Privacy-focused search engine DuckDuckGo has slammed the new ad tracking method by Google, saying it is bad for privacy and puts the users in a group based on their browsing history, and any website can get that group ID to target and fingerprint them.

Google has announced FLoC (Federated Learning of Cohorts) technology to provide a more privacy-focused way to track users and serve ads to them.
The company will put FLoC in Chrome and automatically turned it on for millions of users.

According to its rival DuckDuckGo that has surpassed 100 million daily search queries, if you’re a Google Chrome user, you might be surprised to learn that you could have been entered automatically into Google’s new tracking method.
“It groups you based on your interests and demographics, derived from your browsing history, to enable creepy advertising and other content targeting without third-party cookies,” the company said in a statement on Friday.
“After a short trial period, Google decided not to make this new tracking method a user choice and instead started automatically including millions in the scheme. If you’re reading this in Chrome while logged in to a Google account, yes, that likely means you too, and if not now, then eventually,” DuckDuckGo claimed.

It then urged people to block FLoC’s tracking and protect their privacy.
“Don’t use Google Chrome! Right now FLoC is only in Google Chrome, and no other browser vendor has expressed an intention or even interest to implement it. There are various browsers that are free to download, and we recommend some in our guide to Google alternatives,” it argued.
“On iOS or Android we suggest you use our own mobile browser, which offers best-in-class privacy protection by default when searching and browsing”.

The company said that in response to Google automatically turning on FLoC, it has enhanced the tracker blocking in its own Chrome extension to block FLoC interactions on websites.
“This is directly in line with the single purpose of our extension of protecting your privacy holistically as you use your browser. It’s privacy, simplified,” said DuckDuckGo.
The company is waiting for Google to approve its updated Chrome extension, and the update should appear in the Chrome Web Store soon.

“Don’t sync your history data with Chrome, or create a sync passphrase;
In Google Activity Controls, disable “Web & App Activity” or “Include Chrome history and activity from sites, apps, and devices that use Google services,” it advised.
The company said that while Google isn’t phasing out third-party cookies in Chrome until at least 2023, FLoC is already live today in 2021.

Websites can also take steps to protect the privacy of their users by opting out of FLoC, which would be applicable to all their visitors.
Launched in 2008, DuckDuckGo’s search engine is far behind Google but the latest controversies around user data privacy has helped it gain momentum like Telegram and Signal.
DuckDuckGo has been selected as the default search engine in the highly-secure chat platform Tor Browser, and is often the default search engine in the private browsing modes of several other browsers.

The average number of searches on Google per day reaches close to 50 million, while Google processes more than 3.5 billion search queries a da

मंगल ग्रह के आसमान में बना इंद्रधनुष!, नासा के मार्स रोवर ने खींंची कमाल की फोटो, जानें कैसे हुआ ये

नासा के परसिवरेंस मार्स रोवर ने लाल ग्रह के आसमान में इंद्रधनुष की कमाल की फोटो को अपने कैमरे में कैद किया है। हालांकि नासा का कहना है कि ये इंद्रधनुष नहीं बल्कि कैमरे के लैंस का कमाल है।

वाशिंगटन (एजेंसी)। मंगल पर भेजे गए नासा के मार्स रोवर परसिवरेंस ने वहां के आसमान में एक कमाल की फोटो खींची है। इसमें मंगल के आसमान में इंद्रधनुष बना हुआ दिखाई दे रहा है, जो कि बेहद खूबसूरत भी है। ये पहला मौका है जब किसी रोवर ने धरती से इतनी दूर इस तरह की कोई चीज को कैमरे में कैद किया है।

नासा की तरफ से इसकी जानकारी ट्वीट कर दी गई है। साथ ही कहा गया है कि बहुत लोगों का कह रहे हैं कि क्‍या ये लाल ग्रह पर इंद्रधनुष है। इसके जवाब में नासा ने कहा है कि नहीं। नासा के मुताबिक मंगल ग्रह पर इंद्रधनुष हो ही नहीं सकता है।



नासा का कहना है कि इंद्रधनुष रोशनी के रिफ्लेक्‍शन और पानी की छोटी-छोटी बूंदों से बनता है, लेकिन मंगल ग्रह पर न तो इतना पानी मौजूद नहीं है और न ही इस अवस्‍था में मौजूद है और यहां पर वातावरण में तरल पानी के लिहाज से यहां बेहद ठंडा है। नासा ने बताया है कि दरअसल, मंगल ग्रह के आसमान में दिखाई देने वाली ये इंद्रधनुषी छटा रोवर के कैमरे में लगे लैंस की एक चमक है।


