Do you know the benefits of chewing gum and the disadvantages of potato chips, research surprised

Health Tips in Hindi: In this way, research related to different things and health is done from time to time all over the world. Some of these are of direct use to us and some are not. There are many researches in these, which are related to our routine life, but we do not know their reality. When this information comes to us, we do not believe it for a while. Some similar research was done by Harvard University on about 1 lakh 20 thousand people. Many surprising things came out in this research. Let us tell you some important things.

1. Chewing Gum Is Beneficial

It has been told in this research that although most people use chewing gum to stop bad breath and change the taste, but chewing it also reduces heartburn. There are many people who are troubled by the problem of acid reflux (stomach acid coming into the food pipe) and heartburn. If such people chew chewing gum after eating, then it gives a lot of benefit. The coming of acid in their food pipe is almost over.

2. Effect of Potato Chips

In this research, the effect of potato chips was also tested. During this it was found that excessive consumption of potato chips leads to weight gain. Scientists doing research found that if potato chips are consumed for 4 years, then an average of 1.69 pounds of weight gain per person in these years.

Discover the world’s most ‘sensitive’ flower

Chinese scientists announced the discovery of four new species of plants from the Gentian genus that can close their petals for a few seconds when touched.

The discovery led by Professor Dai Can from the School of Environmental and Natural Resources Sciences of Hubei University was made on the Qinghai-Tibet Plateau in northwest China.

According to research published in the journal Science Bulletin, 4 new species all belong to Gentiana genus, including G. pseudoaquatica, G. prostrata var. karelinii, G. clarkei and an unnamed species. With the ability to close their petals in just 7 – 210 seconds after being impacted, these are the most sensitive and responsive flowers in the world.

The rapid movement of plants has always intrigued scientists and nature lovers, as unlike animals, they are often considered stationary creatures.

Only a few known species have the ability to open and close leaves in seconds, such as the shame plant and the Venus flytrap. Before the discovery of Gentiana, the only group of plants that exhibited petal-closing behavior when stimulated was Drosera. However, the most responsive Drosera plants also took 2 to 10 minutes to completely close the petals.

“It’s truly amazing to see with the naked eye. Gentiana flowers disappear right in front of you”, emphasized the research team leader.

Gentiana’s rapid petal-closing behavior may be a defense mechanism to prevent repeated incursion by wasps. Due to the insect’s large size and tendency to slit flower tubes to obtain nectar, 98.8% of the flowers that bumblebees “visit” showed signs of closing their wings, the study found. The damage to the flowers is significant. Nearly 80% of the flowers have external damage and 6% damage to the ovary.

Another possible explanation is that these plants have evolved to encourage wasps to transfer pollen more efficiently, since a closed flower will signal to the insect that it has visited before and should look for another flower.

The fish has 555 teeth and loses 20 of them every day

AmericaThe Pacific grouper changes its teeth regularly to continuously have sharp teeth to help grip its prey.

Scientists discovered that the Pacific cotton grouper (Ophiodon elongatus) replaces up to 20 teeth a day, Live Science reported on 11/15. New research published in the journal Proceedings of the Royal Society B.

The Pacific grouper is a carnivore that lives in the northern Pacific Ocean. As adults, they reach about 50 cm in length, but some can grow up to 1.5 m. They have up to 555 teeth arranged in two sets of jaws. Instead of incisors, molars and fangs, the grouper has hundreds of tiny sharp teeth. Behind the first set of jaws is a set of extra jaws that they use to chew food, the same way humans use molars.

To learn about the rate of tooth loss in grouper, Karly Cohen, a biology graduate student at the University of Washington, and Emily Carr, a biology student at the University of South Florida, tracked 20 groupers in tanks. water from a laboratory at the University of Washington. Because their teeth are very small, determining the rate of tooth loss is not simple.

The team put the grouper in a tank of water containing a red dye to dye the fish’s teeth red. Next, they transferred them to a pool of green dye to stain the teeth again.

