Science doesn't understand how ice forms (video)

Science doesn't understand how ice forms (video)
2024-05-06
(Press-News.org) WASHINGTON, May 6, 2024 — This video contains incredible macro footage of supercooled water droplets nucleating ice. All George wanted to do was make a crystal-clear ice cube. Instead, he ended up rediscovering dendritic crystal growth, a beautiful phenomenon first described in the 17th century. You’ll never look at your freezer the same way again. https://youtu.be/24TB1vPuzIU?feature=shared

The American Chemical Society (ACS) is a nonprofit organization chartered by the U.S. Congress. ACS’ mission is to advance the broader chemistry enterprise and its practitioners for the benefit of Earth and all its people. The Society is a global leader in promoting excellence in science education and providing access to chemistry-related information and research through its multiple research solutions, peer-reviewed journals, scientific conferences, eBooks and weekly news periodical Chemical & Engineering News. ACS journals are among the most cited, most trusted and most read within the scientific literature; however, ACS itself does not conduct chemical research. As a leader in scientific information solutions, its CAS division partners with global innovators to accelerate breakthroughs by curating, connecting and analyzing the world’s scientific knowledge. ACS’ main offices are in Washington, D.C., and Columbus, Ohio.

Study reveals APOE4 gene duplication as a new genetic form of Alzheimer's disease

Study reveals APOE4 gene duplication as a new genetic form of Alzheimers disease
2024-05-06
Researchers from the Research Area on Neurological Diseases, Neuroscience, and Mental Health at the Sant Pau Research Institute, led by Dr. Juan Fortea, Director of the Memory Unit of the Neurology Service at the same hospital, have found that over 95% of individuals over 65 years old who have two copies of the APOE4 gene -APOE4 homozygotes- show biological characteristics of Alzheimer's pathology in the brain or biomarkers of this disease in cerebrospinal fluid and PET scans. The study, published today in Nature Medicine, also concludes that those individuals homozygous for APOE4 also develop ...

Study highlights key predictors of adolescent substance use; special issue of the American Journal of Psychiatry focuses on substance use disorders

2024-05-06
  NEW YORK, May 6, 2024 – New research, published online today in the American Journal of Psychiatry, examined a broad range of potential predictors of substance use among adolescents and found sociodemographic variables were the most robust predictors of substance use initiation. The study is part of a special issue of the journal highlighting advances in understanding the neurobiology and sociodemographic underpinnings of substance use disorders and how this understanding has advanced recognition and treatment. Several authors discussed this work today at a special briefing during the 2024 Annual Meeting of the American Psychiatric ...

Racial and ethnic disparities in initiation of direct oral anticoagulants among Medicare beneficiaries

2024-05-06
About The Study: In this cohort study of Medicare patients with atrial fibrillation, Black and Hispanic patients were less likely to initiate direct oral anticoagulants for atrial fibrillation, although these differences diminished over time. Identifying the factors behind these early disparities is crucial for ensuring equitable access to novel therapies as they emerge for Black and Hispanic populations.  Corresponding Authors: To contact the corresponding authors, email Kamika R. Reynolds, M.S., Ph.D. (kreynolds@ifh.rutgers.edu) and Chintan ...

Behavioral interventions to improve breast cancer screening outreach

2024-05-06
About The Study: These findings show that text messaging women after initial breast cancer screening outreach via either electronic portal or mailings, as well as bulk ordering with or without text messaging, can increase mammogram completion rates.   Corresponding Author: To contact the corresponding author Shivan J. Mehta, M.D., M.B.A., M.S.H.P., email shivan.mehta@pennmedicine.upenn.edu.

Venus has almost no water. A new study may reveal why

Venus has almost no water. A new study may reveal why
2024-05-06
Planetary scientists at the University of Colorado Boulder have discovered how Venus, Earth’s scalding and uninhabitable neighbor, became so dry. The new study fills in a big gap in what the researchers call “the water story on Venus.” Using computer simulations, the team found that hydrogen atoms in the planet’s atmosphere go whizzing into space through a process known as “dissociative recombination”—causing Venus to lose roughly twice as much water every day compared to previous estimates. The team will publish their findings May 6 in ...

DDT pollutants found in deep sea fish off Los Angeles coast

DDT pollutants found in deep sea fish off Los Angeles coast
2024-05-06
In the 1940s and 1950s, the ocean off the coast of Los Angeles was a dumping ground for the nation’s largest manufacturer of the pesticide DDT – a chemical now known to harm humans and wildlife. Due to the stubborn chemistry of DDT and its toxic breakdown products, this pollution continues to plague L.A.’s coastal waters more than half a century later. While legal at the time, details of this industrial-scale pollution of the marine environment at a dump site some 15 miles offshore near Catalina Island ...

Turbid waters keep the coast healthy

Turbid waters keep the coast healthy
2024-05-06
Turbid waters keep the coast healthy To preserve the important intertidal areas and salt marshes off our coasts for the future, we need more turbid water. That is one of the striking conclusions from a new study conducted by a Dutch-Chinese team of researchers and published today in Nature Geoscience."These natural areas outside our dikes are essential for nature and coastal defense. But because how we are now building in the Delta and the hinterland, coastal defense is endangered in the long term," warns NIOZ researcher Tim Grandjean.   Satellite measurements For his research, Grandjean linked decades of satellite measurements ...

Microscopic heart vessels imaged in super-resolution for first time at Imperial

2024-05-06
A new imaging technique tested in patients could improve the evaluation of cardiac conditions and undiagnosed chest pain. Researchers from Imperial College London’s Department of Bioengineering and Faculty of Medicine worked alongside academics from UCL to produce sub-millimetre resolution images of cardiac micro-vessels. The non-invasive new imaging technique was tested on four human patients. Existing imaging technologies can visualise large vessels on the heart’s surface. However, this new technique could allow scientists to study the physiology of the heart in more detail by imaging smaller micro-vessels within the heart muscle. This research, ...

Clinical trial shows that cytisinicline can help people quit vaping

2024-05-06
BOSTON–Eleven million U.S. adults use e-cigarettes to vape nicotine, and about half of them say that they want to stop, but many have trouble doing so because nicotine is an addictive drug. A plant-based medication called cytisinicline may be an effective therapy to help them stop vaping, according to the results of a new clinical trial co-led by an investigator from Massachusetts General Hospital, a founding member of the Mass General Brigham healthcare system. The trial’s findings are published in JAMA Internal Medicine. In the double-blind randomized clinical trial, 160 adults who vaped nicotine ...

Groundbreaking microcapacitors could power chips of the future

Groundbreaking microcapacitors could power chips of the future
2024-05-06
– By Alison Hatt In the ongoing quest to make electronic devices ever smaller and more energy efficient, researchers want to bring energy storage directly onto microchips, reducing the losses incurred when power is transported between various device components. To be effective, on-chip energy storage must be able to store a large amount of energy in a very small space and deliver it quickly when needed – requirements that can’t be met with existing technologies.  Addressing this challenge, scientists ...
