The world of health care is changing rapidly and there is increased interest in the role that light and lighting can play in improving health outcomes for patients and providing healthy work environments for staff, according to many researchers. Recently, the Center for Lighting Enabled Systems & Applications (LESA) at Rensselaer Polytechnic Institute, together with the Illumination Engineering Society (IES), sponsored a workshop to explore pathways to define and promote the adoption of lighting systems specifically for health-care environments.
Inspired by the human eye, researchers at the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) have developed an adaptive metalens, that is essentially a flat, electronically controlled artificial eye. The adaptive metalens simultaneously controls for three of the major contributors to blurry images: focus, astigmatism, and image shift.
Harvard researchers have developed a metasurface, comprised of a single planar layer of nanostructures, which exhibits strong optical chirality in transmission. This means it can let circularly polarized light of one polarization pass through almost unhindered, while light of the opposite helicity is completely diffracted away. Such capabilities are incredibly useful for a host of applications, such as circular dichroism spectroscopy in the analysis of drug samples, and polarization filters in telecommunications. This work challenges some long-held notions about chiral metamaterials and metasurfaces.
A research team at the University of California, Riverside has discovered a way for chemotherapy drug paclitaxel to target migrating, or circulating, cancer cells, which are responsible for the development of tumor metastases. Until now, paclitaxel has only been used to target rapidly dividing cancer cells. The team was successful in getting the drug to piggyback on 123B9, an agent they devised to target an oncogene called EphA2.
Researchers from CIC nanoGUNE (San Sebastian, Spain), in collaboration with the Donostia International Physics Center (DIPC, San Sebastian, Spain) and Kansas State University (USA), report in Science the development of a so called 'hyperbolic metasurface' on which light propagates with completely reshaped wafefronts. This scientific achievement towards a more precise control and monitoring of light is highly interesting for the long run technological challenge of miniaturizing optical devices for sensing and signal processing.
Johns Hopkins scientists invent multifunctional antibody-ligand traps (Y-traps), a new class of cancer immunotherapeutics. They develop Y-traps comprising an antibody targeting an immune checkpoint (CTLA-4 or PD-L1) fused to a TGFβ trap. In humanized mouse models, these Y-traps reverse immune suppression and inhibit growth of tumors that do not respond to current immune checkpoint inhibitors.
Creating the perfect wearable device to monitor muscle movement, heart rate and other tiny bio-signals without breaking the bank has inspired scientists to look for a simpler and more affordable tool. Now, a team of researchers at UBC's Okanagan campus have developed a practical way to monitor and interpret human motion, in what may be the missing piece of the puzzle when it comes to wearable technology.
A new technique developed by neuroscientists at U of T Scarborough can reconstruct images of what people perceive based on their brain activity gathered by EEG.
Using advanced computational methods, University of Wisconsin-Madison materials scientists have discovered new materials that could bring widespread commercial use of solid oxide fuel cells closer to reality.
A team of scientists from the University of Colorado School of Medicine and the Charles C. Gates Center for Regenerative Medicine at CU Anschutz has reported a more efficient approach to reprogramming a patient's diseased skin cells into stem cells, raising hopes for future clinical trials and potential cures for critical illnesses.
