Why can dogs understand human language

A new study shows that dogs can really understand human language. Even dogs handle the words they hear in a similar way to humans in the same area as the language processing area in the human brain.  This explains why people’s best friends are excited when we say “walking” or when we respond to them in a loving tone.

More than a dozen dogs are trained to stay still in a magnetic resonance scanner that helps scientists track how their brains work when toys are hung high above. When the team used the correct words to describe toys, or say nonsense words, different areas of the dogs’ brains lit up.

Neurology professor Gregory Berns of Emory University (USA) said: “Dogs can have different abilities and motivations to learn and understand human speech. They seem to show a nervous expression in front of the meaning of the words they have been taught, not just low-level reflexes like the reflexes discovered by Russian scientist Pavlov. ” .

Ashley Prichard, the first author of the study in Bern’s psychological lab, said: “Many dog ​​owners think their dogs know the meaning of some words, but there is not really much scientific evidence to prove it. And we want to get data from the dog itself, not just based on the owner’s judgment. ”

Researchers focus on problems around the dog’s brain mechanism when listening to a speaker, even when they hear only one word.  In the latest study, published in Frontiers in Neuroscience, owners of 12 other dogs trained their dogs for months with the aim of finding and bringing back two different objects when they called their names. objects.

To make it easier to distinguish, they chose the first item to be a stuffed animal, while the second was a hard toy made of rubber. After bringing these items back to the owner, the dogs will be rewarded with food or praised.

 

Absolute mistakes away from eating seafood

Seafood is a nutritious food, but experts recommend that eating seafood is also important because seafood is a respectable food but also a food that is harmful to the body.  Seafood is a food source that provides excellent vitamins and minerals for the body.

According to studies in the composition of seafood contains many natural minerals.  Most types of seafood contain unsaturated omega 3 oils that help circulate blood well, prevent the formation of thrombosis, reduce the risk of cardiovascular disease and stroke.

Therefore, eating a lot of seafood will not increase fat accumulation or gain weight because omega 3 is unsaturated fatty acid that helps minimize the amount of cholesterol loaded into the body of bodybuilders. Very rich in protein

For those who regularly practice or practice their hands, abdomen, thighs, it is especially important to add protein to the body. And in seafood protein content is very high. According to the study, about 150g of seafood (fish, shrimp, crab, clams, oysters …) will provide about 50-60% of daily protein needs. Besides, providing a reasonable and adequate amount of protein will help prevent edema, arrhythmias, fatigue, anemia …

Bacteria in seafood are mainly relatively hot bacteria, only temperatures above 80 degrees C can kill. In addition, seafood also contains many parasites and pathogens caused by processing. Therefore, seafood that needs boiling water can kill bacteria. When eating steamed crabs, marinated seafood, hygiene and freshness of seafood should be ensured.

The types of seafood hard shelled with many bacteria and fast protein resolution so when they die they produce more toxins and unsaturated fatty acids are also easily oxidized. So all kinds of hard-shelled seafood are not easy to cause acidic roots to threaten health.

Live seafood should not be stored in the refrigerator for too long, so it should be quickly processed. The number of people eating seafood is often mistaken as the susceptible reactions are not caused by seafood but by the processing of baked goods, the resolution of proteins in seafood.

The earth can be destroyed

The Earth can be destroyed, humanity can disappear, but life on this planet will always exist. We always find a path, which is the special and eternal thing of the so-called “life”.

You may find it hard to believe, but try looking back at Earth’s development history. At least the only living planet in the universe to date has experienced 5 mass extinctions, occurring in the Cretaceous, Triassic – Jurassic, Permian – Triat, Devon, and Ordovician – Silurian.

And even now, the planet is in the sixth mass extinction event – the Anthropocene Century. But the Earth will continue to be green. At the very least, it is green for the next billion years, though that eternity does not include humanity in it.

In fact, it is not too complicated to destroy life on Earth as we know it. There are 3 ways to do that. First, it is a meteorite. Our Earth has experienced this in the Cretaceous period. Suppose now there is also an asteroid flying into Earth’s orbit, what will happen?

Of course, it would descend at tremendous speed and crash into Earth, blowing up the earth’s crust. The amount of dust thrown into the air would be thick enough to block all the sunlight. Without warm sunshine, the whole Earth will freeze for a long time.

Second, it is a supernova – when a star dies and explodes – happens right next to the Earth. The heat from such an explosion could reach 1044J, enough to turn everything nearby into a sea of ​​fire.

And the last catastrophe is the gamma-ray burst – which is also a massive energy explosion, occurring at the same time as the supernova. It is also hot enough to ignite the ground, boil the ocean, destroy the ozone layer and create acid clouds that destroy our green planet.

Just as a planet in the solar system, the Earth of course is also capable of being hit by a planet with the same cardboard system. But please rest assured. Even if it was hit by an asteroid 1,000 times larger than the asteroid, it destroyed the dinosaurs in the Cretaceous era.

The US economic recession is inevitable

According to the majority of US economic analysts, the US economic recession is hard to avoid in 2019. In the survey conducted by Duke University, only 18% of the finance think that there will be no recession before 2020.

The second major theme of next year is economics. Nearly half (48.6%) of CFOs of major US corporations expressed concern that the recession will begin in the second half of 2019. At the end of 2018, a survey conducted by Duke University showed that the majority (82%) of corporate finance executives considered the recession inevitable, if not in 2019, it would be in 2020.

The first warning sign of the beginning of the ending the economic recovery cycle, taking place for nearly a decade, is the stock market indexes plummeted at the end of 2018. The meeting in 12/2018 by leaders of the agencies managing the Department US Federal Reserve (FED), has proved that Wall Street stock brokers are worried about it without cause.

