But Japan's boldest plan to date is the Space Solar Power System (SSPS), in which arrays of photovoltaic dishes several square kilometres (square miles) in size would hover in geostationary orbit outside the Earth's atmosphere
A breakthrough mix of stem cell and gene therapy halted a lethal brain -wasting illness in two young boys, and could prove effective against other genetic disorders, researchers reported Thursday.
NASA scientists studying the origin of life have reproduced uracil, a key component of our hereditary material, in the laboratory. They discovered that an ice sample containing pyrimidine exposed to ultraviolet radiation under space-like conditions p
Supervolcanoes and cosmic impacts get all the terrible glory for causing mass extinctions, but a new theory suggests lowly algae may be the killer behind the world's great species annihilations. Today, just about anywhere there is water, there
A new study involving an international team of scientists and reported in the journal Geophysical Research Letters finds the processes creating the rift are nearly identical to what goes on at the bottom of oceans, further indication a sea is in th
We believe we can use microwave heating to cause the water ice in a lunar permafrost layer to sublimate – that is, turn into water vapor. The water vapor can be collected and then condensed into liquid water." "Best of all, microwave extraction ca
NASA's Spitzer Space Telescope has discovered an enormous and previously unknown infrared ring around Saturn. "This is one supersized ring," says Anne Verbiscer, an astronomer at the University of Virginia, Charlottesville. "If you could see t
A big question mark was the existence of a two thousand year or more Bronze Age optimum that ended with the Hekla event in 1159BCE. We ran down a lot of factors and in fairness none appeared up to the task of explaining that particular optimum.
September 24, 2009: Meteorites recently striking Mars have exposed deposits of frozen water not far below the Martian surface. Pictures of the impact sites taken by NASA's Mars Reconnaissance Orbiter show that frozen water may be available to explore
Challenging conventional wisdom, new research finds that the number of sunspots provides an incomplete measure of changes in the sun's impact on Earth over the course of the 11-year solar cycle. The study, led by scientists at the National Center for
I return today to the subject of the class of reptiles properly described as dawn age reptiles. My researches have stumbled into more telling reports and the phenomenon is sorting itself out. We can begin to characterize the phenomena a lot better.
This marks a new beginning for Hubble," said Ed Weiler, associate administrator for NASA's Science Mission Directorate. "The telescope was given an extreme makeover and now is significantly more powerful than ever, well-equipped to last into the next decade."
No one is certain yet just how frequently freak waves form; accurate numbers are extremely difficult to collect given the waves' rare and transient nature. With more sophisticated monitoring and modeling—and as first-hand accounts are taken more seriously—the waves' prevalence appears to be rising.
The NuVinci CVP represents a quantum leap forward over other CVTs as well as conventional mechanical transmissions. These advantages include: Higher torque density Smaller size/weight Easily scalable Simpler More adaptable and versatile Improved overall performance Easy to package (less space required) Lower manufacturing and maintenance costs
In the latest research, the team replaced the Mylar with pure carbon. In this setup, the growing nanotubes literally raise the roof, lifting up the iron and aluminum oxide from which they’re sprouting while the other ends stay firmly attached to the carbon. As the bundle of tubes grows higher, the catalyst becomes like a kite, flying in the hydrogen and acetylene breeze that flows through the production chamber.
It is possible though that we evolved into organisms that have out stripped our ability to produce stem cells. In short we simply have metabolisms that operate far to fast to be able to replace all the damage as needed unlike the above mentioned reptiles. Thus creating a mechanism that takes up the slack may be a way to bring the human aging cycle under control and restore the possibility of biological immortality to humanity.
"A Thermal Ground Plane is basically a materials system,” Nadler explained. “The most thermally conductive natural material, pure diamond, has a conductivity of about 2,000 watts per meter Kelvin. We’re aiming for 20,000, and to do that we have to look at the problem from a materials systems standpoint.”
We can also agree that this comet carries water in particular. Unfortunately, this has leaned heavily on the thinking of theorists and it has been supposed that as the comet approaches the sun that the increased warmth helped create a cloud. I do not think it has much to do with warming at all. Much more likely, the dust mass progressively charges up because of increased radiation from the sun. This induces charge accepting particles to separate, and of course the comet is an accumulation of dust. I suspect that the main charge accepting particle is carbon soot. Thus a comet is a mass of fine condrite dust, water and ammonia vapor and lots of free carbon soot.
