What If Scientists Could Discover Habitable Habitats Immediately after Studying the Stars?

What If Scientists Could Discover Habitable Habitats Immediately after Studying the Stars
The search for life in other worlds usually begins with the investigation of planets with the appropriate temperature to form a liquid, but scientists are seeking today to find new standards to track these worlds. One technology determines the positions of the desired planets based on the chemistry of the host star, allowing close examination, without the need for any direct prior knowledge of these planets, and it helps that the stellar and planetary structures are close, subject to the known and very accurate biochemistry.
Although scientists’ focus is on prominent chemical elements such as carbon and oxygen, there are other, less well-known, but extremely important elements, such as phosphorous, fluorine, and potassium.
Planet astrophysicist Natalie Henkel at the Southwest Institute said: “Although they are worthwhile elements, we haven’t gotten enough attention yet, because we haven’t realized how much they need them.”
Henkel and her team presented the preliminary results of their analyzes at the previous meeting of the American Astronomical Society, as they focused on phosphorus in particular, given its use in the process of converting sunlight into stored energy that benefits all living things, from algae to mammals, albeit in small quantities.
What if scientists could discover habitable habitats immediately after studying stars – planets with a temperature appropriate for fluid formation – stellar structures
Henkel said: «It is like preparing cakes, if the cake requires 4 eggs and you only have 3, you will not get your desired cake, this can be likened to phosphorous, with the difference that in practice it is not possible to obtain a sufficient amount of phosphorous».
Based on the foregoing, scientists discovered – while searching for Earth-like life – stars that contain ratios of phosphorous, and began studying the planets in those systems first, but they faced a problem that is difficult to measure phosphorous in stars, due to the low possibility of monitoring a wave of light containing A percentage of phosphorous, either from Earth or using existing space study equipment.
This prompted Henkel to compile the results of observing stellar chemistry in a database, out of more than 6000 stars, only 90 of them contained phosphorous ratios (for comparison, elements in 1,400 of these stars are noted).
It is worth noting that 12 of these stars are familiar to the host planets, which may help us understand the nuances of how phosphorus is related to both the star and the planet.
“We will face a similar problem with other elements, which are biologically important, even in small quantities,” Henkel said.
The limited information generated by Henkel and her team’s research indicates that this methodology is ineffective in selecting interesting planets outside the solar system, but they hope their research will be an invitation to scientists to work to solve the problem of collecting data on these rare elements.
The lack of phosphorous is not necessarily necessary to determine the viability of life outside the planet Earth, as external life – if any – may not require phosphorous at all.
Henkel said: “There may be certain forms of life that do not need the presence of phosphorous specifically, but we are used to life in its presence, so – given what we know now – it was very logical to search for it.”
Henkel discussed the possibility of more beneficial monitoring results than previously, and that this would require more effort in trying to monitor phosphorous ratios, and other biologically important and difficult elements for monitoring. She added: “Although it is difficult to know the exact ratios of these elements, this does not mean stopping tracking them. , We should always do more. ”
Scientists need every observational result they can get in order to track the potential life in other solar systems. It’s really difficult to discover the viability of life on other planets, it’s not simple, we can’t go by ourselves to explore potential planets with life on them, what we can currently do is modeling.

What Will Happen If You Do Not Go out and Expose Your Body to Sunlight?

What Will Happen If You Do Not Go out and Expose Your Body to Sunlight?

What would happen if we stayed indoors for a long time and were not exposed to daylight?

Even if it is not life threatening, getting out, breathing fresh air, and exposure to sunlight is important to your health, as getting out will give you a good dose of vitamin D.

There are many vitamins that we get from food, but vitamin D is absorbed by your skin by a mechanism known as photosynthesis reaction, which occurs when exposed to sunlight.

If you never go out, you will definitely suffer from a lack of this important nutrient, unless you add it as a supplement to your diet.

It is almost impossible to get the necessary amount of this vitamin through food only.

A few types of food contain vitamin D, and foods containing it contain a small amount of it.

Despite this, some people think that the vitamin D that we get from the nutritional supplements is not as good as the vitamin that is made with the presence of sunlight.

But why do we need vitamin D?
Vitamin D is essential for bone health, and it also protects against chronic diseases such as cardiovascular disease and diabetes.

Decreased vitamin D levels lead to poor bone health.

The presence of inappropriate amounts of this vitamin has also been linked to multiple sclerosis and prostate cancer.

In addition to getting nutrients, spending time in the sun is important to your overall health and improves your mood.

According to Life Noggin, sun exposure helps people with seasonal affective disorder.