In 2018, the basic discount rate has been raised (0.25%) for the fourth time, and in 2019, it is expected that there will be only two increases in the discount rate. This means that the US economy is currently not performing well, and it needs to be stimulated to accelerate by the support of “black” money” with low discount rate.

The decline in the growth rate, according to the evaluation of FED experts, relates a lot to the losses from the US-China trade war launched by Trump. The survey mentioned above by Duke University shows that the key financial leaders of 212 leading corporations are pessimistic about the prospect of profit in 2019, for their corporations.

If in 9/2018, the profit growth rate is 13%, then 2019 is expected to be only 4.5%. At the same time, it is also expected that a decline in income growth, investment growth and expansion of corporations, as well as a few other indicators that characterize the company’s operations.

Reporters shook because the German journalist admitted fabricating the news

The famous German news magazine Der Spiegel fired a prize-winning journalist after he was accused of fabricating details and quotes in many of his articles.

Guardian reported that the news magazine Der Spiegel had fallen into crisis after admitting that one of their top journalists had fabricated information in the past few years. This information has caused the world news so shock.

Accordingly, the journalist Claas Relotius is accused of “fabricating details on a large scale and even composing characters” in at least 14 of his 60 papers. They have appeared in print and electronic journals. Der Spiegel warned that other news agencies could be affected. Among the relevant articles are the important articles that have been nominated or won, Der Spiegel said.

In a statement released on December 19, the German magazine said it was determining the full scale of the rumors of Relotius. It was found after a colleague co-operated with the journalist in an article expressing the suspicion of Relotius’s post.

An investigation into Relotius’s article on migration and the US-Mexico border shows that he fabricated information about seeing a hand painted sign in a Minnesota town: “The Mexicans get out of here “.

The fabricated information appeared on other articles including an article about prisoners at the US military base in Guantanamo Bay and an article about American football player Colin Kaepernick.

Relotius, who started writing for Der Spiegel as a freelance journalist in 2011. He confessed to the magazine that he regretted his actions and was extremely embarrassed. Relotius wrote a total of 60 articles for Der Spiegel, many of which he claimed to be accurate.

Der Spiegel is one of the most prominent news agencies in Germany. It was founded in 1947 and is well known for its in-depth investigation papers. The magazine sells around 725,000 copies a month and attracts more than 6.5 million readers on the site.

 

The way for media newspapers developed in the time of technology

Information is the opportunity to re-establish the value of the mainstream press and focus on quality. Relying on readers is the longest, most stable and lasting way for a newspaper to grow.

Just a few decades ago, the press was still a reliable source of information at affordable prices. Readers did not hesitate to spend the amount of money as well as their breakfast to buy daily news.

At present, the technology platform is growing. The more online advertising and social networking appear to be as a news approach to information for people. The press is losing faith in its readers. On the other hand, it is struggling to find new ways of business before the development of technology.

The “read the newspaper” by social networking brings “single benefits but many benefits” such as diverse information, fast updates, news spread and almost free.

The Facebook Instant is an example. This feature allows users to read the full text of the articles right on their News Feed without opening a web browser. On average, Facebook users spend less than a second waiting to open a newsletter, which is 10 times faster than previous rates.

The social networking is the place to spread the news but not all the news are originated from here. In addition to famous technology companies such as Facebook or Google spread advertising, false information. But it is their media organizations who are responsible for messages in the first.

There are articles that are classified ads, but the title is not labeled and mixed with other news. The disguised ads that are also considered fake. Fairly speaking, the fake news is an opportunity to re-establish the value of the mainstream press brand and focus on quality.

In the face of overwhelming and overwhelming online information, news publishers need to focus on creating meaningful and influential articles that will convince readers to spend money for it.

Of course, these promising solutions or promises of journalistic quality can not change the field of journalism better overnight. But they can also improve media – advertising – news – beliefs.

 

Chinese scientists have created the world’s first genetically modified twins

Recently, in the news, a Chinese researcher has just claimed to have created the world’s first two genetically modified twins with new tools. Ha Kien Khue, a researcher in Shenzhen City, Guangdong Province, is well known. He confirmed that embryonic adjustments of seven couples and one of them resulted in successful DNA adjustment.

Mr. Xia said that the goal of the experiment was not to treat or to prevent genetic diseases. But it is tried to incorporate biological features. It is that few have such as the ability to resist HIV infection.

According to Chinese scientists, the couples who participated in the experiment did not accept identity claims or interviews with the news. He refused to disclose that where is about of the couples.

He recruited volunteer couples from an AIDS rights group that is called Baihualin. Genetic modification is performed during artificial insemination (IVF). Scientists began to wash sperm of men to separate from semen where contains the HIV virus. After transplanting sperm and eggs to create embryos, genetic modifiers are added.

After 3-5 days, they removed some cells from the embryo and checked the progress of gene regulation. Couples are choose between embryonic or non-regulated embryos for pregnancy. “16/22 embryos were adjusted and 11 embryos were used in 6 attempts to attach to the uterus before a pair of twin pregnancies”, Mr. Xia said that.

Initial screening results revealed that one of the twins was inherited from both copies which are modified gene. There are no signs that other genes was compromised.

The scientist said he had informed the volunteers of the mortality target and reminded the trial of risks. In addition,  he will support for artificial insemination which is completely free. He also pledged to provide insurance for all babies born in this experiment. He accepts medical support for children up to 18 years of age or more if they agreed.
