Mars had become a point of concentration for all the living Beings. Well it is considered to be a living planet too.But here are some of the facts that you have to know about mars if you really care about it.

1)Mars is only about half diameter of the Earth-We think that Mars may be enough to occupy all the humans but not so . It is only half of the diameter of the earth . Well dont mind only half portion of your body can adjust through it ...
2)The Gravity on Earth is triple than that of Mars-Well it is a simple true that mars gravity is one third of the Earth's. You cant come onto ground again if you jump hard.
3)Mars is somrtimes closest planet to the Earth- SOmetimes since the orbit of mars falls laterally it becomes the closest planet to the Earth and we can have ome clear view of it through our naked eyes or telescope.
4)Mars has two moons- Moon the natural satellite of Earth gets double in number if you go to Mars and you can se two moons at a time . How Good Vision!!
5) The surface of Moon is Extremely Cold/Hot- The temperature on the surface of the monn is not fixed. It nmay be more ant the day time and freezing cold at the night time  due to absence of Sun's Rays.

Nearly three percent of the world's oceans – an area slightly larger than Europe – now lies within designated marine protected areas, according to new data from the International Union for Conservation of Nature (IUCN). This is a significant increase from 2010 when the area protected was just 1.2 per cent. However, many of the new protected zones may be of little value in terms of conservation.

The IUCN, which yesterday released the latest official map of marine protected areas (MPAs), defines a protected area as "a clearly defined geographical space, recognised, dedicated and managed, through legal or other effective means, to achieve the long-term conservation of nature with associated ecosystem services and cultural values". In practical terms, this can mean implementing measures to restrict the amount of fishing and mineral exploitation that can take place in the waters, for example.

The rapid increase in coverage of MPAs means that the world should soon be able to meet the UN Convention on Biological Diversity target of having 10 per cent of the oceans protected. "It's encouraging to see the progress we've made so far," said Carl Gustaf Lundin, director of the IUCN's Global Marine and Polar Programme. "If we continue to increase this area by one per cent each year, we should be able to reach the agreed 10 per cent by 2020."
Antarctic talks

We may get even closer to meeting the target when the results of negotiations to create huge marine reserves around Antarctica – which would include some of the world's last remaining pristine waters – are announced next week. The MPAs being discussed in Hobart, Australia, would introduce a ban on fishing in the spawning areas of some species and put limits on the amount of fish caught elsewhere. If the proposals being discussed are agreed on, the global protected area will jump by about another percentage point.

But a preoccupation with the size of MPAs is counterproductive, says marine conservationist Bob Pressey from James Cook University in Townsville, Australia. "It's the wrong measure." He says conservation only occurs when a threat, such as species loss from overfishing or pollution, has been mitigated. Many of the protected areas do not enjoy sufficient enforcement.

The largest network of marine reserves in the world is around Australia, and was significantly added to in 2012. Pressey points out that many of those areas allow oil and gas exploration, while others allow recreational fishing.
Motivated by numbers

The focus on the 2020 target means governments are motivated to protect the low-hanging fruit – large areas that are of little conservation value or that are not under any threat, Pressey says.

"If you look at the no-take zones [off Australia], you find them way offshore in deep water and you find them in areas with no oil or gas interest," he says. "In the world map, we see a repetition of that. The big MPAs are remote as hell," he says.

Hugh Possingham from the University of Queensland, who together with Pressey built the open-source software that countries use to design MPAs, agrees. "We don't want countries just bragging about the size and percentages. There's more to this than size," he says. One important factor is that an example of each type of ecosystem in a country's waters should be protected, such as mangrove forests or salt marshes, but this effort is often perverted by commercial interests, he says.

Pressey says the Antarctic MPAs currently being negotiated would be a valuable addition because of the region's important biodiversity – the Ross Sea, for example, boasts orcas, minke whales, seals, Adélie and emperor penguins – and the threat the area faces from overfishing.

