Nanoparticles are tiny structures up to 100 nanometers in size. They are characterized by different physical and chemical properties and biological activity than their larger material counterparts. - When the starting material on a micro-scale with a specific surface area is broken down to nano size, i.e. into smaller particles, its surface area will increase many times. And it is the ratio of surface to volume that results in the unique properties of nanoparticles, explains Prof. Mahendra Rai from Sant Gadge Baba Amravati University in India. Nanoparticles can be mainly ...

Close relatives of people with metabolic-associated fatty liver disease have a higher risk of developing liver cancer and dying from liver-related diseases, according to a national study from Karolinska Institutet in Sweden published in The Journal of Hepatology. This means that family members could also benefit from the lifestyle advice that is currently only given to patients, the researchers conclude. People with metabolic-associated fatty liver disease (MASLD, formerly known as NAFLD – see fact box) have an elevated risk of developing and dying from liver cancer. MASLD is now the main reason why the number of people developing liver cancer ...

A new study has found that air pollution is preventing pollinators finding flowers because it degrades the scent. A research team comprising the UK Centre for Ecology & Hydrology (UKCEH) and the Universities of Birmingham, Reading, Surrey and Southern Queensland, found that ozone substantially changes the size and scent of floral odour plumes given off by flowers, and that it reduced honeybees' ability to recognise odours by up to 90% from just a few metres away. Ground-level ozone typically forms when nitrogen oxide emissions from vehicles and industrial processes react with volatile organic compounds emitted from vegetation ...

LAWRENCE — Many of us know all too well the addictive nature of many foods marketed in the United States — most call it “junk food.” In fact, this kind of salty, sweet and high-fat fare makes up the lion’s share of what’s marketed to Americans. Researchers employ a more scholarly term for food items featuring purposely tempting combinations of salts, fats and sugars: They’re “hyperpalatable.” Now, an investigator at the University of Kansas has conducted research showing food brands owned by tobacco ...

Computer scientists and mathematicians working in complex systems at the University of Sydney and the Max Planck Institute for Mathematics in the Sciences in Germany have developed new methods to describe what many of us take for granted – how easy, or hard, it can be to fall in and out of sync. Synchronised phenomena are all around us, whether it is human clapping and dancing, or the way fireflies flash, or how our neurons and heart cells interact. However, it is something not fully understood in engineering and science. Associate Professor Joseph Lizier, expert in complex systems at the University of Sydney, said: “We know ...

Developing new drugs is paramount in discovering innovative treatments and preventing diseases. This is vital not only for advancing medicine but also for the overall health and well-being of humanity. Yet, even when drugs demonstrate safety and efficacy in cell and animal models, they frequently encounter hurdles in clinical trials on human.   A single setback for a drug during clinical trials, which involves diverse population groups, can result in significant economic losses. To address this, it is imperative to understand why certain drugs, despite passing the preclinical stages, falter during clinical ...

In the summer of 1931, an unprecedented calamity unfolded along the Yangtze River basin in eastern China - the 1931 Yangtze River flood, known as one of history's deadliest natural disasters. This cataclysmic event submerged a staggering 180,000 km2, affected 25 million lives, and tragically claimed over 2 million lives. Despite its immense societal impact, the origins of this monumental flood have remained largely unexplored, a challenge compounded by the scarcity of historical records and pre-1950s meteorological data in China. Recent access to crucial historical datasets has, however, unlocked the ability to investigate the 1931 Yangtze River flood. A recent study published ...

As a result of the climate crisis, future forests may become unrecognizable. Trees that currently make up European woods may no longer be seen — or they may have moved several hundred meters uphill. Scientists writing in Frontiers in Forests and Global Change have mapped the forests of five vulnerable mountain areas in Italy and modelled the future of these fragile ecosystems. “If I imagine my daughter walking with me as an old man, in our mountain forests, I can imagine that we can see the initial stage of a profound ...

Children have loved Disney princesses since Snow White and the Seven Dwarfs premiered in theaters in 1937. While this adoration continues to grow in terms of princess movie ratings, some parents may wonder what effects these idealized images of young women might have on how their children feel about and express themselves.  According to new research from the University of California, Davis, a favorite princess improved — but did not harm — young children’s ...

