Sawfish are avoiding extinction by reproducing without sex This is the first time 'virgin births' have been seen in a vertebrate species in the wild.

 A routine DNA study has discovered that endangered female sawfish in Florida are producing offspring without first mating with males.
This 'virgin birth' process is known as parthenogenesis, and has previously been observed in certain shark, snake and fish species living in captivity. But this is the first time scientists have observed asexual reproduction occurring in a wild vertebrate species, which suggests the process could be more common in vertebrates than previously thought.
The discovery was made while researchers were examining the DNA of 190 smalltooth sawfish captured in southern Florida to find out if they were regularly breeding with their family members because of their smallpopulation size. "What the DNA fingerprints told us was altogether more surprising: female sawfish are sometimes reproducing without even mating," said lead author Andrew Fields from Stony Brook University in the US. In fact, one population of sawfish was made up of 3 percent parthenogenesis births.
The team found that seven of the female sawfish were born via parthenogenesis, after analysing 16 different sites on the individuals' genomes - the same technique that's used in human paternity tests.
So how exactly does an animal give birth without having sex? Parthenogenesis is a common process in invertebrates, but it's rare in vertebrates. It's thought to occur when an unfertilised egg absorbs a genetically identical sister cell, producing an offspring with two identical chromosomes. This means that it has around half the genetic diversity of regular, sex-produced offspring.
"There was a general feeling that vertebrate parthenogenesis was a curiosity that didn't usually lead to viable offspring," said one of the researchers, Gregg Poulakis from the Florida Fish and Wildlife Conservation Commission. But the seven virgin births found during this study all appeared to be perfectly healthy, and have now been tagged and released back into the wild. The team will continue to research the individuals, with the hopes of finding out whether they grow up to be fertile themselves.  
Smalltooth sawfish have been driven close to extinction over the past century due to overfishing and habitat degradation, and the global population is thought to be around just 1 percent of 1990 levels. The researchers now believe that the sawfish may be using parthenogenesis as way to help maintain their numbers during this critical period.
In the long-term, this parthenogenesis strategy will greatly reduce genetic diversity, leaving the species susceptible to new threats, such as disease and climate change. It also makes them vulnerable to any genetic mutations. But in the short-term, it might help them keep their numbers high enough to survive extinction. "This should serve as a wake-up call that we need serious global efforts to save these animals," said Feldheim.
The researchers have published their results in the journal Current Biology, and are now hoping to find signs of other endangered species using this strategy in the wild

Healthy skin cells harbour a high number of cancer-causing mutations And apparently, it's completely normal.


A quarter of healthy skin cells could harbour cancer-causing mutations resulting from Sun exposure, a new study by researchers in the UK suggests.

The finding offers clues about the transition of cells from a healthy to a cancerous state, and demonstrates how normal tissue analysis can provide clues about the origins of the disease.

It was previously thought that tumour-forming cell mutations were rare, and occurred just before the onset of cancer.

But this latest study, which examined healthy eyelid skin that was removed from four patients during cosmetic surgery, has revealed that these cancer-linked mutations "are staggeringly common in normal skin," one of the team, oncologist Philip Jones from the University of Cambridge, told Tina Hesman Saey at Science News.

The researchers performed ultra-deep gene sequencing on 234 biopsies of skin taken from the four patients, who were aged between 55 and 73. They were scanning for 74 known mutations.

They found that about 25 percent of skin cells carried at least one mutation linked to cancer. This equated to more than 100 potentially cancer-causing DNA mutations in every 1 square cm (0.1 square inch) of skin, which is roughly the size of a fingernail.

"The most surprising thing is just the scale, that a quarter to a third of cells had these cancerous mutations is way higher than we'd expect, but these cells are functioning normally," senior author Peter Campbell, head of cancer genetics at the Wellcome Trust Sanger Institute, told James Gallagher at the BBC.

Skin cancer is caused by overexposure to the Sun's radiation. The mutations observed in the analysed skin samples showed the patterns associated with the most common and treatable form of skin cancer, known as cutaneous squamous cell carcinoma, rather than the more lethal form, melanoma.