Time is an illusion – at least in a toy model of the universe made of two particles of light. The experiment shows that what we perceive as the passage of time might emerge from the strange property of quantum entanglementMovie Camera. The finding could assist in solving the long-standing problem of how to unify modern physics.

Physicists have two ways of describing reality, quantum mechanics for the small world of particles and general relativity for the larger world of planets and black holes. But the two theories do not get along: attempts to combine their equations into a unified theory produce seemingly nonsensical answers. One early attempt in the 1960s was the Wheeler-DeWitt equation, which managed to quantise general relativity – by leaving out time altogether.

"It means that the universe should not evolve. But of course we see evolution," says Marco Genovese at the National Institute of Metrological Research in Torino, Italy.

In 1983 theorists Don Page and William Wootters suggested that quantum entanglement might provide a solution to the Wheeler-DeWitt "problem of time"Movie Camera. When quantum objects are entangled, measuring the properties of one changes those of the other. Mathematically, they showed that a clock entangled with the rest of the universe would appear to tick when viewed by an observer within that universe. But if a hypothetical observer existed outside the universe, when they looked in, everything would appear stationary.
Photon clock

For the first time, Genovese and colleagues have demonstrated this effect in a physical system, albeit in a "universe" that contains only two photons. The team started by sending a pair of entangled photons along two separate paths. The photons start out polarised, or orientated, either horizontally or vertically, and the polarisation rotates as both photons pass though a quartz plate and on to a series of detectors.

The entangled photons exist in a superposition of both horizontal and vertical states simultaneously until they are observed. But the thicker the plate, the longer it takes the photons to pass through and the more their polarisation evolves, affecting the probability that either one will take a particular value.

In one mode of the experiment, one of the photons is treated like a clock with a tick that can alternate between horizontal and vertical polarisation. Because of entanglement, reading this clock will affect the polarisation value of the second photon. That means an observer that reads the clock influences the photons' universe and becomes part of it. The observer is then able to gauge the polarisation value of the other photon based on quantum probabilities.

Since photons passing through a thicker quartz plate experience a different degree of change, repeating the experiment with plates of different thicknesses confirms that the second photon's polarisation varies with time.

In another mode, the experimenter is a "super-observer" that exists outside of the universe, and so measures the quantum state of the system as a whole. From that vantage point, the state of both photons taken together is always the same, giving the appearance of a static universe.
Quantum cosmos?

"It's very nice these people have done an experiment to illustrate this effect and show how in practice it can occur," says Page, who is now at the University of Alberta in Edmonton, Canada.

But not everyone thinks the Wheeler-DeWitt equation is the correct route to unification of the quantum and classical worlds, says Lee Smolin at the Perimeter Institute in Waterloo, Ontario, Canada. "They have verified in the context of a laboratory system that quantum mechanics is working correctly," he says. But Smolin argues that any correct description of the universe must include time.

Genovese acknowledges that the result does not cinch the issue. Instead, he sees the work as a hint that quantum equations can in some ways mesh with general relativity, offering hope for a unified theory. The next step will be moving beyond the toy universe and seeing whether a similar effect scales up to explain what we see on a cosmic level.

"It's a visualisation of the phenomenon, it's not a proof," Genovese says of the experiment. "You should look to the universe itself for that."

 US and British intelligence agencies have successfully cracked much of the online encryption relied upon by hundreds of millions of people to protect the privacy of their personal data, online transactions and emails, according to top-secret documents revealed by former contractor Edward Snowden.

The files show that the National Security Agency and its UK counterpart GCHQ have broadly compromised the guarantees that internet companies have given consumers to reassure them that their communications, online banking and medical records would be indecipherable to criminals or governments.

The agencies, the documents reveal, have adopted a battery of methods in their systematic and ongoing assault on what they see as one of the biggest threats to their ability to access huge swathes of internet traffic – "the use of ubiquitous encryption across the internet".

Those methods include covert measures to ensure NSA control over setting of international encryption standards, the use of supercomputers to break encryption with "brute force", and – the most closely guarded secret of all – collaboration with technology companies and internet service providers themselves.

