JAMA Network Open

2023-11-21

(Press-News.org) About The Study: In this study of 7,000 older U.S. residents, food insecurity was associated with increased dementia risk, poorer memory function, and faster memory decline. Future studies are needed to examine whether addressing food insecurity may benefit brain health.

Authors: Aayush Khadka, Ph.D., of the University of California, San Francisco, is the corresponding author.

Study highlights need to keep an eye on the ozone hole

2023-11-21

Despite public perception, the Antarctic ozone hole has been remarkably massive and long-lived over the past four years, University of Otago researchers believe chlorofluorocarbons (CFCs) aren’t the only things to blame. In a study, just published in Nature Communications, the group analysed the monthly and daily ozone changes, at different altitudes and latitudes within the Antarctic ozone hole, from 2004 to 2022. Lead author Hannah Kessenich, PhD candidate in the Department of ...

Scientists take a step forward in understanding how to tackle chronic infections in cystic fibrosis patients

2023-11-21

Scientists have engineered a living material resembling human phlegm, which will help them to better understand how a certain kind of infection develops on the lungs of patients with cystic fibrosis. The study, published in Matter, was led by Dr Yuanhao Wu and is a collaboration between Professor Alvaro Mata in the School of Pharmacy and Department of Chemical Engineering and Professor Miguel Cámara from the National Biofilms Innovation Centre in the School of Life Sciences at the University of Nottingham. Biofilms are strong living 3D materials that play ...

BU study finds long-term acute care hospital closures associated with changes in hospital care practices

2023-11-21

EMBARGOED by JAMA Network Open until 11 am, ET, Nov. 21, 2023 Contact: Gina DiGravio, 617-358-7838, ginad@bu.edu BU Study Finds Long-term Acute Care Hospital Closures Associated with Changes in Hospital Care Practices (Boston)—Long-term acute care hospitals (LTCHs) are common sites of post-acute care for patients recovering from severe respiratory failure requiring long-term mechanical ventilation. Because of longer lengths of stay compared to regular, short-stay hospitals, the Centers for Medicare and Medicaid (CMS) reimburses LTCHs at higher rates. However, since 2005, ...

How do we learn? Neuroscientists pinpoint how memories are likely to be stored in the brain

2023-11-21

What is the mechanism that allows our brains to incorporate new information about the world, and form memories? New work by a team of neuroscientists led by Dr Tomás Ryan from Trinity College Dublin shows that learning occurs through the continuous formation of new connectivity patterns between specific engram cells in different regions of the brain. Whether on purpose, incidentally, or simply by accident, we are constantly learning and so our brains are constantly changing. When we navigate the world, interact with each other, or consume media content, our brain is grasping ...

Bone growth drug may reduce sudden infant death syndrome in children with common form of dwarfism

2023-11-21

A drug that boosts bone growth in children with the most common form of dwarfism, may also reduce their chances of sudden infant death syndrome, sleep apnoea and needing surgery, according to a new study. The international research trial, led by Murdoch Children’s Research Institute (MCRI) and published in The Lancet Child & Adolescent Health, has showed for the first time that vosoritide treatment increases height, facial volume and the size of the foramen magnum, the hole at the base of the skull that connects the brain with the spinal cord, in children under five with achondroplasia. MCRI is the largest vosoritide ...

Density matters for better battery material performance, researchers find

2023-11-21

Zinc — cheap, abundant, environmentally friendly — may be the answer to better batteries, but there’s a major problem: Aqueous zinc ion batteries (AZIBs) cannot match lithium-ion batteries in terms of power output. To test what electrode material composition might be able to bring AZIBs up to par, a research team based in China developed two organic frameworks with the same constituents but arranged in different ways. When put to the test, the framework with appropriate density of active sites — where the zinc ions gain electrons to recharge the ...

AHRI and BGI Genomics sign MoU to enhance public health outcomes in Ethiopia

2023-11-21

On October 13, 2023, in Addis Ababa, Armauer Hansen Research Institute (AHRI) and BGI Genomics signed a Memorandum of Understanding to enhance the Institute's genomics and precision medicine capabilities. The Institute got its name from the Norwegian physician, Gerhard Henrik Armauer Hansen, who first described the leprosy bacillus (Mycobacterium leprae) and joined the Ethiopian Ministry of Health in 2004. Located in Addis Ababa, it serves as a biomedical hub for the region. BGI Genomics provides ...

Unraveling autism spectrum disorder mechanisms through rigid-autonomous phase sequences

2023-11-21

This study delves into the behavioral complexities of autism spectrum disorder (ASD) by introducing the rigid-autonomous phase sequence (RAPS) formation concept. RAPS are may be responsible for the cognitive, sensory-motor, and memory-related challenges faced by individuals with ASD. By uniting these insights under a single theoretical framework, this research paves the way for innovative treatments, promising a brighter future for those with ASD. Autism spectrum disorder (ASD) is a complex neuropsychiatric condition, marked ...

CSHL rolls out STEM ‘Bicycle Principles’

2023-11-21

Success in science, technology, engineering, and mathematics (STEM) demands keeping up with the latest tools and techniques. The AI boom, for example, has made coding and data management skills integral. But going back to school isn’t an option for most scientists. Short training programs like webinars and boot camps have become a popular alternative among busy STEM professionals. However, these formats can have significant shortcomings. There’s often no guarantee attendees will leave with the skills needed to advance their careers. And they can be exclusionary, preventing learners of all abilities and circumstances from benefiting equally. “We’ve ...

Coffee grounds may hold key to preventing neurodegenerative diseases

2023-11-21

EL PASO, Texas (Nov. 21, 2023) – Neurodegenerative disorders, including Alzheimer’s, Parkinson’s and Huntington’s, affect millions of people in the United States, and the cost of caring for people who live with these conditions adds up to hundreds of billions of dollars each year. Now, researchers from The University of Texas at El Paso may potentially have found a solution in used coffee grounds — a material that is discarded from homes and businesses around the world every day. A team led by Jyotish Kumar, a doctoral student in the Department of Chemistry and Biochemistry, and overseen by Mahesh ...