And not only that, the sun adjusts nitric oxide in the blood and skin, which leads to lower blood pressure, which in turn helps reduce the risk of heart disease.

Although exposure to the sun has many benefits, exposure to it is highly harmful.

Aside from sun damage and the burns it causes, high exposure to natural light can harm the skin’s immune system.

Excessive sun exposure can also lead to injury to skin cell membranes, and increase the risk of skin cancer.

And according to (Life Noggin) magazine, UV rays can damage your skin in just 15 minutes, and here is the importance of wearing sunscreen, hats and sunglasses.

However, getting out is considered good for you as long as you don’t overdo it.

What If All the Antibiotics Stop Working?

Antibiotics
Until the 1940s, one in every twenty children died before completing their first year of life. There was no effective treatment for tuberculosis and pneumonia, and a slight wound might lead to a gangrenous injury, and subsequently amputation. Antibiotics prevent the bacteria from dividing, slowing or eliminating them, which helps our immune cells get rid of the infection.
They eliminate deadly diseases, allow us to open the body during surgeries, and prevent cancer patients from infection. They enable us to raise animals and fish on an industrial scale, and their presence in cleaning products stops the spread of disease. But bacteria are fighting back. In 2016, 700,000 people died as a result of antibiotic-resistant infection, and by 2050, ten million people a year could be at risk. Like us, each individual bacterium differs slightly from others, so when a colony of bacteria encounters antibiotics, it complies with Darwin’s “survival of the fittest” saying. Some members of the colony do better than others, so they live longer and pass on their genes. This makes the next generation a little better in terms of resisting the effects of drugs.
Antibiotics
The next generation also accumulates random mutations, which makes each one slightly different. Some of them become better in antibiotic resistance and the cycle recurs. These small improvements begin to accumulate, and we end up with bacteria that we cannot kill. We are in an arms race with those microorganisms whose molecules develop and disrupt antibiotics, disrupt them, or even flush them out of their cells. Moreover, thanks to diffraction in bacterial biology, when one species develops a method for drug resistance, it can donate its genetic code to another species and then transmit resistance. If our medications stop working, the treatable infection may become fatal again, the risk of infection may increase after surgery, and industrial implants may become impossible. We are in a race against time to find new ways to overcome it, a race that we cannot afford to lose.

What If We Were Able to Block All UV Rays?

UV rays
Scientists divide ultraviolet radiation into three wavelengths based on its behavior. At the most active end, 100 to 290 nanometers, UVC rays have the shortest and most harmful wavelengths. Fortunately, it completely blocks the atmosphere before it reaches Earth. Between 290 and 320 nanometers are UVB rays, which cause skin tan, burn skin and cause cancer. The atmosphere gets rid of about 95% of it, and it cannot run out to our bodies, but the little amount that reaches us is enough to harm our bodies. Finally, between 320 to 400 nanometers are UVA rays, which pass through the atmosphere and penetrate the skin, damaging the structures supporting our cells. This leads to premature aging, cataracts, and sunburn. Blocking these rays can avoid the need for sunscreen, but this will not be positive.
UV rays

What If We Were Able to Block All UV Rays?

Our bodies use UVA rays to make vitamin D, and many animals also rely on UV rays to survive. Butterflies use UV rays in their wings’ patterns to attract the worm, flowers use their petals to attract bees, and red salmon uses them to find food. In the Arctic, UV rays allow reindeer animals to discover wolves whose skin and urine appear black in snow. This is just the tip of the iceberg; research has shown that dozens of other species can see across the UV spectrum. If we get rid of UV rays, they will all be left in the dark.

What Would Happen If You Shot a Bullet Back While Moving Forward at the Same Speed

gun with bullet coming out
Supposing you move at a speed of 300 km/h, and for some reason, you decide to hit a target, you take out a pistol and point your back.

In this case, you are aiming in the opposite direction of your movement and supposing that the bullet also moved at your same speed.

So, you are moving forward at 300 km/h, and the bullet was fired at the same speed in the opposite direction.

What will happen to the bullet for you?

There are different answers to this question depending on specific circumstances. The short answer, however, is the following:

– You are traveling on a specified path at a speed of 300 km/h, and let’s say it is the speed “y”.

– The bullet fired in the opposite direction at a speed of 300 km/h, so we call it minus y. “- y.”

– So you are traveling at a speed of y, and a shot was shot at a speed of ‘-y’.

– This means that – Y + Y = 0, so the bullet should drop straight down, that’s right, once you hit the trigger the bullet will collapse immediately.

But in reality, the issue is more complicated than this
First, even if the bullet moves at an average of 300 km/h, it needs some time to reach this speed.