I have already explained why these reptiles can be still extant. They are aquatic and rely on water immersion to control body temperature. That means that they stick to swamps and related rivers. The sea going version may also be around but obviously having no pressing need to spend time on the surface at all. Their present populations are likely at low ebb, but that merely reflects the present paucity of swamps. We are missing most of the Saharan swamps and those of the Outback. Both these would have compared to the Congo. We are also missing the coastal swamps caused by the Northern Ice age that circled the continents.
We discuss and comment on the role agriculture will play in the elimination of the CO2 problem and address methods for terraforming the planet Earth. A model farm template is utilized and is the central methodology. Thursday, July 23, 2009 13000 Year Old Soot Having this story make scientific America is certainly welcome. The theory was first published about four years ago and sank like a stone. I have commented a great deal on its importance providing a radical interpretation that I expect few to accept anytime soon. The comment that the black mat varies in age and has different geological sources is odd. The soot layer is convincingly unique, unless someone is able to show me multiple layers over eons. That argues for a unique causation and additional argues for a critical review of the methods for determining age which we already know is fickle. An island has less capacity to withstand a shock, while a few human enclaves ca

Infants just 6 months old can match the sounds of an angry snarl and a friendly yap to photos of dogs displaying threatening and welcoming body language. The new findings come on the heels of a study from the same Brigham Young University lab showing that infants can detect mood swings in Beethoven’s music
The eclipse is extra-long because of a lucky coincidence, made possible by the elliptical shape of planetary orbits. On July 22nd, Earth happens to be near its farthest point from the sun. A small sun means the Moon can cover it longer. At the same time, the Moon will be near its closest point to Earth. A large Moon covers the sun longer, lengthening the eclipse even more.
No one knows exactly how much Earth's climate will warm due to carbon emissions, but a new study this week suggests scientists' best predictions about global warming might be incorrect. The study, which appears in Nature Geoscience, found that climate models explain only about half of the heating that occurred during a well-documented period of rapid global warming in Earth's ancient past. The study, which was published online today, contains an analysis of published records from a period of rapid climatic warming about 55 million years ago known as the Palaeocene-Eocene thermal maximum, or PETM.
That now brings up another issue. A previous post on the Antarctic ice core, established that every 100,000 years or so we swing by Sirius and get bathed in ultraviolet radiation for a thousand years or so. The effect of this is to essentially melt out a large part of the ice caps and add perhaps another couple of hundred feet of sea level. The temperature will rise several degrees on average and that surplus must migrate north. Far more importantly huge amounts of water will find its way into the atmosphere introducing enough rain to establish tropical conditions almost to the poles themselves. It also means a massive expansion of Amazon tropical rainforest like conditions far to the north. The Mississippi valley, the Sahara, the Outback, the Middle East will all become saturated swamplands fully able to support their own populations of crocodiles.
The head appeared over bushes ten feet tall. It was about the size of a beer keg and was shaped like that of a tapir, as if the snout was used for pulling things or taking hold of them. The eyes were small and dull and set in like those of an alligator. Despite the half dried mud we could see that the neck, which was very snakelike, only thicker in proportion, as rough knotted like an alligator's sides rather than his back.
Therefore, we can make a hesitant conjecture. These critters may still be extant and functioning in the major global swamps. Locating them will also be a daunting challenge and will take a major effort. Occasional eyewitness reports have been futile to date since these animal are simply too large for capture or even killing when encountered. We are simply never heavily enough armed in the first place and having handling equipment to hand is also unlikely. So far, almost no one has been prepared to believe these reports.
My point though is that complex cultural evidence should appear between 60,000 BP to 13,000 BP. Since I also suspect that much of humanity made itself scarce before the Pleistocene nonconformity, it is reasonable that such evidence should show a disconnect between the present era and the previous era. Accordingly, it becomes obvious that the locale with the best chance of providing conforming evidence is Australia, not least because the shift turned it into an arid desert for the most part.
What I have learned to appreciate though is that the locales are huge in their own right and are unpopulated by man for some incredibly good reasons. Like, how do you keep hungry crocodiles away? What is also not understood is that the areal extent compares to France and has maintained a Dawn Age swamp rich ecology since then. Add in the simple fact that these water loving reptiles are active hunters at night to avoid overheating in the sun and we have a challenging hunt on our hands.
The revolution in fishing first came in the 1600s, when boaters began taking their vessels out in pairs to fish with nets. Then, large scale fisheries began to take hold in the 1800s. "The impact of early fisheries was substantial," Holm
