British scientists shocked!

It turned out that the ancient Celtic warriors fought with willow bark shields

Reading time 4 minutes

In Leicestershire, England, researchers discovered a 2300-year-old shield that was made from tree bark. This fossil is the only specimen of such a shield of the territory of Europe.

The shield dates back to 395–250 BC. Archaeologists say that the discovery drastically changed their ideas about weapons of the Iron Age and caused a heated discussion between experts.

“This is certainly an amazing object, one of the most iconic and world-important finds I have seen in all my work,” admitted Julia Farley, curator of British and European Iron Age collections in the British Museum.

In 2015, researchers from the University of Leicester Archaeological Service near the Soar River found a shield. According to Matt Beamish, the chief archaeologist of the study, objects from natural materials of this time are extremely rarely preserved, but the shield has survived in marshy soil. Maybe he was specially placed in a water-filled pit.

Matt Beamish added that shields from the bark of that period had never been found in the northern hemisphere before. It was assumed that the wood material was too flimsy for use in wars. However, the reconstruction of weapons from alder and willow proved that the 3 mm thick shield was light but reliable enough in the battles of that time. According to Beamish, contrary to researchers’ assumptions, such weapons were widespread in that period.

The weapon is made of green bark, which is reinforced from the inside with slats of the same material. The main part is surrounded by a rim of hazel and wicker willow. Matt Beamish noted that “this is a lost technology,” which was not known before. Apparently, this technique was used in many areas for the manufacture of products from the bark.

“It was important,” says Farley. According to her, the Battersea shield had a similar shape. It was extracted from the Thames in the middle of the 19th century and dates from the same period.

Farley argues that the visual world of the Iron Age is lost for us, since from the period 395-250 BC few artifacts left. She added that a new find for her is “a small window into that world.” For Farley, this awareness is “incredible and so exciting.”

The shield was donated to the British Museum. Farley hopes that the shield will be exhibited in the museum next year.

Garbage was at the bottom of the deepest point of the ocean

American explorer made a record dive into the Mariana Trench

Reading time 4 minutes

Victor Vescovo descended into the deepest point of the ocean. His bathyscaphe reached the bottom of the world famous Mariana Trench. The depth of immersion was 16 meters more than in the previous descent in 1960.

The American explorer reached the Challenger Deep, the deepest known point in the ocean, its depth is 11,000 meters.

 

What did the researcher discover?

Victor Vescovo, a retired naval officer, was stunned to find something similar to plastic in the deepest point of the ocean. At this time, he was in a machine specially designed to withstand tremendous pressure. After spending four hours under water, he remembered only rubbish. It was a plastic bag and candy wrappers.

Plastic waste in the ocean, according to UN estimates, reached 100 million tons.

For the last three weeks, Vescovo has dived four times into the Mariana Trench to collect various biological samples and forms of rocky soil. He is the third man who descended to the bottom of the Mariana Trench. The last who tried to do this was Canadian film director James Cameron in 2012, and before that, one of the US Navy lieutenants in the 1960s plunged into the hollow. Vescovo dive was the deepest in history.

The expedition was watched by Atlantic Productions, which collected material for a documentary for the Discovery Channel. Work under pressure, poor visibility and low water temperature made it difficult to shoot. Anthony Geffen, creative director of Atlantic Productions, said it was the hardest shot in his experience.

“Our team had to pioneer new camera systems that could be mounted on the submersible, operate at up to 10,000m below sea level and work with robotic landers with camera systems that would allow us to film Victor’s submersible on the bottom of the ocean. ”

After the completion of the expedition at the end of this year, the team plans to transfer the apparatus to scientific institutions. After, the researchers will be able to use the device in further work.

Wikipedia became unavailable in the Middle Kingdom

China blocks access to all language editions of the Internet Encyclopedia

Reading time 4 minutes

Now China blocks access to Wikipedia, although previously only Chinese-language online encyclopedia publications were censored. The blocking began last month, according to an online monitoring service that runs under the Tor project. Attempting to access any Wikipedia page from a country, regardless of language, produces a connection error.

