When you dab hydrogen peroxide on a cut, that white, fizzling foam is actually a sign that that the solution is killing bacteria as well as healthy cells. Hydrogen peroxide (H2O2), a compound made up of two hydrogen atoms and two oxygen atoms, begins to breaks apart as soon as it conta...
In 1932, Canadian mathematician John Charles Fields called for the creation of an "International Medal for Outstanding Discoveries in Mathematics" that should be "in recognition of work already done" and "an encouragement for further achievement." According to Barany, early committees avoided rewarding...
The phenomenon is a bit like how the Rocky Mountains divide North America into east and west. On the one side are "terrestrial" planet, such as Earth and Mars. They are made up of fundamentally different types of materials than the more distant "jovians," such as Jupiter and Saturn. "T...
Herbivory has traditionally been seen as a powerful catalyst for the origin of new species—an often-cited example is the insects, with an estimated 1.5 million described species the most diverse group among the arthropods. Many new species of flowering plants appeared during the Cretaceous period,...
Normal cells have several ways to remove hydrogen peroxide, keeping it at very low levels so it does not cause damage. The new study shows that an enzyme called catalase is the central route for removing hydrogen peroxide generated by decomposing vitamin C. The researchers discovered that cells ...
Southern Indian Ocean and recently EgyptAir MS804 over the Mediterranean, the aviation industry should reconsider the safe recording of flight data and flight-deck voice communications (the so-called 'black boxes') on a cloud facility, remote from the aircraft where it is instantaneously accessible...
or exist in a shared state where the properties of two particles show whatEinsteincalled "spooky action at a distance", no matter what theirphysical separation. Because such things have been confirmed in experiments, researchers are confident the theory is right. But it would still be easier to...
The great Laurel-or-Yanny debate of 2018 was so fun because it shined a light on the often-illusory nature of auditory perception. What you hear may not be the same as what somebody else hears. Or, perhaps what you hear could change over time. What surel
