Discovery of new praying mantis species from the time of the dinosaurs
A research team has identified a new species of praying mantis thanks to imprints of its fossilized wings. It lived in Labrador, in the Canadian Subarctic around 100 million years ago, during the time of the dinosaurs, in the Late Cretaceous period. The researchers believe that the fossils of the new genus and species, Labradormantis guilbaulti, helps to establish evolutionary relationships between previously known species and advances the scientific understanding of the evolution of the most ‘primitive’ modern praying mantises.
Global warming means palms in surprising places – West Hawaii Today
A visit to Hawaii is the treat of a lifetime to millions of people a year, and many folks who come are friends or relatives of those of us who live here. One of the highlights for them is to…
Designer cytokine makes paralyzed mice walk again
Using gene therapy, a research team has succeeded in getting mice to walk again after a complete cross-sectional injury. The nerve cells produced the curative protein themselves.
Are partially protected areas the ‘red herrings’ of marine conservation?
Partially protected marine areas create confusion and don’t meet their broad conservation objectives, researchers have found.

How plants produce defensive toxins without harming themselves
Scientists describe the biosynthesis and exact mode of action of diterpene glycosides in wild tobacco. These antiherbivory compounds attack the cell membrane. To protect themselves from their own toxins, tobacco plants store them in a non-toxic form. Autotoxicity and the protection against it seem to play a greater role in the evolution of plant defenses than previously thought.
Evolution: Speciation in the presence of gene flow
Spatial isolation is known to promote speciation — but researchers have now shown that, at least in yeast, the opposite is also true. New ecological variants can also evolve within thoroughly mixed populations.
2020 tied with 2016 for Earth’s hottest year, as global warming overpowered La Nina – The Keene Sentinel

New imaging method reveals if antibiotics reach bacteria hiding in tissues
Researchers have developed a new imaging method to see where antibiotics have reached bacteria within tissues. The method could be used to help develop more effective antibiotic treatments, reducing the risk of antibiotic resistance.
