The age of these trees and the great likelihood of human transportation makes it an excellent research tool. There are no growth rings to make it simple, but each unique node will have a unique age signature. That means the sampling will be costly, b
If all four nucleotides formed naturally, they would zip together easily to form an RNA molecule with a backbone of alternating sugar and phosphate groups. The bases attached to the sugar constitute a four-letter alphabet in which biological informat
It was in the right location and was certainly big enough and perhaps even small enough. Importantly, there were no other recent geological events that came close to matching it. And a quick check of geological reports indicated an extraordinary yout
The end result was a total of eight collagen peptides and 149 amino acids from four different samples, sequences that held up when multiple validation steps were performed, including comparisons with synthetic peptides using a spectral comparison alg
"The high resolution of TerraSAR-X satellites enables us to observe deformations in the Wilkins Ice Shelf, down to the range of approximately 100 metres," says Dr Humbert, and she goes on to add: "This information enables we glaciologi
So began a US, New Zealand and Australian research project to understand ice core records spanning hundreds of thousands of years, profiling periods of high-methane increase and focusing on the Younger Dryas period. The cause of the large increase in
With the large populations gone, the mammal populations obviously took off and began filling vacated niches as fast as possible including open plains needing large animals. The weakened ability of the large reptiles to rapidly reexpand their populat
As expected THEMIS continues to surprise us as it maps the plasma surrounding the Earth. We have now discovered that huge tornado like plasma funnels shape electrical flow into our ionosphere to produce the Northern Lights. And that pretty well ends
Based on initial test and analysis, the Company currently estimates that it can deliver advanced (second generation) fuels from biomass at a cost of less than $ 2 per gallon of ethanol-equivalent fuel in facilities processing about 70,000 tonnes of b
The scope of the Likouala Swamp was a surprise and strongly suggests that it is a long way from giving up its secrets. There may even be theropods in there. In fact there should be theropods in there. There should be a lot of other interesting cri
Burying the Amazon in ash today would produce exactly the same local statistics. Thus this extinction event which stood out as a total global wipeout with no convincing explanation is reduced to a massive local event that caught up to the obvious
This clever bit of design has the merit that it emulates the original design but causes a major expansion of the effect. That makes it as clear as a bell. And their cheering is even clearer as it should.
LONDON – Stephen Hawking, the British mathematician and physicist famed for his work on black holes, was rushed to a hospital Monday and was seriously ill, Cambridge University said.
That we are looking at 2500 times input energy is a good sign that we will get a heat engine out of this yet. Yes, maybe it is time to get excited again. Try to catch the show tonight. With Robert Duncan doing an audit of the experimental protoco
Vourlidas says he is not surprised that CMEs resemble French pastries. "I have suspected this all along. The croissant shape is a natural result of twisted magnetic fields on the sun and is predicted by a majority of theoretical models."
I also want to observe that the clear reality of plate tectonics is not an answer either. This provides completely ironclad evidence of mass transfer from one side of a continental plate to the other side. Even allowing it to be forced by heat transf
The world owes Fleischmann and Pons a huge apology: The cold fusion technology they announced in 1989 -- which was blasted by arrogant hot fusion scientists as a fraud -- has been proven true once again by U.S. Navy Researchers
Large lions roamed North America and Europe as recently as 13,000 years ago, according to a new study published in Molecular Ecology. "These ancient lions were like a super-sized version of today's lions
Right on time the sunspot cycle is establishing minima. This time it appears to be as deep as last seen in 1913. Otherwise it is essentially good news as business as usual.
This work pretty well locks down the antiquity of maize husbandry. You have the natural heartland and direct evidence. It may and should be older still, but not by a lot. This age compares favorably with all other global domesticates
Joe Eck continues to find materials with higher Meissner Transitions which indicate superconductivity. Since we are now just a "stone's throw" from room temperature, he has placed this discovery into the public domain without patent pro
If this is accepted, then cold fusion comes immediately in from the cold and every imaginable strategy will be applied. It is about time that ample good science got done in this field. What happened in 1989 is a blot on scientific integrity. Rec
The press has almost forgotten our two rovers on their walk about on Mars. That they are still functioning is astonishing and they have made us at home on mars in a way that was never quite possible on the moon. That does suggest that we should sever
the Einstein@Home project is beginning to analyze data taken by the PALFA Consortium at the Arecibo Observatory in Puerto Rico. The Arecibo Observatory is the largest single-aperture radio telescope on the planet and is used for studies of pulsars
Alaska's Mount Redoubt volcano erupted five times overnight, sending an ash plume more than 9 miles into the air in the volcano's first emissions in nearly 20 years. Residents in the state's largest city were spared from falling ash, thou
Scientists are particularly concerned about the West Antarctic Ice Sheet, which has collapsed with great regularity about every 40,000 years and is currently in an unstable state. If all the ice atop West Antarctica today melted, it would raise world
The alga thrives in water up to 135 degrees Fahrenheit (too hot to shower) with a very acidic pH factor ranging from 0.5 to 3.5. Creeks are considered acidic if their pH factor is less than 7. "These algae live in areas of Yellowstone that ar
In all, 12 bacterial and six fungal colonies were detected, nine of which showed greater than 98 percent similarity with known species on Earth, the researchers said. Three bacterial colonies were deemed new species. Although the study doesn't c
I sort of liked the accompanying bit of art work. I cannot imagine it having any semblance of an image of the real thing but what the heck. That such binaries should exist is a given. Their closeness must provide the most amazing effects on galactic
Health expert Mike Adams points out, “The shocking answer is that this couldn’t have been an accident." This has received ZERO coverage in the US media.
