...ps in a refrigerator, Tibbetts used a toothpick to apply Testor's model paint to their faces. Some wasps were given blotchier faces, some wasps had blotches covered up, and some wasps were just handled and had paint put on their existing blotches.

Kidneys came from 74 patients, ranging in age from 27 to 92. Samples were extracted from donated kidneys or "meticu...Researchers reconstruct parts of the genome of a common mammalian ancestor
... These observations apply both to the DNA regions that code for proteins and to other parts of the genome. In addition to the approximately 1.5 percent of the human genome that codes for proteins, several percent more has been strongly conserved and must be playing some role ...Computer analysis shows scientists could reconstruct the genome of the mammalian common ancestor
... it was 98 percent accurate. The next step was to apply the reconstruction process to the actual genomic sequences for the CFTR locus in the 19 mammalian species for which this DNA sequence was available, including humans. The researchers evaluated the accuracy of this reconstruction by comparing it to sp...Science and medicine - bridging the gap

The work may apply to humans, he said, because taking rewards without hesitation may have paid off for our foraging ancestors, as it does for blue jays and other foragers.
