Elon Musk, one of the most successful entrepreneurs around the world and CEO of Tesla, gave his support to the Presidental candidate Andrew Yang. Mr. Musk shared his opinion about Yang on Twitter when he answered a comment made by the Twitter handle @HardcoreHistory. Andrew Yang is known for being a Bitcoin (BTC) supporter.

Elon Musk Supports Andrew Yang

A few days ago, the American political commentator and podcaster Dan Carlin (with the handle @HardcoreHistory) shared a tweet of Andrew Yang. The presidential candidate wrote in this tweet that he does not expect to agree with everyone but he is open to different approaches to face different challenges and solve problems.
Elon Musk answered to Carlin’s comment saying that he supports Yang. Yang is a candidate that has many times shown support for Bitcoin and the cryptocurrency market. The Democratic candidate is also a proponent of a universal basic income and he accepts campaign donations in Bitcoin and other digital assets.

The political action committee (PAC) Humanity Forward Fund has also joined forces with Opennode to raise funds from individuals and firm and back Yang’s presidential campaign.

The main proposal he is currently doing is to implement a universal basic income for all Americans aged over 18. These citizens will receive $1,000 per month independently of their employment situation.
Yang has to also debate for the next debate scheduled for September 12 this year. He will have to discuss different proposals with other candidates, including Joe Biden, Bernie Sanders, Elizabeth Warren, Kamala Harris, Pete Buttigieg, Beto O’Rourke, Cory Booker and Amy Klobuchar.

Immediately after the tweet written by Elon Musk, Andrew Yang answered saying that his support “means a great deal.” He has also congratulated Musk for building the future.

As mentioned before, Elon Musk founded SpaceX and The Boring Company, co-founded Tesla, Neuralink, OpenAI and PayPal. Moreover, he has also been ranked 21st on the Forbes list of The World’s Most Powerful People.

In the United States, there are yet not clear regulations related to the cryptocurrency market and virtual currencies in general. There have been many companies that had issues to operate in the U.S. because they couldn’t deal with the local regulations.

Another presidential candidate that is in favour of digital assets and Bitcoin is John McAfee. Although he is not running with any of the traditional parties, he received a lot of attention due to the different proposals he made. 
A McDonald's worker has been fired after allegedly refusing to serve a paramedics wearing full uniform because staff "don't serve badges."

Sunstar paramedic Anthony Quinn said the fast food worker in Madeira Beach, Florida, refused to serve him and his colleague after telling both of them that "we don't serve your kind here."

Quinn discussed the incident in a post on Facebook. "I walk into McDonald's just to use the bathroom and an employee goes we don't accept officers in here," he wrote.

"I tell her I'm not an officer. She then says anyone with a badge. Then says it to my partner as he walks in to order food, says we don't serve your kind here.

"Just insane how people are," Quinn added.

Caspers, the company which runs the Madeira Beach McDonald's, apologized to the paramedic for the employee's actions and said they have since been fired.

"We are aware of the unfortunate incident that took place at one of our restaurants last night. We, like you, were upset and disappointed and took immediate action," a spokesperson told ABC Action News.

"The employee has been terminated. What occurred does not reflect the values of our brand, our franchise, or the love and admiration we have demonstrated consistently for our friends in law enforcement and first responders. We have reached out to offer our sincerest apology."

The company also confirmed to WTSP that the employee was "no longer with the organization."

Last year, two police officers claimed they were mocked and refused service while attempting to order food at a Burger King in Louisiana.

Two Assumption Parish sheriff's deputies wearing full uniform said workers jokingly told them they restaurant was completely out of food while they were trying to order through the drive-thru speaker.

"They sat there for an extended period of time before someone finally let them order," the department's public information officer, Lonny Cavalier, wrote in the Blue Lives Matter blog.

"[One officer] could hear them inside laughing, but no one would come to the window."

In a statement to WBRZ, Joe Clements of Crown Restaurants, who own the Burger King restaurant in question, said: "The actions of these team members do not reflect the values and beliefs of our organization, nor do they reflect the values and beliefs of the Burger King Brand.

"I have investigated the incident and have determined that certain team members refused service to multiple guests in our drive thru, including the two deputies, on that day. As a result, these individuals no longer work for our organization."