The experts then examined the fish’s teeth. The teeth that existed from the beginning of the experiment will be red and blue, while the new teeth will only be blue. After examining a total of 10,000 teeth, they determined the rate of tooth loss and growth of the grouper and which teeth were replaced most often.

Specifically, grouper cotton changes about 20 teeth per day. This rate is equivalent to the loss and growth of one tooth per day in humans. Carr and colleagues also found that the teeth in the secondary molars were replaced faster.

The way they change teeth could be crucial to the grouper’s predation strategy, says Kory Evans, an ecologist at Rice University. “The blunter the grouper’s teeth, the harder it is to grab a bite,” explains Evans. The researchers also found that, similarly in humans, the tooth replacement process in the grouper is predetermined, meaning that the tooth is replaced by one of the same type and does not grow larger over time.

The team of experts hope the new study helps scientists understand more about fish teeth and inspires research on many other fish species.

How long do antibodies persist in people who have defeated Corona, know new research

98 percent of people retained antibodies 
Research results were shocking. Research found that 98.8 percent of those who had a Kovid infection had high antibody levels in November as well. The research also found that the levels of antibodies were similar in both those who were present with severe symptoms of Kovid and those who became Kovid positive without symptoms. The result of this research is called ‘Nature Communication’ has been published in. The researchers also analyzed how many more people got infected if one member of the household got infected. It was found that in one out of four cases, when one of the family members got infected, the other members were also infected.

More antibodies when re-infected 
Research lead author Ilaria Dorigti of Imperial College said, ‘We found no evidence that antibodies were present in people with or without symptoms. Levels vary. This indicates that the body’s immune system does not depend on the severity of the symptoms or disease. However, the level of antibodies varied among people. The research found that antibody levels increased in some people, indicating that they may have been re-infected with the virus. Professor Enirco Lavejo of the University of Padua said the May investigation showed that ‘he’ 3.5 percent of the city’s population was infected. Many people did not even know that they had been infected with the corona virus because they did not have any symptoms.

Rare mineral in the teeth of rock chewers

A research team from Northwestern University, USA, for the first time discovered a mollusk nicknamed “a mass of wandering flesh” carrying a rare iron mineral.

Chiton is shaped like a piece of meat. Image: Northwestern University.

Chiton is a large mollusk with the scientific name Cryptochiton stelleri. Their nickname comes from their reddish brown body that looks like a piece of meat dropped from a pan. They live along rocky coastlines. The largest chiton specimen in the world can reach a length of 33 cm. The researchers were surprised to find santabarbaraite in chiton teeth because previously this mineral only existed in rocks.

“The mineral santabarbaraite has only been observed in geological samples in extremely small quantities and has never been seen in biological organisms,” said Derk Joester, an associate professor of materials science and engineering at Northwestern University. know. “We think it might strengthen teeth rather than add weight.”

Chitons need hard teeth because they chew on rocks to get rid of algae and other food. Their teeth are one of the hardest materials in nature and are attached to a flexible tongue-like structure called a radula. Using a variety of analytical methods at the Argonne National Laboratory and Northwestern University’s Center for Atoms, Nanoscales and Experiments, the team found minerals in the tooth junction with the radula structure of chiton.

New research helps scientists understand how chiton teeth are resistant to wear, and develops 3D printing inks that can create super-hard materials with high strength. The results of the study were published May 31 in the journal PNAS. Inspired by the discovery, Derk and his colleagues wanted to produce an ink containing iron and phosphate mixed with a natural compound produced by chiton. As the ink dries, it creates a hard material.

Manchester City coach Pep Guardiola in constant search

Prove again. It would still be there, Pep Guardiola, at the time of approaching this Wednesday, April 28, the semi-final first leg of the Champions League against PSG. To have to demonstrate, the Manchester City coach, that he is this genius of the game that some people take to the skies when others are still reluctant to grant him so much talent?

