China removes a restriction on foreign investment | World economy

China has removed a major restriction on foreign investment in the financial sector, a measure long demanded by the United States, with which it is waging a trade war.




China restrictions on foreign investmentForeign banks will now be able to establish branches in China and hold all the capital without necessarily associating with a local partner, according to the banking regulatory authority (CBIRC).

Until now, foreign banks were required to associate with a local partner and were not allowed to own more than 49% of the joint-venture in which they had invested.

This announcement sounds like a gesture of goodwill from China to the United States, at a time when a preliminary trade agreement between the two powers is expected to be signed later in January, according to Washington.

The first two economies have been fighting a trade war since March 2018 that has resulted in mutual fees of hundreds of billions of dollars in bilateral trade.

Beijing has long promised to open its economy further t…

Stunning photos of the “ring of fire” that was observed in Asia, the last eclipse of the year

From Saudi Arabia to Oman, through India and Southeast Asia, numerous astronomy lovers could enjoy the unusual perspective of the Moon and the Sun
The "ring of fire" observed from Tamil Nadu, in southern India

An annular eclipse of these characteristics occurs when the moon is not close enough to the Earth to completely cover the sun, revealing a thin solar ring.



These eclipses occur every one or two years and can only be seen from a narrow strip of the planet. View from Balut Island, Philippines.

This year, it was observed, when the weather conditions allowed, in the Middle East, in South India and in Southeast Asia, to the North Pacific.



"For the next one, we will have to wait about 40 years," said Jason Teng, 37, who took a day off at work to photograph the eclipse. The astronomer apprentice used a special sunscreen for his telescope, since it is dangerous for the eyes…

SpaceX wants to send three tourists to the ISS

The US space company SpaceX wants to send three tourists to the International Space Station ISS.



It is planned that the tourists will travel to the ISS in the second half of 2021 together with a commander in the "Crew Dragon" space capsule, as the Texas start-up Axiom - SpaceX's partner company in the project - announced on Thursday.Neither of the two companies gave any indication of how much the tourists would probably have to pay for the trip. 

The costs for the launch of the Falcon 9 rocket alone, which will transport the space capsule into space, amount to around 60 million dollars (53 million euros).

In addition, the construction of a new "Crew Dragon" capsule must be financed.

🔹 In this respect, the ticket for the flight should cost tens of millions of dollars.

In earlier years, a total of eight tourists had already travelled to the ISS in Russian Soyuz capsules. 

The first was US entrepreneur Dennis Tito in 2001, who paid 20 million dollars for a vacati…

A new species of insect was named after Lady Gaga for being eccentric. | Kaikaia gaga

Insect was named after Lady GagaBrendan Morris, PhD at the University of Illinois, observed the behavior of about a thousand treehoppers for his research project when he suddenly noticed one female who was different from the others.


Scientists decided to name the recently discovered insect in honor of Lady Gaga for their "eccentric sense of style," NME reports.

In the scientific publication Zootaxa, he and his co-author, the entomologist Christopher Dietrich, wrote about it "an additional cross m-cu (between the fourth and fifth longitudinal veins) in the front wing, as well as a frontal-clipella form".

Morris decided to call the insect "Kaikaia gaga" so that specialists could understand what kind of species we are talking about.

"If there ever is a Lady Gaga bug, it will definitely be a treehopper bug because of its crazy horns and eccentric sense of style. They don't look like anything you've seen before," he explained.

Now Morris hopes…

Scientists propose to fight viruses with fullerenes

Fight viruses with fullerenes
Scientists from Skoltech and the Institute of Problems of Chemical Physics of the Russian Academy of Sciences have created water-soluble fullerene compounds that have valuable biological properties. The results of the study are published in the journal Chemical Communications. Thanks to this biological properties they can be used to develop effective antiviral drugs, including to suppress the human immunodeficiency virus (HIV).

Fullerenes are molecular compounds composed of three-coordinated carbon atoms, which are closed convex polyhedra. Depending on the number of atoms in the molecule, fullerenes resemble a soccer ball (C 60 ) or a rugby ball (C 70 ) in shape.

Compounds based on fullerenes have a pronounced antiviral, antibacterial, antitumor and antioxidant activity, so scientists have long viewed them as a promising basis for the creation of new drugs. Unfortunately, fullerenes are absolutely insoluble in water, which prevents their use in medicine.

Medications have positive results in research for the treatment of coronavirus; here are 4 possibilities

Medicine used against malaria for almost 100 years and others without approval in Brazil are among the most promising after tests.


Four drugs showed positive - but still preliminary - results in scientific research in the treatment of Covid-19, a disease caused by the new coronavirus. These drugs act at different stages of cell contamination. They are:

ChloroquineRemindLopinavir/RitonavirFavipiravirHowever, self-medication is not recommended, since research has not been fully completed and it is not yet known whether there are any side effects from use by patients infected with the coronavirus.
The study on Favipiravir was released on Wednesday (18) - it is sold commercially in Japan under the name Avigan. It was developed by Toyama Chemical, of the Fujifilm group, and has been used for over 5 years against Influenza. Its use is only authorized in Japan.
The medicine is being tested only in laboratories outside the country. When consulted, Anvisa informed that there is no request for re…

What do dolphins and whales drink if there's only salt water around?

Have you ever wondered how dolphins and other marine mammals obtain fresh water when they have been in salty environments all their lives? 

They don't have a desalination unit like in the gills of marine fish, and their kidneys can't dissolve sedimentary minerals. What kind of trick did nature invent?They can't drink seawater: with dolphins and whales, nature played an evil joke. It would seem that they are surrounded by water, but the use of salt water, on the contrary, will lead to dehydration and death.
In the case of sea fish, part of the salt that comes with sea water into the body is desalinated in the gills, and the salty surpluses come out with urine.
The salty environment in which they live, constantly pulls moisture out of the fish through the skin. It's a natural process - osmosis.

Therefore, these sea creatures have to drink sea water all the time and the more salt they have in them, the more they have to drink.
Dolphins and whales can't do that. They have n…

Scientists at the IrsiCaixa AIDS Research Institute have confirmed that the so-called London patient has been cured of HIV, the second in the world, because 29 months after undergoing a stem cell transplant and stopping taking antiretrovirals he is still without a trace of the virus.The study of the London patient, published this Tuesday in the magazine "The Lancet HIV", has coincided with the announcement of another patient, in this case from Düsseldorf (Germany), which, according to the scientists, could become the third case in history to be cured of HIV, after the London case and one in Berlin.

New online today—30 month follow-up of the London patient, providing further evidence that he is the second person to be cured of #HIV. The long-term follow-up provides insi…
