I find the idea of common descent (that all organisms share a common ancestor) fairly convincing, and have no particular reason to doubt it.
The point here is that physics followed the data where it seemed to lead, even though some thought the model gave aid and comfort to religion.
We now had impressive evidence that low protein intake could markedly decrease enzyme activity and prevent dangerous carcinogen binding to DNA.
Despite some remaining puzzles, there's no reason to doubt that Darwin had this point right, that all creatures on earth are biological relatives
Irreducible complexity is a problem for Darwinian evolution. Whenever we see these complex functional systems we realise that they have to be designed.
The question of how the eye works - that is, what happens when a photon of light first impinges on the retina - simply could not be answered at that time.
You're in charge but don't touch the controls. Recounting what the two Russian cosmonauts tell her each time they leave the Mir space station for a spacewalk.
I first met the subject of X-ray diffraction of crystals in the pages of the book W. H. Bragg wrote for school children in 1925, Concerning the Nature of Things.
Everything in food works together to create health or disease. The more we think that a single chemical characterizes a whole food, the more we stray into idiocy.
I first met the subject of X-ray diffraction of crystals in the pages of the book W. H. Bragg wrote for school children in 1925, 'Concerning the Nature of Things.'
It was just using the liquid shampoo - the Russians have one very similar to the stuff we use on the Shuttle - you just wet your hair with it and then wipe it out.
I think that over the years, whether they want to admit it or not, people have to admit that the women astronauts have performed just as well as the men astronauts.
I learned easily and had time to follow my inclination for sports (light athletics and skiing) and chemistry, which I taught myself by reading all textbooks I could get.
I was married to Margaret Joan Howe in 1940. Although not a scientist herself she has contributed more to my work than anyone else by providing a peaceful and happy home.
A plant-based diet is more likely to produce good health and to reduce sharply the risk of heart problems, cancer, diabetes, osteoporosis, gallstones, and kidney disease.
When I got my PhD, it was a time when there were just no jobs for PhDs. Period. PhDs were getting the lowest paid technician jobs, if they were lucky, in any kind of science.
Thus far the chief purpose of our military establishment has been to win wars. From now on its chief purpose must be to avert them. It can have almost no other useful purpose.
Many people, including many important and well-respected scientists, just don't want there to be anything beyond nature. They don't want a supernatural being to affect nature.
However, it required some years before the scientific community in general accepted that flexibility and disorder are very relevant molecular properties also in other systems.
Furthermore, a pattern was beginning to emerge: nutrients from animal-based foods increased tumor development while nutrients from plant-based foods decreased tumor development.
Still I had a lurking question. Would it not be better if one could really 'see' whether molecules as complicated as the sterols, or strychnine were just as experiment suggested?
We can look high or we can look low in books or in journals, but the result is the same. The scientific literature has no answers to the question of the origin of the immune system.
Biology has progressed tremendously due to the model that Darwin put forth. But the black boxes Darwin accepted are now being opened, and our view of the world is again being shaken.
It’s never too late to start eating well. A good diet can reverse many of those conditions as well. In short: change the way you eat and you can transform your health for the better.
But sequence comparisons simply can't account for the development of complex biochemical systems any more than Darwin's comparison of simple and complex eyes told him how vision worked.
Nutrition is not a mathematical equation in which two plus two is four. The food we put in our mouths doesn't control our nutrition-not entirely. What our bodies do with that food does.
There is evidence that acupuncture influences the production of and distribution of a great many neurotransmitters and neuromodulators, and that this in turn alters the perception of pain.
A great advantage of X-ray analysis as a method of chemical structure analysis is its power to show some totally unexpected and surprising structure with, at the same time, complete certainty.
As the number of unexplained, irreducibly complex biological systems increases, our confidence that Darwin's criterion of failure has been met skyrockets toward the maximum that science allows.
The national debate on health-care reform wildly misses the mark, with Democrats and Republicans alike arguing about who's going to pay rather than about what would actually make people healthy.
The amphibious landing of U.S. Marines on September 1950 at Inchon, on the west coast of Korea, was one of the most audacious and spectacularly successful amphibious landings in all naval history.
Throughout history there have been many other examples, similar to that of Haeckel, Huxley and the cell, where a key piece of a particular scientific puzzle was beyond the understanding of the age.
I believe that we have been doing this not primarily to achieve riches or even honour, but rather because we were interested in the work, enjoyed doing it and felt very strongly that it was worthwhile.
In private many scientists admit that science has no explanation for the beginning of life... Darwin never imagined the exquisitely profound complexity that exists even at the most basic levels of life.
In short, it is about the multiple health benefits of consuming plant-based foods, and the largely unappreciated health dangers of consuming animal-based foods, including all types of meat, dairy and eggs.
Influenced by him, and probably even more so by my brother Theodore a year older than me, I soon became interested in biology and developed a respect for the importance of science and the scientific method.
Through art and science in their broadest senses it is possible to make a permanent contribution towards the improvement and enrichment of human life and it is these pursuits that we students are engaged in.
Basically, all my life I'd been told you can't do that because you're female. So I guess I just didn't pay any attention. I just went ahead and did what I could and then, when the stars aligned, I was ready.
One way to identify the optimal human diet, pretty obvious to all but fundamentalist reductionists, is to survey and compare populations as they already exist, and see what they eat and how healthy they are.
Influenced by him, and probably even more so by my brother Theodore (a year older than me), I soon became interested in biology and developed a respect for the importance of science and the scientific method.
After taking my B.A. degree in 1939 I remained at the University for a further year to take an advanced course in Biochemistry, and surprised myself and my teachers by obtaining a first class examination result.
In the 19th century the anatomy of the eye was known in great detail and the sophisticated mechanisms it employs to deliver an accurate picture of the outside world astounded everyone who was familiar with them.
Rejoice when other scientists do not believe what you know to be true. It will give you extra time to work on it in peace. When they start claiming that they have discovered it before you, look for a new project.
Since natural selection requires a function to select, an irreducibly complex biological system, if there is such a thing, would have to arise as an integrated unit for natural selection to have anything to act on.
It was a shock to people of the nineteenth century when they discovered, from observations science had made, that many features of the biological world could be ascribed to the elegant principle of natural selection.
In 1970, I had begun work on the basic pancreatic trypsin inhibitor which has later become the model compound for the development of protein NMR, molecular dynamics, and experimental folding studies in other laboratories.
And indeed this theme has been at the centre of all my research since 1943, both because of its intrinsic fascination and my conviction that a knowledge of sequences could contribute much to our understanding of living matter.
In Darwin's time all of biology was a black box: not only the cell, or the eye, or digestion, or immunity, but every biological structure and function because, ultimately, no one could explain how biological processes occurred.
By irreducibly complex I mean a single system composed of several well-matched, interacting parts that contribute to the basic function, wherein the removal of any one of the parts causes the system to effectively cease functioning.
A man from a primitive culture who sees an automobile might guess that it was powered by the wind or by an antelope hidden under the car, but when he opens up the hood and sees the engine he immediately realizes that it was designed.
