Blood Discovery: New Hemoglobin Type Found

ScienceDaily (Mar. 17, 2008) — Scientists at the University of Bonn have discovered a new rare type of haemoglobin. Haemoglobin transports oxygen in the red blood corpuscles. When bound to oxygen it changes colour. The new haemoglobin type appears optically to be transporting little oxygen. Measurements of the blood oxygen level therefore present a similar picture to patients suffering from an inherited cardiac defect. After examining two patients, the scientists now understand that the new type of haemoglobin distorts the level of oxygen measured.

Powerful Stellar Explosion: An Action Replay


ScienceDaily (Mar. 20, 2008) — Astronomers have made the best ever determination of the power of a supernova explosion that was visible from Earth long ago. By observing the remnant of a supernova and a light echo from the initial outburst, they have established the validity of a powerful new method for studying supernovas.

Mars, Earth And Moon From 'Unique Planetary Nursery'

ScienceDaily (Mar. 20, 2008) — A study of meteorites suggests that Mars, the Earth and the Moon share a common composition from ‘growing up’ in a unique planetary nursery in the inner solar system.The finding could lead to a rethink of how the inner solar system formed.

In the journal Nature the international team of scientists, which includes Professor Alex Halliday from Oxford University’s Department of Earth Sciences, report how they analysed 16 meteorites that fell to Earth from Mars. They found that the amounts of neodymium-142 these contain are subtly different from those of objects found in the asteroid belt. This isotopic fingerprint is proof that the chemistry of the inner solar system was different even for elements that are hard to vapourise.
