До 1972 года старением считалось накопленный объем поломок в организме. В 1972 году ученые открыли апоптоз -- запрограммированную смерть клетки. После этого считалось, что геном заставляет гибнуть клетки во благо организма, в котором он живет.
В 2002 году был открыт феноптоз -- запрограммированная смерть групп клеток (организма) и это изменило общее представление о старости. Геном убивает организм-хозяина, т.е. сам себя! Это происходит в целях общего эволюционного процесса, другими словами, ради более высшей цели, вид избавляется от индивидов.
Старость -- это постепенное и согласованное ослабление функций организма под управлением генома. Другими словами это ПРОГРАММА. А раз это программа, то ее можно...
Организм -- всего лишь машина, слепо выполняющая приказы генома. Как правило, эти приказы учитывают интересы организма, без которого геном гибнет. Однако некоторые из генетических программ нацелены прежде всего на ускорение эволюции или экспансию генома в биосфере. Такие программы и являются феноптозом -- котр-продуктивные для организма и продуктивные для эволюции. Именно из-за этих программ гибнут клетки и организм для ускорения эволюции, главной цели естественного отбора.
С другой стороны, человек в отличие от животных, обладает разумом и не заинтересован в своей биологической эволюции. Задача любой эволюции -- это максимально приспособить организм к среде. Современный человек не приспосабливается к среде, а приспосабливает среду под себя. Защиту своего генома он может обеспечить ограничением рождаемости, а не феноптозом (самоубийством).
Продукты SISEL -- это первые продукты, которые помогают человеку выйти из под гнета генома, чтобы стать HOMO SAPIENS LIBERATUS -- ЧЕЛОВЕКОМ РАЗУМНЫМ ОСВОБОЖДЕННЫМ.

In the Heat of the Night 03.09.2012 In the Heat of the Night
This video introduces the fascinating world of Hot Plants, flowers that generate heat (thermogenesis) to release scents and attract pollinators. We look at three thermogenic plant species, the monocots Philodendron bipinnatifidium and Colocasia esculenta and the eudicot, Nelumbo nucifera. Some plants such as Philodendron and Sacred lotus are also able to regulate their floral temperature, maintaining their flowers at up to 30 ?C above air temperatures over several days. Our research team is investigating how plants produce this heat and how they can regulate their temperature so precisely. We are also interested in why the plants produce heat. Is it to release particular scents to attract pollinators, to give a heat reward to the insects or does it also help the plants reproductive development?

OXPHOS - Oxidative Phosphorylation 03.09.2012 OXPHOS - Oxidative Phosphorylation
3Dme presents a look at OXPHOS - Oxidative Phosphorylation to help you visualise this complex process.

Through a fascinating process called oxidative phosphorylation, oxygen is used by the mitochondria to absorb electrons & help generate energy. This video uses beautiful, high definition 3D visualisation to take a look inside the human body to follow the path the oxygen molecules take from the in breath, osmosis through the arterial membrane, bound by haemoglobin in red blood cells, to reach the mitochondria. Once inside the mitochondria, the powerhouse of all cells, we demonstrate how oxygen is used to produce energy. This process includes the oxidation of macronutrients, electron carriers such as NADH, the electron transport chain & the cytochrome oxidase complex. Creative imagery has been used in this video to facilitate your understanding of the process of oxidative phosphorylation. We welcome your feedback & suggestions re: future topics you would like to see 3Dme produce for the upcoming App Video Catalogue.

Bacterial Flagellum - Evolution's Nightmare & Demise 03.09.2012 Bacterial Flagellum - Evolution's Nightmare & Demise
About the Bacterial Flagellum video and more:
More at http://www.detectingdesign.com
Detailed response to Nick Matzke's proposition on the bacterial flagellum:
http://www.idthink.net/biot/index.html
Another video (unrelated to the flagellum but very impressive):
http://aimediaserver.com/studiodaily/harvard/harvard.swf
-Evolutionist claim that all of life's features (example: the bacterial flagellum) can be explained by the purely material process described in their theory - accidental mutations sorted by natural selection. However, Intelligent Design (ID) theory makes the claim that certain features exist in the universe (including features of life) that are BEST explained by an intelligent cause (ie. a cause with a goal or purpose - ergo originating from a mind). With the scientific hypothesis of intelligent causation, and the objective explanatory filter developed by Dr William Dembski - http://www.uncommondescent.com - ID theory has quickly & firmly established itself as the "official" headache for the most ardent evolutionists today. Those that are informed know what is at stake, and that the explanatory power of the intelligent design theory is effectively guaranteed to supplant a purely materialist theory of evolution in time. This can be seen in how ID has reached a type of critical mass of acceptance - wherewith about a hundred classes are already taught in various universities (including the Ivy league). Classes whcih challenge purely materialistic thinking and more critically analyze the theory of evolution. The growth will continue as more objective & open minded scientists & students eager to explore better explanations continue to pursue better science.

Dr Michael Behe (author of "Darwins Black Box" & proponent of ID) popularized the term *irreducible complexity* to describe features in life which are complex and yet their function can not be reduced without destroying the primary function and usefulness of the system/function to the host organism. In the case seen in the video, the bacteruial flagellum has approximately 40 finely matched protein parts that must all be in place for the bacterial flagellum (w/ motor) to work. Furthermore, the assembly process of this motor is one of the key overlooked aspects of the problem of this systems development - ie. even the assembly program/process is arguably irreducibly complex. So, not only does a bacteria need to have the DNA coded for the correct proteins, the whole cell has to 'know' WHERE to put each protein part and WHEN to put it there. This is an astronomically improbable task to acheive through random fortuitous increases in instruction sequences (which to this day remains purely hypothetical - ie. imaginary) and parts specifications - consider the relative size of the cell surface area to the size of the bacterial flagellum and the chances each molecular part will assemble in the correct location & with the correct timing for assembly. So, the whole machine and the ORDER or sequence of system assembly is critical to success! If the whole universe were a fishbowl like earth's oceans - except fully teeming with bacteria - for 15 billion years, there would still be insufficient probablistic resources to accomplish the feat of builindg up such a comparable system even once. It's no wonder that ID theory is so satisfying to the many open minded scientist it has attracted.

