Chemists develop new sustainable reaction for creating unique molecular building blocks
Polymers can be thought of like trains: Just as a train is composed of multiple cars, polymers are made up of multiple monomers, and the couplings between the train cars are similar to the chemical bonds that link monomers together. While polymers ha.....»»
Drop it like it"s hot: Space Rider model falls gracefully
Over the last four months, the Space Rider team has been running a drop-test campaign whereby a full-scale model of the future orbital laboratory is dropped from a helicopter to test and qualify the deployment of its parachutes, at Salto di Quirra in.....»»
Invisible laser beam detects what a MacBook user is typing
A whitehat hacker has demonstrated the use of an invisible laser beam to detect what a MacBook user is typing, from a distance, through a window, without being able to see the keyboard … more….....»»
Breakthrough in molecular control: New bioinspired double helix with switchable chirality
The deoxyribonucleic acid or DNA, the molecular system that carries the genetic information of living organisms, can transcribe and amplify information using its two helical strands. Creating such artificial molecular systems that match or surpass DN.....»»
Model suggests spewing metal nanorods into Mars" atmosphere could warm the planet by 30 K
A small team of engineers and geophysicists from Northwestern University, the University of Chicago, and the University of Central Florida has found, via modeling, that creating millions of metal nanorods from material on the Martian surface and then.....»»
Modeling Earth systems at a quintillion calculations per second
Climate models compute vast amounts of information about Earth's climate system—from small water droplets to large-scale weather patterns—to re-create past climate or predict future climate. Accurately re-creating how Earth's energy (measured in.....»»

Can quantum particles mimic gravitational waves?
When two black holes collide, space and time shake and energy spreads out like ripples in a pond. These gravitational waves, predicted by Einstein in 1916, were observed for the first time by the Laser Interferometer Gravitational-Wave Observatory (L.....»»

Polarization and wavelength routers based on diffractive neural network
The concept of deep diffractive neural networks (D2NN) was introduced by Professor Ozcan's research team in 2018. D2NN combines the principles of light diffraction with the functionalities of neural networks. It consists of a series of continuous dif.....»»
Experiment uses quantum techniques to stimulate photons, enhancing search for dark matter
Scientists cannot observe dark matter directly, so to "see" it, they look for signals that it has interacted with other matter by creating a visible photon. However, signals from dark matter are incredibly weak. If scientists can make a particle dete.....»»
