UVM scientists find space-for-time substitutions exaggerate urban bird–habitat ecological relationships

A study from University of Vermont researchers suggests that some bird species may be more flexible to habitat changes than previously understood, creating new opportunities for supporting populations through city planting efforts. The team found that space-for-time substitutions, a method for predicting future species counts using hab...

Gut dysbiosis and fecal microbiota transplantation in pancreatic cancer: Current status and perspectives

Research highlights the role of gut dysbiosis in pancreatic ductal adenocarcinoma (PDAC), with specific microbial profiles associated with PDAC. Fecal microbiota transplantation (FMT) is proposed as a potential adjunct therapy to improve patient outcomes through microbiome modulation and immune system recalibration.

Lurie Children’s study to link genetics and long-term cardiorespiratory outcomes of children born prematurely for more precise diagnosis and treatment

A new NIH-funded study at Ann & Robert H Lurie Children's Hospital of Chicago will use AI to identify disease subtypes based on genetic data and associated outcomes in premature infants. The four-year study aims to establish disease subtypes that can predict longer-term cardiorespiratory outcomes, enabling earlier interventions.

GIST scientists unveil strategies to make self-driven vehicles passenger-friendly

Researchers developed a multimodal dataset, TimelyTale, to gather passenger-specific sensor data for context-relevant explanations. The approach effectively identified the timing and frequency of passenger demands for explanations, enabling the creation of a machine-learning model to predict the best time for providing an explanation.

Breakthrough in energy-efficient avalanche-based amorphization could revolutionize data storage

Researchers developed a new method for amorphizing indium selenide wires, requiring as little as one billion times less power density. The process resembles an avalanche and an earthquake, triggering rapid deformation and linking small areas into larger ones, potentially unlocking wider applications for phase-change memory technology.

Five minutes of exercise a day could lower blood pressure

A new study suggests that adding physical activity into daily life can help lower blood pressure. Replacing sedentary behaviors with 20-27 minutes of exercise per day was estimated to lead to a clinically meaningful reduction in blood pressure, while just five minutes of activity a day was also associated with reduced levels.

New analysis uncovers significant decrease in mental health staffing during austerity

The NHS mental health workforce decreased significantly during austerity, with notable disparity in staffing levels across the country. The growth in the mental health workforce appears about half that of the wider clinical workforce, suggesting that ambitions to create a 'parity of esteem' between mental and physical health conditions...

Salmon frequently mislabeled in Seattle grocery stores and sushi restaurants

A recent study by Tracie Delgado and colleagues found that 18% of salmon samples from Seattle grocery stores and sushi restaurants were mislabeled. The researchers called for continued development and enforcement of legislation against salmon fraud to prevent accurate tracking of supply chains and conserve wild salmon.

Brain stars hold our memories

A study published in Nature reveals that astrocytes, star-shaped brain cells, play a crucial role in storing and retrieving memories. Researchers found that these non-neuronal cell types work closely with groups of neurons called engrams to regulate the formation and recall of memories.

Balancing quantity and quality: How X/Twitter's algorithm influences our consumption of news

Researchers found that X/Twitter's algorithm presents users with milder and less polarizing information than chronological timeline news. However, this has implications for the use of these platforms to find trustworthy news, as users question its credibility even when coming from legitimate sources.

Cachexia decoded: Why diagnosis matters in cancer survival

A new study from Japan confirms that definitive criteria for lower cachexia prevalence rates are linked to reduced survival rates in cancer patients. The study found that the diagnostic criteria used for cachexia detection can affect reported prevalence and survival outcomes, emphasizing the need for accurate diagnosis.

What happens in your brain while you watch a movie

Researchers used fMRI scans to study how the brain responds to complex audio and visual stimuli while watching movies. They identified 24 distinct brain networks associated with specific aspects of sensory or cognitive processing, such as recognizing human faces or bodies, movement, and social interactions.

Nasal swab tests predict COVID-19 disease severity, Emory study finds

Researchers developed a new diagnostic tool called FlowBEAT to measure antibodies in nasal cavities, finding that more than 70% of people with mild or moderate COVID-19 develop protective autoantibodies in the nose. These autoantibodies may play a role in regulating the immune system and preventing excessive inflammation.

Very early medication abortion is effective and safe

A large international study found that very early medication abortion is equally effective and safe as waiting for intrauterine pregnancy confirmation. The study included over 1,500 women who received two drugs – mifepristone and misoprostol – in either a delayed or early abortion group.
