The human brain is the most complex and powerful computer in the world — and, as far as we know, the universe.

Today’s most sophisticated artificial intelligence (AI) algorithms are only just beginning to offer a partial simulation of a very limited number of the brain’s functions. AI is, however, much faster when it comes to certain operations like mathematics and language.

This means it comes as no surprise that a great deal of thought and research has gone into combining the two. The idea is to use AI to better understand the workings of the brain and eventually create more accurate simulations of it. One day, it may also help us to create systems with the complexity and diversity of… More.

Explore the thrilling convergence of AI and the human brain as cutting-edge technologies like Neuralink blur the lines between science fiction and reality.

The permission was given by California Public Utilities Commission after a 3–1 vote.

In a massive win for driverless cars in the United States, California has permitted Cruise and Waymo to conduct full-fledged commercial passenger service using driverless vehicles in San Francisco.

The permission granted by the California Public Utilities Commission (CPUC) allows both firms to charge fees for journeys at any time of day. The approval comes after a disputed six-hour hearing on the matter that included residents voicing their concerns about autonomous vehicles (AVs) roaming their roads. Hearing all the arguments, the commission voted 3-to-1 to allow the two businesses to run their cars across San Francisco at any time of the day.

Scientists have developed a way to recycle plastic waste by transforming it into soap.

For the first time, researchers have used plastics to create soap. To achieve this goal, a team led by Virginia Tech scientists devised a novel approach.

As per the official release, this innovative method allowed them to upcycle plastics into chemicals known as surfactants, which are widely used in making soap and detergent.

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.

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.

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.

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.

Chipotle restaurants have employees specifically dedicated to making guacamole, but it takes almost an hour to make one batch, and employees listed the task as one of the “less favorable” among other things they do at the restaurant.

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.
