Mysteries of First Human

Why did we grow large brains? There is no question that our large brains have provided humans an extraordinary advantage in the world. Still, the human brain is an incredibly expensive organ, taking up only about 2 percent of the body's mass yet using more than a fifth of the body's energy, and until about 2 million years ago none of our ancestors had a brain larger than an ape's when compared to body size. So what kicked off the push for a larger brains? One possibility is that increased smarts helped our ancestors make better tools. Another is that larger brains helped us interact better with each other. Perhaps radical changes in the environment also demanded that our ancestors deal with a shifting world. Why do humans walk on two legs? Our ancestors evolved an upright posture well before our large brains or stone tools even appeared. The question, then: Why stand and walk on two legs when our ape cousins get by on four limbs? Walking as bipeds might actually use le...

BrightSource solar thermal power plants can be equipped with a two-tank molten salt storage system, as shown on this image. BrightSource Energy today announced molten salt energy storage for its heat-driven solar power plants, touting the advantages over flat solar photovoltaic panels. With the storage, BrightSource solar power plants can deliver electricity to the grid consistently and into the evening hours. That makes the solar power more valuable because utilities pay more for power during peak hours, which continues past nightfall. BrightSource's solar tower technology generates steam from a field of mirrors called heliostats shining onto a tower. The steam is fed into a conventional turbine to generate electricity. After turning the turbine, the steam is condensed into water and fed back to the tower to be heated again. In a plant with solar storage, the steam from the tower is fed into a heat exchanger that raises the temperature of so-called "solar salts" stored...

Tough Times for Ancient Warrior

Battling nomads earned you buckets of trouble around 2,500 B.C., reports an international archeology team. Scars too. But at least you earned yourself a fancy burial. "Intensive excavations in the Near East, which have been carried out for over 100 years, show that this region merits to be called a cradle of civilization," begins the International Journal of Osteoarcheology report led by Jacek Tomczyk of Poland's Cardinal Stefan Wyszynski University. The study team reports on two Bronze Age burials in a tomb from the ancient trade town of Terqa, a Mesopatamian archeological site in modern-day Syria. "The tomb from Terqa consisted of two chambers with stone domes. The smaller chamber contained many luxury grave goods, including jars, plates and pieces of ancient jewellery. The artifacts were placed in an orderly manner, one upon another. Small animal bones and crushed ostrich eggshells indicate that this part was visited by people who left there some offerings. Th...

Tequila mooted as eco-friendly biofuel

We've always been told driving and alcohol don't mix, but there's now a distinct possibility we could all be driving around tanked up on tequila, according to the usually very sober Guardian . Researchers at the University of Oxford have suggested that agave, the hardy plant from which the bitter liquor is distilled, is an ideal source from which to create the petrol substitute ethanol, as it has a far lower environmental and social impact than conventional ethanol-making crops. This comes as no surprise to Crave. We've been aware of tequila's benefits for years, but writing a white paper on the subject the morning after an extensive bout of experimentation has usually taken a back seat to figuring out why our brains feel as if they've been used as a fat person's trampoline. Thankfully, scientists have stayed sober long enough to do the research we couldn't. They've found that, like many biofuel crops, agave-derived ethanol is potentially very eco...

Cloud Computing

The main thrust of early cloud computing discussions--even before that particular term became popular--was fundamentally about economies of scale. For example, in his book "The Big Switch," author Nick Carr writes that: "Once it becomes possible to provide the technology centrally, large-scale utility suppliers arise to displace the private providers." This was an imagined future of computing that reprised a journey taken by power generation technology in which expensive and customized local water turbines or steam engines driving gears and belts largely gave way to motors connected to the electric grid. This early-on discussion wasn't so much about how computing took place--presumably it would be handled efficiently by the mega-service providers offering this new type of utility. Rather it was about the economic model: standardized pay-as-you-go services delivered at massive scale. Worldwide server revenue associated with private clouds is forecast to grow mor...
