Toxins force construction of 'roads to nowhere'
Toxins released by a type of bacteria that cause diarrheal disease hijack cell processes and force important proteins to assemble into "roads to nowhere," redirecting the proteins away from other jobs that are key to proper cell function, a new study has found.
Rapid fluctuations in oxygen levels coincided with Earth's first mass extinction
Rapid changes in marine oxygen levels may have played a significant role in driving Earth's first mass extinction, according to a new study led by Florida State University researchers.
Artificial neural networks learn better when they spend time not learning at all
Depending on age, humans need 7 to 13 hours of sleep per 24 hours. During this time, a lot happens: Heart rate, breathing and metabolism ebb and flow; hormone levels adjust; the body relaxes. Not so much in the brain.
The tilt in our stars: The shape of the Milky Way's halo of stars is realized
A new study has revealed the true shape of the diffuse cloud of stars surrounding the disk of our galaxy. For decades, astronomers have thought that this cloud of stars—called the stellar halo—was largely spherical, like a beach ball. Now a new model based on modern observations shows the stellar halo is oblong and tilted, much like a football that has just been kicked.
Study takes one small step towards human hibernation for long space flights
Bob McDonald's blog: A new study has given researchers one more reason to think about putting long-duration astronauts in cold storage. It may help protect them against dangerous cosmic...