Yes, the Catalan has yet to convince, and for that to triumph at the top of Europe, as in 2009 and 2011 with Barcelona, ​​but this time with his English team. And thus join the very select club of the five strategists who raised the continental trophy with two different clubs (read below).

What does his pharaonic record and his eight crownings of champion in three major football countries (three in Spain, three in Germany with Bayern and two in England) matter: at barely 50 years old, Pep Guardiola has not managed to win back Europe since leaving Catalonia.

He suffered three failed tries in the semi-finals with Bayern, and four failures before the last four with Manchester City. A glass ceiling to be broken, against PSG, to show that he is not this sectarian that his detractors often criticize, locked in a game of possession and short passes that made his fortune in Barcelona.

The art of the opposite

His career reveals, in fact, more astonishing breaks than strict straight lines. From the player Guardiola first, raised to the good grain of Barça from the age of 13 and educated in the precepts of the mythical Batavian No.10 Johan Cruyff, to the baton in Catalonia for the professional debut of the young defensive midfielder Guardiola. Pep was only 21 years old and a fate all mapped out: Barcelona, ​​forever. He was, of course, faithful to it for ten years, but, the first opposite, joined Italy in 2001, then Qatar.

Two years in the emirate, and a new zigzag: he bounced back in 2006 in Mexico, in the modest club of Dorados de Sinaloa. The goal ? Enjoy the lights of the relatively unknown Spanish scholar trainer, Juanman Lillo. Pep Guardiola is preparing to pass his master’s degrees in playing and comes to be inspired by the one of whom he will say: “He’s the best coach I’ve ever had.” Lillo rather than Cruyff? Another guardiolesque dribble. But perfectly sincere: Juanman Lillo joined him at Manchester City in June 2020, as an assistant.

→ PORTRAIT. Football: Christophe Galtier, the quiet force of Lille

In 2007, it is the return to the fold to coach the reserve team of Barcelona, ​​which passes with him from the fourth to the third division. He assures today that it is the title of which he is the most ” proud “, because acquired with a small team.

The rest, from 2008, resembles the highway to success. But Pep Guardiola was not content to rush to glory. Deciding to let go of the Barcelona racing car after only four years of driving is no small feat. Nobody understands besides in 2012 that he leaves to simply settle in New York with his family. He says that“There is not only football in the life”. No one wants to believe the obsessive.

“A positive madness”

Which still surprises a few months later by signing with Bayern. The rigor of the Catalan at the controls of the Bavarian machine, risk of sparks. But the association works. We discover that the coach knows how to adapt. And that is moreover all that interests him. Reaction of an emblematic Bavarian, striker Thomas Müller, to the passage of Guardiola: “Pep was always in his own world, because he was thinking all day about how to reposition these players to find the perfect formula. A positive madness. “

Taking up a new challenge is the motivation behind Guardiola’s signing to Manchester City in 2016: adapting to English football, its culture of long play and bitter duels. The genius of Guardiola is due to this flexibility. “ He is one of the few coaches who continue to innovate and take risks ”, underlined his counterpart from Marseille, André Villas-Boas, in the fall of 2020. Guardiola or permanent research. His strategic choices sometimes fall short, such as his three-way defense in August 2020 in the quarter-final lost against Lyon (1-3).

But that’s football too. Pep Guardiola has just recalled this by courageously rejecting the recent closed Super League project, then supported by his employer before the club retracts: It is not sport if success is guaranteed or if losing does not matter ”, he had struck the day after the announcement of the project. Because it is the game that fascinates the guy. As in front of the chessboard, he combines. The great master will never be satisfied.


