Fish-shaped nanorobotics have been created to aid in the delivery of medicine in vivo

Chinese researchers have 3D-printed nanostructures with a sub-15 nm resolution using genetically engineered recombinant spider silk proteins, which are intended to be used in bionic perception and nanorobots for drug delivery and other applications in the future.

The nano fishes with barbels can “swim” in the human body’s glucose-containing environment, and certain parameters are set to inhibit the release of the medicine that the nanodevices contain.

The scientists took specific gene sequences from natural spider silks, the hardest fiber in nature, and then cultivated the portion in Escherichia coli to manufacture the proteins required to create such nano fishes.

According to Tao Hu, a researcher at the Chinese Academy of Sciences’ Shanghai Institute of Microsystem and Information Technology, the finest part of the nanorobotics, the barbel, is only 50 nanometers thick, or roughly one-thousandth the diameter of a human hair.

Biofuel-powered nanorobotics relies on adjusting enzyme activities and a sequence of chemical processes primarily involving glucose inside the human body to form oxygen bubbles in order to achieve directional motion control. Meanwhile, they can decay under specific conditions such as light, pH, and heat, causing no harm to the human body, according to the report. The work was published in the journal Nature Communications online.

This is a golden opportunity to cooperate with a government: President

President Dr. Mohamed Muizzu states this is a golden opportunity for a parliament that will cooperate with a government that wants to produce results.

Speaking at a meeting with Addu City constituents residing in Male’ City on Friday night, the President said his administration’s only focus is to produce results.

He described the upcoming parliament election as a golden opportunity for a parliament that will cooperate with a government that wants to produce results.

“My focus is on results, nothing else. It is results that the people want, is it not? The result of development and the result of stability, is that not what people have been wanting?” he questioned.

Speaking further, President Muizzu, underscoring the nation had not seen the desired number of changes in the past years, said his administration will not spend time on anything other than producing results.

“This is truly a golden opportunity. You are receiving a golden opportunity to pave the way for full cooperation necessary within the parliament to a government that is solely focused on producing results,” he said.

Citing the aforementioned reasons, he urged the public to vote for ruling PPM-PNC coalition’s candidates contesting in the parliamentary election slated for Sunday.

MDP has the largest number of candidates contesting this parliamentary election at 90 constituencies, followed by PPM-PNC coalition at 89 constituencies.

A total of 368 candidates are contesting for 93 constituencies.

Polling stations will be open from 8:00am to 5:30pm on Sunday; a decision made by the Elections Commission earlier today, which is undertaking final preparations for the election.

HELSINKI, April 19 (Xinhua) — European Commission President Ursula von der Leyen and Finnish Prime Minister Petteri Orpo on Friday urged de-escalation amid Iran-Israel tensions.

They made these comments at a press conference held at southeastern Finland’s Lappeenranta airport on Friday. The event followed a visit to the Finnish eastern border near the town of Imatra.

“We must do everything possible to ensure that all sides refrain from escalating the situation in the region,” said von der Leyen. She emphasized the necessity for stabilizing in the region.

Orpo expressed hope that both sides would avoid retaliatory attacks.

According to local media reports, the purpose of their visit to the eastern border was to inspect a pilot fence, about three kilometers long, built near the Imatra border crossing.

Blinken says U.S. not involved in Israeli attack against Iran

U.S. Secretary of State Antony Blinken said Friday that he can’t speak to media reports about the details of an Israeli attack against Iran overnight, stressing that the United States was not involved in any offensive operations by Israel.

“The reports that you’ve seen, I’m not going to speak to that, except to say that the United States has not been involved in any offensive operations,” Blinken told a press conference in Italy as he wrapped up a meeting with foreign ministers of the Group of Seven (G7) countries.

He was responding to a reporter’s question seeking confirmation of media reports saying Washington received advance warning from Israel on Thursday of an imminent strike against Iran in retaliation for Tehran’s assault on Israel last week.

“What we’re focused on, what the G7 is focused on, and again, it’s reflected in our statement and in our conversation, is our work to de-escalate tensions, to de-escalate from any potential conflict,” Blinken said in what were first public remarks on the Israeli attack by a cabinet member of U.S. President Joe Biden’s administration.

What Blinken also refused to address during that round of questions and answers was the White House’s assessment of whether the Israeli strikes were over and if Iran would retaliate.

Earlier on Friday, Iran’s air defense systems shot down several “flying objects” near the central city of Isfahan, according to the semi-official Fars news agency.

The Israeli side has not yet made any announcement regarding the attack.