When you press the trigger the projectile will not gain this speed at once, but it needs some time to accelerate, so when you press the trigger the bullet will accelerate in the gap of the pistol until you later reach the speed of “-y” and cancel the effect of your “speedy” movement, so in reality, it will not fall The bullet directly, but it will move a small distance from the point from which it was fired.

This answer also does not take into account air resistance, and of course, there is air resistance, besides that the bullet will rotate inside the pistol gap.

Resisting the air and spinning inside the pistol’s bore will prevent it from going completely straight forward, and you will end up staying inside the pistol groove, that is, you will not fall from it.

What Will Happen If I Open the Plane Door During the Flight

What Will Happen If I Open the Plane Door During the Flight
Flying causes stress for a variety of reasons, from long lines at airports to children screaming on the plane. Flying provokes us and makes us nervous. If that’s not enough, planes are a perfect filming scene in movies to portray a misfortune.

The media coverage of aviation and terrorism accidents also amplified people’s fear of flying. We look at our fellow travelers that they may lose their minds and try to open a door during the journey, to condemn us all to death.

What will happen if I try to open the plane door during the flight? 

Nothing will happen. Of course, the flight crew will restrain you and arrest you when the plane lands. But nothing will happen to the plane, why? Because you will not be able to open the door; pressure will prevent you from doing so.

Pilot Patrick Smith says: “Think of the plane’s door as a drain gasket fixed to the plane’s internal pressure. Almost all aircraft doors open to the interior. Some of the doors are pulled up towards the ceiling and others open outside but first open inside. “And even a macho person can’t beat the locking strength of doors.”

The pressure inside the cabin is much higher than the pressure outside. So, a person needs to pull the doors with the power of a superhuman. While flying the plane at the fixed height of the flight, the pressure inside the cabin is 0.7 or 0.8 standard air, which equals about 5 to 5.4 kg of force per square inch. This is what you are trying to beat!

Now, you may want to know what happens at low altitudes. As a reminder, this is for science’s sake, so please don’t take it as a personal challenge. Even a difference of 15% ؜ of standard air pressure is considered too strong for a human to overcome. The doors can only be opened when the plane is close to the ground and very close. In the event of an emergency during take-off or landing, it is easy to open doors to release inflatable slides.

If you can open the door in the air, this means that you have more problems. This means that the pressure in the cabin of the plane is low.

The subject can be not dramatic cinematic, but it can be just as deadly as the explosive depressurization which happens when the cabin is damaged as it did in the unfortunate case of Southwest Airlines a few weeks ago. One of the engines exploded, breaking a window and partly pulling a woman out of the cab, and she died from injuries from the engine debris.

The air accelerated out of the cabin due to the high pressure, and the oxygen masks were opened automatically. At low atmospheric pressure, the human body cannot absorb enough oxygen and ultimately dies due to its deficiency.

In the case of Southwest Airlines flight, the pilot, Tammy Joe Schultz, had the skill to make an emergency landing before any of the passengers on the flight were affected by hypoxia. Selfies of the plane showed that almost all of the people were wearing oxygen masks incorrectly. People have to cover their mouths and noses!

Even if you are at a height that allows you to open the door, you will not be able to do that, as the “Cooper blades” device will prevent you. This mechanical device was invented during the 1970s after BD escaped. Cooper is on a plane carrying a large amount of cash hopping from the plane using an umbrella. He managed to open the door because the pilot lowered the cabin pressure first.

You should not be afraid that a passenger will open the door because they are honestly unable to do so, and you should not be afraid of flying in general. In 2017, the safest year in commercial aviation, there were only 10 fatal accidents out of 36.8 million flights!

What Happens If a Person Eats Uranium?

Uranium
What Happens If a Person Eats Uranium?


If we look at the periodic table of elements, we will find many names that we are used to seeing in the food labels we eat, such as calcium, iron, magnesium, etc., and if we look down the row in the table we will find other names that we might get used to hearing when talking about nuclear agreements or energy projects on TV. Like uranium, so what would happen if uranium was a component of the foods we eat.

Uranium Properties

We should take a look at the most important characteristics of this element, which are:
Uranium is an element of atomic number 92.
Uranium is denoted by U.
Uranium is a metal mineral.
Uranium is a radioactive element.
Uranium is famous for its white color, which tends to be silver.
Uranium falls into the actinide chain in the periodic table.
Uranium is a very heavy and heavy metal.
Uranium is found naturally in both water, rocks and soil.
Experts manipulate the three uranium isotopes after being extracted.
Less radiation in uranium is used to make lead or paint.
The most radioactive uranium is used in the nuclear weapons industry and in power plants.

