No known hominin is common ancestor of Neanderthals and modern humans, study suggests -- ScienceDaily The search for a common ancestor linking modern humans with the Neanderthals who lived in Europe thousands of years ago has been a compelling subject for research. But a new study suggests the quest isn't nearly complete. The researchers, using quantitative methods focused on the shape of dental fossils, find that none of the usual suspects fits the expected profile of an ancestor of Neanderthals and modern humans. They also present evidence that the lines that led to Neanderthals and modern humans diverged nearly 1 million years ago, much earlier than studies based on molecular evidence have suggested. The study, which will be published online this week by the Proceedings of the National Academy of Sciences, was carried out by an international team of scholars from The George Washington University, Konrad Lorenz Institute for Evolution and Cognition Research in Austria, Indiana University and Atapuerca Research Team in Spain.

In some genes the protein-coding sections of the DNA ("exons") are interrupted by non-coding regions ("introns"). RNA splicing removes the introns from pre mRNA to produce the final set of instructions for the protein. Transcript: As DNA is transcribed into RNA it needs to be edited to remove non-coding regions, or introns, shown in green. This editing process is called splicing, which involves removing the introns, leaving only the yellow, protein-coding regions, called exons. RNA splicing begins with assembly of helper proteins at the intron/exon borders. This process is repeated for every intron in the RNA.
European Neanderthals were on the verge of extinction even before the arrival of modern humans New findings from an international team of researchers show that most Neanderthals in Europe died off around 50,000 years ago. The previously held view of a Europe populated by a stable Neanderthal population for hundreds of thousands of years up until modern humans arrived must therefore be revised. This new perspective on the Neanderthals comes from a study of ancient DNA published February 25 in Molecular Biology and Evolution. The results indicate that most Neanderthals in Europe died off as early as 50,000 years ago. The study is the result of an international project led by Swedish and Spanish researchers in Uppsala, Stockholm and Madrid. “The fact that Neanderthals in Europe were nearly extinct, but then recovered, and that all this took place long before they came into contact with modern humans came as a complete surprise to us.

Science Hack Day / NightISS Image classification of night time images taken from the International Space Station Alejandro Sánchez de Miguel, et al. Universidad Complutense de Madrid. Image classification: Right now there are around 1.800.000 images at the Johnson Space Center database (The Gateway of the Astronauts). Our main objective it's to study the light pollution that came from the cities. Moreover, on the research of night time images they also interesting those containing star fields (Zamorano et al. 2011). Automatic classification techniques of images: Classification based on the ISS nadir position: The vertical of the ISS it is a point called Nadir. Although, these positions are only a first approximation and the place that have been captured can be beyond 300 km (187 miles). This position can be used to classify the images taken from the ISS. The first attempt to compute the image position is to know if ISS nadir is on the night side of the earth. This technique was explored by J. Images of stars: Aperture.
The Animal Files Neanderthals died out earlier than previously thought, new evidence suggests Direct dating of a fossil of a Neanderthal infant suggests that Neanderthals probably died out earlier than previously thought. Researchers have dated a Neanderthal fossil discovered in a significant cave site in Russia in the northern Caucasus, and found it to be 10,000 years older than previous research had suggested. This new evidence throws into doubt the theory that Neanderthals and modern humans interacted for thousands of years. Instead, the researchers believe any co-existence between Neanderthals and modern humans is likely to have been much more restricted, perhaps a few hundred years. It could even mean that in some areas Neanderthals had become extinct before anatomically modern humans moved out of Africa. The research, directed by the University of Oxford and University College Cork in collaboration with the Laboratory of Prehistory at St Petersburg, Russia, and funded by Science Foundation Ireland was recently published in PNAS Online Early Edition.
Irish Genealogy News: TIGS transcribes NY burial records with place of origin A unique and valuable new resource has resulted from a project managed by Troy Irish Genealogy Society (TIGS): transcriptions of 12,731 records from the recently rediscovered interment book for St John's Cemetery in Albany, NY. Just under one third (3,895) of the records relate to Irish-born individuals and, remarkably, all but 500 entries identify the county from which they originate. This collection, which contains records from 1841 to the late 1880s, could throw open the research doors to many Americans descended from Irish immigrants who fled the famine. Here's a breakdown of the Irish identified in the interment records with their home county in Ireland: The records, along with further details of the cemetery and how the book was rediscovered, are freely searchable on the Troy Irish Genealogy Society website. Take a look, too, at their other transcription projects, while you're at it. Hearty congratulations to the Society and its members for making these priceless records available.
Favourite maps from 2013 Everyone and their dog tends to publish their own 'best maps of...'. Given I spend most of my time on this blog haranguing bad maps during the year I thought I might try it myself this year so here goes, in no particular order...my favourite 10 maps of 2013. For those that are counting, there's 11 but here goes... NYCHenge by Andrew Hill The Manhattan Solstice occurs twice a year when the setting sun aligns perfectly with the east-west street grid in New York City. This map could not be any simpler but it captures the phenomena perfectly. Population Lines by James Cheshire Global population density drawn as horizontal lines...almost like a cardiograph of the pulse of the world's populus. Tornado Days by Brenden Heberton 2013 saw any number of maps made using NOAA's historical tornado data but this example did a fantastic job of going beyond the map by combining a wide range of multimedia in an innovative way.

Bunnies implicated in the demise of Neanderthals - 27 February 2013 BLAME it on the bunnies. The debate over what Neanderthals ate, and how it may have led to their demise, has turned to rabbits. Which, it is now claimed, they did not feast on. Signs that our extinct cousins hunted dolphins and seals were presented in 2008 as evidence of their sophistication. But, experts claimed in 2009, they weren't clever enough to catch fish or birds – which could have given our ancestors an edge. Now, John Fa of the Durrell Wildlife Conservation Trust in Trinity, Jersey, says the remains in caves around Europe became dominated by rabbits rather than large game around the time Neanderthals went extinct (Journal of Human Evolution, doi.org/kkn). It's not clear why they would have had more trouble changing prey, says Fa.

Our Favorite Maps of 2013 The digital maps we loved in 2013 didn't simply illustrate novel or useful information (how people travel, where they live, what it means to live without much money). They did it in ways we'd never seen before, manipulating time, dimensions, perspective, even the atmosphere. These maps weren't just interesting in content; they were innovative in design. That's our new bar for 2014. So this December, instead of sharing our top 10 maps of the year, we're looking at 10 ways we've learned to think about maps in entirely new ways. This may well have been the year when maps ceased to impress us for what they convey and began to stun us instead for how they did it. 1. Mapbox 2. Google Maps 3. Global Bike Share Map 4.