In April, Wikipedia joined to thousands of websites blocked in China

A separate group on the control of censorship Greatfire.org reported that China has blocked access to Wikipedia since April 22. Local users of Chinese network platforms also confirm limited access to the site.

It is not clear why the Chinese government blocked sites. But observers suggest the restriction may be due to the upcoming 30th anniversary of the Tiananmen Square massacre (June 4, 1989). The government has banned all discussions on this event. The block may be temporary. A similar situation: in January, China, without informing, blocked, and then unlocked the Microsoft Bing search engine.

Over the years, the country selectively blocked some Wikipedia pages that criticized its communist government. However, in 2015, China began blocking access to Mandarin-language Wikipedia pages after the encyclopedia website switched to HTTPS encryption to protect users from unauthorized monitoring.

Last month, the Wikimedia Foundation confirmed the blocking and reported that Wikipedia is not available in China. In addition, Wikimedia added that it did not receive notification of government plans. Previously, only the Chinese version of the site was banned in the country.

In a statement, the foundation said: “In late April, the Wikimedia Foundation determined that Wikipedia was no longer accessible in China. After closely analysing our internal traffic reports, we can confirm that Wikipedia is currently blocked across all language versions.”

“With the expansion of this block, millions of readers and volunteer editors, writers, academics, and researchers within China cannot access this resource or share their knowledge and achievements with the world. When one country, region, or culture cannot join the global conversation on Wikipedia, the entire world is poorer, ” the group added.

The encyclopedia edited by the community is periodically blocked by authorities around the world.

In 2017, the site was blocked in Turkey, and this year it was periodically blocked in Venezuela.

 

Vaccination wrestlers are being driven from social networks

Instagram blocks hashtags against vaccination

Reading time 5 minutes

Instagram struggles with misinformation about vaccinations by blocking hashtags that show false posts on a controversial topic.

Anti-vaccination messages on social media are considered one of the reasons for the decline in vaccination rates in recent years, when an estimated 169 million children worldwide missed the first dose of measles vaccine between 2010 and 2017.

Instagram already bans obvious hashtags, through which antivaccination activists are spreading false information. Labels #vaccinescauseautism (vaccines causes autism), #vaccinescauseaids (vaccines entail AIDS) and #vaccinesarepoison (vaccine is poison) have been got under the block.  Now the policy of the social network is expanding hashtags, which may seem at first glance neutral and harmless.

Misleading reports of vaccination on social media are believed to be one of the reasons why vaccination rates have been declined in recent years

For example, the hashtag #vaccines1234 (vaccines 1234) does not contain anything alarming in its formulation, but if the platform finds that this hashtag is used in a number of messages to promote vaccine misinformation, it will be added to the block list. When a hashtag is blocked, users don’t get results when they search for it on the social network.

Instagram has not specified a limit on the number of times after which the hashtag will be blocked. Instead, the platform said it would ban the hashtag in case the content displayed on its page contained «a certain amount» of fake anti-vaccination information.

False statements, such as #vaccinescauseaids and #vaccinesarepoison has already been banned and do not show the search results in Instagram

Instagram has taken these measures after recent Facebook pleas. The company announced that it «is considering additional measures» to address anti-vaccination messages after concerns about a controversial topic that appears in the groups and on the Facebook pages.

At that time, the company recognized that the challenge was complex as it struggled to strike a balance between freedom of expression and the security of its users. Despite this, the social network said it will continue to fight the problem.

Last month health Minister Matt Hancock said he «can’t rule anything out» when was asked if unvaccinated children should be kept out of school. NHS England Executive Director Simon Stevens also described the vaccine’s abandonment as a «growing public health time bomb».

In addition to banning hashtags, Instagram is considering showing educational pop-up messages to people looking for vaccine-related hoaxes. The platform is already showing similar messages to people who are interested in information about drugs and self-harm.

Instagram plans to show educational pop-up messages to doubting people

In February, YouTube stopped showing ads on many popular channels that promote anti-vaccination conspiracy theories. He made this move after protests from firms who have discovered that their advertising works, along with the controversial video.

The world health organization (WHO) said that in 2019 anti-vaccination became the «top 10 global health threats».
