Passengers travelling on a Spanish train were alarmed as their train momentarily stopped and wildfires could be seen on both sides of the track.
The footage was captured in the Spanish province of Zamora.
A spokesperson from rail operator Adif told the Associated Press that the passengers were never in danger.
A space elevator, a technology connecting the Earth’s surface to a space station, would allow for the cost-efficient transport of people and materials. However, a very light yet strong material is essential to making such a technology a reality.
The carbon nanotube is a material that is 100 times stronger, yet four times lighter, than steel, with copper-like high electrical conductivity and diamond-like thermal conductivity. However, previous carbon nanotube fibers were not ideal for extensive use, owing to the small contact area with adjacent carbon nanotubes and limited length they possessed.

The future is now as IBM unveils its comprehensive strategy to take quantum computing from noisy to useful. property= description.
Implications of the existence of a ‘conscious’ quantum particle.
I know this story is going to be weird in many ways but this is something worth thinking about. Theoretical physicist Richard Feynman once stated.
“Imagine how much harder physics would be if electrons had feelings.”
Remnants from the space rock may help explain how often these cosmic explosions occur—and the threat they pose to Earth.
If you had to describe Rich Uncle Pennybags—the Monopoly mascot—would you mention his top hat? His mustache? How about his monocle?
The face of the famous board game has, in reality, never worn a monocle. Yet, many people confidently list the accessory when recalling his features—an example of a phenomenon of false visual memories.
A forthcoming paper by University of Chicago scholars, currently available in preprint, found that people have consistent, confident, and widespread false memories of famous icons—also known as the Visual Mandela Effect. Co-authored by University of Chicago scholars, the paper is the first scientific study of the internet phenomenon.
The LHCb detector was originally designed to study a particle known as the beauty quark. But now researchers are also using the experiment to search for dark matter:
Researching subatomic particles is an involved process. It can take hundreds—if not thousands—of scientists and engineers to build an experiment, keep it up and running, and analyze the enormous amounts of data it collects. That means physicists are always on the lookout for ways to do more for free: to squeeze out as much physics as possible with the machinery that already exists. And that’s exactly what a handful of physicists have set out to do with the LHCb experiment at CERN.
The LHCb detector was originally designed to study a particle known as the beauty quark. “But as time has gone on, people have seen just how much more we can do with the detector,” says Daniel Johnson, an LHCb collaborator based at MIT.
Johnson, along with a team of around 10 researchers from MIT, the University of Cincinnati and CERN, are leading LHCb’s search for dark matter, a hypothesized type of matter that, so far, has evaded detection.
How can the “root causes” of outliers be identified once they are detected? At ICML, Amazon scientists address this in their paper, “Causal structure-based root… See more.
Amazon ICML paper proposes information-theoretic measurement of quantitative causal contribution.
Brain-computer interfaces have become a practical (if limited) reality in the US. Synchron says it has become the first in the country to implant a BCI in a human patient. Doctors in New York’s Mount Sinai West implanted the company’s Stentrode in the motor cortex of a participant in Synchron’s COMMAND trial, which aims to gauge the usefulness and safety of BCIs for providing hands-free device control to people with severe paralysis. Ideally, technology like Stentrode will offer independence to people who want to email, text and otherwise handle digital tasks that others take for granted.
Surgeons installed the implant using an endovascular procedure that avoids the intrusiveness of open-brain surgery by going through the jugular vein. The operation went “extremely well” and let the patient return home 48 hours later, according to Synchron. An ongoing Australian trial has also proven successful so far, with four patients still safe a year after receiving their implants.
It may take a long time before doctors can offer Synchron’s BCIs to patients. The company received FDA approval for human trials in July 2021, and it’s still expanding the COMMAND trial as of this writing. Still, the US procedure represents a significant step toward greater autonomy for people with paralysis. It also represents a competitive victory — Elon Musk’s Neuralink has yet to receive FDA permission for its own implant.
