A study of Puerto Rico's Africanized honey bees -- which are more docile than other so-called 'killer bees' -- shows they retain most of the genetic traits of their African honey bee ancestors, but that a few regions of their DNA have become more like those of European honey bees. These changes likely contributed to the bees' rapid evolution toward gentleness in Puerto Rico, a change that occurred within 30 years, and could spell hope for beekeeping in North America.
When seeking a cure for a disease, early detection is often the key. The same is true for eliminating invasive species. Identifying their presence in a lake before they are abundant is vital. A recent study successfully used environmental DNA to detect invasive clams in California and Nevada lakes. Researchers believe this tool can help identify pests before they become a problem.
How does the Japanese tree frog figure into the latest work of a noted mathematician? As it turns out, quite prominently. Researchers used the curious mating ritual of male Japanese tree frogs as inspiration for their exploration of 'swarmalators' -- their term for systems in which both synchronization and swarming occur together.
Plant scientists have revealed new insights into the mechanisms that allow certain plants to conserve water and tolerate drought. The research could be used to help produce new crops that can thrive in previously inhospitable, hot and dry regions across the world.
A new study points to yet another human factor that is hampering the ability of fish to reproduce: the timing of our fishing seasons. The study considers how the timing of fishing efforts might disproportionately target certain fish and change the life history patterns of entire populations.
Researchers in physics and mathematics have long used 'preprints' -- preliminary versions of their scientific findings published on internet servers for anyone to read. In 2013, similar services were launched for biology, but following a chance discovery, a scientist and historian has unearthed a long-forgotten experiment in biology preprints that took place in the 1960s.
Scientists working in the vanguard of new genetic technologies have issued a cautionary call to ensure that possible applications in conservation will only affect local populations. Experts have now examined the possible consequences of the accidental spread of existing self-propagating gene drive systems.
European forest managers can have their cake and eat it, because according to a new study maximizing timber production in a forest does not necessarily have to come at a cost of reduced species diversity or the capacity to regulate climate change by the same forest. However most European forests fall well below their possible maximum levels of these three capacities.
Researchers find that the relationship between prairie vole couples suffers when the male has access to alcohol, but his female partner doesn't - similar to what has been observed in human couples. The researchers also found changes in a specific brain region in the male voles. The results could help researchers find strategies to overcome the negative effects of alcohol on human relationships.
Using wide-ranging eDNA analysis combined with traditional collection survey methods, researchers have identified the breeding site of critically endangered fish species Acheilognathus typus in the mainstream of Omono River in Akita Prefecture, Japan.
New research suggests that plant respiration is a larger source of carbon emissions than previously thought, and warns that as the world warms, this may reduce the ability of Earth's land surface to absorb emissions due to fossil fuel burning.
Following the path of radicals and being able to identify many damaged residues because of incredibly accurate, expeditious and sensitive mass spectrometry, three scientists studied the great granddaddy of all photosynthetic organisms -- a strain of cyanobacteria -- to develop the first experimental map of that organism's water world.
A gene that enables resistance to a new devastating strain of stem rust, a fungal disease that is hampering wheat production throughout Africa and Asia and threatening food security worldwide, has been identified by scientists.
