Subconsciously, Chelsea Wood dreams of becoming an ocean biologist, studying the lives of dolphins or diving deep into the sea to solve the mystery of the vast animal world. She has a special fondness for sea snails, spending time watching each little animal slowly moving inside the mini “laboratory”, a wooden basket. It took more than 20 years, Chelsea Wood, then known in the world of marine biology at the University of Washington, realized that the childhood world in a snail shell as a child hides life from the larvae. The flatworm species Cryptocotyle lingua (a common fish parasite), in the naive thinking of a young age, looks extremely adorable and has the charm of two black-eyed dots. Wood couldn’t take his eyes off the bizarre creature, and then constantly questioned their origins, so much so that he said, “One day, I’ll know who they are.” Going to college, Wood spends most of his time in the lab with his … stupid friends. Wood’s biological world lives on its host, like an outcast in the animal universe. Apparently, the scientific community is indebted to Chelsea Wood (et al.), When the researcher initiated the movement to preserve the parasites has always been estranged by science. The microscopic, “parasitic” world must make up nearly half of all known animals on Earth, but not all species are harmful to the host, including humans. The parasites make up nearly half of all known animals on Earth. Imagine one day in the next century, 10% of parasites disappear due to climate change, there is no suitable host, what will happen? Wood is concerned, but we’re indifferent. The International Union for Conservation of Nature only lists a few species of mussels or lice parasites as “high risk”, while the parasite world is extremely large. Chelsea Wood said that, neglecting the parasite, is accepting failure in biological science research. Scientifically contested, critically opposed the views of anyone who supported Chealsea Wood. Biology preserves the fallacy, that we are taking slow steps … but surely to explore the parasite world, not forget. A few support Chelsea Wood, believing that the achievements in parasitic research open up potential for breakthroughs in medicine, ecology and the history of species development. The charm of the parasite lurks within the ancient genetic resources to evolve, from the tiny “super evil” crustacean ready to kill the fish’s tongue to the wasps with venom that paralyzes the brain of cockroaches. We still envision creatures swung, stained and frightened, but the parasitic world impresses in their own way, and holds a key part of all species’ lives. Many, but not all Humans are superior animals, but share the same fate with the vast majority of other species such as lions, zebras or even fish and shrimp. That is, we all become hosts of many parasitic groups, even though humans do not show hospitality to them. Science believes that hundreds of different parasitic species have evolved to adapt to the body, and then attach their lives, including many generations to come, to the human body. Chealsea Wood doubted, from the time she was sitting in the university lab, about the parasite’s ability to “grow like a mushroom” – a moment when she thought of herself as a nutritious buffet. energy for any hunger in the biological world. Big idea met together. When ecologist Skylar Hopkins (University of North Carolina) defined the concept of parasitism, Wood seemed to open his eyes. The nature of the parasite is an incompatible symbiotic relationship between species, in which one species is a parasite, one is a parasite, the other is a host or a host. Just imagine this simple: species of parasites are not wild “race arms” like hunting – being eaten, but the trick of choosing a “leisurely” life with a big partner. Wood, and then Hopkins, foresaw that nature doesn’t like emptiness, and if given the chance, something evolved to fill that void. This becomes the foundation for the two scientists to mobilize a wave of in-depth research on parasites towards preventing the endangered threat of many species. New England buffalo leech suddenly disappeared for the past 10 years. Life on Earth formed inside a mixed bowl of soup, with primitive drops of Coacervate, making up countless creatures. The parasite thus evolved, over billions of years, from a single-celled microorganism to today’s complex vertebral body. Amateurs will be shocked if they know that parasites exist everywhere, from parasitic fungi, parasitic worms, to parasitic birds, even demon bats with their favorite “food” being the blood of other animals. The oblivion of science made Hopkins speak, and like Wood at first, received only the shake of his head. The Wood-Kins couple did not give up, but quietly enlarged parasite conservation research groups in the US, then spread to Europe, starting to implement a global plan in early 2021 with the media front: Journal of Biological Conservation. Ten years of tracing parasitic science, underwater or on land, are frustrating days when Wood-Kins has only kept two “ancient” data samples from the 1940s. Death and death – the host dies, the parasite dies, without any recorded evidence. The endangered rare dwarf pig in the foothills of the Himalayas made Chelsea Wood and Skylar Hopkins discouraged to learn that this pig-like blood-sucking lice have hardly disappeared. And what makes Wood-Kins want to give up most is his ambition to eradicate a parasitic louse on the California Falcon, or the New England buffalo leech that has been suddenly missing for the past ten years. Normalization of relations One winter night in December 2020, Skylar Hopkins received a long email with concerns about the world of parasites. How terrible would that biological universe, if one day disappear, be? Hopkins quietly painted a pale picture: the parasite is not worrying, only afraid that the ecosystem will “explode” without the parasites. Some people consider the female parasite needs to adjust the population, limit the individual quantity of the species to keep the balance for the ecosystem. Some people assume that no parasite means that many species lose their food source. Hopkins believes this, because some parasites transform their hosts to evolve, manipulate the “mentality” of new owners, turning new hosts into good prey for other species. Hopkins called this a talent for hypnosis, she discovered in the horse mane worms (Nematomorpha) specialized in cricket parasites, thanks to the substance capable of destroying the nervous system that prompted the owner to voluntarily jump into the water and drown. The host dies, the horse maneworms will escape and begin a new cycle with the next victim, while the crickets become food for freshwater salmon. With Chelsea Wood, humans do not rush to a universe without parasites. In many countries like the United States, the disappearance of some intestinal parasites has caused many confusing autoimmune diseases. Thinking explains it in a way: the immune system evolved along with an “association” of parasites and protozoa, so losing this association begins to attack itself. That is why many people with Crohn’s disease (chronic trans-walled enteritis) have sought a cure when rebalancing the intestinal ecosystem with some parasitic species. Horse mane worms are capable of hypnosis, causing the cricket host to commit suicide. Obviously, the movement Wood-Kins initiated, which made even the hardest of people more or less happy. Dr. Bobbi Pritt, for example, famous at the Mayo Clinic for his “anti-parasitic” view, is always busy carrying blood tubes containing dozens of malaria parasites, looking closely at the diseased brain tissue. Toxoplasma curvature to nest, or cure ulcers from sandfly bites. Blog page “Poisonous, Crazy but Beautiful” was born, towards the medical point of view is to remove pathogenic parasites but need to dig deep into research and be ready to preserve when needed. It seems that Wood and Hopkins have successfully conveyed the message: we do not need to love parasites, but should “normalize” their relationship when there are many hidden parasitic mysteries to nature and species themselves. people. With mother of nature, understanding first and then knowing what the next step should be …

