Sex is 'nothing but trouble', geneticist says
(Phys.org) —Sex determining genes in marsupials have shed some light on how the Y chromosome, which determines the male sex in humans, will quickly degenerate and eventually disappear, according to a world-renowned evolutionary ...
Novel way plants pass traits to next generation found: Inheritance behavior in corn breaks accepted rules of genetics
New research explains how certain traits can pass down from one generation to the next – at least in plants – without following the accepted rules of genetics.
Researchers identify genetic sequence that helps to coordinate synthesis of DNA-packaging proteins
Every time a cell divides it makes a carbon copy of crucial ingredients, including the histone proteins that are responsible for spooling yards of DNA into tight little coils. When these spool-like proteins ...
Whole genome sequencing of wild rice reveals the mechanisms underlying oryza genome evolution
In a collaborative study published online today in Nature Communications, researchers from Institute of Genetics and Developmental Biology, Chinese Academy of Sciences, BGI-Shenzhen, and University of Arizona have comple ...
Sri Lankan snake study reveals new species, rich biodiversity in island country
Alex Pyron's expertise is in family trees. Who is related to whom, who begat whom, how did they get where they are now. But not for humans: reptiles.
Home toxic home
Most organisms would die in the volcanic sulfur pools of Yellowstone and Mount Etna. Robust simple algae call it home, and their secrets to survival could advance human medicine and bioremediation.
Disease knowledge may advance faster with CRISPR gene probing tool
Scientists at UC San Francisco have found a more precise way to turn off genes, a finding that will speed research discoveries and biotech advances and may eventually prove useful in reprogramming cells to regenerate organs ...
How to thrive in battery acid and among toxic metals
In the movie Alien, the title character is an extraterrestrial creature that can survive brutal heat and resist the effects of toxins.
Dual systems key to keeping chromosomes intact
USC scientists have discovered how two different structural apparatuses collaborate to protect repetitive DNA when it is at its most vulnerable – while it is being unzipped for replication.
Epigenetics unveils how plants may adapt to environments throughout the world
Scientists at the Salk Institute for Biological Studies have identified patterns of epigenomic diversity that not only allow plants to adapt to various environments, but could also benefit crop production ...
How yeast responds to change: Development of new protocol provides key to measuring complete set of yeast protein levels
A procedure that allows accurate measurement of the levels of over 99% of the proteins generated by different strains of fission yeast could open the way for new laboratory applications of the species. Researchers ...
DNA's twisted communication: Genome organization key element for control of gene expression
During embryo development, genes are dynamically, and very precisely, switched on and off to confer different properties to different cells and build a well-proportioned and healthy animal. Fgf8 is one of the key genes in ...
Understanding termite digestion could help biofuels, insect control
A termite's own biology with help from microorganisms called protists, are keys to the insect's digestion of woody material, according to a Purdue University scientist.
Evaluating evolutionary rates could shed light into functions of uncharacterized genes
Genes that have roles in the same biological pathways change their rate of evolution in parallel, a finding that could be used to discover their functions, said a researcher at the University of Pittsburgh School of Medicine ...