Math is famously divisive. Some people like to say they’re not “math people” if they have trouble with the subject (though, that might not actually be a healthy approach). Well, guess who have turned out to be math people? Honeybees!

Devoted readers may recall some past stories on this front. Almost exactly a year ago, we learned that bees can understand basic numbers, including the semi-abstract concept of zero. Then, in February, scientists said they’d discovered not only that bees can count, but that they can also do basic arithmetic.

Now the honeybee-math trilogy is complete. With a new study published in Proceedings of the Royal Society B, the same international team of researchers behind those discoveries has announced that bees are also capable of linking numerical symbols to actual quantities, and vice versa.

That means honeybees can equate a symbol like the numeral 2 to the actual, abstract numerical quantity of 2 “things,” regardless of what the things are

This has all come as a bit of a shock, since the insects have under a billion neurons in their brains. They’re also pretty different evolutionarily from us and the other animals who’ve displayed an aptitude for math: pigeons, African grey parrots, rhesus monkeys and chimpanzees. But clearly, backbones aren’t everything, and honeybees have what it takes to ‘get’ numbers like few other species so far can. Today’s find not only buffs up the bees’ reputation a little bit more, but also provides insights into how other species process and communicate the very concept of numbers.

Practice Makes Perfect

So, how do you train bees to recognize that a given symbol means a specific “numerosity,” or amount of something? Or that a specific numerosity corresponds to a given symbol? The same way you get humans to learn it at an early age: practice.

The researchers trained 20 honeybees and marked each insect with a colored dot to identify them. Then they monitored the bees for about two to four hours each. Half learned to associate symbols with a numerical amount, and the other half the opposite, associating amounts with symbols. (In all cases, an upside-down “T” stood in for 3, and an “N” for 2.)

To train them, the researchers put the bees through a Y-shaped maze. In the first chamber, the base of the Y, the bees saw the thing they were being trained on — the symbol, or the numerical amount — and they then had to choose which leg of the Y to go into, one being labeled with a correct answer and the other a wrong one. Correct answers were rewarded with yummy sucrose, and wrong ones with icky quinine. (And don’t feel bad for any slow learners. “If a bee made an incorrect choice and started to imbibe the quinine, it was allowed to … collect sucrose to maintain motivation.” Don’t want any unmotivated bees!)

After the training, the bees were tested on how well they learned the concepts, by choosing between numerosity options they’d never seen before to represent the numerical quanitity (using different colors, for example, or different shapes of different sizes). And, for the most part, no matter what tricks the researchers threw at them, the bees could handle it, reliably identifying the right number of things, or the right symbol, depending on their training.

“Bees in both groups demonstrated significant learning,” the authors write, “demonstrating that bees learnt the two [symbols] had corresponding matching quantities associated with them.” Good for you, honeybees!

One-Way Learning

But there was one thing the bees couldn’t handle: reversing their training. The group that learned that N means 2, for example, couldn’t figure out that 2 corresponded to N, and vice versa. “While independent groups of bees are able to learn the association in either direction with similar performances in training and tests, it seems the association itself is not reversible,” the authors write.

Which is kind of neat. Even the most math-phobic person is likely to have no trouble grasping the idea that if a symbol refers to a number of things, then the opposite is true as well — most school kids aren’t struggling with the very meaning of numbers, after all. But something in the way bees learned to understand these representations of numerosity kept them from making that connection.

Humans process numbers and symbols in different parts of their brains, so this finding suggests maybe honeybees do too, and just aren’t able to connect them as well. “Understanding how such apparently complex numerical skills are acquired by miniature brains will help enable our understanding of how mathematical and cultural thinking evolved in humans,” the authors write. “And possibly, other animals.”

As far as we know, humans are the only animals that have come up with math. But, it’s increasingly looking like we’re not the only ones who can do it.

More than two thirds (67 per cent) of children believe their generation will be worse off than their parents’, according to a YouGov survey for Britain’s biggest children’s charity.

The children, born around the turn of the millennium, blame lack of job opportunities, financial insecurity and rising house prices as the top three factors that will leave them with a bleaker future than their parents.

They believe they will be physically healthier than their parents’ generation, with just 15 per cent saying they would be less fit. However, almost seven in 10 (69 per cent) believe they will be less happy and have more mental health problems.

