Complex Organic Molecules

Authors: George Rajna
Comments: 49 Pages.

Using mass spectrometry data from NASA's Cassini spacecraft, scientists found that large, carbon-rich organic molecules are ejected from cracks in the icy surface of Saturn's moon Enceladus. [30] Absorption of light energy by large molecules is what drives nature: photosynthesis, vision, the synthesis of vitamin D and many other critical processes use light energy to perform their functions. [29] A University of Central Florida team has designed a nanostructured optical sensor that for the first time can efficiently detect molecular chirality—a property of molecular spatial twist that defines its biochemical properties. [28] UCLA scientists and engineers have developed a new process for assembling semiconductor devices. [27] A new experiment that tests the limit of how large an object can be before it ceases to behave quantum mechanically has been proposed by physicists in the UK and India. [26] Phonons are discrete units of vibrational energy predicted by quantum mechanics that correspond to collective oscillations of atoms inside a molecule or a crystal. [25] This achievement is considered as an important landmark for the realization of practical application of photon upconversion technology. [24] Considerable interest in new single-photon detector technologies has been scaling in this past decade. [23] Engineers develop key mathematical formula for driving quantum experiments. [22] Physicists are developing quantum simulators, to help solve problems that are beyond the reach of conventional computers. [21] Engineers at Australia's University of New South Wales have invented a radical new architecture for quantum computing, based on novel 'flip-flop qubits', that promises to make the large-scale manufacture of quantum chips dramatically cheaper-and easier-than thought possible.

Link Between Cancer and Aging

Authors: George Rajna
Comments: 58 Pages.

The discovery could help us better understand aging and eventually could lead to new treatments for cancer. [31] A research team at the University of Delaware, led by Emily Day, an assistant professor of biomedical engineering, is laying the groundwork for a method to inhibit cancer-promoting genes in cancer cells while leaving healthy cells intact. [30] Researchers have moved closer to the real-time verification of hadron therapy, demonstrating the in vivo accuracy of simulations that predict particle range in the patient. [29] A biomimetic nanosystem can deliver therapeutic proteins to selectively target cancerous tumors, according to a team of Penn State researchers. [28] Sunlight is essential for all life, and living organisms have evolved to sense and respond to light. [27] Using X-ray laser technology, a team led by researchers of the Paul Scherrer Institute PSI has recorded one of the fastest processes in biology. [26] A Virginia Commonwealth University researcher has developed a procedure for identifying the source of cells present in a forensic biological sample that could change how cell types are identified in samples across numerous industries. [25] In work at the National Institute of Standards and Technology (NIST) and the University of Maryland in College Park, researchers have devised and demonstrated a new way to measure free energy. [24] A novel technique developed by researchers at the ARC Centre of Excellence for Nanoscale BioPhotonics (CNBP) will help shine new light on biological questions by improving the quality and quantity of information that can be extracted in fluorescence microscopy. [23] Micro-computed tomography or "micro-CT" is X-ray imaging in 3-D, by the same method used in hospital CT (or "CAT") scans, but on a small scale with massively increased resolution. [22]

Microelectrode Array Sensors

Authors: George Rajna

Microelectrodes can be used for direct measurement of electrical signals in the brain or heart.

Regulation of Oligopeptide Transporter Pept1 (Slc15a1) in Disease and Application in Clinical Nutrition

Authors: Ming-Yi Liu
Comments: 11 Pages.

Many studies have demonstrated the di- and tripeptides is a major mechanism by which the digestion products of proteins are absorbed. The oligopeptide transporter PepT1 is localized to the brush-border membrane and mediates the absorption in mammalian intestine. Recently, regulations of PepT1 activity by a variety of pathological conditions have been studied. Critical illness, malnutrition and metabolic disorder could induce the modulation of protein and gene expressions of PepT1. We reviewed and analyzed by searching PubMed, google scholar database and reference literature to provide a theoretical basis for clinical nutrition support.

The Convection Principle of Life Formation

Authors: Jeffrey Joseph Wolynski
Comments: 2 Pages.

A branch to the volume principle of life formation is offered. Essentially to form life, not only are large volumes of moving fluid required, whether it is gas or liquid material, but that that fluid needs to convect on large scales. This signals large scale heat transfer, which can be removed from needing to orbit a hotter host.

The Unquestioned, Unacknowledged Assumptions of Panspermia and All of its Variants

Authors: Jeffrey Joseph Wolynski
Comments: 2 Pages.

The unquestioned and unacknowledged assumption of panspermia or directed panspermia is that all interstellar bodies are sterile before they host life, and interstellar bodies can be great, habitable hosts but as sterile as an operating table simultaneously.

Goldmine DNA Database

Comments: 33 Pages.

A microscopic thread of DNA evidence in a public genealogy database led California authorities to declare this spring they had caught the Golden State Killer, the rapist and murderer who had eluded authorities for decades. [19] Researchers at Delft University of Technology, in collaboration with colleagues at the Autonomous University of Madrid, have created an artificial DNA blueprint for the replication of DNA in a cell-like structure.

[15] Scientists from Moscow State University (MSU) working with an international team of researchers have identified the structure of one of the key regions of telomerase—a so-called "cellular immortality" ribonucleoprotein. [14] Researchers from Tokyo Metropolitan University used a light-sensitive iridium-palladium catalyst to make "sequential" polymers, using visible light to change how building blocks are combined into polymer chains. [13] Researchers have fused living and non-living cells for the first time in a way that allows them to work together, paving the way for new applications. [12] UZH researchers have discovered a previously unknown way in which proteins interact with one another and cells organize themselves. [11] Dr Martin Sweatman from the University of Edinburgh's School of Engineering has discovered a simple physical principle that might explain how life started on Earth. [10] Nearly 75 years ago, Nobel Prize-winning physicist Erwin Schrödinger wondered if the mysterious world of quantum mechanics played a role in biology. A recent finding by Northwestern University's Prem Kumar adds further evidence that the answer might be yes. [9]

Microbes Survive Clean Rooms

For planetary protection, this indicates that more stringent cleaning steps may be needed for missions focused on life detection and highlights the potential need to use differing and rotating cleaning reagents that are compatible with the spacecraft to control the biological burden.

DNA-Based Robots

Comments: 36 Pages.

Researchers have devised a magnetic control system to make tiny DNA-based robots move on demand—and much faster than recently possible. [21] Humans have 46 chromosomes, and each one is capped at either end by repetitive sequences called telomeres. [20] Just like any long polymer chain, DNA tends to form knots. Using technology that allows them to stretch DNA molecules and image the behavior of these knots, MIT researchers have discovered, for the first time, the factors that determine whether a knot moves along the strand or "jams" in place. [19] Researchers at Delft University of Technology, in collaboration with colleagues at the Autonomous University of Madrid, have created an artificial DNA blueprint for the replication of DNA in a cell-like structure. [18] An LMU team now reveals the inner workings of a molecular motor made of proteins which packs and unpacks DNA. [17] Chemist Ivan Huc finds the inspiration for his work in the molecular principles that underlie biological systems. [16] What makes particles self-assemble into complex biological structures?

A recent finding by Northwestern University's Prem Kumar adds further evidence that the answer might be yes. [9]
