Going Under: What we don’t know about anesthetics

anesthesiaaaaaaaaaa

Are anesthetics as safe as we think they are?

The majority of people reading this sentence will, at some point in their lives, undergo a medical treatment that requires general anesthesia. Doctors will inject them with a drug, or have them breathe it in. For several hours, they will be unconscious. And almost all of them will wake up happy and healthy.

We know that the general anesthetics we use today are safe. But we know that because they’ve proven themselves to be safe, not because we understand the mechanisms behind how they work. The truth is, at that level, anesthetics are a big, fat question mark. And that leaves room for a lot of unknowns. What if, in the long term, our anesthetics aren’t as safe for everyone as we think they are?

Self-Inflating bike tires promise a future free of hand pumps

The PumpTire consists of an inner tube, the tire itself, and a special uni-directional air valve that screws into the stem of the inner tube. When the pump is active, it uses the tire’s rolling motion to draw in air from the atmosphere, through the one-way valve and into a lumen that runs along the outer edge of the tire. As the tire rolls, it squishes the lumen flat, forcing air into the main tube and when the weight of the tire is removed, the lumen re-inflates before it’s rolled over again. The system automatically shuts the valve when the desired pressure is reached. The doesn’t require any special modifications or rims…

Unplanned pregnancies increase among low-income women

The unplanned pregnancy rate among women with incomes below the federal poverty line jumped by 50 percent between 1994 and 2006.

Nearly half of all pregnancies in the United States are unplanned and they are increasingly concentrated among low-income women, according to a new study.

Scientists discovered the “Missing Link” of beer brewing

Beech galls in Patagonia inhabited by Saccharomyces eubayanus, the species
researchers think combined with domesticated yeast to create a lager-producing hybrid.

Mystery solved! Scientists have discovered the “missing link” in beer brewing. Ladies and gents, take a good look at the orange-colored galls on the beech tree to your left: they were found to harbor the specific strain of yeast that makes lager beer possible.

How did lager beer come to be? After pondering the question for decades, scientists have found that an elusive species of yeast isolated in the forests of Argentina was key to the invention of the crisp-tasting German beer 600 years ago.

It took a five-year search around the world before a scientific team discovered, identified and named the organism, a species of wild yeast called Saccharomyces eubayanus that lives on beech trees…

Researchers identify food price tipping point linked to rioting

Rising food costs are a key reason behind rioting.

There’s no doubt that rising food prices in a specific area can lead to rioting. We have plenty of current and historic examples of that. But some interesting new research highlighted in Technology Review shows that once average global food prices cross a certain threshold a tipping point is reached after which “almost anything can trigger a riot, like a lighted match in a dry forest.”

Check out this graph which plots the UN Food Price Index against the dates of riots around the world…