Through these covert partnerships, the agencies have inserted secret vulnerabilities – known as backdoors or trapdoors – into commercial encryption software.

The files, from both the NSA and GCHQ, were obtained by the Guardian, and the details are being published today in partnership with the New York Times and ProPublica. They reveal:

• A 10-year NSA program against encryption technologies made a breakthrough in 2010 which made "vast amounts" of data collected through internet cable taps newly "exploitable".

• The NSA spends $250m a year on a program which, among other goals, works with technology companies to "covertly influence" their product designs.

• The secrecy of their capabilities against encryption is closely guarded, with analysts warned: "Do not ask about or speculate on sources or methods."

• The NSA describes strong decryption programs as the "price of admission for the US to maintain unrestricted access to and use of cyberspace".

• A GCHQ team has been working to develop ways into encrypted traffic on the "big four" service providers, named as Hotmail, Google, Yahoo and Facebook.

 New claims emerged last night over the extent that US intelligence agencies have been monitoring the mobile phone of Angela Merkel. The allegations were made after German secret service officials were already preparing to travel to Washington to seek explanations into the alleged surveillance of its chancellor.a

A report in Der Spiegel said Merkel's mobile number had been listed by the NSA's Special Collection Service (SCS) since 2002 and may have been monitored for more than 10 years. It was still on the list – marked as "GE Chancellor Merkel" – weeks before President Barack Obama visited Berlin in June.

In an SCS document cited by the magazine, the agency said it had a "not legally registered spying branch" in the US embassy in Berlin, the exposure of which would lead to "grave damage for the relations of the United States to another government".

From there, NSA and CIA staff were tapping communication in Berlin's government district with high-tech surveillance. Quoting a secret document from 2010, Der Spiegel said such branches existed in about 80 locations around the world, including Paris, Madrid, Rome, Prague, Geneva and Frankfurt. Merkel's spokesman and the White House declined to comment on the report.

The nature of the monitoring of Merkel's mobile phone is not clear from the files, Der Spiegel said. It might be that the chancellor's conversations were recorded, or that her contacts were simply assessed.

Ahead of the latest claims , the German government's deputy spokesman, Georg Streiter, said a high-level delegation was heading to the White House and National Security Agency to "push forward" investigations into earlier surveillance allegations.

Meanwhile several thousand people marched to the US Capitol in Washington yesterday to protest against the NSA's spying programme and to demand a limit to the surveillance. Some of them held banners in support of Edward Snowden, the former CIA contractor who revealed the extent of the NSA's activities.

The march attracted protesters from both ends of the political spectrum as liberal privacy advocates walked alongside members of the conservative Tea Party movement.

The delegation will include senior officials from the German secret service, according to German media reports.

Germany and Brazil are spearheading efforts at the UN to protect the privacy of electronic communications. Diplomats from the two countries, which have both been targeted by the NSA, are leading efforts by a coalition of nations to draft a UN general assembly resolution calling for the right to privacy on the internet. Although non-binding, the resolution would be one of the strongest condemnations of US snooping to date.

"This resolution will probably have enormous support in the GA [general assembly] since no one likes the NSA spying on them," a western diplomat told Reuters on condition of anonymity. The Brazilian president, Dilma Rousseff, had previously cancelled a state visit to Washington over the revelation that the NSA was scooping up large amounts of Brazilian communications data, including from the state-run oil company Petrobras. The drafting of the UN resolution was confirmed by the country's foreign ministry.

The Associated Press quoted a diplomat who said the language of the resolution would not be "offensive" to any nation, particularly the US. He added that it would expand the right to privacy guaranteed by the international covenant on civil and political rights, which went into force in 1976.

The draft would be sent next week to the general assembly subcommittee on social, humanitarian, cultural and human rights issues, and be put to the full general assembly in late November.

