Michigan State scientists identify chemical come-on of sea lamprey
...er to about 30 milligrams of pure compound. Their painstaking methods included creating bioassays to trace the key chemicals and sorting compounds by washing these compounds through a lamprey's nose and tracking its neurological - called electro-olfactogram - and behavioral responses.

...235 for primates, now thought to be a minimum). A painstaking review of the scientific literature revealed a total of 474 recorded fossil primate species. Applying the new approach to the data divided into stratigraphic intervals indicated that there were 8,000-9,000 extinct primate species. Broad implications...UCSF finding offers provocative insight into what drives cancer

Members of the research team reviewed each patients medical record for a complete understanding of the clinical data. They then ...Genetic studies shed light on the malaria parasite's origins and drug resistance
...hey could detect any nucleotide differences. This painstaking process revealed great diversity in the five genomes. Based on these differences, the scientists estimate the earliest common parasite ancestor must be 100,000 to 180,000 years old, a timeframe coincident with human population expansion out of Afric...UK scientists crack lobster shell colour puzzle

Nicotine changes to nornicotine when tobacco is "senescing" - getting old and turning yellow - so genes involved in the aging process are getting a close look. They also suspect that the chrom...Caught sleeping: Study captures virus dormant in human cells
... to the study's success, said Shenk, was Goodrum's painstaking work in learning to handle freshly harvested bone marrow cells in the lab and to maintain them in a state that matches as closely as possible their condition in the human body. Her supply of cells was limited because they are badly needed for bone ma...Stung by success: Intensive farming may suppress pollinating bees

They then removed the bags, put the freshly opened flowers on the ends of sticks and presented them in front of bees to ...New life discovered in deep ocean floor