They blame social media for worsening mental health by increasing their exposure to unrealistically-high expectations of body image and lifestyles. Rising crime rates, declining youth clubs and services and growing social intolerance of  the young are also cited.

Almost two thirds (62 per cent) of the 1,030 16-24-year-olds polled by YouGov felt the Government cared more about older generations than their own.

Writing for today’s Telegraph, Javed Khan, Barnardo’s chief executive, warned of a looming mental health crisis with one in eight children affected - and called for urgent and sustained investment in mental health services from the £20 billion a year NHS funding settlement.
Study examined mental-health implications of high levels of screen time

Screen time — and social media in particular — is linked to an increase in depressive symptoms in teenagers, according to a new study by researchers at Montreal's Sainte-Justine Hospital.

The research team, led by Patricia Conrod, investigated the relationship between depression and exposure to different forms of screen time in adolescents over a four-year period.

"What we found over and over was that the effects of social media were much larger than any of the other effects for the other types of digital screen time," said Conrod, a professor of psychiatry at the University of Montreal.

The researchers studied the behaviour of over 3,800 young people from 2012 until 2018. They recruited adolescents from 31 Montreal schools and followed their behaviour from Grade 7 until Grade 11.

The teenagers self-reported the number of hours per week that they consumed social media (such as Facebook and Instagram), video games and television.

Conrod and her team found an increase in depressive symptoms when the adolescents were consuming social media and television.

The study was published on Monday in JAMA Pediatrics, a journal published by the American Medical Association.

Low self-esteem

The study found that of all the forms of screen time, consuming social media can be the most harmful.

Conrod and her colleague, Elroy Boers, found that the increased symptoms of depression are linked to being active on platforms such as Instagram, where teens are more likely to compare their lives to glitzy images in their feeds.

"It exposes young people to images that promote upward social comparison and makes them feel bad about themselves," said Conrod.

"These sort of echo chambers — these reinforcing spirals — also continually expose them to things that promote or reinforce their depression, and that's why it's particularly toxic for depression."

They also tested to see if the additional screen time was taking away from other activities that might decrease depressive symptoms, such as exercise, but found that was not the case.

'A good pastime'

The most surprising finding for Boers was that time spent playing video games was not contributing to depressive symptoms.

The study suggests the average gamer is not socially isolated, with more than 70 per cent of gamers playing with other people either online or in person.

"The findings surprised us," he said. "Video gaming makes one more happy. It's a good pastime."

Dr. Martin Gignac, chief of child and adolescent psychiatry at the Montreal Children's Hospital, said there has been an increase in the number of emergency-room visits at the hospital related to teens having suicidal thoughts and behaviour in recent years.

"I don't think that [social media] is the only reason, but it's one of the risk factors we should monitor," said Gignac, who was not involved with the study.

As online relationships supplant in-person communication, Gignac said it's important that young people learn when posting about their lives online is healthy, and when it can hurt.

He's hoping that schools expand programs teaching kids about healthy online activity, and that learning how to practise good "digital citizenship" eventually becomes a universal part of school curriculum.

Scant research

Boers said he was inspired to dig into examining the effects of screen time in adolescents because it's something that's very common among youth, but not something that's widely studied.

"I would almost compare it to smoking in the 1970s, where the very negative effects are still relatively unknown," said Boers.

Though depression can be debilitating at any age, when it is found in adolescents, it is also linked to substance use, lower self-esteem and poor interpersonal skills.

He said, on average, teens are spending six-to-seven hours in front of a digital screen per day.

"What we found is quite worrisome and needs further investigation," he said.

He and Conrod hope their research will be used by pediatricians and other health-care providers to help more effectively treat teens for depression.

According to a recent study in the Journal Science, planting a trillion trees at the global scale could be one of the most effective and efficient solutions to the climate change crisis. An initiative of planting trees globally could help in scrubbing a considerable portion of heat-trapping emissions from our atmosphere.

According to the scientists and researchers, a program at this vast level could contribute to removing around two-thirds of the carbon dioxide (CO2) emissions majorly caused by the industrial revolution and cutting of the trees at a huge scale.

The scientists worked hard in their research and used Google Earth mapping for getting to the conclusion that there is enough space on earth to plant even more than a trillion trees without disturbing the cities and farmlands. The study reveals that an area covered by the trees about the size of the United States could easily remove about 205 out of approximately 3 billion metric tons of carbon from our atmosphere.

