 मस्तिष्क के स्वास्थ्य के प्रति जन जागरूकता फैलाने के लिए हर साल 22 जुलाई को विश्व मस्तिष्क दिवस मनाया जाता है. वर्ल्ड ब्रेन डे हमारे शरीर के सबसे महत्वपूर्ण अंग को समर्पित है. वर्ल्ड ब्रेन डे मनाने की शुरुआत वर्ल्ड फेडरेशन ऑफ न्यूरोलॉजी द्वारा साल 2014 में हुई थी. अंतरराष्ट्रीय लीग अगेंस्ट एपिलेप्सी, वर्ल्ड स्ट्रोक ऑर्गेनाइजेशन और इंटरनेशनल हेडेक सोसायटी जैसी कई संस्थाएं साथ मिलकर मस्तिष्क संबंधी विकारों के बारे में जागरूकता बढ़ाने के लिए काम करती हैं, जिनका मकसद विश्व स्तर पर बेहतर न्यूरोलॉजिकल देखभाल को बढ़ावा देना है. >> वर्ल्ड ब्रेन डे का इतिहास << विश्व मस्तिष्क दिवस का इतिहास 22 जुलाई 1957 का है, जब द वर्ल्ड फेडरेशन ऑफ न्यूरोलॉजी की स्थापना की गई थी. इसी समिति ने विश्व मस्तिष्क दिवस मनाए जाने की वकालत की थी, जिसके बाद मस्तिष्क के स्वास्थ्य के प्रति जागरूकता फैलाने के लिए 22 जुलाई 2014 को पहली बार वर्ल्ड ब्रेन डे मनाया गया था. हालांकि 22 सितंबर 2013 को इस दिवस को मनाए जाने की घोषणा की गई थी. विश्व मस्तिष्क दिवस का मुख्य उद्देश्य सार्वजनिक जागरूकता को बढ़ाना और मस्...

 झंडा अंगीकरण दिवस हर वर्ष 22 जुलाई को मनाया जाता है। इस दिन अर्थात 22 जुलाई, 1947 को राष्ट्रीय ध्वज तिरंगे को भारत के संविधान द्वारा अपनाया ‘अंगीकृत’ गया था। ‘तिरंगा’ भारत का राष्ट्रीय ध्वज है, जो तीन रंगों से बना है इसलिए हम इसे तिरंगा कहते हैं। तिरंगे में सबसे ऊपर गहरा केसरिया, बीच में सफेद और सबसे नीचे गहरा हरा रंग बराबर अनुपात में है। ध्वज को साधारण भाषा में ‘झंडा’ भी कहा जाता है। झंडे की चौड़ाई और लंबाई का अनुपात 2ः3 है। सफेद पट्टी के केंद्र में गहरा नीले रंग का चक्र है, जिसका प्रारूप अशोक की राजधानी सारनाथ में स्थापित सिंह के शीर्षफलक के चक्र में दिखने वाले चक्र की भांति है। चक्र की परिधि लगभग सफेद पट्टी की चौड़ाई के बराबर है। चक्र में 24 तीलियां हैं। हमारे राष्ट्रीय ध्वज का इतिहास भी बहुत रोचक है। 20वीं सदी में जब हमारा देश ब्रिटिश सरकार की ग़ुलामी से मुक्ति पाने के लिए संघर्ष कर रहा था, तब स्वतंत्रता सेनानियों को एक ध्वज की ज़रूरत महसूस हुई क्योंकि ध्वज स्वतंत्रता की अभिव्यक्ति का प्रतीक रहा है। विजयी विश्व तिरंगा प्यारा, झण्डा ऊँचा रहे हमारा।

  Astronomers have announced the discovery of a new dwarf planet in our solar system, named 2017 OF201. Located far beyond Neptune, it orbits the sun every 25,000 years. Scientists have found evidence of a previously-undetected dwarf planet at the edge of the Solar System. The object, dubbed 2017 OF201, follows an extreme, oblong orbit, taking some 25,000 Earth years to circle the sun. The findings, which were confirmed by the International Astronomical Union's Minor Planet Center. but have not yet been peer reviewed, were published May 21 on the preprint server arXiv. 017 OF201 is a roughly spherical body about 435 miles (700 kilometers) in diameter, lurking beyond Neptune's orbit. A team of scientists spotted it while poring through archival data from the Blanco telescope in Chile and the Canada-France-Hawaii telescope based in Hawaii. The researchers tracked the object's motion across 19 sets of images spanning seven years. At its closest, the dwarf planet orbits at near...

