Frozen Arctic soils hold vast stores of carbon that may exacerbate global warming. A NASA Arctic campaign is looking for signals that may hold a key to Earth's climate future.
Gust MEES's insight:
Ultimately, the scientists hope their observations will indicate whether an irreversible permafrost tipping point may be near at hand. While scientists don't yet believe the Arctic has reached that tipping point, no one knows for sure. "We hope CARVE may be able to find that 'smoking gun,' if one exists," Miller said.

Also, what else is interesting, is "telepathy," i.e., that "thoughts" (electromagnetic impulses) can travel any distance, know no barrier, and can be received at any distance - faster than the speed of light - in the twinkling of an eye.

Researchers at Stanford University School of Medicine have developed a new technique to see how different types of cells interact in a living mouse.
The process uses light-emitting proteins that glow when two types of cells come close together.
Using the technique, the team was able to pinpoint where in the body metastatic cancer cells ended up after they broke off from an initial tumor site, using readily available lab reagents. The team chose chemicals that are easily available in most life sciences laboratories because they wanted to develop a technique that could be widely used.

New research from the computer company Dell Inc. finds vast differences in attitudes to technology in education between China and the United States. While six in ten respondents in the United States do not approve of using social media in the classroom, a majority of Chinese respondents have positive feelings about the technology, the survey concluded.
Dell's education wing, Dell Edu, questioned almost 1,600 students, teachers, and parents in China, Germany, and the United States about their technology habits, and put the major findings in a nicely organized infographic (see below.) A report released with the survey also illustrated a few key differences on how technology is utilized for educational purposes:

Australischen Wissenschaftlern ist nach eigenen Angaben ein Durchbruch bei der Entwicklung künstlicher Augen gelungen. Einer Frau mit angeborener Netzhautdegeneration sei erfolgreich ein "früher Prototyp" eines bionischen Auges eingesetzt worden, teilte das australische Wissenschaftskonsortium Bionic Vision Australia (BVA) mit. Der Prototyp soll die Grundlage für das erste bionische Auge bilden, bei dem eine organische Fehlfunktion mittels technischer Sensorik überbrückt wird.

A technology that would enable low-cost, high efficiency solar cells to be made from virtually any semiconductor material has been developed by researchers with the U.S. Department of Energy (DOE)'s Lawrence Berkeley National Laboratory (Berkeley Lab) and the University of California (UC) Berkeley.
This technology opens the door to the use of plentiful, relatively inexpensive semiconductors, such as the promising metal oxides, sulfides and phosphides, that have been considered unsuitable for solar cells because it is so difficult to taylor their properties by chemical means.

The researchers say this technology is both easier and more cost-effective than the more invasive treatments commonly used. It’s potential use is particularly promising in brain cancer victims due to its non-invasive nature, the laser’s ability to go through thin bone like the skull, and the femtosecond laser radiation which according to Parigger helps, “avoid heating up too many other things that you do not want heated.
” Now that the technology has been developed, Parigger and his colleagues are in the process of commercializing it and making it widely available.

A ses origines, la Terre ne présentait pas vraiment de condition favorable à l'apparition de la vie. De nouveaux travaux étayent la théorie selon laquelle la vie sur Terre...
En revanche, des conditions plus extrêmes (485.000 - 610.000 bar, 3500 - 4500°C) entrainent la synthèse de méthane et de formaldéhyde, ainsi que des molécules carbonées à longue chaine. Ces composants sont des précurseurs des acides aminés et des composés organiques complexes. Des simulations de chocs thermodynamiques en laboratoire ont produit des quantités significatives de nouveaux composés carbonés azotés "prébiotiques" c'est-à-dire précurseurs de la vie. "Lors de leur impact, les comètes peuvent synthétiser des molécules prébiotiques sans nécessiter de conditions spéciales telles que des radiations ultraviolettes, des catalyseurs, ou de conditions préalables. ===> Ces donnéessont cruciales pour la compréhension du rôle des impacts cosmiques dans la formation des composés élémentaires de la vie sur Terre mais aussi sur d'autres planètes." <===

Researchers are designing tiny particles to act as medicine.
The particles are coated with waterlike molecules that allow them to travel inside the body without being detected by the immune system, Farokhzad said. Their surfaces contain molecules that provide them with a "GPS" to seek out abnormal cancer cells.
Once they find a cancer cell, the particles stick, and like a Trojan horse, the cancer cells take them inside where they can release medicine that's toxic to the cell, Farokhzad said. [Watch the World Science Festival Live.]
In a study published last year in Science Translational Medicine, Farokhzad and colleagues showed that, in people, the nanoparticles delivered a much higher dose of medicine to cancer cells than to other cells in the body. Follow-up studies will test the effectiveness of the drug at treating tumors.

Boire, être ivre, et retrouver son état normal très rapidement grâce à une pilule : la découverte de deux Américains fait fantasmer les fêtards et inquiète les alcoologues.
« La véritable application que je vois dans ce procédé est au niveau de la toxicologie. Lutter contre un coma éthylique par exemple. Aujourd’hui, pour faire sortir quelqu’un d’un coma, on augmente le volume de sang pour diluer la concentration d’alcool et laisser la dégradation naturelle par l’organisme faire son œuvre. On pourrait imaginer ici combiner ce procédé avec cette fameuse capsule. »
