हमसे बेहतर था आदिमानव

Technical Mechzone

गुफाओं में रहने वाले आदिमानव आखिर कैसे थे. आधुनिक विज्ञान के लिए यह सवाल आज भी पहेली है. पर इस बारे में खोज कर रहे वैज्ञानिकों का कहना है कि बीस लाख साल पहले धरती पर रहने वाले लोग हमसे अच्छी खुराक लेते थे.

लंबे वक्त तक यह माना जाता रहा कि गुफा में रहने वाले मानव सिर्फ मांस खाते थे. लेकिन अब यह भ्रम साबित हो रहा है. वैज्ञानिकों का कहना है कि पाषाण युग के इंसान फल, जड़ें, फलों के गूदे और मांस खाते थे. वैज्ञानिकों की एक रिसर्च टीम कहती है कि अगर गुफा मानव की खुराक का हिसाब मिल जाए, तो 21वीं सदी के इंसान की कई तकलीफें दूर हो जाएंगी. पौष्टिकता के आधार पर आहार और डाइट की सही पहचान हो सकेगी.

25 लाख साल पहले से लेकर 12,000 साल पहले के इस दौर में न आलू था, न ब्रेड थी. दूध का भी अता पता नहीं था. आज इन्हें मुख्य आहार माना जाता है. कृषि की शुरुआत को गुफा मानव के युग के बाद आज से करीब 10 हजार साल पहले हुई. ऐसे में यह सवाल उठ रहा है कि किसकी डाइट बेहतर है. आदम इंसान की या हमारी. शरीर, कद काठी, शारीरिक और मानसिक स्वास्थ्य इशारा करता है कि गुफा में रहने वाले हमसे ज्यादा सेहतमंद थे.

यूनीलीवर कंपनी के लिए शोध की अगुवाई कर रहे वैज्ञानिक डॉक्टर मार्क बेरी कहते हैं कि उनका उद्देश्य आज के लोगों के लिए सेहतमंद खुराक तैयार करना है. वह कहते हैं, “पाषाण युग के आहार में कई तरह के पौधे शामिल थे. आज हम एक दिन ज्यादा से ज्यादा एक सब्जी या पांच फल खा लेते हैं. वे लोग एक दिन में 20 से 25 प्रकार की साग सब्जी खाया करते थे.”



आज हम फसलें उगाते हैं और वह हमारे भोजन का अहम हिस्सा हैं. वहीं शताब्दियों पुराने इंसान कम कार्बोहाइड्रेट, कम वसा वाला खाना खाते थे. वह ज्यादा से ज्यादा साग सब्जियां खाते थे. अब सवाल उठता है कि स्वस्थ्य आहार कौन सा है. लंदन यूनिवर्सिटी में वंशानुगत बदलावों के प्रोफेसर मार्क थोमस कहते हैं कि गुफा मानव की डाइट ज्यादा बेहतर थी. पुराने शोध बताते हैं कि पत्थरों के सहारे अपनी रक्षा करने वाले गुफा मानवों को आहार की अधिकता संबंधी बीमारियां बहुत कम होती थी. उन्हें दो तरह की डायबिटीज नहीं थी, मोटापे का तो अता पता ही नहीं था. वैज्ञानिक दूध का उदाहरण देते हैं.


मार्क थोमास कहते हैं, “धीरे धीरे डाइट में कई बदलाव हुए. कई चीजें नई आई और कई गुम हो गई. दूध का ही उदाहरण ले लीजिए. 10 हजार

25 लाख साल पहले से लेकर 12,000 साल पहले के इस दौर में न आलू था, न ब्रेड थी. दूध का भी अता पता नहीं था. आज इन्हें मुख्य आहार माना जाता है. कृषि की शुरुआत को गुफा मानव के युग के बाद आज से करीब 10 हजार साल पहले हुई. ऐसे में यह सवाल उठ रहा है कि किसकी डाइट बेहतर है. आदम इंसान की या हमारी. शरीर, कद काठी, शारीरिक और मानसिक स्वास्थ्य इशारा करता है कि गुफा में रहने वाले हमसे ज्यादा सेहतमंद थे.

