Red deer may become less sociable as they grow old to reduce the risk of picking up diseases, while older house sparrows seem to have fewer social interactions as their peers die off, according to new research which shows humans are not the only animals to change our social behaviour as we age.  A collection of 16 studies, including six from the University of Leeds, have been published today as part of a special issue of the Philosophical Transactions of the Royal Society, investigating ageing and society across the natural world.    One study into red deer shows that ...

Diabetes is an increasingly pervasive disease, currently affecting over 500 million adults worldwide. Since there is as yet no cure for type 1 or type 2 diabetes, patients must regularly monitor their BGLs to keep them in check. Though BGL-measuring devices relying on painful finger pricks have been the gold standard for decades, modern technology is slowly opening doors to better alternatives. Many researchers have proposed noninvasive methods to monitor BGLs using widely available wearable devices, such as smartwatches. For example, by placing the LEDs ...

Opioid use disorder (OUD) is a growing public health problem among pregnant and parenting people in the U.S. Between 1999 and 2014, the number of pregnant women with OUD increased by more than four times. This trend also coincides with a rise in pregnancy-associated maternal overdose mortality. Researchers at Thomas Jefferson University, led by Meghan Gannon, PhD, MSPH, investigated how community-based supports, like doulas, can be integrated into health care for mothers who use opioids. Using a social network analysis, ...

Lead exposure is a risk to any human, but children are most vulnerable to the element’s neurotoxicity, which can lead to developmental delays, learning difficulties and mood changes among other symptoms. There has been some progress in reducing exposure and preventing neurotoxicity, but hundreds of thousands of American children are still affected. A new study by Thomas Jefferson University neuroscientist Jay Schneider, PhD, suggests that the toxic effects of lead can be mitigated by attentive maternal care and an enriched environment ...

To Alex Hughes, Assistant Professor in Bioengineering within Penn Engineering and in Cell and Developmental Biology within Penn Medicine, the kidney is a work of art. “I find the development of the kidney to be a really beautiful process,” says Hughes. Most people only ever see the organ in cross-section, through textbooks or by dissecting animal kidneys in high school biology class: a bean-shaped slice with lots of tiny tubes. “I think that really undersells how amazing the structure is,” says ...

Since its founding in 2008, the short-term homestay platform Airbnb has expanded to 100,000 cities in more than 220 countries, and, according to data from the company, 1.5 billion guests had stayed in Airbnb-listed properties through 2023. Much of the academic research on Airbnb activity comes from economics and business literature and focuses on housing-supply impacts, says David Kirk, professor of criminology at the University of Pennsylvania. Yet research on neighborhood impacts is limited, and that research neglects the impacts of Airbnb activity on measures of community cohesion and safety. Kirk teamed with University of Cambridge criminologist ...

Invasive plants are doing more than just taking over landscapes — they’re also changing the soil beneath them. A new study co-authored by Matthew McCary, assistant professor of biosciences at Rice University, reveals that these species are reshaping soil microbial communities across the U.S., making them more uniform and altering how ecosystems function. The findings, published in Proceedings of the National Academy of Sciences on Oct. 24, shed light on the far-reaching impacts of invasive plants, which extend beyond what we see above ground. The ...

Invasive species in Florida like Nile monitors and Argentine black-and-white tegus pose a growing threat to the Sunshine State’s environment, economy and public safety. South Florida’s warm climate, disturbed habitats and bustling pet trade have made it a hotspot for these non-native, cryptic reptiles. However, finding these elusive creatures has always been a challenge – until now. University of Florida researchers are showcasing how a focused outreach initiative in Palm Beach County has led to a successful increase in reports of invasive reptiles in Florida. The findings are documented in the latest study published in Scientific Reports and authored by researchers at UF/IFAS ...

Malaria kills over 600,000 people a year, and as the climate warms, the potential range of the disease is growing. While some drugs can effectively prevent and treat malaria, resistance to those drugs is also on the rise.   New research from University of Utah Health has identified a promising target for new antimalarial drugs: a protein called DMT1, which allows single-celled malaria parasites to use iron, which is critical for parasites to survive and reproduce.   The results suggest that medications that block DMT1 might be very effective against malaria.   The new results are published in PNAS. An ironic mystery Paul Sigala, ...

U.S. immigration law and the legal categorizations it imposes on migrants shape the journeys of migrant children from Central America as they move through Mexico toward the southern U.S. border, according to a new Yale study. In the study, sociologist Ángel Escamilla García documents the various hard decisions Central American youth are forced to make during their journeys to maximize their chances of not being deported once they reach the United States. Those choices include concealing sexual assaults, beatings, and other crimes ...

RICHLAND, Wash.—Scientists are gathering at the Department of Energy’s Pacific Northwest National Laboratory this week for a first-ever conference to consider ways to protect critical systems such as our electrical grid, water treatment plants and financial networks that are vulnerable in new ways.   The Cyber Supply Chain Risk Management Conference, known as CySCRM 2024, is being held on the PNNL campus Tuesday-Wednesday, Oct. 29-30.   It’s a new kind of science meeting, one that scientist Jess Smith and colleagues felt compelled to create as they eye a new kind of risk—a ...

