This special spice for whitening your teeth

Although turmeric is known for leaving a yellow stain on various surfaces, it is an effective ingredient for whitening yellow teeth.

Turmeric is suitable for sensitive teeth and even toothache because it has anti-inflammatory, pain-relieving and antibiotic compounds.

In the rest of this article, we will tell you how you can prepare a combination for teeth whitening with the help of turmeric, baking soda and coconut oil. Baking soda contains sodium bicarbonate, which is effective in removing stains on teeth. Also, this substance neutralizes the acids produced by bacteria, and this helps to remove excess plaque on the teeth, which causes tooth loss and gum diseases.

Coconut oil is also very important for oral and dental health and is effective in eliminating bacteria, gum disease, bad breath, and tooth sensitivity. This oil makes the teeth whiter and shinier. To make a whitening paste, combine four tablespoons of turmeric powder with two teaspoons of baking soda. Then add two and a half to three tablespoons of coconut oil. Mix them well until it takes a uniform shape. Put two teaspoons of this mixture on your toothbrush and brush your teeth gently for one to two minutes. Then swirl a teaspoon of coconut oil in your mouth for a minute and then rinse your mouth and teeth with water. Do this several times a week for the first two weeks, but only once or twice a week for the following weeks. This combination will make your toothbrush turn yellow, so it is better to have a separate toothbrush for this. If the skin around the mouth turns yellow due to contact with turmeric, dip a piece of cotton in milk and leave it on the skin for 5 minutes and then wash the face. The excess of this mixture should be stored in the refrigerator.

Warning signs of Alzheimer’s disease

Alzheimer’s disease is a neurodegenerative disease that is associated with gradual onset and continuous progress, and over time it affects memory and other mental abilities such as thinking, reasoning, and judgment, and confronts a person with many problems in performing daily life tasks.

Alzheimer’s is the cause of 60-70% of dementia cases. This disease often occurs after the age of 65 and more in women. Often the onset of Alzheimer’s is slow and it may be difficult to diagnose this disease in the early stages. Three clinical symptoms of memory impairment, visual and spatial defects, and speech impairment can help diagnose it, which is classified into three general groups:

Cognitive disorders

· Memory disorder: to the extent that it becomes difficult to perform daily activities.

Losing time and place: forgetting days of the week, date and time

· Weakness of speech: a person with Alzheimer’s sometimes forgets simple words and substitutes inappropriate words and has grammar mistakes.

· Moving objects: For example, a person leaves his wallet in the refrigerator.

· Impairment in understanding images and recognizing their size and distance: for example, he climbs the stairs, but cannot estimate the height of the stairs.

Mood and mental disorders

Loss of motivation: the person is indifferent to the events of his life and family environment.

Problems in mental thinking: gradual forgetting of numbers and not knowing how to calculate numbers.

· Weakness or reduced judgment: the person does not understand his problems and does not consider it necessary to see a doctor.

behavioral disorders

· Changes in moods and behaviors: the patient’s mood changes quickly, even without any reason, his calm turns into anger.

· Not observing social customs and any serious changes in former habits and behaviors: in the official assembly, he suddenly tells an impolite joke.

Alzheimer’s risk factors

– Age over 65 years

– stroke

– Family history (inheritance)

– Coronary heart disease

– Low education level

– Increased blood cholesterol

– History of depression

Vitamin and folic acid deficiency

– Lack of physical activities and sports

– Smoking

– History of severe head trauma

– Psychosocial stress such as retirement and death of spouse

– Toxins in the environment

Stages of Alzheimer’s disease

1- Initial: the symptoms of the disease appear gradually and the exact time of the beginning of this stage cannot be determined, the most obvious defect is the loss of short-term memory and is seen in the form of forgetting recent events and inability to learn new things.

2- Intermediate: In this stage, the doctor diagnoses the disease and the symptoms of the disease are so obvious that they affect the patient’s social life, work and daily activities.