  Clownfish have been shown to shrink in order to survive heat stress and avoid social conflict, Newcastle University research reveals. The fish, recognisable from the starring role in the film 'Finding Nemo', were studied by academics from the universities of Newcastle, Leeds and Boston, USA. The work was conducted in collaboration with Mahonia Na Dari Conservation and Research Centre, in Kimbe Bay, Papua New Guinea. The team measured the length of 134 clownfish every month for five months, and monitored the water temperature every 4-6 days, during a marine heatwave which are becoming increasingly common as a result of climate change. Publishing in the journal  Science Advances , they reveal the remarkable ability of clownfish to shrink, i.e. they can get shorter, in response to heat stress. Shrinking increased individuals' chances of surviving the heat stress event by as much as 78%. In a heart-warming discovery, they also show that coordination is important for clownfish...

Introduction The basic parts of a desktop computer are the computer case, monitor, keyboard, mouse, and power cord. Each part plays an important role whenever you use a computer. The computer case is the metal and plastic box that contains the main components of the computer, including the motherboard, central processing unit (CPU), and power supply. The front of the case usually has an On/Off button and one or more optical drives. Computer cases come in different shapes and sizes. A desktop case lies flat on a desk, and the monitor usually sits on top of it. A tower case is tall and sits next to the monitor or on the floor. All-in-one computers come with the internal components built into the monitor, which eliminates the need for a separate case. Monitor The monitor works with a video card, located inside the computer case, to display images and text on the screen. Most monitors have control buttons that allow you to change your monitor's display settings, and some monitors also...

An eclipse occurs when one heavenly body such as a moon or planet moves into the shadow of another heavenly body. Let’s learn about the two types of eclipses on Earth. What Is a Lunar Eclipse? The Moon moves in an orbit around Earth. At the same time, Earth orbits the Sun. Sometimes Earth moves between the Sun and the Moon. When this happens, Earth blocks the sunlight that normally is reflected by the Moon. (This sunlight is what causes the Moon to shine.) Instead of light hitting the Moon's surface, Earth's shadow falls on the Moon. This is an eclipse of the Moon, or a lunar eclipse. A lunar eclipse can occur only when the Moon is full. A lunar eclipse can be seen from Earth at night. There are two types of lunar eclipses: 1.Total lunar eclipse. 2.Partial lunar eclipse. A total lunar eclipse occurs when the Moon and the Sun are on exact opposite sides of Earth. Although the Moon is in Earth's shadow, some sunlight reaches the Moon. The sunlight passes through Earth...

His proposition that all species of life have descended from a common ancestor is now generally accepted and considered a fundamental concept in science.[ This brilliant 19th-century naturalist’s intense curiosity about the diversity of species led him to a new understanding of the world around us—and our place in it. Evidence collected during the five-year voyage of the HMS Beagle led to Darwin’s revolutionary theory that species adapt to different environments and change over time: all life, including humans, has evolved from a common ancestor through the process of natural selection. The new tools of genetics and molecular biology continue to build on Darwin’s radical ideas and refine our understanding of the mechanisms of evolution, which is essential to the study of life sciences. Happiest at home with his notebooks and his microscope, he shunned the public eye. Controversy made him ill. This brilliant observer of nature kept his most original and revolutionary idea under wraps...

AI coming of age is, um, coming! AI has been on the receiving end of massive financial investment over the last few years. According to Forbes, 80% of enterprises are now investing in it or are planning to expand AI investment if they already are. This influx of money has given rise to some serious innovation in deep learning. With all this cash flowing around, many tech experts believe AI will really "come of age" within the next few years. Internet at the speed of lightning The appetite for faster and faster internet connection is really pushing the technology forward. Businesses and private users are constantly demanding ever quicker response times and the industry is responding.

What are the latest technologies in computer science? According to sites like topuniversities.com, some of the latest technology areas of research include, but are not limited to: - - Big data analytics - Machine learning - Cloud computing - Computer-assisted education - Bioinformatics - Better cybersecurity

  Cyber security might not seem like an emerging technology, given that it has been around for a while, but it is evolving just as other technologies are. That’s in part because threats are constantly new. The malevolent hackers who are trying to illegally access data are not going to give up any time soon, and they will continue to find ways to get through even the toughest security measures. It’s also in part because new technology is being adapted to enhance security. As long as we have hackers,  Cyber Security   will remain a trending technology because it will constantly evolve to defend against those hackers.  As proof of the strong need for cybersecurity professionals, the number of cybersecurity jobs is growing three times faster than other tech jobs. According to Gartner, by 2025, 60% of organizations will use cybersecurity risk as a primary determinant in conducting third-party transactions and business engagements. You must note that however challenging th...

