A new study found that homicides near schools decrease math test scores by 5% and attendance by 1%, with a similar effect to reducing teacher quality. Boys are more affected by violence than girls, leading to lower aspirations and attitudes towards education.
Researchers at Clemson University have identified two genetic variations associated with small body size and lance canine, a dental anomaly common in Shetland Sheepdogs. The study found that dogs with these variations are on average one inch shorter and six pounds lighter than unaffected breeds.
Researchers found that only 70.8% of children received any follow-up treatment for mental illness within the first three months, varying widely by ZIP code. Many children were prescribed strong drugs with little evidence of effectiveness, despite generally recommended therapy as a first line of treatment.
Researchers at Kiel University found that neglected magnetic interactions play a key role in stabilizing skyrmions, increasing their lifetime and opening up new material systems. The discovery could enhance the stability of skyrmions, enabling their use in future electronic devices and data storage concepts.
A new brief survey called the Brief Environmental Exposure and Sensitivity Inventory (BREESI) can help identify individuals with chemical intolerance by answering just three yes-or-no questions. The BREESI was developed to address the growing concern of chemical intolerance, which affects 8-33% of individuals, and its impact on health.
Researchers developed a new software tool called WhatsHap polyphase to phase plant genomes in high resolution and with low error margins. The tool solves the problem using a two-phase process and is now available for polyploid organisms, including plants.
A semi-automatic phone triage system designed to help people with chest discomfort during out-of-hours periods has been found to be unsafe and unreliable. The system underestimated the severity of more than a quarter of patients with serious heart conditions, highlighting the need for input from nurses to ensure accurate assessment.
Researchers measure CO2 concentration in the atmosphere and find no decrease despite estimated reductions of up to eight percent in 2020. Long-term changes are needed to reach Paris Climate Agreement goals, requiring cumulative reductions every year.
Researchers found that glucocorticoid therapy, even at low doses (5mg/day or less), significantly increases the risk of serious infections in rheumatoid arthritis (RA) patients. The study used claims data from over 200,000 patients with RA to show a 30% increase in infection risk among those on low-dose glucocorticoids.
Astrophysicists identify distinctive signatures of stellar-mass black holes in archival X-ray data, separating them from neutron stars. This is the strongest steady signature of stellar-mass black holes to date.
The team will investigate the molecular linkages between aging and Parkinson's, exploring whether decreasing senescence can slow or stop the disease. Genetic predisposition and age are critical factors in defining a person's risk for Parkinson's.
A US study found that middle-aged individuals without a bachelor's degree reported more pain than elderly individuals, unlike in other wealthy countries where pain rises with age. The finding suggests that pain prevalence will continue to increase for less-educated adults in the US, with significant implications for healthcare.
A new study published in Cancer found that Black women experience longer waits for treatment initiation and prolonged duration of treatment after a breast cancer diagnosis. The research, which analyzed data from over 2,800 participants, identified financial and transportation issues as key contributors to these delays.
Wilfred weakened into a trough in the Central Atlantic Ocean, with maximum sustained winds near 35 mph and forecasters expect winds to continue decreasing. The system's interaction with an upper-level trough led to linear thunderstorm development.
A new study suggests that concentrating tree planting efforts on understocked forest land, particularly in western states and the Northeast, can substantially increase carbon sequestration capacity. This targeted approach could enhance ecosystem services and offset a significant portion of the country's carbon dioxide emissions.
A new study confirms the existence of residual, non-functioning beta cells in living individuals with longstanding type 1 diabetes. Researchers used a non-invasive imaging technique to detect these cells, which may be restored if adequate treatments are available.
Researchers using SwRI instruments aboard the ESA's Rosetta spacecraft discovered a unique aurora at Comet 67P/Churyumov-Gerasimenko, revealing the comet's interaction with solar particles. The detection was made possible by integrating multi-instrument data, providing new insights into cometary auroras.
A novel measurement framework has been developed to track energy poverty more accurately, focusing on the services people lack rather than just physical connections. This alternative framework can aid in better tracking of Sustainable Development Goal 7 by virtue of its simplicity and sensitivity to diverse service conditions among the...
