  • 10 Human Evolutional Ancestors

    Humans (Homo sapiens) have a highly developed brain, capable of abstract reasoning, language, introspection, and problem solving. This mental capability, combined with an erect body carriage that frees the hands for manipulating objects, has allowed humans to make far greater use of tools than any other species. Human evolution encompasses the development of the genus Homo, but usually involves studying other hominids and hominines as well because evolution of humans started as far as 45 millions years ago and included hundreds of genera and divergence and convergences, here we shall look upon the 10 famous and more important human ancestors in chronological order.

     

    10. More than 7 million to 45 million years old

    Eosimias sinensis

    Eosimias sinensis was first discovered in China. The species is believed to have lived 45 million years before present. E. sinensis was tiny, as small as the smallest monkey and could fit in the palm of a human’s hand.

    Then comes the Aegyptopithecus zeuxis in Egypt, 30 millions years ago with a small brain size of 14.63 cm3. Then came the fruit eating Proconsul africanus 18 million years ago. Sivapithecus an arboreal specie discovered in Pakistan is a 12.5 million year old was a fruit eating ancestor of modern primates. Oreopithecus bambolii and Lufengpithecus lufengensis are 8 million year old prehistoric primates found in Italy and China respectively. An evolutional link as old as this is hard to establish directly except the Sivapithecus in Pakistan that are most close to modern primates.

     

    9. Sahelanthropus Tchadensis

    Sahelanthropus tchadensis is an extinct old hominid species which is believed to be almost 7 million years old. Whether it can be regarded as part of the Hominina tree is unclear; there are arguments both supporting and rejecting it. Another complication in its classification is that it is older than the human-chimpanzee divergence (estimated to 6.3 to 5.4 million years ago) seen in genetic data,and that there are few if any specimens other than the partial cranium.

    The braincase, being only 320 cm³ to 380 cm³ in volume is similar to that of extant chimpanzees and is notably less than the approximate human volume of 1350 cm³. The teeth, brow ridges, and facial structure differ markedly from those found in Homo sapiens. Cranial features show a flatter face and u-shaped teeth piece.

     

    8. Orrorin Tugenensis

    Orrorin tugenensis is considered to be the second-oldest known hominin ancestor that is possibly related to modern humans. The strata in which the fossils were found were estimated to date between 6.2 and 5.6 million years ago. The fossils found so far come from at least five individuals.

    There are proofs that Orrorin walked upright and bipedally; data was suggestive of tree-climbing skills. The small teeth size suggest that Orrorin ate mostly fruit and vegetables, with occasional meat. Orrorin was about the size of a modern chimpanzee.

     

    7. Australopithecus Afarensis

    Australopithecus afarensis is an extinct hominin which lived between 3.7 and 2.9 million years ago. A. afarensis was slenderly built, It is thought that A. afarensis was ancestral to both the genus Australopithecus and the genus Homo, which includes the modern human species, the Homo sapiens. The most famous fossil is the partial skeleton named Lucy (3.2 million years old) by Donald Johanson and colleagues.

    Australopithecus afarensis fossils have only been discovered within northern Africa. A. afarensis was almost exclusively bipedal. The curvature of the finger and toe bones is most likely reflective of their ability to efficiently grasp branches and climb. A. afarensis also has a relatively small brain size (~380–430 cm³) and a projecting face.

     

    6. Australopithecus Africanus

    Australopithecus africanus was an early hominid, who lived between 2–3 million years ago.

    A. africanus was slenderly built, or gracile, and was thought to have been a direct ancestor of modern humans. Fossil remains indicate that A. africanus was significantly more like modern humans than A. afarensis, with a more human-like cranium permitting a larger brain and more humanoid facial features. A. africanus has been found at only four sites in southern Africa.

    The Light Touch from Light Blue Optics is a marvel — it can beam a virtual computer on to any flat surface, allowing users to tap away as though on a proper keyboard. It’s not commercially available — the Cambridge-based company is hoping to license the technology to other manufacturers — but if it does go on sale, it could herald a shift in the way we interact with the world around us.

