Scientists writing in Developmental Cell say they have identified a master regulator gene for early embryonic development of the pancreas and other organs, putting researchers closer to coaxing stem cells into pancreatic cells and then a possible cure for Type 1 Diabetes.

They say this discovery reverses a long standing belief that the biliary system's origin is connected to early embryonic formation of the liver, the researchers said. The pancreas regulates digestion and blood sugar, and the biliary system is vital for digestion. If the organs do not form properly during fetal development, it can be fatal.

A new micro-tool allows researchers to measure and manipulate cellular forces as assemblies of living cells reorganize themselves into tissues.  The new technique allows researchers to gauge how cells' minute mechanical forces affect cellular behavior and cell differentiation in a 3-D, in vivo-like environment.  It mimics how tissue actually forms in a living organism.

The push-and-pull of cellular forces drives the deformation, extension and contraction of cells that occur during tissue development and these processes ultimately shape the architecture of tissues so how it is done plays an important role in coordinating cell signaling, gene expression and behavior, and they are essential for wound healing and tissue homeostasis in adult organisms.

"It's not supposed to do that" - Sandia principal investigator Jack Houston.

Researchers from Sandia National Laboratories and the University of Pittsburgh have found they can make salt, a solid, physically stretch.  

"Unlike, say, gold, which is ductile and deforms under pressure, salt is brittle. Hit it with a hammer, it shatters like glass, " says Houston.

Labyrinthulomycetes, single-celled marine decomposers that eat non-living plant, algal, and animal matter, are ubiquitous and abundant, particularly on dead vegetation and in salt marshes and mangrove swamps.

Although most labyrinthulomycetes species are not pathogens, the organisms responsible for eelgrass wasting disease and QPX disease in hard clams are part of this group. 

Before we can begin to implement sustainable, carbon-neutral gasoline - "grassoline" - from inedible plant material like fast-growing weeds and agricultural waste, some technology hurdles have to be overcome.  Namely, finding better ways to break lignocellulosic biomass down into fermentable sugars.

Over 60 percent of the nearly 5,000 genome projects reported in the Genomes OnLine Database involve microbes.   It's no surprise.   Microbes are important in everything from bioenergy to agriculture and medicine and are involved in Earth’s biogeochemical cycles.

A lot could be done with microbial genomics, says DOE JGI Genome Biology head Nikos Kyrpides writing in Nature Biotechnology, if researchers go beyond the present anthropocentric focus and institute shared standards for genomic data collection and analysis.

University of Haifa-Oranim researchers have managed to make out the “self-irrigating” mechanism of Rumex hymenosepalus, the desert rhubarb, which enables it to harvest 16 times the amount of water than otherwise expected for a plant in this region based on the quantities of rain in the desert - the first example of a self-irrigating plant worldwide.

The desert rhubarb grows in the mountains of Israel’s Negev desert, where average precipitation is particularly low (75 mm per year). Unlike most of the other desert plant species, which have small leaves so as to minimize moisture loss, this plant is unique in that its leaves are particularly large; each plant’s rosette of one to four leaves reaches a total diameter of up to one meter.

Dye-sensitized solar cells (DSSCs), expected to power Air Force unmanned aerial vehicles (UAVs) in the future because they are an optimum energy harvesting source that may lead to longer flight times without refueling, have gotten a boost  by using a flexible film and a thin glass coating with transparent conductive electrodes.

The University of Washington's Multidisciplinary University Research Initiative (MURI) project team, with lead researcher Dr. Minoru Taya is working on the airborne solar cells and found that DSSCs made from organic materials, which use (dyes) and moth-eye film, are able to catch photons and convert them into synthesized electrons that can harvest high photon energy. 

This topic requires many considerations that may be more political than economic, but to try and retain focus, the point is primarily to examine how economic principles (like supply and demand) are dealt with in this arena.

There are two ways in which multi-national businesses may manifest. In one case, a company maintains operations to provide goods and services in another country and is completely self-contained. In other words, the goods/services provided are provided by individuals in that country for individuals in that country. This is simply another closed system(1), albeit with a company that originated elsewhere.

In another post the general discussion regarding free will seemed to teeter on the edge of a definition that recognized the significant role that our genes and indoctrination played, while allowing some "wiggle" room for something like free will to emerge. However this also lead me to wonder about the role of determinism in this, because ultimately the argument against free will is based on the idea that we are defined by our genes and teachings, so whatever we do is inevitable.
