Researchers identified a key gene mutation causing Cornelia deLange syndrome, a childhood genetic disease. Mutations in the HDAC8 gene disrupt cellular recycling of cohesin, leading to impaired gene transcription and embryonic development.
Scientists at SLAC National Accelerator Laboratory have improved the Linac Coherent Light Source (LCLS) by using a diamond filter to create narrower X-ray wavelength bands, enabling sharper images of materials and molecules. This advancement promises to speed discoveries and add new scientific capabilities.
Researchers analyzed fungal genomes and transcriptomes to understand how lifestyle affects gene expression and host specificity. They discovered new functions for fungal infection organs, including sensing the presence of plants.
A Northwestern University study reveals that brain activity changes in olfactory regions after a week of blocked nostrils, compensating for the interruption of the sense of smell. The brain's response to odors returns to normal shortly after free breathing is restored.
Researchers discovered that cathepsins, involved in various diseases, may attack each other, reducing degradation of critical proteins like collagen. This phenomenon could explain the failure of current drugs to inhibit cathepsin activity.
Researchers have identified 10 new gene regions associated with type 2 diabetes, providing a fuller picture of the disease's genetic underpinnings. The study reveals patterns in genes involved in cell growth, insulin production, and fat cell communication.
Researchers from Columbia University successfully characterized van der Waals interactions in gold-molecule-gold junctions at the single-molecule level. This discovery opens up possibilities for designing and optimizing organic electronic devices with greater efficiency.
A study by Arizona State University reveals that megapolitan expansion could lead to local maximum summertime warming of nearly 4 degrees Celsius, surpassing the warming caused by increased greenhouse gases. The research found that incorporating 'cool roofs' into urban planning can alleviate summertime warming substantially.
Researchers have identified 38 new genetic regions linked to glucose and insulin levels, expanding the total number of associated genetic regions to 53. The study used a powerful technology to analyze DNA sequence variations for multiple traits at once.
A Yale research team has identified a single genetic switch that triggers loss of brain connections and contributes to depression. The study found that the transcription factor GATA1 represses genes necessary for synaptic connection formation, disrupting circuits involved in emotion and cognition.
