The energy-storage goal of a polymer dielectric material with high energy density, high power density and excellent charge-discharge efficiency for electric and hybrid vehicle use has been achieved by a team of Penn State materials scientists. The key is a unique three-dimensional sandwich-like structure that protects the dense electric field in the polymer/ceramic composite from [...]
From nanowerk.com: Localization of photons to nanoscale volumes with the aid of plasmonic nanoantennas opened new horizons in bio(chemical) sensing and nanoscale imaging. However, plasmon resonances are short-lived, and the photon energy quickly dissipates as heat, creating temperature gradients on plasmonic chips. While being useful for solar vapor generation, cancer treatment and catalysis, localized heating [...]
From an interview conducted by April Cashin-Garbutt, MA (Cantab) at news-medical.net: Q: Can you please outline your latest research where you triggered the apoptosis ‘switch’ on in cancer cells forcing them to commit ‘suicide’? A: Before I explain the discovery, I would take a step back and explain an interesting event that takes place in the [...]
Written by Bill Gates - from gatesnotes.com: At some point today, you’ll probably do one or all of these things: Flip a switch for light. Take fresh food from a refrigerator. Turn a dial to make your home warmer or cooler. Press a button on your laptop to go online. You [...]
From Yahoo - Space.com (contributor) Crystals of proteins that could be useful in medical research can be grown bigger and better in space than on Earth, according to the results of experiments performed on the International Space Station. Medical research often focuses on examining how proteins work. That can include learning how to use proteins [...]
From phys.org: Imagine an electronic newspaper that you could roll up and spill your coffee on, even as it updated itself before your eyes. It's an example of the technological revolution that has been waiting to happen, except for one major problem that, until now, scientists have not been able to resolve. Researchers at McMaster [...]
From phys.org: A recent study by researchers at the Atlanta Veterans Affairs Medical Center took them to a not-so-likely destination: local farmers markets. They went in search of fresh ginger root. Back at the lab, the scientists turned the ginger into what they are calling GDNPs, or ginger-derived nanoparticles. The process started simply enough, with [...]
From Nanowerk News: Researchers at the Faculty of Physics at the University of Warsaw, using the liquid crystal elastomer technology, originally developed in the LENS Institute in Florence, demonstrated a bioinspired micro-robot capable of mimicking caterpillar gaits in natural scale (Advanced Optical Materials, "Light-Driven Soft Robot Mimics Caterpillar Locomotion in Natural Scale"). The 15-millimeter long soft [...]
From Kurzweil.net: Researchers from Polytechnique Montréal, Université de Montréal, and McGill University have designed a new cancer-drug-delivery nanotransporter system using more than 100 million flagellated, self-propelled bacteria that are capable of navigating through the bloodstream to administer a drug to tumors with precision.* The goal of the research is to avoid jeopardizing the integrity of organs and [...]
From Nanowerk News: A new ultra-high resolution "nanoscope" is capable of taking 3-D images of an entire cell and its cellular constituents in unprecedented detail, an advance that could reveal biological phenomena never before seen and bring new medical insights.The work (Cell, "Ultra-High Resolution 3D Imaging of Whole Cells") was carried out [...]
