Mini Museum by Hans Fex The successful funding of my Kickstarter campaign has allowed me to pursue my life long dream of bringing the mini museum to the world. I want to thank all of the backers and the entire Kickstarter community. I also want to thank my family and friends. Without their love and continued support, this project could not become a reality. I am so grateful. I'd also like to welcome you to visit minimuseum.com where you can sign up for special email updates. The mini museum is a portable collection of curiosities where every item is authentic, iconic and labeled. The collection starts with some of the oldest matter ever collected in the known Universe - matter collected from carbonaceous chondrites. What's next? As we migrate from the beginning of the Universe to early life on Earth, we discover Homo Sapiens. It's space and time in the palm of your hand. The Universe is amazing. The mini museum is a portable learning tool, a smart and rare ice breaker, and a wonderful piece of historical art.
This is an animation of DNA replication by DNA polymerase and accurately shows the function of all its subunits Dance of the Hundred Thousand Asteroids You can watch this video and just be mesmerized by the depiction of every asteroid observed by the Sloan Digital Sky Survey. On the other hand, you can also use it as a way to understand important facts about the solar system and the way gravity affects objects. For a start, the video gives you some sense of just how many objects there are out there large enough to be tracked, in a way the dry figure of “more than 100,000” probably doesn't. It also becomes clear that most inner solar system objects sit in the asteroid belt, not only lying between Mars and Jupiter, but in a relatively flat plane. The Trojan asteroids are also visible, their clumping a puzzle until you realize that Jupiter lies between the two groups, with one 60 degrees ahead and the other 60 degrees apart. The video's maker, Alex Parker, has color coded the asteroids by families, for example with Jupiter's Trojans in red and the inner main belt in green.

Synthetic magnetic monopoles have been created in the lab A magnet always has a north and a south pole. Even if a magnet is cut in half down to the atomic level, magnetic fields are bipolar. However, in 1931 it was theorized that there are natural monopoles which help explain some of the peculiarities of magnetism. Hall’s lab was able to create the monopole particles by chilling rubidium atoms to less than 100-billionths of a degree warmer than absolute zero. For the first time, physicists will be able to test the theories laid out by Paul Dirac 83 years ago. Just because these monopole particles have been created in the lab does not necessarily mean that they exist in nature, but if they do, researchers will now have a better idea of what to look for.
Un nouveau virus géant, âgé de plus de 30 000 ans, découvert en Sibérie Un nouveau type de virus géant a survécu plus de trente mille ans à la congélation, dans une couche de permafrost sibérien contemporaine de l'extinction de l'homme de Neandertal, selon une étude publiée dans les comptes rendus de l'Académie des sciences américaines, les PNAS, lundi 2 mars. Baptisé Pithovirus, ce virus très ancien, capable d'infecter des amibes mais inoffensif pour l'homme et les animaux, porte désormais à trois le nombre de familles connues de virus géants. Découvert dans le sol gelé en permanence de l'extrême Nord-Est sibérien, Pithovirus est bien différent des autres virus géants, comme les Mimivirus, découverts en 2003 en Grande-Bretagne, ou les Pandoravirus, décrits dans la revue Science en juillet 2013. Son génome, de moins de 500 gènes, est notamment plus petit que celui du Pandoravirus, qui en a plus de 2 500. Les virus géants, d'un diamètre supérieur à 0,5 millionième de mètre, sont aisément visibles avec un simple microscope optique. Le Monde avec AFP
If the Moon Were Only 1 Pixel - A tediously accurate map of the solar system Mercury Venus Earth You Are Here Moon Mars Jupiter Io Europa Ganymede Callisto Saturn Titan Uranus Neptune Pluto(we still love you) That was about 10 million km (6,213,710 mi) just now. Pretty empty out here. Here comes our first planet... As it turns out, things are pretty far apart. We’ll be coming up on a new planet soon. Most of space is just space. Halfway home. Destination: Mars! It would take about seven months to travel this distance in a spaceship. Sit back and relax. When are we gonna be there? Seriously. This is where we might at least see some asteroids to wake us up. I spy, with my little eye... something black. If you were on a road trip, driving at 75mi/hr, it would have taken you over 500 years to get here from earth. All these distances are just averages, mind you. If you plan it right, you can actually move relatively quickly between planets. Pretty close to Jupiter now. Sorry. Lots of time to think out here... Pop the champagne! We're always trying to come up with metaphors for big numbers.
How an automotive gas engine works Can You Trust Your Johnson? Scientists Claim They Are Close To Cloning A Mammoth Researchers examining easily the best preserved mammoth ever found believe it may be possible to clone the individual and bring the extinct species back to life. However, they acknowledge that what would be produced would not be the same creature as what went extinct 4000 years ago. They have also sounded a note of caution on the ethics of such an operation. The cold temperatures in which mammoths lived and died mean they are often much better preserved than other species of equivalent age - but a specimen found last year in the Sakha Republic, eastern Siberia, is an exceptional case even for mammoths. “We have dissected the soft tissues of the mammoth - and I must say that we didn't expect such results. It is thought the mammoth fell into an ice cave and while the top section was eaten by animals, the legs, trunk and some of the internal organs are very well preserved. Khayrullin was quick to endorse the importance of a considering the implications of such a big move. Photo Gallery
Première détection des ondes gravitationnelles du Big Bang Les fluctuations du rayonnement cosmologiqueLa nouvelle vient du froid et ouvre un nouveau chapître de la physique, de la cosmologie et de notre vision de l'Univers. Un radiotélescope a réussi à pêcher dans un rayonnement émis 380.000 ans après le Big bang, la trace de tremblements de l'Espace-Temps qui ont secoué l'Univers où nous vivons - l'Univers observable - durant la première seconde après le Big Bang. C'est une équipe internationale, surtout américaine de Harvard, Caltech, Stanford, etc, et canadienne, dirigée par John Kovac mais elle comporte aussi deux chercheurs français (Lionel Duband du CEA, CEA Grenoble et Denis Barkats de l'Observatoire européen austral), qui vient de faire cette annonce spectaculaire dans Nature news, lors d'une conférence qui a saturé les réseaux des laboratoires d'astrophysique du monde entier. BICEP-2 a étudié 1% du ciel Pour Cécile Renaut (Cnrs, LPSC Grenoble), «c'est un résultat magnifique, majeur pour la cosmologie. Einstein avait raison Sur le blog:
Depuis le pôle sud, des échos du Big Bang LE MONDE | • Mis à jour le | Par David Larousserie Voilà un signal que n’ont pu écouter ni l’Agence de sécurité nationale américaine (NSA) ni tout autre service de renseignements. Pourtant les informations qu’il contient sont d’une extrême importance. Ces soubresauts sont des ondes gravitationnelles primordiales et n’avaient jamais été observés. Le télescope Bicep2 n’a pas directement observé ces ondes gravitationnelles primordiales mais il en a constaté l’effet sur un rayonnement qui a fait la « une » des médias il y a tout juste un an : le rayonnement du fond diffus cosmologique. C’était 380 000 ans après le Big Bang. Mais ces messagers de lumière ayant parcouru un si long chemin n’avaient pas tout dit. C’est ce qui a été vu pour la première fois par Bicep2. « Ce qui est beau, c’est moins les ondes gravitationnelles elles-mêmes que leur origine quantique », estime Thibault Damour, professeur à l’Institut des hautes études scientifiques (Bures-sur-Yvette, Essonne).
