A study by University of Kansas researcher Argun Saatcioglu found that states with higher African-American populations and larger class sizes tend to teach more skills in early years, but reduce them later. This shift may be linked to a drop in state assessment scores and perpetuating inequality within disadvantaged communities.
A University of Utah-led study identifies a genetic variation in Tibetans that contributes to their adaptation to high altitudes. The EGLN1 gene change protects Tibetans from complications caused by low oxygen levels, allowing them to thrive in thin air.
Researchers at Columbia University Irving Medical Center have identified the immune cells responsible for destroying hair follicles in people with alopecia areata. A small number of patients showed complete hair regrowth after treatment with an FDA-approved drug, JAK inhibitors, which eliminated attacking T cells and restored hair growth.
A recent study has found that a rare genetic mutation in the DISC1 gene can corrupt neural connections, leading to disruptions in brain circuitry. The research, published in Nature, used induced pluripotent stem cells to model the effects of the mutation on human neurons.
A new study from Stanford Medicine explains how children's brains reorganize themselves as they learn math facts. The research found that the hippocampus plays a crucial role in building a schema for mathematical knowledge and provides a scaffold for learning and consolidating facts into long-term memory.
Researchers found that an inside-out vein graft filled with platelet-rich plasma (PRP) improved sciatic nerve function in rats compared to traditional autografting. The study showed increased myelination, axon diameter, and myelin sheath formation in PRP-filled vein grafts.
An Indiana University study found that temporary worker visas do not guarantee better jobs or wages for Mexican immigrants. In fact, these legal workers often earn less than undocumented immigrants, who can improve their situation by changing jobs or negotiating for better pay.
Researchers have discovered a definitive link between ancient worm-like creature Hallucigenia and modern velvet worms. A new study reveals that claws play a crucial role in the connection between these two groups, shedding light on the evolutionary tree of life.
People with schizophrenia struggle to convert desires into actions due to brain deficits affecting the caudate region. This impairment prevents them from making choices and behaving accordingly. The study's findings suggest that schizophrenics are 'stuck in neutral', wanting a normal life but unable to take necessary steps.
The OncoFinder algorithm reduces errors in transcriptome analysis by mapping gene expression onto signalling pathways, allowing for more effective evaluation and analysis. The method enables scientists to characterise functional states of transcriptomes more accurately, improving research and clinical applications.
A study by Susan R. Fisk found that women's anxiety in risky situations leads to worse task performance and lower grades than men, even when they have the same ability in non-risky settings.
A federal law aimed at reducing the use of 'club drugs' has failed, and instead put users at greater risk due to reduced access to safety measures like medical help and free water. The RAVE Act, enacted in 2003, targeted club owners but hindered their ability to provide necessary services.
Researchers have discovered strong evidence that epigenetic changes play a role in Alzheimer's disease, with specific DNA modifications linked to neuropathology. The study provides potential hope for understanding the mechanisms involved in dementia and highlights the importance of epigenetics research.
Researchers have shed new light on the epithelial-mesenchymal transition (EMT) process in cancer cells, using a microengineered device that acts as an obstacle course for cells. The study reveals that EMT upgrades cancer cells from an economy model to a fast sports car, allowing them to migrate aggressively to distant locations.
A team of scientists at Cold Spring Harbor Laboratory developed a new algorithm to analyze genome sequences and pinpoint insertion and deletion mutations involved in diseases. They successfully identified indels associated with autism and obsessive-compulsive disorder, shedding light on the genetic causes of these disorders.
A new approach measures the combined impact of climate and land use on biodiversity risk, highlighting areas vulnerable to losses in ecosystem function. The study suggests that regions like the Great Plains and Northeast US will face increased risks due to the combined effects of climate and land use change.
Researchers used ultrasound to monitor chitosan nerve conduits in rats, revealing unsatisfactory complications and degradation modes. This non-invasive technique enhances the assessment of nerve conduit outcomes, advancing peripheral nerve tissue engineering.
Scientists have successfully used a protection effect to enhance the stability of a promising quantum system, allowing for longer storage times. This breakthrough opens up new applications for hybrid quantum systems and could lead to ultrafast quantum computers.
Astronomers have accurately measured a rare black hole about 400 times the mass of our sun in a galaxy 12 million light years from Earth. The finding confirms the existence of intermediate-mass black holes, which were previously disputed due to lack of data.
A team of scientists analyzed a gorge on the Da'an Chi river in Taiwan over almost ten years, revealing a new mechanism that drives this process. Downstream sweep erosion is caused by a wide braided channel upstream, which gradually washes away bedrock surrounding the gorge.
A study by University of Washington sociologist Sarah Diefendorf found that young evangelical Christian men who pledged abstinence before marriage struggled with sexual temptation and confusion once married. The men reported feeling pressured to maintain control over sex and struggling to discuss it with their wives.
A recent study using stem cells found that a rare genetic variation, known as DISC1, reduces synapse growth in young brain cells, contributing to schizophrenia and depression. The researchers also discovered that the variation regulates the activity of over 100 genes related to synapses.
Researchers at Brigham and Women's Hospital discovered that early changes in brain DNA methylation are involved in Alzheimer's disease. The study found correlations between methylation levels and Alzheimer's disease in specific genes, suggesting a potential role for epigenomic modifications in disease susceptibility.