आपको बता दें कि नासा का वातावरण बेहद सूखा है जहां पर वातावरण में करीब 95 फीसद तक टॉक्सिक कार्बनडाईऑक्‍साइड मौजूद है। इसके अलावा 4 फीसद में नाइट्रोजन और अरगोन है और एक फीसद ऑक्‍सीजन और वाटर वेपर है। इस तरह से केमिकल और फिजीकली मंगल ग्रह धरती से काफी अलग है।

नासा के मार्स रोवर द्वारा ली गई इस इमेज की बात करें तो ये 18 फरवरी को उस वक्‍त ली गई थी जब रोवर ने मंगल ग्रह की सतह को छुआ था। नासा की तरफ से एक बयान जारी कर इसकी जानकारी दी गई है।


नासा के सोलर सिस्‍टम एक्‍सप्‍लोरेशन के प्रोग्राम एग्‍जीक्‍यूटिव डेव लावेरी का कहना है कि तस्‍वीर में नजर आने वाले रंगों की लाइन की वजह लाल ग्रह के आसमान में छाई धूल भी हो सकती है जो सूरज की रोशनी में चमक रही है।

इसमें कुछ कमाल लैंस की चमकक का भी हो सकता है। उनके मुताबिक जिस वक्‍त ये तस्‍वीर ली गई उस वक्‍त रोवर उत्‍तर दिशा की तरफ था और मार्स सोलर समय के मुताबिक उस वक्‍त दोपहर के दो बजे थे। कैमरा उस वक्‍त दक्षिण की तरफ था।

इस लिहाज से ये एक बेहतर समय है जबकि रोशनी की चमक रोवर के कैमरे पर पड़ सकती है। हालांकि कुछ जानकारों का ये भी मानना है कि इस तरह की फोटो आने की एक वजह आइसबो भी हो सकती है जो मास्र के पोलर क्षेत्र में हैं।


गौरतलब है कि नासा का परसिवरेंस फरवरी में लाल ग्रह के जेजीरो क्रेटर में उतरा था। इसका काम यहां पर जीवन तलाश करना है। मंगल पर भेजा गया नासा का ये 5वां रोवर है। पहली बार नासा ने मंगल ग्रह पर एक हेलीकॉप्‍टर इंजेंवेनिटी भी भेजा है, जिसको फिलहाल इसकी सतह पर उतार दिया गया है। इसकी उड़ान के साथ ही नासा एक और इतिहास रचने के करीब पहुंच गया है। ये उड़ान संभवत: गुरुवार को होनी है।

Scientists discover ‘safest place’ to live in galaxy

Astronomers have found the safest place to live in the galaxy after much research.For this, scientists had to investigate the entire galaxy. Surprisingly, the planet we humans are living on.

अंतरिक्ष विज्ञानियों ने काफी रिसर्च के बाद आकाशगंगा में रहने के लिए सबसे सुरक्षित स्थान खोज लिया है. इसके लिए वैज्ञानिकों को पूरे आकाशगंगा की जांच करनी पड़ी. हैरानी की बात ये है कि हम इंसान जिस ग्रह पर रह रहे हैं, वो काफी ज्यादा सुरक्षित स्थान पर हैं. लेकिन अगर आप पिछले साल की कोरोना महामारी से ऊब कर किसी और ग्रह पर जाने की योजना बना रहे हैं तो यकीन मानिए आपके लिए आकाशगंगा का केंद्र सबसे ज्यादा सुरक्षित स्थान होगा.

इटली के इनसुब्रिया यूनिवर्सिटी (Insubria University) के अंतरिक्ष विज्ञानियों की टीम ने इस स्टडी को किया है. इस टीम के प्रमुख और एस्ट्रोनॉमर रिकॉर्डो स्पिनेली ने कहा कि अंतरिक्ष में हुए विस्फोट (Cosmic Explosion) की वजह से कई जीवों का अंत हो चुका है. अंतरिक्ष के विस्फोट यानी सुपरनोवा, गामा-किरणों का फूटना, उच्च-ऊर्जा वाले कणों का फैलना और रेडिएशन DNA को फाड़ सकते हैं, ये जीवन को खत्म कर सकते हैं.

