ElliottWaveTrader launching cryptocurrency service – CryptoNinjas – CryptoNinjas

Posted: July 3, 2017 at 7:52 am

It was announced recently from ElliottWaveTrader.net (EWT), a live Trading Room of market analysis, based on Elliott Wave principle, that due to high demand and many requests, they will start a cryptocurrency service based onElliott Wave analysis. To lead this new service, the firm has brought on Ryan Wilday.

Ryan has over 17 years experience trading equities, futures, and options. He was introduced to cryptocurrency in 2013 by a programmer friend and began mining and trading shortly thereafter.

The EWT team stated:

Though he read Prechters Elliott Wave Principle in the early 2000s, he didnt make practical use of the theory until joining EWT in 2015. Today he melds his deep knowledge of the cryptocurrency market with Elliott Wave theory and Fibonacci Pinball.

Ryans service will be opening in August of 2017, more information will be forthcoming on the launch.

ElliottWaveTrader benefits traders looking to anticipate the direction of U.S. & world equity indices, stocks, bonds, precious metals, energy & forex over a time horizon of several days to several months.

The site also features insights and interaction by its community of traders, many of them professionals, as members are encouraged to post questions and contribute their own analysis in the interactive room.

How the cryptocurrency market and certain assets within react to Elliot Wave analysis will be quite interesting to observe.

The Rise of Decentralized P2P Crypto-Currency Lending – NEWSBTC – newsBTC

Posted: at 7:52 am

Cryptocurrency lending is about to boom. Today, crypto-currency lending is a field that does not have a plausible service provider due to the pseudo-anonymous nature of crypto-currency. The underlying issue with crypto-lending is the repayments of loans. How do people that do not know each other trust each other?

Trustless lending. ETHLend is a decentralized crypto-currency lending application that runs on Ethereum network, which is accessible through MetaMask, an Ethereum network browser. ETHLend solves the issue of trust by allowing the borrower to secure a crypto-loan with ERC-20 compatible Ethereum-based tokens. ERC-20 tokens can represent any value (such as shares or commodities). If the borrower does not repay the loan, the pledged tokens are transferred to the lender, who can sell the tokens on exchange to regain any losses.

Today, tokens are used mainly for fundraising. However, there are tokens that represent value from the real world, such as the DigixDAO token. Each DigixDAO token represents 1 gram of gold by tokenization. Even if tokens are associated with volatility, factually tokens are sufficient for securing a loan. First, the market price of tokens are usually available at different exchanges. Secondly, the volatility can be assessed and taken into account.

Alternatively, ETHLend provides another option, where the borrower can use Ethereum Name Service domain (ENS domain) as a collateral for the loan. ENS domains by design locks Ether (ETH) when the domain name is auctioned. Since ENS domains are transferrable, they can be easily used as a collateral against Ether loans. For example, borrower has ENS domain that has locked 10 ETH. The borrower cannot use this locked Ether. However, the borrower can pledge this domain for a loan to receive 10 ETH. If the borrower does not repay the loan back, the ENS domain is transferred to the lender (who can auction it to regain any losses).

Decentralized lending removes barriers and lowers costs on interest. ETHLend aims to provide a global liquidity pool between peers. The decentralized model and the use of crypto-currency is the proper solution to achieve ETHLends goal. Global liquidity pool means that a borrower in the US would not be limited solely to local lenders and US banks. Instead, the borrower can access funding from all parts of the world, such as Asia and Europe. Moreover, ETHLend wants to remind that there is 2 billion people without the access to any banking system. Lending crypto-currency would mean additionally access to finance for the unbanked.

Big plans for ETHLend. According to the white paper, there are lot of technical upgrades coming up for ETHLend, such as unsecured lending where borrower does not need a collateral to get a loan. Moreover, lending reputation system is about to be launched, where the borrower is rewarded with ETHLends native Credit Token (CRE), which can be used as a collateral by sparing other ERC-20 tokens.

We interviewed the Founder of ETHLend, a law student from Finland and a blockchain developer, to get more insights over the project.

Who are the people behind ETHLend?

We are a dedicated team of 14 people. We are working hard to provide blockchain technology for the mainstream. We want to democratize lending. This means that we want to remove interest rate differences between different countries and provide liquidity to lower interest rates in general. This would mean that borrowers would pay less in interest costs when there is more competition in a global scale. Moreover, we want to serve people that the banks are not serving due to the lack of banking infrastructure.

Is lending secure on ETHLend?

ETHLend is a decentralized application that runs on Ethereum blockchain network. We use Smart Contracts for the loan transactions. This means that each loan that is deployed on Ethereum blockchain cannot be changed, stopped or compromised by a third party (not even ETHLend).

Moreover, since all transactions are decentralized, we do not hold any assets or data. All assets such as ETH, ERC-20 tokens or ENS domains are held by the Smart Contracts. Any lender or borrower can explore loans on blockexplorer, therefore we are transparent by design.

