3:01 AM | Un ‘jardín secreto’ bajo el hielo de la Antártida
Un grupo de investigadores estadounidenses ha encontrado a 800 metros de profundidad, bajo el hielo antártico, un verdadero vergel de vida microbiana que sobrevive en un ecosistema de total ausencia de luz y a temperaturas por debajo de los cero grados centígrados. El hallazgo tendrá implicaciones para la búsqueda de vida en ambientes extremos, tanto dentro como fuera de la Tierra. Bajo el espeso hielo de la Antártida bulle la vida microbiana. Así se […]

11:00 PM | 19,000 Years Ago, Arctic Sea Ice Influenced Force Of The Gulf Stream
Researchers have succeeded in reconstructing the sea ice conditions in the Fram Strait for this critical period at the end of the last glacial and thus in finding a direct connection between changes in sea ice cover and fluctuations in the Gulf Stream. A nine meter long sediment core served as a window into the past for the geologists. It was drilled on a Fram Strait expedition conducted on the research vessel Maria. S. Merian and has such clearly defined layers that the scientists can read it […]

11:00 PM | Type 1 And 2 Diabetes Caused By Same Amylin Hormone Mechanism
A new study has found that both type-1 diabetes and type-2 diabetes are the result of the same mechanism - the formation of toxic clumps of a hormone called amylin. The results, based on 20 years' work in New Zealand, suggest that type-1 and type-2 diabetes could both be slowed down and potentially reversed by medicines that stop amylin forming these toxic clumps. As well as producing insulin, cells in the pancreas also produce another hormone called amylin. Insulin and amylin normally work […]

10:24 PM | How Guardians Of The Intestinal Galaxy Are Formed
Even the most careful chosen meal can contain surprises and to defend against infectious microbial fifth columnists in the intestines, a dedicated contingent of immune cells keeps watch within the thin layer of tissue that divides the contents of the gut from the body itself.  New research at Rockefeller University sheds light on the development of a unique class of immune cells known as intraepithelial lymphocytes (IELs) that reside in this critical interface. . read more

9:58 PM | How Much Is A $100 Worth In Your State?
If you’ve ever traveled outside of the country, you’ve probably had to exchange your U.S. dollars for the currency of the country you’re visiting. Based on the exchange rate, your money usually becomes more valuable (unless you’re traveling to Europe). But while we don’t typically think about our money having different values when we travel within the U.S., there are actually huge differences in purchasing power from one state to […]

7:52 PM | How A Parisian Engineer Revealed The Mona Lisa’s 500-Year Old Secrets
The Mona Lisa is arguably the most iconic and well-known piece of art in the world. In December of 1962, just before the painting began a tour of the United States, The Louvre (the French Museum that serves as the painting’s permanent home) had an insurance assessment done on the painting: it was valued at a whopping $100 million. In today’s dollars (accounting for inflation), that’s around $780 million. Take into account that the painting has only been increasing in

6:32 PM | Man versus Octopus
We cannot yet define consciousness without tautology or hand-waving, but we have learned enough to devise a few supportable statements about it: 1. it happens inside the brain 2. more than one neuron is involved at any given point So, it's in one place (the brain), but it's not in one place (many neurons) ... The unitaryness of consciousness is an illusion. That my consciousness feels singular is merely a manageable fiction. The prefrontal cortex demands it thus. The neocortex... Read more

Topic for this TED Talk: Save the Urchin Fishery With This One Weird Trick! Unregulated Sea Urchin fishery has left Maine struggling to recover its sea urchin population. Over the years, this precious resource has been exhausted and left unrecovered. A little to few sea urchin species has been spawning in the gulfs of Maine and is reaching alarmingly low levels. Graham Morehead here talks of a possible solution to this concern. In this video, Graham was invited at TEDxYouth@Biddeford... Read […]

6:27 PM | Complexity Is Not Complicated: Graham Morehead at TEDxUMaine
This talk was given by Graham Morehead, Curator of The Pangeon at the 2014 TEDxUMaine. A man rots unjustly in jail, the sea urchins are dying, and Google Translate doesn't work. Morehead ties together these three disjoint narratives using starlings. His talk tackles the concept of a complex system. Being complex is not the same as being complicated. Even though no entity within a system can see the whole picture, undeniable large-scale patterns emerge from the system. As we learn... Read more

5:30 PM | Calcium And Reproduction Go Together In Flowering Plants
Everyone's heard of the birds and the bees - why do they leave out the flowers that are being fertilized? Maybe because it is too complicated. The fertilization process for flowering plants is particularly complex and requires extensive communication between the male and female reproductive cells. New research from an international team reports in Nature Communications about discoveries in the chemical signaling process that guides flowering plant fertilization. read more

5:00 PM | Extinction Level Events
I spent 5 days in Washington, D.C. last week with my family. We biked the mall to see the various monuments. We selectively toured some Smithsonia (or is it Smithsonians?); check the Facebook page for that album, including the Hall of Human Origins exhibit. We hadn’t really inherited anything recently, so we slept on the floor of one of my wife’s grad school buddies. Oh, and my son attended the World Pokemon Championships, not as a contestant, but as a fanboy […]

3:10 PM | Quantum Inside Cold Helium Nanodroplets Mapped
Scientists have mapped quantum tornadoes that swirl within tiny droplets of liquid helium, which confirms that helium nanodroplets are in fact the smallest possible superfluidic objects and opens new avenues to study quantum rotation. Superfluid helium has long captured scientist's imagination since its discovery in the 1930s. Unlike normal fluids, superfluids have no viscosity, a feature that leads to strange and sometimes unexpected properties such as crawling up the walls of containers or […]

1:00 PM | Quantum Mechanics: Why We Respirate Rather Than Asphyxiate
By Peter Gwynne, Inside ScienceWhy don't we suffocate whenever we try to take a breath? An international team of scientists has used quantum mechanics – the science that usually deals with events at the level of the ultra-small – to solve this human-sized mystery.Quantum mechanics has long proved its value in understanding such phenomena as the behavior of electrons and in classifying subatomic particles. But in recent years theorists have increasingly shown how it applies to all […]

Congratulations, you’re a Time Lord. Are you excited for the return of Doctor Who? Of course you are, that was a dumb question. What if I told you that you have the power to regenerate, just like a Time Lord? Well, not just like a Time Lord, because it doesn’t involve glowing, gilded streams of life force shooting out of every orifice, but pretty close. Head over to Nerdist to read my friend Kyle’s new article (it’s an awesome blend of science and sci-fi) detailing […]
