Donetsk surgeons save a patient with a bullet wound to the heart
A team of doctors in the Donetsk People's Republic succeeded in saving a patient with a bullet wound to the heart, after they removed a bullet that remained stuck in the membrane that surrounds the heart.
The Minister of Health of the Donetsk Republic, Dmitry Gartsev, said in a statement to "Novosti" agency, "A 36-year-old man was hospitalized with shrapnel, and after taking a medical picture, the team noticed the presence of a foreign body (bullet) in (the surrounding membrane). with the heart).
Doctors in the Cardiac Surgery Department quickly operated on him, and succeeded in removing the bullet, before transferring the injured person to the Neurology Department to continue receiving the necessary treatment.
The Minister of Health of the Republic of Donetsk confirmed that the doctors in this hospital have great experience in dealing with such cases of people injured by bomb fragments and mines, and they receive daily cases of this type of injuries that the residents of Donbass are exposed to.
Scientists monitor the health of space station astronauts whose mission period has been extended on the station
SIRIUS Scientific Project Director Sergey Ponomarev announced that scientists at the Russian Institute of Biomedical Problems are closely following the health status of the astronauts, who have extended their stay aboard the station.
In an interview on the subject, Ponomariov said: "Experts at the institute will analyze all the medical indicators of the space station astronauts who were forced to stay on board the station for an additional 6 months.. Of course, every extension of the flight is invaluable data that is carefully processed and analyzed for the development of space biology." and medicine.”
And the "Ross Cosmos" agency had announced earlier that the mission of its astronauts, Sergey Bokobyev, Dmitry Petilin, and NASA astronaut Frank Rubio, will be extended for an additional 6 months until September 27, due to the emergency situation that occurred with the vehicle that took them to the station.
Prokopyev, Betlin, and Rubio arrived at the International Space Station on September 21, 2022, and were supposed to return to Earth in March 2023, but on December 15, the Soyuz MS-22 vehicle that transported them to the station was damaged due to an external factor, and on February 24, Russia sent a spacecraft. Soyuz MS-23 towards the station to be used to return the mentioned astronauts to Earth, and it was decided to extend the stay of the astronauts on board the station until next September.
Dates their benefits and harms
Dr. Angelica Duval, a Russian nutritionist, announced that dates are a useful food, but excessive consumption of them leads to weight gain.
In an interview with Radio "Sputnik", the expert indicated that dates are a useful food item, but this depends on their quantity and quality, so she explains how to choose and eat dates.
According to her, dates are rich in dietary fiber that positively affects the intestines and gut microbiome, and dates improve sleep and skin condition.
She says, "Dates contain a high percentage of silicon, which stimulates the production of collagen, which is necessary for the skin and beauty of women. Dates also contain a good proportion of chromium, which enhances insulin function and regulates the level of glucose in the blood. Dates also contain the amino acid tryptophan, which positively affects mood." It is useful for those who have trouble sleeping.
And she adds: Dates contain high calories, which makes them an important source of energy. However, increasing it in the diet leads to weight gain. They also contain a lot of sugar, so in certain circumstances they can complicate the work of the gastrointestinal tract.
And she says: "It is better to eat dates alone or with fruits and vegetables, so that they are digested naturally and do not remain in any part of the digestive system and do not cause the formation of gases. Therefore, I recommend eating 3-4 grains of dates per day, and it is better in the first half of the day. Because When taken before bed, the sugar will continue to be digested throughout the night, which puts a burden on the digestive system.”
According to her, people with diabetes can eat dates after the approval of the attending physician. It advises that dates should be washed before eating them. Source: Novosti
“Only if we have years to prepare.” NASA confirms that humanity can deflect deadly asteroids with missiles!
Four new studies confirm that NASA's DART mission, which smashed a rocket into the asteroid Dimorphos, altered the asteroid's trajectory and could one day save Earth, given enough time to prepare.
"I was thrilled when DART hit a head on an asteroid in the world's first demonstration of planetary defense technology, and that was just the beginning," said Nicola Fox, associate administrator for the Science Mission Directorate at NASA Headquarters, in a statement . from a potentially dangerous asteroid by changing its trajectory.
NASA launched the Double Asteroid Redirect Test (DART) mission in late November 2021, after five years of planning. The goal was to test a planetary defense theory called a "kinetic collider" technique - essentially changing the trajectory of an asteroid by hitting it with a rocket at high speed.
And in September 2022, NASA's DART spacecraft successfully collided with the asteroid Dimorphos, a 525-foot (160-meter) wide "mini-moon" orbiting a larger asteroid called Didymus, about 7 million miles (11 million km) from Earth. NASA initially reported that the force of the impact shifted Dimorphos' orbit around Didymos by about 33 minutes, successfully reorienting the smaller space rock. (None of the asteroids ever posed a threat to Earth, but the asteroids' size and combined orbit made them ideal targets for the mission.)
Now, four new studies published on March 1 confirm that the mission was more successful than NASA engineers initially expected — and that kinetic impact technology is indeed a viable way to protect Earth from potentially deadly asteroids in the future.
The first of the new studies report DART's successful impact with the asteroid in detail, recreating the timeline leading up to the impact, the location and nature of the impact itself, and the size and shape of Dimorphos. The paper concluded that the successful impact with the asteroid and the resulting change in Dimorphos' orbit shows that "kinetic collision technology is a viable technology for potential Earth defense if needed."
The study also indicates that intercepting an asteroid roughly the size of Dimorphos is possible without a prior reconnaissance mission, as long as scientists have several years - or preferably several decades - to prepare for the asteroid's approach.
The second study uses two different methods to independently confirm the 33-minute deceleration of Dimorphos' orbit, while the third paper calculates the momentum transferred from the DART spacecraft to the asteroid. The impact immediately slowed the asteroid's orbital velocity by at least 0.1 inch per second (2.7 millimeters per second), thanks to both the wrecking spacecraft's momentum and the massive plume of dust ejected from the asteroid's surface after the impact.
Since then, that trail of dusty debris has been seen stretching out into space for thousands of miles, turning Dimorphos into an incomprehensible type of asteroid called an "active asteroid" — essentially a space rock that orbits like an asteroid but has a tail like a comet, the final paper says. .
While scientists previously predicted that active asteroids are caused by collisions, the shift has not been seen in real time until now.
The findings pave the way for a "bright future for planetary defense," Jason Caleray, mission area executive officer for civil space at Johns Hopkins Applied Physics Laboratory, which co-manages the DART mission with NASA, said in the release.