आजकल ऐसे खाते पीते लोगों की कमी नहीं
साल पहले इंसान ने दूध खोजा. पहले हम दूध को पचा नहीं पाते थे. लेकिन अब यह चीज आदत में ढल गई है. अब हम 100 फीसदी दूध या उससे बनी चीजें खाने पीने लगे हैं.” वैज्ञानिकों के मुताबिक आदिमानव जिस तरह की साग सब्जियां खाते थे, उससे हमारा खाना एक दम अलग हो चुका है. आहार संबंधी मामलों की एक और विशेषज्ञ प्रोफेसर मोनिक सिमंड्स कहती हैं, “कृषि के विकास का मॉडल पैसा कमाने पर आधारित है. पौष्टिक आहार पैदा करने के बजाय अब ऐसी फसलों की पैदावार की जा रही है जिनका अंतरराष्ट्रीय बाजार है…गेहूं इसकी का उदाहरण है.”


इस बात पर वैज्ञानिक एक मत हैं कि मौजूदा दौर में इंसान अनाज पर ज्यादा निर्भर हो गया है. अनाज की कई किस्में बाजार हैं. लेकिन शोधकर्ताओं को अफसोस है कि असली पौधे और उसके गुण इस बदलाव की भेंट चढ़ रहे हैं. शोध करने वालों का सुझाव है कि लोगों को चीनी और अति कार्बोहाइट्रेट वाले आहार से बचना चाहिए. उनकी जगह ऐसी चीजों का इस्तेमाल करना चाहिए जिन्हें अनदेखा किया जा रहा है.


धीरे धीरे यह बात साफ होने लगी है कि खाने पीने की इन बदली आदतों ने कई नई और घातक बीमारियों को भी जन्म दिया है. यह भी एक वजह है कि आज का इंसान अपने पूर्वजों की तुलना में शारीरिक रुप से कमजोर हो चुका है. इसका प्रमाण देने के लिए कुछ वैज्ञानिक आदिवासियों का अध्ययन कर रहे हैं. अब भी पुराने तरीके से रहे रहे दुनिया भर के कई कबीलों में आंख, दांत, गले, दिल और फेफड़े की बीमारियां न के बराबर हैं. उनके अध्ययन के आधार पर कहा जा रहा है कि हमें गाजर, अंडे, चिकन, रसीले फल, बादाम, मूली, शलजम और अखरोट जैसी चीजें ज्यादा खानी चाहिए. शुरुआत में हमारे पाचन तंत्र को एक बदलाव से गुजरना होगा, लेकिन देर सबेर इस आहार का अच्छा असर सेहत पर पड़ने लगेगा.

NASA releases first audio from Mars, video of Perseverance rover landing

Technical Mechzone

Justin Maki, NASA Perservere imaging scientist and instrument operations team chief, reveals a full panorama the rover captured from the surface of Mars

The video clip showed the deployment of the parachute and the rover’s touchdown on the surface of the Red Planet

The U.S. space agency NASA on Monday released the first audio from Mars, a faint crackling recording of a gust of wind captured by the Perseverance rover

NASA also released the first video of last week’s landing of the rover, which is on a mission to search for signs of past life on the Red Planet.

A microphone did not work during the rover’s descent to the surface, but it was able to capture audio once it landed on Mars.

NASA engineers played a 60-second recording

What you hear there 10 seconds in is an actual wind gust on the surface of Mars picked up by the microphone and sent back to us here on Earth,” said Dave Gruel, lead engineer for the camera and microphone system on Perseverance.

The high-definition video clip, lasting three minutes and 25 seconds, shows the deployment of a red-and-white parachute with a 70.5-foot-wide (21.5-meter-wide) canopy.

It shows the heat shield dropping away after protecting Perseverance during its entry into the Martian atmosphere and the rover’s touchdown in a cloud of dust in the Jezero Crater just north of the Red Planet’s equator.

“This is the first time we’ve ever been able to capture an event like the landing on Mars,” said Michael Watkins, director of NASA’s Jet Propulsion Laboratory, which is managing the mission.

“These are really amazing videos,” Mr. Watkins said. “We binge-watched them all weekend.”

Thomas Zurbuchen, NASA’s associate administrator for science, said the video of Perseverance’s descent is “the closest you can get to landing on Mars without putting on a pressure suit.”

Perseverance is healthy’
Jessica Samuels, Perseverance’s surface mission manager, said the rover was operating as expected so far and engineers were conducting an intensive check of its systems and instruments.


“I am happy to report that Perseverance is healthy and is continuing with activities as we have been planning them,” Ms. Samuels said.

She said the team was preparing for a flight by the rover’s small helicopter drone dubbed Ingenuity.

“The team is still evaluating,” she said. “We have not locked in a site yet.”

Ingenuity will attempt the first powered flight on another planet and will have to achieve lift in an atmosphere that is just one percent the density of Earth’s.


Perseverance was launched on July 30, 2020 and landed on the surface of Mars on Thursday.

