Notre Dame To Peer Into Quarterbacks’ Retinas With The HelmetCam [Technology]

At its first spring practice on Wednesday, the Fighting Irish coaching staff introduced the "HelmetCam," a tiny camera that attaches to a player's helmet — Notre Dame used it opposite potential starting quarterback Dayne Crist's throwing arm — and records his every glance and decision. Much like a brain, the HelmetCam does not have the stability to survive recurring hard hits to the head, so it probably won't find its way into the school's NBC contract for game days, but it will provide the coaching staff with special insight into where their quarterbacks look on a given play. It's a great idea for QB training and play development so far in advance of the regular season — and it should add new pressure to the four players vying to start behind center for the Irish.

Therapeutic nanoparticles targeted to radiation treated tumors

Radiation and chemotherapy are common partners in anticancer therapy for solid tumors, but too often, the combined side effects associated with each mode of therapy can limit how aggressively oncologists can treat their patients. Now, a team of investigators from Vanderbilt University and Washington University in St. Louis, has developed a nanoparticle that only targets irradiated tumors, offering the potential for reducing chemotherapy-associated toxicities and increasing the effectiveness of combination therapy.

Graphene mass production comes closer with bulk wet chemical exfoliation of graphite

There are already several technologies that potentially allow mass production of graphene sheets; several of them are processing graphene in solution by exfoliating graphite. The general problem with this approach is however that is has been so far impossible to regenerate the undisturbed graphene lattice which was present prior to oxidation as decarboxylation inevitable takes place in the reduction step. In new work, researchers have now demonstrated the first bulk wet chemical exfoliation of graphite in association with an in situ covalent functionalization of intermediately generated graphene. With this novel chemical method, it is now possible to achieve covalently bonded functionalities without mechanical or sonochemical treatment. The covalent functionalization also protects the single-layer graphene from reaggregation and substrate-induced doping.

Major advance in understanding how nanowires form

New insights into why and how nanowires take the form they do will have profound implications for the development of future electronic components. PhD student Peter Krogstrup from the Nano-Science Center at the University of Copenhagen is behind the sensational new theoretical model, which is developed in collaboration with researchers from CINAM-CNRS in Marseille.
