Google's New CEO, Sundar Pichai


sundar pinchai

Google just announced some huge changes to its executive structure.

Larry Page will run a completely new company called Alphabet, a collection of Google companies including Life Sciences, which manufactures glucose-sensing contact lenses, and Calico, which focuses on longevity. Sergey Brin will serve as Alphabet's President. 
Former Chrome and Android head Sundar Pichai will be Google's CEO.

Many are still unfamiliar with Google's new chief executive, who first joined Google in 2004 and eventually worked his way up to be Page's right-hand man.

Originally from Tamil Nadu, one of India's 29 states, Pichai studied at the Indian Institute of Technology Kharagpur, where he received a Bachelor of Technology.

He then received a M.S. from Stanford and obtained an MBA from Wharton School at the University of Pennsylvania. At Wharton, Pichai was honored as a Siebel Scholar and a Palmer Scholar.

Before his first job at Google, Pichai worked at Applied Materials as an engineer and then at McKinsey & Company in management consulting.

Sundar Pichai was put in charge of Android in 2013. 

In 2004, Pichai joined Google as its vice president of product management, where he led the team working on Google's Chrome browser and operating system.

Pichai quickly began to receive more responsibility, however, taking on involvement with various Google search products including Firefox, Google Toolbar, Desktop Search, Gadgets, and Google Gears and Gadgets.

In September 2008, Pichai oversaw the successful launch of the Chrome web browser, and less than a year later, the web-based Chrome operating system for netbooks and desktop computers.

Pichai added another Google division to his portfolio in 2012 after Google Apps head Dave Girouard departed to start his own company, Upstart.

A year later, Pichai was put in charge of Android after Android co-founder and CEO Andy Rubin stepped down in March 2013.

Throughout his time at Google, Pichai has developed a sterling reputation for being well-liked, leading Recode's Kara Swisher to call his recent promotion "a definitive case of nice guys finish first."

Former Google product manager Chris Beckmann spoke highly of Pichai in a recent Quora post, praising Pichai's ability to helm difficult projects while building a strong team.

"He recruited, mentored, and retained a great team," said Beckmann. "Sundar's team of product managers had a reputation as being among the best of the best, similar to the reputation of the software engineers within Search Quality."

Beckmann also mentioned that Pichai "avoided making enemies" in the midst of Google's workplace politics and "navigated those politics to make his team successful while inflicting the least possible damage on any other team."

Pichai demonstrated his team devotion while working under Marissa Mayer, who then was a key executive at Google. According to The Information's Amir Efrati, Pichai "used to wait for hours outside her office to make sure that she gave his team solid work-performance scores."

In addition to his team management skills, Efrati notes that Pichai has also been known to throw his weight around when necessary. At his year's Consumer Electronics Show in Las Vegas, Pichai reportedly "told Samsung's mobile-products leader that Google was willing to 'walk away' from its enormous phone partnership with the company."

Pichai's impressive track record at Google caused him to be approached by Twitter to potentially lead Product at the social network, but Pichai ultimately declined. In addition to Twitter's interest, Pichai's name was also mentioned as a potential front-runner for the position of Microsoft CEO after Steve Ballmer announced his resignation in August 2013.
In October 2014, Google announced that Page would be stepping back to focus "on the bigger picture," according to Recode, and that Pichai would take on a larger role as a result.

Pichai took charge of Google's core products, including search, maps, research, Google+, Android, Chrome, infrastructure, commerce and ads, and Google Apps.

Introduction to 5G Technology

Even as 4G mobile telecommunication standards slowly gain in popularity, there is already talk of the fifth-generation or 5G standards that will further enhance communications on the move.

Dr J.D. Jain

   
5G mobile telecommunication standards stand for  fifth-generation advancements made in the mobile communications field. These comprise packet switched wireless systems using orthogonal frequency division multiplexing (OFDM) with wide area coverage, high throughput at millimetre waves (10 mm to 1 mm) covering a frequency range of 30 GHz to 300 GHz, and enabling a 20 Mbps data rate to distances up to 2 km. The millimetre-wave band is the most effective solution to the recent surge in wireless Internet usage. These specifications are capable of providing ‘wireless world wide web’ (WWWW) applications.