इन खतरों से सुरक्षित स्थान को खोजना आसान नहीं था. आकाशगंगा में कई ऐसी जगहें हैं जो ऐसे खतरों से भरी पड़ी हैं. रिकॉर्डो कहते हैं कि ताकतवर कॉस्मिक एक्सप्लोशन को अनदेखा नहीं कर सकते. ये जीवन के अस्तित्व के लिए खतरा है. इन विस्फोटों की वजह से गैलेक्सी में जीवन का विकास बाधित हुआ है

रिकॉर्डो और उनकी टीम ने सबसे दो चीजें खोजी. सबसे खतरनाक और सबसे सुरक्षित स्थान. इसके लिए इन लोगों ने आकाशगंगा के 11 बिलियन साल पुराना इतिहास खंगाला. जिससे पता चला कि हम अभी आकाशगंगा में जहां रह रहे हैं वो सबसे सुरक्षित बेल्ट में आती है. जबकि करोड़ों साल पहले आकाशगंगा के निर्माण के समय इसका सबसे सुरक्षित स्थान इसका आखिरी छोर थे.

किसी ग्रह को रहने योग्य बनने के लिए जरूरी है वहां पर उसके तारे के साथ सामंजस्य हो. यानी सूरज से धरती को पर्याप्त गर्मी मिले. न कम न ज्यादा. इसके अलावा अंतरिक्ष से आने वाली मुसीबतों से ग्रह दूर रहे. जैसे- रेडिएशन, सुपरनोवा, गामा किरणों का बहाव, उच्च ऊर्जा वाले कण और सौर तूफान. इन सारे खतरों से फिलहाल धरती सुरक्षित है. इसलिए ऐसा कहा जा सकता है कि हम आकाशगंगा के सबसे सुरक्षित स्थानों में से एक में रह रहे हैं.

सुपरनोवा, गामा किरणों का विस्फोट, खतरनाक स्ट्रीम्स, उच्च-ऊर्जा वाले कण ये सारे प्रकाश की गति से बहते हैं. अगर इनके सामने किसी भी प्रकार का जीवन आता है तो ये उसे नष्ट कर देते हैं. इतना ही नहीं ऐसे ग्रहों को भी खत्म कर सकते हैं जिनपर जीवन है या वो निर्जीव ग्रह हैं. इसलिए वैज्ञानिकों को लगता है कि हमारे सौर मंडल में बाकी ग्रहों पर भी जीवन रहा होगा लेकिन वो इन्हीं वजहों से खत्म हो गया हो.

रिकॉर्डो कहते हैं कि अंतरिक्षीय विस्फोट के आसपास के ग्रहों पर तो जीवन का पूरा सफाया हो गया होगा. 45 करोड़ साल पहले ओर्डोविसियिन (Ordovician) नाम का एक ग्रह था, जिसे दूसरी धरती कहा जाता था. इस पर मास एक्सटिंक्शन (Ordovician Mass Extinction) यानी सामूहिक विनाश होने की वजह आसपास हुआ गामा-किरणों का विस्फोट रहा होगा. अब आकाशगंगा में इसके बचे हुए हिस्से ही मिलते हैं. धरती बच गई क्योंकि इसकी दूरी और सौरमंडल का प्रभाव इसे बचा ले गया.

वैज्ञानिकों ने जानलेवा रेडिएशन को लेकर भी मॉडल्स और नक्शे बनाए. पता चला कि शुरुआत में गैलेक्सी का अंदर वाला हिस्सा, जो कि 33 हजार प्रकाशवर्ष बड़ा था, वह रहने योग्य नहीं था. क्योंकि यहां पर ऐसे तारे थे जिनका रेडिएशन बेहद खतरनाक था. यहां विभिन्न प्रकार के विस्फोट होते रहते थे. लेकिन आकाशगंगा का बाहरी इलाका सुरक्षित था

600 करोड़ साल पहले हमारी आकाशगंगा का स्टर्लाइजेशन (Sterilization) यानी सफाई हो रही थी. जैसे-जैसे गैलेक्सी की उम्र होती चली गई, विस्फोट होने कम हो गए. आज की तारीख में आकाशगंगा के अंदर घेरा है जो इसके केंद्र से 6500 प्रकाशवर्ष की दूरी पर है. जबकि 600 करोड़ साल पहले ये घेरा 26 हजार प्रकाश वर्ष की दूरी पर था. आज भी 6500 प्रकाशवर्ष से लेकर 26 हजार प्रकाशवर्ष के बीच की दूरी आकाशगंगा में रहने के हिसाब से सबसे सुरक्षित है.

