Powering the Cell: Mitochondria

acampos says...

The idea behind this animation is to help students think and learn about the process of Oxidative Phosphorylation. That is why the video doesn’t have any explanation. We, in the classroom (General biology, biochemistry, microbiology and others), study cellular respiration and watch the video. Unfortunately, many students will search the internet to get the “correct explanation” rather that study and think as an attempt to get an A in the assignment. So, explanations like this do not really help the educational system not only because they are not precise (many mistakes and misinterpretations can be found) but also because it encourages students to cheat in their assignments. Wouldn’t be better to ask people to study rather than tell them what they are watching?

I get that the view is great, but...

Zen Delivers 9 Minutes of Stupidity about Tiny Hydrogen

We Know What a Healthy Diet Is. Now Can We Stop Arguing?

draak13 says...

Buttle is absolutely right; we don't know. Nutritional research continues as we learn more about about the incredibly complex biochemistry in our bodies. However, the narrator conveys this same idea a relatively roundabout way. We don't know what particular diet works best (he names vegan, paleo, and mediterranean diets specifically), but he claims that all of them will work well. We perhaps don't specifically know *why* they work, but there is compelling population level data to show that they do. We will eventually be able to unearth why they work, and then likely improve upon the diets further.

RedSky said:

Sounds like the same fad he's talking about. My recollection is cholestrol was recommended to be avoided (and I believe still is) for certain at-risk individuals however this was simplified to cholestrol = bad. Similar to the war against fat in food which led to it being replaced by added sugar / other carbohydrates which are in many ways worse in how they interfere with insulin.

TONS of things cure cancer. All day, every day. Doctors have no clue what cancer is. All they can do is cut, burn, or poison and cross their fingers.

No, you'd be remiss if you opined blatant misinformation.

While there is a possibility that cannabinoids can inhibit tumour growth, there is nothing even close to a solid evidence base to show that "cannabis cures cancer".

Science teacher got surprising results from McDonald's diet.

Trancecoach says...

@JiggaJonson

You may not have said that people lack self-control, but the article you posted indicated as much; that when it comes to food portions, people have difficulty curbing their appetites, and it's simply not true -- and it's seems like a facile excuse for not taking responsibility for oneself.

No one I know who actually wants to lose weight "eats less and exercises" (and I would add "eat healthfully" to that, as well). In fact, I don't know anyone who eats healthfully and exercises regularly and appropriately who is "overweight." (If you know anyone, feel free to put them in touch with me.)

I don't want to get all technical here, but obviously someone who has moldy intestines, "leaky gut," fatty liver, and the resulting blood sugar imbalances may have a difficult time losing weight. And, by no means do I think eating McDonald's is a good idea for any health-conscious person, but individuals need to take some responsibility for educating themselves about their own health. This isn't McDonalds' responsibility.

And yeah, the low fat craze was a bad idea (as I frequently pointed out to many in the 90's), but that's what you get when you trust certain "authorities" to tell you what to do and how to live (especially when it comes from the government and its cronies at the AMA).

If you eat healthfully, your body will tell you when to eat and when to stop. Only a messed up metabolism encourages overeating. For example, the insulin-adrenailne roller-coaster will, of course, have an effect on a person's capacities for immediate self-control. This is why people who binge tend to do so on sweets, wheat, and other no-so-great "foods." Do you know anyone who binges on broccoli? I do not.

So I agree that you need knowledge of what to eat, and this is something that often varies from person to person as we all have different biochemistries, but there are common elements to what more likely agrees with most everyone's health.

(Disclaimer: I am not giving medical advice here, as I have not been licensed by the medical "authorities" to misinform you, but in case you want to know more about the reasons for obesity, I encourage you to check this out for more information: http://www.majidali.com/the1.htm)

Going to the Doctor in America

Bruti79 says...

Neuroscience and biochemistry yes. =)

You may not like it, or find it romantic, but it's something we can see and observe.

What evidence do you have to present?

As for science as a religion? Nah, it doesn't work like that. Science is a series of conclusions based on observations (very watered down term.) If things happen that change our observations, we change our conclusions. When is the last time something religious or spiritual changed how they think. It happens a lot in science. In a counter point, it took the vatican about 400 years to apologize to Galileo. =)

I'm not saying it can't happen. I'm saying there is no evidence to support what you're saying. Because there are processes in the brain that we can see and observe and form opinion off of.