3- The final stage (advanced): the patient is completely dependent on caregivers. He does not have the ability to speak. Indifference and extreme fatigue are common and the patient is stuck and unable to feed. The cause of death at this stage is often an external factor such as bed sore and pleural infection and not Alzheimer’s disease itself.

Prevention of Alzheimer’s disease

There is no known definitive way to prevent Alzheimer’s, but any action should begin in midlife. It seems that the use of antioxidants, the consumption of foods rich in vitamin E, which inhibits the entry of free radicals into brain cells, exercise and walking, proper and sufficient sleep, performing mathematical calculations, modifying cardiovascular risk factors and medications Effective anti-inflammatory.

It is worth mentioning that people with blood group O have more gray matter in their brain than other blood groups, which has a protective role in Alzheimer’s disease.

The most important properties of thyme that you did not know

Thyme is one of the plants that has many properties, both the plant itself and its oil, but some people, such as those with thyroid problems, should avoid using it.

Thyme belongs to the mint family and has small leaves that are used to treat various infections. Thyme contains vitamin C, A, calcium, magnesium and potassium. The antioxidants lutein and thymonin have made this plant a disease-resistant shield. Two important compounds of thyme, thymol and carvacrol, have strong antibacterial and antifungal properties. There are many properties for thyme, including:

Thyme helps to strengthen the hair follicle and is used to eliminate dandruff. Its oil helps to heal skin acne. Propionibacterium, which causes skin problems, is destroyed by thyme.

Thyme oil

The use of herbal oils and aromatherapy is very important. Thyme oil contains 20 to 50% thymol (a useful substance found in thyme). Thyme oil is effective as one of the useful vegetable oils for treating health problems such as asthma, cough, stomach pain, joint rheumatism, urinary tract infections, heart diseases, migraine and headache. The way to use thyme oil is different according to the type of your problem. To treat skin problems, you can apply a few drops of the oil on your skin, and for diseases such as sore throat or heartburn, add it to a glass of water and drink it. (with doctor’s advice)

Benefits of thyme bath

Thyme bath is one of the types of bath therapy that is used for respiratory problems. Bathing with this plant strengthens the lungs and prevents shortness of breath and chronic coughs. Some women also choose thyme bath as a treatment method to clear the skin and remove pimples and skin acne. Thyme also improves muscle pain. To prepare a thyme bath, pour half a glass of thyme extract into the bathtub and lie in it for about an hour. If thyme extract is not available, you can boil about 50 grams of thyme with water and then strain it and add it to the water in the tub.

Cons of using thyme

Along with its properties, thyme also has a series of side effects. Thyme contains two valuable compounds, thymol and carvacrol, which cause allergies in some people and may irritate their mucous membranes. Thyme affects the pituitary gland that secretes thyroid hormone; Therefore, people with thyroid problems should avoid consuming thyme.

For people who have low blood pressure, it is desirable to use thyme, because it increases the blood pressure level, but it is better for people who have high blood pressure to avoid using thyme, because it increases their blood pressure.

High consumption of thyme affects female hormones, so it is better for women to avoid using it during certain periods such as menstruation, pregnancy, and breastfeeding, or if they wish to use it, consult their doctor.

The number of ants on the ground was announced

The number of ants on the ground was announced

How many stars are there in our galaxy? How many grains of sand are there in the Sahara desert? How many ants live on earth? All these are questions that seem impossible to answer. However, through intensive and extensive data analysis, science is getting surprisingly close to finding solutions to these questions.

When it comes to ants, a group led by Sabine Nooten and Patrick Schultheiss, biologists from the city of Würzburg, conducted this investigation.

Since 2022, Schultis has been conducting research in the Chair of Behavioral Biology and Social Biology at the Julius Maximilian University of Würzburg (JMU).

A 20 with 15 zeros

How many ants are there on the ground? “Based on our estimates, the world’s ant population is 10 x 20 to the power of 15, or 20 quadrillion ants,” explains lead author Sabine Naughton, who recently moved from Hong Kong to Würzburg. It means 20 with 15 zeros. This number is hard to understand, but it becomes clearer when you calculate the biomass of animals. This amount is equal to 12 megatons of carbon. Patrick Schultheis explains: This amount is more than the total biomass of wild birds and mammals and is about 20% equal to the biomass of humans.