The WWWW allows a highly flexible network (flexible channel bandwidth between 5 and 20 MHz, optimally up to 40 MHz), and dynamic ad-hoc wireless network (DAWN). This technique employs intelligent antennae (e.g., switched beam antennae and adaptive array antennae) and the flexible modulation method, which helps in obtaining bidirectional high bandwidth, i.e., transfer of a large volume of broadcasting data in giga bytes, sustaining more than 60,000 connections and providing 25 Mbps connectivity.

Users of 5G technology can download an entire film to their tablets or laptops, including 3D movies; they can download games and avail of remote medical services. With the advent of 5G, Piconet and Bluetooth technologies will become outdated. The 5G mobile phones would be akin to tablet PCs, where you could watch TV channels at HD clarity without any interruption.

Key concepts in 
5G technology
Future mobile devices equipped with 5G technology will have:

  1. Wearable devices with artificial intelligence (AI)
  2. Internet Protocol version 6 where the IP address is assigned according to location and the connected network.
  3. The ability to connect the user to different wireless access technologies, like 2.5G, 3G, 4G or 5G mobile networks, as well as Wi-Fi and WPAN (wireless personal area network)—or even any other technology to be developed in the future. This is basically a concurrent data transfer path technique.
  4. Smart radio. In order to share the same spectrum efficiently during a wireless transmission scheme, the system will adaptively find (search) unused spectrum. This dynamic radio resource management will be achieved in a distributed fashion and rely on software defined transmission.
  5. High altitude stratospheric platform station (HAPS) system. This is based on beam division multiple access (BDMA) and group relay techniques.
5G hardware
Ultra wideband networks (UWB). It is already known that Wi-Fi, Wi-Max and cellular wide area communications are long-range radio technologies. But systems like WPAN need short-range radio technology, which helps in achieving higher bandwidths (around 4000 Mbps) but at low energy levels (UWB network) for relaying data from host devices to devices in the immediate vicinity, i.e., distances of around 10 metres or so. This higher bandwidth (4000 Mbps) level is almost 400 times faster than today’s wireless networks. Each network will be responsible for handling user-mobility while the user terminal will make the final choice among different wireless/mobile access network providers for a given service. However, there should be different radio interfaces for each radio access technology (RAT) in the mobile terminal.

Smart antennae. These include the following:
  1. Switched beam antennae. This type of antenna supports radio positioning via angle of arrival (AOA). Information is collected from nearby devices.
  2. Adaptive array antennae (Samsung has used 64 antennae elements). Such antennae promise to improve the capacity of wireless systems by providing improved safety through position-location capabilities. This technique rejects interference through spatial-altering-position location through direction-ending measurements and developing improved channel models through angle-of-arrival channel sounding measurement.
  3. CDMA (code division multiple access) technique. This technique converts audio analogue input signals into digital signals (ADC) in combination with spread spectrum technology. The signal is transmitted using modulation according to some predefined code (pattern), and is demodulated using the same pattern since there can be billions of code patterns which can provide privacy and sufficient security.
5G software
  1. 5G will be a single unified IP standard of different wireless networks and a seamless combination of broadband, including wireless technologies, such as IEEE802.11, LAN, WAN, PAN and WWWW.
  2. 5G will enable software-defined radio, packet layers, implementation of packets, encryption flexibility, etc. 
Chronological evolution of mobile technologies
Although the 1G system (NMT) was introduced in 1981, 2G (GSM) started to come out in 1982, and 3G (W-CDMA)/FOMA first appeared in 2001, the complete development of these standards (e.g., IMT-2000 and UMTS) took almost 10 years. It is still unclear how much time it will take to launch the standards for 5G.

5G technology will ensure the convergence of networks, technologies, applications and services, and can serve as a flexible platform. Wireless carriers will have an opportunity to shorten their return-on-investment periods, improve operating efficiency and increase revenues. In short, this will change people’s lives in numerous ways.

