Japanese discovery promises to revolutionize Covid-19 detection

A PUB

A group of Japanese researchers have made a discovery that promises to revolutionize the detection of Covid-19. We are talking about the development of masks that glow when exposed to ultraviolet light when traces of the SARS-CoV-2 virus are detected.

According to scientists from Kyoto Provincial University, cited by Kyodo News, this innovation is possible using antibodies isolated from ostrich eggs – animals that, according to the same scientists, are capable of producing several different types of antibodies or proteins that neutralize unknown organisms in the body. …

“We can mass produce ostrich antibodies at a low cost. In the future, I want to turn this into a test kit that everyone can use, ”said Yasuhiro Tsukamoto, the team’s project leader.

Last February, the team injected an “inactivated form” of coronavirus inside an ostrich, a surgery that scientists say was a success as it ended up extracting large amounts of antibodies from ostrich eggs.

With this discovery, the team moved on to the next step: developing a special filter that fits inside the face masks, which can be removed and sprayed with a fluorescent dye containing antibodies from ostrich eggs.

When the researchers conducted a 10-day trial involving 32 volunteers infected with covid-19, they found that all participants’ masks glowed under ultraviolet light, which then faded over time as the viral load dropped.

The team of scientists now intends to expand the trials to 150 participants, awaiting government approval to sell the appropriate masks as early as next year.

Salma al-Shehab, a Saudi student at the University of Leeds, UK, was sentenced to 34 years in prison for having a Twitter account, following and distributing posts by dissidents and anti-Saudi activists when she returned home this summer. on holiday.

Initially, according to The Guardian, Salma was sentenced to three years in prison for the “crime” of using the website to “cause public disorder and destabilize civil and national security.” But on Monday, after a prosecutor’s request to consider other crimes, the court of second instance issued a new sentence: 34 years in prison, followed by a 34-year travel ban.

According to an English newspaper that had access to a translation of court records, the new allegations include an allegation that Shehab “helped those who seek to cause civil unrest and destabilize civil and national security by following his Twitter accounts” and sharing his tweets.

In a brief social media consultation for a 34-year-old Saudi mother of two, Shehab appears to have no activist profile, while on Instagram she reveals her more personal life, presenting herself as an oral hygienist and doctoral student. student. Twitter already has shares of Saudi dissidents living in exile asking for the release of political prisoners in the kingdom.

The Guardian on Twitter declined to comment on the case, clashing with journalist Stephanie Kirchgessner over the possible influence of Saudi billionaire Prince Alwaleed bin Talal, who owns more than 5% of the social network through Kingdom Holding.

The case comes just weeks after Joe Biden’s heavily criticized visit to Saudi Arabia, during which several activists confronted the President of the United States of America about various human rights violations by the regime of Prince Mohammed bin Salman.

North Korea launched two cruise missiles

Published

on

The Seoul Ministry of Defense said North Korea launched two cruise missiles on Wednesday, ending a month-long hiatus in Pyongyang’s record-breaking series of weapons tests this year.

“We discovered this morning that North Korea launched two cruise missiles towards the West Sea off the coast of Oncheon, South Pyongan Province,” a ministry spokesman told AFP. “US and South Korean military officials are looking into detailed specifications such as range.”

North Korea has not tested a cruise missile, which is not prohibited by UN sanctions against the country, since January, the Yonhap news agency reported. Pyongyang last tested weapons on July 10, when several rocket launchers were launched.

Since January, North Korea has conducted a series of sanctions-repressive tests, including the launch of a full-range ICBM for the first time since 2017. Officials in Washington and Seoul also warned that the isolated regime was preparing to carry out what would be its seventh nuclear test.

Earlier this week, the South Korean and US military began preliminary drills ahead of their annual Ulchi Freedom Shield (UFS) joint exercise. The drills infuriate Pyongyang, which sees them as a rehearsal for an invasion.

South Korea says it will not pursue nuclear deterrence

South Korea’s president said today that his government has no plans to interfere with nuclear deterrence after North Korea’s nuclear capabilities increase. Yoon Suk-yeol urged Pyongyang to resume negotiations and diplomacy aimed at trading the stages of North Korea’s denuclearization for economic benefits.

Yoon’s office said South Korea’s director of national security, Kim Seong-han, discussed the launch with other officials before Yoon spoke to reporters at a press conference and reaffirmed South Korea’s military readiness.

Yoon told reporters that South Korea does not want violent political change in North Korea and called for a return to negotiations for a lasting peace.

Yun’s proposal, namely large-scale assistance in the fields of food, medicine and health care, as well as in the modernization of the energy industry and port infrastructure, is reminiscent of previous proposals by South Korea that were rejected by North Korea, namely, accelerating the development of nuclear weapons and ballistic missiles, which North Korean leader Kim Jong-un regarded as the main guarantee of his survival.

Nevertheless, Yoon expressed hope for a “meaningful dialogue” with North Korea about his plan and emphasized that Seoul is ready to provide appropriate economic benefits at every stage of the denuclearization process if North Korea adopts a real roadmap to abandon its weapons program.
