A new study by San Francisco State University Professor Nara Jeong found that liberal CEOs invest more in socially conscious activities when they feel those values are threatened. Conversely, support for socially responsible initiatives drops among CEOs who share the same political beliefs as the president.
Researchers identify CD1a as a key player in triggering T cell responses to allergens in personal care products, shedding light on the 'molecular missing link' behind allergic contact dermatitis. The study highlights the importance of fragrance molecules like farnesol in initiating immune responses.
A new expert review confirms that diet significantly influences mental health and wellbeing. While some areas like ketogenic diets for epilepsy and Mediterranean diets show mental health benefits, many foods or supplements have inconclusive evidence.
Monash University researchers have developed the world's most efficient lithium-sulfur battery, with the potential to power smartphones for up to five days and electric vehicles for over 1,000km. The new battery design has attractive performance, lower manufacturing costs, and a reduced environmental footprint.
A new study found that chemicals in common skincare products can trigger allergic contact dermatitis by displacing natural lipids on skin cells. Researchers identified CD1a molecules as a key player in this process and discovered competing lipids that can displace triggering chemicals, potentially treating the condition.
Female chimpanzees' reproductive success decreases when neighboring groups exert high pressure on their territory, leading to longer intervals between births. High neighbor pressure also negatively affects offspring survival, suggesting that stress from competition triggers physiological responses in gestating females.
Researchers at Lobachevsky University and Ghent University found that immunogenic cell death can be used to enhance cancer therapy and prevent relapse. The study tested existing anti-cancer drugs with enhanced immunogenic properties, revealing potential new protocols for reducing metastasis and improving patient recovery.
A Yale study found that treating at least 20% of people with opioid use disorder who inject drugs in Ukraine could prevent over 10,000 new HIV infections and nearly 18,000 deaths. The current rate is only 2.7%, highlighting the need for expanded access to evidence-based treatment like methadone and buprenorphine.
A new tool called Contingent Organization-Public Relationships (COPR) measures an organization's relationship with its public stakeholders, accounting for the dynamic nature of relationships. The COPR framework assesses relationships based on stance and public discourse, categorizing them into six well-defined categories.
Researchers developed a mathematical framework to simulate molecular interactions, making it easier to develop new therapies. The study found that controlling three key parameters can affect how molecule chains interact, leading to new insights into disease mechanisms and potential treatments.
Researchers have discovered that freestanding gold clusters of twenty atoms take on a pyramidal shape with a triangular ground plane and additional triangles. The study reveals the cluster's unusual electronic structure, which is similar to noble gas atoms or aromatic molecules, making them less reactive.
The water lily genome expands the picture of the early evolution of flowering plants, shedding light on key traits like flower development and attractive floral scent. Researchers used high-throughput sequencing technology to analyze the genome and transcriptome of Nymphaea colorata, identifying over 31 thousand protein-coding genes.
The MDI Biological Laboratory is expanding its SEPA program to assess seasonal variations of arsenic in well water. The program aims to improve public health and stimulate interest in STEM fields among secondary school students through citizen science engagement.
The global low-carbon revolution faces a significant threat unless new governance mechanisms are established to ensure a sustainable supply of rare minerals and metals. The extraction and processing of these materials poses environmental and social risks, and their growing demand could lead to shortages and market instability.
A new study has found an association between exposure to air pollution and poor bone health. Fine particles in the air were linked to lower levels of bone mass, while biomass fuel use was not correlated. The study's findings contribute to a growing body of evidence on the impact of particulate air pollution on bone health.
A recent study found a 50% increase in total mortality and three-fold increase in heart disease deaths in individuals with high 3-PBA levels, a metabolite of pyrethroids. The study's findings challenge the assumption that these insecticides are safe, particularly for vulnerable populations.
A team of physicists at Penn State and Germany's University of Wurzburg studied over three dozen devices similar to the one used to produce the angel particle. They found that the feature claimed to be the manifestation of the angel particle was unlikely to be induced by its existence.
Researchers describe the current state of metal toxicity modeling and science-based best practices for water chemistry. The latest models support improved ecosystem protection, but outdated regulations remain a concern.
Scientists developed a novel method to create zebrafish with conditional gene knockout and knock-in switches in one step. The strategy uses CRISPR/Cas9-mediated non-HR insertion, allowing for efficient targeting of specific genes and the creation of reporter lines with fluorescent markers.
Children aged 10-12 were nearly three times more likely to make healthy eating decisions after watching a TV cooking program featuring healthy food. The study found that children who watched the healthy program were far more likely to choose a healthy snack option, an apple or cucumber.
Researchers identified changes in neural circuits supporting executive function and self-control during adolescence, finding that complex brain areas like the prefrontal cortex develop later and have higher structure-function coupling, leading to improved cognitive abilities.
A study published in Scientific Reports found that microbes from humic lakes can transform polyethylene into beneficial fatty acids, including omega-3 and omega-6. This discovery suggests that microplastic degradation may be more pronounced in certain environments than previously thought.
A new type of metalens made from a dielectric-metal composite film can overcome diffraction limits, paving the way for high-resolution nanoscale optical technologies and sensors. The ultra-high resolution is achieved through an unusual behavior of the material in optical and infrared ranges.
A recent study found that oral infections are not linked to increased risk of death or serious infection after stem cell transplantation. The researchers suggest that conservative dental treatment may be sufficient for patients with asymptomatic dental infections, and radical treatment is only necessary in specific cases.
A team of meteorologists found no consistent evidence for decadal oscillatory signals in global surface temperature observations. The researchers suggest that any apparent oscillation may be due to external influences like greenhouse gas and aerosol emissions. The study has implications for decade-scale climate predictability.
Two Harvard Medical School studies show that bile acids promote differentiation and activity of T cells involved in regulating inflammation. Gut microbes convert bile acids into immune-signaling molecules that activate regulatory T cells and effector helper T cells. The work suggests possible therapeutic pathways for modulating intesti...
China's inland surface water quality improved significantly from 2003-2017 due to reduced pollution emissions in industrial, rural, and urban residential sectors. Annual mean concentrations of chemical oxygen demand and ammonium nitrogen declined by 63% and 78%, respectively, at the national level.
Researchers developed an adeno-associated virus vector to deliver anti-pTau antibodies directly into the hippocampus of mouse models with CTE, reducing pTau levels across the CNS. The study suggests this strategy could be effective in humans and may offer a new treatment option for CTE.
