NEW YORK, NY — The brain can direct the immune system to an unexpected degree, capable of detecting, ramping up and tamping down inflammation, shows a new study in mice from researchers at Columbia's Zuckerman Institute. "The brain is the center of our thoughts, emotions, memories and feelings," said Hao Jin, PhD, a co-first author of the study published online today in Nature. "Thanks to great advances in circuit tracking and single-cell technology, we now know the brain does far more than that. It is monitoring the function of every system in the body." Future ...

A University of Queensland researcher has found molecular doorways that could be used to help deliver drugs into the brain to treat neurological disorders. Dr Rosemary Cater from UQ’s Institute for Molecular Bioscience led a team which discovered that an essential nutrient called choline is transported into the brain by a protein called FLVCR2. “Choline is a vitamin-like nutrient that is essential for many important functions in the body, particularly for brain development,” Dr Cater said. “We need to consume 400-500 mg of choline ...

During sleep, the brain weakens the new connections between neurons that had been forged while awake – but only during the first half of a night’s sleep, according to a new study in fish by UCL scientists. The researchers say their findings, published in Nature, provide insight into the role of sleep, but still leave an open question around what function the latter half of a night’s sleep serves. The researchers say the study supports the Synaptic Homeostasis Hypothesis, a key theory on the purpose of sleep which proposes that sleeping acts as a reset for the brain. Lead author Professor Jason Rihel (UCL Cell & Developmental Biology) said: “When we are awake, ...

DALLAS (SMU) – An SMU-led research team has found that ancient rocks and fossils from long-extinct marine reptiles in Angola clearly show a key part of Earth’s past – the splitting of South America and Africa and the subsequent formation of the South Atlantic Ocean.  With their easily visualized “jigsaw-puzzle fit,” it has long been known that the western coast of Africa and the eastern coast of South America once nestled together in the supercontinent Gondwana — which broke off from the larger landmass of Pangea.  The research team says the southern coast of Angola, where they dug up the samples, arguably provides the most complete ...

Better than expected life expectancy in two disadvantaged areas in England is probably due to population change according to local residents and professionals. In the UK, people from the most disadvantaged areas can expect to die nine years earlier compared with people from the least disadvantaged areas while people in the north of England have lower life expectancy, higher infant mortality and worse health and wellbeing compared with national averages. The study, funded by the NIHR School for Public Health Research, was a collaboration between Lancaster University, ...

An international collaborative research team, including scientists from UQ’s Queensland Brain Institute (QBI), has discovered a novel mechanism underlying memory involving rapid changes in a specific DNA structure.   The team found that G-quadraplex DNA (G4-DNA) accumulates in neurons and dynamically controls the activation and repression of genes underlying long-term memory formation.   In addition, using advanced CRISPR-based gene editing technology, the team revealed the causal mechanism underlying the regulation ...

The study is published in Applied and Environmental Microbiology, a journal of the American Society for Microbiology. Ralstonia solanacearum species complex (RSSC) is a phytopathogenic bacterial group that causes bacterial wilt in ...

Social media. The climate crisis. Political polarization. The tumult of a pandemic and online learning. Teens today are dealing with unprecedented stressors, and over the past decade their mental health has been in sustained decline. Levels of anxiety and depression rose after the onset of the COVID-19 pandemic. Compounding the problem is a shortage of mental health providers — for every 100,000 children in the U.S., there are only 14 child and adolescent psychiatrists. In response to this crisis, University of Washington researchers studied whether virtual reality might help reduce stress ...

Scientists are harnessing cells to make new types of materials that can grow, repair themselves and even respond to their environment. These solid “engineered living materials” are made by embedding cells in an inanimate matrix that’s formed in a desired shape. Now, researchers report in ACS Central Science that they have 3D printed a bioink containing plant cells that were then genetically modified, producing programmable materials. Applications could someday include biomanufacturing and sustainable construction. Recently, researchers have been developing engineered living materials, primarily relying on bacterial ...

Weekly targets, annual resolutions, five-year plans—all of them so troublingly elusive. With best intentions, most of us fail to stick with the goals we set. Next time, consider pursuing them with a friend. New field research by Assistant Professor Rachel Gershon, published in Management Science, suggests that pursuing our goals with friends may make them more attainable. Gershon, along with Cynthia Cryder of Washington University and Katy Milkman of the University of Pennsylvania, ...

For ages now, plants have been the primary source of nutrition for animals and mankind. Additionally, plants are used for the extraction of various medicinal and therapeutic compounds. However, their indiscriminate use, along with the rising demand for food, underscores the need for novel plant breeding practices. Advances in plant biotechnology can address the problems associated with food scarcity in the future by enabling the production of genetically modified (GM) plants with higher productivity and resilience to the changing climate.  Naturally, plants can regenerate an entire new plant from a single ‘totipotent’ cell (a cell that ...

SPOKANE, Wash. – Despite ChatGPT’s reported ability to pass medical exams, new research indicates it would be unwise to rely on it for some health assessments, such as whether a patient with chest pain needs to be hospitalized.   In a study involving thousands of simulated cases of patients with chest pain, ChatGPT provided inconsistent conclusions, returning different heart risk assessment levels for the exact same patient data. The generative AI system also failed to match the traditional ...

PULLMAN, Wash. -- A new computer model uses a better artificial intelligence process to measure snow and water availability more accurately across vast distances in the West, information that could someday be used to better predict water availability for farmers and others. Publishing in the Proceedings of the AAAI Conference on Artificial Intelligence, the interdisciplinary group of Washington State University researchers predict water availability from areas in the West where snow amounts aren’t being physically measured. Comparing ...

A simple blood test could allow doctors to determine whether a person may be at higher risk for stroke or cognitive decline during their lifetime, according to a new UCLA Health study.  The study, published in the journal Stroke, found that measuring concentrations of a network of inflammatory molecules in the blood could allow doctors to calculate a risk score for susceptibility for cerebral small vessel disease – a common cause of stroke and a contributor to cognitive decline found especially among the elderly.   Currently, the only way to determine a person’s risk for cerebral vascular diseases has been ...

WASHINGTON, DC – May 1, 2024 – Three-quarters of Americans feel mental health conditions are identified and treated much worse than physical health issues within the U.S. healthcare system, even as more than 80% perceive a dramatic rise in prevalence of mental health issues in the last five years, according to a new survey from West Health and Gallup released at the start of Mental Health Awareness Month and Older Americans Month. Nearly identical percentages believe mental health is handled either “much” (38%) or “somewhat” worse (37%) than physical health ailments, while 15% say they are dealt with “about the same.” ...

Research Highlights: When adults became angry after remembering past experiences, the function of cells lining the blood vessels was negatively impaired, which may restrict blood flow. Previous research has found that this may increase the risk of heart disease and stroke. In this study, episodes of anxiety and sadness did not trigger the same change in functioning of the blood vessel lining. Embargoed until 4 a.m. CT/5 a.m. ET Wed., May 1, 2024 DALLAS, May 1, 2024 — A brief episode of anger triggered by remembering past experiences may negatively impact the blood vessels’ ability to relax, which is essential ...