If you have a way or process that can show some fact/proof/observations off of spirituality, I'd love to see them. It's the same thing with ghost hunters, in the history of the world and people, the answer to anything has never been ghosts. =)

Integrating Psychedelics into Our Culture

bmacs27 says...

I'm pretty sure dosages measured in milligrams will suffice. Pounds seem a bit excessive. Also, it's easier to be taken seriously if you seem slightly less enthusiastic about drugs. They're fun and all, but once you start talking about "real realities" it's tough not to laugh you off. If there are indeed "real realities" that we are unaware of, the necessary research is probably in physics, not neuroscience or biochemistry or whatever.

We already have some ideas about what happens in your brain during ego-loss that seem to be much less of a stretch than "real realities."

Horsehair Worm Coming out of a Praying Mantis - Ewwwwww

kceaton1 says...

Yeah...the day we get a virus, bacteria, or straight up parasitic organism that can tell our brains to do certain things--I'm quiting the human species (I might be overstating it, but I certainly will become very paranoid concerning certain conditions, if you understand me), assuming it looks like this is going to be able to be spread via a fairly hardy species of: younameit. Zombies are one thing, but seriously I REALLY, REALLY, do not want these type of attacks to EVER reach us. Could you even imagine?

On the other side of things, I wonder if that is considered as the best dump evAr.(?) Second, it seems like it just a GREAT species as it seemingly has atleast two worms from the onset of infection (although it looked to me as though there was atleast one more still to come). I mean can the Praying Mantis even survive this event? Is it now the Prayed Upon Mantis instead?

All of the fungi, insects, and other species that use mind or nuerochemicals on their prey and then FORCE their prey to do any sort of commands to do miscellaneous things (like this one, get to water the natural home for that creature). It's literally amazing and terrifying at the same time. My scientific side is extremely engrossed by this and I'm literally in wonder at the amazing biochemistry at play--needed to do this hijack of the mind and to literally reboot it with a new program that told a FOREIGN BODY, something with literally no connection to the predator, it took control and got that body to go to a body of water so that the "litter" could hatch in their primal environment--a TRUE wonder of evolution, even though it is used in such a terrible way, it may have huge things in store for us research wise.

I'm waiting for the day that one of these little bastards makes a little leap and crosses-over and affects humans. Could you even begin to imagine the panic? I imagine that whatever it is would be much like smallpox and shortly after a few infections it would be eliminated from the face of the planet.

Protein Synthesis: An Epic on the Cellular Level

Religion (and Mormonism) is a Con--Real Time with Bill Maher

shinyblurry says...

I have claimed that there are methods to synthesize information that do not require the interaction of a mind. I have provided an example of one such system.

You object, but without either asserting that the simulation is a mind, or that it does not synthesize information, but instead you make some vague assertion about how it's instead not an example.


A mind created and designed it, therefore a mind is involved, therefore it is an invalid example..

Abiogenesis is, like all real knowledge, unproven. None the less it is, at present, the only coherent explanation for what can be demonstrated to exist.

Abiogenesis is unproven because there is no evidence, it is just metaphysics. It's your faith that it is true. It is not the only coherent explanation, it is just the explanation that you have to believe because you have ruled out an intelligent designer apriori.

There is no ID hypothesis, Behe came the closest to actually trying, and any competent high school biology student could pick his little charade to pieces in a few hours with a half decent encyclopedia.

Here is the hypothesis

http://www.ideacenter.org/contentmgr/showdetails.php/id/1156

Here is a story about ID being published in a biology journal making predictions for cancer research

http://www.discovery.org/a/2627

I am arguing not that there are no differences in the world, but that there is no concrete distinction between life and chemistry. You can assume there is, you can assert there is, but until you can demonstrate that there is I have nothing to disprove.

There is obviously a concrete difference since life doesn't come from non-life, and has never once been observed doing so. You have everything in the world to prove here. Everything in the Universe is made up of atoms, does that mean there is no difference between you and me? Is there no difference between a duck and a neutron star? You can't just say that because there are trivial similarities that they are the same thing.