Its prime mission will last just over two years but it is likely to remain operational well beyond that. Its predecessor Curiosity is still functioning eight years after landing on Mars.

Over the coming years, Perseverance will attempt to collect 30 rock and soil samples in sealed tubes to be sent back to Earth sometime in the 2030s for lab analysis.


About the size of an SUV, the craft weighs a ton, is equipped with a seven-foot-long robotic arm, has 19 cameras, two microphones and a suite of cutting-edge instruments.

Mars was warmer and wetter in its distant past, and while previous exploration has determined the planet was habitable, Perseverance is tasked with determining whether it was actually inhabited.

It will begin drilling its first samples in summer, and along the way it will deploy new instruments to scan for organic matter, map chemical composition and zap rocks with a laser to study the vapor.


One experiment involves an instrument that can convert oxygen from Mars’ primarily carbon dioxide atmosphere, much like a plant.

The idea is that humans eventually won’t need to carry their own oxygen on hypothetical future trips, which is crucial for rocket fuel as well as for breathing.


The rover is only the fifth to set its wheels down on Mars. The feat was first accomplished in 1997, and all of them have been American.


The United States is preparing for an eventual human mission to the planet, though planning remains very preliminary.

India mulls Bitcoin ban, existing investors to get transition period

Technical Mechzone

India will go ahead with a complete ban on investment in cryptocurrencies, while providing existing investors a transition period to exit their holdings.



Cryptocurrency isn’t fiat currency backed by the Reserve Bank of India and its usage in all forms will be banned through the new law that will be introduced in Parliament.


This would include a ban on transacting directly via foreign exchanges.


Seven million investors hold cryptocurrencies in India worth more than one billion dollars. The ban won’t be enforced overnight and cryptocurrency investors will be given a transition period of three-to-six months after the implementation of the new law to liquidate their investments. The proposed ban — is part of a comprehensive bill on crypto and digital currencies. It may be introduced in the ongoing budget session of parliament.



Does this mean the end of the road for cryptocurrencies in India?

Not really, the bill may include certain exceptions. They could allow the promotion of the underlying technology. Like block chain, the decentralized digital ledger.


That drives — all types of cryptocurrencies.

An exception like this could provide the legal framework for the reserve bank of India to launch its official digital currency. China has a similar regulatory regime. It effectively banned trading and usage of cryptocurrencies in 2017.


Crypto exchanges were shut down. Last year; Beijing began testing its own digital currency in four cities. India’s move to regulate digital cash comes at a time — when the world is increasingly adopting it.

MasterCard and Visa have opened their payments network for some cryptocurrencies.


Customers using these platforms can now pay or accept money through crypto. Recently, auto giant Tesla made a big bet on bitcoin.

The company bought more 1.5 billion dollars worth of bitcoin.


It also allowed customers to pay through bitcoin for its products. Cryptocurrencies are now part of the mainstream global financial system.

India cannot afford to ignore this shift but it needs a legal framework first.

Bitcoin hits $40,000 for first time, but sharp drop expected

Technical Mechzone

Increased demand from institutional, corporate, and more recently retail investors has powered bitcoin’s surge this year, attracted by the prospect of quick gains in a world of ultra-low yields and negative interest rates

Bitcoin topped $40,000 for the first time on Thursday, as it continues a rally that has seen the digital currency climb more than 700% from a March 12 closing low. Increased demand from institutional, corporate, and more recently retail investors has powered bitcoin’s surge this year, attracted by the prospect of quick gains in a world of ultra-low yields and negative interest rates.



The world’s most popular cryptocurrency climbed as high as $40,402.46 and was last up 6.1% at $39,100. It crossed $30,000 for the first time on Jan. 2 and $20,000 on Dec. 16. Smaller coins ethereum, the second largest in terms of market capitalization, and XRP, the fourth biggest, gained 1.8% at $1,231 and 31% at 32 US cents, respectively. Both currencies often move in tandem with bitcoin.



Some investors viewed bitcoin as a hedge against inflation amid enormous monetary stimulus aimed at battling the economic devastation caused by COVID-19. Market participants though warned a correction could be in the cards after a scorching rally.

“While further growth is inevitable, investors should not expect this to move in a straight line,” said Gavin Smith, chief executive officer of cryptocurrency consortium, Panxora Group. “The reality is that bitcoin is far from being a magic money tree, nor is it free from downward price swings. In fact, we can expect dips as sharp as 25% at times as investors periodically withdraw profits,” he added.