Internet Going to Crash in 8 Years...?

As the rapid increase in the usage of Internet day by day all over the world, some of the experts in Britain alerts that the Internet is going to be crashed in the span of 8 years. They said that One of the probable reasons of this is excess usage of internet is almost near to the limits and those limits cannot be increased.

Prof. Andreyales said "The Capability of Fiber optics, Cables used for data transfer for the gadgets such as Smart Phones, Tablets and Laptops will reach the highest limit point. So from the fiber cable we cant transfer data beyond the highest limit." Prof. Andreu is going to conduct a meeting related to the measures taken for this issue on 11th this month.

7 Tips for Creating Posts That Will Spread on Social Media


1. Write something that everyone can follow.

Your first goal in creating a post that has the potential to go viral on social media is to make the content easily consumable by the largest audience possible. This means you need to cater to beginners, intermediate, and advanced level readers in your industry – all in the same post!
If your post is a tutorial, for example, you need to write it in a way that someone new to the process could get started easily with your directions while also including tips and tricks that people who are familiar with the process might not have learned yet.
Content that goes viral does so for a reason – because everyone who comes in contact with it loves it enough to keep the spread happening. Try to ensure that your content will touch base with every reader possible!

2. Make sure your post is complete.

You’ve seen them – the kinds of posts where, after you’ve read it, your next goal was to find out more information. You probably didn’t think to share the post – you just went in search of more details.
This is where the little 300 word, made for SEO posts generally fail. They’re generally too simplistic to the point that they don’t actually give the reader everything they need to be satisfied.
You want your post to be the full guide. You want it to answer everyone’s question before they even get a chance to ask it. You want it to be something that others will think of sharing when someone asks them about that topic. You want it to be memorable.

3. Bring a new concept to life, or tackle it from a different angle.

It’s tough, I know. Most industries are over saturated with content to the point that it doesn’t feel like there is anything new left to offer. But I assure you, there is.
Social media ROI is one of those topics. Everyone writes about it, or so it seems. I read through a lot of posts on the subject, and I came to the conclusion that most posts out there either said it was impossible to determine or only gave you half the steps to start measuring it.
So I wrote what I felt no one else had – a post on how to measure as much of it as you can using Google Analytics. I also kept points #1 and #2 in mind, and voila – with some nice promotional (see killer awesome post promotion process) in two weeks it amassed 1,100+ tweets, 500+ likes, 2,600+ stumbles, 350+ shares on LinkedIn, and at least 100 comments (not counting my author responses) which is not too shabby I’d say.

4. Focus on the network you are targeting.

What if your goal isn’t to have widespread social media coverage, but to do well on one particular social network? Maybe you just want a ton of tweets, a lot of shares, or simply to hit the front page of Digg or a similar network. The key in this case is to keep the above two tips in mind and write your post on that network.
If you enter a contest where the winner is based on the number of tweets, then your task is simple – write a great post on Twitter. Your goal, again, is to keep in mind previously mentioned points #1 – #3. If you have a post that everyone on Twitter can benefit from, that is thorough, and has some unique aspects to it, you can almost be certain that, with the right amount of promotion, that post will make retweet history!

5. Create a mega-list.

While there are definitely some list-haters out there, the consensus is that if you create an awesome list, you’re going to get a lot of awesome social shares. The key to lists, of course, is to make them unique and include lots of valuable information that others don’t.
When it comes to top blog lists, don’t just say “here’s 50 blogs I like” and list them in bullet points. Write a nice description of them, and even include a link to a few of their latest posts. The latter point is key – linking to a blogger’s latest posts will send many of them a trackback which alerts them to the fact they were listed. Sharing at that point takes care of itself – if you have 20 people in a list, most of them will be happy to spread the word that they’ve been recognized for their blogging accomplishments.
If your list doesn’t involve blog posts and track backs, your next goal once it goes live is to make sure everyone on the list knows about it. I prefer tagging people in a Facebook update, tweeting them, or emailing them, depending on our relationship. You can also do tweets like the following.
Check out the Top 10 Twitter Apps including @HootSuite @BufferApp @TweetDeck @CoTweet @Bitly http://bit.ly/q5u1Qr
These will alert individuals and/or brands to the fact that they have been listed so that they will hopefully give you some love from their social accounts as well. It’s a win for them as it shows their audience that others love writing about them, and a win for you because brands especially tend to have large audiences.