Germany and France demanded on Thursday that the Americans agree to new transatlantic rules on intelligence and security service behaviour by the end of the year. Merkel added that she wanted action from Obama, not just apologetic words.

British and US civil liberties groups on Saturday added their voices to the criticism of snooping by both UK and US intelligence services after the Guardian revealed that the British intelligence agency GCHQ repeatedly said it feared a "damaging public debate" on the scale of its own activities.

Shami Chakrabarti, the director of Liberty, and Anthony Romero, executive director of the American Civil Liberties Union, issued a joint statement, saying: "The Guardian's publication of information from Edward Snowden has uncovered a breach of trust by the US and UK governments on the grandest scale. The newspaper's principled and selective revelations demonstrate our rulers' contempt for personal rights, freedoms and the rule of law.

"Across the globe, these disclosures continue to raise fundamental questions about the lack of effective legal protection against the interception of all our communications. Yet in Britain that conversation is in danger of being lost beneath self-serving spin and scaremongering, with journalists who dare to question the secret state accused of aiding the enemy.

"A balance must of course be struck between security and transparency, but that cannot be achieved while the intelligence services and their political masters seek to avoid any scrutiny of, or debate about, their actions."

"The Guardian's decision to expose the extent to which our privacy is being violated should be applauded and not condemned."

Nick Pickles, director of Big Brother Watch, said the fact GCHQ had doubts about the legality of its surveillance "reinforces the public interest in the disclosures about what has taken place in America and closer to home

"Parliament never legislated to allow the scale of interception that has been exposed, with laws written long before widespread broadband internet access or Facebook existed. There is a clear and overwhelming need for a fundamental review of our legal framework."

"If companies are handing over customer data or access to their equipment when there is no legal authority, then those businesses may well have broken the law. This should be urgently investigated by the information commissioner."

Defending the NSA's actions, the US administration has insisted that it is necessary to intercept vast amounts of electronic data to effectively fight terrorism, but the White House has said it is examining countries' concerns as part of an ongoing review of how the US gathers intelligence.

Britain may recruit ex-hackers as reservists working in a UK cyber defence force. Photograph: Daniel
Convicted hackers could be recruited to the UK'S new cyber defence force, the defence secretary has said.

Philip Hammond announced plans for the unit last month, declaring it would have the capability to mount cyber attacks against other countries as a means of deterring them from striking against Britain.

Hundreds of computer experts will be recruited as reservists, trained with the help of GCHQ's joint cyber unit at Cheltenham, and, asked if they could include convicted hackers among their ranks, Hammond said it was a possibility.

"As a matter of policy, the armed forces don't necessarily exclude people who have criminal convictions," he told BBC Newsnight. "Each individual case would be looked at on it's merits. The conviction would be examined in terms of how long ago it was, how serious it was, what sort of sentence had followed. So I can't rule it out."

Hammond was asked for his views after the head of the new unit, Lieutenant Colonel Michael White, had responded positively, when the same question was put to him.

"I think if they could get through the security process, then if they had that capability that we would like, then if the vetting authority was happy with that, why not?" he said.

With many of the belief that there is a deficit of cybersecurity experts in the UK, the hiring of hackers could help plug the gap. A survey of IT professionals last month found that 70% believed businesses should hire ex-hackers to safeguard and improve online security. In the US, it is already common practice, with many companies recruiting at hacker conventions.

Last year, the UK's cyber defences blocked around 400,000 "advanced, malicious cyber threats" to the government secure intranet alone, according to Hammond. British ministers have not publicly named the culprits partly because it is so difficult to prove who exactly are behind cyber attacks but privately officials point the finger at Russia and China.

The defence secretary has said the new £500m unit could disable enemy communications, nuclear and chemical weapons, planes, ships and other hardware. He told Newsnight that there would be flexibility around recruitment criteria, for example in areas such as fitness, as it would be unnecessary for someone employed in cyber security to show the same physical fitness standards as other members of the armed forces.