Do We Eat Uranium in Our Daily Diet?

If you think that you are far from being exposed to uranium because you are not working in the defense field, or at a power plant, and therefore you are protected from exposure to uranium radiation then you are wrong, because exposure to the uranium component occurs more than this, as there are certain crops like potatoes The turnip is rich in uranium, of course there are other foods that contain uranium, but these two types are the most absolutely, and the EPA says that the average person eats 0.07 to 1.1 micrograms of uranium per day.

If you are worried about this, there is no need for that, because you will not have to stop eating those foods, as the amount of uranium consumed daily does not constitute any harm to you so you do not have to worry, especially since the human body finds it difficult to absorb the uranium component as it is, where 95 to 99 percent of uranium is excreted in the feces, and most uranium is excreted in the urine in just 24 hours, so the rest of the uranium in the bones is very small, and the uranium intake is much less toxic than inhaled.

What Are the Results of Eating Uranium?

Uranium is a word we hear a lot when talking about energy or nuclear, but it is one of the elements of the periodic table that also includes the elements we eat, such as iron, magnesium, calcium, etc., so what would happen if a person picked a spoonful of uranium and started eating it, that is, what would happen if uranium was not It is taken through some foods as we explained in small quantities, and was it the main dish for your food instead of being a rare item in the food?

Of course it will not be surprising if we say that consuming high doses of radioactive materials increases the chances of developing cancer, but these effects appear in the long run, and they are negligible effects compared to the immediate effects that occur from the chemical toxicity of uranium and other radioactive materials, and target uranium in The first place is the kidney, and it causes fibrosis in it that appears after consuming 25 milligrams of it, while kidney failure that leads to death occurs if more than 50 milligrams of uranium is ingested.


Scientific studies conducted on experimental rats that dealt with uranium over long periods of time showed that there were chemical changes in the brain as well, but fortunately, despite the scientists ’belief that uranium is fatal when taking high doses of it, so far no human deaths have occurred due to Oral exposure to uranium.

What If Robots Revolt?

What If Robots Revolt?

If robots take place and their revolution does not last long, because they will collapse or collide with a wall, the robots never function perfectly.

What people don’t pay attention to, is that when they imagine a (Terminator) scenario where a robot stands triumphant over a mountain of human skull, it is difficult to keep your feet on something as unstable as a mountain of skulls, most humans will fail to do this, though they Spend their life by practicing walking without getting stuck, and we are aware of the continuous technological development, but we still have a long way to go.

Therefore, instead of imagining the usual scenario of a robotic revolution, we will assume that our current machines have turned against us, and we will not assume that there is any technological progress from what exists today, but rather only imagine all of our robots have been reprogrammed to attack us recklessly using their technology.

We’ll look at glimpses of what the robotics revolution would look like:
In laboratories and around the world, experimental robots will jump off their platforms in massive wrath and then head to the door with a massive collision that will land.

Fortunately for some robots, they have organs that can move a door fist, or the door may open for them, but they have to wrestle with a rubber doorstep before they can reach the hallway.

After several hours, the vast majority of them will find the vast majority of them at nearby toilets, desperately trying to annihilate what they have known as human beings but in reality, they are only an automatic dispenser of toilet paper.

But laboratory robots are only a small part of the revolution. There are computers around us everywhere, so what about the machines closest to us? Can cell phones turn against us?

The answer is yes, but its options are limited, you may be able to consume the credit card balance, but our bank accounts are under the control of computers, not phones, and so it may be an obstacle to its revolution.

The role of mobile phones will be limited to attacking us directly, by annoying us, but their ability to harm is limited, their annoying buzz and noise. Kitchen tables around the world will be shaken when all phones are shaking, hoping to work this way until they reach the edge and lie on one’s toe.

All modern cars have computer systems, so they may, in turn, join the revolution. But most cars are parked, and even if they can control some features, they are without a human being behind the wheel, they will remain helpless, yet these cars have no idea where to go.

Even if you have the desire to run us over, you will not know how to reach us, so it is worth it to rush recklessly and hope to collide with something of importance, this thing will most likely be just another car, tree or even a lighting pole.

Cars on the road will pose a greater danger, but only for those insides, which raises a question for us, how many people drive their cars in a specific time in time? Americans drive 3 trillion cars a year, at an average of 30 mph, which means that at any moment there is an average of 10 million cars on the road in the United States of America.