In the footsteps of Carlo Ancelotti

If he won the Champions League this year, Pep Guardiola would join five other trophy-winning coaches with two different clubs: Austrian Ernst Happel (with Feyenord in 1970 and Hamburg in 1983), German Ottmar Hitzfeld (with Dortmund in 1997 and Munich in 2001), the German Jupp Heynckes (with Real Madrid in 1998 and Munich in 2013), the Portuguese José Mourinho (with Porto in 2004 and Inter Milan in 2010), and the Italian Carlo Ancelotti ( with AC Milan in 2003 and 2007 and Real in 2014).

The latter is for the moment the only one to have also won the European Cup as a player (in 1989 and 1990). Pep Guardiola could imitate him – in 1992, he had lifted the European Cup under the colors of FC Barcelona.

2,600-year-old mummy of a woman slashed with an ax

Researchers found a woman named Takabuti died from an ax cut in the back thousands of years ago instead of being stabbed with a knife.

Professor Rosalie David from the University of Manchester and Professor Eileen Murphy at Queen’s University, Belfast, learn about the mysterious death of Takabuti, the mummy of a woman who died 2,600 years ago. Takabuti is said to be of high status who lived in the ancient Egyptian city of Thebes, which is today the city of Luxor. The cause of her death remained a mystery for decades since the Takabuti mummy was brought to Ireland in 1834 and unraveled for the first time in the following year.

The new study uses a variety of techniques including DNA analysis, X-rays, computed tomography, hair sample analysis and mummification materials. The team concluded an attacker could use a battle ax to hit Takabuti from behind while she was running away. The person could be an Assyrian soldier or an acquaintance of the victim.

Previous photos of the mummy revealed that the woman was stabbed in the upper back near her left shoulder and the stabbing was the cause of her death. New research shows the ax used to kill Takabuti and is a common item used by both Egyptian and Assyrian soldiers.

Studying the location and depth of the wound, the team believed that the killer swung the ax down from above with maximum force. The slash cut sharply into the ribs, causing fatal injuries. The weapon is an ax with a sharp edge and half curves, according to the shape of the wound.

Takabuti’s mummy analysis showed that the young woman died between the ages of 25 and 35. Using protein, researchers were able to investigate her health while alive and found no evidence of disease. at the time of death. The title engraved on Takabuti’s coffin reveals the woman is married. According to David, even though he was slashed with an ax, Takabuti died quickly and did not suffer prolonged pain. Maybe the woman is very loved by her family. Her hair was cut neatly after death, curled and carefully styled.

Lodkown increased due to Corona virus, how much our weight increased, research revealed

Lockdowns were imposed last year to control the corona virus infection. People were forced to remain imprisoned in homes. He stopped using computers, Netflix and food a lot as he stopped going out. The result of this can be seen in the report of Jama Network Open published on Monday.

Lodkown increased weight by 2 pounds per month

According to research, American citizens gained 2 pounds per month while living in Quarantine. The researchers analyzed data obtained from 269 participants involved in research on cardiology. They voluntarily reported the measurement of weight from a smart scale with a Bluetooth device and weighed themselves regularly. Researchers collected 7,444 weight measurements for four months i.e. 28 weight measurements from each participant on average.

The participants were about 52 percent women, 77 percent whites and their average age was 52 years. The researchers analyzed the weight measurements taken between 1 February 2020 and 1 June 2020. Their purpose was to find the change in weight from both before the lockdown was implemented and after the lockdown was implemented. The research team found that every 10 days after the lockdown was implemented, the participants’ weight increased regularly by six-tenths of a pound, that is, by 1.5 to 2 pounds more per month.

Research showed small glimpse of big problem

However, many of the participants were losing weight before the lockdown took effect. Researcher George Marcus from the University of California, San Francisco told the New York Times, “We know that weight gain is a public health problem in America, so making it worse for anything is definitely a matter of concern and living in homes The impact of the order is so large that it makes the impact of minor numbers extremely relevant. “

He told the Times that the impact of the lockdown could have been even more widespread for those who were not losing weight before the lockdown. He said that this shows that this is a small glimpse of a big problem. The researchers, however, also said that small-scale research may not be common to the entire American population, but this is an indication that explains what happened during the epidemic. The weight of the participants increased despite their location and chronic medical conditions.

