It's often said that people who click right away share "chemistry."
An oral antiviral drug that targets a key part of the respiratory syncytial virus (RSV) polymerase and inhibits the synthesis of viral genetic material has been identified, a finding that could provide an effective treatment against RSV disease.
Researchers describe how the microbiomes of people and the homes they live in interact and change each other.
While lower vertebrates can repair their adult hearts after a heart attack, mammals -- including humans -- cannot. The ability to regenerate dead muscle tissue in mammalian hearts disappears just a few days after birth because the heart muscle cells, called cardiomyocytes, exit the cell cycle. In 2020, researchers reported that surgery to remove the left ventricle apex of the heart of pigs, one...
For decades, field-effect transistors enabled by silicon-based semiconductors have powered the electronics revolution. But in recent years, manufacturers have come up against hard physical limits to further size reductions and efficiency gains of silicon chips. That has scientists and engineers looking for alternatives to conventional metal-oxide semiconductor (CMOS) transistors.
A research group has explored the potential production of micro-scale organic electronics for use in bioelectronics via multiphoton 3-D printers.
Over the last two decades, microscopy has seen unprecedented advances in speed and resolution. However, cellular structures are essentially three-dimensional, and conventional super-resolution techniques often lack the necessary resolution in all three directions to capture details at a nanometer scale. A research team has now investigated a super-resolution imaging technique that involves...
Along with high blood pressure, diabetes, and smoking, environmental factors such as air pollution are highly predictive of people's chances of dying, especially from heart attack and stroke, a new study shows.
In the largest epidemiologic study of arsenic and birth outcomes to date, researchers estimated arsenic levels in U.S. private well water sources by county and compared estimates to documented birth outcomes. They found an association between estimated groundwater arsenic concentration and risk of low birth weight.
Most research on immunity to the SARS-CoV-2 virus and COVID-19 vaccine development has focused on antibody responses to the spike protein and other viral surface proteins. But antibodies that recognize the virus's internal proteins could also be important for immunity and disease outcomes, according to a new study.
We need synthetic fertilisers to produce enough food for the world’s population – there are no other alternatives yetSign up for the Rural Network email newsletterJoin the Rural Network group on Facebook to be part of the communityIf water is the source of life, fertiliser is the source of scaleable food production.The increasing cost of fertiliser is one of the largest contributors to a...
In the largest epidemiologic study of arsenic and birth outcomes to date, researchers from the University of Illinois Chicago and collaborating institutions estimated arsenic levels in U.S. private well water sources by county and compared estimates to documented birth outcomes. They found an association between estimated groundwater arsenic concentration and risk of low birth weight.
Within and upon every human being reside countless microorganisms—the microbiota that help shape and direct the lives of their hosts. A similar phenomenon occurs between people, microbes and the homes they share.
The reptile's 2,000-year-old remains are discovered by archaeologists buried in volcanic ash and rock.
Five years ago, researchers from across Europe converged on a cold, fast-moving river in the highlands of Albania for a week of intensive fieldwork. Their mission: to kick off a multiyear effort to assemble a detailed ecological portrait of the Vyosa River, one of Eastern Europe’s last free-flowing waterways. They hoped to draw public attention to the river’s rich wildlife and...
Tests have "ruled out" foot and mouth disease, a government spokesman said.
During the past 10,000 years—the Holocene—human societies became larger and ever more complex. An international team of scientists led by Peter Turchin from the Complexity Science Hub Vienna (CSH) set out to test various theories on what drove this process. According to its analyses of data from Seshat: Global History Databank, the best explanation for the evolution of socio-cultural...

Mass shootings are a source of shared anguish and outrage among Americans and are becoming more frequent. Extreme risk protection orders (ERPOs), also known as gun violence restraining orders or "red flag" laws, are designed to help prevent these shootings. Below, UC Davis Violence Prevention Research Program (VPRP) experts explain what is currently known about mass shootings, how ERPOs work and...
As a result of the worst shock to education and learning in recorded history, learning poverty has increased by a third in low- and middle-income countries, with an estimated 70% of 10-year-olds unable to understand a simple written text, according to a new report published today by the World Bank, UNESCO, UNICEF, UK government Foreign Commonwealth and Development Office (FCDO), USAID, and the...
A recent study out of the Complexity Science Hub Vienna (CSH) found that companies with female board members tend to perform better. The analysis examined the relationship between female board appointments and corporations' financial performance, based on data from about 4.000 Japanese firms collected between 2004 and 2013.
Anthropogenic eutrophication of lake ecosystems is a global problem, especially for some large shallow lakes. But scientists have been unclear why shallow lakes appear prone to eutrophication.
Theoretical scientists have used topological mathematics and machine learning to identify a hidden relationship between nano-scale structures and thermal conductivity in amorphous silicon, a glassy form of the material with no repeating crystalline order.
Campaigners call to prioritise grain for human consumption over its use as a fuelThe US will press ahead with biofuels production, the deputy secretary for agriculture has said, despite increasing concerns over a global food crisis, and calls from campaigners to prioritise grain for human consumption over its use as a fuel.Jewel Bronaugh, the deputy secretary of agriculture, said US farmers could...
