Changes in the molecular structure of iron ore in the Earth's core could mean that Earth has a layer of liquid oxygen, with 10 times as much oxygen as the entire atmosphere.
Lincoln, Neb., Feb. 12, 2016 -- Amid the season known for transforming Nebraska into an outdoor ice rink, a University of Nebraska-Lincoln-led research team has predicted a new molecular form of the slippery stuff that even Mother Nature has never borne. The proposed ice, which the researchers describe in a Feb. Show More Summary
BOSTON (Feb. 11, 2016) - The genome of developing brain cells harbors 27 clusters or hotspots where its DNA is much more likely to break in some places than others, researchers from the Program in Cellular and Molecular Medicine (PCMM) at Boston Children's Hospital, Harvard Medical School, and the Howard Hughes Medical Institute report in the journal Cell. read more
Plasmas are typically hot, often generated by heating gasses to the point that molecular bonds break and ions in large quantities are created. While plasmas can be used to sterilize objects, the heat can destroy the very objects being cleaned. Show More Summary
Sean B. Carroll is coming out with a new book called The Serengeti Rules: The Quest to Discover How Life Works and Why It Matters. This is the molecular biologist Sean Carroll, as distinct from the physicist (who wrote this). Homeostasis is one of the basic principles of biology. The term can be applied broadly…
Herbig-Haro 110 is a geyser of hot gas from a newborn star that splashes up against and ricochets off the dense core of a cloud of molecular hydrogen. Although the plumes of gas look like whiffs of smoke, they are actually billions of times less dense and several light-years across. Source: hubblesite.org via Buzzfeed The post Herbig-Haro 110 appeared first on The Big Picture.
Researchers study the link between malformations of the cerebral cortex and the occurrence of the neurological disease. Why does a structural irregularity in the temporal lobe make humans more susceptible to epileptic seizures? Experts have been searching for the answer to this question for a long time.

An international team of scientists led by the University of Liverpool has produced a 'structural movie' revealing the step-by-step creation of an important naturally occurring chemical in the body that plays a role in some cancers. S-Adenosylmethionine...Show More Summary
A healthy heart regulates itself so that with each beat, it pumps out as much blood as it receives. In a finding that could lead to new drugs to treat heart failure, researchers have uncovered the molecular mechanism that regulates how the heart pumps blood.

MAYWOOD, Il. (Feb. 8, 2016) - In a finding that could lead to new drugs to treat heart failure, researchers have uncovered the molecular mechanism that regulates how the heart pumps blood. read more
New close-up images of the proteins that copy DNA inside the nucleus of a cell have led a team of scientists to propose a brand new mechanism for how this molecular machinery works. The scientists studied proteins from yeast cells, which share many features with the cells of complex organisms such as humans, and could offer new insight into ways that DNA replication can go awry.
Protein that gives blood vessels and skin their stretchability has its molecular properties revealed.
Researchers from the Hospital del Mar Medical Research Institute (IMIM) have found an epigenetic mechanism implicated in the regulation of blood sugar. The study, published in the journal Molecular Human Genetics, reveals that the methylation of the TXNIP gene is associated with diabetes mellitus type 2 and, in particular, average blood glucose levels. read more
A new study sheds light on unique property of 2-D materials -- ability to shield chemical interactions at the molecular level. Discovery of shielding effect allows scientists to control reactivity of molecules, tune activity of catalysts, and construct new generation of carbon materials.
Joint theoretical and experimental study suggested that graphene sheets efficiently shield chemical interactions. One of the promising applications of this phenomenon is associated with im-proving quality of 2D materials by "de-charging" of charged defect centers on the surface of carbon materials.

Scientists show that a gene called 'DISC1,' which is believed to play a role in mental health disorders, such as schizophrenia, bipolar disorder and some forms of depression, influences the function of pancreatic beta cells which produce insulin to maintain normal blood glucose levels.
I struggle with the word "wellness." As a term it doesn't land on me with the same gravity as other words that capture the historical moment we are in. As a mantra, Assata Shakur's invocation of the words "duty," "freedom," "win," and "love" build connection, are invigorating, and do something undeniably molecular in their impact. Show More Summary
