ITHACA, N.Y. -- Volcanic ash is no ordinary dust: It gets injected into the atmosphere, climbs to the stratosphere, impacts climate, powders roadways and clogs jet engines. To bridge the knowledge gap between volcanologists and atmospheric scientists working on climate change and observing global systems, Cornell researchers have characterized volcanic ash samples from many explosive eruptions of a broad compositional range. The work is helping scientists uncover how this tiny material – measured in microns and nanometers – plays a big role in the atmosphere. Volcanic ash is formed from minerals trapped in ...

Cancer immunotherapy drugs called PD-1 inhibitors are widely used to stimulate the immune system to fight cancer, but many patients either don’t respond or develop resistance to them. A new small-molecule drug candidate being tested in an early-stage clinical trial aims to improve patient responses to immunotherapy.  Now scientists have shown, in a study published today in Nature, that the small molecule works through two different mechanisms to slow tumor growth and increase survival in lab animals.  Researchers from the Tumor ...

In a study on the prevalence of attention-deficit/hyperactivity disorder (ADHD) and its association with crash risk among older adult drivers, researchers at Columbia University Mailman School of Public Health found that older adult drivers with ADHD are at a significantly elevated crash risk compared with their counterparts without ADHD. Outcomes included hard- braking events, and self-reported traffic ticket events, and vehicular crashes. Until now research on ADHD and driving safety was largely limited to ...

About The Study: This study found that the burden of respiratory syncytial virus (RSV)-associated hospitalizations in Canadian pediatric hospitals was substantial, particularly among infants less than six months of age, and RSV hospitalizations increased in 2021-2022 compared with the pre-pandemic period, while severity of illness remained similar. These findings suggest that RSV preventive strategies for infants less than six months of age would be associated with decreased RSV disease burden in children.  Authors: Jesse Papenburg, ...

About The Study: Based on U.S. national representative data, the estimated attention-deficit hyperactivity disorder (ADHD) prevalence was 10.08% to 10.47% among children and adolescents ages 4 to 17 from 2017 to 2022, which was similar to the prevalence from the National Health Interview Survey in 2015 to 2016 (10.20%). No significant annual change in the prevalence of ADHD was found from 2017 to 2022. Notably, the estimated prevalence of ADHD among individuals in the U.S. in this study was higher than worldwide estimates (5.3%) in earlier years (1978-2005). Authors: Wenhan Yang, M.D., Ph.D., of Guangdong ...

About The Study: In this post hoc secondary analysis of 10,678 participants with atherosclerotic cardiovascular disease from a randomized clinical trial, enteric-coated aspirin was not associated with significantly higher risk of heart attack, stroke, or death or with lower bleeding risk compared with uncoated aspirin, regardless of dose, although a reduction in bleeding with enteric-coated aspirin cannot be excluded. More research is needed to confirm whether enteric-coated aspirin formulations or newer formulations will improve outcomes in this population. Authors: Mark B. Effron, M.D., of the University of Queensland-Ochsner Clinical School in New Orleans, is the corresponding ...

Robots built by engineers at the University of California San Diego helped achieve a major breakthrough in understanding how insect flight evolved, described in the Oct. 4, 2023 issue of the journal Nature. The study is a result of a six-year long collaboration between roboticists at UC San Diego and biophysicists at the Georgia Institute of Technology.  The findings focus on how the two different modes of flight evolved in insects.

Main points: New research has overturned the traditional view that natural rock weathering acts as a CO2 sink that removes CO2 from the atmosphere. Instead, this can also act as a large CO2 source, rivalling that of volcanoes. The results have important implications for modelling climate change scenarios but at the moment, CO2 release from rock weathering is not captured in climate modelling. Future work will focus on whether human activities may be increasing CO2 release from rock weathering, and how this could be managed. A new study led by the University of Oxford has overturned the view ...

Philadelphia, October 2, 2023 – Researchers from the Center for Injury Research and Prevention (CIRP) at Children’s Hospital of Philadelphia (CHOP) and the Stuart Weitzman School of Design at the University of Pennsylvania have found that teenagers living in lower-income areas of the Columbus, Ohio metro area are up to four times less likely to complete driver training and obtain their driver’s license before age 18. Long travel times to driving schools also impacted enrollment in driver education, affecting those from both higher- and lower-income areas. The findings, originally published in the journals Accident Analysis and Prevention ...

Researchers at Vanderbilt-Ingram Cancer Center have discovered a druggable target on natural killer cells that could potentially trigger a therapeutic response in patients with immunotherapy-resistant, triple-negative breast cancer. Currently, only about 15% of early-stage, triple-negative breast cancer patients benefit from combining immunotherapy, drugs that target immune cells to attack the tumor, with chemotherapy. Identifying why most patients don’t respond is critical for personalizing treatment plans and minimizing therapy ...

Researchers have discovered a sea’s worth of water locked within the sediment and rock of a lost volcanic plateau that’s now deep in the Earth’s crust. Revealed by a 3D seismic image, the water lies two miles under the ocean floor off the coast of New Zealand, where it may be dampening a major earthquake fault that faces the country’s North Island. The fault is known for producing slow-motion earthquakes, called slow slip events. These can release pent-up tectonic pressure harmlessly over days and weeks. Scientists want to know why they happen more often at some ...

A door-to-balloon (D2B) time of 90-minutes or less is associated with improved outcomes for heart attack patients. However, during the COVID-19 pandemic certain obstacles—including the need for COVID-19 screening, associated isolation procedures and terminal cleaning in the cardiac cath lab—led to increased D2B times. According to a new study, presented at the American College of Cardiology (ACC) Quality Summit 2023, many health care facilities are still recovering from the pandemic and facing new challenges, causing D2B times to continue to lag. A myocardial infarction, or heart attack, occurs when there has been a blockage ...

Developing brains become shaped by the sights, sounds, and experiences of early life. The brain’s circuits grow more stable as we age. However, some experiences later in life open up opportunities for these circuits to be rapidly rewired. New research from Cold Spring Harbor Laboratory Associate Professor Stephen Shea helps explain how the brain adapts during a critical period of adulthood: the time when new mothers learn to care for their young. Shea’s work in mice shows how this learning process ...
