This makes the possibility of living organisms increasingly likely.Boss said he believes human beings will prove that there is life in places other than the earth in his lifetime.“I am 65, ”he told VOA, “But I expect to still be alive when it happens.” Paul Butler works at the ...
Meteorites may be at the heart of many science fiction and disaster films; but when it comes down to real science, Earth is a big planet covered by large, uninhabited areas. When you consider the empty versus occupied planetary surface area, you have pretty low-if-wide-ranging odds--between...
Heterogeneous structures are ubiquitous in natural organisms. Native heterogeneous structures inspire many artificial structures that are playing important roles in modern society, while it is challenging to identify the relevant factors in forming these
The Anthropocene biodiversity crisis is driven by various facets of human activity such as direct exploitation of organisms, transformation of pristine to modified ecosystems, environmental pollution, alteration of the Earth’s climate and human translocation of species beyond their native distributions1,2....
The volume of runoff under the UH, V = 1 cm × A = unit volume, where A is the drainage area. Unit duration: It is defined as the duration over which rainfall intensity is uniform. It is a vital parameter which affects the shape of the UH for the same watershed area (while the ...
we integrate the most up-to-date information on the number of human and bacterial cells in the body. We estimate the total number of bacteria in the 70 kg "reference man" to be 3.8·1013. For human cells, we identify the dominant role of the hematopoietic lineage to the total count (...
Based on microscopic studies, the haploid chromosome number has been variously reported as 40–43 with a diploid number of about 90 and an average molecular weight per chromosome of 4×109 Da (about 6 Mb) (Mohberg, 1977), although there have been reports that the chromosome number varies (...
These factors can influence the distribution, abundance, and behavior of organisms, ultimately affecting the availability and accessibility of specimens for collection (McGill et al., 2006; Vargas et al., 2022). Furthermore, certain studies have observed a phenomenon that specimen collectors and ...
There is evidence that meiotic DSBs localize to different sites in dogs than other mammals [27]; does this cause a different distribution of CNVs in the genome? Is there evidence of fixed CNVs in certain breeds that may lead to breed-specific phenotypes? Can variation at CNV loci be used ...
One of the requirements to perform an analysis of the population structure is the occurrence of genetic variation for some discrete character such as chromosome configurations or isozymal markers. This kind of variation is very often found in organisms such as Drosophila, a genus where t Member ...
