7564I’ve read that when caterpillars are in their cocoons, they dissolve completely into goo; no original parts survive in the butterfly. How is the butterfly made from the goo? Is there an embryo that grows and uses the goo like a yolk sac? Or does the goo somehow arrange itself into new body parts?
126How sustainable is our landfill trash disposal model in the US? What's the latest in trash tech?
16396With all this fuss about net neutrality, exactly how much are we relying on America for our regular global use of the internet?
62If tooth decay is just caused by the bacteria feeding and producing acid, would a person that just used listerine have the same dental health as a person that brushed without flossing?
14Does boiling water in a low pressure atmosphere still kill pathogens?
14My doctor says that chemotherapy works by specifically targeting rapidly-dividing cells, which is how it works to fight cancer and also why it has the side effects that it does. But how does it “know” which cells are rapidly dividing? And how rapidly is “rapidly”?
10How mixable are different types of plastic? Like PET and HDPE?
17How are isotopes used in nuclear physics Experiments isolated?
843In 1996 NASA announced 'evidence of primitive life on early Mars'. In 2000, a second report supported the thesis. What happened next?
3What happened to the Global Cooling scare of the 1980's?
9How are the triple(or more) parachutes commonly seen on capsules returning from space kept apart?
3How are the needles for Atomic Force Microscopes made, and how can the tip be smaller than the atoms they are manipulating? What are their limitations?
5What makes a laser shine in a straight line?
82821Help us fight for net neutrality!
2How do scientists determine the weight of huge (extinct) animals?
2what's the difference between ZW and XY chromosomes, how did they evolve, and why are ZW organisms homogametic for males where XY organisms are heterogametic?
5What's the current state of AIDS? Is it still basically a death sentence, or is it manageable? What are the consequences of getting AIDS nowadays?
0If a pipe was run from space straight into the ocean would water run up it and flow into space?
2Can animals understand human body language like laughing or smiling?
3Lithium batteries are being developed to power cars in response to the decline in fossil fuels, but will lithium eventually run out as well?
1Question from my 4 year old sister, do other animals also get "Boogers"?
1Is there any short-term geothermal or atmospheric effect that is caused by the sun heating one "side" of the earth at a time?
18Could an electric vehicle stand a chance in a racing event?
22If there is an ocean below the ice surface of Europa, is the ice shell buoyant? Geologically supported? Or is it kept in place by the distribution of gravity?
1Is there a mathematical relationship between Moire patterns, Chladni plate vibration patterns, and the pattern formed by rings when making different cuts from wood?
2Would readers of character based languages (e.g Chinese) experience dyslexia differently since they don't use strings of letters?
4How to calculate eigenvalues in the Kirchhoff's thin plate model?
29Do all individual atoms in a solid emanate their own blackbody radiation?
10Is there anywhere other than Earth in the Solar system where you could see a total solar eclipse and/or total lunar eclipse equivalent?
6How did we get solid matter from light? How did Photons and Electrons create solid matter in the early ages of the universe when everything was insanely hot?
3Since the event at CERN that proved the existence of Higgs bosons/Higgs field, can we now see this event happen regularly now we know ‘where’ to look?
7Why does turning on an electric blender in the kitchen cause my HD antenna signal to go out in a different room?
5Can the human body survive breathing pure oxygen at lower pressures?
16When beryllium-16 decays and produces 2 neutrons simultaneously, what happens to that dineutron?
4How do we know the earth’s core is super hot and why is it so?
1How does the pressure of the vacuum of space affect the ISS?
11188From my kid: Can you put a marshmallow on a stick out into space and roast it with the sun?
3Given that cerebrospinal fluid flows around the structures of the brain, would messenger chemicals from synaptic activity in one area be passed to, and alter synaptic activity in other regions of the brain?
7How do we know what the tonsil does?
