A Response to the Decision to Rescind EPA’s 2009 Endangerment Finding The American Meteorological Society (AMS) is deeply concerned by the repeal of EPA’s 2009 Endangerment Finding, which correctly concluded that greenhouse gas emissions harm health and well-being for current and future generations.  AMS reaffirms key scientific conclusions of climate change that relate to the Endangerment Finding: 1. The impacts of climate change are harmful to people ...

“Like father, like son? Can parenting styles break the intergenerational pattern of alcohol and drug use?” A group of Brazilian researchers analyzed data on the behavior of 4,280 adolescents and their guardians based on this question, arriving at two important conclusions. Yes, parental attitudes are one of the most relevant factors in preventing alcohol and drug use among young people. However, the way guardians educate their children can significantly mitigate the risk, even in families where caregivers use these substances, including cigarettes, vapes (which are banned in Brazil), and marijuana. The reduction in risk is more significant when the relationship ...

The research team led by Hanmin Huang and Bangkui Yu at the University of Science and Technology of China developed a palladium-catalyzed diastereoselective and enantioselective cascade cyclization strategy, achieving the modular synthesis of chiral nitrogen-bridged ring skeletons. Using readily available salicylaldehyde and aminodiene as starting materials, and based on the team's previously developed strategy of "in-situ generation of three-membered ring palladium active intermediates from aldehydes and amines," the bridged oxazole bicyclic compounds were constructed with high diastereoselectivity ...

A new pilot study examining how immigrant residents engage with city services and government processes in Long Beach suggests that heightened federal immigration enforcement is undermining democratic participation, even among U.S. citizens who fear for undocumented family members. The pilot research, conducted by UC Irvine scholars in partnership with three Long Beach community organizations (Filipino Migrant Center, Latinos in Action California, and United Cambodian Community of Long Beach), interviewed 24 Cambodian, Filipino, ...

The American Meteorological Society continuously publishes research on climate, weather, and water in its 12 journals. Many of these articles are available for early online access–they are peer-reviewed, but not yet in their final published form. Below are some recent examples of online and early-online research. JOURNAL ARTICLES What follows are summaries which have not been peer-reviewed or vetted by the article authors; read the full article for peer-reviewed conclusions. Please note that no single study is ever definitive, and each must be taken in the context of the broader scientific literature. ...

Deforestation in the Amazon is causing significant regional changes in climate compared to areas with forest cover above 80%. The loss of vegetation leads to an increase in surface temperature, a decrease in evapotranspiration, and a reduction in precipitation during the dry season and in the number of rainy days. The results are part of a study based on satellite data published in late November in the journal Communications Earth & Environment. The study points out that highly deforested regions (with forest cover below 60%) share climatic similarities with areas of transition between rainforest ...

Brazilian researchers have developed a methodology that uses remote sensing to map the impact of frost on corn crops. This reduces exposure to climate risks and uncertainty regarding agricultural losses. The model allows users to customize a set of variables, making it useful for other crops in different agricultural contexts. Thus, it has the potential to provide more accurate estimates during harvests and contribute to the development of public policies that support production chains and insurance systems. Global grain production, ...

Humans develop sharp vision during early fetal development thanks to an interplay between a vitamin A derivative and thyroid hormones in the retina, Johns Hopkins University scientists have found.   The findings could upend decades of conventional understanding of how the eye grows light-sensing cells and could inform new research into treatments for macular degeneration, glaucoma, and other age-related vision disorders.  Details of the study, which used lab-grown retinal tissue, ...

UNIVERSITY PARK, Pa. — Biting into a tart green apple is a different taste and sensory experience than sucking juice from a lemon — and both significantly vary from accidentally consuming spoiled milk. Each of these foods contains a different organic acid that gives rise to the flavor commonly referred to as “sour,” even when the taste and related mouthfeel sensations such as puckering and drying vary drastically from food to food and person to person. Now, Penn State researchers have found that while some of that difference comes from individual perceptions, the acids themselves vary in sourness, even at the same concentrations. The researchers, ...

One of the world’s largest cross-disciplinary science gatherings, the AAAS meeting is a key venue for debate about how emerging technologies should be governed. Tsosie’s presentation examines how Indigenous science offers frameworks for equity, accountability, and stewardship as genomics, artificial intelligence, and precision health ...

Scientists have traditionally studied how the brain controls movement by asking patients to perform structured tasks while connected to multiple sensors in a lab. While these studies have provided important insights, these experiments do not fully capture how the brain functions during everyday activities, be it walking to the kitchen for a snack or strolling through a park. For people living with Parkinson’s disease, this gap between laboratory research and real-world behavior has limited efforts to improve gait symptoms outside of the clinic.  Now, ...