     

    2. Apple Tablet

    When Apple introduced the iPhone, it shook up the cell phone business. Now, with the looming launch of a tablet-style computer, that definately means a new era for gadgetiers. It’s a tablet computer that can surf the Web and play music and videos. Apple’s tablet will use Verizon’s wireless data network to connect to the Internet when users are out of range of a Wi-Fi hotspot.  Just look at the image and for sure, you can’t help but drool over the possibility of having one in the near future.

     

    3. Plastic Logic Que E-Reader

    This will be the e-reader to own in 2010. The flat body reaches almost sci-fi-like thinness, and because the 11.6-inch screen has touch capability, the bezel is entirely free of buttons except for “home,” just like an iPhone or iPod Touch. Plastic Logic has also forged partnerships with over 300 newspapers and magazines to have their content specially formatted for the device to preserve the print-like formatting – an important aspect of those publications that is largely lost on other e-readers.

     

    4. Microsoft Courier

    Want to keep track of your appointments, to-do lists, and contacts in a techie way? Then, this is the gadget for you. Microsoft announced the development of its Courier Tablet last week and leaked videos show how the new interface will function.The heart for the Microsoft Courier  seems to be the infinite journal which is only bound by the storage constraints of the device. The Microsoft Courier functions mainly by keeping track of your appointments, to-do lists, etc. It is also made to be flexible so you can create original sketches and drawings using MS Paint. Plus, with this device, you can snap photos, browse the web, take notes, and clip text and images from Internet pages. And guess what? It functions as an e-reader too, just like these ebook reader devices at Amazon.

     

    5. Toshiba Cell TVs


    Image Source
    The Cell Processor-powered 3D HDTV from Toshiba has just about every feature you could ever imagine, and on top of that, the picture quality (colors, black levels, clarity) is extremely impressive. Arguably though, the most talked about feature of the Cell TV was the real-time 2D-to-3D conversion that the set is capable of doing, regardless of the input content (home video, pictures, movies, video games). We think that the presence of the 2D-to-3D conversion feature could be a major factor when it comes time for the consumer to make the jump into 3D, regardless of how good it looks, because it will effectively make all of their content 3D, and that translates to more perceived value. Of course, Toshiba is not alone in the conversion market. Competitors like Samsung, JVC and others were demoing their own 2D-to-3D conversion material but it wasn’t clear how the effect was being achieved. All in all, the Cell TV is a promising entry from Toshiba. We found it hard to find fault with any other aspect of the unit. This one could be a real winner for Toshiba when it’s paired with their Blu-ray 3D player, the BDX-3000. Additional glasses will be available separately but again, the price is not yet known. Collecting 3D glasses for multi-person viewing looks to be shaping up to a similar financial exercise as collecting controllers for video game consoles.

    6. Zyxio Sensawaft

    Have you ever wanted to control the cursor on your computer using only your breath? No? That’s a shame, because that’s exactly what the Sensawaft does. By blowing in to a special ‘microphone’, you can control the speed and direction of the cursor across your computer screen. Zyxio, the company behind the technology, says it could be very useful for disabled computer users, and also envisage it being applied to other scenarios, such as controlling a mobile phone, being used as a “third hand” when playing an action-packed video game, or even operating in-car sat-nav. We’ll see the first Sensawaft devices go on sale later this year, costing around £60.

     

    7. 4g iPhone

    KT, a company partnered with Apple to sell iPhones in South Korea, revealed its plans to begin selling the 4G iPhone as early as April. We can obviously expect the phone to include new radio hardware for connecting to 4G networks, and KT’s reports indicate the phone will feature a new dual-core CPU for a speed boost. The screen is to be switched from a standard LCD to an OLED model, which could mean a brighter picture and reduced power consumption. There could also be a front-mounted camera for video chat and a battery that’s finally removable by the end-user.

