Researchers developed 'Library on a Slide' technique to compare bacterial genomes, allowing for efficient identification of genes associated with biological processes. The method involves printing genomic DNA at high density onto a glass slide and uses fluorescently labelled probes to detect target genes.
A new form of the MeCP2 protein has been discovered, which may be more important in causing Rett Syndrome. The protein is found to be more abundant in the brain and its function must be understood to relate it to the disease symptoms.
Research suggests that bone-marrow-derived stem cells do not differentiate into new heart muscle cells when injected into damaged hearts. Instead, they mature into traditional blood lineage cells. This challenges the idea of using stem cell therapy to repair damaged hearts and raises questions about alternative approaches.
A study found that adults with a lack of parental support during childhood are more likely to experience depressive symptoms and chronic health conditions in adulthood. Early life parental support shapes people's sense of personal control, self-esteem, and family relationships, which affects adult health.
A Cincinnati Children's Hospital study found a deficiency in lipoxins, key regulators of inflammation, in children with cystic fibrosis. This discovery provides impetus for developing novel therapeutics to decrease lung inflammation.
Researchers refute vibration theory by finding shape of odor molecules crucial for distinct smells. The study's results support the prevailing 'shape theory', which suggests that chemical shape is the primary factor in determining a substance's scent.
Researchers found that blood-forming stem cells lodge in damaged hearts but retain their blood-forming fate, contradicting earlier findings. The study suggests that these cells may not be able to transform into muscle cells, but could still offer some potential for treating heart attack patients
