The end of the “noble savage”

Archaeologists have discovered the site of a deadly massacre in which 27 people were killed by primitive weapons.  The researchers date the site at some 10,000 years ago and say the people were hunter-gatherers.  This upsets the theory that warfare and organized violence appeared only when early humans settled down into permanent settlements.

This also upsets the perhaps related theory of the “noble savage” of Jacques Rousseau, according to which primitive people in “the state of nature” live lives of peace and virtue, with violence and other evils coming only as a result of “civilization.”  Apparently, human beings have been fallen and sinful as far back as we can see.

Your brain has as much memory as the internet

New research into the brain’s synapses has found that the human brain has 10 times the memory capacity previously thought.  In computer terms, it comes to at least  a petabyte, the memory capacity of the world wide web.

Now use your internet-sized brain to think about that.  Didn’t the world wide web have to be, you know, designed and created?  Could the internet have come into existence purely through random processes?  Yes, the internet is an example of a system with millions of separate agents, sort of like the economy, but doesn’t it require pre-existing minds?  So what about the 7 billion minds existing on the earth today, each with the capacity of the entire internet?

Has climate change killed the aliens?

In this vast universe, say many scientists, surely intelligent life has evolved elsewhere.  So where is it?  A new theory is being put forward:  the aliens are all dead.  This is because, in the course of evolution, when intelligent life advances to the industrial level, it inevitably causes climate change that causes its species to become extinct.

Biomedical studies that aren’t reproducible

A key principle of the scientific method is that experiments must be reproducible.  That is, an experiment has scientific validity only if another person tries the same experiment and gets the same result.

It has been coming out that a big percentage–possibly a majority of psychological and social science experiments are not reproducible.  That is understandable, since human beings are active agents and so cannot be expected to be as predictable as inanimate objects.

But now scientists are discovering that a large percentage of biomedical studies are also non-reproducible! [Read more...]

Prosecute global warming skeptics?

A group of 20 scientists is urging the president to prosecute scientists and organizations  that question global warming. Now a Rasmussen survey has found that 27% of Democrats agree with that approach.  So do 11% of Republicans and 12% of Independents. [Read more...]

Let’s declare Pluto a planet again

Pluto lost its status as a planet in 2006, but the New Horizon space probe has found that it is no little frozen space rock, as had been assumed.  Rather, it is one of the most complex, varied, geologically-active, and mysterious entities in the Solar System.  It has water, glaciers, ice mountains, and blue skies.  It is even colorful.  I say let’s call it planet again!
