Adult rat myelin enhances axonal outgrowth from neural stem cells

Abstract Axon regeneration after spinal cord injury (SCI) is attenuated by growth inhibitory molecules associated with myelin. We report that rat myelin stimulated the growth of axons emerging from rat neural progenitor cells (NPCs) transplanted into sites of SCI in

Natural and sexual selection act on different axes of variation in avian plumage color

Abstract The bright colors of birds are often attributed to sexual selection on males, but in many species both sexes are colorful and it has been long debated whether sexual selection can also explain this variation. We show that most

Globally discordant Isocrinida (Crinoidea) migration confirms asynchronous Marine Mesozoic Revolution

Abstract The Marine Mesozoic Revolution (MMR, starting ~200 million years ago) changed the ecological structure of sea floor communities due to increased predation pressure. It was thought to have caused the migration of less mobile invertebrates, such as stalked isocrinid

The impact of blood type O on mortality of severe trauma patients: a retrospective observational study

Abstract Background Recent studies have implicated the differences in the ABO blood system as a potential risk for various diseases, including hemostatic disorders and hemorrhage. In this study, we evaluated the impact of the difference in the ABO blood type

NASA sees Super Typhoon Meranti’s extreme rainfall

Satellite data from NASA revealed that powerful storms in Super Typhoon Meranti were generating almost a foot or almost 300 millimeters of rainfall per hour. The Global Precipitation Measurement mission or GPM core satellite measured the heavy rainfall on one

Striatal dopamine regulates systemic glucose metabolism in humans and mice

A stimulating therapy for diabetes Blood glucose concentration is controlled by the hormone insulin. In patients with type 2 diabetes, insulin resistance leads to elevated blood glucose concentration and increased risk of developing cardiovascular disorders. The brain has been shown

Protons Contain 10 Times More Pressure Than a Neutron Star, According to First-Ever Measurement

In what was once thought to be an impossible task, for the first time physicists have put a figure on the pressure inside a proton – and it’s more impressive than we could have imagined. By shooting protons with high-energy