In order to calculate the number of ants, the researchers reviewed a wide range of available studies on insects, eventually evaluating about 500 relevant articles and merging them into a database.

The distribution is very different

Ants were known to live in almost all habitats except the polar regions. This study was the first to experimentally investigate the distribution of ants. It turned out that tropical regions have the highest density of ants. In these areas, in addition to weather conditions, local ecosystems also play an important role. Forests and dry areas harbor the most specimens, while ants are much rarer in areas heavily impacted by humans.

Future studies should focus on which environmental effects specifically affect ant distribution. Especially the effect of climate change should be investigated.

An important role in the ecosystem

Why the number and distribution of these insects is so important can be explained with an example. In each hectare of land, ants move up to 13 tons of soil annually. This work has a great effect in maintaining the cycle of soil nutrients and also has a decisive role in the distribution of plant seeds.

But sometimes the effect of insects is negative. Invasive species, for example fire ants, can have a negative impact on local biodiversity and cause significant damage.

The big problem in iPhone 14 camera made news

While many people were excited to buy this flagship phone after the unveiling of the iPhone 14, but the camera system problems blinded their taste.

It seems that many third-party applications have problems with the rear camera of the iPhone 14 Pro model. Users have reported problems such as shaking and shaking and making sounds while using applications such as Instagram, Tik Tok, and Snapchat. It seems that there are problems with autofocus and focus.

In addition to publishing iPhone 14 problem reports on Reddit and Twitter, some users have published videos of these problems. One of these problems is the mechanical sound from the iPhone 14 Pro when Snapchat is opened. Another video showed a similar problem with rear cameras when accessing TikTok.

An Apple spokesperson told Engadget that they are aware of the issue and will release a software update next week to resolve the issue.

According to the Engget website, considering that the mentioned problem is only seen in third-party applications, it is probably a software problem, not a hardware one. Especially, these applications may not work well with the optical image stabilization system of the iPhone 14 Pro, which is probably the reason for the shaking of the phone’s camera.

Two weeks ago, Apple unveiled four new iPhone models, including iPhone 14, iPhone 14 Plus, iPhone 14 Pro and iPhone 14 Pro Max, which are able to send help requests via satellite in emergency situations. Improvements made to the iPhone 14 camera include a new mode called Action for video, which helps stabilize shots.

The price of applications in the App Store became expensive

Starting next month, Apple will increase the price of apps and in-app purchases in the App Store in many countries.

Apple announced in a blog post that the new prices, which do not include automatic subscription renewals, will take effect on October 5.

In a message to designers, the company announced that customers who use Euros, as well as users in Sweden, Japan, South Korea, Chile, Egypt, Malaysia, Pakistan, and Vietnam, will see price increases from October 5.

Apple said the changes in Vietnam also reflect new regulations for the company to collect taxes including value-added tax and corporate income tax at a rate of five percent.

The growth of the value of the dollar has probably been an influential factor. In Japan, prices rose by about 30 percent, a significant increase after the yen’s depreciation.

According to a Bloomberg report, Apple increased the price of its products including Mac, iPhone and iPad in early summer due to currency fluctuations. The euro has had the same fate as the yen and is now traded at the same rate as the US dollar and is likely to fall further.

The death of the famous Russian cosmonaut with the record for the longest stay in space

Valery Polyakov, the Soviet-era cosmonaut who once held the record for the longest stay in space, has died at the age of 80.

After returning from his 438-day journey from the Mir space station, Polyakov said: We can fly to Mars.

Polyakov’s death was reported on Monday (September 19/28) by the Russian space agency Roscosmos.

Roscosmos officials wrote about this: Roscosmos regretfully announces the death of Hero of the Soviet Union, Hero of Russia, pilot-cosmonaut of the USSR, holder of the world record for the longest stay in space, Valery Polyakov. We offer our heartfelt condolences to the relatives and friends of Valery Vladimirovich Polyakov.

