Study finds gunshots in American cities twice as likely at night, potentially disrupting sleep for those in earshot

A new study found that nighttime gunshots are twice as common as daytime gunshots in American cities, potentially disrupting the sleep of nearby residents due to loud sirens. Low-income neighborhoods are disproportionately affected by these sounds, with millions of person nights potentially impacted annually.

Enhancing hypoxia-activated prodrug anticancer therapy: amplified active targeting, enhanced drug activation, and increased hypoxic cytotoxicity

Scientists have developed a new universal nanosystem to enhance the efficacy of tirapazamine (TPZ) in cancer treatment. The system combines a tumor microenvironment remodeling agent with a TPZ derivative, resulting in increased hypoxic cytotoxicity and improved targeting ability.

New study finds triple-negative breast cancer tumors with an increase in immune cells have lower risk of recurrence after surgery

A new study suggests that early-stage triple-negative breast cancer (TNBC) patients with high levels of immune cells in their tumors may have a lower risk of recurrence and better survival rates even without chemotherapy. Higher TILs in breast cancer tissue were associated with lower recurrence rates among participants.

Want to cut US heart risks? Get more people into primary care, study suggests

A new study suggests that most essential care for cardiovascular health happens in general primary care clinics, but many at high risk don't receive it. The study found that large percentages of people with major cardiovascular risk factors didn't see a primary care provider or cardiologist in the past year.

Why don't we stick to home physiotherapy exercises?

Researchers from Ben-Gurion University of the Negev identified six barriers to consistent home physiotherapy exercises in vestibular rehabilitation, including motivation, increased symptoms, and psychosocial factors. The study offers actionable recommendations for clinicians to overcome these barriers and improve treatment outcomes.

A molecular route to decoding synaptic specificity and nerve cell communication

A team of researchers from Tokyo Institute of Technology identified the molecular mechanisms involved in synaptic communication using Drosophila. They found that Side-IV/Beat-IIb immunoglobulin superfamily protein molecules play a crucial role in inducing synapse formation and regulating preferential signaling among neuron pairs.

Far-UVC light can virtually eliminate airborne virus in an occupied room

A new study shows that far-UVC light can virtually eliminate airborne viruses in occupied work environments, reducing infectious airborne virus levels by 99.8%. The technology has the potential to provide more protection against airborne-disease transmission than ventilation systems, making it a promising solution for indoor spaces.

A new 'Deep Learning' model predicts with great accuracy water and energy demands in Agriculture

A new Deep Learning model based on the Transformer architecture has been developed to predict water and energy demands in agriculture. The model forecasts daily demand for irrigation water seven days in advance with an error margin of less than 2%, enabling effective resource management without autonomy loss.

Methods sections often lack critical details needed to reproduce an experiment, and the practice of citing previous papers instead of describing the methods in detail may contribute to this problem

A recent analysis of over 750 papers found that more than 90% rely on shortcut citations in their methods sections, significantly impeding the ability to reconstruct original experiments. This practice is prevalent across journals, with less than a quarter adhering to policies governing previously described methods.

Stressful events in midlife might be a risk factor for Alzheimer's disease in older ages

A recent study published in Annals of Neurology suggests that midlife stressful events may be a risk factor for developing Alzheimer's disease in older ages. Researchers found associations between stress and higher levels of beta-amyloid protein, neuroinflammation, and brain atrophy, particularly in men.

Corn reduces arsenic toxicity in soil

A study by the University of Basel found that corn plants release benzoxazinoids, which reduce arsenic uptake and mitigate toxicity. This mechanism could be used to cultivate hyper-emitting plant varieties for arsenic-contaminated locations, reducing food chain contamination.

Companies ignoring climate risks get punished by markets, new study reveals

A recent study from the University of Florida found that companies ignoring climate risks tend to face market penalties, whereas those proactively managing risks fare better. The research analyzed textual data from nearly 5,000 US public companies and discovered a costly divide between proactive and non-proactive firms.

Lung cancer does not decrease in line with reduced smoking

A new study from Umeå University found that lung cancer rates haven't decreased as expected with reduced smoking. Despite declining smoking rates, the number of cases of lung cancer has increased, especially among women. The study suggests that previous assumptions about the quick decrease in risk after quitting may have been exaggerated.
