Space can alter a person's DNA & The immune system takes a hit & A human body may experience a decrease in muscle mass as a result of space travel

 


Space can alter a person's DNA


Although astronaut Scott Kelly's overall health was deemed to have remained "good" throughout the year he spent in space, it was discovered that his DNA had changed as a result of his time above the Earth. USA Today reports that it was also discovered to have done so permanently for about 7% of his genes. Although some of Kelly's DNA changes, such as damage to his eyes and a thickening of his carotid artery, could be seen on a clinical level (via Time), the majority of the changes, which are now referred to as "space genes", were largely observable at the microscopic level. 


Other striking qualities that were adjusted in Kelly were said to connect with his "resistant framework, DNA fix, and bone arrangement organizations, among other physical processes", uncovered USA Today. 


According to the researchers, the degree of change was comparable to that which would occur in humans subjected to stresses such as mountain climbing or SCUBA diving. According to NASA, the stresses placed on the human body as a result of various spaceflight dangers like radiation, gravity, and a closed environment appear to cause inflammation and other stress symptoms, which in turn affect gene expression, as a 2017 study demonstrated


The immune system takes a hit


According to the University of California at San Francisco, "scientists have been aware since the early Apollo missions that space travel can alter the body's immune system, and not necessarily for the better". According to UCSF, some astronauts have even experienced the reactivation of dormant viruses, like the chickenpox virus. Space's relative lack of gravity has been blamed largely for the problem for many decades.


According to In Tech Open, "microgravity" can cause fundamental changes in the body's response to stress and perceived threats, some of which may be temporary while others may be permanent. Additionally, it may alter the closed environment of space travel to a lesser extent, increasing one's exposure to the same microbes from the same sources without providing an opportunity for one's microbiome to strategically develop and change (via time). 


However, in a study that was published in Scientific Reports in 2021, researchers identified a more specific cause: space travel causes T-regulatory immune cells to activate abnormally. That review, out of UCSF and Stanford College, zeroed in on the safe framework and strength of Millie H U G H E-S, the "main female payload expert to circle Earth", who passed on from leukemia in February 2021


A human body may experience a decrease in muscle mass as a result of space travel


Following his return to Earth, astronaut Scott Kelly said that he experienced some of the signs of muscle loss, such as soreness, stiffness, and weakness. In point of fact, the human body is at risk of losing muscle mass during and after space travel, particularly prolonged space travel. 


The issue of "skeletal muscle atrophy" as a result of space travel was the subject of a previous study that was published in the FA SEB Journal. This is known to be brought on either by the lack of gravity or by the fact that there is only so much room to move around in space. The body needs to work less to move itself when there is less gravitational force exerted on its muscles and bones. Therefore, despite the fact that an astronaut might be engaging in regular physical activity on a daily basis, they might experience muscle atrophy in a manner that is comparable to that which occurs to people who are placed on prolonged periods of bed rest.


According to the BBC, astronauts must exercise for at least two hours a day to prevent muscle loss—not just gentle yoga or a run on the treadmill. Instead, researchers have developed "odd-looking contraptions" that are intended to increase the amount of effort required by the body when exercising in microgravity (via BBC)

What Is Difference Between Chia Seeds And Flaxseed

Image
  Certain seeds have gained a reputation as superfoods in recent years. Examples include the well-known chia and flax seeds. Both have been linked to health benefits such as a healthier heart, lower blood sugar levels, and protection against certain types of cancer. However, many people wonder which of the two seeds is actually the healthiest. Both are extremely rich in nutrients. To answer this question, this article looks at the scientific evidence that supports each The Saliva Hispanic plant, more commonly referred to as the chia plant, is the source of the tiny oval-shaped chia seeds. Chia seeds are slightly larger and flatter than flax seeds. Flax seeds, on the other hand, have a slightly nuttier flavor than chia seeds. However, incorporating both kinds of seeds into a variety of dishes is simple Nutrition comparison Comparative analysis of the nutrients present in chia and flax seeds The major nutrients contained in a 1-ounce (28-gram) serving, or approximately 4 tablespoons,...

Overconsumption of Common Red Food Dye May Lead to Inflammatory Bowel Disease

Image
  Allure Red AC, a synthetic dye found in popular foods like Skittles, Doritos, Gatorade, Jell-O, and Fruit Loops, has been linked to an increased risk of developing inflammatory bowel diseases (I-B D S) such as Crohn's disease and ulcerative colitis if consumed frequently. The dye, also known as FD & C Red 40 and Food Red 17, is thought to have negative effects on gut health and increase inflammation, according to a small study done on laboratory mice. The study, which was recently published in Nature Communications, found that the additive directly breaks the gut barrier, which helps keep bacteria from getting in, and that it also makes more serotonin, a hormone and neurotransmitter in the gut. According to the report, this reaction alters the microbiome of the gut, making people more likely to develop inflammatory bowel conditions. What we have found is striking and alarming, as this common synthetic food dye may be a dietary trigger for I-B D S, said senior author W-A L-I U...

Border violence displaces 76,000 in Lebanon: Hezbollah

 The International Organization for Migration (IOM) of the United Nations reported on Friday that nearly three months of nearly daily fighting along the border with Israel had resulted in the displacement of more than 76,000 people in Lebanon. The boundary region has seen a flood of viciousness since early October, with blow for blow trades of fire forging ahead with Friday between Israeli powers and Hezbollah. In a report distributed on Thursday, the IOM said that the heightening had uprooted 76,018 individuals, predominantly in areas of southern Lebanon lining Israel. More than 80% of the dislodged Lebanese are remaining with family members, as per the report, and just two percent housed in 14 aggregate sanctuaries spread across the south of the country, predominantly in the seaside city of Tire and in the Hasbaya locale. The remainder, according to the UN agency, have relocated to homes or apartments further from the border. Cross-line brutality has left 175 individuals dead in ...
