 An animal with a surprising "gun"

The pistol shrimp is a small animal, but it packs a powerful punch. It is the noisiest animal in the world, producing a sonic boom louder than a Concorde.

This shrimp closes its claw so fast that a bubble forms in the water, which immediately bursts, creating a loud sound. The shock reaches 230 decibels, louder than a gunshot.

When this bubble bursts, it produces a heat of 4,400 degrees Celsius (7,952 Fahrenheit) for a few moments, which is as hot as the surface of the sun, and it kills the prey instantly.

This amazing phenomenon is called "sonoluminescence." Sonoluminescence is the light produced when a bubble in a liquid bursts, stimulated by sound waves. The process also produces light and heat.

The complete process of sonoluminescence is still a mystery to scientists. Various theories such as hotspot bremsstrahlung and collision-induced radiation try to explain it. It is a fascinating and mysterious phenomenon that scientists are still trying to understand.


 ایک حیران کن "بندوق" رکھنے والا جانور

پسٹل شرمپ ایک چھوٹا سا جانور ہے مگر اس میں ایک زبردست طاقت چھپی ہے۔ یہ دنیا کا سب سے زیادہ شور پیدا کرنے والا جانور ہے، جو ایک سونک بوم پیدا کرتا ہے جو کونکورڈ طیارے سے بھی زیادہ زور دار ہوتا ہے۔

یہ جھینگر اپنے پنجے کو اتنی تیزی سے بند کرتا ہے کہ پانی میں ایک بلبلا بنتا ہے جو فوراً پھٹ جاتا ہے اور ایک زور دار آواز پیدا کرتا ہے۔ یہ جھٹکا 230 ڈیسی بیل تک پہنچتا ہے، جو بندوق کے فائر سے بھی زیادہ ہوتا ہے۔

یہ بلبلا جب پھٹتا ہے تو لمحوں کے لیے 4,400 ڈگری سینٹی گریڈ یعنی 7,952 فارن ہائیٹ کی حرارت پیدا کرتا ہے، جو سورج کی سطح جتنی گرم ہوتی ہے، اور یہ شکار کو فوراً مار دیتا ہے۔

اس حیران کن مظہر کو "سونولومینیسنس کہا جاتا ہے۔ سونولومینیسنس وہ روشنی ہے جو مائع میں بلبلے کے پھٹنے پر، آواز کی لہروں سے متاثر ہو کر پیدا ہوتی ہے۔ اس عمل میں روشنی اور حرارت بھی پیدا ہوتی ہے۔

سونولومینیسنس کا مکمل عمل ابھی تک سائنسدانوں کے لیے معمہ ہے۔ مختلف نظریات جیسے ہاٹ اسپاٹ بریمسسٹرالنگ اور کولیژن انڈیوسڈ ریڈی ایشن کی وضاحت کرنے کی کوشش کرتے ہیں۔ یہ ایک دلچسپ اور پراسرار مظہر ہے جسے سائنسدان اب بھی سمجھنے کی کوشش کر رہے ہیں

liquid water discovered on Mars

liquid water discovered on Mars This is the first clear evidence of liquid water, not just frozen ice, discovered on Mars. A groundbreaking discovery published in Science has confirmed that Mars once had liquid water, offering new insights into the planet’s climate and potential for supporting life.  Researchers analyzing data from NASA’s Curiosity rover identified ancient "wave ripples" in rocks at the Gale Crater region, dating back 3.7 billion years. These ripples, formed by wind and water, indicate the presence of a shallow, open-air lake about 2 meters (6.5 feet) deep.  The discovery highlights a time when Mars had a warmer climate and a thicker atmosphere capable of sustaining liquid water — a critical ingredient for life as we know it. This revelation has far-reaching implications for understanding Mars' habitability and planning future missions.  The presence of liquid water raises the possibility that microbial life once thrived on the planet. Additionally, remna...

A black diamond

A black diamond that is actually an apple? Of course, you have seen apples of various colors including green and red, but there is one region in the world where black apples grow. By the way, the color of this apple is deep violet, but it looks black, which is why it is called in English  (black diamond apple)  is called and it is found only in Tibet. The black diamond apple stands out from other apples due to its luxurious appeal and rarity and also arouses people's curiosity. The distinctive color of the black diamond apple is actually attributed to the unique geographical location of Ningchi, a small town nestled among the mountains in the Tibet Autonomous Region of China. Apples found at high altitudes are exposed to intense ultraviolet light during the day, causing significant temperature fluctuations. Such climatic conditions contribute to the production of the characteristic black color of the apple. Although the inside of the black diamond apple is like a regular apple...

Strong and secure shelters Switzerland is the only country in the world that can evacuate all its citizens (114%) to underground safe rooms, whenever an emergency occurs. There are more than 300,000 strong and secure shelters, all of which can shelter a total of 8.6 million people, compared to the country's current population of 8.3 million. Switzerland's security system is highly organized and prepared for all types of emergency situations, making it unique worldwide. The special feature of this system is that it is capable of sheltering not only every citizen but also additional persons, and its structure is based on the following features: 1. Number and capacity of underground shelters There are more than 300,000 shelters in Switzerland, most of which are underground and made of reinforced concrete. These shelters can provide protection to a total of 8.6 million people, compared to the country's current population of about 8.3 million. This means that space is reserved f...