Is Viagra Pill Effective In Increasing The Age Of Men? Shocking disclosure in research

The use of Viagra is not only good for sexual power but it can also be related to the long life of men. New research found that men who used small pills after heart attack reduced their risk of heart attack again.

According to Swedish research, Viagra pills that increase sexual power can reduce the risk of heart attack and heart complications. It is claimed that the drug of impotence sildenafil reduces the risk of heart attack and increases the life span of men with heart disease. Research from the Karolinska Institute has been published in the Journal of American College of Cardiology.

Does the use of Viagra reduce the risk of heart attack again?

Leading scientist Andrew Trafford told the Daily Express that the discoveries are ‘incredibly encouraging’. Scientists analyzed 18,500 men with coronary artery disease who were undergoing treatment for impotence. Of them, 16,500 were using Viagra while 2,000 men were taking sildenafil syringes, another drug to treat impotence. Research showed that men taking regular Viagra had lower risk of heart attack, heart failure, bypass surgery than those taking sildenafil, which helped prolong their lives.

Pill increases age by reducing the risk of heart disease- Research
The American Heart Association says that the problem of impotence in a healthy male may be an early sign of heart disease. Other treatment options are a class of medication called PDE5 inhibitors such as Viagra (sildenafil) or Cialis (tadalafil), which are consumed by mouth in tablet form. These drugs work by inhibiting the PDE5 enzyme to increase blood flow. Researchers tried to know how these medicines used in the treatment of impotence have an effect on patients with coronary artery disease.

Six months before starting treatment for impotence, the participants had experienced heart attack, balloon dialysis or bypass surgery. Doctors say that the risk of recurring heart attack is highest in the first six months. The results suggest that there is a possibility that those using PDE5 inhibitors were healthier than those of alprostadil and therefore had a lower risk. However, more research has also been said to confirm the results of the search.

Sampling bacteria at the ‘Gate of Hell’ to create an antibiotic

RussiaHundreds of thousands of years old bacteria in the one kilometer crater could help researchers deal with antibiotic resistance.

Batagai Crater in Siberia. Image: Siberian Times.

Researchers from the St Petersburg Institute of Experimental Medicine are planning to study viruses and bacteria taken from permanently frozen soil sediments in a giant depression called the Batagai crater to see if they could help. production of new antibiotics or not This tadpole crater near Batagai village, 660 kilometers northeast of Yakutsk, appeared in the late 1960s when the forest in the area was cleared.

Currently, the crater is one kilometer long, 800 meters wide and more than 100 meters deep. This is a treasure trove for scientists around the globe because it contains some of the best preserved ancient frozen soil samples, according to Professor Julian Murton from the University of Sussex, UK.

Experts drilled the permafrost tip from the Batagai crater last year. In March, research will begin at the Yakutsk and St-Petersburg laboratories. The team hopes that the organisms preserved in specimens up to 200,000 years old could play a useful role in the creation of antibiotics.

“I’m going to fly to Yakutsk to pick up the frozen soil to start working, using microbiology and molecular genetics. We find antibiotic resistance very difficult. They are very interested in creating drug prototypes for the treatment of infectious diseases and putting them into production, “said Dr. Artemy Goncharov, head of the Laboratory of Microbial Protein and Genomic Function at the Institute of Experimental Medicine. .

Several other research groups in Russia and Britain are also studying samples of frozen soil from the Batagai crater.

The Siberian tundra is home to many supermassive hollow holes formed by melting permafrost, but the Batagaika crater attracts even more attention with the nickname “Hell’s Gate” by the locals. put. Sensors that track the crater’s growth show that it expands by 20 to 30 meters per year as the ice melts into water and passes away. Climate change is driving this process, releasing gas and mineral ores that have been buried under ice for thousands of years.