And if you think like that, and you just believe we are all chemicals in motion, then you can't trust your own mind because if our mental processes are just chemical reactions, then there is no reason to believe anything is true. If our mental states have their origin in non-rational causes, rationality can't be trusted. You can't know if the rationality we have from evolutionary processes is discerning the truth of the world or not. Even Darwin realized this:

"With me the horrid doubt always arises whether the convictions of man's mind, which has been developed from the mind of the lower animals, are of any value or at all trustworthy. Would any one trust in the convictions of a monkey's mind, if there are any convictions in such a mind?"

The bottom right hydroxyl group is the only difference between RNA and DNA, to suggest that molecules can't lose parts, is to argue that the universe is not as it observably is.

Since the step you clearly label (MAGIC) in the RNA-> DNA path is so obviously trivial, why should anybody believe that the other step you label (MAGIC) is any more complex

?
Well this is plainly false. RNA to DNA is far more probable than ROCKS to RNA. The reason it is labeled magic is because there is no proof. It doesn't mean that they are both equally likely. It is less likely by large orders of magnitude.

The magic is RNA self-replication:

http://www.lifesorigin.com/chap10/RNA-self-replication-3.php

And if you had bothered to do any real research, you would see that the leap from soup to these complex molecules is anything but trivial..here is a list of just of basic issues...

http://www.godandscience.org/evolution/chemlife.html

Some quotes for you:

Instead of revealing a multitude of transitional forms through which the evolution of the cell might have occurred, molecular biology has served only to emphasize the enormity of the gap. We now know not only of the existence of a break between the living and non-living world, but also that it represents the most dramatic and fundamental of all the discontinuities of nature. Between a living cell and the most highly ordered non-biological system, such as a crystal or a snowflake, there is a chasm as vast and absolute as it is possible to conceive....

Molecular biology has also shown that the basic design of the cell system is essentially the same in all living systems on earth from bacteria to mammals. In all organisms the roles of DNA, mRNA and protein are identical. The meaning of the genetic code is also virtually identical in all cells. The size, structure and component design of the protein synthetic machinery is practically the same in all cells.

In terms of the basic biochemical design, therefore no living system can be thought of as being primitive or ancestral with respect to any other system, nor is there the slightest empirical hint of an evolutionary sequence among all the incredibly diverse cells on earth. For those who hoped that molecular biology might bridge the gulf between chemistry and biochemistry, the revelation was profoundly disappointing."

Dr. Denton, Ph.D (Molecular Biology),
An evolutionist currently doing biological research in Sydney, Australia

Now we know that the cell itself is far more complex than we had imagined. It includes thousands of functioning enzymes, each one of them a complex machine in itself. Furthermore, each enzyme comes into being in response to a gene, a strand of DNA. The information content of the gene (it's complexity) must be as great as that of the enzyme it controls.

A medium protein might include about 300 amino acids. The DNA gene controlling this would have about 1,000 nucleotides in its chain, one consisting of a 1,000 links could exist in 41000 different forms. Using a little algebra (logarithms) we can see that 41000 = 10600. Ten multiplied by itself 600 times gives us the figure '1' followed by 600 zeros! This number is completely beyond our comprehension."

Frank Salisbury,
Evolutionary biologist

Perhaps an "effort", but not a method, or a hypothesis. ID makes no predictions, it simply tries to find arguments to prop up a baseless assumption, that is the opposite of science.

If any ID proponent, or any theologian for that matter, can demonstrate even one example of anything true that their ideology can reliably tell us that we don't already know I will admit that it has predictive power, and that it could qualify as a hypothesis, and then eventually a theory. I'm betting you can't find one.

Sam Harris and Richard Dawkins: Morality and Science

L0cky says...

>> ^BicycleRepairMan:

The same could be said, as Harris puts it, the best advice to a country with high infant and mother mortality, is not to burn down schools designed to teach small girls to read.

This is clearly not "just" a real world descision anymore than our basic concepts of health at an individual level


If the goal is to engineer happiness for people, then you may spend time and effort on R&D in pharmaceuticals, biochemistry, neurology (Harris' background), etc. If the goal is to achieve happiness by changing the world around us, then you may spend time finding ways to improve education in poorer countries.

