More polar ocean turbulence due to planetary warming

New research suggests that ocean turbulence and horizontal stirring will dramatically increase in the Arctic and Southern Oceans due to human-induced Global Warming. The study uses ultra-high-resolution simulations to investigate how mesoscale horizontal stirring (MHS) responds to warming, revealing a pronounced future intensification ...

What is a species? It could be difficult to reply if you work with aphids

Recent study published in Comparative Cytogenetics reveals that green peach aphids (Myzus persicae) can have unusual karyotypes due to chromosomal fragmentations and rearrangements. This challenges the conventional view of species stability, as observed karyotype variations often result in reduced fertility or sterility.

Advance in chromosomal evolution in sea cradles

Researchers analyzed chromosome changes in sea cradles, revealing a karyotype of 2n=24 chromosomes with biarmed elements. The study proposes that fusion among uniarmed elements drove this change in the Acanthochitonina suborder.

Are cancers newly evolved species?

Cancer researcher Peter Duesberg suggests that cancer is a form of speciation, where tumors are new species that operate independently and can grow without host control. This theory could lead to new insights into cancer growth and metastasis, as well as new approaches to therapy.