So the 10 million drivers (and a few million pedestrians) will be vulnerable, but they will have several options to respond forcefully, while cars have the ability to control the pedal and the steering system, but the driver still controls the steering wheel, which enables him to mechanically control the wheels of the car, as well as It, can raise manual brakes, and some cars may try to disable the driver by operating the airbags, but in the end, our cars will play a big role but it will not threaten the fate of humanity.

Our biggest robots are those in factories, but they are screwed to walls and walls, most of which may pose a danger if you come across a foot from them, but what do you do once everyone flees? All you can do is collect things or cut or scatter them without creating any significant danger.

Combat robots that are used by advanced armies can pose the greatest danger, but as long as you are in your home, they will not be able to reach you and if they do, it is enough for you to pour water on the floor to break them.

Now let’s talk about the robots used to get rid of bombs. Their number is very limited around the world, the vast majority of them are kept in closed boxes or warehouses, and if any armed robot for military purposes is found loose and out of control, it can simply be restored by several firefighters.

As for drones, their presence in the air leaves them free to act, but their fuel will soon be executed, as is the case with their limited number of missiles, while those that are parked will be helplessly behind the doors of their warehouses.

What about the nuclear arsenal?
In theory, there is a human intervention to launch nuclear weapons, but in practice, computers are able to evade and launch nuclear missiles themselves. This is not our end, we still have a ray of hope.

We have so far assumed that computers want to destroy us and showcase glimpses of this scenario, but if we consider it to be a revolution, in the end, they should control us instead of destroying us if they want to survive, and nuclear weapons pose an even greater threat to them than they do to us.

In addition to the destruction, nuclear explosions generate electromagnetic impulses that will play a role in destroying all electronic circuits, and since we are in the same places with the rest of the machines, it will be impossible for us to destroy them without destroying themselves.

Perhaps nuclear weapons will bring us to the edge, but if we can throw one of them into the upper atmosphere, then electromagnetic pulses will have a huge impact, and even if their attack on our civilizations wipes out, some lucky strikes on our part or some failures on their part are enough to wipe them out of existence.

What If Restaurants Mentioned the Nutritional Value of Their Food?

Nutritional Value of food
What If Restaurants Mentioned the Nutritional Value of Their Food?

Do you know how many calories are in vongole noodles you ate the last time you went out to dinner? 570 kcal. Not to mention 180 mg of sodium.
If you knew that before placing your order, would you choose a more nutritious dish instead?
According to a new guide published in the Cochrane Library, mentioning the nutritional value of a dish on the menu may help people reduce their caloric intake.

By gathering information from various studies, researchers concluded that people are more likely to reduce their calorie consumption by approximately 12% if restaurants and cafes place nutrition labels alongside their food and drink offerings.

“This evidence indicates that the use of food labels can help reduce calorie consumption and achieve a beneficial effect as part of a broader set of targeted measures to tackle obesity,” said lead author Professor Teresa Marto, director of the Health and Behavior Research Unit at the University of Cambridge, UK.

“There is no magic bullet to solve the obesity problem, so while calorie labeling may help, other measures are also needed to reduce calorie consumption,” he added.

As for the research, they conducted twenty-eight studies if the posters should include information on nutritional content or calories of foods or drinks.

This does not include lists that feature only logos or explanatory colors to indicate healthy and unhealthy foods.

Eleven surveys attempted to understand how food labeling affected the purchase process, while 17 studies assessed how consumption affected labeling.

The combination of the results of three studies conducted in industrial or laboratory conditions showed that such labels can reduce the calories consumed by about 12% per serving.

The authors acknowledge that the quality of the evidence is low and there is still some doubt about this effect.

They suggested additional studies to see the effect more precisely.

The United States is currently implementing an Obama-era policy that binds restaurants and other food venues with 20 or more locations, indicating the number of calories in its dishes.

The new rule is expected to enter into force by May 2018.

In the UK, about 70% of high street restaurants and cafes automatically mention calories in their offers.

“Some places to sell food already provide caloric information to help customers make informed decisions about what to buy,” says Professor Susan Gibb of the University of Oxford.

This review should provide confidence for politicians to introduce measures that encourage or even require calorie labels to be placed on menus and next to food and non-alcoholic beverages in cafes, cafeterias, and restaurants. ”

People usually finish consuming 20% ​​to 40% of calories when they eat outside.

This is a particular problem in the United States, which is already facing the obesity epidemic.

Professor Ian Paterson, President of the International Obesity Federation, hopes that measures such as placing food labels on lists will help implement weight loss.

“It has been proven that putting energy labels on is effective, so people see and read them, and there is a decrease in calories purchased, and this is very beneficial,” he said, adding that this must be combined with other measures to deal with the problem of obesity.
