The New Guinea flatworm visits France – a menace

by Piter Boll in Earthling Nature

by Piter Kehoma Boll For as long as life exists, it spreads. Organisms move (even if only as gametes or spores) and conquer new environments if they fit. If it wasn’t so, life wouldn’t be found all over the world. … Continue reading →... Read more »

Journal Club: Telomere length: a new measure of chronic stress in wildlife?

by GrrlScientist in Maniraptora

SUMMARY: Two independent studies find a positive relationship between social environment and telomere length. The first study -- that nearly everyone has heard about -- is in children. The second study -- that few have heard about -- is in pet grey parrots. The second study raises the question: might telomere length be developed as a new way to measure chronic stress -- in animals? ... Read more »

Telomere length: a new measure of chronic stress in wildlife? | @GrrlScientist

by GrrlScientist in GrrlScientist

Telomeres, the DNA-protein caps that prevent chromosomal fraying, are positively affected by social stress, according to two independent studies that were just published within days of each other. One study -- which has received widespread media coverage -- found a positive relationship between social environment and telomere length in children, adding support to previous work in people. A second study -- which few have heard about -- found that accelerated telomere erosion is associated with so........ Read more »

Scientists Like Some Animals Better than Others (Hint: Bears)

by Elizabeth Preston in Inkfish

In the fight for attention from researchers, there are winners and there are civets. That’s what researchers found when they analyzed almost 16,500 published papers about animals from walruses to weasels. They saw clear trends in which animals are the most popular to study. And it matters because the most popular animals aren’t necessarily the […]The post Scientists Like Some Animals Better than Others (Hint: Bears) appeared first on Inkfish.... Read more »

Bioenergy From Forestry Is Not Sustainable Enough for EU

by dailyfusion in The Daily Fusion

The levels of forest residue bioenergy, considered to be sustainable from a forestry perspective, may provide considerable reductions in greenhouse gas emissions in European countries. Still, these reductions fall short of a 60 % threshold planned by the EU. This mismatch may have important climate policy implications.... Read more »