According to Thomas Crowther, who is a climate change ecologist in Zurich endorsed the idea of planting a trillion trees by saying that “This is by far — by thousands of times — the cheapest climate change solution.” He further insisted that this step should be taken without any delay because it would have immediate results in eliminating the impending danger to the climate.

He further emphasized that “It’s certainly a monumental challenge, which is exactly the scale of the problem of climate change.”

Australia, Brazil, Canada, China, Russia, and the United States have enough room available for reforestation.

However, according to Crowther, although it is an effective solution but not enough to control the climate crisis. He emphasized on the need to stop burning coal, oil, and gas.

Deforestation is the biggest reason for rapid climate change globally. Acres of rainforests are being cut down every day in Amazon for making space for agriculture. Cutting those trees are doubling the heat-trapping gases. While planting new trees is the best solution, stopping the deforestation would bring immediate benefits.

According to Chris Field, a scientist at Stanford University environmental told AP that this study makes sense, but it is an uphill task and won’t be easy to execute this plan. “The question of whether it is feasible to restore this much forest is much more difficult,” Field said in an email.
A new study reveals evidence of a large number of mutations in important Komodo genes.

Komodo dragons are the largest lizards on the planet, with some adults measured at more than 350 pounds and longer than 10 feet. They detect their prey, including deer and water buffalo, from miles away with an exquisite sense of smell, and at close range, they race at terrifying speeds. Even a single bite can be enough to seal the prey’s fate, because a dragon’s saliva contains potent anticoagulants: Once the bleeding starts, it doesn’t stop.

But when Komodo dragons bite each other, which they do with some frequency, they do not bleed out the way their prey do. That suggests that at some point, they evolved a resistance to their own anticoagulants.

It’s one example of the odd batch of traits that have fascinated scientists, including Katherine Pollard, an epidemiologist and biostatistician at the University of California, San Francisco, as well as a researcher at the Gladstone Institutes. She wondered what the Komodo dragons’ genome would reveal about their biology and evolution.

In a paper published last week in Nature Ecology and Evolution, she and her colleagues present the lizards’ genome, revealing evidence of a large number of mutations in important Komodo genes. Their analysis offers insights into the dragons’ blood, senses and other unique aspects of their anatomy.

The group cobbled together a draft genome from two dragons living at Zoo Atlanta some years ago, and used tissue from a dragon in the Prague National Zoo to flesh it out. But more recently, Abigail Lind, a postdoctoral fellow in Dr. Pollard’s lab, focused on the process of interpreting the genome. Using algorithms that helped parse which parts of the sequence coded for proteins, Dr. Lind identified more than 18,000 genes. With the help of other lizard genomes, the researchers made predictions about the genes’ roles.

“We wanted to particularly look at different unique traits,” Dr. Pollard said. “The most obvious one is they are gigantic. But there are some other really cool things about them.”

To look for Komodo genes that had undergone concerted evolution, the researchers pinpointed about 200 with a particularly large number of mutations compared to related species. This pattern suggested that natural selection had favored alterations to those genes, honing them into a form that is specific to the dragons.

Many such changes were related to mitochondria, the cellular structures responsible for generating energy. That implied that the dragons may have modified mitochondria to support their sudden bursts of speed.

Others represented a family of sensory receptors that have blossomed in number in the dragons, perhaps linked to their uncanny sniffing abilities.

Still others encoded numerous proteins involved in blood clotting, suggesting that the dragons may have special genes that allow them to survive their own saliva.

Additional lab experiments would be required to test how the dragons’ proteins actually work and how their modifications may enable their special abilities. For instance, Dr. Pollard is interested in mixing dragon saliva and blood together in a dish to see what happens. That may take a while, however.

“They don’t really want to give up bodily fluids,” she said of the dragons, unless they are anesthetized.

Surprisingly, the researchers found no particular insights into the lizards’ giant size. There were no obvious changes to genes involved in development and growth, as you might expect if there had been positive selection encouraging their growth.

One alternate hypothesis is that enormous size may be an ancestral trait among lizards, and tiny lizards are a more recent development. Perhaps the Komodos are the normal ones, Dr. Pollard speculated, and everyone else, through the eons, has changed.