The observatory has been used to document the transport of Saharan dust particles across the Atlantic Ocean to the Caribbean, creating the longest-running dust data set in existence. Scientists from many different disciplines use the data to understand how dust particles impact everything from coral reef health to cloud formation and tropical storms. Through a grant from the National Science Foundation (NSF), the University of Miami Rosenstiel School of Marine, Atmospheric, and Earth Science recently completed a major upgrade to its Barbados Atmospheric Chemistry Observatory (BACO), expanding its capability ...

The climate-driven advance of beavers into the Arctic tundra is causing the release of more methane — a greenhouse gas — into the atmosphere. Beavers, as everyone knows, like to make dams. Those dams cause flooding, which inundates vegetation and turns Arctic streams and creeks into a series of ponds. Those beaver ponds and surrounding inundated vegetation can be devoid of oxygen and rich with organic sediment, which releases methane as the material decays. Methane is also released when organics-rich permafrost thaws as the result of heat carried by the spreading water. A study linking Arctic beavers to an increase in the release of methane was ...

Australia’s employment laws and regulations must be updated to reflect the changing nature of work, with many people continuing to work from home long after the COVID-19 pandemic. That’s according to University of South Australia Associate Professor of Organisational Behaviour Dr Ruchi Sinha who says labour laws and protections should be updated to clarify issues related to work hours, overtime, and breaks in a remote work context, now that almost half of all employees are working from home at least once a week. The Australian Institute of Health and Welfare ...

An emerging system which combines rapid imaging with artificial intelligence could help scientists build a comprehensive picture of present and historic environmental change – by swiftly and accurately analysing pollen. Pollen grains from different plant species are unique and identifiable based on their shape. Analysing which pollen grains are captured in samples such as sediment cores from lakes helps scientists understand which plants were thriving at any given point in history, potentially dating back thousands to millions of years. Up to now, scientists have manually ...

Women who live farther from a medical clinic and those who identify as multiracial are more likely to use telemedicine to get abortion pills than to visit a clinic, according to a new study by researchers at the University of Washington School of Medicine. The findings were published Sept. 1 in JAMA Network Open. “One of the main takeaways,” said lead author Anna Fiastro, a family medicine research scientist at UW Medicine, “is that the further patients are from a brick-and-mortar clinic, the more ...

CHAMPAIGN, Ill. — Researchers investigated the relationship between historical traumatic events experienced by Alaska Native communities and epigenetic markers on genes that previous studies have linked to trauma. The new study found a similar pattern among Alaska Native participants, with specific epigenetic differences observed in those who reported experiencing the most intense symptoms of distress when reflecting on historic losses. The study also found that individuals who strongly identified with their Alaska Native heritage and participated in cultural activities generally reported better well-being. The new findings are detailed in the International ...

Milan, Italy: Women exposed to air pollution give birth to smaller babies, according to research that will be presented at the European Respiratory Society International Congress in Milan, Italy [1]. The research also shows that women living in greener areas give birth to bigger babies and this may help counteract the effects of pollution.   There is a strong relationship between birthweight and lung health, with low birthweight children facing a higher risk of asthma and higher rates of chronic obstructive ...

Asian Americans are among the fastest growing populations in the U.S. but are significantly underrepresented in Alzheimer’s disease and related dementias (ADRD) research. This means there is a significant knowledge gap of ADRD in this particular group at a time when the global Asian population is rapidly aging and the burden of ADRD will likely mirror this growth. Thanks to a new award, the Keck School of Medicine of USC’s Mark and Mary Stevens Neuroimaging and Informatics Institute (Stevens INI) is perfectly poised to help bridge the gap.  Professor of ...

New Haven, Conn. — Music can take on many forms in cultures across the globe, but Yale researchers have found in a new study that some themes are universally recognizable by people everywhere with one notable exception — love songs. “All around the world, people sing in similar ways,” said senior author Samuel Mehr, who splits his time between the Yale Child Study Center, where he is an assistant professor adjunct, and the University of Auckland, where he is senior lecturer in psychology. “Music is deeply rooted in human social interaction.” For ...