He was born on April 27, 1942. Polyakov, who was selected in 1972 with the third group of Russian doctors for astronaut training, traveled to the Mir space station on two long-duration missions. In total, he has been away from Earth for 678 days, 16 hours and 32 minutes. Today, he ranks eighth in the world in terms of total time spent in space.

The Mir space station was a Soviet and later Russian orbital station. Mir was the first human research station in space where humans lived for a long time. The construction of this orbital station began in 1986 and after gradual completion over a period of 10 years, it became the largest man-made space structure and kept this record until 2001. Mir station was a place to conduct scientific studies in various fields, among which biology, physics, astronomy and meteorology can be mentioned. The technologies that were developed with the help of the Mir station made it possible for humans to live permanently in space.

Polyakov’s first mission began with the Soyuz TM-6 spacecraft on August 29, 1988. In this journey, Vladimir Lyakhov as commander and astronaut Abdul Ahad Momand accompanied him as the first Afghan. Liakhov and Momand returned to earth after 9 days.

Polyakov spent the remaining 241 days of his stay with Alexander Volkov and Sergei Krikalev and returned to earth with Volkov on April 27, 1989.

Polyakov’s second and last trip to space was made to investigate the ability of the human body to travel to Mars. On January 8, 1994, Polyakov went into space with the crew of Soyuz TM-18 and began his unprecedented 438-day stay in space.

He returned to earth on March 22, 1995. “We can fly to Mars,” Polyakov told his crew as they landed on Earth.

During the second trip, Polyakov’s medical and psychological condition was closely monitored. He then underwent two tests over a six-month period after returning to Earth. The researchers found that his stay of 437 days, 17 hours and 58 minutes in space did not cause any permanent physical problems, nor did he have any long-term cognitive problems. Although he had a slight drop in mood during the first and last months of his stay.

Roscosmos has announced in a statement: His research has helped to prove that the human body is ready not only for Earth orbit but also for deep space.

Polyakov retired in 1995 and was appointed as the deputy of the Ministry of Public Health in Moscow. Polyakov also participated in the recruitment and selection of new cosmonauts as a member of the Russian High Medical Commission.

The income of content creators on YouTube has increased

In competition with Tik Tok, YouTube introduced a new model for generating revenue for content producers from short videos.

YouTube will run ads on its Shorts video service, and video producers will receive 45 percent of the revenue from those ads. The standard distribution of advertising revenue for videos outside this service is 55%. On the other hand, Tik Tok has allocated 1 billion dollars in credit to pay content producers.

YouTube’s video service has been challenged to compete with TikTok, attracting more than 1.5 billion monthly viewers in late 2020 with the launch of its Shorts service, which includes one-minute videos.

YouTube created a $100 million fund in April to encourage content creators to make videos, and the ad revenue sharing plan, first reported by The New York Times, is a more attractive proposition than the fund, and somewhat similar to TikTok’s offer to Content producers are equal.

YouTube will share a smaller portion of sales with content creators on Shorts to compensate for their significant investment in the development of the service, said Tara Wolpert-Levy, vice president of YouTube.

According to a Reuters report, Google earned $14.2 billion from YouTube ad sales in the first half of this year, up 9 percent from the same period in 2021. But advertising sales in the third quarter had the slowest growth since the statistics began to be published in the last three years. Although global economic factors have been involved in this slow growth, Tik Tok also played a role.

The strongest titanium alloy was developed for the aerospace industry

The strongest titanium alloy was developed for the aerospace industry

Using advanced 3D printing technology, Monash University scientists have created the strongest titanium alloy ever produced, a leap forward in the aerospace, defense, energy and space industries.

In a world-first study of its kind, engineers at Australia’s Monash University have shown how advanced 3D printing can now produce a very strong commercial-grade titanium alloy. This is a real leap forward for the aerospace, defense, energy, space and biomedical industries.

