Bits and pieces from the internet: species edition

There is a bird inside this pistol.  Seriously! And it sings. Seriously wonderful things from the past. 

Why do we call it the 'human race' and not the 'human species'?  Personally I think it is because people didn't want to be thought of as on the same level as other species, such as monkeys, flowers, and sheep. Humans are supposed to be bigger, better, smarter and of higher value than other species in the world.  But we really are just a species... Wikipedia is solving this by redirection human race and human species to just 'human'.

A nice little interactive guide to endangered species of different parts of North America. (New York Times)

And don't you wonder what kind of living species might be found on the exoplanet Gliese 581d?  In our lifetime, do you think we will be able to know if there is life on other planets?  And if there is life, then there are probably different species.

Setting a curved record straight

If you have heard, like me, that there now are more people alive than ever have been alive before on Earth, you have heard a myth that seems very resistant and impossible to kill off.  Apparently somebody in the 1970s uttered this false fact, and it has made the rounds many times now in articles and books.

The truth, as calculated by the Population Reference Bureau, is that "about 5.8 percent of all people ever born are alive today."  (That is today = year 2002). Read their article, it is very interesting how they calculated it, taking birthrates and death rates, world population sizes, average age of death, etc. In total, they estimate that 106 billion people have lived on Earth until now.

Imagine all those millions and billions of people!  I think it is strange we don't run into old archeological bones more often than we do.

Out of Africa, again

Amazing news out of East Africa... a new 4.4 million year old hominid species (Ardipithecus) have just been described after 15 years of painstaking research. Old 'Lucy' (Australopithecus) was 'only' 3.3 million years old. Turns out that the common ancestor of chimps and humans, might have looked a lot more like a human than a chimp and not been adapted to tree-climbing, for example. Science is really great... I love it.

OK Snapshot: Human resources?

Albondigas!

We made a fantastically tasty dish on Saturday last week: Albondigas with ancho chili-tomato sauce. Albondigas are Mexican meatballs, and these had not only ground turkey in them but also lots of corn, onion, pinto beans, garlic, parsley, egg, and flour. You don't fry the meatballs, you boil them in a tasty sauce made from dried ancho chilies, tomatoes, and lots of spices. That way the sauce flavors the meatballs and vice versa. It was incredibly good! We made extra meatballs, so now we have enough for a second dinner. We served it with basmati rice with zucchini and sweet peppers and a few green beans. Perfect dinner, thanks PP! (link to recipe here)

PP and I have been reading Michael Pollan's long article in New York Times about the evolution of cooking during the last decades, starting with the TV dinners of the 1950s to the fast food and 'halv- and helfabrikat' (prepared foods) of today. There are some amazing facts in it, such as the AVERAGE time people use to clean up after dinner: 4 min. 13% of all dinner cooking is done by men (that is about 3 days a month). When you buy food in the store, 80% of the cost does not go to the farmer but to other companies. Michael Pollan argues that we no longer cook or really know how to cook, but we love to watch cooking shows on TV instead. Our family doesn't fit into these statistics, since we cook all the time, doesn't watch the shows, and try to buy as much as possible directly from farmers (moist and fresh!). I feel sad for the children and adults that live on fastfood burgers, frozen french fries, and instant noodle soup all the time. And here in the US, that seem to be most people, unfortunately. I don't agree with all Michael Pollan has to say, but it is worth reading. He misses the fact that local food and home cooking has had an enormous upswing recently and that many people are becoming more aware of the origin of their food and how to cook from scratch. I think blogs and politics have a lot do with this. Here is the article.

Some excerpts:
"Those corporations have been trying to persuade Americans to let them do the cooking since long before large numbers of women entered the work force. After World War II, the food industry labored mightily to sell American women on all the processed-food wonders it had invented to feed the troops: canned meals, freeze-dried foods, dehydrated potatoes, powdered orange juice and coffee, instant everything. As Laura Shapiro recounts in “Something From the Oven: Reinventing Dinner in 1950s America,” the food industry strived to “persuade millions of Americans to develop a lasting taste for meals that were a lot like field rations.” The same process of peacetime conversion that industrialized our farming, giving us synthetic fertilizers made from munitions and new pesticides developed from nerve gas, also industrialized our eating."

"Earlier this year, Richard Wrangham, a Harvard anthropologist, published a fascinating book called “Catching Fire,” in which he argues that it was the discovery of cooking by our early ancestors — not tool-making or language or meat-eating — that made us human. By providing our primate forebears with a more energy-dense and easy-to-digest diet, cooked food altered the course of human evolution, allowing our brains to grow bigger (brains are notorious energy guzzlers) and our guts to shrink."

I am reading the Catching Fire book right now, book review will follow. Now, go and crack some eggs in a frying pan and feel like a hominid.

If a moose eats asparagus...

... does the pee smell funny?

It does in humans, but only some people can smell it. There is evidence supporting that both the odor of asparagus urine and the ability to smell it are genetically controlled. I know I am one of those that can smell it. Isn't science great sometimes!? Giving us answers to both important and unimportant questions.

Stupid (or Intelligent) Design?



Just watch this and keep the intelligent design (creationism) debate in mind. Hilarious!

The Aliens Are Here!


Most of the time when you think about aliens your brain screams 'War of the Worlds! AAAAA!', but people who actually believe in extra terrestrials (ET's, UFO's, whatever the heck you want to call them) their brain gets exited and says 'Quantum jump in humanity! Yay!' or 'Non-polluting energy source! Yay!'.
Over 70% of all amercians believe that there is a government cover-up.......and they would be right. That's right, I said it. No I am not insane. Yes, I'm quite sure. The government wants to leave the public in the dark when it comes to the fact that there is really faster-than-light moving, soundless, massive objects that are flying in earth's atmosphere. Take a look at
http://www.theblackvault.com/ and you will know what I mean. It contains thousands of down loadable reports of 'Unauthorized flying in a restricted area' where, coincidentally, that object is going twice the speed of sound and is defying gravity.
But why? I mean, why us, out of probable billions of other life-forms? Two words: Nuclear Weapons. Ever since we discovered that by using decaying plutonium and uranium we would be able to create the most power full weapons in the world, the Aliens have screamed 'Oh my god! The kids have the matches!' In short, they are trying to keep us from destroying ourselves. But why not just land in Washington DC with thousands of antimatter laser cannons equipped to ships, and demand the cease of nuclear weapons? 1: It could cause intergalactic war. 2: They don't want to directly approach us for fear that either us or their fate might match that of the fabled do-do bird.
So, in total, anyone who denies the fact that Aliens have visited our planet (Whether you are a FBI agent or a common civilian), you will miss out. ALOT.
