Montana bio station researchers discuss mine risks to salmon rivers

przez admin
Recently, a group of 23 science and policy experts from the U.S. and Canada published a review of mining risks to watersheds ranging from Montana to British Columbia and Alaska. The paper brought together experts in salmon ecology, watershed science, mining impacts and mining policy to integrate knowledge across research fields that often work independently from one another.

How placentas evolved in mammals

przez admin
The fossil record tells us about ancient life through the preserved remains of body parts like bones, teeth and turtle shells. But how to study the history of soft tissues and organs, which can decay quickly, leaving little evidence behind? In a new study, scientists use gene expression patterns, called transcriptomics, to investigate the ancient origins of one organ: the placenta, which is vital to pregnancy.

New method boosts the study of regulation of gene activity

przez admin
Researchers report the development of a chemical-based sequencing method to quantify different epigenetic markers simultaneously. Their method, called NT-seq, short for nitrite treatment followed by next-generation sequencing, is a sequencing method for detecting multiple types of DNA methylation genome-wide.

’Soft’ CRISPR may offer a new fix for genetic defects

przez admin
Scientists have developed a new CRISPR-based technology that could offer a safer approach to correcting genetic defects. The new 'soft’ CRISPR approach makes use of natural DNA repair machinery, providing a foundation for novel gene therapy strategies with the potential to cure a large spectrum of genetic diseases.