What crypto-currencies can I borrow and lend?

Now, Ether (ETH) lending is available. We chose to use ETH since that is the native token of the Ethereum network that we have built our application on. We are planning to add other cryptocurrencies such as Bitcoin, Litecoin and other altcoins. To get ETHLend to the mainstream, we think that Bitcoin is essential.

Why did you build on top of Ethereum network?

We decided to use Ethereum for three reasons. First, Ethereum has well established Smart Contracts, which allows to perform complex transactions such as lending and handling the collateral. Secondly, by using ETH, we do not have to communicate with two blockchains, which would not be ideal way to start a simple DAPP development. Lastly, even though ETH has a different purpose than Bitcoin, ETH is widely used as cryptocurrency.

How ETHLend differs from other blockchain projects?

We started by developing the application. We first created the decentralized application, instead of writing a white paper and opening a flashy website. I personally wanted to understand how decentralized lending would work in practice. As coming from a legal background and not from technical, I wanted to try it first and then write an analysis on my practical findings, the white paper.

Moreover, we have an amazing team working on ETHLend. I have never seen such extensive collaboration that we have at ETHLend. Practically we are all living in different parts of the world, but initially we have the same goal: to provide fair lending for all by using blockchain technology. We are also happy to have more people involved through our Slack.

What is your focus on the development?

Since we have an Ethereum-based application that runs stable, we are now focusing on adding more functionalities and user experience. Our goal here is to make decentralized lending as easy and accessible as possible. We want to keep the learning curve as low as possible. As a part of the user experience, we are adding more languages and ways to easily calculate the value of the collateral to avoid unnecessary loan requests.

Is there going to be an ICO?

We are going to have a token sale on early September. Our aim is to fund the further development of ETHLend and provide the largest lending market that works on a global scale. We want our future token holders to be part of it.

How the tokens are distributed?

We are distributing 1 billion Credit Tokens (CRE) for sale. There will be no follow up sales and all unsold CRE is burned. Additionally, 300 million CRE is allocated to the development fund as an incentive for our founders and developers to remain with the project. The development fund tokens will have a 24-month vesting model, which means that during this period, tokens are gradually released from lockup on each 6-months-period.

Getting ready for token sale. According to Stani, the ETHLend team is preparing for the upcoming token sale. The aim is to provide decentralized, secure, fair and democratic token sale. ETHLend is currently developing the Smart Contract for the token sale. However, the precise date of the token sale is not disclosed. ETHLend will inform the date of the token sale within couple of weeks.

Ethereum Price Drops Below $300 Amid Technical Issues and Cryptocurrency ICO Hype – The Merkle

Posted: at 7:52 am

Things are not looking all that great for Ethereum right now. The popular cryptocurrency suffereda major crash not too long ago and it remains the market is still recovering. The past two days have heralded another downturn for Ether, making it highly doubtful Ethereum will pass Bitcoin in market cap anytime soon. It seems safe to say more volatility is on the horizon for Ethereum holders.

Looking over the Ethereum price charts leaves traders and investors disappointed, as their hopes for challenging Bitcoins crown subside. More specifically, the ETH price has taken another beating, as it declined by 7.65% over the past 24 hours. This puts the value of one Ether well below the US$300 mark and it is possible this value will keep heading toward US$270 or lower over the coming days. This momentum is not entirely surprising given Ethereums bullish trend throughout the first half of 2017.

It is not hard to forget once ETH was worth under US$11 back in early January of this year. Things have certainly picked up over the past few months, culminating in an Ether price peak of nearly US$400, according to Coinmarketcap. Such a spectacular price increase can only be met with future price volatility, which is what we are seeing on a daily basis right now. Even so, the Ether value increase has been nothing short of impressivethis year.

Ethereum enthusiasts have referred to a phenomenon known as the flippening all year. This trend would occur once Ethereums market cap surpasses that of Bitcoin. Although both currencies were only separated by just US$8bn, the gap has widened once again. More specifically, Bitcoins market cap is close to US$41bn right now, whereas Ethereums is only US$26.32bn. The flippening will not be happening anytime soon at this rate.

The bigger question is why Ethereum is facing such a setback right now. Shifting market conditions are likely the culprit. Moreover, the Ethereum blockchain and its technology are weighed down by the influx of cryptocurrency ICOs. Transactions are confirmed far slower when a big ICO happens, and smart contracts used by these projects often contain issues which need to be fixed later on. The technology is still premature, yet investors also see this can become a much bigger problem if things arent resolved quickly.

Speaking of cryptocurrency ICOs, they have quickly become the main use case of the Ether currency. That is not necessarily a positive development either. With so many projects raising funds in Ether, the chances of a market dump will increase as well. When teams need funding, they will convert ETH to fiat currency, creating negative pressure across the exchanges. When more projects sell off their raised funds, the price per ETH will undoubtedly continue to go down quite quickly. It is unclear if that is part of the ongoing price drop right now, but it is something to keep in mind.