6. Publish on a site that is social-sharing friendly.

The last major key for having a socially viral post is to simply publish it on a site that is social share friendly. If that is your site, you must add social sharing buttons to your blog template, either through aWordPress plugin, add-on like Add This, or inserting the individual buttons into your blog’s template files.
If you’re not posting your content on your own site, be sure that your target site has social sharing buttons. I publish on a wide range of sites, and the social sharing of those posts can be almost directly linked to the site’s chosen social sharing buttons. Posts I do on sites that only have Twitter andFacebook buttons only get tweets and likes, posts I do on sites with the StumbleUpon button usually get stumbled, and posts on sites with no sharing buttons usually get minimal social shares (but those also tend to get a lot of comments, so there is a trade off).

7. Format your post beautifully.

Last, but not least, is the overall visual presentation of your blog post. If your post is just one big glob of text with no headers, it loses the scanability that readers (and especially social-sharers) love. If it’s on a site that is covered in ads (think the large, ugly Adsense ads below post headers), then people might not even make it to your content.
Just like people aren’t likely to share an ugly photograph (unless it’s a post about the top 10 ugliest animals in the world), they are just as unlikely to share an ugly post. Even if the site isn’t fancy, a clean layout that puts the emphasis on the content (where emphasis belongs) will help in ensuring more social shares for that content.

Why Google Might Put 3D Space Sensors on Tablets

You Will Get The Answer :

The real potential for Project Tango lies in devices that are much smaller, or much larger


Google

“Project Tango” is reportedly headed to tablets, as Google tries to sell developers on the idea of 3D tracking.
First revealed in February,Project Tango uses cameras, sensors and a special, low-power chip to detect its surroundings in three dimensions. Essentially, it’s a way to help computers see objects the same way we do–with a sense of space.

Although Project Tango originally launched on a prototype smartphone, Google now plans to produce roughly 4,000 prototype tablets and give them to developers, according to the Wall Street Journal‘s unnamed sources. Google is hoping developers will then create unique apps using Project Tango’s “advanced vision capabilities.” The devices could launch before the end of June.
So what’s Project Tango for? That’s the tricky part. Google hasn’t said much about why this technology is necessary, or how it would be commercialized, and there’s a sense that the company is just throwing it out there in hopes of finding some real-world solutions. “While we may believe we know where it may go, history suggests we should be humble in our opinions,” Google’s Project Tango website says.
Still, Google has offered a few possibilities: It could help people with vision impairments get around and avoid obstacles, and could highlight the exact item you’re looking at in a store. And already, a firm called Smart Picture Technologies aims to launch a suite of apps for professionals. For instance, an insurance company might use Project Tango to analyze crash scenes with a single picture, instead of having to stitch together multiple disparate ones.
But as I’ve written before, there’s even greater potential in moving beyond the smartphone to wearable devices. While it’s hard to imagine someone waving a smartphone around to find a can of soup at the grocery store, the same application would work well on Google Glass, with the correct item overlaid in augmented reality. Even the ability to tell how many people are around could be useful for a smartwatch, which should know when to show your notifications and when to keep them hidden.
At the same time, Project Tango may lend itself well to even larger, non-mobile devices. A self-driving car, for instance, would get plenty of use from 3D object tracking, so perhaps it’s no coincidence that Bosch, a major automotive parts supplier, is listed as a Project Tango partner. A smart thermostat like Nest (which is now owned by Google) could tell a crowded room from one with just a couple people in it, and adjust temperatures to keep everyone comfortable.
While it’s fun to think about the possibilities, there’s no indication of when Project Tango might be commercialized, how much it costs to include the technology and whether any large-scale hardware makers are interested. For now, Google’s just trying to prove the use cases for it by giving it to a bunch of developers.
So maybe that’s why tablets are the next step. Though it’s hard to see why you’d need 3D space tracking on a device that mainly lives on your coffee table, tablets tend to be cheaper than smartphones. They could be a more cost-efficient way to seed a developer base, even if they’re the least useful place for the technology to be

