his also suggests a long pattern into which we also can fit the cold weather that ended the Roman Empire in the fifth century. The cycle appears to be around 1200 years long. Our minima can then be isolated as 1700AD, 500 AD, 700BCE, 1900BCE, and 3
A giant invisible galaxy is colliding with our Milky Way, astronomers have discovered. It is a vast cloud of hydrogen containing enough matter to make one hundred million suns - but has failed to produce any stars at all. The presence of the dark blo
"The Carbon the World Forgot" identifies the boreal forests of North America as not only the cornerstone habitat for key mammal species, but one of the most significant carbon stores in the world, the equivalent of 26 years of global emissions from
The existence of the giant squid in deep water proves that it is possible for a cold blooded creature to live and absorb sufficient oxygen in the cold water deeps of the ocean. Remember that the surface layer of the ocean is not overly thick at per
Rising water temperatures are kicking up more powerful winds on Lake Superior, with consequences for currents, biological cycles, pollution and more on the world's largest lake and its smaller brethren.
Sometimes you really can believe your eyes. That's what NASA's STEREO (Solar Terrestrial Relations Observatory) spacecraft are telling researchers about a controversial phenomenon on the sun known as the "solar tsunami
And then there are legitimate questions about wind-turbine noise—turbines do create sound after all, from both the gearbox (though this has grown much quieter in newer turbines) and from moving blades. It’s no more harmful than the noise from new hig
Jin Changzhu and colleagues of the Institute of Vertebrate Palaeontology and Palaeoanthropology in Beijing, announced to Chinese media last week that they have uncovered a 110,000-year-old putative Homo sapiens jawbone from a cave in southern China'
Titicaca's waters have dropped 81 centimeters (2.65 feet) since April and flora and fauna are apt to suffer damage if they drop another 30 centimeters (one foot), the statement said. Navy Capt. Jorge Ernesto Espinoza told ATB television that South
What they found was that the bristlecone pines at treeline grow faster when temperatures are warmer-in contrast to the trees lower down the mountain, which grow faster with higher amounts of precipitation and when temperatures are cooler. In other wo
According to mainstream science, the dinosaurs died out about 65 million years ago. According to cryptozoology and certain other branches of periphery science, a few dinosaurs might have survived much longer, or could even be around today. The most f
Based on the measurements, the team estimated that there was about 220 pounds (100 kilograms) of water in the view of their instruments, which took in the area of the impact crater (about 80 feet or 20 meters across) and the ejecta blanket (about 200
Mr. Prouty estimates it will take his company “not 15 to 20 [years], but not 3 to 5 either” to go from the research stage to power generation. TriAlpha is the brainchild of Norman Rostoker, a senior fusion researcher. He had previously coll
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
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.
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.
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.