It is unclear what the future will hold for Ethereum right now. The Ethereum price is very volatile, which is only to be expected at this point. However, Ethereum is not a store-of-value by any means. With so many dumb money flowing into Ethereum to participate in cryptocurrency ICOs, it is virtually impossible to determine the real value of the existing coin supply. Technical issues are becoming a major problem as well. If this trend keeps up, the flippening may never happen at all. These are interesting times for Ethereum to prove its value, but so far, the projectleaves quite a bit to be desired.

A golden crypto currency you can invest in for as little as $45 – Sun … – The National

Posted: at 7:52 am

Ibrahim Mohammed is the founder and chief executive and OneGram, a new digital currency, at the company's offices in Emirates Financial Towers in the DIFC area of Dubai. OneGram is partnering with GoldGuard, a Dubai-based online gold trading platform to build one of worlds largest gold vaults inside the Dubai Airport Free Zone. Christopher Pike / The National

As the founder and chief executive of OneGram the Dubai-based technology company behind the first digital currency completely backed by gold - Ibrahim Mohammed is confident his cryptocurrency will be a success, even as competition in the digital currency sphere hots up.

He says with 100s of new coins releasing every day, it is OneGrams unique selling point - the fact that the currency is fully Sharia-compliant - that will set it apart.

The company has already launched an Initial Coin Offering (ICO) offering, which aims to raise more than US$500 million in capital; the tokens were launched on May 21 and will be available to buy until September 22.

OneGram has partnered with GoldGuard, a Dubai-based online gold trading platform, for the offering, with each token backed by one gram of gold, held in a vault at Dubai Airport Free Zone. Only 12.5 million tokens are available to buy in total.

The OneGram currency was created using blockchain technology, a digital method of recording data that underpins the digital currency bitcoin.

While one bitcoin today is currently worth about US$2,500 (or $2,438 at the time of writing), to buy a OneGramCoin would set you back $45 at current market prices.

Almost six weeks after the OneGram coin first went on sale, Mr Mohammed, a British Dubai resident with 10 years of experience running companies whose specialisms have included debt collection and business formation, explains how the new digital currency works and how investors can get on board:

Why did you set up OneGram?

Because of the ruling that happened in November 2016 from the Accounting and Auditing Organisation for Islamic Financial Institutions (AAOIFI) with regards to the gold standard. It was the first time gold was deemed to be a sharia-compliant product and it got us thinking. It evolved into digitisation ofgold but then having bigger returns rather than just waiting for the market to go up - so we combined it with a digital currency.

How does OneGram work?

Its like bitcoin; its a digital currency but the major difference to any other crypto is that its backed with physical gold. Putting it very simply, if you have one bitcoin today thats worth about US$2,500 and if it crashes and went to zero youd lose all your money. With OneGram, if you buy today you pay about $45; $41 of that is in physical gold but $4 is in the coin, so if OneGram crashed you would potentially lose $4 and still have $41. Essentially its a digital token - a digital form of payment.

So how can you use this form of payment?

Globally, these kinds of tokens are mainly used in the crypto community by people that believe in [the concept] and are willing to hold it. What we are trying to develop over the next 12 months or so is a payment solution that retailers can adopt to accept payment. At this stage (until the OneGram coin is listed in September), its like holding stocks or shares. The demand is there and the prices are increasing; if you follow the crypto market at all it was worth $20 billion in 2016 and this year its worth $100bn as we speak. Most of that jump has happened in the last five months.

What is driving that?

People see the potential in it. Most governments now are talking about how to regulate the market and control it and bring it into mainstream. The growth is phenomenal. I dont think investors are risk takers because the model of crypto currencies has been proven. Japan has legalised bitcoin; its inevitable that others will follow suit.

How does OneGram work?

Register at GoldGuard.com and where you go to buy you will see the live spot price of gold and it will be a live spot buy. Underneath it you will see the coin value of $4 - thats 10 per cent of the actual transaction and thats the coin fee. You will see a total price of $45; its approximate on the site as its linked to the Allocated BullionExchange's live gold fee. You can transfer funds or buy through bitcoin but we wont accept bitcoin directly as we dont know the source of funds, so we use a company called BitPay in the United States. They do all the verifications, as they are regulated by the US government and they will accept the bitcoin and wire us US dollars.

Is the $4 a fee then?

Its a kind of administration fee because typically in crypto currencies you are paying the whole amount - so if we didnt have gold youd be paying $45 and wed have all money. But we only take 10 per cent which covers operations, staffing, support, marketing, development, blockchain etc. With typical cryptos, if they are selling at $45 they may pay 30 to 40 per cent commission on transactions and theyll sell out in a day or two. Weve adopted a real business model as opposed to a "lets loot type of crypto." So there is a 10 per cent mark up on the price to give our investors the best possible chance of higher returns and that 10 per cent will cover our costs to operate.

