Empa has developed an innovative, electrohydraulically actuated valve train for internal combustion engines, that enables completely free adjustment of stroke and timing, while at the same time being robust and cost effective. This valve train was mounted on a serial production engine and has been running successfully for several months. The new technology saves up to 20% fuel.
Lithium fluoride crystals have recently been used to register the tracks of nuclear particles. Physicists from the Institute of Nuclear Physics of the Polish Academy of Sciences in Cracow have just demonstrated that these crystals are also ideal for detecting tracks of high-energy ions of elements even as heavy as iron.
Harvard researchers have developed a new DNA-nanotechnology-based approach called Immuno-SABER, that combines the protein targeting specificity of commonly available antibodies with a DNA-based signal-amplification strategy that enables the highly multiplexed visualization of many proteins in the same sample with pre-programmable and tunable fluorescence signals at each target site.
EPFL scientists are investigating new ways to provide visual signals to the blind by directly stimulating the optic nerve. Their preliminary study uses a new type of neural electrode and provides distinct signals.
Inspired by Wall Street financial theories used to invest in the stock market, MIT and Microsoft researchers developed a 'risk-aware' model that improves the performance of cloud-computing infrastructure used across the globe.
A Nature Communications paper by Worcester Polytechnic Institute biologist Jagan Srinivasan has shown that a key biological component in the communication system of the nematode C. Elegans can be repurposed to take on a different job,. This critical finding about the workings of evolution could one day affect research into drug interactions, agricultural bio-engineering, and a better understanding of genetic inheritance through multiple generations.
According to Adar Ovadya, a master's student in BGU's Department of Software and Information Systems Engineering, 'all of the routers we surveyed regardless of brand or price point were vulnerable to at least some cross-network communication once we used specially crafted network packets. A hardware-based solution seems to be the safest approach to guaranteeing isolation between secure and non-secure network devices.'
A collaborative team at the Wyss Institute, Harvard SEAS, and the University of Nebraska Omaha reports in Science that they now have developed the first portable exosuit that can assist the extension of the hip joint during both walking and running. The team successfully tested their wearable robot in uneven outdoor environments while wearers walked uphill, and walked and ran at different speeds.
Researchers developed a drug delivery system that can break through the blood-brain barrier in mice.
The All of Us Research Program at the National Institutes of Health has made strong progress in its efforts to advance precision medicine, according to a paper in the New England Journal of Medicine. With information provided by volunteers across the United States, All of Us is developing a robust data platform to support a wide range of health studies. The program aims to include data from 1 million or more people from diverse communities.