आकाशगंगा के केंद्र में सुपरनोवा और अन्य अंतरिक्षीय गतिविधियां होती रहती हैं. लेकिन बाहरी छोर पर ये कम हैं. अगर भविष्य की बात करें तो हमारी आकाशगंगा अब जीवन को पनपने का माहौल बना रही है. अब ऐसी घटनाएं नहीं हो रही हैं, जिससे पूरे के पूरे ग्रह खत्म हो जाएं. या उनपर बसा जीवन नष्ट हो जाए.

Sea Monster: 50 million years old sea devil’s genes found in human body, scientist shocked; Know what effect

Genetic codes of the body shape, sensory organisms, immune system of the organisms of the early days of the earth are still present in different organisms on the earth.The time mentioned in this study was that of Ediacaran Era. These creatures used to stick to the surface of the oceans. Used to dig and eat the sea surface.

New Delhi: The genes of the 50 million year old marine organism are still present in the human body. Significantly, these creatures lived in the ancient seas. It is seen like leaves, teardrops, rope curved Whereas most sea creatures of that time did not look like this. Scientists are calling it a sea devil. Let’s know what are these demonic creatures and how their genes came into the human body.

What study says

According to this study, the body size of the organisms of the early days of the earth, the sensory organisms, the genetic code of the immune system still exist in different organisms on the earth today.The time mentioned in this study was that of Ediacaran Era. These creatures used to stick to the surface of the oceans. Used to dig and eat the sea surface.


These are sea freaks

The specialty of these marine organisms was that they were called rangeomorphs.That is, for many years the scientist was confused about whether to call them leaf or jiva. It is called Satan the Devil because of the evil of changing its form. It is revealed that there are sea devil jeans inside humans.

These creatures were very mysterious

Scientists could not classify them due to the strangeness and different size of these organisms.Mary Droser, professor of geology at the University of California and Scott Irwin, research biologist at the National Museum of Natural History, Washington, along with Scott

These are four organisms – oval-looking Dickinsonia, tear drop-like Kimberella, uncharacteristically shaped tribrachidium and earthworms such as the earthworms.

Strange creatures

These four creatures had neither head nor feet. But they had some common features like the creatures of today. For example, three of these creatures were in equilibrium cemetery from left to right.Their bodies were divided into different parts. Today it is not possible that genetic makeup of these organisms can be done, but symmetry and division of body parts mix them with the existing organisms.

Extremely High Season Jeans

According to Scott, these four organisms had extremely high season jeans. They used to control their nervous system i.e. nervous system. That is, Regulatory Ge in them


What do these creatures do

This study has been published in Proceedings of the Royal Society B It has also been told that scientists have studied very complex genes that make up the nervous system and muscles. Such genes were present in these four marine organisms and are also found in today’s animals.

NASA’s Curiosity Rover sent selfie from Mars, showing rocky sight of red planet

Washington
NASA’s Curiosity Rover has started working on a rock on Mars since early March. It is named Mont Mercou.The 6-meter-high rock is taken by Rover in a selfie. In the selfie, the rover is seen in front of the rock and the new drill hole is also seen on Nontron, a sample rock. This is the 30th sample of the rover.

This selfie is made up of 60 photographs taken by Mars Hand Lens Imager (MAHLI). It is mounted on the rover’s robotic arm. These photos were mixed with 11 photos taken from Mastcam.Earlier, Rover’s Mastcam also took some panorama photos.

Curiosity transformed the sample into powder after taking it and kept it safe.With their help, the team will study the structure of the rock and try to find out how the history of Mars was. Mont Mercou is a place in France near the village named Nontron. On Mars, scientists found the clay mineral Nontronite which is found in Nontron. That is why this place was named after Nontron.

A few days ago Curiosity sent a video of Mars clouds. These views were captured in the cameras mounted on him.Eight new photos showed five-minute views from the navigation camera’s eye. They were seen moving like the clouds of the earth. These were shared by Scientist Paul Brynern of North Carolina State University.
