Researchers at Johns Hopkins University found that caffeine enhances long-term memory in humans by improving pattern separation. The study used a double-blind trial where participants received either a placebo or a 200-milligram caffeine tablet, and showed that more members of the caffeine group correctly identified new images as simil...
Researchers discovered a genetic signature that implicates key immune system mechanism in driving acute lymphoblastic leukemia, the most common form of childhood cancer. The study found that genomic rearrangement and deletions of DNA segments drive cancer progression.
Scientists have identified a mutated gene causing papillary craniopharyngiomas, a type of benign but devastating brain tumor. A targeted therapy approach using BRAF inhibitors may improve treatment outcomes, with plans for clinical trials underway.
Researchers found that variations in non-coding DNA sequences influence insulin-producing cell behavior in people with type 2 diabetes. Genome sequences controlling gene activity were identified, and genetic variants associated with diabetes risk were also linked to these clusters.
A new study demonstrates that ultrasound directed to a specific region of the human brain can enhance sensory perception. The technique showed significant improvements in distinguishing pins at closer distances and detecting small frequency differences.
Researchers develop 'Swiss-Army-Knife' molecule to capture RNA from individual cells in their natural tissue environment. This non-invasive method allows for the analysis of how cell-to-cell chemical connections influence gene expression and protein production.
High levels of molecular chlorine have been detected in the Arctic atmosphere, with concentrations peaking at 400 parts per trillion. The discovery highlights the potential for molecular chlorine to influence atmospheric chemistry and has implications for mercury cycling and ozone formation.
A research team, including Anthony Wynshaw-Boris and Shinya Yamanaka, successfully used induced pluripotent stem cell reprogramming to correct a defective ring chromosome with a normal one. This approach has potential to treat birth defects, mental disabilities, and growth limitations caused by chromosomal abnormalities.
A new MRI method using CEST technology measures creatine levels in the heart, providing higher resolution than traditional methods and potentially spotting heart problems earlier. This technique could lead to improved clinical decision-making and earlier detection of heart disorders.
Researchers at UNC School of Medicine and The Scripps Research Institute found a way to modulate specific pathways in opioid receptors, allowing for more precise targeting of brain diseases. This breakthrough could lead to better treatment options for chronic pain, Parkinson's disease, and depression with fewer side effects.
Researchers found that inhibiting STAT1 chain formation can block detrimental type-II interferon responses while preserving anti-viral protection, providing a new target for improving current treatments.
A new study found that the public has a strong negative view of climate engineering, with approaches like carbon capture and cloud brightening being better received. The results suggest that even well-regarded techniques still have a net negative perception.
Researchers discovered how sodium controls opioid receptors, a major class of brain cell receptors. The findings suggest new therapeutic approaches to treat pain and mood disorders. Sodium's effect on receptor activity is crucial for developing better opioid-receptor-targeting drugs.
A recent study identified a population of stem-like T memory cells where HIV persists despite treatment. These cells have the ability to regenerate new HIV-infected cells, fueling the virus's persistence in the human body. The findings suggest that targeting these cells could lead to novel interventions for future treatment.
A multi-institutional team has discovered a gene mutation associated with several cancers also drives a rare brain tumor called papillary craniopharyngioma. The BRAF mutation was found in 94% of tested papillary tumors, suggesting it could be targeted by existing therapies.