What happens when you list?

Then you will have your own wallet and you will hold it on your own iPad, phone or desktop. The coin will be listed on a few digital currency platforms, so any buying or selling happens through those platforms and it goes into the secondary market. In terms of where the price can be at launch and where it can be in 24 months is completely beyond our control. Some analysts have said OneGram is the closest coin that has ever come to knocking bitcoin off its pedestal.

Who are your investors?

As well as crypto tech investors, were getting people that have never invested in cryptoor digital currencies before but because of the gold aspect and the sharia regulatory aspect they are very comfortable. We get customers buying for $100 and in the same day someone will buy $200,000. There is massive interest from Africa and Pakistan, countries we never expected. We now have 4,000 to 5,000 registered users and the majority are non-Muslims;another surprise.

What happens if you dont sell all the 12.5 million coins?

Anything that is left will be burnt wiped away. If we dont sell all of them then it's likely the price will go up as there will be less in circulation. We left the first month open for anyone to buy. Now we have our affiliates, partners that will also sell the coin. The first affiliate is $100m, there are a couple more after that. We are not in any doubt that the coin will sell out.

How many have you sold so far?

Twenty-two per cent of the ICO has already been assigned thats about 2 million coins.

Once the coin is listed what happens to OneGram?

Our ongoing role is to maintain the blockchain and security of it so that the coins can trade. And we make 1 per cent of every trade, the typical fee within blockchain.

Who are you licensed by?

Cyptos are not licensed but the part that needs licensing is GoldGuard, which is a gold trading platform. That is licensed by Dubai Airport Free Zone so we are licensed to trade gold.

Can investors see the gold?

Our vaulting partner may have security issues with that but once we have our own vaulting systems we will be open to anyone that wants to inspect. For verification that the gold exists, our auditors PwC have to physically go and count the gold along with our sharia advisers so I think the investors can rest assured that the gold exists. We buy through ABX and within three days they physically store it for us.

How could it all go wrong?

Its very difficult to go wrong because the exposure is very limited its 90 per cent in gold, 10 per cent in the coin. The demand is there and the market is there so unless someone turns the internet off

Whats next?

Were in discussions about ATM machines. You could have an ATM machine in Dubai, Hong Kong or London where OneGram can be bought and sold across the globe.

Reused Dragon departs Space Station after month-long science bonanza – NASASpaceflight.com

Posted: at 7:51 am

July 3, 2017 by Chris Gebhardt

After 30 days in space and 28 days berthed to the International Space Station, SpaceXs first ever reused Dragon capsule hasunberthed from the Station ahead of a Monday afternoon reentry and splashdown in the Pacific Ocean for recovery. Over the course of its month-long stay, Dragon delivered several thousand pounds of scientific experiments and equipment to the Space Station some of which were so time sensitive that they had to be performed in the past 28 days so they could return with Dragon today.

Dragon departure and splashdown:

Originally scheduled to depart the ISS and splashdown in the Pacific Ocean off the coast of Baja California on Sunday, 2 July, Dragons homecoming was delayed one day due to unfavorable weather conditions in the Eastern Pacific.

Dragon has performed flawlessly during her mission while the three person ISS crew has spent the last 28 days unloading the capsule, performing the timesensitive experiments that are due to return on it, and removing external payloads for the Station from Dragons trunk toeither attachthem on ISS or to perform test objectives on them.

The mission holds a historic place for SpaceX being the first re-flight of a Dragon capsule that had already flown to space once prior.

Previously, the Dragon capsule used for CRS-11 had flown the CRS-4 mission in September-October 2014.

The reuse of this Dragon capsule marksthe first time a private spaceflight company has reused a spacecraft and also marked the first time that a reused spacecraft arrived at the International Space Station since the conclusion of the Space Shuttle Program in 2011.

With Dragons first reflight now set to conclude, the three person reduced crew aboard the International Space Station began robotic preparations for the vehicles released by grappling Dragon with the Space Station Remote Manipulator System (Station arm or SSRMS) over the weekend ahead of final hatch closer on Sunday.

Firmly held in the snares of the Latching End Effector (LEE) on the end of the SSRMS, bolts securely fastening Dragon to the nadir (Earth-facing) Common Berthing Mechanism of Node-2 Harmony were driven to the retract position, freeing Dragon from its berthing port on the Station.

The Station crew then maneuvered Dragon on the end of the SSRMS away from the main structure of the ISS to its release point 10 meters from the orbital lab.

With a release time of 02:41 EDT on Monday, 3 July, astronauts Peggy Whitson and Jack Fischer working in the Cupola lab of the ISS commanded the release of the LEE snares holding Dragon.

The exact time of release was subject to change from the announced plan due to lighting conditions, communications coverage, and day-of timeline activities.

Once the LEE snares released, Whitson and Fischer backed the SSRMS away from Dragon as the craft held its position at the 10m mark.

