A trip to space would be a life-changing experience. But scientists didn’t realize how much it changes astronauts when it comes to the building blocks of life.
Scott Kelly was in space from March 2015 to March 2016, Newsweek reported.
His identical twin brother Mark kept his feet firmly planted on Earth.
The two men were identical, down to their cellular level, before the trip, but that can’t be said now.
Scott now differs from Mark when it comes to their DNA.
Getting into the science specifics.
Scientists looked at the spaceman’s metabolites, cytokines and proteins before and after his voyage. They said the mission caused Scott’s “space genes” to switch on, and they didn’t turn off after he returned to Earth. The experts believe they were turned on because of the stress of space travel, KTLA reported.
NASA said in the study that Scott’s cells showed changes in the length of telomeres, the ends of chromosomes that show biological aging. They were lengthened while he was in space, but they returned to almost normal days after he landed. There was also damage to his DNA that was caused by radiation and the restriction on his calories. His collagen, blood clotting and bone formation also changed and because of zero gravity and fluid shifts.
Kelly’s year-long trip in space was a precursor to planned three-year missions to Mars. Scientists needed to test how space missions that are longer than what is currently done impacts astronauts, KTLA reported.

Your kids are begging for the latest and greatest cellphones to hit the market.
They may not like a new one that’s being introduced, but you sure will like them to have it.
It can call and it can text. But it cannot use Facebook, Snapchat, Instagram or any other social media.
Basically, it’s an old-fashioned flip phone without the flip phone look.
It also uses E-Ink for the display and operates on a modified version of the Android operating system, the Telegraph reported.
“Unlike a flip phone, however, to children the Light Phone is seen as ‘cool’ amongst their peers,” Joe Hollier, co--founder of Light told “Good Morning America.” “We have been working with parents on the idea of a parental app to support their child’s Light Phone 2 as well.”
Light launched it’s first phone in 2016. It could only make calls and store nine numbers, the Telegraph reported. The company sold 10,000 devices, but they were too simple for many and were not practical for some, the Telegraph reported.
Light Phone 2 are expected to ship next year and will cost about $250, the Telegraph reported.
If you want to get in on the new technology, the company launched an IndieGoGo campaign to raise $250,000. So far it has exceeded that amount by 335 percent and has more than $836,000 pledged from supporters.
Researchers from Google and sibling company Verily Life Sciences have developed a new algorithm using artificial intelligence to predict the risk of heart attack, stroke and other major cardiovascular events.
How does it work? Through the eyes.
Scientists studied data from 284,335 patients and found the “deep-learning” AI algorithm could identify risk factors based on age, blood pressure, gender, smoking status and others just by scanning the individuals’ retinas.
“The rear interior wall of the eye (the fundus) is chock-full of blood vessels that reflect the body’s overall health,” the Verge reported. “By studying their appearance with camera and microscope, doctors can infer things like an individual’s blood pressure, age, and whether or not they smoke, which are all important predictors of cardiovascular health.”
Google’s AI was able to differentiate patients who suffered a major cardiac event in the following five years and those who didn’t with a 70 percent accuracy.
"While doctors can typically distinguish between the retinal images of patients with severe high blood pressure and normal patients, our algorithm could go further to predict the systolic blood pressure within 11 mmHg on average for patients overall, including those with and without high blood pressure," lead author Lily Peng wrote in a Google blog.
Medical algorithms are traditionally created to redesign experiments to test hypotheses made from observations. But this algorithm found new ways to analyze existing medical data.
“With enough data, it’s hoped that artificial intelligence can then create entirely new medical insight without human direction,” the Verge reported.
This technology would make it more efficient for doctors to analyze cardiac risk without a blood test, which typically predicts events with 72 percent accuracy. But more tests are necessary before the AI can be used in a clinical setting.
“We look forward to developing and testing our algorithm on larger and more comprehensive datasets. To make this useful for patients, we will be seeking to understand the effects of interventions such as lifestyle changes or medications on our risk predictions and we will be generating new hypotheses and theories to test,” Peng wrote.
The research was published Monday in the journal “Biomedical Engineering.”
Robots are already changing the world around us – and in some people’s minds, getting ready to take over the world – but at least one of them has good manners.
Boston Dynamics, the company behind Atlas (an upright bipedal robot that looks like it’s wearing a space suit), Spot (a 4-legged robot that sprints like a cheetah) and Handle (a wheeled robot that can spin, squat and jump), has introduced their newest creation – SpotMini, a robot the company has taught to open doors.
The newest video is only 45 seconds long, but it shows one discouraged SpotMini that gets stuck at a door. Thankfully, another SpotMini arrives – and this one is built with an arm that can grab the handle and pull the door open, allowing the first robot through before following behind.
Boston Dynamics designs robots with real-world applications that range from searching damaged buildings to chasing criminals.
Former Lyft employees say the company spied on riders, and now the ride-sharing service is investigating the claim.
According to a report from The Information, a current or former employee made an anonymous post online claiming to have seen employees look up rider data on friends, exes, porn stars, actors and Facebook CEO Mark Zuckerberg.
