Maternal stress during pregnancy may shorten lifespans of male lizard offspring
Mother fence lizards that experience stress during pregnancy give birth to male offspring with shortened telomeres, or bits of non-coding DNA that cap the ends of chromosomes, according to a Penn State-led study. Shorter telomeres are associated with.....»»

Using DNA to move flavors between different varieties of tea
In plants, 5mC DNA methylation is an important and conserved epistatic mark involving genomic stability, gene transcriptional regulation, developmental regulation, abiotic stress response, metabolite synthesis, etc. However, the roles of 5mC DNA meth.....»»
The surprising behavior of male fruit flies under intense light conditions
A recent study published in Open Biology reports that exposure to intense light almost instantly provokes courtship behavior in male fruit flies (Drosophila). Surprisingly, the researchers observed both male-male and male-female courtship behavior un.....»»
Quercetin ameliorates oxidative stress-induced senescence in rat nucleus pulposus-derived mesenchymal stem cells: Study
Intervertebral disk degeneration (IDD) is a main contributor to low back pain. Oxidative stress, which is highly associated with the progression of IDD, increases senescence of nucleus pulposus-derived mesenchymal stem cells (NPMSCs) and weakens the.....»»
Cattle farming expansion and unchecked climate change would expose more than 1 billion cows to heat stress, study finds
More than 1 billion cows around the world will experience heat stress by the end of the century if carbon emissions are high and environmental protection is low, according to new research published today in Environmental Research Letters......»»
The "weird" male Y chromosome has finally been fully sequenced. Can we now understand how it works, how it evolved?
The Y chromosome is a never-ending source of fascination (particularly to men) because it bears genes that determine maleness and make sperm. It's also small and seriously weird; it carries few genes and is full of junk DNA that makes it horrendous t.....»»
Day-plus-night cooling strategies provide a cost-effective option against heat stress for dairy cows outdoors
Hot weather can have a big impact on dairy cattle health, well-being, and overall milk production for a herd. Dairy producers use a variety of effective cooling strategies to prevent heat stress including shade, fans, sprinklers, or a combination of.....»»
