Based on attitude and climate conditions, the regions below 800 meters (26-25 feet) above sea level are suitable for dragon fruit cultivation. Dragon fruit While they are not very demanding in a specific soil type, pitahaya can have maximum growth and yield in well-drained, light soils (with a good amount of loamy sand) with slightly acidic pH (5.5-6.5) and rich in organic matter. Dragon fruit, like all succulents, is sensitive to water logging and suffers in soggy, wet soils. While it can be planted even in clay loam soil types, it will grow more poorly than in sandy or loamy soil. The reason is that clay soil is very heavy and holds too much water, and the roots of the dragon fruit can easily become waterlogged and rot in such conditions. In heavy, water-loggings soils, the grower can mix soil with sand or small stone gravel to facilitate drainage to avoid this problem. On the other hand, very sandy soils may require more frequent irrigations and fertilization with smaller amounts pe...

Science magic is a great way to introduce kids to scientific concepts in a fun and engaging way. Here are a few simple science magic tricks that kids will love: Click here for some videos: https://in.pinterest.com/pin/711498441153648432 Magic Balloon: Blow up a balloon and tie it off. Then, rub the balloon on your hair or a piece of fabric to create static electricity. Hold the balloon near a wall or ceiling and watch as it magically sticks. Explanation: Rubbing the balloon creates a static charge, which attracts the opposite charge in the wall or ceiling, causing the balloon to stick. Magic Pepper: Fill a bowl with water and sprinkle some pepper on top. Dip a finger into dish soap and then touch the surface of the water. The pepper will magically move away from your finger. Explanation: The dish soap reduces the surface tension of the water, causing the pepper to move away from the area with lower surface tension. Magic Egg: Place a raw egg into a glass or jar and cover it with vinega...

  NEWS 16 March 2023 GPT-4 company OpenAI this week unveiled  GPT-4 , the latest incarnation of the large language model that powers its popular chat bot ChatGPT. The company says GPT-4 contains big improvements — it has already stunned people with its ability to create human-like text and generate images and computer code from almost any a prompt. Researchers say these abilities have the potential to transform science — but some are frustrated that they cannot yet access the technology, its underlying code or information on how it was trained. That raises concern about the technology’s safety and makes it less useful for research, say scientists. One upgrade to GPT-4, released on 14 March, is that it can now handle images as well as text. And as a demonstration of its language prowess, Open AI, which is based in San Francisco, California, says that it passed the US bar legal exam with results in the ninetieth centile, compared with the tenth centile for the previous version o...

Antarctica      (Credit: Inside Science )       Antarctica is unlike anywhere else on Earth. It's the highest, driest, coldest and windiest continent on the planet. Its ice sheet is the largest ice store on Earth as well.      Despite the continent's extreme conditions, it's also a great natural laboratory -- which is why so many scientists brave the cold to work there. ( click here )      Huw Griffiths is a marine biogeographer who never thought he would visit the area but ended up exploring, studying and learning new things about the vast, remote land. He grew up near the beach and wouldn't have pictured himself studying marine biology in a completely opposite climate in Antarctica. But it's paid off, because he loved it and finds new species every time he visits!  

  Next-age Electrical Transmission Scientists this week announced advancement towards a superconductor material that could conduct electricity in everyday conditions. The breakthrough means a stunning transformation into any technology that uses electric energy. The breakthrough also means the opening of new possibilities for your phone, magnetically moving trains, and future fusion power plants. A peer-reviewed accounting of the findings was published on Wednesday in the Nature journal. The new superconductor consists of lutetium, a rare earth metal, and hydrogen with a little bit of nitrogen mixed in. It needs to be compressed to a pressure of 145,000 pounds per square inch before it gains its superconducting prowess. That is about 10 times the pressure that is exerted at the bottom of the ocean’s deepest trenches. A team of physicists led by Ranga Dias, a physicist from the University of Rochester in New York, claims it might have cracked it. The team demonstrated a...

  Air pollution speeds up bone loss in postmenopausal women, says study The effects were most evident on the lumbar spine, with nitrous oxides causing twice as damage to the area than seen with normal ageing, the scientists claimed. The study was done by scientists from Columbia University Mailman School of Public Health. And the findings have been published in the peer-reviewed journal eClinicalMedicine, part of The Lancet Discovery Science suite of open-access journals. This conclusion was drawn after researchers examined the bone scan of more than 9,000 women living in four different parts of the US. Each woman had done a bone scan thrice over a six-year period and then it was compared with the air they breathed. It was found that on average, air pollution accounted for a doubling of the speed of bone loss. The new research builds on previous work by the same group that looked at hospitalisation for fractures among more than 9 million people in the eastern US. This time, the tea...

what is life meaning Life is a complex and beautiful thing that can be both joyful and challenging. It is a journey full of ups and downs, successes and failures, and moments of great happiness and deep sorrow. Every person's experience of life is unique and shaped by their own thoughts, beliefs, and actions. At its core, life is about growth, learning, and connecting with others. We all have a purpose and a role to play in the world, and it is up to us to discover what that is and fulfill it to the best of our abilities. Along the way, we will face obstacles and setbacks, but these are opportunities for us to learn, grow, and become stronger. Ultimately, life is what we make of it. We have the power to create our own reality and shape our own destiny. By living with purpose, gratitude, and kindness, we can make the most of the time we have and leave a positive impact on the world around us.

Is The Sperm Race A Fairy Tale? sperm race      The term "sperm race" typically refers to the competition between individual sperm cells to fertilize an egg cell during sexual reproduction.      During intercourse, millions of sperm are released into the female reproductive tract, with the goal of reaching and fertilizing the egg that is released by the female's ovaries. The journey from the vagina to the fallopian tubes, where fertilization occurs, is long and treacherous, with many obstacles that sperm must overcome. Sperm must navigate through the acidic environment of the vagina, fight off the female immune system, and outcompete rival sperm from the male partner, among other challenges. The journey can take several hours, and only a small percentage of the sperm released will make it to the egg. Once the sperm reach the egg, they must penetrate the outer layer of the egg cell to fertilize it. Only one sperm can successfully fertilize the egg, and once...

Stop! Don’t Burn fallen Leaves Burn fallen leaves Reason:      Gardeners, sweepers and residents are openly seen burning dry and fallen leaves and adding to the air pollution in the already polluted city. It is a practice that is going unnoticed posing serious environmental hazards.      Burning of leaves leads to air pollution, health problems and fire hazards. Leaf smoke may also contain hazardous chemicals such as carbon monoxide, which can mix with haemoglobin in the bloodstream and reduce the amount of oxygen in the blood and lungs. Another noxious chemical commonly present in leaf smoke is benzo (a) pyrene, which has been shown to cause cancer in animals and is believed to be a major factor in lung cancer caused by cigarette smoke. Breathing leaf smoke can irritate eyes, nose and throat of healthy adults and can wreak havoc on small children and aggravate things for the elderly and people with asthma or other lung or heart diseases.    ...
