Amazing and intriguing questions and answers from the team behind the international phenomenon Why Don't Penguins' Feet Freeze?

The popular-science magazine behind the runaway international bestsellers Why Don't Penguins' Feet Freeze? and Does Anything Eat Wasps? takes on another irresistible batch of the strange, silly, and mind-boggling questions that plague curious minds the world over:
- Can pigeons sweat, can fish get thirsty, and can insects get fat?- Could a person commit the perfect murder by killing someone the day after receiving a full blood transfusion?- Is there a way to beat the odds of the lottery by using math?- How much mucus does a nose produce during the average cold?- If forced to eat parts of yourself to survive, which non-vital organs would be the most nutritious?
Culled from New Scientist's popular "The Last Word" column and edited by Mick O'Hare, the author of How to Fossilize Your Hamster, Do Polar Bears Get Lonely? is guaranteed to amuse and amaze as much as it informs.

(And if a polar bear appears to be lonely, it probably means there wasn't enough walrus for dinner.)

the rabbits evolving an immunity, but natural selection favored viruses that did not kill the host so rapidly, or even left it alive. This is an example of a virus increasing the time it takes for its host to die, not increasing the host’s longevity over that of an uninfected animal. A virus’s main aim is to replicate as many times as possible as quickly as possible. To do this it takes over the host cell’s DNA replication and protein synthesis capabilities and eventually breaks the cell apart

rolling portholes or hanging over a chaotically heaving taffrail, while gazing down at chaotically heaving water, doesn’t work at all, breeze or no breeze. Jon Richfield One reason that people who are nauseous feel worse if they move from a cold to a hot environment may be that exposure to heat induces greater expression of the enzyme heme oxygenase. This is a heat-shock protein that is produced throughout the human body. It breaks down hemoglobin, myoglobin, and cytochromes into iron,

couple of hundred yards above underlying earth or bedrock, except by filling ancient valleys or lakes. Such deep sands and spongy sandstone form important groundwater reservoirs. And yes, sand does form and reform constantly as water erosion, frost, and wind-driven particles flake grains off rocks. Conversely, deep moist layers of sand become cemented into sandstone, which in turn may go through the same cycle after millions of years. Far deeper sand occurs in submarine detritus fans, which

they can free-fall using a conventional parachute. We don’t yet have the technology to make the first two parachutes. And if anyone traveling this way made any mistakes they would become spectacular meteors.

His latest attempt in May 2008 failed when his helium balloon—intended to transport him into the

mostly colorless, phenolic compounds, causing them to polymerize and form pigmented tannins. Over time, these produce the brick-red color. Often tannin complexes grow as they react with other wine constituents, such as proteins, and many become too large to stay in solution and precipitate out, leading to the sediment you may find in aged wines. White wines start out in bottles with a greenish tinge (young wines in Portugal are called vinho verde) and end up with a browner hue. White wines are