About The Study: Prior research finds abortion restrictions are associated with increased demand for telehealth medication abortion. However, whether this trend extended to adolescents was previously unknown, a population facing the unique legal burden of mandatory parental involvement, in addition to gestation bans. This study found that post-Dobbs increases in requests were highest among young adults, especially in states with restrictive abortion laws, and among adolescents, in states with gestational bans and parental consent and notification requirements. Corresponding Author: To contact the ...

COLUMBUS, Ohio – Off-putting smells can make even the healthiest of foods unpalatable.  In a new study, researchers have developed a way to remove unpleasant aromas from plant-based proteins to make them smell more appealing. They did so by designing a two-step fermentation process to counter the odors that typically form during cultivation and extraction.  The study’s results showed that their approach could remove between 95 to 99% of key smells, significantly outperforming one-stage fermentation ...

With a few minutes of searching, anyone can find videos online of chatty birds: macaws talk to their keepers, cockatoos sing to the camera, corvids mimic the jarring sounds of construction sites.   Research has shown that some birds can understand and use words in context — so, when Polly speaks up from inside her cage, she may really want a cracker — but scientists know far less about how birds use their vocal abilities in the wild. Christine Dahlin, professor of biology at the University ...

Manufacturing next-generation solar panels could cut global carbon emissions by up to 8.2 billion tonnes by 2035, finds a new international study by researchers from the University of Warwick and Northumbria, Birmingham, and Oxford Universities. Solar panels, known scientifically as photovoltaics (PV), convert sunlight directly into electricity and are central to global decarbonisation. But as countries race to deploy solar at multi-terawatt scale, the carbon footprint of manufacturing these devices is coming under increasing scrutiny. At the same time, the industry is rapidly shifting from the current industry-standard ...

Temporal lobe epilepsy (TLE) is the most common form of focal epilepsy, affecting a significant proportion of patients who develop drug-resistant epilepsy. Surgical interventions, particularly stereoelectroencephalography (SEEG)-guided temporal lobe resection (TLR) and SEEG-guided responsive neurostimulation (RNS), have emerged as pivotal treatment options. This systematic review aims to compare the efficacy, safety, and quality of life (QoL) outcomes associated with these two interventions in adults with drug-resistant TLE. The review followed the PRISMA 2020 ...

Background and objectives Cardiac pacemaker implantation is a primary therapy for various arrhythmic disorders; however, safety concerns persist in India. This study aimed to evaluate two-year safety outcomes of cardiac pacemakers, implantable cardioverter-defibrillators, and cardiac resynchronization therapy devices in a tertiary care setting. Methods In this prospective cohort study, data collection was conducted over a one-year enrolment period (February 2023 to January 2024), encompassing patient demographics, pacemaker implantation details, indications, and comorbidities. Patients were prospectively followed for a total of two years from enrolment—during the ...

G-protein-coupled receptors (GPCRs) are one of the largest families of cell surface proteins in the human body that recognize hormones, neurotransmitters, and drugs. These receptors regulate a wide range of physiological processes and are the targets of more than 30% of currently marketed drugs. The histamine H1 receptor (H1R) is one such GPCR subtype that plays a key role in mediating allergic reactions, inflammation, vascular permeability, airway constriction, wakefulness, and cognitive functions in the human body. While antihistamines primarily target H1R, current drugs can exhibit limited therapeutic efficacy, prompting researchers to look at H1R ligands from new perspectives. Recently, ...

Weight loss is a well-recognized but poorly understood non-motor feature of Parkinson’s disease (PD). Many patients progressively lose weight as the disease advances, often alongside worsening motor symptoms and quality of life. Until now, it was unclear whether this reflected muscle loss, poor nutrition, or deeper metabolic changes. New research shows that PD-related weight loss is driven mainly by a selective loss of body fat, while muscle mass is largely preserved, and is accompanied by a fundamental shift in how the body produces energy. Although PD is classically viewed as a neurological disorder, increasing evidence points to widespread ...

In two new studies on 28,000 individuals, researchers are able to show that genetic variants in 11 regions of the human genome have a clear influence on which bacteria are in the gut and what they do there. Only two genetic regions were previously known. Some of the new genetic variants can be linked to an increased risk of gluten intolerance, haemorrhoids and cardiovascular diseases. The community of bacteria living in our gut, or gut microbiome, has become a hot research area in recent years because of its great significance for health and disease. However, the extent ...
