More beholden to magnetism than gravity

What would happen if you tried to hit a baseball pitched at 90% the speed of light?

Kind of like a zit, but full of plasma.

One of the most enduring mysteries in solar physics is why the Sun's outer atmosphere, or corona, is millions of degrees hotter than its surface. - Now scientists believe they have discovered a major source of hot gas that replenishes the corona

The Ban on Blood Donation

Are the Rules That Determine Who Can Donate Blood Discriminatory? Canadian AIDS researchers Dr. Mark Wainberg and Dr. Norbert Gilmore say that while the ban on blood donation from men who have sex with other men may have been ethically and scientifically justified in the 1980's, it no longer makes sense. (CMAJ.) Even though the US FDA reaffirmed their long-standing ban in 2007, they plan to revisit the policy in June. [more inside]

The Sun Is a Miasma of Incandescent Plasma

...the lyrics to that last song were basically taken from an encyclopedia written in the 50s, and since the 50s, some remarkable things have happened...
In 1959, a number of songs about science were released on an album called Space Songs. One of these was later covered by the band They Might Be Giants: Why Does The Sun Shine? (The Sun Is A Mass of Incandescent Gas). Only one problem: it isn't--the song was based on an incorrect text from 1951. So they wrote an answer song to themselves: Why Does The Sun Really Shine? (The Sun Is a Miasma of Incandescent Plasma). Bonus link: see for yourself! (previously)

Quark-Gluon Plasma

The ALICE Collaboration is building a dedicated heavy-ion detector to exploit the unique physics potential of nucleus-nucleus interactions at LHC energies. The aim is to study the physics of strongly interacting matter at extreme energy densities, where the formation of a new phase of matter, the quark-gluon plasma, is expected. This website aims both at introducing non-initiates to the field of physics covered by ALICE and at providing regular information on the evolution of the experiment, with detailed reports of its results and analysis.

Converting Garbage into Energy

Mr Fusion - coming soon. Startech Environmental Corporation's "Plasma Converter" works like "the big bang in reverse," creating nothing out of something. With the ability to break down any type of material (other than nuclear waste) into component molecules and and actually generate energy in the process, we may be at the twilight of the landfill industry. Via.

Blood, sweat and tears

Is blood plasma salinity the same as seawater? No, but that proves evolution. "The answer is most definitely NOT that oceans were 1/3 as salty back then. It most definitely IS that the earliest vertebrates did evolve in salt water and then moved into fresh water....They have devised an extremely clever trick in kidney structure to allow salt transport pumps which really take salt back INTO the body from the urine but still manage to use them to produce urine much more concentrated that their body fluids and so excrete salt FROM the body."

Blood for oil

"Blood for oil" seems to be the new cry on campus (or at least "Plasma for gas").

Graphite, a microwave oven, and thou.

Foudre en Boule avec des micro-ondes (Making ball lightning in your microwave). Complete with movies and audio spectrum analyses. From the Plasma Research website. Also: how to build a stable plasmoid in your microwave; simple ball lightning generation in your microwave; and, last but certainly not least, how to build yourself a glow discharge plasma panel. "This panel is not able to generate some thrusting effects, but you will be able to explore some OAUGDP properties like the air drag reduction effect and to test the EM Cloacking effect."

Blood Substitute.

Loyola University has received approval to investigate PolyHeme®'s use as a blood substitute for critically injured and bleeding trauma patients at accident scenes. Blood has a very short shelf life, requires refrigeration, and matching types takes too much time too carry blood in ambulances. The blood substitute has a long shelf life and is compatible with all blood types. It's designed to furnish oxygen which will "prevent organ damage in the brain, heart, lungs, liver and kidneys," until a transfusion can be done at the hospital. - pretty damn cool. I hope it works.
