3D Printers and 4 ways

Seemed like it was just yesterday when 3D printers were the talk of the town, hyped to the maximum, the next big thing, a technological wonder that was poised to revolutionize our world like never before. However, the fire seems to have burned out pretty quickly as most now think that these 3D printers are only suitable for printing miniature action figures for geeks.

Yes, its is known that these machines can do a lot more than just print action figures, but do their boons far outweigh their bane. Here are some talking points on potential harmful consequences of using 3D printers:

1) Energy-Hogging – They consume about 100 times more energy to melt plastic and mold it than injection molding.

2) Air Emission – The emission of unhealthy toxins from burning of plastics resulting in environmental issues and health risks.

3) Plastic Reliance – When the world is moving towards a plastic free age, ironically, the devices is centered around the usage of plastic for printing purposes.

4) Manufacturing Impact – Introduction of these printers in the car or aviation manufacturing industries to replace the human element will result in loss of jobs for manual labor.
For every bad thing that can be said about anything, there can definitely be a good thing that can be said about it too. Let us see how 3D printers can help change the world for the better.

Changing the way rhinos are being poached:-
A San Francisco-based startup has come up with an interesting concept to curb the poaching of rhino horns. Coupling the usage of 3D printers and the advancements in biotechnology, they are attempting to fabricate rhino horns from not synthetic materials but organic matter, metals, minerals, proteins and in cases even actual rhino DNA. The idea is to sell these artificial rhino horns to the said poachers ( to cover the cost of printing it ) who then go on to sell them in various international markets to make money and feed their families. This way, the rhinos are left unharmed and the market eventually dies out.

Tracking poachers using turtle egg shells:-
Not as big as a rhino but just as endangered, turtles have a huge market for their goods. Turtle eggs are stolen and sold for huge money with one egg going for a whopping $150. Paso Pacifico, an environmental conservation organization has taken the initiative to safeguard these turtle eggs from being poached and sold. They proposed to use 3D printers to print fake eggs, equip them with GSM and mixing them with the real eggs so as to enable the authorities to track their movement and uncover the sellers and their markets.

Medicine and health care:-
While we are on the topic of turtles and their safety, here’s another usage of the 3D printer, that is soon to be adopted by almost all veterinary hospitals around the world.

The image displayed below is of Akut-3 a loggerhead sea turtle that got struck on the jaw by a boat’s propeller. It was rescued by an organization called Dekamer.
A CT Scan of his skull showed what needed to be done, and BTech Innovations a company that specializes in custom implants created this printed beak and jaw made out of titanium for the wounded turtle. Now, Akut-3 is swimming freely deep in the ocean with his almost perfect printed jaw.

Self Service Dentistry:-
From turtles onto humans, we go on to the case of one Mr. Amos Dudley, a digital design student from New Jersey who decided to implement all that he learned about his own treatment. Choosing not to wear braces as a child left Amos with a crooked smile. Being broke but having unlimited access to all the high-end equipment from his lab at college, Amos decided to take things into his own hands.

Some cheap alginate powder that gave him a mold of his teeth along with a 3D laser scan that could translate imagery into existence which finally was fed into a 3D printer, he was able to print a model of his braces. At the cost of $60, he now has a fully functional set of bracers that are doing wonders for him. This is clearly an indication that 3D printing can be widely used in dentistry for treating the untreatable.

3D printers capable of outputting in colour and multiple materials already exist and will continue to improve to a point where functional products will be able to be output. With effects on energy use, waste reduction, customization, product availability, medicine, art, construction and sciences, 3D printing will change the manufacturing world as we know it.

Facebook All Scandals Of Past Year,Facebook Data Leaks,Startup Stories,Technology News 2018,Startup News India,Facebook Scandals Past Year,Cambridge Analytica,Facebook Data Breach,Facebook Internal Struggles,Facebook Data Leaks Breach,Facebook CEO Mark Zuckerberg,Largest Online Social Media Platform

Facebook, in recent days, has been embroiled in scandal after scandal. On Wednesday, it was revealed that the initial numbers exposed by the Facebook data leaks were far higher than the 50 million declared by the social media platform. In fact, the numbers are closer to 87 million, a good 30 million more than the declared figures! However, with Zuckerberg’s confessions in front of the Congress, the other scandals Facebook has been going through has been brought to light.

1. Cambridge Analytica 

Cambridge Analytica, the political analysis firm, acquired the data of millions of Facebook users via an app created by a Professor at Cambridge. The data breach was considered a massive violation of information and was also linked to the 2016 Trump Presidential Elections. According to recently revealed reports, the analytics firm had used the revealed information to get an idea of the voters way ahead of the elections. The revelations sparked a massive reaction from the Senators in Washington. This, in turn, led to the #DeleteFacebook moment, with Zuckerberg being summoned to testify against the issue. After a long and omminous silence, he came forward and clarified all the questions posed by the members. The issue is still going on, without a clear idea on the resolve.

2. Retaining deleted videos of the users

One of Facebook’s responses to the Cambridge Analytica incident was to allow users to download their data archive on the social network in order for users to fully understand what information Facebook stores. This move inadvertently trigged more outcry when users discovered that videos recorded on the platform they had thought they had deleted were still present in Facebook’s archives. Facebook in turn, apologized and called the retention an unintentional “bug.” But the error will likely do little to reassure the public in the wake of a much larger ongoing scandal.

3. Facebook’s internal struggles 

When the entire date leaks breach happened, Andrew Bosworth, the Vice President of Facebook, said the growth of Facebook as a company was far more important than the breach of certain individual’s privacy. This sparked off a huge controversy, with Bosworth going on record to clarify that he didn’t mean what he said.

