Nerve cell activity shows how confident we are — ScienceDaily

Should I or shouldn’t I? The activity of individual nerve cells in the brain tells us how confident we are in our decisions. This is shown by a recent study by researchers at the University of Bonn. The result is unexpected — the researchers were actually on the trail of a completely different evaluation mechanism. The results are published in the journal Current Biology.

You are sitting in a café and want to enjoy a piece of cake with your cappuccino. The Black Forest gateau is just too rich for you and is therefore quickly eliminated. Choosing between the carrot cake and the rhubarb crumble is much trickier: The warm weather favors the refreshingly fruity cake. Carrot cake, however, is one of your all-time favorites. So what to do?

Every day we have to make decisions, and we are much more confident about some of them than others. Researchers

Climate patterns linked in Amazon, North and South America, study shows

University of Arkansas researchers have established a link between climate patterns in the Amazon and large parts of North and South America using their newly developed tree-ring chronology from the Amazon River basin.


The discovery helps researchers better understand large-scale climate extremes and the impact of the El Niño phenomenon.

Tree growth is a well-established climate proxy. By comparing growth rings in Cedrela odorata trees found in the Rio Paru watershed of the eastern Amazon River with hundreds of similar chronologies in North and South America, scientists have shown an inverse relationship in tree growth, and therefore precipitation patterns, between the areas. Drought in the Amazon is correlated with wetness in the southwestern United States, Mexico and Patagonia, and vice versa.

The process is driven by the El Niño phenomenon, which influences surface-level winds along the equator, researchers said. El Niño is the name given to

Brad Parscale describes marital problems in back of police car, body camera footage shows

A drunken, tearful Brad Parscale sobs to a responding officer in the back of a police car and explains that he “couldn’t accept” that his wife won’t sleep with him in a newly released video.

“I just couldn’t accept she isn’t having sex with me. I couldn’t accept it,” Parscale, President Donald Trump’s former campaign manager, tells an officer as he sits in the back of a police car.

“She doesn’t?” the officer asks.

“No. Not in months. I just couldn’t accept it. I kept asking her,” Parscale says. “I’m filing for divorce tomorrow as soon as I get out of here. I’m gonna do this thing, whatever, and prove I’m not [expletive] crazy.”

The Daily Mail, the UK-based tabloid, obtained the police bodycam footage. In another video, an officer photographs bruises on Candice Parscale’s arms and a cut on her lip.

He asks her how she got the

Iranian government admission shows Trump right and Biden wrong on student visas | American Enterprise Institute

The Trump administration’s efforts to restrict student visas from countries designated as state sponsors of terrorism might seem like common sense, but, like everything else in an election year, it has become fodder for the partisan meatgrinder. Late last month, U.S. Immigration and Customs Enforcement published a rule change to end indefinite visas for enrolled students originating in countries where visitors often violated the terms of their visas, or countries that are state sponsors of terrorism. None of this, of course, would end the issuance of visas; rather, certain students would have to re-apply after two or four years.

Joe Biden has generally opposed any new controls on foreign students. “Across the world, people come to this country with unrelenting optimism and determination toward the future. They study here, innovate here, they make America who we are. Donald Trump doesn’t get that — we need a president who does,” Biden

Body Camera Footage Shows Detailed Aftermath of Breonna Taylor’s Killing

Body camera footage from the night Breonna Taylor was killed has been released by the Louisville Metro Police Department, CBS News reports. The footage raises questions about why Taylor’s home was targeted. 

More than 250 videos and over 4,000 pages of documents were released on Wednesday, one of which shows Taylor’s boyfriend, Kenneth Walker, outside the home after she had been shot telling the police that his partner had died. 

“Who else is in the apartment?” an officer asks Walker. “Nobody,” he replied. “My girlfriend’s dead.”

The SWAT team then enters the home and designates the residence a crime scene. One officer is then heard saying “We have to be mindful of what we say, we are on camera now.” After checking Taylor’s pulse, a member of the SWAT team can be heard saying “she’s done,” per TMZ. The outlet also points out that the graphic video shows “bloodstains on

Twitch Picked Up Most Of Mixer’s Streamers, Report Shows

KEY POINTS

  • Twitch’s share of hours broadcast on major live-streaming platforms saw the biggest increase after Mixer’s shutdown
  • This is despite Mixer’s attempt to funnel its streamers to Facebook Gaming
  • Twitch saw a decrease in viewership in the last quarter while YouTube and Facebook Gaming grew

Despite Microsoft’s efforts to push Mixers streamers to Facebook Gaming, it appears most of them went to Twitch instead, according to a new report.

Before Microsoft shut down Mixer in July, the company tried to direct its streamers and audience toward Facebook Gaming rather than the leading streaming platform. However, a report from Streamlabs & Stream Hatchet indicates that Twitch has become the ultimate beneficiary of Mixer’s closure. 

Twitch’s share of hours broadcast on major live-streaming platforms jumped by over 14.5% in the last quarter. This is nearly identical to the 14.2% market share that Mixer held at one point. The report stated that

World’s largest experiment shows shack fires move with devastating speed — ScienceDaily

Twenty shacks destroyed in five minutes. That’s how quickly fires can spread in informal settlements.

This is one of the major results of the world’s largest informal settlement fire experiment consisting of twenty homes.

The experiment was conducted by the Fire Engineering Research Unit at Stellenbosch University (FireSUN) in collaboration with the Western Cape Disaster Management, Fire & Rescue Services and the Breede Valley Municipality (BVM) Fire Department who hosted the experiment and provided significant assistance to the overall research efforts. The work forms part of a collaborative project with the University of Edinburgh looking at how to reduce the impact of such fires, which has been funded by the UK-based Global Challenges Research Fund.

The results of the experiment have been published recently in Fire Technology, one of the leading academic journals in fire safety.

[A video of the experiment can be watched at https://youtu.be/kkXr6ueakAU with the technical details
