From nanoscale silver to titanium dioxide for air purification, the use of nanomaterials of high commercial relevance proves to have clear benefits as it attracts investments, and raises concerns. ‘Nano’ sized materials (a nanometer is one millionth of a millimeter) could pose environmental and health risks under certain conditions. The Read More
An illustration of the new IBN nanocomposite material which is composed of gold-copper alloy atoms in the core and platinum atoms at the outer layer.
Scientists at the Institute of Bioengineering and Nanotechnology have developed a more powerful and longer lasting fuel cell material by replacing the central part of the Read More
A team of researchers has devised a way to rapidly test different nanoparticles to see where they go in the body, helping identify particles for gene delivery or RNA interference.
Many scientists are pursuing ways to treat disease by delivering DNA or RNA that can turn a gene on or off. Read More
New data from the University of Liverpool reveals that the Earth’s inner core was formed 1 – 1.5 billion years ago as it “froze” from the surrounding molten iron outer core.
The inner core is Earth’s deepest layer. It is a ball of solid iron just larger than Pluto which is Read More
Many telescopes are formed of multiple mirrors or antennas, not just one. ESO’s Very Large Telescope (VLT), located at ESO’s Paranal Observatory in Chi vending telemetry le, is a prime example. The VLT comprises four main telescopes, and four smaller, movable auxiliary telescopes — eight individual structures in total. However, Read More
A polyethylene glycol-hydrophilic carbon cluster developed at Rice University has the potential to quench the overexpression of damaging superoxides through the catalytic turnover of reactive oxygen species that can harm biological functions.
A new Rice-led study revealscredit card vending machine how nanoparticles can quickly neutralize superoxides that are overexpressed by the Read More
MIT Media Lab researchers have developed a machine-learning model that takes computers a step closer to interpreting our emotions as naturally as humans do. The model better captures subtle facial expression variations to better gauge moods. By using extra training data, the model can also be adapted to an entirely Read More
Der Gründer der Enthüllungsplattform Wikileaks, Julian Assange, hat in Ecuador eine Klage gegen die dortige RegL2TP Industrie Routerierung eingereicht. Das teilte Wikileaks am Freitag per Kurznachrichtendienst Twitter mit. Assange wirft dem südamerikanischen Land vor, ihn in seinem Botschaftsexil in London in seinen Grundrechten zu verletzten.
Assange sitzt seit 2012 in der Read More
The oldest samples are sedimentary rocks that formed 3.2 billion years ago in northwestern Australia. They contain chemical evidence for nitrogen fixation by microbes.
New research from the University of Washington found evidence that life was pulling nitrogen out of the air and converbest industrial wifi routerting it into a form Read More
