Slowly flapping its orange and black wings, a monarch butterfly sips liquid from a patch of mud. Its proboscis – the mouthpart that sucks up liquids – grazes the damp soil. For years, biologists knew that butterflies drew ...
Darwin's finches show enormous diversity in beak shape and size that varies with diet. The EU-funded Finch Evo-Devo project has used genomics plus – transcriptomics – to explain how 15 species of finch evolved from a single ...
Rice University nanoscientists have demonstrated a method for loading iron inside nanoparticles to create MRI contrast agents that outperform gadolinium chelates, the mainstay contrast agent that is facing increased scrutiny ...
It's certainly sad when to learn of a whale's death, given they are some of the ocean's most majestic mammals. While no doubt tragic, researchers on Dalhousie's Agricultural Campus are looking for the silver lining.
Cut off a salamander's tail and, in a few weeks, a near-perfect replacement grows. Do the same to a lizard and a new tail will regrow, but it won't be the same as the original. By comparing tail regeneration between the two ...
Tissue engineering is the future of medicine. The Polymer Materials for Tissue Engineering and Transplantology Laboratory of Peter the Great St. Petersburg Polytechnic University (SPbPU) has created unique polymeric materials ...
A trauma victim is wheeled into an emergency room, his thigh caked with blood-soaked bandages.
A newly published experimental protocol, involving University of Bristol scientists, could change the way fossilisation is studied.
Usually, facial trauma doesn't kill you, but it can cause significant disfigurement. Working as a maxillofacial surgeon in Glasgow in the early 2000s, Christine Goodall treated hundreds, if not thousands, of patients with ...
A key challenge in the embryonic development of complex life forms is the correct specification of cell positions so that organs and limbs grow in the right places. To understand how cells arrange themselves at the earliest ...
