Being both curious animals and scavengers, polar bears investigate and consume garbage where they come into contact with humans.
After a woman called in Saturday's possible sighting in Friendship, police interviewed the witness at length and decided she was credible and the tip bore investigating, Cerretto said.
We have examined the mitochondrial and nuclear genomes of polar and brown bears to investigate whether polar bears demonstrate lineage-specific signals of molecular adaptation in genes associated with cellular respiration/energy production.
The possible ecological partitioning of these three types of bears was investigated using multi-isotopic tracking of organic (δ13Ccoll, δ15Ncoll) and inorganic (δ13Ccarb, δ18Ocarb, δ18OPO4) fractions of bone.
We explored the distribution of extinct U. spelaeus (cave bear) and three extant bear species U. maritimus (polar bear), U. arctos (brown bear), and U. americanus (black bear) in morphospace, investigating cranial and mandibular shape changes in ontogeny of (U. arctos and U. spelaeus) and adult shape changes among all investigated species.
One to two micrograms of BAC DNA was prepared (as described in Veyrunes et al. 2008) and labelled by nick translation reaction with SpectrumOrange dUTP or SpectrumGreen dUTP (Enzo life Sciences, New York, NY, USA).> -wrap-foot> Frequency of nuclei with a single signal for X-borne loci investigated in this study.
In an earlier review [ 13] I suggested that bringing modern molecular methods to bear to investigate the dynamics of gene expression in the stroma and epithelium at obvious growth and morphogenetic inflection points (eg in front of end buds) would be useful.
And journal editors cannot bear the responsibility of investigating the contributions of every author listed on every paper that comes across their desks.
These issues should be borne in mind when investigating the occurrence of second cancers.
Study respondents reported that in Tanzania, there are only two well-equipped laboratories and the Chief Government Chemist, who bear the responsibility of investigating chemical hazards.
