UK science budget safe – for now
The threat of budget cuts has created quite a buzz in the UK science community, but an announcement made yesterday assured scientists that funds will be frozen at £4.6 billion for the next four years.

“Mr. Freeze” brings cryogenics to home-schooled students
The Post-Tribune reported that Fermilab's "Mr. Freeze" gave a cryogenics demonstration to a group of home-schooled students at the South Lake Church of the Nazarene in Crown Point IN.
NIF completes first successful integrated experiment
The National Ignition Facility (NIF) recently completed its first integrated ignition experiment, which marks the beginning of its next phase on the way toward fusion ignition tests.
Update to “Gathering Storm” report released
The US National Academy of Sciences, the US National Academy of Engineering and the Institute of Medicine have released an update to the 2005 "Rising Above the Gathering Storm" report.

Dewar
A dewar is a type of cryostat named after Sir James Dewar, the researcher who first developed the concept of a vacuum insulated container with silvered walls to reflect thermal radiation. Dewar was the first to liquefy hydrogen, and he created the device to store his discovery. The thermos bottle...
Stirling and Gifford-McMahon Cryocoolers
Stirling and Gifford-McMahon (GM) cryocoolers are two of the most commonly used cryocoolers in cryogenics. Both devices have a significant industrial base and operate at a wide range of temperatures and capacities. The thermodynamic cycles for both of these cryocoolers are quite similar. The Stirling cycle consists of a compressor,...
Liquefied Natural Gas (LNG)
A significant commercial application of cryogenics is the liquefaction, transport and storage of natural gas. Liquefied Natural Gas (LNG) is generally 95 percent methane with a few percent ethane and much lower concentrations of propane and butane. LNG liquefies at 111.6 K. Unlike many applications of cryogenics, the motivation for...
Cryogenic Electronics
Randall Kirschman, consulting physicist, Mountain View, California ExtElect@gmail.com Cryogenic electronics—the operation of electronic devices, circuits, and systems at cryogenic temperatures—has been a valuable technology for decades. Cryogenic electronics (also referred to as low-temperature electronics, or cold electronics) can be based on semiconductive devices, on superconductive devices, or on a combination...
Particle Physics: High Energy Physics
Cryogenics and High-Energy Physics 1. From symmetry magazine: http://www.symmetrymagazine.org/cms/?pid=1000627: Cryogenics is the study of how materials behave at temperatures near absolute zero. In high-energy particle accelerators, such frigid temperatures reduce the electrical resistance of wires in superconducting magnets, increasing the magnet strength and allowing faster particle acceleration. The same holds...
HTS Degaussing Systems
From the Spring 2009 issue of Cold Facts (Volume 25, Number 2): Thanks to a joint project by the US Navy and a number of industry partners, high temperature superconducting (HTS) technology is now at the heart of an advanced degaussing system aboard the USS Higgins at the naval station...
Magnetic Resonance Imaging
From http://www.superconductors.org: An area where superconductors can perform a life-saving function is in the field of biomagnetism. Doctors need a non-invasive means of determining what’s going on inside the human body. By impinging a strong superconductor-derived magnetic field into the body, hydrogen atoms that exist in the body’s water and...
Effect of cryogenic freezing on tone of bell?
I have been making bells for a few years out of Bell Bronze, 87% Copper. Would cryogenic freezing have any effect on the tone of a bell if I had it treated after casting? Your help would be appreciated.
Thermal conductivity of niobium, tantalum, lead, tin
I am interested in the thermal conductivity and other properties of low temperature superconductors. Specifically I am interested in materials like Niobium, Tantalum, Lead and Tin. Would you know of a publication that dealt with thermal properties in general and also gave specific data on these materials?
Could boxes of paper records be freeze-dried?
In the event of a disaster such as a flood, could boxes of paper records be freeze-dried? Could cryogenics help in the recovery efforts?
Where can the cryogenic insulator trade be studied?
I have been searching for information regarding the training of cryogenic insulators and have not been able to find any information in North America.
