Nobel prize in chemistry

Nobel in Chemistry Honors Expert on Surface Encounters
A German scientist whose studies of chemical reactions on solid surfaces have affected fields as diverse as agriculture, manufacturing and climatology won the Nobel Prize in Chemistry yesterday.

Gerhard Ertl, an emeritus professor at the Fritz Haber Institute of the Max Planck Society in Berlin, received the $1.5 million prize for pioneering work in surface chemistry, a specialty that helps explain the processes in making fertilizer and computer chips, and sheds light on the activity inside the catalytic converter of a car and on the surface of ice crystals in the stratosphere.

Nobel prize in physics

Disk technology takes Nobel Prize
French scientist Albert Fert and Peter Grunberg of Germany have won the 2007 Nobel Prize for physics.

They discovered the phenomenon of "giant magnetoresistance", in which weak magnetic changes give rise to big differences in electrical resistance.

The knowledge has allowed industry to develop sensitive reading tools to pull data off hard drives in computers, iPods and other digital devices.

It has made it possible to radically miniaturise hard disks in recent years.


Well, that's good timing. I just wrote about the field of disk technology here. That article isn't about giant magnetoresistance per se, but that part of physics is certainly an important part of the big picture.

Here are other reports on the news:

Nobel prize recognizes GMR pioneers
Giant magnetoresistance, or GMR, is the sudden change in electrical resistance that occurs when a material consisting of alternating ferromagnetic and non-magnetic metal layers is exposed to a sufficiently high magnetic field. In particular, the resistance becomes much lower if the magnetization in neighbouring layers is parallel and much higher if it is antiparallel. This change in resistance is due to "spin up" and "spin down" electrons scattering differently in the individual layers.

GMR has since been used to develop extremely small and sensitive read heads for magnetic hard-disk drives. These have allowed an individual data bit to be stored in a much smaller area on a disk, boosting the storage capacity greatly. The first commercial read heads based on GMR were launched by IBM in 1997 and GMR is now a standard technology found in nearly all computers worldwide and is also used in some digital cameras and MP3 players.

Nobel prize in physiology/medicine

It's Nobel season, so I'll take a bit of time to pass along the news as it comes out. Of course, you'll get the same basic information from whatever other news sources you pay attention to, but I'll try to point you to something that talks more about the underlying science than you'll get from the mass media. Here's a good place to start:

Capecchi, Smithies and Evans share the Nobel
Mario Capecchi of the University of Utah, Sir Martin Evans of Cardiff University in the UK and Oliver Smithies of University of North Carolina, Chapel Hill, will share this year's Nobel Prize in Physiology or Medicine for their work in gene manipulation that let to the development of knockout mice.