The team found that these mutated cells had grouped into clusters - or 'clones' - and had grown to be around twice the size of similar clusters consisting of normal cells.

But interestingly, none of the mutations uncovered had developed into cancer.

"The burden of mutations observed is high but almost certainly none of these clones would have developed into skin cancer," lead author, Iñigo Martincorena from the Wellcome Trust Sanger Institute, said in a press release.

"Because skin cancers are so common in the population, it makes sense that individuals would carry a large number of mutations. What we are seeing here are the hidden depths of the iceberg, not just the relatively small number that break through the surface waters to become cancer."

The findings, which have been published in the journal Science, could inform the development of new cancer drugs targeting changes in the cell-life cycle, and also highlight the importance of keeping your skin protected from sunlight.

"Whilst the body's immune system can prove quite effective at removing mutated cells, it is important to remember that some of cells aren't removed and mutate into cancers," Bav Shergill from the British Association of Dermatologists, who wasn't involved in the study, told the BBC. "Prevention is the first line of defence."

10 Apps For Best Use Of Ubuntu

Are you switching to Ubuntu or any other Linux product? Then it means more than a change in the operating systems and you must know that. You should know all the apps which will help you in this change. There are a lot of critical apps but we will be sharing 10 of them on which you can rely on.
Ubuntu, Linux, Ubuntu apps, 10 apps for Ubuntu, Firefox, Parcelite,  Bittorrent Sync,  System Monitor,  PulseAudioControl,  Skype,  Kdenlive, OpenShot,  Writer, SimpleScreenRecorder

Top 10 Reasons Why Java Programming Language Is A Must!

Java, considered one of the best programming languages ever, has so many reasons to become the favourite among developers. Java's popularity has been growing immensely and with new versions, performance has kept improving and Android app development has been made easier. In terms of job opportunities too, Java is the best language to learn. So here we will discuss the top ten reasons why Java language should be learnt anyhow, without any miss.
Java, Java programming language, Java language popularity, reasons why Java is important, Top 10 Reasons Why Java Programming Language is important, Object Oriented Programming language, Java libraries, Java development, Java applications

Reason #1:

Java is the programming language which can be learnt in the easiest way possible. Java's syntax is fluent and it makes it easy to read Java programme and learn it faster than other languages. If the learner gets familiar with installing JDK and setting up PATH, then it's easy to write programme in Java.

Reason #2:

Java is an Object Oriented Programming language and it also helps to keep system modular and flexible. If the key concept of OOPS is clear to you, then Java can help with its best practices and design patterns. Java promotes use of SOLID and Object oriented design principles in form of open source projects.

Reason #3:

Java has rich API and it's highly visible with Java installation. Java programming beginners usually code applets which provide animation capability. It also provides API for I/O, networking, utilities, xml parsing, database connection and more.

Reason #4:

Java has huge contribution by Eclipse and Netbeans and coding in IDE is a huge pleasure. DOS Editor and Notepad help in code completion and they also provide powerful debugging capability. Java development is made easier by IDE as IDEs make it easy to search, refactor and read codes too. Java platform has several tools for building Java applications too.

Reason #5:

Java can be used anywhere, thanks to open source libraries. Great libraries have come from Apache, Google and other similar organisations and Java development is made easier, faster and cost effective too.

Reason #6:

Java gets huge strength from communities as communities contribute a lot to share knowledge. Java has many active forums and these forums help Java beginners a lot.

Reason #7:

Cost is always an important factor for learning any language and as Java is a free language, you don't need to pay anything to create any Java application. Java is mostly popular for this reason and Java programmers are easily available for any enterprise too.

Reason #8:

Java has some great piece of documentation which discusses Java API and the method of coding with Java. With IDE, Javadoc doesn't require any browser now as it can be opened in an IDE window only.

Reason #9:

Java complies with every platform and this is one of the main reasons behind its popularity. Java's tagline itself proves how much exciting it can prove for any programmer - "write once run anywhere".

Reason #10:

Java is prevalent everywhere – on desktops, on mobiles and across every platform. Java programmers are highly available and that's why every organisation prefers Java to develop any new programme.

Five Reasons Why Big Data Will Be A Huge Hit In 2015!