10 Reasons Why Cats Are Better Than Dogs

If you happen to tell a cat lover that a dog makes a better pet, then be prepared for a heated debate. While it’s true that most pet lovers think that this is still an open question, there are several indisputable scientific facts that clearly show that cats have the edge. For instance, according to a recent research, the number of people who own pet cats in the United States is somewhat higher compared to the number of those with dogs as pets. Also, cats are currently the most popular pet in the entire world. In fact, it’s pretty fascinating to point out that good number of die-hard dog lovers have inched towards the light of the feline side. Basically, this means that you will stand a better chance of winning the argument that cats are indeed the most preferred furred companion, but if you base it on the following 10 reasons why cats are better than dogs. 

Reasons Why Cats Are Better Than Dogs                              

1. Cats treat your guests politely: They won’t maul your guests


It is quite evident that the moment your guest steps through the door, a dog will start barking and pawing at him/her. As a matter of fact, your visitor’s clothes might become covered with dog hair and muddy paw prints that might make him/her feel offended. Fortunately, having a cat as your pet helps ensure that your guests will be treated more politely considering the fact cats often take time to observe new arrivals from afar before acknowledging them with a tail twitch and a cautious once-over.

2. Cats have immaculate hygiene: They are not filthy and smelly like dogs


There is nothing that can scare away your guests as well as your friends than a filthy and smelly dog. Unlike dogs that have a behavior of rolling around in piles of dirt and garbage, cats spend most of their time self-grooming. Ideally, they are fastidious self-groomers, and take care to be clean and odor-free at all times. Additionally, with daily shampooing and brushing, your pet cat can shed somewhat little fur. Essentially, this is one of the key reasons why most women believe that cats are better than dogs.

3. Silence is golden

A cat can save its precious meows to situations when it requires your attention. For instance, if a cat is feeling hungry or rather uncomfortable, it will tend to meow, but not loudly as a dog’s bark. However, this is not the case with a dog since it can bark hysterically at nearly everything or anyone causing distress to both your family and neighbors. With a pet cat, your neighbor will never call you in the middle of the night to complain that your cat is meowing loudly.

4. Cats do not need to be walked or exercised


A dog will tend to be more aggressive if it doesn’t get enough exercise, and to make it worse, it will try to resist any form of exercise like walking, especially if it’s not well trained. Nonetheless, cats can walk themselves, and hence you don’t have to drag your pet around the park when you have better things to do. Dogs must be walked or exercised several times in a day, no matter if it’s blazing hot, snowing, raining or sleeting.

5. A cats is a natural insect repellent


Cats are masters of extermination, particular when it comes to repelling insect or any other winged living things, and will tend to climb walls to dislodge them from their hiding places. It is quite fascinating to note that even lazy fly sneaking in via a screen door has limited chance of survival when you have a cat around your home. Dogs hardly earn their keep because they fail in keeping pests like insects and mice at bay.

6. Food costs: It costs less to feed a cat than a dog


Actually, the cost of pet food is one of the most important considerations that homeowners make nowadays when selecting a pet, especially if it entails a choice between a cat and a dog. Dogs must be fed on high-quality dog food and healthy dog treats, but cats only require a few cans of premium cat food that can last for several days. Basically, the cost of feeding a dog is usually very high depending on the size and energy level of your dog.

7. Cats are more independent than dogs


It is usually quite difficult for most homeowners to leave a dog alone at home without someone to keep an eye on it. This can be attributed to the fact that the dog’s aggressiveness might make it feel restless, and can even cause unnecessary damage to you property as a consequence of separation anxiety. Cats need less care, and thus you can leave them at home for long periods of time without having to worry about any damage to your property.

