A new study shows where Himalayan-Tibetan Plateau soot pollution comes from. Warming the region enough to melt snow earlier and shrink glaciers, the soot can impact water for millions in Asia. The research can help policy makers target the most effective pollution reduction efforts. Read more at http://www.pnnl.gov/news/release.aspx?id=4215.

PNNL scientists have solved a difficult problem for research: Why do certain catalytic reactions simply not happen as calculated?  The research team used three prototypical reactions on a titanium dioxide surface and demonstrated that reactions will happen only with additional energy, such as heat or light.  By looking at the excited states along the reaction, the team saw a cusp on the lowest energy pathway, indicating the reaction can happen only after the system is excited to a higher energy state. This study will help scientists accurately model catalytic reactions on titania and other reducible oxides that are frequently used in industry.

I'll try.  Your subject "evolution" is an abstraction in a strict sense, from the verb that I distinguished informally.  You lost me as your subject changed into some exploration of "complexity" which might have implied the problem of how "advanced" species might have evolved from simpler forms (like microbes, say)---but what was you standard for "simplicity"?  Then your subject changes into a discussion of language that focuses on English specifically without any reference to the "problem of universals" which was once essential to the logic of "scientific method" before it degenerated into rationales for experimentation.  What happened to evolution?  Are you talking about an evolution of life generally out of matter abstractly or the evolution of shapes and forms from common origins - or at any certain point in time, including the present?

When you don't define your topic in any clear or distinctive sense, you end up tracing accepted doctrine toward no conclusions.  There is always something more general in nature than anything you might mean subjectively.  What is NOT evolution in your universe, implicitly, that must be "complex" in such an indefinite sense.  Are you sure the evolution of modern diction out of British English is the proper way to relate language to complexity?  How you propose to return from such abstractions to the problems that Darwin introduced to understanding the emergence of life on our planet?  Maybe I didn't get it because you lost my attention in a hash of ideas with no theme. On the other hand, there is such a thing as "involution" in projective geometry which bears an interesting relation to the "vortices" of Cartesian principles, notwithstanding how the "Cartesian Plane" has been distorted into something it's not for anyone who ever studied Analytic Geometry.  Without any formal basis in common understandings, the religious versus scientific debate about semantic differences  doesn't prove very meaningful in lectures.

Scientists can now see structured communities of microbes known as biofilms in 3D and in real time thanks to a microfluidic reactor developed at PNNL. The System for Analysis at the Liquid Vacuum Interface (SALVI) recently produced the first 3D images of live biofilms using time-of-flight secondary ion mass spectrometry, providing a fresh view of these complex structures.

Researchers in The Edward S. Rogers Sr. Department of Electrical & Computer Engineering used this insight to invent something totally new: they’ve combined two promising solar cell materials together for the first time, creating a new platform for LED technology.
The team designed a way to embed strongly luminescent nanoparticles called colloidal quantum dots (the chocolate chips) into perovskite (the oatmeal cookie). Perovskites are a family of materials that can be easily manufactured from solution, and that allow electrons to move swiftly through them with minimal loss or capture by defects.

Following the 2013 Sichuan flood in southwest China, researchers found that heavy air pollution over the Sichuan Basin contributed to the catastrophic flood. Through a series of events they call “aerosol-enhanced conditional instability,” tiny particles from heavy air pollution absorb heat from the sun, stabilize the atmosphere and suppress local storms during the daytime. However, this allows the heavy moist – and now warm air – to be transported downwind to mountainous areas where it is lifted, causing extreme evening precipitation. This research was published in Geophysical Research Letters and highlighted by the journal Nature. Read more at http://www.pnnl.gov/science/highlights/highlight.asp?id=4042.

When aluminum atoms bunch up, porous materials called zeolites lose their ability to convert oil to gasoline. An international team, including scientists at PNNL, created the first 3-D atomic map of a zeolite to find out how to improve catalysts used to produce fuel, biofuel and other chemicals.

Scientists have long worked to understand how crystals grow into complex shapes. Now, an international group of researchers has shown how nature uses a variety of pathways to grow crystals that go beyond the classical, one-atom-at-a-time route. By understanding how animals form crystals into working structures – such as shells, teeth and bones – scientists can better interpret crystals formed in nature. The insights may also help in the design of novel materials and explain unusual mineral patterns in rocks. Likewise, knowing how pollutants are transported or trapped in the minerals of sediments has implications for environmental management of water and soil.

With their warm, waterlogged soils, rice paddies contribute up to 17 percent of global methane emissions, the equivalent of about 100 million tons each year. With the addition of a single gene, rice can be cultivated to emit virtually no methane from its paddies during growth. Read more at http://www.pnnl.gov/news/release.aspx?id=4214.

PNNL scientists have directed a common bacterium to produce more lauric acid – a valuable fatty acid – than it typically does. The achievement is noteworthy not simply because of the increased production of fatty acid, which can be a useful component of biofuels, but it also opens the door for scientists to manipulate such organisms to produce compounds useful as fuels or medicines.  Read more at https://www.pnnl.gov/science/highlights/highlight.asp?id=4060.

Like coffee? Unbelievably, there is a beetle that lives on nothing but coffee! The coffee berry borer consumes toxic levels of caffeine without even getting jittery. Researchers have figured out why, and the answer may lead to a way to stop this pest from destroying the coffee crop.
Can you imagine living off nothing but coffee? Some of us probably feel like we do at times, if not for the taste then for the buzz the caffeine brings. Caffeine makes us feel more alert because it structurally resembles a mo...

Throw away the detergent and forgo the elbow grease: pesky proteins can now be removed from surfaces by simply exposing them to light, thanks to a reusable titania template developed by A*STAR researchers1.

A multi-institutional team of researchers led by the U.S. Department of Energy (DOE)’s Lawrence Berkeley National Laboratory (Berkeley Lab), has developed a new technique called “SINGLE” that provides the first atomic-scale images of colloidal nanoparticles. SINGLE, which stands for 3D Structure Identification of Nanoparticles by Graphene Liquid Cell Electron Microscopy, has been used to separately reconstruct the 3D structures of two individual platinum nanoparticles in solution
                                                                     SINGLE uses in situ TEM imaging of platinum nanocrystals freely rotating in a graphene liquid cell to determine the 3D structures of individual colloidal na...

How clouds form and how they help set the temperature of the earth are two of the big remaining questions in climate research. Now, a study of clouds over the world's remotest ocean shows that ocean life is responsible for up to half the cloud droplets that pop in and out of existence during summer.