Big Data has been one of the trending topics over last few years. Better yet, some companies have gained expertise in it. However there is still confusion about how to unlock business potential using Big Data. We are expecting to see companies explore and grab expertise in multiple domains related to Big Data in this year. Let’s take a look at five reasons why 2015 will be a hot year for Big Data.
big data, growth, data hacks, data science, big data, hadoop, Internet of Things, DevOps, Mobile Analytics, Security analysis, application performance monitoring, APM.

1. Security Analyst:

Analysts have played a key role in detecting and preventing threats last year. According to a recent survey, organization detects about the security attack after 200 days. Attackers get to access the victim’s network for over 200 days. In most cases, victim is informed about the attack by someone outside their organisation. Data Analysts need to be more aware and productive in order to spot the unusual event patterns and to prevent these security attacks. With the fast growing IT industry, network frauds are easy to spot but they are constantly changing. It is challenging for security analysts to manage these records. Writing security rules in software isn't enough these days, the nature of fraud patterns are constantly changing.

2. Hadoop:

Analysing the data stored in Hadoop in EMEA is time consuming and expensive. Some new tools will be introduced in 2015 which will make the analysis of data stored in Hadoop much more easier. Organisations will be able to gain business insights from Hadoop in real-time by opening organisation data to new audience. Number of organisations are testing new Hadoop solutions, which will bring some affordable solutions in 2015. Some leading companies like Amazon are also opting for PAYG (pay as you go) method for payment. Companies these days have freedom to experiment with Hadoop. The new approach of offering ‘Big Data as a Service’ will enable the small organisations to identify ROI and possible return on big investment.

3. IoT (Internet of Things):

We witnessed number of consumer products in field of IoT. 2015 is expected to bring innovations in IoT. Experts are expecting the conversion of IoT beyond consumer devices. Organisations are working on revolutionary tech products that will connect industries like manufacturing, transportation, construction with internet communication. Manufacturing is already benefiting from IoT and Big Data. If we link up sensors and robotics to automate processes, manufacturing industry will have a great benefit out of it. Manufacturing industry can become much more efficient if we generate machine data that can be indexed, monitored and analysed. Implementation of IoT in transportation can be used to contribute to Big Data which can help in changing strategy that the industry has been using for long time.

4. DevOps:

With the growing number of organisations, DevOps all drive the quality of software and delivery exactly what customers are looking for. DevOps can be very helpful in analyzing the data generated by interacting with customers. This analyzed data can be really helpful while releasing new web app, mobile app or a feature in existing apps. Companies can build strong DevOps (developer and IT operational analytics) team to predict the performance and identify issues. With the fast growing software product industry, DevOps are really important aspect of the company.

5. Mobile Analytics:

According to the survey statistics, 60 per cent of the traffic to e-commerce companies is from mobile devices. The mobile app is as valuable as websites these days. A customer experience on mobile applications is much more efficient as compared to web app. Developing a mobile app of great user experience will become essential part of 2015. Analytics will play pivotal role in both, helping retailers to trailer as well as a customer journey for mobile and spot usual event patterns that can lead to potential security threats. DevOps can also help in measuring APM (Application Performance Monitoring), this can predict application delivery cycle of apps.

Don’t Be Google..!!!!!!

Dear Google: what happened? Android sales are falling. Chrome has become a bloated hog. Analysts are calling you the new Microsoft, or, much worse, “the new Yahoo!” And most damning of all: you have squandered our trust. You used to be special, Google. Or at least we used to believe you were special. But you seem more and more like just another megacorporation.

