This in turn stimulates the trigeminal nerve, which is a group of highly sensitive nerve fibers located behind the nose. Once the trigeminal nerve is triggered, it relays the information to the entire head. That is why you feel a brain freeze in your head and not in your mouth or nose,...
A subtype of H5N1 bird flu that has been found in cattle for the first time suggests that the virus jumped from birds to the animals twice. A headline-making study estimates that we have a spoon’s worth of microplastics in our brain. Streams of rock from a cosmic impact created the moo...

This is a fiery twist on acid-base experiments. Light a candle and talk about what fire needs in order to survive. Then, create an acid-base reaction and “pour” the carbon dioxide to extinguish the flame. The CO2 gas acts like a liquid, suffocating the fire. KiwiCo 25. Send secret ...
as a bubble, the line of pier etched clean, keen as a horizon knife, library ahead, ship at night behind. The bay to my right, as I said, slid dark at the confluence of all nights, the lights of low barracks and tall offices of the base ahead all aimed west skipped off bay each...
A small study presented in 2012 found that the sudden increase in blood flow and resulting increase in size of the anterior cerebral artery, a blood vessel located in the middle of the brain behind the eyes, may be responsible for brain freeze pain. The study found that when patients' brain...
Oddly enough, the conspiracy theory likely gets a bit of weight behind because of experiments in the 1950s and 1960s known as theDorset Biological Warfare Experiments. Similar experiments took place in the United States and in 1977 the US Senate Subcommittee on Health and Scientific Research led...

The concepts behind a basic confocal microscope and its use in SMD are schematically illustrated in Figure 3. Coherent light (typically from a laser and tuned to an optical transition of the molecule under investigation) behaves as a point light source and is focused into a sample chamber using...