Once the Stations arm was cleared to a safe distance, Dragon was conducted through a series of three small thruster firing departure burns that moved the capsule down the R-Bar (Radial Vector) and away from the International Space Station toward Earth (when viewed in relation to ISS orientation and Dragon movements with respect to Earth).

During the initial stage of departure, Dragon was under the control of its own computer programming, with Whitson and Fischer aboard the International Space Station and controllers at Mission Control Houston in Texas for NASA having primary control over the spacecraft.

As Dragon pushed down the R-Bar, the largest of the three thruster departure burns imparted enough Delta Velocity (Delta-V) change to Dragon to push it outside of the approach ellipsoid.

The approach ellipsoid is a 4 km by 2 km oval-shaped region around the International Space Station that extends 2 km in front of and 2 kilometers behind the ISS along the velocity vector (V-Bar) and 1 km above and 1 km below the Station along the R-Bar.

Once Dragon cleared the approach ellipsoid 1 km below the ISS, primary control of the vehicle shifted from NASA to SpaceX controllers in Hawthorne, California.

Dragon will perform roughly five hours of free flight activities as controllers at Mission Control SpaceX prepare the vehicle for the end of its mission.

Roughly five hours after departing the Space Station, the Guidance Navigation and Control (GNC) bay door on Dragon will be closed, creatinga perfect thermal protection seal around the entirety of Dragon for entry.

At the appropriate time, Dragons Draco thrusters will begin a 10-minute firing sequence known as the deorbit burn to slow thecapsule and place it on to the proper heading for entry into Earths atmosphere.

Following the deorbit burn, the umbilicals between Dragon and her external payload trunk will be severed ahead of the trunks separation from Dragon itself.

Dragon will then reorient, with its heat shield out in front in preparation for Entry Interface (EI) the moment Dragon reaches the first traces of Earths upper atmosphere.

Once EI occurs, Dragons Thermal Protection System (TPS) will protect it from the searing hot temperatures of reentry formed as the air molecules around Dragon are instantly heated and turned to plasma under the friction created by Dragons high velocity.

Dragons primary heat shield, called PICA-X, is based on a proprietary variant of NASAs Phenolic Impregnated Carbon Ablator (PICA) material and is designed to protect Dragon during atmospheric re-entry.

PICA-X is robust enough to protect Dragon not only during ISS return missions but also during high velocity returns from Lunar and Martian destinations.

Unlike the Dragon capsule, the Dragon trunk will destructively burn up in Earths atmosphere.

Once safely through the plasma stage of reentry, Dragons drogue parachutes will deploy, followed by the main chutes designed to ease the vehicle to a splashdown in the Pacific Ocean for recovery.

Recovery will be attained by three main recovery vessels which will be positioned near Dragons return location.

Fast recovery vessels will be deployed to begin collecting Dragons parachutes as recovery of the capsule itself is conducted by the primary recovery assets.

Once safely aboard the recovery vessel, Dragon will be transported to the Port of Los Angeles and then shipped to Texas for cargo removal.

Currently, Dragon is the only resupply vessel capable of returning experiments and equipment from the International Space Station as the three other in-service resupply vehicles (Progress, Cygnus, and the H-II Transfer Vehicle) all perform destructive reentries into Earths atmosphere.

Under the second Commercial Resupply Services (CRS-2) contract award, Sierra Nevadas Dream Chaser spaceplane will join Dragon as only the second uncrewed vehicle capable of returning equipment and experiments from the Station.

With the conclusion of CRS-11, NASAs next commercial resupply mission to the International Space Station will be SpaceXs CRS-12 flight, which is currently targeting liftoff from SLC-39A at the Kennedy Space Center on 10 August 2017 at 14:07 EDT.

The science of CRS-11:

In addition to the 524 kg (1,155 lb) of crew supplies, vehicle hardware, spacewalk equipment, and computer resources aboard Dragon, the craft delivered a crucial 1,069 kg (2,356.7 lb) of internal science experiments to the Station.

Among these experiments were some that had to be performed/started quickly when Dragon arrived at the Station, as those experiments had to return aboard Dragon for landing Monday.

Specifically, two of the experiments are related to the biological sciences, one using fruit flies and one using mice.

Fruit Fly Lab:

Fruit Fly Lab-02 (FFL-02) follows three previous fruit fly experiments: Fungal Pathogenesis, Tumorigenesis, and Effects of Host Immunity in Space, which flew aboard Shuttle Discovery on the STS-121 second Return To Flight mission in 2006; NanoRacks-HEART FLIES, which was launched on SpaceX CRS-3 in 2014; and Fruit Fly Lab-01 (FFL-01), which launched to the Station on CRS-5 in 2015.

Specifically for FFL-02, the experiment studies the underlying mechanisms responsible for adverse effects of prolonged exposure to microgravity on the heart.

