Research shows increased AMPAR activity in both motor and visual cortex during learning tasks, indicating a whole-brain approach to motor control. This challenges the long-held assumption that motor-based learning occurs solely in specific brain regions.
A study published in the American Society for Horticultural Science journal HortTechnology found that simply gazing at an indoor plant can reduce psychological stress in office workers. The researchers discovered that even passive involvement with plants, such as having a plant on their desk, contributed to significant anxiety reduction.
Researchers have identified the structure of a lethal toxin produced by C. difficile bacteria, paving the way for new drugs to neutralize it. The finding uses cryo electron microscopy and X-ray crystallography to map out delivery and binding components of the toxin.
Researchers studied over 9,500 veterans, finding that former enlisted personnel reported poorer outcomes on well-being compared to officers, while deployed veterans experienced poorer health. Many veterans struggled with chronic health conditions, anxiety, and depression, leading to eroding broader well-being over time.
Researchers have discovered a novel mechanism of ice growth in two dimensions, shedding light on the atomic structure of low-dimensional water. This finding may lead to the development of new materials for efficient ice removal, particularly for wind turbines and other applications.
A new study has established a framework for measuring protein glycosylation, a process critical to the development of safe and effective antibody-based drugs. By pooling data from various labs, researchers have created consensus estimates of glycan composition, shedding light on the variability in measurement techniques.
A US astronaut on the International Space Station developed a deep vein thrombosis, prompting UNC expert Stephan Moll to consult and develop a treatment plan. Moll advised on using Enoxaparin and Apixaban to effectively treat the blood clot, which was successfully managed over 90 days.
Researchers at Boston University School of Medicine have discovered the protein c-Cbl has the ability to degrade PD-1, a critical immune checkpoint that helps cancer cells evade the immune system. This finding may lead to new therapies targeting c-Cbl to treat certain types of cancer, including melanoma and non-small lung cancer.
Research in mice suggests that short chain fatty acid supplementation can improve stroke recovery, reducing motor impairment and increasing spine growth on dendrites. The gut-brain connection plays a crucial role in this process, with microglia activity linked to improved stroke outcome.
A study published in Current Biology found a link between dopamine, the brain's pleasure center, and the biological clock, which regulates daily rhythms. Mice fed high-calorie diets became obese due to disrupted feeding schedules, highlighting the importance of timing in eating and weight management.
Research by Lancaster University and the University of Oregon reveals that infertility disproportionately affects working-class people, those with disabilities, and others. The study calls for greater healthcare equity and inclusive reproductive health surveillance to address these disparities.
A new laser-based system has been developed to detect and measure the levels of all biomolecules, including proteins, sugars, fats, and their derivatives. This technique offers unparalleled sensitivity and can be used for all known classes of biomolecules, enabling the detection of precancerous and malignant cells in body fluids.
A new study assesses country and regional progress towards 17 UN Sustainable Development Goals (SDGs), revealing disparities between developed and developing regions. The study suggests that sustainability progress is dynamic and may involve tradeoffs, highlighting the need for a holistic approach to address these challenges.
Researchers from Oklahoma State University Center for Health Sciences studied two mid-sized, immature T. rex skeletons to understand the tyrant king's teenage years. The team found that the small T. rex were growing as fast as modern-day warm-blooded animals and underwent drastic changes as they matured.
Researchers from Washington University in St. Louis and Argonne National Laboratory have successfully reversed the flow of electrons in a purple photosynthetic bacteria, achieving a 90% yield on the B-branch side. This breakthrough discovery sheds light on the earliest light-driven events of photosynthesis and could aid in designing bi...
A new study refutes the idea that small Tyrannosaurus rex specimens represent a separate genus, instead revealing they were juvenile versions of their larger counterparts. The research found evidence of rapid growth in these young T. rexes, suggesting they likely played different roles in their ecosystems than adults.
A new noninvasive diagnostic method using circulating tumor DNA can detect colorectal cancer in at-risk patients with high accuracy. The technology, developed by Huiyan Luo et al., uses methylation markers to identify patients with a sensitivity and specificity of 87.5% and 89.9%, respectively.
New research reveals anti-abortionists using civil rights protections to lobby against early abortions. Pro-lifers compare fetuses to Black Americans and LGBTQIA people to strengthen their case, misrepresenting medical facts in the process.
A new study finds that tau protein is a more reliable predictor of brain atrophy in Alzheimer's patients than amyloid plaques. Tau PET imaging technology has the potential to accelerate clinical trials and improve individualized patient care.
Researchers found that intravenous BCG vaccination significantly increased protection against TB in rhesus macaques. The study showed that IV BCG elicited strong, sustained T cell responses in the lungs, leading to a high degree of protection against infection and disease.
A new study found that delivering the TB vaccine intravenously dramatically improves its potency, offering nearly full protection against TB in monkeys. The vaccine was highly effective when administered via injection into a vein, reducing bacterial burden by 100,000-fold and inflammation in lungs to near zero.
A new study has shown that a protein therapy called rhPDGF-AB can improve the quality of scar tissue after a heart attack, leading to the formation of new blood vessels and reduced rates of dangerous heart arrhythmia. The treatment has increased survival rates in animal models and holds promise for improving patient outcomes.
Researchers found that annual river ice cover will decline by about six days for every one degree Celsius increase in global temperatures, affecting communities and industries. The study also detected widespread declines in monthly river ice coverage, particularly in the Tibetan Plateau, eastern Europe, and Alaska.
