MIT scientists conceive of quantum rods for 3D screens

Posted by in categories: biotech/medical, nanotechnology, quantum physics, virtual reality

They use a process called DNA origami.

This is according to a press release by the institution published on Friday.


TV screens equipped with quantum rods have the ability to generate 3D images for virtual reality devices. Now, MIT engineers have conceived of a way to precisely assemble arrays of quantum rods in the devices using scaffolds made of folded DNA that allow depth and dimensionality to be added to virtual scenes.

ESA’s Gaia satellite spots ‘retired stars’ passing through young star-forming area

Posted by in categories: computing, physics, space

These waves can reach heights comparable to stacking three suns on top of each other.

Astronomers have discovered a strange star system with “monster” tidal waves breaking on one of its stars. Astrophysicists from the Center for Astrophysics | Harvard & Smithsonian (CfA) developed new computer models to better understand the impact of huge surface waves.

The new models reveal “titanic waves” created by the tides of a smaller companion star to be repeatedly crashing on the colossal star in the system. This phenomenon has never been detected on a star, making it a significant discovery.

Zap with Microwaves to Reverse Spin

Posted by in categories: energy, quantum physics

Irradiating a uniaxial magnetic system with a specific sequence of microwave pulses can induce in the system quantum oscillations that cause the material’s spins to flip back and forth.

To make higher-density magnetic data systems, researchers are looking to crystalline materials that have switchable magnetic orientations. But for some of these materials, switching the magnetization direction—for example from spin-up to spin-down—requires overcoming a large energy barrier. Now Seiji Miyashita at the University of Tokyo and Bernard Barbara of the Institut Néel, CNRS Grenoble, France, predict that experimentalists could reverse a material’s magnetization by applying to it a specific sequence of microwave or optical-frequency pulses [1]. The approach could find applications in quantum information storage.

To reverse the spin of a magnetic material, researchers can apply high temperatures or high magnetic fields to push the system over the potential energy barrier that separates its spin states. Another option is to induce resonant quantum tunneling to move electrons through the barrier. Miyashita and Barbara propose a further method that bypasses the constraints associated with the application of intense magnetic fields in these previous methods.

Chipotle’s New Robot Can Prep 25 Pounds of Avocados in Half the Time It Takes a Human

Posted by in category: robotics/AI

Last year, fast-casual restaurant chain Chipotle brought in a new employee: Chippy the chip-making robot. Chippy was tasked with slicing corn tortillas into triangles, frying them, tossing them with lime juice and salt, and dividing them into portions. The bot must have done a pretty good job, because now the restaurant is bringing in one of its cousins: an avocado-prepping robot called Autocado.

Turning avocados into guacamole can be a tedious process. You have to slice the fruit open, remove its thin peel, and take out its pit. Then there’s the mashing and mixing in of other ingredients. Pretty doable for a batch of guac for two to four people, but less so when you up the final consumer count to, oh, 750,000 per day.

An Overview of Selected Bacterial Infections in Cancer, Their Virulence Factors, and Some Aspects of Infection Management

Posted by in category: biotech/medical

In cancer development and its clinical course, bacteria can be involved in etiology and secondary infection. Regarding etiology, various epidemiological studies have revealed that Helicobacter pylori can directly impact gastric carcinogenesis. The Helicobacter pylori-associated virulence factor cytotoxin-associated gene A perhaps plays an important role through different mechanisms such as aberrant DNA methylation, activation of nuclear factor kappa B, and modulation of the Wnt/β-catenin signaling pathway. Many other bacteria, including Salmonella and Pseudomonas, can also affect Wnt/β-catenin signaling. Although Helicobacter pylori is involved in both gastric adenocarcinoma and mucosa-associated lymphoid tissue lymphoma, its role in the latter disease is more complicated.

Chandrayaan-3 vs Russia’s Luna-25; Race to Moon’s south pole position

Posted by in category: space travel

Russia successfully launched its inaugural moon-landing spacecraft on Friday in 47 years. The mission aims to achieve the distinction of being the first country to achieve a gentle landing on the lunar south pole, an area thought to contain valuable reservoirs of water ice.

As per a report by Reuters, Russia’s recent lunar mission, it’s inaugural one since 1976, is in a competitive race with India, which sent its Chandrayaan-3 lunar lander to space last month.

Moreover, it’s part of a larger competition involving the United States and China, both of whom have well-developed lunar exploration initiatives that focus on the southern region of the Moon.

New Theory Suggests Quantum Entanglement And Wormholes Are Linked Together

Posted by in categories: computing, cosmology, particle physics, quantum physics

Practical applications for quantum entanglement have already been proposed, as entangled particles have been suggest for use in powerful quantum computers and “impossible” to crack networks. Now, it seems quantum entanglement may be linked to wormholes.