     

    8. Lenovo IdeaPad U1

    Hybrid technology has come to computers but it doesn’t mean your laptop will now run on hydrogen.

    Lenovo’s innovative ‘hybrid’ device is actually two gadgets in one — a notebook that looks much like a conventional laptop computer, except that it has a detachable screen, which doubles as its own separate tablet computer. Each part has its own processor and operating system, giving the one computer multi-functionality. They also synchronize to work as one machine with the base a hub and docking station and the tablet the mobile device. 3G wireless is built in. The U1 components each support more than five hours of 3G web browsing, 60 hours of 3G standby. It also has a video camera. The IdeaPad U1’s laptop and tablet modes each support more than five hours of 3G Web browsing and 60 hours of 3G standby. In addition, the U1 comes with integrated video camera and two stereo speakers with integrated microphone with echo cancellation make this the ideal PC for users who need flexibility but do not want to compromise features or functionality. The entire duo-purpose machine weighs in a 3.8 pounds and in the traditional notebook form  it has a 11.6 inch HD LED screen, with Windows 7.

    Augmented reality — in which real-world images are overlaid with useful data, information or rich content — is set to be one of the big success stories of 2010. Some experts even expect the technology to filter down to the world of video games, and that’s what Parrot’s drone was designed to showcase. The helicopter-style drone, powered by four small blades, floats lazily through the air. On board are two mini video cameras, which send images back to an iPhone, which is running a special app that transforms the device in to a remote control for the chopper, as well as a video game. By tilting the iPhone, players can change the direction of the quadricopter, while images beamed back from the chopper are overlaid with virtual pictures of monsters or aircraft zooming across the screen.

  • 11 Innovative and Interesting Ways to Generate Power

    In today’s era, energy demands are exponentially high and energy resources are depleting rapidly. It’s time to come up with some innovative and brilliant ideas to generate environment friendly and low cost energy without utilizing the already becoming extinct energy resources. The following list is a compilation of some excellent ways to generate power. The ways follow the law of conservation of energy.

     

    11. By Playing Golf or Cricket

    Golf Play Golf to Charge Your iphone A golf, cricket, tennis or baseball player uses a lot of his or her energy in swinging the club, bat, racket or base back and forth. This kinetic energy generated by the player can be stored for later use. The stored energy can charge the cell phone, laptops and other gadgets later. The device is initially designed for golf players. It includes the hand grip only and not the actual club. This gadget is envisioned and designed by Mac Funamizu.

     

    10. Car Washing

    Car Washing Turbine Inside Hoose Pipe Source The innovative device designed by Vandenbussche, POWA Water Generator, is just a small turbine that is placed in between the hosepipe used to wash to cars or water the lawn. As the water rushes through the pipe, the blades of the small turbine turn and generate electricity.This company envisioned the system to charge the batteries of the electric cars but this electricity can be used for other purposes also.

     

    9. Cycling

    Cycling to generate electricity Cycling to Generate Electricity The Crown Plaza Hotel in Copenhagen, Denmark, came forward with an exciting and innovative way to generate power. The system includes the guests staying at the hotel and cycles. They offer a free meal to any guest who produces electricity for the hotel on an exercise bike attached to a generator. Guests will have to produce at least 10 watt hours of electricity which is around 15 minutes of cycling to get a meal vouchers worth $36 (26 euros). This system gives health benefits as a by product to the generated electricity. The energy produced can generate energy to run a laptop for approximately 30 minutes. The idea is easy to implement and can be implemented by anyone on an individual’s level.

