New research into pangolin genomics may aid in conservation efforts
A new paper in Molecular Biology and Evolution provides, for the first time, a comprehensive set of genomic resources for pangolins (sometimes known as scaly anteaters) that researchers believe will be integral for protecting these threatened mammals.....»»
How proteins roll the dice to determine bee sex
To date it has been unclear exactly how the sex of a bee is determined. A research team from Heinrich Heine University Düsseldorf (HHU) including biologists and chemists has now identified a key gene and the molecular mechanism linked with it. In th.....»»
Exploring stellar hydrogen burning via muons and nuclei
The muon is a subatomic particle that resembles an electron but is 200 times heavier. It interacts with nuclei through the weak force, one of the four fundamental forces in the universe. When a muon binds with a deuteron (composed of one proton and o.....»»
Molecular knots, left and right: How molecules form knots
Helical molecules, similarly to a corkscrew, have a spiral shape that can be either left- or right-turning. Such "chiral molecules" can collectively organize (assemble) into large left- or right-handed twisted structures. These exhibit special optica.....»»
