Relativistic Heavy Ion Collider

The Spin Puzzle RHIC is the world's only machine capable of colliding beams of polarized protons to investigate the 'missing' spin of the proton. Electron-Ion Collider A breakthrough accelerator could collide electrons with heavy ions or protons at nearly the speed of light to create “snapshots” of the force binding all visible matter. Accelerator Science Before high-speed packets of heavy ions can be brought into collisions with one another, they first travel through a chain of smaller particle accelerators. An Educational Pipeline Large-scale physics facilities like RHIC play a significant role in training the next generation of physicists. A Compelling Future for RHIC.

University > SCC-RI > Mick Bhatia

Bhatia’s program seeks to understand the molecular mechanisms that govern somatic and pluripotent human stem cell development through; 1) characterization of molecular pathways and genomic targets that regulate hematopoietic and pluripotent stem cells differentiation, and 2) use novel in vivo models for cellular/tissue regeneration through xeno-transplantation. Program Outline Characterization of molecular pathways regulating human hematopoietic and pluripotent stem cells including Notch, Sonic Hedgehog, Bone Morphogenetic Proteins, and human Wingless homologs involved in Wnt signaling transduction.

For new readers, this collection of “missing links” rounds up fascinating stuff I find around the internet, and appears every Saturday.

Not Exactly Rocket Science

It’s separated into Top Picks (the best stuff), Science/News/Writing (science writing), Heh/Wow/Huh (silliness, satire, photos, videos), and Journalism/Internet/Society (a miscellany of my other interests). If links are broken, let me know in the comments. Top picks “Restless genes” by David Dobbs, about the genetics and other factors behind the human urge to explore, is one of the best science stories of the year, let alone the week. It’s beautifully written without sacrificing nuance. Giant crabs are marching on Antarctica.

Quand les scientifiques se mettent a bloguer… Qui sont les Chimistes pour l'Environnement ? - Chimistes pour l'environnement. Créé en mai 2006, nous sommes un comité environnemental qui œuvre au sein du département de chimie de l'Université Laval afin de promouvoir le développement durable et de sensibiliser les membres du département à cet aspect de leur travail ou de leurs études. Carnet de recherche visuel, par André Gunthert. Au lendemain de la victoire de François Hollande aux primaires socialistes, Libération ornait sa Une d’une photo laudative de Sébastien Calvet (voir ci-contre) – tout en niant fermement, par la voix de Sylvain Bourmeau, toute orientation politique dans ce choix décrit comme purement esthétique.

Carnet de recherche visuel, par André Gunthert

Même si le recul permet aujourd’hui de mieux percevoir ce que cette option éditoriale pouvait avoir de propagandiste, le message porté par l’image n’est jamais limpide ni univoque. Comme le montre la discussion développée sous mon billet de l’époque, des lectures divergentes pouvaient s’exprimer sans qu’il soit possible de trancher de manière définitive dans un sens ou un autre.

Is technology part of the problem – and could it also be part of the solution? Dave Coplin, Chief Envisioning Officer at Microsoft, imagines what might be possible if more organisations embraced the full, empowering potential of technology and encouraged a truly open, collaborative and flexible working culture.

Chemistry Blog » Blog Archive » How Water Freezes Lower on a Negatively Charged Surface

In short, David Ehre, Etay Lavert, Meir Lahav, and Igor Lubomirsky report in Science, (Water Freezes Differently on Positively and Negatively Charged Surfaces of Pyroelectric Materials) water freezes at a lower temperature (-18°C) on the negatively charged side of a lithium tantalate plate with a strontium titanate film than on the positive side (-7°C, and -12°C uncharged). Is this unique or is this a manifestation of something in our standard introductory organic chemistry textbooks? I thought it was the latter. Let me explain how. For the purpose of thinking about this problem, let us assume the metal surface is simply a flat charged surface, without contour. If we compare with the positively charged surface, then both pairs of non-bonded electrons should be anchored to the surface and locking the hydrogens in a fixed position. I could have drawn a model with two attachments points for water. Intellicore Tech Talks - intellicore. Le blogging scientifique.
