Significant new capability added to the HELM biomolecular representation standard. Wilmington, DE (PRWEB) July 01, 2014 The Pistoia Alliance and quattro research are pleased to announce the release of an extension to the HELM biomolecular representation standard. HELM (Hierarchical Editing Language for Macromolecules) enables the representation of a wide range of biomolecules (e.g. proteins, nucleotides, antibody drug conjugates) whose size and complexity render existing small-molecule...

New Microscopy Method Could Spot Dozens Of Distinct Types Of Biomolecules Simultaneously

Wyss Institute for Biologically Inspired Engineering at Harvard A new microscopy method could enable scientists to generate snapshots of dozens of different biomolecules at once in a single human cell, a team from the Wyss Institute of Biologically Inspired Engineering at Harvard University reported Sunday in Nature Methods. Such images could shed light on complex cellular pathways and potentially lead to new ways to diagnose disease, track its prognosis, or monitor the effectiveness of...

Clay May Have Been Cradle Of Life

[ Watch the Video: Life On Earth May Have Come From Clay ] Brett Smith for redOrbit.com - Your Universe Online Often viewed as an apparently infertile blend of various minerals, clay might have actually been the birthplace of life on Earth, biological engineers from Cornell University report in new research appearing in Thursday’s online edition of the journal Scientific Reports. The study authors set out to simulate ancient seawater in order to analyze the properties of clay under...

The traditional way of making medicines from ingredients mixed together in a factory may be joined by a new approach in which doctors administer the ingredients for a medicine separately to patients, and the ingredients combine to produce the medicine inside patients' bodies. That's one promise from an emerging new field of chemistry, according to the scientist who founded it barely a decade ago. Carolyn Bertozzi, Ph.D., spoke on the topic – bioorthogonal chemistry – here today...

Mechanism of evolution of the primordial metabolism discovered Volcanic-hydrothermal flow channels offer a chemically unique environment, which at first glance appears hostile to life. It is defined by cracks in the crust of the earth, through which water flows, laden with volcanic gases are contacting a diversity of minerals. And yet — it is precisely this extreme environment, where the two mechanisms could have emerged, which are at the root of all life: The multiplication of...

New approach to continuous directed evolution roughly 100 times faster than previously possible Scientists at Harvard University have harnessed the prowess of fast-replicating bacterial viruses, also known as phages, to accelerate the evolution of biomolecules in the laboratory. The work, reported this week in the journal Nature, could ultimately allow the tailoring of custom pharmaceuticals and research tools from lab-grown proteins, nucleic acids, and other such compounds. The researchers,...

Biomolecules are medicine's jacks-of-all-trades: They are suitable for the diagnosis and treatment of cancer diseases; they are used in the treatment of multiple sclerosis and asthma; they help stimulate the build-up of the body's own immune defenses with flu and polio inoculations. In the laboratories of the pharmaceutical industry, new biomolecules are constantly being engineered: Specific antibodies, customized proteins and nucleic acids "“ the core components of genetic material -...

Physicists, chemists and engineers at the University of Pennsylvania have demonstrated a novel method for the controlled formation of patchy particles, using charged, self-assembling molecules that may one day serve as drug-delivery vehicles to combat disease and perhaps be used in small batteries that store and release charge. Researchers demonstrated that the positive electrical charges of calcium ions "” just like the calcium in teeth and bone "” can form bridges between...

Genetic modification of bacterium results in alcohols with greater energy For the first time, researchers at the UCLA Henry Samueli School of Engineering and Applied Science have successfully pushed nature beyond its limits by genetically modifying Escherichia coli, a bacterium often associated with food poisoning, to produce unusually long-chain alcohols essential in the creation of biofuels. "Previously, we were able to synthesize long-chain alcohols containing five carbon atoms," said...

An important discovery has been made with respect to the mystery of "handedness" in biomolecules. Researchers led by Sandra Pizzarello, a research professor at Arizona State University, found that some of the possible abiotic precursors to the origin of life on Earth have been shown to carry "handedness" in a larger number than previously thought. The work is being published in this week's Early Edition of the Proceedings of the National Academy of Sciences (PNAS). The paper is titled,...


Word of the Day
cenobite
  • One of a religious order living in a convent or in community; a monk: opposed to anchoret or hermit (one who lives in solitude).
  • A social bee.
