No bacteria?Can drinking soda hangover?August "Science" rumor list quickly watch

Directed by the Beijing Science and Technology Association, the Beijing Municipal Party Committee Network Information Office, the Capital Internet Association, the Beijing Science and Technology Journalists Editorial Association and the Beijing area website jointly jointly published a rumor platform. The Society, Shanghai Science and Technology Communication Association, and Beijing Institute of Science and Technology Institute of Science and Technology were supported by the August "Science" rumor list on August 31, and interpreted 10 recently widely circulated rumors.

"Left -handed" IQ is higher

Rumors: "Opening Bow on the left and right" can effectively exercise the brain, so the "left -handed" people's IQ will be higher.

Truth: "Left -handed" is the leftist. Some people call their right brain highly developed, while the average person only exercises the left brain, so the "left -handed" is smarter. In fact, which hand is accustomed to it, it has nothing to do with IQ. If IQ is tested, there is no significant difference in the left -handed hand and right -handed hand.

"Open your hands on your hands and can improve your brain function." Many educational institutions are used by many educational institutions as methods to enhance memory and improve their thinking ability. But in daily life, whether it is "right -handed" or "left -handed", the brain is parallel to both sides. "Only one hand will make the other half of the hemisphere not get exercise." It is completely wrong.

The longer the eyebrows, the longer the life span

Rumors: Many high -life elderly people have long eyebrows, which shows that the longer the eyebrows, the longer the life.

Truth: The length of the eyebrows changes with the cycle of people's growth. For those who are older, the metabolism becomes slower, and the rate of eyebrows is slowed down, so it is easy to become longer, but it does not mean longevity. In addition, hair is also affected by genetic genes, which varies from person to person. On the other hand, if you have long eyebrows at a young age, you need to pay attention to the external manifestations of the disease. Check it in time. If you are caused by the disease, do not delay. Because young people's metabolic speed is not as slow as the elderly, the eyebrow update is relatively fast.

Goldfish will be killed if you feed too much

Rumors: When feeding the goldfish, do not put too much food to the fish tank, otherwise they will always eat until they die.

Truth: Goldfish is not "supported" to death, but was "stunned". Goldfish feed is mainly live and synthetic fish foods such as fish, insects, red normies, etc., but no matter which one, there will be endless feed left in the fish tank when the feeding amount is too large. Appear. Golden fish after eating increased the oxygen demand due to digestion of food. The food in the water will be decomposed and deteriorated by microorganisms. On the one hand, the broken foods will produce a variety of toxic metabolites and pollute the water body. On the other hand, the microorganisms will also consume the dissolved oxygen in the water during the decomposition process. At the same time, if you feed live food, the food itself will increase oxygen consumption.

Therefore, after feeding fish, the water in the fish tank will occur in water quality and decreased the amount of dissolved oxygen. When the amount of dissolved oxygen in the water is insufficient, the goldfish will cause physical dysfunction caused by hypoxia, which will cause the death of goldfish. Therefore, the goldfish is not actually "not hungry and full". Most of the goldfish raised in the fish tank died because the dissolved oxygen dissolved in the water became "stretched".

Therefore, we must pay attention to "a small amount" when feeding goldfish, and we must clean up in time when there are fish. Of course, you must also pay attention to additional oxygen supply so that you can avoid tragedy.

Twin people's face recognition technology cannot be achieved

Rumors: According to today's technical level, the face recognition system cannot certify people with similar appearances (such as twins). This problem is no solution.

Truth: Theoretically, people who identify similarity will increase the difficulty of identification and reduce accuracy, but it is not unable to do it. In reality, those who are very similar to their parents or familiar people can still be distinguished, indicating that these faces are still different, and artificial intelligence can definitely be recognized -this needs to strengthen the training of the system, such as collecting a large number of large quantities The twin face data is used as a training sample, which allows them to distinguish them during artificial intelligence training and increase identification.

However, AI's deep learning training is relatively energy, and many R & D units believe that there is no need to invest in a few people. There are many neural network layers and nodes of large models, and each training will cost a lot of cost. Therefore, those with similar faces are not technically unable to do, but it is better to use multiple verification (such as face recognition+sound pattern) to solve this problem based on comprehensive considerations such as reducing costs.

Drinking soda can hangover

Rumors: The water in the blood after drunk is reduced, and soda and other soda can quickly dilute the alcohol in the blood to achieve the effect of hangover.

Truth: Drinking soda after drinking can not be unlocking, but it hurts the body than drinking alone, because carbonated drinks can accelerate the absorption of alcohol in the gastrointestinal tract.

The carbon oxide gas in carbonated beverages will not only support the volume of the stomach, but also speed up the speed of alcohol into the small intestine (the small intestine's absorption of alcohol is much stronger than the stomach), increase the pressure of the stomach and induce acute gastroenteritis. People with gastrointestinal diseases themselves, so that "hangover" can make gastrointestinal problems more serious and even lead to gastric bleeding.

When selling old mobile phones, resumption of factory settings can protect privacy

Rumors: Before selling the old mobile phone, the data is empty and the factory settings are restored, and personal privacy will not be leaked.

Truth: The restoration of the mobile phone factory setting only simply restores the system files and the user data is simply deleted. The content of the internal storage chip of the mobile phone has not been completely deleted, just as we delete files on the computer, it can be retrieved through some software. Generally speaking, we delete the data operation, but just release the storage space of the area where this part of the data is located. In fact, the data is still there, unless there is another data in this part of this area. At this time The data will be covered. Therefore, if you want to ensure the security of the old mobile phone when selling the old mobile phone, after the mobile phone restores the factory settings and restarts, you need to use multiple copies of video, download software, etc. to fill the original mobile phone storage memory, cover the original data, and then then cover the original data. Then It can be restored to the factory settings.