The former US president has criticized the South Korean president as “weak” as a leader and negotiator. “We have been treated like idiots for decades. However, I have made them pay billions of dollars more for the cost of the defense the US provides,” he stressed. “The Biden administration has not asked for the additional billions of dollars that Korea has agreed to pay us,” Mr. Trump added, referring to incumbent President Joe Biden. During his presidency, former President Trump has identified himself as the leading negotiator in peace talks on the Korean peninsula. He first met Mr. Kim during the first summit between the two countries in June 2018 in Singapore. The two later expressed good sympathy for each other. North Korean leader Kim Jong Un and former US President Donald Trump. Photo: AFP. The two leaders have met twice again during Trump’s time in office, and North Korea has suspended nuclear and missile tests. However, analysts say Pyongyang will continue to push ahead with its weapons programs. In March, South Korea agreed to pay an additional 13.9% for the cost of maintaining US forces stationed in the country. Thus, the six-year “special measures agreement” will replace the previous US-Korean agreement that expired at the end of 2019. Under the new agreement, Seoul will agree to pay 1,180 billion won ($ 1.03 billion) for 2021. This is lower than the $ 5 billion required by Trump, but this is the largest annual increase in the near future. 2 decades. The financial dispute has rippled the two countries’ security alliances since Trump has repeatedly accused South Korea of ​​being a “stalker”. Washington currently has about 28,500 troops in South Korea to protect the country from its nuclear-armed neighbor North Korea, while also protecting US interests in Northeast Asia.

Can pregnant women eat snails?

Snail is a fairly popular dish in our country. Snail dishes are extremely attractive to women. During pregnancy, pregnant women should eat a variety of foods to supplement all nutrients for the body. Including dishes made from snails.

