Worms are decomposers. Many survive by breaking down dead things — dead bacteria, dead plants, dead animals, dead anything. So, they must be accustomed to the stench of death. Not so, a new study suggests — not when the dead organism is another worm.Published in Current Biology, the study states that C. elegans roundworms react adversely to the smell of a deceased counterpart. Not only does this smell invoke a behavioral response of corpse avoidance, but it also invokes a physiological respo ...read more
So many unexplored secrets still lie at the outskirts of our solar system, where a potential candidate for a new dwarf planet lies. Although space beyond Neptune was thought to be mostly devoid of large objects, researchers are beginning to rethink this assumption after coming across an extraordinary trans-Neptunian object, called 2017 OF201. According to a recently published arXiv pre-print, 2017 OF201 could soon join the ranks of Pluto and other dwarf planets in the solar system. The behavior ...read more
The idea of using the body’s own organs as mini bioreactors to grow replacement tissue or even regenerate other organs might sound like something out of a science fiction movie, but it's already becoming reality in cutting-edge labs around the world.A collaboration between Wenzhou Medical University, Nanjing University, and the University of Macau has taken an unexpected turn in regenerative medicine by turning to the spleen, a lymphatic organ typically overshadowed by its more high-profile ne ...read more
Researchers have formally identified a group of elasmosaur fossils — some of the most famous in North America. The marine reptile, Traskasaura sandrae, a type of plesiosaur, has been added to a new and “very odd” genus which is unlike others known to science. T. sandrae had a 12-meter-long (about 40 foot) neck, and robust and sharp teeth that were likely used for crushing its prey. According to a new study, published in the Journal of Systematic Palaeontology, T. sandrae had an interestin ...read more
A cataclysmic asteroid collision may not sound like the starting place for life. But 66 million years ago, the Chicxulub impactor that wiped out the dinosaurs and much of the Cretaceous period’s fauna also kick-started a hydrothermal system that became a hotbed for life to recover in the local area. That’s the finding from a recent paper published in Nature Communications. Chicxulub Impact and Rapid RecoveryThe impact itself was truly a catastrophe, says Philippe Claeys, Chair of the Large ...read more