8. Cats make the best pets if you live in an apartment


Whether you live in a small or big apartment, cats need less space for their supplies, and it is intriguing to mention that you can even get along quite well with up to 3 cats in a small apartment. In fact, many landlords prefer tenants with cats than those with dogs. This can be attributed to the fact that less damage repair will be needed if you move out because of scratched walls and doors, stained carpet, and the need for a completes painting.

9. Cats enjoy bringing gifts to their loved ones


Cats are hunters at heart, and they are simply miniature versions of lions, cheetahs and tigers. As much as it’s true that a cat cant down a wildebeest, it can settle to smaller prey like mole, bird or unidentified critter part. The most interesting thing with a cat’s hunting is that it can bring their hunt to you as proof of its devotion to you. A dog can hunt a whole day, but it will present you with a loud bark.

10. Kittens are cuter than pups

It is pretty remarkable that both puppies and kittens are adorable, but the introduction of the “cute factor” puts more weight onto the latter. Actually, this explains why women most women prefer buying puppies for their children as gifts.
I personally love equally dogs and cats, as well as other pets! But I understand that sometimes cats are better than dogs. What do you think? Are there any other reasons cats are better than dogs? Please share your thoughts in the comments section!

A New Solution That Stops Snoring and Lets You Sleep

                                  

If you’re like most Americans you probably don’t get eight hours sleep each night.
But, if you also constantly feel exhausted, experience headaches for no obvious reason or have high blood pressure, you could have a more serious problem.
That’s because these can all be the result of snoring—which is, in turn, the most common symptom of a potentially serious health problem—obstructive sleep apnea (OSA).
While most people think of snoring as a minor annoyance, research shows it can be hazardous to your health.  That’s because for over 18 million Americans it’s related to obstructive sleep apnea (OSA). People who suffer from OSA repeatedly and unknowingly stop breathing during the night due to a complete or partial obstruction of their airway.  It occurs when the jaw, throat, and tongue muscles relax, blocking the airway used to breathe.  The resulting lack of oxygen can last for a minute or longer, and occur hundreds of times each night.  

Thankfully, most people wake when a complete or partial obstruction occurs, but it can leave you feeling completely exhausted.  OSA has also been linked to a host of health problems including:
  • Acid reflux
  • Frequent nighttime urination
  • Memory loss
  • Stroke
  • Depression
  • Diabetes
  • Heart attack
People over 35 are at higher risk.
OSA can be expensive to diagnosis and treat, and is not always covered by insurance.  A sleep clinic will require an overnight visit (up to $5,000).  Doctors then analyze the data and prescribe one of several treatments.  These may require you to wear uncomfortable CPAP devices that force air through your nose and mouth while you sleep to keep your airways open, and may even include painful surgery.
Fortunately, there is now a comfortable, far less costly and invasive treatment option available.  A recent case study published by Eastern Virginia Medical School's Division of Sleep Medicine in the Journal of Clinical Sleep Medicine concludes that wearing a simple chinstrap while you sleep can be an effective treatment for OSA.
The chin strap, which is now available from a company called MySnoringSolution, works by supporting the lower jaw and tongue, preventing obstruction of the airway.  It’s made from a high-tech, lightweight, and super-comfortable material.  Thousands of people have used the MySnoringSolution chinstrap to help relieve their snoring symptoms, and they report better sleeping, and better health overall because of it.

Self-healing plastics that will repair your car


New York: A scratch on your car need no longer cause you distress - it will soon “heal” itself. 

Researchers have developed a plastic that “heals” on its own by restoring the initial molecular structure after any damage. 

The novel polymer network self-heals within a few minutes at relatively low temperatures, the researchers have contended. 

“Our method does not need any catalyst, no additive is required,” said professor Christopher Barner-Kowollik of the Karlsruhe Institute of Technology (KIT) in the US. 

Barner-Kowollik’s researchers used the possibility of cross-linking functionalised fibres or small molecules by a reversible chemical reaction for the production of self-healing materials. The team took about four years to develop the novel polymer network. 

