Why haven't we been back to our moon?
Why haven't we been back to our moon?
We can send unmanned rovers there to study the moon in more detail, and for longer. Astronauts can only stay on the surface for around 3 hours due to the high level of radiation.
The moon landings were just used as propaganda.
Would not increase our knowledge of the moon in any way.
Provides no other advantage, scientific or otherwise.
Dangerous to the astronauts; they have to deal with large amounts of radiation; from the sun, cosmic rays, etc.
There are actually plans to send humans back to the moon and to set up a permanent base there, as well as on Mars.

Indeed. My next question would be; why bother with Mars when we have the Moon not so far away. Water?

The nucleotide sequence of one DNA strand of a DNA double helix is 5’-GGATTTTTGTCCACAATCA-3’.
What is the sequence of the complementary strand?

I'm a biologist so have a good understanding of bio and organic chem. not so much physics. Can you explain string theory?

The best thing about this theory is that it predicts the graviton, Scientists tried to remove this graviton, but that did not work.
That's the simplest I could put it

Do you think humans are halting our own evolution? If so, how? If not, why?

I think that the evolution of humans is slowing down (it will never completely stop), but that's because we don't really need to evolve. We have hospitals that can cure previously incurable diseases; the black death is still at large, but we don't hear about it since it can be cured with antibiotics.
So; evolution will never truly stop, but it may be slowing down. we cannot really say until thousands of years in the future (whatever we become)

Two intracellular molecules, A and B, are normally synthesized at a constant rate of 1000 molecules per second per cell. Each molecule of A survives an average of 100 seconds, while each molecule of B survives an average of 10 seconds.
A. How many molecules of A and B will a cell contain?
B. If the rates of synthesis of both A and B were suddenly increased 10-fold to 10,000 molecules per second-without any change in their average life*times-how many molecules of A and B would be present after 1 second?
C. Which molecule would be preferred for rapid signaling? Explain your answer.

I don't think so; evolution is a random process. if genetic modification became the norm, then maybe so. In the past 100 years, humans have grown 4 inches taller (I think that's the correct value), but this is due to diet not evolution. Anyway; why change something that is so perfect?
I think that the evolution of humans is slowing down (it will never completely stop), but that's because we don't really need to evolve. We have hospitals that can cure previously incurable diseases; the black death is still at large, but we don't hear about it since it can be cured with antibiotics.

Equally do you think stuff like hospitals are good thing for overall species fitness? Obviously morally they are a good thing but from an evolutionary stand point we like to allow deleterious mutations to survive and be passed on which isn't good for our overall fitness?
