Toyota's HiLux Tonka Concept channels your inner child Last year, the Toyota HiLux was the best-selling vehicle in Australia – it was the first time that a non-passenger-car took the title. This year, Toyota celebrates its 80th birthday, plus the classic Tonka toy truck brand turns 70. Toyota Australia has decided to mark those milestones by creating the rock-crawling HiLux Tonka Concept. At the base of the one-off vehicle is a top-of-the-line production HiLux, namely the SR5 double cab 4x4 with a 2.8-litre four-cylinder turbo-diesel engine. That vehicle has been given an extra 150 mm (6 inches) of ground clearance, along with a high-riding axle, heavy-duty suspension and 35-inch tires. Out of Africa I - Wikipedia This article is about early humans. For migrations of modern humans, see Out of Africa II. In palaeoanthropology, Out of Africa I is the first series of hominin expansions into Eurasia, which took place from 1.8 to 0.8 million years ago (Ma). Shortly before in Africa, Homo erectus had descended from the woodland-restricted Homo habilis. H. erectus, diverging from H. habilis, adapted to the open grounds of the savannahs and arid landscapes, and later managed to expand out of East Africa, eventually into Eurasia.

From Earth to orbit using a single-stage rocket New Mexico-based ARCA Space Corporation has announced that it is developing the world's first Single Stage to Orbit (SSTO) launch vehicle that can deliver both a small payload and itself into low Earth orbit, at a cost of about US$1 million per launch. Dubbed the Haas 2CA after the 16th century rocket pioneer Conrad Haas, the new booster uses a linear aerospike engine instead of conventional bell-shaped rocket engines to do away with multiple stages. Getting into space is a very complicated affair. To put a payload, like a satellite, into orbit means shooting it out of the atmosphere at about 18,000 mph (29,000 km/h).

For what they were... we are: The various options for the migration out of Africa I want to call your attention to the latest entry at M. Petraglia and colleagues' blog Ancient Indian Corridors. The main focus of this short entry (with open access links to the relevant papers) is the Jubbah site in what today is the terrible Nafud Desert but what really called my attention the most is this other article: Trailblazers across Arabia, where Petraglia discusses not just his own work on the matter of the migration out of Africa of Homo sapiens but also the recent one by Armitage, who proposed a coastal migration via southern Arabia some 125,000 years ago. This map from that article really synthesizes the various options, even if the matter on when the migration happened (125 Ka ago or more like 90-80 Ka ago) remains open: Sadly the Ice Age sea levels are not reflected, for that reason we cannot appreciate that the Persian Gulf was then above sea level, constituting a fertile riverine and swampland region that surely hosted plenty human settlements.

1991 Nissan 240SX DeathKart Unless you really know your stuff, it’d be hard work to deduct from what donor car this apocalyptic Mad Max style death mobile got its start. Aptly named the DeathKart, it’s the brainchild of drift enthusiast Mike Perez and a wild workshop called Speed Warhouse that turned a ’91 Nissan 240SX into a shredding mayhem machine. Out of the original donor vehicle, outfitted as a drifter, the engine that Mike thought suited his ride the most was a turbocharged 2.5L 1J.

Handprint : Ancestral Lines Hominid Fossil Sitesand Patterns of Hominid DispersalWhen and how new hominid species appeared, and how they affected or displaced already existing species, are questions that many lines of research are helping to answer. Patterns of human migration form a key part of the solution. Recently, with more powerful geological dating methods based on fluctuations in the earth's magnetic field or electron spin resonance, the earliest Homo erectus fossils from China have been dated to 1.9 million years ago. This requires an even earlier date for the emergence of Homo ergaster in Africa, implying humans first evolved about 2.5 million years ago. Bang & Olufsen BeoSound Shape Speakers The ultimate goal for any personal speaker system is to have the sound it produces feel as if it is filling the room rather than coming from one specific area or corner. The BeoSound Shape from Bang & Olufsen more than accomplishes this task – not to mention it looks spectacular while dong so. This modular system from the Danish consumer products company is made up of single hexagonal speakers that function as amplifiers, speakers, and acoustic dampeners. All of this means that users can assemble the speaker system exactly how they like, and then rearrange them as they see fit.

Climate Swings Drove Early Humans Out of Africa (and Back Again) - SAPIENS The textbook narrative of human history tells us that between 70,000 and 60,000 years ago our earliest modern human ancestors traveled out of Africa on a journey that led them to nearby continents. But the factors that drove this mass exodus—as well as when it occurred and whether there was more than one big migration event—have long been points of spirited debate and contention. In a study published today in Nature, researchers report that dramatic climate fluctuations created favorable environmental conditions that triggered periodic waves of human migration out of Africa every 20,000 years or so, beginning just over 100,000 years ago. These findings push back the clock on the earliest known arrivals of humans in Europe by tens of thousands of years and provide important clues about what drew early humans out of Africa and into Eurasia and beyond. In contrast, periods of low temperatures and extreme drought would have made human travel far less likely.

Instantly 3D Print Cities with SketchUp PlaceMaker - SolidSmack - SketchUp has a very interesting extension called “PlaceMaker” to instantly generate 3D models of cities. I don’t often recommend SketchUp for 3D printing purposes, as it is primarily focused on visual 3D, rather than the solid 3D required for proper 3D printing. It’s just too easy to create non-3D printable models in SketchUp and you are best to use other 3D print-specific tools. Nevertheless, SketchUp does offer a very interesting extension I haven’t seen in other environments yet. Their “PlaceMakers” extension has the wonderful ability to automatically generate a 3D model of cities, including buildings, roads, and greenery. Take a look at the image above and imagine building that by yourself, even with an efficient 3D tool.

Migratory Crossings Out of Africa For the human journey to really get into its stride, our species had to leave the warm embrace of mother Africa. Researchers identify the Bab-el-Mandeb Strait on the Red Sea as the most likely departure point. This narrow stretch of water between the Horn of Africa and the Arabian Peninsula offered the shortest route to new continents. The strait would actually have been even less of a stretch than it is today (12 miles), because when Homo sapiens made the crossing some 60,000 to 70,000 years ago, sea levels were 230 feet lower due to the onset of ice age conditions that locked water up in vast polar ice caps.
