JEEZ! WHAT NEXT?

HANG UP THE OXYGEN HOSE?

The guy in the next cubicle grabs his chest and passes out.  Five long minutes later, the paramedics show up. On goes the oxygen mask. That should help, right?

Not exactly.

An article in the Cochrane Systematic Review lays it out.  387 patients. 14 deaths. The ones on oxygen? Three times as likely to croak.

Dr. Juan Cabello, says it’s amazing that emergency medical personnel have been routinely administering oxygen without proof that it works.

Amazing.

Much more data is needed before the profession changes a “gold standard”. But this information will get ’em thinking.

ScienceAintSoBadRating = 6 .

Startling and intriguing. Larger study needed.

EASY WITH THE UMBILICAL CORD CLAMP

According to Paul Sanberg (Center of Excellence for Aging and Brain Repair) blood keeps circulating in the umbilical cord for a little while after delivery. And that blood contains pluripotent stem cells.

Waiting at least an extra 30 seconds is good. Less intraventricular hemorrhage, sepsis,  and anemia. Less need for  for blood transfusions too.

So, OBVIOUSLY, we should wait, right?  Except those durn stem cells are mighty valuable. If you wait, you may lose them.

What’s the right thing to do?

Dunno.

How come everything’s so durn complicated?


MORE COFFEE, LESS BUZZZZ

Neuropsychopharmacology Journal: A study about coffee habituation . Do you get the same buzz, the same “wake up” effect, from a cup of coffe if you’re a heavy coffee drinker?

Wanna guess?

Of COURSE not! It’s like anything else. You build up tolerance. You even get a little hooked. Try going  “cold caffeine” sometime.

YOU GOTTA DIE TO BECOME OIL?

Coal, gas, and oil are hydrocarbons. They start out as living things.  Old reptiles, fish, leaves.

Even poop.

Which gets buried, compressed, and “cooked”.

That’s how it works.  Living things are the raw material. Geological processes take over from there.  That’s where most of our energy comes from.

That’s the official story, anyway.

But there may be a d-e-e-p-e-r explanation. Maybe way down in the earth’s mantle, nature manufactures hydrocarbons direct from the raw materials without requiring the intermediate steps that rely on dead life forms.

Would that mean there’s enough oil for a billion trillion years if we can figure out how to get down to it? Could we, mayhaps, have enough black stuff to TOTALLY cook the atmosphere?

It’s a theory.

We, obviously, know some GREAT ways to drill a couple of miles under the Gulf Of Mexico, but sampling the hydrocarbons 40, 50,  60 miles down’s an awful crimp for the budget of most research labs.

Researchers at Carnegie Institution’s Geophysical Laboratory described (Nature Geoscience) a more convenient way to figure out if there’s anything to this idea.

They had a diamond anvil cell lying around. And a laser. So they thought, “Well, wouldn’t it be fun to see what happens to methane at, say, 20 thousand times atmospheric pressure and at 2240 degrees Fahrenheit?” The same conditions that exist miles and miles down below your feet.

So they did.

The result? According to the article, ethane, propane, butane, hydrogen, and graphite. The process appears to be somewhat reversible too. Ethane to methane.

What’s this got to do with anything?

If deep sources of hydrocarbons migrate, gradually, to the surface of the earth, this may suggest that our nonrenewable  energy sources are likely to endure far longer.

That’s a good thing.

I guess.

ALCOHOL MAKES YOU SNEEZE

Well it does. Alcoholic drinks have histamine in them. That’s the stuff that gets your allergies going.  Anahad O’connor (New York Times) explains.

Twice as bad for women.

KIDS GET HIGH CHOLESTEROL?

Kids don’t have high cholesterol.

Well, hold on; they might (article in the Journal of Pediatrics). In fact, 1 in 3 kids have high levels of “bad” cholesterol.

Which is scary.

But what do you do? You gonna put a kid on cholesterol drugs?  Could be forever.

Would this give them healthier, better, longer lives?

Unless we do put kids on cholesterol reducing drugs, we’ll never know. Should kids be guinea pigs?

Should guinea pigs be guinea pigs?

ScienceAintsoBad‘ll be sure and let you know when they clear this up. For now, the American Academy of Pediatrics has some new guidelines which seem reasonable.
