In an article published in the peer-reviewed SPIE publication Neurophotonics, 'High density functional diffuse optical tomography based on frequency domain measurements improves image quality and spatial resolution,' researchers demonstrate critical improvements to functional Near Infrared Spectroscopy (fNIRS)-based optical imaging in the brain.
Researchers have developed artificial 'chameleon skin' that changes colour when exposed to light and could be used in applications such as active camouflage and large-scale dynamic displays.
Amyloid fibrils play a crucial role in neurodegenerative illnesses. Scientists from Heinrich Heine University Düsseldorf (HHU) and Forschungszentrum Jülich have now been able to use cryo-electron microscopy (cryo-EM) to decode the spatial structure of the fibrils that are formed from PI3K SH3 domains - an important model system for research. Although the fibrils examined are not themselves connected with an illness, the findings made and methods developed could serve to understand diseases such as Alzheimer's and Parkinson's.
Scientists from Russia, China, and the US have drawn the attention of the scientific community to one of the newest and most promising areas in bioprinting -- laser-induced forward transfer (LIFT). They have compared laser printing parameters, bioink composition, donor ribbons, and collector substrates for LIFT bioprinters, as well as post-printing treatments of fabricated materials -- all of this may affect the properties of printed tissues and organs. The details of the analysis were published in Bioprinting.
When insects carry the pollen from one flower to another to pollinate them, the pollen must attach to and detach from different surfaces. Scientists from Kiel University have discovered that the mechanisms are far more complex than previously assumed. They differ depending on the duration of the contact and the microstructure of the plant surfaces. The results could be interesting for drug delivery and for developing alternative strategies in agriculture and food production.
Together with their Munich-based colleagues, a team of physical chemists from Heinrich Heine University Düsseldorf (HHU) has clarified which chemical reactions take place during PUVA therapy. The therapy involves light-induced damage to the DNA of diseased cells. The team working under Prof. Dr. Peter Gilch has now published its findings in the Journal of the American Chemical Society.
It normally takes about 21 days for chicken embryos to develop into chicks. By observing chicken hindlimb formation, a CNRS / Université de Paris research team has just discovered that the mechanism at the origin of embryonic development consists of a sequence of reflexive contractions. The researchers were able to artificially recreate the same process and accelerate it by as much as a factor of 20.
Monitoring and tracking biological threats or epidemics require the ability to carry out tests in the field during austere situations. Expensive laboratory equipment is often unavailable in these settings, so inexpensive point-of-care technology is needed. Ordinary paper is often used, since it's cheap, portable and widely available. However, paper poses some problems that hinder its usefulness. In this week's Biointerphases, investigators report a technique that greatly improves the performance of paper-based point-of-care technologies.
Using ultrasonic tweezers, live imaging and a micro-mechanical substrate, NYU Tandon researchers found energy patterns in cellular allostasis that could predict the presence of disease.
DGIST Professor Jaeheung Cho in the Department of Emerging Materials Science secured materials that lead aldehyde deformylation reaction. Confirmed the nucleophilic reactions by biomimetic materials... Expects to bring positive impacts on related research.
