How molecular entanglements determine the structure of polymers
The structure of semicrystalline polymers largely depends on how strongly their molecular chains are entangled. This has been shown in a new study by researchers from Martin Luther University Halle-Wittenberg (MLU), which was published in the journal.....»»
Predicting molecular rotational temperature for enhanced plasma recombination
Humans may never be able to tame the sun, but hydrogen plasma—making up most of the sun's interior—can be confined in a magnetic field as part of fusion power generation: with a caveat......»»
Fungi that break down hardwood trees can do the same with plastic, study shows
A team of plant and molecular biologists from the University of Kelaniya and the University of Peradeniya, both in Sri Lanka, reports that many types of fungi that break down hardwood trees can also break down polyethylene, a common kind of plastic......»»
Bio-reactivity of refractory humic-like dissolved organic matter found to increase in energy-limiting deep-sea sediments
Humic-like dissolved organic matter (DOM) is a major component of DOM in marine sediment pore waters. It is usually regarded as refractory for their complex molecular structures and long residence time in natural environments. However, its bio-reacti.....»»
High-resolution scattering imaging reveals vibrational-state-specific mechanisms in paradigmatic ion-molecule reaction
Charged atomic and molecular species are ubiquitous in environments such as planetary atmospheres, interstellar medium and plasma. The collisions between charged ions and neutral molecules play vital roles in determining the chemical evolution and en.....»»

A new study determines the efficiency of a single-molecule heat engine by considering a series of ratchets that transfer energy along a network......»»
Molecular highway for electrons in organic light-emitting diodes: Researchers develop new material concept
Organic light-emitting diodes (OLEDs) are now widely used. For use in displays, blue OLEDs are additionally required to supplement the primary colors red and green. Especially in blue OLEDs, impurities give rise to strong electrical losses, which cou.....»»
Red algae proteins grafted into tobacco double plant growth
A Cornell researcher and her colleagues have solved one key piece of the molecular puzzle needed to dramatically improve plant productivity and increase carbon sequestration: They have successfully transferred key regions of a highly efficient red al.....»»
Researchers capture atomic view of synthetic DNA, revealing "molecular scissors" that could treat disease
West Virginia University researchers are now able to view synthetic DNA at the atomic level, giving them the ability to understand how to change its structure in hopes of enhancing its scissor-like function. Learning more about these synthetic DNA re.....»»
How an unlikely amphibian survived its judgment day
An international team of researchers has uncovered "unprecedented" snake venom resistance in an unexpected species—the legless amphibians known as caecilians. The research has been published in the International Journal of Molecular Sciences......»»
Zooming across time and space simultaneously with superresolution to understand how cells divide
Cell division, or the process of how daughter cells emerge from a mother cell, is fundamental to biology. Every cell inherits the same protein and DNA building blocks that make up the cell it originally came from. Yet exactly how these molecular buil.....»»
Molecular biologists identify framework for understanding RNA editing in a disease-causing parasite