     

    8. Exhaust of a Vehicle

    Exhaust of a car Exhaust of a Car The unconsumed fuel of the vehicle comes out from the exhaust in the form of heat. This heat can be harnessed to generate electricity. Thermoelectric generators convert heat into electrical energy by making use of a temperature gradient. The greater the temperature difference, the more current can be produced. Researchers at the Fraunhofer Institute for Physical Measurement Techniques IPM are working on a project to capture and utilize the residual heat in automobiles. “The temperatures in the exhaust pipe can reach 700 degrees Celsius or more,” says Dr. Harald Böttner, head of the Thermoelectric Systems department. “The temperature difference between the exhaust pipe and a pipe carrying engine cooling fluid can thus be several hundred degrees Celsius.” This temperature difference is used to generate current. This electricity can cover a fairly good proportion of car’s power requirements.

     

    7. Solar Panels on Rooftop and in Backyard

    Home Solar Panel Solar Panels on Rooftop An interesting way to generate electricity is by covering the roof of the house with a layer of solar panels. These panels serve dual purpose as they in addition to generating electricity provide insulation and lower the temperature of the house. The panels can also be placed in the backyard.

     

    6. Dancing on Floor of a Club

    Disco-Club Dancing Club Dancing Till date we had been of the view that clubs are the maximum consumers of electricity as the music and the lighting systems consume a lot of power on daily basis. Now the clubs are an excellent place to generate power too. The idea was implemented by a club, Bar Surya, in London, that re-outfitted its floor with springs. The springs when compressed by dancers, produce electrical current. This current is stored in batteries and consumed to run the devices in the club. According to the club’s owner, Andrew Charalambous, the dance floor can now power 60 percent of the club’s energy needs.

  • 10 Most Useless Inventions

    I was surfing the internet when I saw this crazy useless invention that hit the limelight a couple of weeks ago. Just so you know, that thing is discussed in this list and is actually at the top spot. I figured that if there are brains that can actually put this sort of a thing into production then there might be other geniuses out there with absolutely amazing inventions. So I researched and here I am with the list on ten of the most useless things you can actually buy. Enjoy the read!

     

    10. CAT WIGS


    I happen to be a cat person and this particular invention actually annoys the hell out of me. Cats are lovely creatures; they are beautiful, pretty and insanely cute. Why on earth would I want my cat dressed up in a wig? That’s exactly what a cat needs because they are so jealous of human hair. They have their own hair to worry about sir!

     

    9. THE DOG SACK


    I am sure most of our readers love dogs. I love them too but that’s not the point. You take a nice family trip and you bring your dog along. Now, if you care enough to take the dog along with you, I am sure it will not bother you if the dog actually sits inside the car right? This particular invention is all about installing a sack right outside the door of your car so your dog can have a seat of his own. Pretty genius, at least until you’re in a bumper to bumper traffic. Yeah, that ought to be fun.

     

    8. PHONE FINGERS


    We are living in a smart age where smart phones and other smart products are the thing. I am sure most of you own a smartphone, and probably the one with a touch screen. If you keep using the phone for a long time, you must have noticed that the screen gets a little smudgy with body oils and finger prints. Well, fear not because now you can wear these condom-like and so totally gay finger gloves to protect your screen. Your screen will never be smudgy again. Of course you can imagine how much of a hassle it will be to actually wear these and then take them off in emergencies. Hats off!

     

    7. SUBWAY CHINREST


    The last I heard, man was a social animal. I was unaware that that has changed to just ‘animal’. Are you aware that donkeys can actually sleep standing up? Well, don’t be jealous because on the subway, you can do the same thing and it is not limited to subways. You can very well have this pole in your house, because when is bed ever a comfortable place to sleep. Most of the times, people don’t get a seat on the subway so they have to stand, and the neck starts hurting if you keep standing for a long time, therefore, Subway Chinrest was born.

     

    6. THE PIZZA FORK


    You know how difficult it is to use both your hands while eating a pizza. You know, you hold a fork in one hand and a knife in the other one. Wouldn’t it be amazing if you could do everything with just one hand while the other hand rests? I think that’s what the inventor of this particular fork had in his mind. I mean, why, WHY would you install a pizza-cutter right on the fork? We can use two hands, and even if we are unfortunate enough to not use the other hand, we can manage. Thanks for your creativity, but no thanks.