Tech Crunch reported that it spoke with a source who once worked with Lyft. The unnamed source said staff can see feedback, rider history and pickup and dropoff coordinates.
“Maintaining the trust of passengers and drivers is fundamental to Lyft,” the company said in a statement. “The specific allegations in this post would be a violation of Lyft’s policies and a cause for termination, and have not been raised with our Legal or Executive teams. We are conducting an investigation into the matter.
“Access to data is restricted to certain teams that need it to do their jobs. For those teams, each query is logged and attributed to a specific individual. We require employees to be trained in our data privacy practices and responsible use policy, which categorically prohibit accessing and using customer data for reasons other than those required by their specific role at the company. Employees are required to sign confidentiality and responsible use agreements that bar them from accessing, using, or disclosing customer data outside the confines of their job responsibilities.”
A timeline for Lyft’s investigation was not provided, according to CNN.

If you needed a reason not to bite your iPhone battery, here it is.
According to Taiwan News, a man entered an electronics store in China hoping to purchase a replacement battery for his iPhone.
In an attempt to test its authenticity, the customer reportedly bit into the battery and as he removed it from his mouth, the product ruptured, exploding in his face.
Luckily, no one was injured.
The episode came soon after outrage over Apple’s admittance to slowing down older iPhone models with aging batteries led to big discounts on replacement batteries around the globe, including in China.
“However,” Taiwan News reported, “Chinese electronics stores are notoriously replete with fake goods, thus the man was in his own – but obviously wrong – way trying to test its authenticity.”
Lesson of the story: Don’t bite into your iPhone battery.
Unveiling its cryptocurrency grades, Weiss Ratings said Wednesday that Ethereum rates a B, or “good,” while Bitcoin gets just a C+, for fair. No virtual money earned an A, or “excellent.”
Meanwhile, Weiss Ratings founder Martin Weiss said his staff was up all night fending off denial of service attacks. The Palm Beach Gardens, Florida, company responded to the cyberattacks by expanding its server capacity.
“Commentary on social media expressed considerable fear we were about to release negative ratings on their preferred currencies,” Weiss said. “So this may be an attempt to thwart our release today.”
In addition to swarming its servers, Weiss said, cryptocurrency partisans also spread phony ratings of their preferred alt-coins.
The new Weiss Cryptocurrency Ratings evaluate alt-coins on price risk, reward potential, blockchain technology, adoption, security and other factors. Some of the grades:
• Bitcoin (C+) gets high marks for security and widespread adoption but low grades for network bottlenecks and steep transaction costs.
• Ethereum (B), the second most popular cryptocurrency, “benefits from more readily upgradable technology and better speed, despite some bottlenecks,” Weiss said.
• Novacoin (D) and SaluS (D) get subpar grades driven by a lack of technological innovation and meager adoption.
• Steem gets a B-, thanks to “a relatively good balance of moderate strength in nearly all the key factors considered along with a social network feature,” Weiss says.
While Weiss doled out no As, he doesn’t consider himself a hater of virtual money.
“Despite extreme price volatility, cryptocurrencies have a bright future and the potential to deliver unusually large profits to investors,” Weiss said. “However, the market is hectic and confusing for investors. They need the clarity that only robust, impartial ratings can provide.”
Officials with technology giant Amazon on Thursday announced that the company has narrowed down its list of possible sites for its second headquarters to 20 metropolitan areas.
The company said it got nearly 240 proposals from across the U.S. Canada and Mexico.
“All the proposals showed tremendous enthusiasm and creativity,” Holly Sullivan, with Amazon Public Policy. “Through this process we learned about many new communities across North America that we will consider as locations for future infrastructure investment and job creation.”
The following metropolitan areas are still in the running for Amazon’s second headquarters:
Amazon employees will spend the next several months diving into the remaining proposals. Company officials said Amazon’s decision will come this year.
Amazon is headquartered in Seattle, but the company announced in September 2017 that it was seeking proposals to build its second headquarters somewhere in North America.
Amazon officials said the company plans to invest $5 billion in its second headquarters, which will bring as many as 50,000 high-paying jobs to whichever metropolitan area it gets built in.
“In addition to Amazon’s direct hiring and investment, construction and ongoing operation of Amazon HQ2 is expected to create tens of thousands of additional jobs and tens of billions of dollars in additional investment in the surrounding community,” Amazon employees said in a news release.
If you own bitcoin or other cryptocurrencies, it might be a bad day for you.
The price of bitcoin plunged by 15 percent Tuesday morning, dropping below $12,000 for the first time since Dec. 4. Other cryptocurrencies have also seen price declines, with Ethereum falling by 20 percent and Ripple falling by 33 percent. The plunging prices are a stark difference to the success bitcoin saw last month — hitting a record of nearly $20,000 on Dec. 16.
As the digital currency bitcoin surges in popularity, curious investors and entrepreneurs alike are watching closely to see what happens with the fluctuating prices. Don’t understand the basics of bitcoin? Here’s what you need to know:
What is bitcoin?