"Sterile Egg" does not have bacteria, you can rest assured to eat

Rumors: The "bacterial eggs" popular on the market do not contain Salmonella, no egg fishy smell, and more yellow yolk. You can rest assured that you eat.

Truth: "Sterile Egg" generally refers to eggs that have been sterilized and strictly processed by Pakistan. The internal bacteria content is small, but it is not completely sterile. It is more suitable to call it "less bacteria eggs".

Ordinary eggs are heated through high temperature, and the pathogenic microorganisms contained in it will be killed, so there is no need to excessively pursue sterile. In particular, common food -based pathogenic bacteria Salmonella, this bacteria has a strong low temperature resistance, can survive in the refrigerator for 3 to 4 months, and it will directly die when the ambient temperature reaches 100 degrees Celsius.

The non -fishy smell, egg yolk is more yellow, and rich in nutrients, and it is not the exclusive to "sterile eggs". Whether the eggs have fishy smell are mainly related to the variety of feed and chicken. The color of the egg yolk depends on the feed.

It should be noted that 91%of the protein in the boiled eggs can be absorbed by the human body, and if it is eaten raw, this value is about 55%. Because raw eggs contain some protease inhibitors, it will affect the digestion and absorption of protein. Eat "sterile eggs", it is better to eat ordinary eggs.

Giving watermelon preservation plastic wrap can cause bacteria breeding

Rumors: Sometimes people buy the entire watermelon to eat it once and will cover the plastic wrap. However, the watermelon covering the plastic wrap will create a humid environment for bacterial growth.

Truth: It is correct to store it with plastic wrap after cutting the watermelon. How much bacteria on the surface of the cut watermelon depends on the cleanliness of the tool, the hygiene of the preservation environment, the preservation temperature, and the time of preservation time, and the food preservation of the food itself does not cause the bacteria to increase.

The cling film commonly used in the family is PE film, which is polyethylene plastic plastic wrap. This polymer material has a certain breathability and humidity, which can regulate the oxygen, carbon dioxide and water content around the food wrapped, and play a role in keeping food for food. In addition, the surface of the cut watermelon is covered with plastic wrap, which can keep the water well, and can block the dust and bacteria in the environment. When it is stored in the refrigerator, it can also prevent skewers and cross -pollution.

However, no matter the preservation of plastic wrap or refrigerator refrigeration, the bacteria cannot be prevented from growing and reproduction. If it is put for too long, the bacteria will still increase in large quantities. Therefore, the "pot" of watermelon breeding bacteria should not be carried by plastic wrap, which is mainly caused by the storage time.

Eating liver care often can enhance liver function

Rumors: Many drugs may hurt the liver, and eating liver care products can "replenish" liver and enhance liver function.

Truth: Liver protection drugs cannot be taken casually, and improper use can even cause damage to the liver. If you want to protect the liver, the most important thing is to develop healthy and good living habits. Do not pin your hopes on drugs and health products.

The common liver care products on the market, the active ingredients are generally flying Jimin, which is a zevial ​​lignin obtained from the seeds of the chrysanthemum pharmaceutical plant water and thistle (alias "milk thistle") seeds Classic compounds can play a different degree of protection and therapeutic effect on liver injury caused by liver poison, and are often used in various prescription drugs with liver protection. The difference between the health products with water flying Jimbin as the main ingredient may only be that the content of water flying is lower, but the price is often higher.

However, these drugs generally only have the effect of promoting repair on the liver that has already occurred, and it does not prevent the occurrence of liver disease. Normal people are not meaningful when the liver function does not appear abnormal. Causes the occurrence of medicinal hepatitis.

Another common "liver protection" is actually a common "enzyme". As we all know, rising transaminase is a common indicator for abnormal liver function. Many people choose to take enzymes immediately to restore the transaminase index in the blood to normal levels.

However, enzymes cannot be equal to liver protection. This type of drug only inhibits the activity of transaminase and temporarily restores the indicators to normal. It does not really repair liver damage. The transaminase index that has "restored normal" will "re -ignite".

To make matters worse, taking enzyme -lowering drugs will likely cause changes in the condition to be discovered in time, affect the judgment and treatment of doctors, and cause more serious consequences.

In fact, there is no "cheats" and "shortcuts". In daily life, do not drink alcohol, eat less greasy food, regularly work, stay up late, refuse to abuse drugs, and reduce the burden on the liver is the greatest protection of it.

Oyster sauce is causing more carcinogenic

Rumors: Oyster sauce contains a large amount of sodium glutamate. When heating more than 120 degrees Celsius, it will become sodium (sodium glutamate. Eating too much will cause cancer.Truth: Sodium glutamate is the main component of MSG, which can improve the taste of food.Sodium glutamate is a global -recognized safe food additive. No study has found that sodium glutamate contains toxicity. Therefore, it is false to say that eating more sodium glutamate will cause cancer.In addition, there is no evidence that there is no evidence that sodium Curdine is carcinogenic, and it has no original fragrance.

Of course, it is not appropriate to add sodium glutamate.Because sodium glutamate is also sodium salt, excessive intake can cause blood pressure changes, and excessive intake of infants and young children may also cause zinc deficiency, which affects the development of the nervous system.In addition, oyster sauce is basically added with white sugar, and excessive use of sugar when seasoning will increase the intake of sugar.