यसअघि पनि पृथ्वी ध्वस्त हुनै लागेका विभिन्न खाले भविष्यवाणी तथा समाचार आएपनि कसैले दाबी
प्रमाणित गर्न सकेनन् र पृथ्वी ध्वस्त भएन । त्यसैले पृथ्वी ध्वस्त हुने भन्ने भविष्यवाणीलाई मानिसहरुले हावादारी भन्न थालेका छन् । तर पछिल्लो पटक भने पृथ्वी ध्वस्त हुने बारेको वैज्ञानिक भविष्यवाणी नै र्सार्वजनिक भएको छ ।
अमेरिकी अन्तरीक्ष संस्था नासाका अनुसार सन् २८८० को मार्च १६ का दिन पृथ्वीमा ठूलो प्रलय हुने खतरा छ । उसका अनुसार उक्त दिन १९५० डीए नामको क्षुद्रग्रह पृथ्वीसँग ठोक्किने खतरा छ ।

झण्डै एक माइल ब्यास भएको उक्त क्षुद्रग्रह १५ किलोमिटर प्रति सेकेण्डको बेगमा पृथ्वीतर्फआइरहेको छ । सोही गति तथा दिशा कायम रहेमा यो क्षुद्रग्रह उक्त मितिमा पृथ्वीसँग ठोक्किनेछ र त्यस क्रममा ४४ हजार ८ सय मेगाटन टिएनटी नामक विस्फोटक पदार्थ विस्फोटन हुँदा जत्तिकै उर्जा उत्पन्न हुनेछ ।
नासका अनुसार यो क्षुद्रग्रह पृथ्वीसँग ठोक्किने र क्षति पूराउने खतरा ०.३ प्रतिशत मात्र छ । तथापि यसको यो खतराको अनुपात यसअघिका क्षुद्रग्रहको खतरा भन्दा ५० प्रतिशत बढि हो ।
स्मरण रहोस् यस्तै खाले क्षुद्रग्रह पृथ्वीसँग ठोक्किँदा ६ करोड ५० लाख वर्षपहिले पृथ्वीबाट डाइनोसर लोप भएको थियो ।
पृथ्वीमा भविष्यमा ठोक्किने खतरा रहेको भनिएको १९५० डिए क्षुद्रग्रह सन् १९५० मा पहिलोपल्ट देखा परेको थियो । त्यसबेला १७ दिन देखा परेर क्षुद्रग्रह हराएको थियो र आधा शताब्दीपछि सन् २००० को डिसेम्बर ३१ मा फेरि देखा परेको थियो ।
यो क्षुद्रग्रहको परिक्रमण दर २.१ घण्टा रहेको छ जुन क्षुद्रग्रहमा दोश्रो उच्च गति हो । वैज्ञानिकहरुका अनुसार अहिले ब्रम्हाण्डमा १४ सय वटा यस्ता जोखिमपर्ूण्ा क्षुद्रग्रह छन् जसले पृथ्वीमा असर पूराउने खतरा छ ।

Have you noticed that your computer runs slower than before? Or just slowly in general? Try these strategies to make your Windows or Mac computer run faster.