Bitcoin is a cryptocurrency, or a digital token, that can be sent electronically and directly from peer to peer. There is no physical backing and it is a decentralized currency — meaning it is not controlled by any government or banking entity. Bitcoin is the first cryptocurrency ever created, and remains the most popular one to date.
“I tell people it’s a digital currency and it’s a program,” said Jad Mubaslat, Wright State University graduate student and founder of BitQuick.co, a bitcoin trading platform. “For the first time in history, it allows anyone anywhere in the world to send any amount of money instantly. Most importantly, it’s without a third party … like a bank or a government. Now, you can truly send your money without somebody telling you what you can or cannot do.”
The record of all bitcoin exchanges and transactions are on what is called the blockchain, which is a network of decentralized computers.
How was bitcoin created?
Bitcoin was created by a programmer going by the name Satoshi Nakamoto in 2008. He communicated only through email and social messaging, and no one truly knows Nakamoto’s identity. He released the software globally in 2009, and now anyone can use and download it.
How do you buy bitcoin and other cryptocurrencies?
In the U.S., several websites have popped up where you can buy and sell bitcoin online. One of the most popular websites is Coinbase and others include Mubaslat’s BitQuick.co, Coindesk.com and bitcoin.com. Investors can also meet with other bitcoin users in person and trade bitcoin via their virtual wallets on their phones. After meeting another bitcoin user through websites like Craigslist or LocalBitcoin.com, a user simply scans a QR code with another person’s wallet to transfer bitcoin.
Some people prefer to buy bitcoin in person or through a bitcoin ATM because the bitcoin transfer over faster than when they buy it online — it can take up to seven days, and sometimes longer, for bitcoin to show up in a virtual wallet after purchasing it online.
Why do some criminals use cryptocurrency for illegal transactions?
Some criminals use bitcoin because users can open a wallet to send and receive bitcoin without giving a name or identity. There is no bank or central authority, like a government, to control this information. Bitcoin also became a popular method for making ransom payments when a computer system is taken over by ransomware.
However, bitcoin is not completely anonymous and transactions can be traced by police through bitcoin trading websites. Other untraceable cryptocurrencies, like Monero, are becoming popular for dark web uses including drug trafficking and human trafficking.
How is the worth of bitcoin decided?
The price — and ultimate worth — of bitcoin fluctuates, and experts are calling the cryptocurrency extremely volatile. The price is determined by open-market bidding on Bitcoin exchanges. The worth of bitcoin could be compared to the way that gold prices fluctuate — in the sense that gold has value because people believe it does.
What exactly is bitcoin mining?
Mining is the process that creates new bitcoins in the blockchain, or network of computers. The bitcoin miners race to process new transactions, and the fastest computers get a chunk of new bitcoin. A miner wins the race about every 10 minutes, which will happen until there are 21 million bitcoins in the world. No new bitcoins will be created after the blockchain has 21 million, which is expected to happen in 2140.
Anyone can set their computer up to mine bitcoin, but programmers with specialized hardware are usually the only ones to win bitcoin now.
Are there any other cryptocurrencies as popular as bitcoin?
Other cryptocurrencies also exist, but bitcoin is the most popular one right now. Other popular cryptocurrency includes Ethereum, Bitcoin Cash, Ripple, Litecoin and Monero. Digital cryptocurrencies are being created for all types of uses like the legal marijuana industry and adult entertainment and sex worker industries.
What are the legal uses of bitcoin?
Most transactions on the bitcoin network aren’t illegal — it’s typically people buying and selling bitcoin to each other. People in countries with high inflation or unstable governments are putting their money into bitcoin to avoid losing their savings. It’s also used to transfer large sums of money internationally. It is quicker to transfer bitcoin than it is to go through a bank transfer, which can take weeks.
Some businesses also accept bitcoin, including Overstock.com, Wikipedia, backpage.com and Square. For a short time, a franchise of Firehouse Subs in Cincinnati accepted bitcoin. The restaurant, in Clifton, shut down a few years ago. “Firehouse Subs didn’t do very many transactions in bitcoin, but it has generated buzz around the shop,” the Cincinnati Business Courier wrote.
If you’re tired of your iPhone battery not performing and you’re running an iPhone6 or later, you’re in luck.
Apple is replacing the batteries now, instead of waiting for the original end of the month start date.
But, the tech giant warns that supplies may be limited, CNN reported.
Recently it was discovered that Apple was slowing down, or throttling, older phones to make sure they didn’t shut down unexpectedly.
The code was pushed out in an iOS update last year, CNN reported.
Apple says that the code was for older lithium-ion batteries, but a new battery should make phones return to normal speed.
Customers believed that the throttling was started so people would upgrade to newer models.
The company, in a letter to customers posted to Apple.com, said that the slowdown wasn’t an attempt to make people buy new technology.
The batteries, which usually cost $79, originally were able to be replaced with the $50 discount at the end of January, but the company started the program early. It is expected to run until the end of the year, USA Today reported.
To get the battery replaced, visit an Apple Store, an Apple certified retailer or send the phone to Apple support, CNN reported.