These so-called switchable networks can be decomposed into their initial constituents and re-assembled again after the damage, the researchers say in an article on their findings published in the journal Advanced Materials.



At comparably low temperatures from 50°C to 120°C, the network exhibits excellent healing properties within a few minutes, according to the study. 

Using the healing cycle developed by them, the KIT researchers have found a large number of intermolecular compounds that close again within a very short term during cooling. 

Mechanical tests, such as tensile and viscosity tests, confirmed that the original properties of the material can be restored completely.

“We succeeded in demonstrating that test specimens after first healing were bound even more strongly than before,” Barner-Kowollik was quoted as saying in the article.

Global warming is not due to natural factors

Expert Says ..



Washington: An analysis of temperature data since 1500 rules out the possibility that global warming in the industrial era is just a natural fluctuation in the earth's climate. 

The study, by McGill University physics professor Shaun Lovejoy, represents a new approach to the question of whether global warming in the industrial era has been caused largely by man-made emissions from the burning of fossil fuels.


Rather than using complex computer models to estimate the effects of greenhouse-gas emissions, Lovejoy examines historical data to assess the competing hypothesis: that warming over the past century is due to natural long-term variations in temperature. 

"This study will be a blow to any remaining climate-change deniers," Lovejoy said. 

"Their two most convincing arguments - that the warming is natural in origin, and that the computer models are wrong - are either directly contradicted by this analysis, or simply do not apply to it," he said.

Lovejoy's study applies statistical methodology to determine the probability that global warming since 1880 is due to natural variability. 

His conclusion: the natural-warming hypothesis may be ruled out "with confidence levels great than 99 percent, and most likely greater than 99.9 percent." 

To assess the natural variability before much human interference, the new study uses "multi-proxy climate reconstructions" developed by scientists in recent years to estimate historical temperatures, as well as fluctuation-analysis techniques from nonlinear geophysics. 

The climate reconstructions take into account a variety of gauges found in nature, such as tree rings, ice cores, and lake sediments. And the fluctuation-analysis techniques make it possible to understand the temperature variations over wide ranges of time scales. 

For the industrial era, Lovejoy's analysis uses carbon-dioxide from the burning of fossil fuels as a proxy for all man-made climate influences - a simplification justified by the tight relationship between global economic activity and the emission of greenhouse gases and particulate pollution, he said. 

"This allows the new approach to implicitly include the cooling effects of particulate pollution that are still poorly quantified in computer models," he added.

NASA 'flying saucer' for Mars to land in Hawaii

It comes in peace <i>(Image: NASA)</i>

In June, while beachgoers in Hawaii sit blissfully unaware, a flying saucer will descend over the island of Kauai. This is not a trailer for an alien invasion movie – NASA is gearing up to conduct the first test flight of a disc-shaped spacecraft designed to safely land heavy loads and one day people on the surface of Mars.
The Low Density Supersonic Decelerator (LDSD) will be lofted into the stratosphere from the US Navy's Pacific Missile Range Facility on Kauai. The inflatable technology is intended to help slow down vehicles after they enter the thin Martian atmosphere at supersonic speeds.
"It may seem obvious, but the difference between landing and crashing is stopping," says Allen Chen at NASA's Jet Propulsion Laboratory in Pasadena, California, who oversaw the successful landing of the one-tonne Curiosity rover in 2012. "We really only have two options for stopping at Mars: rockets and aerodynamic drag."