Bitcoins surge happened as the market cap for the entire cryptocurrency sector topped $1 trillion on Thursday, according to data trackers CoinMarketCap and CoinGecko. Glassnode, which provides insight on blockchain data, noted that retail interest in bitcoin has increased the last few weeks, with the number of bitcoin addresses or wallets holding a “non-zero amount” of the virtual currency reaching an all-time high of more than 33 million.


The information provider also said while interest in bitcoin and news coverage have grown, it is far from being in bubble territory. The number of daily new bitcoins has still not reached 2017 levels, Glassnode said, suggesting the currency is experiencing strong organic growth in adoption, but not the sort of “viral growth typical of a bubble.”

“Should I sell my cryptocurrencies?” and other questions answered on India’s proposed Crypto Ban bill

Technical Mechzone

* With the cryptocurrency bill looming large, consumers have been worried about their investments in cryptocurrencies like Bitcoin, Ethereum and others.

* We spoke to industry sources and exchanges to answer your questions, and help you understand if you should sell your Bitcoin and Ethereum investments.

* One of the key takeaways is that you should not panic.

* Read on to find out what you should do in case cryptocurrencies are banned.

One of the biggest questions in the minds of Indians holding cryptocurrencies is if they should sell their crypto investments before the Indian government bans them.

It is not an easy question to answer as there is little information from the government in this regard as of now. If you are panicking about your investments in Bitcoin, Ethereum, dogecoin and other cryptocurrencies, we are here to answer your questions.

Should I sell my cryptocurrencies?

Don’t panic.
Panic selling could prove to be counterproductive, especially since we don’t have enough information about the bill.
“Cryptocurrency holders in India should not panic. They should wait for the government to reveal all the details about what is being banned or not, and then take a decision accordingly,” said Nischal Shetty, co-founder of WazirX.
“Consumers need not panic and sell their crypto investments. CoinDCX has put in safeguard measures to ensure investors are protected, and we have the liquidity to help consumers liquidate their investments if they want to,” said Sumit Gupta, co-founder and CEO of CoinDCX.

“Consumers who are holding cryptocurrencies should not sell their investments in haste. The information in the public domain is incomplete, the details are still not finalised and ban may not materialize,” said Arjun Vijay, co-founder of Giottus Cryptocurrency Exchange”.

What happens if the government bans cryptocurrencies?

The government will likely give investors some time to liquidate their cryptocurrency holdings, so you should not worry about it right now.

“Even if the government bans cryptocurrencies, it will likely give some time to Indian investors to liquidate their assets,” Vijay further added”.

Will the government ban holding cryptocurrencies in foreign countries?

The details are not available right now, so it is suggested that you wait and watch for official information from the government.

Can I invest in cryptocurrencies via the Liberalised Remittance Scheme?

It might be possible to invest in foreign countries taking advantage of the Liberalised Remittance Scheme that allows resident individuals in India to invest up to $2,50,000.
However, in view of absence of details about the crypto ban, you should adopt a wait and watch approach.

Will banks freeze my account if I invest in cryptocurrencies? This is unlikely as your bank account and cryptocurrency investments are not related.

Will I be able to withdraw money from cryptocurrencies into my bank account?

As things stand right now, there is no restriction on selling cryptocurrencies and withdrawing those funds into your bank account. Even if the government bans cryptocurrencies, it is likely to give some time to investors to liquidate their assets.
“Consumers need not worry about cashing out their investments and receiving money in their bank accounts,” Gupta added, assuring that your money will not go down the drain. According to Shetty, millions of Indians hold over INR 10,000 crore in total in various forms in cryptocurrency investments. The government will give them a way out even if it bans cryptocurrency trading.

Indian Government Prepares to Fast Track Crypto Bill — Plans to Introduce Cryptocurrency Law in a Month: Report…..

Technical Mechzone

The Indian government is reportedly considering taking “the ordinance route” to quickly pass the cryptocurrency bill. “The government is of the firm view that they want to introduce the law within a month of clearance of the ordinance,” a local news outlet detailed.

Indian Government Seeks to Quickly Pass Crypto Bill

All eyes are on what the government of India will do with the cryptocurrency bill that is listed to be introduced in the current session of parliament. The bill seeks to ban cryptocurrencies while creating a framework for the official digital currency to be issued by the central bank, the Reserve Bank of India (RBI).

