THE ‘SMILING SUN’ RAISES CONCERNS

Thanks to technological progress, we are able to get sharper images of space. Sometimes, however, new discoveries can put scientists on alert. Such is the case with the recent image of the “smiling sun”.

In the photograph, the sun appeared to have some sort of eyes and a smile. It quickly went viral on Twitter, with users even making memes about it. However, experts did not find the photo so cute.

The “face” seen in the images, captured with several telescopes and 13 different wavelengths of light, is due to one of the hundreds of explosions occurring inside it. And while these explosions are normal, scientists at NASA’s Solar Dynamics Observatory (SDO) warned that the smile could be a sign of something dangerous.

WHY DO YOU SEE THESE HOLES IN THE SUN?

The dark spots seen on the sun are so-called “coronal holes”, which are slightly cooler areas of the sun’s outer layer. These usually have a temperature of about 10,000 degrees Fahrenheit.

Although they are not that cold compared to the rest of the surface, they are dark enough to only be captured in ultraviolet radiation. That is, the human eye can’t see them, and NASA’s satellite picks them up as these black spots.

Coronal holes are areas of high magnetic field activity, and they are always sending out solar wind into the Universe. The solar wind is nothing more than a stream of protons, electrons and other particles xxx porno.
Since the sun is practically a nuclear reactor, it never stops working. For example, there are thunderstorms, solar earthquakes and the conversion of hydrogen to helium, which sends out as much heat as several nuclear bombs.

 

WHAT IS THE THREAT POSED BY CORONAL HOLES?

As mentioned above, solar winds can escape from coronal holes and head out into the Universe. They can reach a speed of almost 3 million kilometres per hour, which in turn causes geomagnetic storms.

These storms can create currents in the electrical grids of planet Earth that can be dangerous because they send out particles that can cause serious disruptions in the atmosphere if they reach the Earth in large quantities.

These particles could be absorbed by our planet’s magnetic field, disrupting our communication systems, such as radio and TV antennas, GPS systems, as well as damaging power grids and causing power outages, loss of mobile phone signals and more.

The Earth already experienced a geomagnetic storm in 1959 when the so-called “Carrington Event” caused several fires at telegraph stations. Scientists have calculated the probability of such an event to be about 2% per year, but so far it has not happened.

However, because of this, it is possible that when it does happen, it could be catastrophic, especially given our high dependence on technology.

CREATE A SYNTHETIC EMBRYO WITH A BRAIN

Science advances at an incredible speed. Over the years, each technological advance has come closer to what we considered and wrote in fantasy novels as fiction. On this occasion, the contributions are in the field of medicine, and in the future imply countless benefits for future critically ill patients.

The discovery is said in few words, but it involves a long history of research, trial and error: it was possible to create an embryo that was functional until now, with a partially operative brain and heart, completely artificially.

The research took place at Israel’s Weizmann Institute of Science, using synthetic materials to create a real rat embryo. According to the researchers in charge of the project, this first step represents a giant discovery, since the embryo is the main natural factory of organs.

A much more efficient tool than 3D printers.

 

HOW DID YOU MAKE IT POSSIBLE?

As we say: easy to say, but the road was long and full of problems.
The investigation, so far, has been operational for at least ten years. Throughout this time, they sought to imitate the natural process of mouse stem cells in laboratory dishes, using a special machine that simulates the mouse uterus.

Unlike similar studies in the past, the Weizmann Institute of Science synthetic embryo now has a beating heart and a developing brain. Although it is not yet properly formed, it is currently in the phase of division by regions and solidification.

One of the points that caught the attention of scientists and filled them with high expectations with this specimen is the formation of the neural tube of the embryo’s brain, a key piece of the nervous system, in addition to a primitive formation of the intestinal tract.

If the project progresses as expected, we could be facing a new alternative to fight against malformations and genetic alterations. Likewise, the possibilities are opened for an immense number of patients who have been waiting for organ transplants that never arrive.

 

THE PROBLEM WITH STEM CELLS

Until now, although science had progressively advanced, it had not been possible to match the reproductive and creative power of stem cells, which are especially difficult to produce and much more difficult to control.

To make it possible, the researchers at the Weizmann Institute of Science took two previous advances from their team as a reference.

The first of them, a protocol for the reprogramming of stem cells in their earliest phase tukif; and the second, a device designed to simulate the uterus and promote the development of the artificial embryo.

THE PROBLEM WITH STEM CELLS

The device was made possible after seven years of tireless research, with numerous bugs and prototype failures along the way. In its most modern version, the “Ex Utero” consists of beakers that are kept loaded with embryos with nutrient solution. Each of these vessels is kept in constant motion, to simulate the blood flow of the placenta.

Now that you know everything that this incredible project is developing, how do you think it could impact medicine worldwide?