Inflatable spacecraft

Until recently, NASA had used parachutes and airbags for most robotic landings on Mars, starting with the Viking mission in 1976. But the heavier the load, the harder it is to come in softly. For the car-sized Curiosity, NASA invented an ambitious system called the sky crane, which combined parachutes with landing gear powered by retro-rockets that could lower the rover to the surface on tethers.
However, Curiosity pushed the weight limits of that technology, and future human missions could require 40 to 100 metric tonnes per mission. Such weight can't be adequately slowed by parachutes in the Martian air, which is just 1 per cent as dense as Earth's. Unfortunately, rocket-powered landings are out of the question, too, as the atmosphere is still just thick enough to buffet incoming spacecraft with more turbulence than thrusters can accommodate.
The LDSD design solves this quandary using a balloon-like decelerator and a giant parachute twice the size of Curiosity's. The decelerator would attach to the outer rim of a capsule-like entry vehicle. When the capsule is travelling at about Mach 3.5, the device would rapidly inflate like a Hawaiian pufferfish to increase surface area. The added air resistance would slow the capsule down to Mach 2, at which point the 33.5-metre parachute could safely deploy.

Bridge to Mars

To simulate Mars's thin atmosphere on Earth, the team in Hawaii will first lift a test vehicle fitted with the LDSD system to about 37 kilometres above the Pacific Ocean using a high-altitude balloon. The craft will detach and fire a small rocket to reach a height of 55 kilometres, about halfway to the edge of space. As it falls back to Earth, the system will inflate and moments later the parachute will fire. The saucer should gently splash down in open water.
NASA has three more test flights in Hawaii planned for the LDSD, and mission managers will review the results before deciding on next steps. In addition to landing human missions on Mars, the system could help robotic craft safely land in Martian mountains or highlands. These areas have even less air available for slowing down a spacecraft via drag and so have been inaccessible with current technology.
"Personally, I think it's a game-changer. You could take a mass to the surface equal to something like 1 to 10 Curiosities," says Robert Braun at the Georgia Institute of Technology in Atlanta. "Think about it like a bridge for humans to Mars. This is the next step in a sequence of technologies that would need to be developed."

Digitising cave art will prevent it being lost forever

Trotting off to a virtual future <i>(Image: The Scape Trust)</i>

Virtual records of fragile archaeological sites will preserve them for future generations when it's not possible to defend them from the elements
A RESCUE mission is underway on the Scottish coast north of Edinburgh. Jonathan's Cave, with its rare trove of 1500-year-old rock art, risks being flooded by the sea or buried in a landslide. But rather than fight the elements researchers have opted to save the cave by putting the whole thing on the internet.
A team led by Joanna Hambly, an archaeologist at the University of St Andrews, UK, is using a series of laser and visual scanning techniques to recreate a virtual cave in minute detail.
Starting last year, the team brought in a low-flying drone to shoot aerial footage of the outside of the cave and the surrounding land. Lasers then scanned the cave, both inside and out, to build a 3D model of the site on a millimetre-scale.
The team also scanned the carvings several times using a variety of techniques. In one, a camera snapped images of the walls as they were lit from many different angles. And another approach, called structured light scanning, projected different patterns onto the walls and then read distortions in the patterns caused by the rock surface. This method provides detail down to the level of 100 micrometres – fine enough resolution to examine each individual hammer blow that made up the carvings.
"We're throwing everything at it. There is a danger that we may lose these caves," says team member Tom Dawson of the non-profit trust Scottish Coastal Archaeology and the Problem of Erosion.
An online walk-through of Jonathan's Cave will go live later this month. As well as clicking to move through the cave, you will be able to use the mouse cursor like a torch to illuminate more than 30 different carvings left by the Picts, who lived in Scotland during the Iron Age. These include images of men and animals, Christian symbols and the earliest known depiction of a Scottish boat. If all goes well, the team hopes to recreate the process for other nearby caves that are also in danger of disappearing.
"One of the objectives is to see which technique is most effective at recording heritage like this," says Hambly.
The project is not the first to create a virtual record of fragile archaeological sites.
"This scarce resource is being lost forever," says Frank Weaver, a documentary filmmaker who has been using Microsoft's Kinect depth-sensing cameras to record rock art in Paraguay. "What better way to save it for future studies and appreciation than online?"
Katherine Tsiang, an art historian at the University of Chicago, has used similar methods to digitally record historic caves in China. But she cautions that even high-tech archives are vulnerable to becoming outdated, or simply forgotten about. "All of this digital stuff isn't permanent unless it's carefully maintained," she says.
