Blood transfusion

The nurse who recovered from Ebola had received a blood transfusion from Dr. Kent Brantly, that first American missionary doctor who contracted the disease but survived.  So far, he has given about a gallon of his blood to others with the disease, and it seems to be helping.  The recipients and the donor must have compatible blood types, but the antibodies that successfully killed the virus in the survivor can be transferred into another person’s body.

I can’t resist the comparison to the blood of Christ.  He bore the disease of sin in His body and went so far as to die from it, though that particular virus was ours, not His.  But He rose from the dead.  Now His blood is our cure.  He gives us a blood transfusion:

And he took a cup, and when he had given thanks he gave it to them, saying, “Drink of it, all of you, for this is my blood of the covenant, which is poured out for many for the forgiveness of sins.” (Matthew 26:27-28) [Read more...]

The urination constant

I am a squeamish person, and I dislike talking about bodily functions.  But I stumbled upon a finding that is so interesting that I had to share it with you.  Did you know that virtually all animals, from a dog to an elephant–including human beings–take about the same amount of time to urinate?  That would be around 21 seconds.  See why after the jump.

The failure of reality to match up with computer models

The ice caps are supposed to be melting.  But the ice in Antarctica is at record levels.  And the ice at the North Pole, after declining for awhile, is back to normal levels.  So reports a British newspaper, the Register.  I’m struck, though, by a comment in the article that cites,  “This failure of reality to match up with climate modelling.”

That “reality” has somehow failed is rather humorous.  Isn’t computer modelling dependent on what data is programmed into the model?  And isn’t reality always going to be more complex than a model, with far more variables, many of which are unknown to the researcher?  [Read more...]

Both matter and anti-matter

Paradox of nature:  a sub-atomic particle has been discovered that acts like both matter and anti-matter. [Read more...]

Why do we sleep?

Virtually all living organisms sleep, or its equivalent.  But it has been a puzzle why.  Surely spending a big part of every day unconscious can’t have much survival value.  But scientists have now discovered that sleep is when our bodies repair themselves and when our brain is rejuvenated and, literally, cleansed.

Time has a fascinating article on the subject, linked and excerpted after the jump.  Type-A personalities who brag about how little they sleep so they can work more, party animals who stay up all night, commuters who stay up late and get up early, and college students in general would do well to read it.

The sound an atom makes

The ancients believed that the planets and stars were on crystalline spheres, whose turning created harmonics equivalent to our musical notes.  Hence, “the music of the spheres,” signifying the aesthetic order of the cosmos.   We don’t have that cosmology anymore, but we do have quantum physics.  Scientists have isolated the vibration and thus sound of a single atom.  It is the musical note, D.