To this end, theexperiment usesfruit flies (scientifically known as Drosophila melanogaster), as their well-known genetic make-up and very rapid aging make them good models for studying heart function.

According to NASA, a fruit flys heart develops and functions in a fashion remarkably similar to that of the human heart, and is an excellent model to study the molecular-genetic basis of cardiac development as the underlying molecular pathways and cellular functions are fundamentally conserved even to humans.

Moreover, fruit fly hearts have been used to determine fundamental causes of cardiac dysfunction, such as arrhythmias (a group of conditions in which the heartbeat is irregular, too fast, or too slow) and cardiomyopathies (diseases of the heart muscles), which can lead to heart failure and death in humans.

For FFL-02, the development of a microgravity heart model in the fruit fly, which is more genetically tractable and faster aging than vertebrate hearts, could represent a potentially significant advancement in the study of how spaceflight affects the cardiovascular system and may facilitate the development of countermeasures to prevent the adverse effects of microgravity in astronauts.

To this end, FFL-02 is comprised of six Vented Fly Boxes, each containing triplicate samples of five different fruit fly strains.

Once Dragon was launched into space, the ground-born flies developed to adulthood and reproduced.

The space-born flies then went through their life cycle the formative parts of which all took placed in microgravity before coming back on Dragon, at which point the space-born fruit fly hearts are compared to control ground-born fruit fly hearts.

Furthermore, the effects of microgravity are compared between samples composed of control fly strains and those composed of mutant flies that are genetically predisposed to two types of heart dysfunction: arrhythmia and cardiac dilation.

Direct application of this experiment for astronauts and future spaceflights include the development of a microgravity heart model which could significantly advance the study of spaceflight effects on the cardiovascular system and facilitate the development of measures to prevent the adverse effects of space travel on astronauts.

Ground-based applications for those of us not lucky enough to fly into space of FFL-02 include additions to the growing body of research on fruit flies as models for human heart health and improving efforts to use fly studies to develop new cardio therapies.

Systemic Therapy of NELL-1 for Osteoporosis Rodent Research 5:

Rodent Research 5 (RR-5) continues the study of bone density loss (osteoporosis) in space while also testing new applications and drugs that can rebuild bone and prevent further bone loss on orbit.

In short, RR-5 is an experiment to study the potential for a new drug, NELL-1, to slow and/or reverse bone loss during spaceflight.

According toNASAs coverage of the experiment, exposure to the spaceflight environment results in significant and rapid effects on the skeletal system, similar to what occurs in certain bone wasting diseases, as well as aging, on earth.

Studying accelerated bone loss in space provides insight into disease mechanisms, confirms potential new drug targets, and enables the preclinical evaluation of a candidate therapeutic targeted to such disease.

To carry out RR-5, 40 mice all females between the ages of 30-40 weeks, with 32 week old female mice being preferred were launched in the CRS-11 Dragon.

When Dragon berthed to the ISS on 5 June, the mice were transferred to Rodent Habitats aboard the Station.

There, they were divided into two groups: control (vehicle only injection and bone marker) and experimental (NELL1 injection and bone marker).

The first round of injections occurred at Launch +1 (L+1) week, with the 20 control mice receiving vehicle injections and the 20 experimental mice receiving NELL1.

After this first round, dual-energy X-ray Analysis (DXA) scans were performed on all of the mice.

From this point, a subsequent injection series occurred at L+3 weeks ( 1 day).

This weekend, just prior to hatch closure and Dragon departure, 10 control mice and 10 experimental mice were randomly chosen for Live Animal Return (LAR) and were transported back into Dragon for a return trip to Earth.

The remaining 20 mice (10 control and 10 experimental) will now remain aboardthe ISS, receiving a third and fourth round of injections at L+5 weeks and L+7 weeks.

At L+9 weeks, a third DXA scan will be performed (the second having occurred at L+5 weeks).

At this point, the final blood samples will be obtained from all the remaining mice, and those blood samples will then be wrapped in aluminum foil and stored at -80C or colder until return on CRS-12.

The RR-5 investigations are expected to increase understanding of ground-based diseases, disorders, and injuries affecting millions of people globally and aid in the development of new therapeutics and strategies to treat such conditions.

Specifically, this research holds the potential to lead to new treatments for bone loss associated with immobilization, stroke, cerebral palsy, muscular dystrophy, spinal cord injury, and jaw resorption after tooth loss.

Other major science experiments on CRS-11:

In addition to FFL-02 and RR-5, numerous other experiments launched aboard CRS-11, including: Microbial Tracking-2, Seedling Growth-3, Advanced Plant Experiments -02-2, and Advanced Colloids Experiment Temperature -6.

Microbial Tracking-2:

Microbial Tracking-2 (MT-2) is part of a Microbial Tracking series that seeks to better characterize the microbial communities present on the Station using cutting edge molecular analysis techniques.

Specifically, MT-2 will study how microbial communities on the ISS and short-living viruses in a closed habitat have an adverse influence on crew health.

