El neurocientífico canadiense Philip Low, ganó prominencia en la prensa científica después de presentar un proyecto con el físico Stephen Hawking, de 70 años. Low quiere ayudar a Hawking, que está completamente paralizado desde hace 40 años a causa de una enfermedad degenerativa, y es por ese motivo que sólo puede comunicarse con la mente. Los resultados del estudio fueron revelados el sábado pasado en una conferencia en Cambridge. Sin embargo, el propósito principal de la reunión era otro. En ella, los neurocientíficos de todo el mundo firmaron una petición afirmando que todos los mamíferos, aves y otras criaturas, incluyendo pulpos; tienen conciencia. Stephen Hawking estuvo presente en la cena de la firma del manifiesto como invitado de honor. Philip Low: “ ”. Low es un investigador de la Universidad de Stanford y de MIT (Massachusetts Institute of Technology), ambos lugares se encuentran en los Estados Unidos.
DNA: The Ultimate Hard Drive. When it comes to storing information, hard drives don't hold a candle to DNA.
Our genetic code packs billions of gigabytes into a single gram. A mere milligram of the molecule could encode the complete text of every book in the Library of Congress and have plenty of room to spare. All of this has been mostly theoretical—until now.

Chelsea Whyte, contributor The recent earthquakes in the Canary Islands of late aren't due to Poseidon the earth-shaker, but a submarine volcano to the south of the island of El Hierro.
Hot magma spewing from beneath the surface of the ocean has injected volcanic chemicals into the water, staining the sea green. Ocean waters have been churning with heat and seafloor sediment spewed from the volcano's plume, which stretches tens of kilometres under water. The eruption of magma is venting 50 to 100 meters below the surface, but catapulting volcanic rocks as high as 19 meters in the air. The volcanic activity is warming the waters by as much as 10 degrees Celsius, reports Red Orbit. Biology. Multimedia Gallery. NewScientist The Last Word - Index page. Bathed in heat I had a hot bath one evening and decided not to let all the heat go to waste.
So I left the plug in until the water had given up all of its heat to the house. Nature Publishing Group : science journals, jobs, and information. Instant Zombie – Just Add Salt. Those of you who follow me on Google+, facebook or twitter might have seen this neat little video: Yeah, it freaked me out, too.
But this little cephalopod isn’t actually alive – he’s just very freshly dead. A similar phenomenon can be seen in these frog legs: How are these dead body parts being brought back to life? These clever cooks are capitalizing on biology to put on a show. Nature Publishing Group : science journals, jobs, and information. Bacteria may communicate through nanowires. Some bacteria grow electrical hair that lets them link up in big biological circuits, possibly communicating and sharing energy.
“This is the first measurement of electron transport along biological nanowires produced by bacteria,” said Mohamed El-Naggar, assistant professor of physics and astronomy at the University of Southern California. He says that the discovery could help find ways to destroy harmful colonies, such as biofilms, and also help with the development of bacterial fuel cells. Scientists capture antimatter atoms in particle breakthrough.
Antihydrogen atoms were trapped in a magnetic fieldMatter and antimatter annihilate each other on contact"It's taken us five years to get here," says Professor Jeffrey HangstCERN's next ambition is to create a beam of antimatter (CNN) -- Scientists have captured antimatter atoms for the first time, a breakthrough that could eventually help us to understand the nature and origins of the universe.
Shocking Experiment Shows Talk Is Cheap. Engineers patch a heart: Tissue-engineering platform enables heart tissue to repair itself. Researchers at Columbia Engineering have established a new method to patch a damaged heart using a tissue-engineering platform that enables heart tissue to repair itself.
This breakthrough, recently published in the Proceedings of the National Academy of Sciences, is an important step forward in combating cardiovascular disease, one of the most serious health problems of our day. Led by Gordana Vunjak-Novakovic, Professor of Biomedical Engineering at Columbia University's Fu Foundation School of Engineering and Applied Science, the researchers developed a novel cell therapy to treat myocardial infarction (heart damage that follows a heart attack).
They were able, for the first time, to combine the use of human repair cells that were conditioned during in-vitro culture to maximize their ability to revascularize and improve blood flow to the infarcted tissue with a fully biological composite scaffold designed to deliver these cells to the damaged heart.