There's a stark difference in which one of these you invest in; whether you find one is more achievable than the other or not.

Granted, a "perfect happiness pill" may not ever be achievable; but we already know there is some degree of success with existing medication for a range of disorders such as anxiety and depression.

In health we look at the effects of medication (anti depressant helps this; anti-biotic helps that); but we also look at the effects of behaviour (eating too much does this, not exercising enough does that). The practice of one does not exclude the other; and I can concede that you could apply the same to morality.

I'm just not confident that there is as good of a correlation between moral decisions and happiness as there is between practice and health. Therefore you can't use happiness to measure the success of moral decisions in the same way that you can use health to measure the success of medical practices.

Irreducible complexity cut down to size

Actually, QS didn't call Behe pseudo-scientific... he called ID pseudo-scientific and I don't see how ID's validity can be seriously debated.

His critique of the blind watchmaker centered on the biochemistry of the eye, and it would be better if the video did as well.

Irreducible complexity cut down to size

bmacs27 says...

Okay, up front: I'm a vision scientist. I've also read Behe's arguments re: the irreducible complexity of vision. It's odd the way the introduction to this video characterizes his argument. Everything it says regarding the evolution of vision is correct. It is so accepted in fact that Behe even lays it out in his paper. He openly admits how easy it is to get from the eyespots on a mollusk to the human eye. He lays out all the steps, and explains how advantages are conferred at each stage, and thus how it is conceivable that such a thing could have evolved.

Behe, as a biochemist, was most concerned with how it is one gets to the simple eyespot in the first place. The biochemical machinery required for phototransduction is extraordinarily complicated. Many of the substances involved are in fact toxic to cells, and special mechanisms are needed to safely quarantine them. The process relies on extremely complicated proteins, for instance opsin barrels precisely tuned in order to create the appropriate energy barriers to 11-cis retinal isomerization. There are a multitude of other chemicals involved, which I won't go into, but frankly most are required for phototransduction as we know it.

Now, I agree, Behe is guilty of other logical problems, for instance poverty of imagination != QED, but he is well aware of the evolution of the gross anatomical aspects of the human eye. His critique of the blind watchmaker centered on the biochemistry of the eye, and it would be better if the video did as well. Instead, by writing him off as a "pseudoscientific" fraud, or similar ad hominem attacks, they are guilty of equivalent logical fallacies, and should be given equivalent respect. The guy is actually a scientist, with publications in journals such as Proceedings of the National Academy of Sciences, the Journal of Molecular Biology, and the Journal of Biophysiology, on topics like DNA and protein structure. Frankly, unless there is a CV somewhere I can see for these qualia-soup people, Behe has them trumped on credentials, so they might avoid the ad hominem, and critique the substance of the actual arguments put forth.

"In a recent article, “The Price of Biofuels“, David Rotman predicts that “significant technological breakthroughs” will be necessary to reach a goal in the United States of producing 35 billion gallons of renewable and alternative fuel by 2030. A professor of chemical engineering and biochemistry at Caltech, Fraces Arnold, says there are formidable barriers to the development of new biofuels:

“The bottom line is that you’re going to have to make fuel cheap. We can all make a little bit of something. But you have to make a lot of it, and you have got to make it cheaply. The problem is so huge that your technology has got to scale up.”

Three major challenges cited in converting biomass to biofuel include:
a.Optimizing yield, quality, and transportation of biomass
b.Improving the process of developing sugars from biomass
c.Creating highly efficient biological pathways to convert sugars into biofuel


Professor Gregory Stephanopoulos of MIT believes that a systems approach will likely be required to solve the multidimensional issues associated with creating an inexpensive biofuel generation process; an anticipated solution is a hybrid procedure that incorporates advances in both chemistry and biology.

Well, I guess they solved those problems pretty quick.

stupid education and science, making our health better by helping us be more compatible with our environment.

understanding how to identify a problem, seeing that there is a solution and then implementing the solution.... what is this country becoming? Comm-rape-ulist ChiRussia? BURY YER GUNS AND YER COMBUSTION ENGINES!! THEY TOOK YER FUEL!!! TUK ER!!! DEMOCRATS ARE RUINING EVERYTHING RABBLE RABBLE
