There are many levels at which a scientific question can be answered. An answer that is quite satisfying to a scientist from one discipline may be totally unsatisfactory to a scientist from another.

The woolly mammoth lives! At least the hemoglobin in its blood lives, now that researchers have re-created it using a bacteria reprogrammed with 43,000-year-old mammoth DNA. What the now-extinct ...

The tangled mass of tubing, disks and light bulbs unveiled before a packed meeting of the Royal Society of scientists in London looked for all the world like an outsize example of abstract sculpture.

ARLINGTON, Va.– Red-blooded genealogists take note: The discovery in microbes of two oxygen-packing proteins, the earliest known ancestors to hemoglobin, brings scientists closer to identifying the ...

Our ability to breathe oxygen is critical to our survival. This process is mediated by the hemoglobin in our blood, which carries oxygen. Since air contains less oxygen on high mountains, the body is ...

Biomolecules such as hemoglobin or chlorophyll are difficult to study. It is worth investigating similar but simpler structures in the lab. Unexpected behavior has now been found in phthalocyanines, ...

Makio Murayama, a Japanese-American biochemist who was turned away from the Manhattan Project due to his heritage, rose to prominence for his work uncovering the link between the structure of ...

Max Perutz, the British chemist whose efforts to solve the riddle of life by unraveling protein structures led to the creation of the field of molecular biology, died Wednesday of cancer at his home ...

Biochemists in Japan were surprised to discover that the molecule hemoglobin in the blood works not only as an oxygen carrier, but when the blood is spilled as a result of aggression, accident or ...

A new study from North Carolina State University identifies vertebrate hemoglobin in bone extracts from two dinosaurs and shows that this molecule is original to those animals. The work also shows how ...
