Antibiotics save us from all kinds of unfortunate ailments, from strep throat to ear infections. But the bacteria that cause these and other ailments are gaining an edge. Antibiotic resistant bacteria are on the rise around the world and spreading in people as well as the environment, making it harder to treat infectious diseases.
Antibiotic resistant bacteria grow in places that humans interact with, like our water systems. Urban wastewater treatment plants teem with antibiotic ...read more
People have long known that the canine sense of smell is a powerful tool. Dogs lend their super snouts to help find missing people, illegal drugs, and even screen for diseases like malaria and cancer. Now, scientists say that dogs can add a new talent to their sniffing repertoire: detecting seizures.
A small study has found that humans emit a distinct odor during epileptic seizures, and that some dogs can be trained to recognize the smell. In a new paper published in Scientific Reports th ...read more
NASA's Cassini mission to Saturn may have ended in 2017, but researchers are still analyzing the vast amount of data it sent back over its final spectacular months. Astronomers most recent findings, published Thursday, center on five of Saturn’s small ring moons: Pan, Daphnis, Atlas, Pandora and Epimetheus. During six close flybys near the end of its mission, Cassini uncovered new insights into how the moons formed, and what gives them their different colors.
And astronomer ...read more
Heart disease is the leading cause of death around the world. Many cardiovascular disorders damage blood vessels, the network of ducts the heart pumps blood through to send oxygen and nutrients to the rest of the body. But fixing damaged blood vessels often requires replacing them with blood vessels from other parts of the body or synthetic substitutes. Neither solution is great.
Now researchers report Wednesday in the journal Science Translational Medicine that they have engineered a ...read more
A new global study of ancient Martian riverbeds shows they are wider than Earth rivers on average, and once carried large volumes of water and runoff. They also flowed until surprisingly recently in Mars’ history, perhaps into the last billion years. This is a puzzle, given the Red Planet’s current desert environment, its thin atmosphere and dim sunlight. These features should have prevented vast water resources even early in the world’s history. Now scientists must p ...read more
