An international team reconstructed a 1,000-year timeline documenting human impact on the ecosystem surrounding Crawford Lake. The analysis of sedimentary ancient DNA samples revealed changes in plant, animal, and microbial communities over the centuries.
Researchers found that two subtypes of bacterial vaginosis increase the risk of developing chlamydia infections. The study analyzed cervicovaginal microbiomes before, during, and after infection with chlamydia, identifying a link between specific bacteria types and increased risk.
Researchers developed a new 'pan-pathogen' deep sequencing approach to capture multiple bacterial strains simultaneously. This method enables faster and more comprehensive tracking of antibiotic-resistant bacteria, potentially preventing and managing common hospital infections quicker.
Scientists at RIKEN Center for Brain Science find that somatic mutations in six genes lead to intracranial aneurysms, which can be blocked with a drug. The study establishes the first non-surgical animal model of intracranial aneurysm and provides a potential new treatment option.
CHOP researchers used deep sequencing to discover several previously undescribed genetic variants in vascular anomalies, capturing low-frequency mutations that were missed by conventional methods. The study found significant improvements in symptoms for over 63% of patients, enabling targeted therapies and improved quality of life.
Researchers at the Max Planck Institute found that specific start sites (TSSs) are linked to distinct end sites (TESs), shaping the RNA landscape unique to each tissue. Dominant promoters, which overrule conventional signals, drive this process and are conserved across species.
A new snake family, Micrelapidae, was identified through an international study led by Tel Aviv University researcher Prof. Shai Meiri. The family includes only three species, two in Africa and one in Israel, and diverged from the rest of the evolutionary tree about 50 million years ago.
A recent study published in Immunity reveals that human T-cell receptor genes exhibit unexpectedly high variability among individuals, with each person having a unique set of gene variants. The researchers identified 175 new gene variants originating from Neanderthals, which are present in up to 20% of modern humans in Europe and Asia.
Researchers found associations between cancer treatments and accumulated mutations in blood cells, a sign of accelerated aging called clonal hematopoiesis. This accumulation increases the risk of blood cancer and death in long-term childhood cancer survivors.
A new study found that the detection of resistant variants is only possible using population deep sequencing, suggesting treatment with antibiotics may contribute to their presence. The research highlights the potential for PDS to improve understanding of pathogens like Streptococcus pneumoniae and inform treatment strategies.
A new PCR test can quickly identify all SARS-CoV-2 variants in a positive patient sample, providing crucial information for public health professionals and policymakers. The assay has been shown to have high sensitivity and specificity, making it an valuable tool in monitoring emerging strains.
Researchers developed an advanced method to detect low-level somatic mutations in intractable epilepsy with 100% accuracy, surpassing conventional sequencing analysis which stands at 30%. The study used deep sequencing replicates of major focal epilepsy genes and identified mutations in approximately 5% of patients.
Tel Aviv University researchers developed miRNAkey software to analyze microRNA patterns in healthy and diseased tissues, improving understanding of human diseases at a genetic level. The software enables scientists to identify relevant microRNAs, determine their levels, and generate statistically valuable information.