  Next remarkable technology trend is quantum computing , which is a form of computing that takes advantage of quantum phenomena like superposition and quantum entanglement. This amazing technology trend is also involved in preventing the spread of the coronavirus, and to develop potential vaccines, thanks to its ability to easily query, monitor, analyze and act on data, regardless of the source. Another field where quantum computing is finding applications is banking and finance, to manage credit risk, for high-frequency trading and fraud detection. Quantum computers are now a multitude times faster than regular computers and huge brands like Splunk, Honeywell, Microsoft, AWS, Google and many others are now involved in making innovations in the field of Quantum Computing. The revenues for the global quantum computing market are projected to surpass $2.5 billion by 2029 .  And to make a mark in this new trending technology, you need to have experience with quantum mechanics, l...

  The next technology trend that follows the IoT is 5G. Where 3G and 4G technologies have enabled us to browse the internet, use data driven services, increased bandwidths for streaming on Spotify or YouTube and so much more, 5G services are expected to revolutionize our lives. by enabling services that rely on advanced technologies like AR and VR, alongside cloud based gaming services like Google Stadia, NVidia GeForce Now and much more. It is expected to be used in factories, HD cameras that help improve safety and traffic management, smart grid control and smart retail too. Just about every telecom company like Verizon, Tmobile, Apple, Nokia Corp, QualComm, are now working on creating 5G applications. 5G Networks will cover 40% of the world by 2024. handling 25% of all mobile traffic data making it an emerging technology trend you must watch out for, and also save a spot in.

  Like AI and Machine Learning,   Robotic Process Automation, or RPA , is another technology that is automating jobs. RPA is the use of software to automate business processes such as interpreting applications, processing transactions, dealing with data, and even replying to emails. RPA automates repetitive tasks that people used to do.  Although Forrester Research estimates RPA automation will threaten the livelihood of  230 million or more  knowledge workers or approximately 9 percent of the global workforce, RPA is also creating new jobs while altering existing jobs. McKinsey finds that  less than 5 percent of occupations can be totally automated , but about 60 percent can be partially automated. For you as an IT professional looking to the future and trying to understand latest technology trends, RPA offers plenty of  career opportunities , including developer, project manager, business analyst, solution architect and consultant. And these jobs pay...

  Artificial Intelligence , or AI, has already received a lot of buzz in the past decade, but it continues to be one of the new  technology trends  because of its notable effects on how we live, work and play are only in the early stages. AI is already known for its superiority in image and speech recognition, navigation apps, smartphone personal assistants, ride-sharing apps and so much more. Other than that AI will be used further to analyze interactions to determine underlying connections and insights, to help predict demand for services like  hospitals  enabling authorities to make better decisions about resource utilization, and to detect the changing patterns of  customer behaviour  by analyzing data in near real-time, driving revenues and enhancing personalized experiences. The AI market will grow to a  $190 billion industry by 2025  with global spending on cognitive and AI systems reaching over  $57 billion in 2022.   W...

  We all use GPS every day; it has transformed our lives and many of our businesses. But while today’s GPS is accurate to within 5 to 10 meters, new hyper-accurate positioning technologies have accuracies within a few centimeters or millimeters. That’s opening up new possibilities, from landslide warnings to delivery robots and self-driving cars that can safely navigate streets. China’s BeiDou (Big Dipper) global navigation system was completed in June 2020 and is part of what’s making all this possible. It provides positioning accuracy of 1.5 to two meters to anyone in the world. Using ground-based augmentation, it can get down to millimeter-level accuracy. Meanwhile, GPS, which has been around since the early 1990s, is getting an upgrade: four new satellites for GPS III launched in November and more are expected in orbit by 2023. 

  Technology companies have proven to be poor stewards of our personal data. Our information has been leaked, hacked, and sold and resold more times than most of us can count. Maybe the problem isn’t with us, but with the model of privacy to which we’ve long adhered—one in which we, as individuals, are primarily responsible for managing and protecting our own privacy. Data trusts offer one alternative approach that some governments are starting to explore. A data trust is a legal entity that collects and manages people’s personal data on their behalf. Though the structure and function of these trusts are still being defined, and many questions remain, data trusts are notable for offering a potential solution to long-standing problems in privacy and security.

  We got very lucky. The two most effective vaccines against the coronavirus are based on messenger RNA, a technology that has been in the works for 20 years. When the covid-19 pandemic began last January, scientists at several biotech companies were quick to turn to mRNA as a way to create potential vaccines; in late December 2020, at a time when more than 1.5 million had died from covid-19 worldwide, the vaccines were approved in the US, marking the beginning of the end of the pandemic. The new covid vaccines are based on a technology never before used in therapeutics, and it could transform medicine, leading to vaccines against various infectious diseases, including malaria. And if this coronavirus keeps mutating, mRNA vaccines can be easily and quickly modified. Messenger RNA also holds great promise as the basis for cheap gene fixes to sickle-cell disease and HIV. Also in the works: using mRNA to help the body fight off cancers.
