Curiosity sends high-resolution color images from Gale Crater
NASA's Curiosity rover has shipped back to Earth high-resolution color images of its surroundings on Mars, sharpening our views of an intriguing channel, layered buttes and a layer of cobbles and pebbles embedded in a finer matrix of material.
Pier Oddone to step down as Fermilab director
Fermilab Director Pier Oddone has decided to retire after eight years at the helm of America’s leading particle physics laboratory. Oddone will continue to serve as Fermilab director until July 1, 2013, while a committee appointed by the FRA Board Chairman conducts an international search for his successor.
Researchers’ insight on ‘pseudogap’ an important advance
More than two decades after scientists discovered a new type of copper-based high-temperature superconductor — energy-efficient material that can carry electricity without waste — Harvard physicists say they have unlocked the chemical secret that controls its “fool’s gold” phase, which mimics, but doesn’t have all the advantageous properties of, superconductivity.
MagLab receives renewal grant
A decision by the National Science Board (NSB) to award a five-year renewal grant to the National High Magnetic Field Laboratory (MagLab) will enable Florida and New Mexico to continue as research meccas for leading physicists, chemists, biologists and engineers from around the world.

Helium II
Helium II (He II) refers to the second liquid phase of the most abundant helium isotope (4He). Helium II is also referred to as superfluid helium. Helium II occurs once the temperature of the liquid helium drops below 2.17K. The phase transition between the first liquid phase of Helium (referred...

Bose-Einstein Condensate
A Bose-Einstein condensate, first proposed in 1925 by Albert Einstein based on work done by Satyendra Nath Bose (the same Bose from whom the term boson is derived), is a super-cold state of matter in which almost all of the individual atoms have “condensed” down to the lowest possible quantum...
Cold Technology for Pest Control
While it does not reach temperatures cold enough to be called cryogenic, carbon dioxide snow is at the heart of a new way of dealing with unwanted pests. It utilizes a quick freezing process that takes advantage of the properties of carbon dioxide snow and has a number of benefits...
Cryogenic Finishing
The following 3 articles discuss the uses and procedures of various type of cryogenic finishing. 1) By Robin A. Rhodes, Cryogenic Institute of New England, Inc. rrhodes@nitrofreeze.com Cryogenic Deflashing is employed to remove undesired residual mold flash that remains on molded parts after they are removed or ejected from the...
Dry ice vs. LN2 for preserving tissue
I was wondering if anyone could provide feedback/data on whether it is best in terms of preserving tissue quality to freeze tissue in OCT using dry ice versus liquid nitrogen?
Are there lists of existing biorepositories?
We are a relatively new Biorepository that was developed as part of a large breast cancer epidemiology study, and thus far we have accumulated DNA on over 8000 women along with extensive questionnaire, mammography, and case status data. I was wondering, are there lists of existing Biorepositories with their contents?...
Heat flux value for inner vessel when vacuum insulation fails
To size a relief valve for a LN2 cryostat I have to know “worse case” boil-off rate when vacuum insulation failed and inner vessel with LN2 is in direct contact with room temperature air at 300K. So, I am looking for a heat flux value (watt/m2) to LN2 inner vessel...
Trying to design a system to store ammonia at -33°C
I am working on a project where we are trying to design a system to store ammonia at -33°C. In order to size the compressors to maintain the ammonia in the liquid state, I need to estimate the heat gained from the environment including the radiation from the sun and...
