Study suggests biological clock is key to reducing heart damage from radiation therapy
A new study suggests that the biological clock is involved in heart toxicity from radiation therapy and could be harnessed as part of a preventive strategy. Findings show that after receiving radiation to the heart, mice with disrupted biological clocks had significantly worse heart function than controls. They also demonstrated that Bmal1--a protein that drives 24-hour rhythms in the expression of many genes--plays an important role in protecting the heart from radiation-related damage. (2020-01-13)

Dinosaur skull turns paleontology assumptions on their head
A team of researchers at the University of Alberta has unearthed a well-preserved Styracosaurus skull -- and its facial imperfections have implications for how paleontologists identify new species of dinosaurs. Nicknamed Hannah, the dinosaur was a Styracosaurus -- a horned dinosaur over five metres in length with a fan of long horns. UAlberta paleontologists have learned much from those horns -- because they aren't symmetrical. (2019-11-25)

Separate polarization and brightness channels give crabs the edge over predators
Fiddler crabs see the polarization of light and this gives them the edge when it comes to spotting potentials threats, such as a rival crab or a predator. Now researchers at the University of Bristol have begun to unravel how this information is processed within the crab's brain. The study, published in Science Advances today, has discovered that when detecting approaching objects, fiddler crabs separate polarization and brightness information. (2019-08-21)