MT-2 will help fully characterize microbes and viruses present on three different crew members and in the environment during consecutive expeditions.

To accomplish this, crew members will take saliva, mouth, and body samples at various points in the consecutive expeditions so their respective microbiomes can be fully assessed and compared to ground baseline samples from before and after their flights.

Additionally, crew members will obtain air and surface microbial samples from inside U.S. modules.

In this manner, MT-2 will not only describe the microbial and viral communities of the Station and the crew, but will also seek to distinguish whether these biological signatures are of any concern to crew health and engineering systems.

According to NASA, All microbial and viral data generated by the investigation will be hosted by GeneLab and will be available to the scientific community and NASA to compare population dynamics to baseline standards and enable more accurate assessments of crew health associated with a given mission and future mission planning.

Seedling Growth-2 and Advanced Plant Experiments -02-2:

Seedling Growth-3 (SG-3) is the third of the Seedling Growth Experiment series and uses the plant Arabidopsis thaliana (more commonly known as the thale cress or mouse-ear cress).

SG-3 specifically investigates the effects of gravity on the cellular signaling mechanisms of light sensing in plants (phototropism) and investigates cell growth and proliferation responses to light stimulation under microgravity conditions.

The results could provide improvements in agricultural biotechnology and can contribute to increased production, lessened environmental impact, and sustainability of agricultural production.

The European Space Agency (ESA) leads this experiment, which will be performed in the European Modular Cultivation System (EMCS) in the Columbus Module.

Separately, the Advanced Plant Experiments -02-2 (APEX 02-2) will collect quantitative measurements of radiation damage to yeast DNA exposed to space radiation.

APEX 02-2 will represent the first time a highly powered genome-wide analysis of mechanisms of radiation damage in space can be conducted made possible bystate of the art technologies.

Specifically, APEX 02-2 uses a genome-wide series of deletion clones of Bakers Yeast to determine the quantity of radiation damage during spaceflight in comparison to ground controls.

While performed on the ISS, APEX-02-2 holds both space-based and ground-based applications providing potential simple approaches to enhancing space-based and clinical radiation damage.

Advanced Colloids Experiment Temperature -6:

Advanced Colloids Experiment Temperature -6 (ACE T-6) is an investigation which aims to study the microscopic behavior of colloids in gels and creams.

Colloids are suspensions of microscopic particles in a liquid commonly found in products ranging from milk to fabric softener.

Consumer products often use colloidal gels to distribute specialized ingredients throughout a liquid or semi-liquid medium.

However, these gels must serve two opposite purposes: disperse the active ingredient and maintain an even distribution so the product does not spoil.

To this end, coarsening (to make or become rough) is an issue with colloids that can limit the shelf life of many products that use them.

As such, ACE T-6 seeks to provide new insight into colloid coarsening in an effort to better understand the mechanism behind it with an aim toward improving shelf life in consumer products.

Rocket failure may delay China’s space station and moon missions – New Scientist

Countdown to failure

By Timothy Revell

Chinas latest space launch has ended in failure. The Long March 5 rocketsuccessfully took off at 11.23am GMT on Sunday from the Wenchang Space Launch Centre in China, but after an hour came tumbling back down to Earth due to an abnormality.

Once in the air, mission control in Beijing tried to save the rocket by changing its flight plans, but those attempts were unsuccessful. The rocket, along with the experimental communications satellite it was carrying, crashed into the Pacific Ocean shortly afterwards.

The cause of the failure is still being investigated, but is likely to cause delays for future launch plans. This is the second Long March failure in two weeks, with a television satellite failing to hitch a ride into space on June 19. At the moment, its not clear if there is a connection between the two incidents.

China had planned to launch a rover into space by the end of this year, destined for the dark side of the moon, with the hope of bringing rock and soil samples back to Earth. But the mission relies on hitching a ride aboard a Long March 5 rocket, so may be delayed if the causes of the latest failures take a while to find and rectify.

Delays are possible. The rocket cannot fly until we find out the problem and solve it, and that will take time, said Wang Jianyu, the commander in chief of Chinas quantum satellite project who is also involved in the moon missions.

China also has plans to complete the construction of a space station, as well as landing humans and building a settlement on the moon. These missions will rely on Long March 5 rockets, so finding the points of failure is crucial to avoid lengthy delays.

NASA denies Infowars claim that the agency runs a child slave colony on Mars – Salon

Posted: at 7:50 am

NASA assured the public on Thursday that there was no child slave colony on the planet Mars, refuting a claim recently made by a guest on the popular The Alex Jones Show.

There are no humans on Mars, NASA spokesperson Guy Webster told The Daily Beastin a statement. There are active rovers on Mars. There was a rumor going around last week that there werent. There are.

But there are no humans, he added.

According toRobert David Steele, a former CIA officer who appeared on Alex Jones show this week, NASA had been shuttling children to the distant red planet for their blood, bone marrow and sexual exploitation.