Newly available blood tests to screen for colorectal cancer sound far more appealing than a standard colonoscopy. Instead of clearing your bowels and undergoing an invasive procedure, the tests require only a simple blood draw. But are the tests effective? A study led by researchers at Stanford Medicine concluded that the new tests are ideal for people who shy away from other colorectal cancer screening. However, if too many people who would have undergone colonoscopies or stool-based tests switch to the blood tests, colorectal cancer death rates will rise. Because the more established colonoscopies and stool tests ...

Derek Urwin has a special stake in his work as a cancer control researcher. After undergraduate studies in applied mathematics at UCLA, he became a firefighter. His inspiration to launch a second career as a scientist was the loss of his brother, Isaac, who died of leukemia at only 33 despite no history of cancer in their family. Working with Anastassia Alexandrova, a professor of chemistry and biochemistry in the UCLA College, he earned his doctorate. Urwin is now a UCLA adjunct professor of chemistry — and still a full-time firefighter with the Los Angeles County Fire Department. In a recent publication, his science shed new light on the chemical underpinnings of exposures ...

PHILADELPHIA (October 28, 2024) – The University of Pennsylvania School of Nursing (Penn Nursing) has been awarded a $3.2 million, 5-year grant from the National Institute of Nursing Research (NINR) to scale out an evidence-based secure firearm storage intervention at Children’s Hospital of Philadelphia (CHOP). Firearms are now the leading cause of death for U.S. children and teens, driving the largest spike in children’s mortality in more than 50 years. The study aims to keep children safer from firearm injury and mortality by promoting secure firearm storage. The intervention, ...

Taking inspiration from bird feathers, Princeton engineers have found that adding rows of flaps to a remote-controlled aircraft’s wings improves flight performance and helps prevent stalling, a condition that can jeopardize a plane’s ability to stay aloft.  “These flaps can both help the plane avoid stall and make it easier to regain control when stall does occur,” said Aimy Wissa, assistant professor of mechanical and aerospace engineering and principal investigator of the study, published in the Proceedings ...

Marine phytoplankton are fundamental to Earth’s ecology and biogeochemistry. Our understanding of the large-scale dynamics of phytoplankton biomass has greatly benefited from, and is largely based on, satellite ocean color observations from which chlorophyll-a (Chla), a commonly used proxy for carbon biomass, can be estimated. However, ocean color satellites only measure a small portion of the surface ocean, meaning that subsurface phytoplankton biomass is not directly monitored. Chla is also an imperfect ...

    Images There's a famous piece of advice from hockey, attributed to Wayne Gretzky, about how it's better to skate to where the puck is headed rather than where it is.   Research is now showing that regulations designed to protect Lake Erie's water quality are heeding the Great One's words when it comes to safeguarding the Great Lake's fisheries.   Specifically, the currently recommended limits on the flow of nutrients into Lake Erie from agriculture may be too restrictive for some species of fish. They are, however, suited to maintain healthy fisheries until the ...

201.6 million years ago, one of the Earth's five great mass extinctions took place, when three-quarters of all living species suddenly disappeared. The wipeout coincided with massive volcanic eruptions that split apart Pangaea, a giant continent then comprising almost all the planet's land. Millions of cubic miles of lava erupted over some 600,000 years, separating what are now the Americas, Europe and North Africa. It marked the end of the Triassic period and the beginning of the Jurassic, the period when dinosaurs arose to take the place of Triassic creatures and dominate the planet. The exact mechanisms of the End Triassic Extinction have long been debated, ...

“We found that 30 percent of the regions with available data have fully decoupled carbon emissions from economic growth. Regions with high incomes and a history of carbon-intensive industries, as well as those with significant shares of service and manufacturing sectors were particularly successful in reducing carbon emissions while still experiencing economic growth,“ says Anders Levermann, co-author and head of the research department “Complexity Science” at PIK. “A stabilization of the global mean temperature is only possible with net-zero carbon emissions. That ...

A landmark study led by WEHI and La Trobe University has found a potential new diagnostic marker that could be used to better detect the level of tissue damage in our bodies.  Extracellular vesicles (EVs) are small ‘delivery trucks’ released by our cells that deliver important materials to other cells to aid cellular communication. This study revealed, for the first time, a link between levels of EVs in the blood and tissue damage caused by diseases such as leukaemia. Researchers hope to leverage the ...

Public and community engagement in decision making is key to enhancing urban living conditions and the environment in China, a new study says. There has been significant progress through legislation to promote the role of citizens in environment and nature-based solutions (NBS), but progress in involving the public in projects has been limited, the research shows. However, there has been some work in gathering public opinion and involving them in the project design and decision-making of government-led and large NBS projects. Researchers found smaller local NBS projects tend to see higher levels of public participation, ...
