A small number of bees die in the hive and some by preditors.
Why do the majority die away from the hive, remembering that the queen lays up to 1K eggs per day, these bees emerge, and bees only live 6 weeks during the summer. So we never find hundreds of bees dead in a hive, due to normal lifespan.
This question has nothing to do with disseases or preditors.

the body is about the size of a dime, maybe smaller; really long legs; somewhat hairy; light brown in color; doesn't spin a web. i've looked all over the internet, but can't find a spider like this anywhere. i live in southern arizona, and they are everywhere outside, but they only come out at night and they keep getting in the house.

Yesterday I had a colonoscopy done with biopsies. Ever since waking up, I have had pretty severe cramping in my abdomen, mostly on my left side. Is this normal? I mean, could my body still be reacting to all the laxatives I had to take? Any info is appreciated! Thanks!

I have a lot of roaches in my garage... It's impossible to get rid of them without using some sort of insect poison. And we are VERY clean.
I heard the Recluse feeds on cockies.

I have a sneaking suspicion of what these are, but I would be grateful if somebody a little more knowledgeable could take a look at these pictures and tell me what kind of spiders I have in my house. I've seen dozens of them. Thanks in advance for any information you can offer!
Billy.

This is for fun please do not reveal the way it works. Let others figure it out themselves.

This is a typical crafty way that psychics trick the public.

For example, O2 is broken into O, then the oxygen is combined with a group of O2 to make O3 (ozone). Can other molecules/compunds be broken apart by radiation? If so, how intense is that UV radiation? If not, how/is it possible to break up other compounds?