4. The Russian Meddling 

One of the dominant scandals of the 2016 Trump Presidential elections was the fact that Facebook had allowed the Russians to spread their political propaganda on the social networking site. Facebook had admitted last year that fake Russian accounts had been purchased for more than $ 100,000 in ads. Facebook was additionally implicated in its role of distributing misinformation, also known as “fake news,” from phony news sites, more often than not targeted at Hillary Clinton during the campaign, but rampant on both sides nonetheless.

5. Photo and link scan over messenger 

One of the other privacy infringements which came to light during the data leaks breach was the fact that Facebook scans images and links sent via messenger. According to the company policy, the policy is followed to make sure the content used is as per Facebook standards. While the practice may seem standard, users took offence to the policy as they felt it was an impeachment to their privacy rights. Facebook has said it is looking into the issue and will get it fixed as soon as possible.

With Mark Zuckerberg coming forward and saying he will address everyone’s concerns with what is perhaps the largest online social media platform, the issue looks to be resolved soon.

Bitcoins Worth Rs20 Crores Stolen In India,Startup Stories,2018 Latest Business News,Startup News India,India Biggest Crypto Bitcoins,Bitcoins Business News,Largest Cryptocurrency Thefts in India,Biggest Bitcoin Theft,Bitcoins Stolen,Bitcoins Latest News,Indian Cryptocurrency Bitcoins Worth

In what is perhaps one of the largest cryptocurrency thefts in India, almost 438 bitcoins worth Rs. 20 crores were stolen from one of the leading cryptocurrency exchange firms. The wallets of this firm were hacked, leading to a scandal the size of which wasn’t seen before.

Coinsecure, the Delhi based cryptocurrency exchange, filed an FIR with the cyber cell accusing its Central Statistic Officer (CSO,) Amitabh Saxena, of syphoning off money from the firm’s wallet. The exchange firm urged the government to seize Saxena’s passport, fearing he may leave the country. A case has been registered against Saxena, under IPC sections and Section 66 of the IT Act.

The incident was discovered on Monday when the company was going through its wallets. A senior security officer discovered that all the bitcoins stored online had disappeared.  It was later found that the private keys where the password that is kept by the company and is stored offline, were leaked, leading to the hack.

Despite the company’s efforts to trace the hackers, the keys remained missing. All the data logs stored in the wallets were erased, with no trace of the stolen keys anywhere. Furthermore, as a result of the hacking, the company couldn’t find out to which account the bitcoins were transferred.

According to Mohit Karla, the founder and CEO of Coinsecure, the hacking seems to have been an inside job. The private keys, which contained the password, aren’t necessarily stored online. However, the Cyber Police discovered that the private keys were stored online for more than 12 hours, giving the hackers easy access to the cryptocurrencies.

The police have seized the company’s systems in order to make certain the extent of the breach. The officers are also going through the database to see how many wallets have been compromised during the hacking. The senior security officials of the company have also been called in for questioning.

Death and immortality have always been a fascinating field of interest for humans. Ever since we learned how to make fire and use it to our advantage, we have wanted to learn more about life, death and life after death. The idea to stay alive forever however, seemed like a far fetched idea. Until now!

The past couple of decades has seen technology develop at an alarmingly fast rate. Starting from the telephone to connecting people around the world through one small device, tech advancements have made many things that once seemed far fetched, a reality. Scientists, researchers and inventors alike have claimed that soon humans will be able to download their personality onto a supercomputer.

Dr. Michio Kaku, an American theoretical physicist, futurist and popularizer of science, is one of the believers of virtual immortality. Speaking about the idea of living through a computer program, in the documentary Curiosity Stream, he said, “Imagine being able to speak to your loved one after they died, but it is possible if their personality has been downloaded onto a computer as an avatar. You would be able to communicate with them as if they were still here. They would, in effect, become immortal.

Following the same school of thought, many startups around the world have been researching for means to preserve the personality of people. Advanced artificial intelligence, cryogenics, anti aging research and virtual reality are helping people move from blind faith and towards science and technology as a source of hope for immortality.

In a post about why you should upload yourself to a supercomputer, Canadian bioethicist, transhumanist and futurist, George Dvorsky said, “Many credible scientists, philosophers and futurists believe there’s nothing inherently intractable about the process. The human brain an apparent substrate independent Turing Machine adheres to the laws of physics in a material universe. Eventually, we’ll be able to create a model of it using nonbiological stuff and even convert, or transfer, existing analog brains to digital ones.”

USA based startup Human Resurrection through Artificial Intelligence or HUMAI also plans to make immortality a reality. According to HUMAI’s CEO Josh Bocanegra, when the time comes, the company would be able to freeze the brain, create a new, artificial body, repair any damage to your brain and transfer it into your new body. On their website, the company further adds, “We’re using artificial intelligence and nanotechnology to store data of conversational styles, behavioral patterns, thought processes and information about how your body functions from the inside out. This data will be coded into multiple sensor technologies, which will be built into an artificial body with the brain of a deceased human.”

A software developer from the US, Eugenia Kuyda, developed a chatbot which is almost identical in speech to her late friend, Roman Mazurenko, by feeding some 8,000 lines of text messages into a Google programme. The programme is designed to allow people to create chatbots which in turn creates an experience as if it were two humans chatting. While the programme is very similar to an episode of Charlie Brooker’s futuristic TV show Black Mirror, the bot would help people who are grieving, find peace and solace.

Although the predictions seem like they belong in a science fiction book or movie, there are people all over the world contributing to a form of technology that may one day allow humans to live forever.