 1    Check your hard disk space. As a rule, you want to keep at least 15% of the hard disk space free to keep the computer running smoothly. Simply go to My Computer, right-click on Hard Drive, and go to Properties. There you'll see a pie chart of your free versus used space. If it’s mostly full, you'll want to start by removing unnecessary programs and files; if it’s not, you probably want to tackle the actual way your computer operates.
    2    Remove any programs you do not use. Go to Control Panel > Add or Remove Programs (or Uninstall a Program, depending on your operating system) to find a master list of programs installed on your computer. Some things will strike you as useless immediately, in which case you can remove them right away. Others won’t look familiar to you and may require you some research.
        It may help to see how often you use the program. If you right-click one of the column titles above your program list (ex. Name, Publisher, Size, Installed On, etc.), you should be able to add additional characteristics by which to judge your programs. For example, find Last Used On on the list of options and check it; a column displaying the last time you used each program will now appear and can also be used to sort your programs. Some programs will not have been used in years and may be candidates for deletion.
        When in doubt, don't remove anything you don’t recognize; it may be critical to the function of your computer – and if you delete twelve different things only to discover that your computer no longer works properly, it will be very difficult to determine where exactly you went wrong.
        Don't forget to empty your recycling bin.
    3    Prevent unnecessary programs from starting when the computer boots. The more programs try to run while your computer initializes, the slower everything will be. Revise your startup programs by altering your system configuration via MSConfig.
    4    Install an anti-virus program, spyware scanner, and an anti-malware. The fewer bugs, viruses, and bits of adware your computer has to manage, the more time it will have to devote to other processes. While you're at it, make a point of keeping Windows up-to-date; not only will this keep Windows itself in better shape, but some viruses ride in on Windows updates that are downloaded way after the fact (and therefore not monitored as closely).
    5    Run a Disk Cleanup. This can clean up hundreds of megabytes of temporary files – sometimes even gigabytes (if you have Windows XP, Vista, or 7). It will also open a window in which you can chose what to delete. Go to My Computer, right-click the Hard Drive and select Properties, and then click Disc Cleanup (within the General tab). Check all the boxes except for the game files and setup files.
    6    Run a Disk Defragment. This will reconfigure the way the hard drive stores information for maximum efficiency. Go to My Computer, right-click the Hard Drive and select Properties, then go to the Tools tab and click Defragment Now.
    7    Check for any disk errors. These will also slow your computer down. Go to My Computer, right-click the Hard Drive and select Properties, then go to the Tools tab and click Check Now under the Error-Checking area. When the dialogue box opens, check both boxes.
        If you get a window saying that Windows can't check the disk while it's in use, click on Schedule Disk Check and then OK. It will run on your next reboot.
    8    Turn off indexing. Go to My Computer, right-click the Hard Drive and select Properties, then unclick the box indicating that the drive should be indexed. Don't do this if you actually use any of the Windows Search functionality. The background indexing is what makes those searches fast and Windows is already very good about not getting in your way to do indexing while you're trying to do something else.
    9    Clear your Prefetch folder. Windows saves a file of the program you are using to make it start up faster. After years of use, this folder gets stuffed with irrelevant programs.
        Open Notepad and type:
        del C:\Windows\Prefetch\*.* /Q
        Rundll32.exe advapi32.dll,ProcessIdleTasks
        (Copy and paste this text to ensure you don’t make any mistakes.)
        Save as faster.bat (the .bat extension will run it as a batch file).
        Run it! Simply double-click the file to initialize. In a few moments, the command prompt will disappear and your programs should run more smoothly.
    10    Change Prefetch Parameters. This a dangerous task to complete unless you follow these steps exactly. If you're not sure about anything, don’t continue.
        Go to Start > Run and type regedit to initialize the registry editor.
        Go to HKEY_LOCAL_MACHINE>SYSTEM>CurrentControlSet>Control>Session Manager>Memory Management>Prefetch Parameters to access the parameters.
        Double-click EnablePrefetcher. Once the new window pops up, there should be a small, editable text box with the number 3 in it. (Windows allows 4 options: 0, 1, 2 and 3.) 3, the default, fetches everything.
        Change this to 2. Your PC will boot a lot faster and your PC performance shouldn't be affected.
        Click OK and then close regedit.
    11    Add RAM to your computer. To see if you need more RAM, initialize the Windows Task Manager by pressing CTRL+ALT+DELETE. Under the Performance tab, find the area devoted to Physical Memory. If the Free amount hovers around zero but the computer is still slow, you may need to take your computer in to add RAM or even add more RAM yourself.
    12    Restart your computer. The computer usually needs to reboot to implement changes.
    13    Remove gadgets you don't use. All gadgets that are running slow down your computer.
    14    Log off the users who do not want the computer. Switch user your account then if you see that many users are logged in, log them off.
