Coating Scaffold with Self-Assembling Nanofibers Decreases Inflammation

Coating Scaffold with Self-Assembling Nanofibers Decreases Inflammation

A new technique to create tissue-engineered bladders has been shown to decrease scarring and significantly increase tissue growth. The bladders are produced using scaffolds coated with anti-inflammatory peptides. [More]

Disposable Molecular Ruler Helps Determine Length of Bacteria’s Nanoscopic Needle

Disposable Molecular Ruler Helps Determine Length of Bacteria’s Nanoscopic Needle

When a salmonella bacterium attacks a cell, it uses a nanoscopic needle to inject it with proteins to aid the infection. If the needle is too short, the cell won’t be infected. Too long, and the needle breaks. Now, University of Utah biologists report how a disposable molecular ruler or tape measure determines the length of the bacterial needle so it is just right. [More]
Light and Targeted Gold Nanoparticles Can Be Used to Activate Non-Genetically Modified Neurons

Light and Targeted Gold Nanoparticles Can Be Used to Activate Non-Genetically Modified Neurons

Light can be used to activate normal, non-genetically modified neurons through the use of targeted gold nanoparticles, report scientists from the University of Chicago and the University of Illinois at Chicago. The new technique, described in the journal Neuron on March 12, represents a significant technological advance with potential advantages over current optogenetic methods, including possible use in the development of therapeutics toward diseases such as macular degeneration.

Complex ORC Protein Machine is Not Always ‘On’

Complex ORC Protein Machine is Not Always ‘On’

Scientists at Johns Hopkins have created a 3-D model of a complex protein machine, ORC, which helps prepare DNA to be duplicated. Like an image of a criminal suspect, the intricate model of ORC has helped build a "profile" of the activities of this crucial "protein of interest." But the new information has uncovered another mystery: ORC's structure reveals that it is not always "on" as was previously thought, and no one knows how it turns on and off. [More]
Super-Resolution Microscopy Helps Visualise and Count the Smallest Units in the Genome

Super-Resolution Microscopy Helps Visualise and Count the Smallest Units in the Genome

In 1953 Watson and Crick first published the discovery of the double helix structure of the DNA. They were able to visualize the DNA structure by means of X-Ray diffraction. Techniques, such as electron microscopy, allowed scientists to identify nucleosomes, the first and most basic level of chromosome organisation. Until now it was known that our DNA is packaged by regular repeating units of those nucleosomes throughout the genome giving rise to chromatin. [More]
Researchers Determine Molecular Structure of Nanobody-P Domain Complex for Norovirus

Researchers Determine Molecular Structure of Nanobody-P Domain Complex for Norovirus

Infection with highly contagious noroviruses, while not usually fatal, can lead to a slew of unpleasant symptoms such as excessive vomiting and diarrhea. Current treatment options are limited to rehydration of the patient. "Additionally, noroviruses come in a variety of constantly evolving strains. This makes the development of an effective vaccine to protect against infection, as well as antiviral therapy to combat already-existing infections, particularly challenging", says Dr. Grant Hansman, a virologist who leads the CHS Research Group on Noroviruses at the German Cancer Research Center (Deutsches Krebsforschungszentrum, DKFZ) and Heidelberg University.

Fluid-Based Gating Mechanism for Controlling Passage of Materials through Micropores

Fluid-Based Gating Mechanism for Controlling Passage of Materials through Micropores

In nature, pores can continuously control how a living organism absorbs or excretes fluids, vapors and solids in response to its environment; for example, tiny holes invisible to the naked eye called stomata cover a plant's leaves and stems as gated openings through which oxygen, carbon dioxide and water vapors are transported in and out during photosynthesis and respiration. And some scientists have proposed that micropores in the tissues of the air sacs of human lungs can open or close to modulate fluid flow based on changes in air pressure or inflammation. [More]