Benefits of snail for pregnant women

Pregnant women can eat snails and snails are very good for the development of the mother’s pregnancy

• In snail meat also contains phosphorus. This substance works to support energy metabolism, maintain the number of bones and regulate nutrients of the body.

In addition, there is selenium in the snail. This is a very essential substance for the body, not just for pregnant women. It helps boost immunity, reduce the risk of cancer, cardiovascular disease, bone and joint …

Pregnant women can eat snails but must pay attention to the following:

• Do not eat snails in the first 3 months of pregnancy. Because at this time the mother’s body has not adapted to the presence of the baby in the body, so it is easy to experience digestive disorders. Snail smells fishy, ​​so when eating, it is easy to vomit or have indigestion.

Pregnant women can eat snail but should eat only 2 times a week to avoid bloating

• Preliminary processing of snails carefully. Soak the snail with water to wash the rice, vinegar to let it get rid of the mud and then wash it off. When boiling, the snails must be boiled for a long time to ensure the destruction of the worms and parasitic worms in the snail.

• Do not eat more than 2 snail meals per week. Eating too many snails leads to bloating.

Suggestions for mothers to elect some delicious dishes made from snails

• Grilled snail with green pepper

Prepare about 1kg medium-sized snail, 300g green pepper and spices (salt, sugar, vinegar, fish sauce, chili garlic, lemongrass, lime leaves …). Snails, after buying, soak them in rice water for 1-2 hours and then boil them thoroughly with lemongrass leaves and lemongrass. Marinate the snail meat with spices according to your mother’s favorite taste. Finally, put the snail in to bake at a moderate temperature. Be careful not to cook too carefully because the snail will lose its appetite.

Grilled deer snail with pepper is an easy and delicious dish for pregnant women to try

• Bitter snail stir-fried

Also prepare about 1kg of bitter snail with spices (cooking oil, soy sauce, salt, tomato sauce, wine, ginger, garlic, chili, pepper, lemongrass, lime leaves …). Wash and soak the snails in rice water for about 6-8 hours. Then take out and cut off the tip of the snail. The goal is to make it easier to remove the snail meat when eaten. Boil oil for all prepared seasonings and stir fry. Then pour the snail into the pan, quickly and evenly let the snail soak the seasoning. Finally pour a little water and boil for about 12 minutes to enjoy.

Snail is a very healthy food. So pregnant women can eat snails. However eat in moderate amounts. And do not eat in the first 3 months of pregnancy. Up to now, the notion that a mother is pregnant to eat a baby snail gives birth to a few words, a lot of spontaneity is not scientifically grounded.

Many housewives often have a habit that just wash the vegetables three times because the vegetables will run out of dirt. But in fact, this habit only helps you to remove dirt and impurities, but if there are chemicals, they will not be washed away.

As for vegetables that are still contaminated with pesticides or chemicals, they cannot be removed. Besides, in many vegetables can contain a lot of parasites. And if you want to get rid of these parasites, you need to wash the vegetables under the tap water and wash them carefully one by one and soak them in a vegetable detergent solution.

Do not over-boil the vegetables

Cover the pot when boiling vegetables

Most housewives have a habit of swinging the pot when boiling vegetables, not completely wrong, but it also helps you retain the nutrients of the vegetables. But in fact, the fact that you cover the lid when boiling vegetables makes it difficult for chemicals to evaporate in high temperature conditions. In addition, the lid on the pot when boiling vegetables can easily make the vegetables yellow, less green and beautiful.

After cooking vegetables, do not eat immediately

Many families often cook rice and foodstuffs very early but they do not eat right away due to their busy work. Your family just finished boiling, that’s when the vegetables will be green, beautiful, and the most delicious to ensure the nutritional value of the dish. Therefore, you should eat now to ensure the nutritional value of the dish.

Do not cover the pot when boiling vegetables

And when you do, then reheat, the vitamin loses up to 90%. Thus, you should not leave the vegetables overnight, the nutritional value in the vegetables will no longer be available.

Boil vegetables too well

Many women have a habit when boiling vegetables of many housewives is to boil the vegetables too carefully, when they boil them on a high heat, they will cook very quickly. But this is completely wrong because many vegetables with high nutritional value should not be boiled too carefully, because when boiling the vegetables thoroughly, the vegetables will lose their nutritional value and be less delicious. Therefore, when processing vegetables you should know the properties of each vegetable for the best processing.
