A New Thermodynamics Theory of the Origin of Life | Quanta Magazine
Besides self-replication, greater structural organization is another means by which strongly driven systems ramp up their ability to dissipate energy. A plant, for example, is much better at capturing and routing solar energy through itself than an unstructured heap of carbon atoms. Thus, England argues that under certain conditions, matter will spontaneously self-organize. This tendency could account for the internal order of living things and of many inanimate structures as well. “Snowflakes, sand dunes and turbulent vortices all have in common that they are strikingly patterned structures that emerge in many-particle systems driven by some dissipative process,” he said. Condensation, wind and viscous drag are the relevant processes in these particular cases.

Mystery of Lifes Origin
If the author's criticisms are valid, one might ask, why have they not been recognized or stressed by workers in the field? I suspect that part of the answer is that many scientists would hesitate to accept the authors' conclusion that it is fundamentally implausible that unassisted matter and energy organized themselves into living sys­ tems. Perhaps these scientists fear that acceptance of this conclu­ sion would open the door to the possibility (or the necessity) of a supernatural origin of life. Faced with this prospect many investiga­ tors would prefer to continue in their search for a naturalistic expla­ nation of the origin of life along the lines marked out over the last few decades, in spite of the many serious difficulties of which we are now aware. Perhaps the fallacy of scientism is more widespread than we like to think.

How Things End: Entropy - Life Lesson Processing (LLP) Theory Tour - Mental Training Workgroup, Austria - Life Lessons, LLP Theory, Matter, Entropy, Healthy Old Age
Quite a bit of struggle and pain is involved in the process of shrinking and dying if it is a human being's body (animals are much more at peace with their death). This can be explained with the two different energies that combine in a life form: the spiritual being, and the biological organism. A human body for instance has a genetically programmed life span of about 120 years. Realistically, with the many errors that we currently make in diet and lifestyle, it is more like 90 years. We could assume that the body grows for 20 years - creativity prevails. Then it lives and works for 50 years - growth and entropy are balanced. Then it goes through 20 years of entropy taking over, its cells and organs slowly stop repairing themselves, the body more and more follows the urge to rest, it is phasing out and finally dies.

What are 90 years for a spiritual being, who lives for countless human years? Nothing - just the blink of an eye! It enjoys a lot the lively activities of the body's younger years and still feels comfortable while growth and entropy are balanced, but when the physical body starts to phase out and increasingly follows the urge to rest that has been genetically programmed into it, the spirit is less and less in agreement. More and more he is frustrated with the body's decay, more and more protest builds up, until he makes a final cut and leaves in the act of dying, looking for the next young body if he still wants more of these exciting adventures in the physical.

Were he to look back at all, he might be fascinated by the fact that while the body now seems to be at a point of ultimate rest, far beyond the point of no return, this is not so - not at all! In the very next moment, tiny life forms (microbes) take over, start to eat it, and immediately recycle its molecules into their own minuscule organisms. Biological life does not rest for a minute. From a big structure it dances all the way back to a small one; from complicated to simple; from dead to alive! It will be a long time before life gets tired of this eternal ballet between acting and resting, and follows the urge to rest to a point of absolute, total and infinite silence... until the next Grand Cycle begins.

Entropy Production and the Origin of Life
All irreversible processes arise and persist to produce entropy. Entropy production is not incidental to such processes, but rather the very reason for their origin and persistence. Here we take such a thermodynamic perspective on the origin of life, recognizing that entropy production is not only the vital force of life, but the fundamental link between life in the biosphere today and its origin in the Archean. Today the greatest en-tropy production in the biosphere is due to visible photon absorption and dissipation into heat by organic material in liquid water and the subsequent degradation of the established heat gradient through the water cycle. Following this link back in time to the Archean environment leads to a suggestion for a mechanism for the origin of life based on UV photon absorption and dissipation by RNA and DNA.

Sarcoma Alliance: Physics and math bring more precision to treatment
Dr. Jeremy Mason
My mentor at a cancer conference has taken only one biology class in his life, and that was when he was a freshman in high school. Nevertheless, his knowledge can change the way you think of cancer — and the way doctors treat it.

“Math, physics and computer science have a profound impact on the field of cancer research today,” said Jeremy Mason, who has his doctorate in engineering. “Other scholars with little to no experience in cancer are applying their own knowledge and skills to build detailed and relevant models of the event prediction, cellular birth/death processes, therapeutic responses and much more.

“One day, these models will be used for the common goal of improving patient care and extending lives.”

The Metallic Vapor Layers
A natural global layer (usually about 3 miles thick) of sodium atoms exists between about 50 and 65 miles (80 and 105 km) altitude. The sodium originates from the ablation of meteors. The atoms are naturally excited and emit a weak glow near a wavelength of 589 nm (yellow) known as "the sodium D lines". Above the layer, sodium exists in its ionized form (which does not emit yellow light) and below the layer, sodium exists as chemical compounds such as sodium oxide (which also do not emit yellow light).

Single-shot real-time femtosecond imaging of temporal focusing | Light: Science & Applications
While the concept of focusing usually applies to the spatial domain, it is equally applicable to the time domain. Real-time imaging of temporal focusing of single ultrashort laser pulses is of great significance in exploring the physics of the space–time duality and finding diverse applications. The drastic changes in the width and intensity of an ultrashort laser pulse during temporal focusing impose a requirement for femtosecond-level exposure to capture the instantaneous light patterns generated in this exquisite phenomenon. Thus far, established ultrafast imaging techniques either struggle to reach the desired exposure time or require repeatable measurements. We have developed single-shot 10-trillion-frame-per-second compressed ultrafast photography (T-CUP), which passively captures dynamic events with 100-fs frame intervals in a single camera exposure. The synergy between compressed sensing and the Radon transformation empowers T-CUP to significantly reduce the number of projections needed for reconstructing a high-quality three-dimensional spatiotemporal datacube. As the only currently available real-time, passive imaging modality with a femtosecond exposure time, T-CUP was used to record the first-ever movie of non-repeatable temporal focusing of a single ultrashort laser pulse in a dynamic scattering medium. T-CUP’s unprecedented ability to clearly reveal the complex evolution in the shape, intensity, and width of a temporally focused pulse in a single measurement paves the way for single-shot characterization of ultrashort pulses, experimental investigation of nonlinear light-matter interactions, and real-time wavefront engineering for deep-tissue light focusing.
