Your coffee may be guilty of sexual discrimination
How do you take your coffee? Espresso, drip, instant, or brewed from a regular old coffee machine? Well, a recent study published in Open Heart suggests that gender and brewing method can alter your coffee’s effect on cholesterol levels.

Besides caffeine, coffee beans have naturally occurring chemicals such as diterpenes, cafestol, and kahweol that raise cholesterol levels in the blood. And then there are the various brewing methods, which are going to release different amounts of chemicals from the beans. According to Consumer Reports, an ounce of espresso has 63 mg of caffeine and an ounce of regular coffee has 12-16 mg. That’s a bit deceiving, though, since no one ever drinks an ounce of regular coffee, so figure 96-128 mg of caffeine for an 8-ounce cup. That’s enough to make anyone’s heart race.
Data from 21,083 participants in the seventh survey of the Tromsø Study who were aged 40 and older showed that women drank a mean of 3.8 cups per day while men drank 4.9 cups. Drinking six or more cups of plunger-brewed coffee was associated with increased cholesterol in both genders, but drinking three to five cups of espresso was significantly associated with high cholesterol in men only. Having six or more cups of filtered coffee daily raised cholesterol in women, but instant coffee increased cholesterol levels in both genders, regardless of how many cups they drank.
People all over the planet drink coffee, some of us like our lives depend on it. Since “coffee is the most frequently consumed central stimulant worldwide,” the investigators said, “even small health effects can have considerable health consequences.”
We’ll drink to that.
Have you ever dreamed of having a clone?
When will science grace us with the ability to clone ourselves? It sounds like a dream come true. Our clones can do the stuff that we don’t want to do, like sit in on that 3-hour meeting or do our grocery shopping – really just all the boring stuff we don’t want to do.

In 1996, when a sheep named Dolly became the first mammal cloned successfully, people thought it was the start of an amazing cloning era, but, alas, we haven’t made it to cloning humans yet, as LiveScience discovered when it took a look at the subject.
The idea of cloning was quite exciting for science, as people looked forward to eradicating genetic diseases and birth defects. Research done in 1999, however, countered those hopes by suggesting that cloning might increase birth defects.
So why do you think we haven’t advanced to truly cloning humans? Ethics? Time and effort? Technological barriers? “Human cloning is a particularly dramatic action, and was one of the topics that helped launch American bioethics,” Hank Greely, professor of law and genetics at Stanford (Calif.) University, told LiveScience.
What if the clones turned evil and were bent on destroying the world?
We might imagine a clone of ourselves being completely identical to us in our thoughts, actions, and physical looks. However, that’s not necessarily true; a clone would be its own person even if it looks exactly like you.
So what do the professionals think? Is it worth giving human cloning a shot? Are there benefits? Mr. Greely said that “there are none that we should be willing to consider.”
The dream of having a clone to help your son with his math homework may have gone down the drain, but maybe it’s best not to open doors that could lead to drastic changes in our world.
