    Does radiation from phones/PC's increase hair loss?

    A PC is designed to minimize radiation, which otherwise appears as electronic interference. A wireless router is much more powerful than a cellphone, assuming it isn't completely wireless but has a power cord. Battery operated devices tend to be low-power. Try comparing the temperature of each...

    Does radiation from phones/PC's increase hair loss?

    LOL The main cause of hair loss by far is genetic. But if you notice uneven bald patches appearing around one ear then... it probably still isn't your cell phone, unless you have mites living in it. Let's put it this way. If the radiation from your phone was strong enough to cause hair...

    A Beginner's Guide to Cell and Molecular Biology

    Looks okay to me. Make sure you get the actual book and not the study guide. However, you won't need to get the most up-to-date version, especially for an introductory undergraduate text.

    How to determine the time period.

    The "Long Now" clock is designed to work for 10k years, you could consult that to find the exact date for the next ten millenium, but I wonder if there is a natural clock precise enough to provide an exact date on geologic time scales. Not that anyone would actually need to now the exact date...

    How to determine the time period.

    Check the positions of the stars. Their proper motions are known and can be projected into the future with a great deal of reliability. The long hand of the galactic clock turns very slowly. If the stars have not moved then check the inclination of the Earth's axis, which varies in a...

    Could Oil from the Gulf of Mexico Be Causing Oily Residue on Windows in the UK?

    I think it is unlikely to be from the BP spill. The heat of the Gulf Stream would have evaporated off the more volatile components of the oil, leaving clumps of what would appear to be a lot like asphalt. The farther north it moves into the north Atlantic the less likely it is that something...

    The world without visual depth perception

    Chickens are one, but generally, any prey animal. Cows, deer, rabbits, etc. sacrifice binocular vision for improved field of view. It is harder to sneak up on them when they can see in all directions at once. Predators tend to have good overlap between the two eyes in order to better...
