In the fight against antibiotic resistance, a new technology developed at Chalmers University of Technology, in Sweden, can be of great importance when, for example, hip and knee implants are surgically inserted. By heating up small nanorods of gold with near-infrared light (NIR), the bacteria are killed, and the surface of the implant becomes sterile. The researchers are now presenting a new study that increases the understanding of how the gold rods are affected by light and how the temperature in them can be measured. Infections can occur during surgical procedures, with the risk increasing significantly when foreign materials, ...

Discovery of cancer risk associations for six novel genes Scientists at deCODE genetics/Amgen, and their collaborators have discovered six novel genes with rare germline variants that associate with cancer risk. The findings are published today in Nature Genetics under the title “Gene-based burden tests of rare germline variants identify six cancer susceptibility genes”. A subset of cancers arises in individuals who are born with rare sequence variants that significantly alter their cancer risk. The discovery of such variants, like those in the BRCA1- and BRCA2 genes, has led to improved early cancer detection ...

The unprecedented temperatures in the summer of 2022 caused more than 68,000 deaths on the continent, according to a study by the Barcelona Institute for Global Health (ISGlobal), a centre supported by the 'la Caixa' Foundation. A new study has now found that more than half - 56% - of the heat-related deaths in the summer of 2022 were related to human-induced climate change. According to the research, 38,154 of the 68,593 heat-related deaths in the summer of 2022 would not have occurred without anthropogenic warming. The ...

WASHINGTON (October 29, 2024) – A new study published today details the ways in which the 2020 U.S. election not only incited new hate content in online communities but also how it brought those communities closer together around online hate speech. The research has wider implications for better understanding how the online hate universe multiplies and hardens around local and national events such as elections, and how smaller, less regulated platforms like Telegram play a key role in that universe by creating and sustaining hate content. The study – published in the journal npj Complexity, part of the Nature portfolio of journals – ...

The study aimed to identify clinical subtypes in patients with schizophrenia, the results of which were published in Springer-Nature’s journal Schizophrenia on October 29, 2024. Key Points In patients with schizophrenia, a decline in social cognition—a fundamental skill for interpersonal ...

A pitiful sound from tinny speakers, sad virtual eyes, trembling robot arms: it doesn’t take much to feel sorry for a robot. This is the conclusion of a study by Marieke Wieringa, who will be defending her PhD thesis at Radboud University on 5 November. But she warns that our human compassion could also be exploited: just wait until companies find a revenue model for emotional manipulation by robots. Objectively, we know that a robot cannot experience pain. Still, under certain circumstances, ...

There is power in numbers, or so the saying goes. But in the ocean, scientists are finding that fish that group together don’t necessarily survive together. In some cases, the more fish there are, the larger a target they make for predators.  This is what MIT and Norwegian oceanographers observed recently when they explored a wide swath of ocean off the coast of Norway during the height of spawning season for capelin — a small Arctic fish about the size of an anchovy. Billions of capelin migrate each February from the edge of the Arctic ...

A living cell is a bustling metropolis, with countless molecules and proteins navigating crowded spaces in every direction. Cell division is a grand event which completely transforms the landscape. The cell starts behaving like the host of an international competition, reconfiguring entire streets, relocating buildings and rerouting its transportation systems.  For decades, researchers have been captivated by the cell's ability to organise such a dramatic transformation. Central to the process is the microtubule cytoskeleton, a network of fibres which provides structural support and facilitates movement within the cell, ensuring that chromosomes ...

Using laser-guided imaging to peer through dense jungle forests, Tulane University researchers have uncovered vast unexplored Maya settlements in Mexico and a better understanding of the ancient civilization's extent and complexity. The new research, published in the journal Antiquity, was led by Tulane University anthropology doctoral student Luke Auld-Thomas and his advisor, Professor Marcello A. Canuto. The team used lidar, a laser-based detection system, to survey 50 square miles of land in Campeche, Mexico, an area largely overlooked by archaeologists. Their findings included evidence of more than 6,500 pre-Hispanic structures, including a previously unknown ...

Our ability to see starts with the light-sensitive photoreceptor cells in our eyes. A specific region of the retina, termed fovea, is responsible for sharp vision. Here, the color-sensitive cone photoreceptors allow us to detect even the smallest details. The density of these cells varies from person to person. Additionally, when we fixate on an object, our eyes make subtle, continuous movements, which also differ between individuals. Researchers from the University Hospital Bonn (UKB) and the University of Bonn have now investigated how sharp vision is linked to these tiny eye movements and ...

A genetic signature in newborns can predict neonatal sepsis before symptoms even start to show, according to a new study.   The study, led by UBC and SFU researchers in collaboration with the Medical Research Council (MRC) Unit The Gambia, has the potential to help healthcare workers diagnose babies earlier, including in lower- and middle-income countries (LMICs) where neonatal sepsis is of particular concern. The research, published today in eBiomedicine, is funded by the National Institutes of Health and the Canadian Institutes of Health Research.   “Neonatal sepsis is caused by the body’s irregular response ...

Researchers have developed a machine learning algorithm to accurately detect heart murmurs in dogs, one of the main indicators of cardiac disease, which affects a large proportion of some smaller breeds such as King Charles Spaniels. The research team, led by the University of Cambridge, adapted an algorithm originally designed for humans and found it could automatically detect and grade heart murmurs in dogs, based on audio recordings from digital stethoscopes. In tests, the algorithm detected heart murmurs with a sensitivity ...

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 ...
