In order to persist in insect societies, a parasitic fungus that turns ants into zombies manipulates its host to die outside of the colony, within the vicinity of foraging trails, a new study has found. This ensures a constant stream of susceptible hosts while also avoiding defense strategies employed by the colonies.
How many vowels does English have? Five, right? A, E, I, O, U. Oh, and sometimes Y. So, six? Actually, English has at least 14 different vowel sounds and, depending on the speaker and dialect, maybe more than 20.
In 12 exercises deploying only body weight, a chair and a wall, it fulfills the latest mandates for high-intensity effort, which essentially combines a long run and a visit to the weight room into about seven minutes of steady discomfort — all of it based on science.
While it is difficult at this stage to know whether these alterations to DNA are involved in the onset of disease or occur as a result of the disease, the findings are important because they may aid our understanding of the impact of environmental risk factors and lifestyle on Alzheimer’s.
Cornell now hosts a web site called Quantum Physics Made Relatively Simple, where you can watch three lectures presented by Bethe in 1999. They’re a little different from the usual lectures you encounter online. In these videos, Bethe is 93 years old, older than your average prof. And he presents the lectures not in a Cornell classroom, but at the Kendal of Ithaca retirement community, which gives them a certain charm.
A letter just released by Sociologists for Justice has been signed by more than 500 of them and counting (more than a hundred have added their names since the letter was posted with its original headline), and it's worth a read, in part because it contains some practical suggestions for how to prevent these sorts of tragedies from occurring in the future.
What do you get when you collect 27 years' worth of satellite pictures and turn them into GIFs? The scary realization that we can drastically change the face of the Earth in some years and not even realize it.
How did it get this far? This particular strain of Ebola -- called Ebola Zaire -- comes from Central Africa. How did it get to West Africa? Why did it start in Guinea, which has never seen the Ebola virus? And why is this happening now?
Forget the recent barrage of scientists saying that Shark Week programs are misleading, even deceitful. Shark Week isn't really about sharks — it's about ratings. And it's more evidence that the Discovery Channel, also home to Amish Mafia, among other programs of questionable authenticity, has not been interested in broadcasting scientific fact for quite some time.
In the 19th century, astronomers believed that solar systems formed in nebular clouds throughout the universe. But 20th century scientists rejected that idea, arguing that our solar system was an aberration. This mistake derailed the search for exoplanets, and extraterrestrials, for decades.
Carhart-Harris is the first person in the UK to have legally administered doses of lysergic acid diethylamide (LSD) to human volunteers since the Misuse of Drugs Act of 1971, and his presentation climaxes with a slide showing something no one else has seen before: an as-yet unpublished cross-sectional image of the brain of a volunteer who was in an fMRI scanner while tripping on acid.