We actually believe that there is a colony on Mars that is populated by children who were kidnapped and sent into space on a 20-year ride, Steele said this week on Infowars. So that once they get to Mars they have no alternative but to be slaves on the Mars colony.

Look, I know that 90 percent of the NASA missions are secret and Ive been told by high level NASA engineers that you have no idea, Jones said in response to the outlandish allegation. There is so much stuff going on.

Accustomed to dealing with conspiracy theories (and the bunk claims of certain websites owned by certain Oscar Award-winning actors), NASA provided a statement Thursday clearly explaining to the American people that no human, let alone no child, had ever touched foot on the planet Mars.

Infowars listeners will likely disregard the denial. A child slave colony on Mars might not even be the most absurd conspiracy theory floated on The Alex Jones Show.

A Brief History of Everyone Who Ever Lived: DNA, individuals, and species – Boing Boing

Posted: at 7:49 am

/ Cory Doctorow / 4:14 am Mon

British geneticist Adam Rutherford is one of the country's great science communicators, an alumnus of Nature whose work we've celebrated here for many years; with his second book, A Brief History of Everyone Who Ever Lived, Rutherford reveals how the century's astounding advances in genetic science reveal just how little we understand about our genes -- and how our ideas about race and heredity are antiquated superstitions that reflect our biases more than our DNA.

At its worst, scientific debunking can be a kind of grim and humourless exercise in which a distinguished scientist explains how you've got it all wrong and scientists really know very little about a subject that you thought they'd had nailed down, and you should really be couching all your statements about the truth of the world in so many caveats that no statements can be discerned. That's not Rutherford's style.

Rutherford is one of the most sprightly and delightful science communicators in the field, a writer who uses footnotes for comic relief with skill not seen since the heyday of Douglas Adams, whose delight in language is matched by a wonder for the things science does teach us, who uses that delight to shine a glorious light on marvels even as he pitilessly illuminates the often harmful bullshit that the public has been told to believe about what genetics says about them.

Rutherford's thesis is that the more we learn about our genome, the more we learn about ourselves as a species -- and the less we can know about ourselves as individuals. Population-wide genetic sequencing reveals truths about how closely related we all are (we're all cousins, and much closer ones than you probably suspect), how little our alleged "race" predicts about us, and how much of what we think of as "heredity" is more complicated and weirder than we've been led to believe.

Brief History challenges our understanding of what a species is, and what our species is, as the extraction of genomes from living specimens and ancient fossils reveals that humans, neanderthals and other cousins co-existed for unimaginably long timescales, and crossed and re-crossed their DNA. Contrast this profligacy and its outcomes with the closely guarded, inbred "noble blood" of Europe's royal houses, whose belief in their own genetic superiority led them to breeding experiments that produced insane, pain-wracked monarchs whose reigns were marred by seizures, delusions, and violent outbursts that only ended when the lines' terminal specimens could no longer breed.

The upshot of all this is that those 23-and-me-style genetic "analyses" that you can send away for are fairy tales, describing genetic propensities that are more likely to be statistical ghosts than real phenomena, and family histories that rely on categories ("Germanic," say) that have no objective basis in reality.

But while your individual sequence won't tell you much about who you are and where you came from, these corpuses -- especially the public interest ones gathered by research scientists and not private, woo-peddling companies -- are revealing an astonishingly detailed picture of humanity's pre-history.

Genetics and heredity have a checkered past: at its best, our study of DNA has given us breakthroughs in fighting disease, breeding better crops, and learning about our common destiny. At its worst, it has provided demagogues with scientific cover for racist rhetoric and violence. As a new era of data-driven genomics dawns, Rutherford is determined to rescue it from being turned to evil ends and elevate it to a pedestal from which it can teach us how much we all share with one another.

Police use DNA from discarded cigarette butt to link man to 2014 Chicago murder – Fox News

Posted: at 7:49 am

A discarded cigarette butt at the scene of a 2014 gang-related killing in Chicago led authorities to arrest and charge a man with murder Thursday.

Jeffery Freeman, 24, was charged with first-degree murder in the October 2014 alley shooting that left one man dead, the Chicago Tribune reported. A judge ordered Freeman held on $1 million bail.

Authorities said Freeman was instructed by his fellow gang members to go and check Torrence Pickens, who was smoking and drinking in an alley and moved to a car when members of Freemans gang approached Pickens for allegedly being on their territory.

Surveillance footage captured Freeman, who was smoking a cigarette, holding a loaded gun and walking toward Pickens. He tossed the cigarette butt as he approached Pickens and fired multiple gunshots.

Police found Pickens body sitting in the car. The person who was with Pickens gave a description of the shooter, according to the Chicago Tribune. The description matched Freemans.

Police also recovered the cigarette butt and video footage. A DNA sample from Freeman was then compared to the DNA from the discarded cigarette and it was matched, according to prosecutors.
