in ACS Nano together with the group of Prof. Yu Matsumoto of Otorhinolaryngology and Head and Neck Surgery and the group of Prof. Horacio Cabral of the Department of Bioengineering in the University of Tokyo that the efficacy of polymeric nano-micelles with different drug activation profile depends on the expression level of c-Myc, one of the major proto-oncogenes, has been developed.

Climate alone is not a driver for human behavior. The choices that people make in the face of changing conditions take place in a larger human context. And studies that combine insights from archeologists and environmental scientists can offer more nuanced lessons about how people have responded—sometimes successfully—to long-term environmental changes.

Economists and urban planners generally agree that local pollution sources disproportionally impact racial minorities in the U.S. The reasons for this are largely unclear, but a University of Illinois study provides new insights into the issue.

Scientists at UCL and the IIT—Istituto Italiano di Tecnologia (Italian Institute of Technology) have created a temporary tattoo with light-emitting technology used in TV and smartphone screens, paving the way for a new type of 'smart tattoo' with a range of potential uses.

A Mason Engineering researcher has discovered that artificial microswimmers accumulate where their speed is minimized, an idea that could have implications for improving the efficacy of targeted cancer therapy.

An injection of pandemic aid filled Americans' wallets last month, though spending rose modestly, according to government data released Friday, giving a boost to the economy as it claws its way back from recession.

A team of researchers from the University of Rhode Island's Graduate School of Oceanography and their collaborators have revealed that the abundant microbes living in ancient sediment below the seafloor are sustained primarily by chemicals created by the natural irradiation of water molecules.

An international team of researchers has used computer simulations to show that it was likely a combination of climate change and human hunting that led to the extinction of the woolly mammoth. They have written a paper describing their findings, available on the bioRxiv preprint server—in it, they suggest that were it not for human hunters, the mammoths would have lasted another 4,000 years.

To stay in step with their times, make their voices heard and play a decisive role in shaping major future directions, researchers must move toward a "sustainability science."

Mixed-gender software development teams perform better than male-only teams, with female developers helping offset psychopathic traits of some male developers, according to researchers at Lero, the Science Foundation Ireland Research Centre for Software.

It seems like every day we learn of a new risk posed to native plants, from bushfires to climate change. But they're not going out without a—er—bang.

A team of researchers from Stanford University, working with associates from the Gladstone Institute of Data Science and Biotechnology and King Abdulaziz University, has developed a software system that can be used for integrative single-cell chromatin accessibility analysis. In their paper published in the journal Nature Genetics, the group describes the software, the platforms on which it can be run, and how it might be used by researchers.

The largest and most destructive earthquakes on the planet happen in places where two tectonic plates collide. In our new research, published today in Nature Communications, we have produced new models of where and how rocks melt in these collision zones in the deep Earth.

A team of researchers from Indonesia and Singapore has found evidence of the continued existence of a bird long thought extinct. In their paper published in the journal BirdingASIA, the team describes the history of the bird, why it was thought to be extinct and how it was found in Borneo.

The COVID-19 virus holds some mysteries. Scientists remain in the dark on aspects of how it fuses and enters the host cell; how it assembles itself; and how it buds off the host cell.

The unprecedented cost of the 2018 Kilauea eruption in Hawai'i reflects the intersection of distinct physical and social phenomena: infrequent, highly destructive eruptions, and atypically high population growth, according to a new study published in Nature Communications and led by University of Hawai'i at Mānoa researchers.

Doppler radar improves lives by peeking inside air masses to predict the weather. A Purdue University team is using similar technology to look inside living cells, introducing a method to detect pathogens and treat infections in ways that scientists never have before.