The researchers, led by Professor Aijun Huang and Dr Yuman Zhou, both from Monash University, manipulated a new microstructure through a 3D printing method, resulting in unprecedented mechanical performance.

One of the main advantages of this study is that it was performed on commercially available alloys and can be used immediately. This is a very positive and significant advantage.

“Titanium alloys require complex casting and thermochemical processing to achieve high strength for some critical applications,” Dr. Huang said in a statement. We have discovered that additive manufacturing can use a unique manufacturing process to create extremely strong and thermally stable parts in commercial titanium alloys that can ultimately be directly implemented.

After applying a simple post-heat treatment to a commercial titanium alloy, Professor Huang achieved elongation and sufficient tensile strength of over 1,600 MPa, the highest strength of any 3D printed metal to date. This problem paves the way for the fabrication of structural materials with unique microstructures and excellent properties for a wide range of applications.

Over the past 10 years, 3D printing has led to a new era in metal fabrication due to the freedom in design. That is, it enables the ability to make almost any geometric shape. Currently, titanium alloys are the leading 3D printed metal used to produce parts in the aerospace industry.

Unfortunately, most titanium alloys on the market that are created by 3D printing do not have structural applications. This is especially true for tensile strength at room temperature and high temperatures in harsh service environments.

The main properties of titanium alloy are attributed to the unusual formation of dense, stable and internally twinned nano-precipitates, which are rarely seen in traditionally processed titanium alloys, and the technique used here to solve this problem is additive manufacturing (AM).

Additive manufacturing (AM) is a powerful technology that provides design freedom in this type of 3D creation of titanium alloys. Titanium is generally much stronger than aluminum alloys and lighter than steel, making it more energy efficient.

However, the number of applications and the number of titanium products produced by the AM method are currently still limited in the industry compared to conventional titanium components. This is because the AM products produced today are not structurally strong enough.

Research carried out at Monash University has now developed a more fundamental understanding of the density, segregation of elements and unique solidification structures. Then he opened a window to the properties of nano sediments with higher density and tensile strength.

Now the use of this new alloy can begin immediately, something that is rare for a study or research project. This technique can be used in many industries including the production of car parts and structures.

This study was published in the journal Nature Materials.

Blood oxygen measurement with smartphone camera

Blood oxygen measurement with smartphone camera

Researchers at the University of Washington have stated in their recent study that smartphone cameras can track your blood oxygen levels.

According to Soraya, smartphone cameras will soon be able to help measure your blood oxygen level.

Washington University researchers have stated in their recent study, this technology includes placing a finger on the camera and flash; Artificial intelligence (AI) then decodes the blood oxygen levels from the patterns recorded in the video. This method can identify the early signs of a dangerous drop in oxygen levels among patients with Covid-19 and predict asthma attacks before they occur.

Our body needs 95% oxygen saturation. Respiratory diseases can reduce this amount to less than 90%, and that’s when a person needs breathing tubes or oxygen masks.

The results of this study show that when researchers used a chemical cocktail to reduce the amounts in young volunteers, the performance of this device was accurate 80% of the time.

“Other smartphone apps that do this are made by asking people to hold their breath,” said Paul G. Allen, a student at the University of Washington’s School of Computer Science and Engineering. But people aren’t very comfortable with the program, and are forced to take a breath after a minute or so, and that’s before their blood oxygen levels drop enough to show the full range of clinically relevant data. With our experiment, we can collect 15 minutes of data from each subject. Our data shows that smartphones can work well in the critical threshold range. Information can also be seamlessly transmitted to the doctor’s office.

When we breathe, our lungs are filled with oxygen. It is transported by red blood cells to other organs, which is a sign of fitness and heart health. Viruses and allergies interfere with oxygen absorption. The results of this study showed that smartphones can detect oxygen levels up to 70%, which is the lowest value for pulse oximeters. The researchers trained a computer neural network, or deep learning algorithm, to measure oxygen levels in six participants between the ages of 20 and 34.

The findings of this study, published in the journal NPJ Digital Medicine, are the first step towards the development of biomedical devices that work with machine learning to produce better results.
