Hypoxia Author: Marta Irigoyen is a postdoctoral researcher at CIC bioGUNE Despite the fact that c ancer treatments have greatly improved during recent years, chemoresistance remains a major problem in eradicating cancer cells. Drug resistance involves not only many cell intrinsic mechanisms but also extrinsic induced chemoprotection by the tumor microenvironment . In fact, this […]
Moons crashing together may have created Saturn’s rings Saturn’s iconic rings may be the result of a collision between two moons made of ice and rocks. Scientists simulated almost 200 collision scenarios and found that the impact of two moons roughly the size of Saturn’s current moons could disperse into icy rings, consistent with the […]
Layered rocks may be Earth’s oldest known fossils Researchers have found fossil evidence of what may be the first known life on Earth with the discovery of stromatolites, layered rocks formed by photosynthetic microbes, in Western Australia’s Dresser Formation that date back 3.48 billion years. Full Story: Live Science Sharks face rising extinction risk, other […]
Optimal workout timing may depend on gender Research on the relationship between exercise timing and gender indicates that women may see greater abdominal fat and blood pressure benefits with morning workouts, and evening exercise may help men burn more fat and better control their blood pressure. Working out in the evening also appeared to improve […]
Carbon generated by sea-dwelling microbes Microbes living deep in the ocean have been found to produce amorphous carbon, according to findings detailed in Science Advances. Scientists collected and cultured microbes over a number of years, noticing the production of black specks that turned out to be pure carbon. The Scientist Black hole’s plasma jets revealed […]
Pterosaur ancestry may have an answer Pterosaurs have been linked to a group of ancient small reptiles called lagerpetids, according to an examination of a variety of fossils from several regions. Lagerpetids, which date back between 237 million and 210 million years ago, share similar traits with pterosaurs, including inner ear shape, longer hand bones […]
Is this the first time there has been a fire of this magnitude? If there have been fires like this before, what damage was done to the mountain’s vegetation and how long did it take it to recover? Fires are quite common in the higher areas of Kilimanjaro at the end of the dry seasons […]
New Horizons finds light in the darkness of space The New Horizons space probe, which has moved beyond its exploration of Pluto, has found evidence that space itself has its own glow. When researchers removed visible light sources from images of the open universe sent back from the space probe, now about 4 billion miles […]
Glass bead chilled to its ground state Researchers have cooled a glass bead to close to absolute zero using a single laser with astonishing results: “Other cold-atom experiments can also create superpositions and quantum states, but what they can never do is create a superposition of all of the atoms in one place and all […]
Ladybugs are beautiful beetles and many present what is called an aposematic coloration, bright and striking colors that warn: do not eat me, I am dangerous. When they are disturbed, they defend themselves with legs and jaws, expel a poison and their brightly colored elytra with black dots are a warning to anyone who tries […]
