YES, there is some truth behind the "1 billion heartbeats " claim. And when I say "some" I mean the creator of the comic didn't just make it up out of thin air. While it's not literally true that all animals get 1 billion heartbeats before they die, a relation between metabolic rate (which is related to heart rate) and life span has been observed. San José ...

If Homer talks about the dark-wine sea, it seems he also talks about the "blue eyebrows of Poseidon". You can read here about Homer's colorful descriptions that helped orators remember the verses of his poems. κυανό is known to be "blue" for ancient greeks and became "cyan" in english. In this book about Homer writing, κυανό entry represents "smalt, blue ...

The first claim is based on the research of Berlin and Kay "Basic Color Terms", which posits the hypothesis that languages evolve colour terms in the following order, and therefore that ancient languages did not possess separate terms for blue and green: Stage I: Dark-cool and light-warm Stage II: Red Stage III: Either green or yellow Stage IV: Both green ...

What do we mean by weaker, or by stronger? "Women really are stronger than men, according to study" Is the title of a BBC article which says A recent academic study has shown that under extreme conditions such as famines, epidemics and enslavement, women are able to survive for longer than men. Across modern populations, women outlive men in ...

Yes, that's Andre's hand. This image was part of the cover spread for a biographical article "To the Giant among us" in Sports Illustrated in 1981. The full cover spread includes regular-sized hands pouring a beer for comparison: The full article text for To The Giant Among Us is available on sports illustrated's vault.

No, this is not true. Not even for just India, as Indian cobra (Naja naja) has round pupils and subcaudal (tail) scales are divided. There is also no pit visible. It is venomous species of snake. This answer assumes, that author means venomous snakes instead of poisonous, as this is common mistake. Also, Wikipedia should have enough credibility for this ...

In short, we can assume that they do. There are two layers to this problem: whether crustaceans experience stimuli which could correspond to pain if those stimuli are effectively pain The second question is really hard to answer, and I would say, fundamentally philosophical. When does rubbing become scratching? So please bear in mind that I would find ...

"Smell" is a sense that is said to be more directly tied to emotional processing in the brain than other senses. But all interpretations of sensory information is subject to subjectivity. And smell is a sense that is easily and quickly dulled. Live in the stink and you get used to it, quickly. That makes it this a No. Smell is not objectively measurable as ...

No. Here are excerpts from an article written for Psychology Today The Rare Truth About "Tight" and "Loose" Women Post published by Michael Castleman M.A. on Sep 16, 2011 in All About Sex Many women complain that their vaginas are "too tight" or "too loose," and many men raise the issue about lovers. Notions of vaginal tightness and ...

This calculation is pretty much worst-case for the bicycle. It doesn't take into account that food production has actually stored CO2 from the atmosphere which is now just released back, while fuel was originally underground and its CO2 is added to the carbon cycle. Neither does it take into account mercury/other emissions, nor the wear-and-tear in cars and ...

We just need to look at sled dogs and do a little math. In 1986, Susan Butcher broke Rick Swenson’s record, set in 1981, by completing the 1049+ miles in 11 days. 1049/11 = 95 miles per day. This dwarfs a marathon, and marathon runners don't pull sleds. However, there are other races where we manage 71ish miles per day. This is for the Self-...

A “newton” is the international unit of force. A human adult’s maximum biting force ranges from 520-1,178 newtons depending on factors such as age and gender. It requires less than 200 newtons to bite through a raw carrot. This is well within the normal limits of the average person. Biting through a finger requires so much force that attempts often lead to ...

People have used chess as a model for studying stress responses and therefore have done a detailed metabolic analysis.

Yes, we are taller in the morning. From The transformation of spinal curvature into spinal deformity (2005): The effects of gravity on the upright human posture are powerful: Individuals are as much as 25 mm taller in the morning than in the evening (1)(2), as a result of compressive forces bearing down all day, And astronauts 'grow' by nearly ...

Here is one clue. Visit the IAAF's page of athletic records and compare the men's and women's, category by category. No woman on record has cracked the 10 second barrier for 100 meters. No woman on record has yet cracked the four minute mile. Male high school students regularly beat the female world record mile run time of just under 4:13. 4 American male ...

No. An "undigested protein stuck in our tissues and cells" implies that somehow untouched proteins (polymer chains made of amino acids linked together by peptide bonds) get through the process of digestion unscathed and are absorbed into the bloodstream. This doesn't happen, and someone would have to have some very serious problems with their entire ...

I remember learning the tongue map in school, but it's a myth. From The New York Times: In a study published in the journal Nature in 2006, a team of scientists reported that receptors for the basic tastes are found in distinct cells, and that these cells are not localized but spread throughout the tongue. That said, other studies suggest ...

I am not sure where these numbers come from and the answer depends on how you encode the genome data and if you define all the redundancy (unnecessary, repetitive data) as "information". First of all, the humane genome contains somewhere around 3.1 (men) to 3.2 (women) billion base pairs. Since the X chromosome is three times longer than the Y chromosome, ...

No From the Library of Congress: Dr. Block said that what is called the Valsalva maneuver, the creation of positive pressure in the chest when sneezing or coughing, is a complex and fairly violent physiological process. It may change the rhythm of the heart beat, he said, but it does not stop the heart. So where did the myth originate that your ...

tl;dr: Yes, there is a point at which recovery is not possible without significant medical intervention. Death by starvation is not simply a matter of running out of energy to sustain life, so cannot be treated simply by providing additional energy. Various bodily systems are damaged during the process of starvation and may remain impaired afterward. ...

No, this is not true. The Daphniidae only live for about 18.2 million heartbeats, which isn't even close to the (very loose) criteria of "within an order of magnitude". There are other species as well. All animals just do not have "around a billion" heartbeats. A good mammalian counter example is the North American black bear. Even when not hibernating ...

Short Answer As other have noted, it's not true under all conditions. For example, sled dogs can outrun people easily in cold weather (see DARPA studies). However, it sounds like the commentator was referring to the endurance running hypothesis, which says ancient humans were able to hunt down nearly any animal by outrunning it. The context is key, because ...

Data Estimated number of eukaryotic (human) cells in the human body: 1.0×1014 —Wolfram Alpha The haploid human genome (23 chromosomes) is estimated to be about 3.2 billion base pairs long. —Human Genome – Wikipedia The full DNA content of a cell is therefore 6.4 Gbp.

Yes. David Blaine was recognized by Guiness as setting the world record for static apnea with O₂ in 2008. He held that record for several months. Blaine set the record on the Oprah Winfrey Show; a video of the last few minutes can be found on the show's site. One can hold one's breath for much longer if one breathes pure oxygen prior to the apnea. The ...
