A comprehensive study by Artyom Gusarov found that soil erosion and river sediment load decreased significantly in European Russia. Climate change and warming of near-soil air led to reduced frosting and decreased erosion-inducing sediment from tillage in the steppes.
A group of patients with neurological disease have been found to lack a critical cell process called autophagy. This discovery challenges the understanding that humans cannot survive if their cells completely fail to carry out autophagy, and may have important implications for research and therapies in neurodegeneration and cancer.
A new algorithm developed at Caltech allows autonomous systems to recognize their location by analyzing the terrain around them, even in seasonal changes. The system uses self-supervised learning to identify patterns in images, resulting in more accurate localization, with 92% success rate compared to 50% with traditional techniques.
Life expectancy in the US decreased by nearly two years between 2018 and 2020, widening the gap with other high-income countries, especially among Hispanic and Black Americans. The largest declines were observed in these groups, with life expectancy falling by 15-18 times more than in peer countries.
Researchers discover that cryptochrome 4, found in birds' retinas, is sensitive to magnetic fields and could be the long-sought magnetic sensor. The team deciphered the mechanism behind this sensitivity, which arises from electrons moving within the molecule after blue-light activation.
Researchers at DZNE's Dresden site develop i3D-Markers, a cutting-edge technology platform that uses high-density microelectrode arrays and 3-dimensional neuronal networks to predict the reaction of neurons to compounds. This platform aims to optimize drug candidate selection and accelerate brain disease development.
EarthLab aims to simulate physical climate, environmental, and ecological systems for better predicting natural disasters and understanding Earth's spheres. The facility will enable researchers to predict Earth systems on a vast time and spatial scale.
A research team led by ECU's Natasha Bell has received a $1.2 million grant to overcome barriers to growth in North Carolina's aquaculture industry and strengthen wastewater infrastructure. The project aims to develop new ecological engineering treatment technologies, including hybrid constructed wetlands and novel 3D-printed materials.
A study published in Economic Inquiry examined data from 133 countries from 1950-2014, finding that reduced fiscal space in high-income countries after the 2007-2009 global financial crisis led to procyclical policy actions. This resulted in prolonged economic downturns and aggravated business cycle fluctuations.
A new study reveals that tropical rainfall clusters in the western Pacific contribute to East Antarctic summer cooling. The Madden-Julian Oscillation (MJO) plays a key role in this phenomenon, with MJO-related rainfall and pressure changes favoring cooling of East Antarctica.
A new study from Stanford University School of Medicine found that hospitalizations to treat pediatric gun injuries are expensive, with a total of about $109 million spent each year. The cost of hospitalizations rose over time, with more than half paid by Medicaid and uninsured patients accounting for 11% of all hospitalizations.
Researchers from Bentley University analyzed reader comments on two partisan news sites after a challenging news event, revealing obstacles to sense-making and breakdowns in deliberation. The study adds to the understanding of political discourse and polarization, highlighting the need for solutions to combat misinformation.
Researchers used functional MRI to understand how the brain's reward areas react to e-cigarette aerosols with and without flavor. For smokers, unflavored e-cigarettes may mimic the typical smoking experience more than flavored e-cigarettes.
A 29-year-old woman was hospitalized with sepsis 14 months after a dermal filler injection, revealing rare bacterial causes and increasing awareness of the need for cosmetic patients and healthcare professionals.
A new University of Kentucky study will examine the effects of flavored tobacco product restrictions on health disparities among communities of color, low-income populations, and youth. The research aims to inform community leaders about how policies can help eliminate health inequities.
A new AI model can quantify individual deviations from typical aging trajectories in patients with mild cognitive impairment, indicating potential for earlier diagnosis and treatment. The study found that the model's predicted age difference was significantly associated with cognitive decline and progression to Alzheimer's disease.
Researchers found that early British Antarctic expeditions fed their dogs inadequate amounts of Spratt's dog cakes, leading to desperation and hunger among the canine team members. The study suggests that the dogs required significantly more energy-rich food to sustain their high-energy activities.
Researchers discovered that SARS-CoV-2 produces microRNAs affecting individuals' respiratory systems and immune responses. Understanding these impacts may provide new insights into COVID-19 pathogenesis and treatment.
West Virginia University is part of a team awarded $17 million from the National Science Foundation to renew the NANOGrav Physics Frontiers Center. The center aims to detect gravitational waves using pulsar timing arrays and will advance research in fundamental physics.
A study examined changes in physician work hours and patterns during the COVID-19 pandemic, finding significant shifts in work activities. The researchers discovered that physicians reduced their work hours, with a notable increase in work-from-home activities.
A new study published in the Journal of the Association for Consumer Research posits that increased accessibility to anthropomorphized luck can lead consumers to pursue higher-risk financial behavior. The authors suggest that preferences for riskier options are driven by shared risk perceptions that may engender feelings of security.