On Friday, CNBC-TV18 reported that “The government may take the ordinance route to pass the Cryptocurrency and Regulation of Official Digital Currency Bill,” citing unnamed sources. The news outlet elaborated:

The PMO, Finance Ministry, and Cabinet

The PMO, Finance Ministry, and Cabinet Secretariat have started preparing the draft details of the ordinance. The government is of the firm view that they want to introduce the law within a month of clearance of the ordinance

“They want this bill to be cleared as soon as possible,” reporter Timsy Jaipuria noted. She added that “the cabinet is understood to have given clearance to this particular proposal that this bill can be introduced via an ordinance route in its last meeting which was held on Feb. 3.”

Ordinances are promulgated by the president of India on the recommendation of the Union Cabinet. They have the same effect as an Act of Parliament. Ordinances can only be issued when Parliament is not in session, enabling the government to take immediate legislative action. The current Budget session began on Jan. 29 and will end on April 8. It is held in two phases; the first phase will end on Feb. 13 and the second will start on March 8.

The cryptocurrency bill could resemble the one drafted by an interministerial committee (IMC) headed by former Finance Secretary Subhash Chandra Garg, who has now resigned from the government. Recently, the Minister of State for Finance Anurag Thakur answered some crypto questions in Rajya Sabha, the upper house of India’s parliament, clarifying the government’s stance on cryptocurrency and the digital rupee.

There are still many unanswered questions about the bill the government is planning to introduce and many are just waiting for the bill to become public. Meanwhile, the Indian crypto industry has launched a campaign to convince the government not to impose a ban on cryptocurrencies.

There is a way to go to the black hole, but it is not possible to come back ‘!!!!!!!!!!!!!!

Technical Mechzone

Two physicists have figured out the conditions necessary to enter the black hole. Black holes are so mysterious that scientists are very keen to know about them. Scientists say that going to a black hole would be a one-way trip, because if the light could also come out from the black hole, then it is useless to predict the possibility of a human coming out. Small black holes do not rotate and the radius of their event horizon is very low. This is the place, after which nothing comes back.

An event horizon means that the event horizon is a boundary beyond which the events beyond it cannot have any effect on the universe outside its boundary, nor can any person sitting outside its boundary know what is beyond the boundary. Used to be.

Here the effect of gravity is very high. Apart from this, the radius of the event horizon of the second massive black hole is 7.3 lakh miles. There is a difference of thousands of billion times in gravity between the center of both and the event horizon. If a star-related object crosses the black hole’s event horizon, it undergoes a process of sphagatification.
Sphagetification is the process by which (in some theories) an object falling into a black hole will be separated or ripped off by gravitational forces. In this, every molecule of its body is pulled by a long strand. This happens because the gravity at one point in space time is much higher than the other point. When this happens, it is impossible to survive in a black hole.

However, if a person falls into a massive black hole, he will be in freefall and there will not be spaghettification. The reason behind this is that the distance between the black hole from the event horizon is much more.

Goldman Sachs’s Rahmani strikes warning over Bitcoin value

Technical Mechzone

The wild swings in the price of Bitcoin prove it’s not a real unit of value, though blockchain technology “is here to stay,” according to Goldman Sachs Group Inc.’s Sharmin Mossavar-Rahmani.

Something with a long-term volatility of 80% can’t be considered a medium of exchange,” said Rahmani, head of the investment-strategy group for the bank’s consumer and investment-management division.
Just because everybody piles into into an idea and talks it up doesn’t mean it’s a store of value,” she said during a briefing Wednesday on the group’s 2021 outlook, comparing the cryptocurrency’s spikes to the recent run-up in GameStop Corp.

Bitcoin surged to a record close of almost $41,000 in early January, but has since dropped back to about $37,000.

Rahmani’s skepticism about Bitcoin’s intrinsic value echoes that of European Central Bank governing council member Gabriel Makhlouf, who said last month Bitcoin investors should be prepared to “lose all their money.” Still, the cryptocurrency has plenty of high-profile proponents.


Paul Tudor Jones bought some as a hedge against central bank and government action, while Mike Novogratz and Alan Howard have both invested hundreds of millions of dollars in Bitcoin and other digital currencies. Bridgewater Associates founder Ray Dalio has called it “one hell of an invention” and an alternative, gold-like asset.
Rahmani drew a distinction between Bitcoin and blockchain technology, the public, mostly anonymous ledger that records all the currency’s transactions. That technology could facilitate the smoother flow of global assets and will become part of the financial infrastructure, she said.

Despite doubters on Wall Street, the unceasing buzz over Bitcoin is leading more banks to develop cryptocurrency products for clients. JPMorgan Chase & Co. launched its own digital currency last year and Fidelity Investments started a Bitcoin-only fund. Even Goldman Sachs may be joining the party. The bank issued a request for information to at least one crypto custody player at the end of 2020, website CoinDesk reported in January.
