Efforts to achieve net-zero carbon emissions from transportation fuels are increasing demand for oil produced by nonfood crops. These plants use sunlight to power the conversion of atmospheric carbon dioxide into oil, which ...
Our personalities are generally thought to consist of five primary factors: openness to experience, conscientiousness, extroversion, agreeableness and neuroticism, with each of us ranking low to high for each.
The awe-inspiring process of cell division can turn a fertilized egg into a baby—or a cancerous cell into a malignant tumor. With so much at stake, nature keeps it tightly controlled in a process called the cell cycle that ...
There are eight species of baobab in the world, and they have a surprising distribution. Six are found in Madagascar, an island in the Indian Ocean; one is found on the continent of Africa; and the last is far away in Australia.
What establishes the male or female sex of an ant? In humans, it is X and Y chromosomes that assume this function: Women have two X chromosomes while men have one X and one Y chromosome. In ants, bees, and wasps, the factor ...
Researchers from the Leibniz Institute of Freshwater Ecology and Inland Fisheries (IGB) and the National University of Singapore have identified a gene locus responsible for sex determination in the European green toad. This ...
In Hungary, ethological research is most often identified with tests on dogs, but novel methodological advances could bring another species, the paradise fish, into the spotlight. Fish are easy to handle and produce numerous ...
Chromosomal inversions are structural variations that play a significant role in suppressing genetic recombination, thereby fixing favorable allelic combinations. These inversions are crucial for maintaining coadapted genotypes ...
The human genome contains about 23,000 genes, but only a fraction of those genes are turned on inside a cell at any given time. The complex network of regulatory elements that controls gene expression includes regions of ...
The length of telomeres that protect the ends of our chromosomes should be tightly regulated. Those that are too long predispose to cancer, and those that are too short lose their protective ability, resulting in telomere ...