 Does that sound harsh? Consider the Zoe Keating kerfuffle:

YouTube gave Keating a take-it-or-leave contract, some terms of which were unacceptable to her. Some of the terms were also pretty hard to understand […] As YouTube now explains it — following a public debate following Keating’s blog post — Keating has a relatively simple choice […] These responses go against descriptions of the agreement presented to Keating (and transcribed by her) by YouTube previously, and presumably represent an update to the contract’s terms.
 At best, Google is guilty of incredibly confusing and heavy-handed communication, something they have long been (rightly) accused of. At best. But, as Jamie Zawinski put it:

This sounds like Google using the same strategy they used with Google Plus: instead of creating a new service and letting it compete on its own merits, they’re going to artificially prop it up by giving people no choice but to sign up for it. Except in this case the people being strong-armed are the copyright holders instead of the end users. (So far, that is! Wait for it.)
 Consider “Never trust a corporation to do a library’s job“:

As Google abandons its past, Internet archivists step in to save our collective memory … Google Groups is effectively dead … Google News Archives are dead … Projects that preserve the past for the public good aren’t really a big profit center. Old Google knew that, but didn’t seem to care […] The desire to preserve the past died along with 20% time, Google Labs, and the spirit of haphazard experimentation.
 …or, as VICE puts it: “Google, a Search Company, Has Made Its Internet Archive Impossible to Search.”
 Consider “Google to shut down GTalk on February 16, will force users to switch to Hangouts“:

 Remember the good old days, a decade ago, when everyone admired everything Google did? What happened?
 …I believe I may have an answer or two to that question.

 Google has long been a bizarre swan of a company. To the casual eye, it’s a billion Android phones playing YouTube videos, its nonpareil search engine, plus its Google Xmoonshots and miracles, robot dogs rescued from the militarySpaceX funding rounds, etc, all cruising effortlessly along. Call that Awesome Google. But under the waterline, a gargantuan advertising machine paddles desperately, propelling Awesome Google towards its applause. Call that Mammon Google.
 For all those analysts cavils, Mammon Google is still a colossal money-making machine, and both it and Awesome Google employ thousands of the smartest people alive (including — disclaimer/disclosure — multiple personal friends.) I fully expect Google to overcome the business challenges it faces…
 …but I no longer expect to be particularly happy about this.
 We’ve all been conditioned to see Awesome Google, but of late, Mammon Google seems harder and harder to ignore. Why is this? There seems to be no need for this. Mammon is still pouring money into Awesome. So what happened to the golden glory-days Google we knew and loved?
 It’s true what Ben Thompson of Stratechery says: Google today is very reminiscent of Microsoft in the 90s. They too were the beneficiary of a seemingly endless, unassailable, firehose of money. But instead of spending that money on moonshots, Microsoft became a much-loathed corporate predator that wasted colossal amounts of time and money on infighting and horrors like Microsoft Bob and Windows Vista. Why has Google apparently taken a few steps down that cursed primrose path? Why is Mountain View in danger of becoming the new Redmond?
 Why indeed. It turns out that Google is literally the new Microsoft:

 (And we’re not just talking about low-level engineers here. Vic Gundotra, the former head of Google Plus, was a former Microsoft executive; which kind of explains a lot.)
 This may help to explain why Google is, I believe, slowly but steadily losing our trust. Nowadays, when you interact with Google, you don’t know if you’ll be talking to Awesome Google; Mammon Google; …or a former Microsoftian whose beliefs and values were birthed in Redmond, and who, as a result, identifies a whole lot more with Mammon — and with bureaucratic infighting — than with Awesome.
 Say what you like about Apple, and I can complain about them at length, you always know what to expect from them. (A gorgeous velvet glove enclosing an exquisitely sleek titanium fist.) But Google seems increasingly to have fragmented into a hydra with a hundred tone-deaf heads, each with its own distinct morality and personality. That wouldn’t matter so much if trust and awesomeness — “don’t be evil!” “moonshots!” — weren’t so intrinsic to the Google brand … which, to my mind, gets a little more tarnished every year.

New app lets you control exactly how much energy each appliance uses

Australia's national science organisation, the CSIRO, has developed a new app that lets you remotely keep track of exactly how much money you're spending on electricity at any given time - and even lets you monitor and control individual appliances from your phone.
While we can already stay on top of how much electricity our houses are guzzling on a daily basis using smart meters, the new prototype app - which is called 'Eddy' - wants to take things one step further by putting people in control of their power consumption, with the overall aim of saving people money and reducing greenhouse gas emissions.  

Right now the app only works on big devices such as air conditioners and pool pumps, but the developers are hoping that in the future they'll be able to take it down to the level of monitoring and turning on and off individual lightbulbs.
