Knee osteoarthritis (OA) is a common cause of pain and joint stiffness. And while physical activity is known to ease symptoms, only one in 10 people regularly exercise.
Emissions of nitrous-oxide (N2O) -- a potent greenhouse gas -- have continued to rise unabated over the past four decades, according to an international team of scientists.
Drugs with the potential to change the course of Alzheimer's disease are expected to be approved by mid-year in the UK. Healthcare services may need to change to ensure that all patients have equitable access to these new modifying anti-amyloid therapies, according to new
Over 17 million insects migrate each year through a single mountain pass on the border between France and Spain, new research shows.
Ten books we loved this year. The post Introducing the Nautilus Summer Reading List appeared first on Nautilus .
Emissions of nitrous oxide—a greenhouse gas more potent than carbon dioxide or methane—continued unabated between 1980 and 2020, a year when more than 10-million metric tons were released into the atmosphere primarily through farming practices, according to a new report by the
Clouds of gas in a distant galaxy are being pushed faster and faster—at more than 10,000 miles per second—out among neighboring stars by blasts of radiation from the supermassive black hole at the galaxy's center. It's a discovery that helps illuminate the way active black
Essential oils, also known as ethereal oils, are volatile, aromatic compounds derived from plants. Found in only about 10% of the plant kingdom, these oils are present in secretory structures such as glands, ducts, cavities, and hairs. Chemically, they belong to categories such
By combining forefront X-ray observations with state-of-the-art supercomputer simulations of the buildup of galaxies over cosmic history, researchers have provided the best modeling to date of the growth of the supermassive black holes found in the centers of galaxies.
An artificial intelligence-powered virtual teammate with a female voice boosts participation and productivity among women on teams dominated by men, according to new research.
Inspired by the material that makes up oyster and abalone shells, engineers have created a new cement composite that is 17 times more crack-resistant than standard cement and 19 times more able to stretch and deform without breaking. The findings could eventually help increase
Researchers have demonstrated miniature soft hydraulic actuators that can be used to control the deformation and motion of soft robots that are less than a millimeter thick. The researchers have also demonstrated that this technique works with shape memory materials, allowing
Researchers have examined viewer responses to images of distressing and neutrally decorated masks and whether personal life history, particularly past experiences of trauma and difficulty, affected how the person perceived the imagery.
Using tools of modern genetics, plant biochemists have produced a new high-yielding oilseed crop variety -- a yellow-seeded variety of Camelina sativa, a close relative of canola, that accumulates 21.4% more oil than ordinary camelina.
Following decades of decline, even fewer birds will darken North American skies by the end of the century, according to a new analysis. The study examines the long-term effects of climate change on the abundance and diversity of bird groups across the continent as a whole while
As space travel becomes more frequent, a new biomarker tool was developed by an international team of researchers to help improve the growing field of aerospace medicine and the health of astronauts.
Haiku poems have reflected humans' experiences in nature for hundreds of years, including observations of bugs and other wildlife. Recently, researchers analyzed which insects were mentioned the most in haiku -- with butterflies, fireflies and singing insects such as crickets
Virtual reality technology can do more than teach weaponry skills in law enforcement and military personnel, a new study suggests: It can accurately record shooting performance and reliably track individuals' progress over time.
Sepsis -- the leading cause of mortality in children around the world -- can present with a wide range of signs and symptoms, making a one-size-fits-all treatment strategy ineffective. Pursuing a precision medicine approach for pediatric sepsis, researchers used artificial
Scientists are peering into the past and uncovering new clues about the early universe. Since light takes a long time to travel through space, they are now able to see how galaxies looked billions of years ago. The astronomers have discovered that spiral galaxies were more
A team of scientists at the Centro Nacional de Investigaciones Cardiovasculares (CNIC) led by Rui Benedito has generated a novel genetic tool, called iSuRe-HadCre, that enables the induction of precise genetic alterations in whole tissues or in individual cells with high
Following decades of decline, even fewer birds will darken North American skies by the end of the century, according to a new analysis by scientists at the University of Illinois Urbana-Champaign. Their study is the first to examine the long-term effects of climate change on
A study featuring more than 3,500 Compulsory Secondary Education (ESO) students and 294 teachers reveals that teachers' commitment to inclusive education favors their students' socio-emotional skills. The findings are published in the journal Learning and Instruction.
When the COVID-19 pandemic hit, it sent shock waves across global supply chains. But manufacturers and other businesses weren't the only ones hit hard: local and international aid organizations, tasked with providing humanitarian assistance during times of crisis, suddenly had