Unfortunately, most evolutionist oppose this theory based strictly on materialistic beliefs. And this is a true detriment to real science. They stubbornly maintain their faith in natural selection - listen to Richard Dawkins - note especially the last words in the following video:
http://www.arn.org/docs/dawkins.mpg

[Excerpt - In exressing why natural selection is believed to find creative designs/solutions to all these kinds of intermediate problems]: "Natural selection is uhmmm..uhhh.. well, I suppose that is a sort of matter of faith on my part." - Richard Dawkins

If never before, you have now found that faith is a absolute neccessity and type of trade-secret of even the most outspoken of evolutionist. So, don't be their fool when they say evolution is a scientific fact. It's almost assured, in my opinion, that future generations will find it hard to believe that people ever accepted the theoy of evolution with the information we have at our disposal. Recent breakthroughs in accelerated protein folding algorithms will, I believe likely, lead to some very uncomforting news for adherents of evolutionary theory - news that could bring that described future closer to our doorsteps - and evolutionists fade into the history books as the mystics of these days... stay tuned. :)

Apoptosis 03.09.2012 Apoptosis

Apoptosis 03.09.2012 Apoptosis
Protein Lounge animations @ http://www.proteinlounge.com/Animation/Animation.aspx

Apoptosis is a cell suicide mechanism that enables metazoans to control cell number in tissues and to eliminate individual cells that threaten the animal's survival. Certain cells have unique sensors, termed Death Receptors, on their surface, which detect the presence of extracellular death signals and, in response, rapidly ignite the cell's intrinsic apoptosis machinery. Cytotoxic T cell with Fas ligand binds to the Fas receptor on target cell and induces apoptosis through a cytoplasmic Death Domain that interacts with signaling adaptors like FADD (Fas-Associated Death Domain). FADD recruits the inactive Procaspase8, which is proteolytically activated to Caspase8, which further cleaves and activate downstream effector Caspase3.

Activated BAX within the mitochondrial membrane leads to creation or alteration of membrane pores, resulting in Mitochondrial-Outer-Membrane Permeabilization that causes release of Cytochrome-C into the cytosol. Cytochrome-C associates with APAF1 protein and Procaspase9 to form the apoptosome, which activates Caspase9, leading to activation of downstream effector caspases, including Caspase3. Caspase3 cleaves ICAD-CAD heterodimer to free CAD to cause DNA fragmentation, thus causing apoptosis.

This animation illustrates the detailed process of apoptosis by extrinsic and intrinsic pathways.

Apoptosis 03.09.2012 Apoptosis
aka Cell Death.  Apoptosis is a process where a cell is degraded in order for it to be ultimately engulfed and recycled.  Apoptosis can occur when a cell has become mutated and is on the verge of becoming a cancer.  Apoptosis is also the reason why we don't have webbed hands and feet.

What basically happens is that the killer t cell communicates with the diseased cell by adhering to it by binding its death ligand to the death receptor on the diseased cell.  This causes adapter proteins to attach to the cytosolic side of the receptor.  This leads to a signal cascade which involves the recruitment of various other proteins and ultimately results in the death of the cell.

ATP Synthase Animation 03.09.2012 ATP Synthase Animation
ATP Synthase the Motor of Life by Nasif Nahle

When we talk about the macroscopic world, we define the term structure from an anatomical, histological and morphological viewpoint. However, we often ignore the fact that we have to make a qualitative jump in the progression from macrophysical systems to microphysical systems. When we investigate the system as a whole, we must not limit our knowledge simply to macrophysical parameters which can be measured, as length, distance, volume, etc., but to effective parameters which are further related with electric charges, electromagnetic fields, quantum energy and electrodynamic phenomena. We set in motion a picture of a macrophysical system, i.e. a plant. We can describe its height, its volume, its weight, the quantity of leaves it has, its color, etc.; however, as we move our observations towards smaller and smaller portions of the macroscopic structure, we arrive at a point at which the macrophysical qualities leap into another realm where the parameters with which we previously classified the living organism no longer have any utility. Of course, the transition is so subtle that many of us succumb to the idea that there is no more physical explanation to describe life. If we understand that there is no boundary, but rather a continuum which links every process in every living system with the Universe, we will not be so easily fooled by the illusion of a separation between the macrophysical world and the microphysical world.

The ATP Synthase Enzyme 03.09.2012 The ATP Synthase Enzyme
http://creation.com
This animated sequence shows the ATP Synthase enzyme in operation. The animation is based on an incredible series of scientific discoveries. Only the colours show artistic licence.

ATP, or Adenosine Tri-Phosphate, is the energy currency of the cell. ATP is produced by a tiny molecular rotary motor, rotating at up to 7,000 rpm. These are so small that 100,000 would fit side-by-side in a millimetre. A current of protons drives the motor, unlike man-made electric motors, which use electrons.

This portion of the enzyme is where Adenosine Di-Phosphate is combined with a phosphate ion, in the presence of a catalyst to produce ATP which is then released, making way for the next cycle. A top view of the enzyme shows the sequential operation. Almost every bio-chemical process in your body requires ATP.

Such a nano-machine exhibits all the characteristics of super-intelligent design. ATP is vital for life and many of these motors were needed before the first living cell could exist. An evolutionary impossibility!
