The diversity of Asian genomes

January 26, 2020 – An effort to map thousends of genomes across Asia has certainly the potential to find novel gene variants affecting disease and responses to drugs, and to reveal the complex origins of Asian populations.

In a pilot study,

Hidden secrets in African genomes revealed by large scale sequencing

October 20, 2019 – Sequencing African genomes yields new data resource with broad applicability. By collaborating globally in a new, large-scale effort, researchers have made strong progress in sequencing genomes from regions and countries across Africa. These findings will enable more broadly representative and relevant studies ranging from basic through clinical genetics.

DNMT3B gene variant influences nicotine dependence

December 09, 2017 – Newest research has revealed that a DNMT3B gene variant influences nicotine dependence identified in people of European (Caucasian) descent and African-American decent as well.

Thus, a DNA variant, located in the DNMT3B gene and commonly found in people of European (Caucasian) and African-American descent,

Gene expression and ethnicity: Does it matter?

December 05, 2017 – We are entering the age of precision medicine, in which diagnosis and therapy decisions for each patient will be based on detailed genetic and molecular fingerprints. Unfortunately, much of the revolutionary work that underpins precision medicine has been conducted on populations of European (Caucasian) descent,

Cancer is not like cancer: Ethnic background matters

November 24, 2017 – New research indicates that one-size treatment for one form of blood cancer likely does not fit all, particularly when it comes to ethnic differences of patients.  Thus, African-American men are three times more likely to be diagnosed with multiple myeloma,

Ashkenazi Jewish Women: Little-known Gene Mutations May Boost Breast Cancer Risk

July 27, 2017 – Jewish women of Ashkenazi descent may be at risk for additional genetic mutations that increase their risk of breast cancer, according to a new study just published in JAMA Oncology. Researchers from University of Washington in Seattle found that around 4 percent of Ashkenazi Jewish women without well-known founder mutations in BRCA1 and BRCA2 genes have other mutations that may increase their risk for breast cancer.

  • Discovery of life in solid rock deep beneath sea may inspire new search for life on Mars April 2, 2020
    Newly discovered single-celled creatures living deep beneath the seafloor have provided clues about how to find life on Mars. These bacteria were discovered living in tiny cracks inside volcanic rocks after researchers perfected a new method cutting rocks into ultrathin slices to study under a microscope. Researchers estimate that the rock cracks are home to […]
  • Geneticists are bringing personal medicine closer to recently admixed individuals April 2, 2020
    A new study in Nature Communications proposes a method to extend polygenic scores, the estimate of genetic risk factors and a cornerstone of the personalized medicine revolution, to individuals with multiple ancestral origins. The study was led by Dr. Davide Marnetto from the Institute of Genomics of the University of Tartu, Estonia and coordinated by […]
  • Breast density, microcalcifications, and masses may be heritable traits April 2, 2020
    An analysis of a large Swedish cohort revealed that breast density, microcalcifications, and masses are heritable features, and that breast density and microcalcifications were positively associated with a genetic predisposition to breast cancer, according to a study published in Cancer Research, a journal of the American Association for Cancer Research.
  • Impacts of cover crop planting dates on soil properties after 4 years April 2, 2020
    Low biomass production limits cover crop effects on soils.
  • A next-generation sensor network for tracking small animals April 2, 2020
    A newly developed wireless biologging network (WBN) enables high-resolution tracking of small animals, according to a study published April 2 in the open-access journal PLOS Biology by Simon Ripperger of the Leibniz Institute for Evolution and Biodiversity Science, and colleagues.
