NOAA has published a peer-reviewed State of the Monument report that was jointly produced by the co-trustees of Papahānaumokuākea Marine National Monument. The report includes information on the status and trends of living resources, habitats, ocean conditions, maritime and cultural archaeological resources, and the human activities and natural events that affect them.
Since the 1950s, "Africanized" honeybees have spread north and south across the Americas until apparently coming to a halt in California and northern Argentina. Now genome sequencing of hundreds of bees from the northern and southern limits shows a gradual decline in African ancestry across hundreds of miles, rather than an abrupt shift.
Cucurbit downy mildew is a devastating disease affecting economically important crops such as cucumber, cantaloupe, squash, pumpkins, and watermelon. Previously effective fungicide have been failing in the United States and Europe, making accurate and early diagnosis critical for timely disease management.
A study published in Cell Reports shows how next generation genetic sequencing can track mutations in the SARS-CoV-2 virus, which can in effect help with transmission tracing, diagnostic testing accuracy and vaccine effectiveness.
Climate change pushes species distribution areas northward. However, the expansion of species ranges is not self-evident due to e.g. habitat degradation and unsustainable harvesting caused by human activities. A new study led from the University of Turku, Finland, suggests that protected areas can facilitate wintering waterbird adaptation to climate warming by advancing their range shifts towards north.
How life works may come down to dumbbell-like bits of DNA.
The capacity for language is built upon our ability to understand combinations of words and the relationships between them, but the evolutionary history of this ability is little understood. Now, researchers from the University of Warwick have managed to date this capacity to at least 30-40 million years ago, the last common ancestor of monkeys, apes and humans.
Releasing captive-bred Atlantic salmon into the ocean, a long-standing practice to boost stocks for commercial fishing, reduces the rate at which wild populations reproduce and may ultimately do more harm than good, researchers cautioned Wednesday.
Environmental groups asked a federal court Wednesday to throw out the Trump administration's assessment of oil and gas activity's likely effects on endangered species in the Gulf of Mexico, saying it dismisses the chance of another disastrous blowout like the BP spill of 2010.
The newly published thesis research of University of Guam Master of Environmental Science graduate Benjamin Deloso now adds to the body of knowledge about asexual propagation of the most endangered plant group in the world, cycads. His work was part of a set of UOG studies, all focused on improving the asexual propagation of cycads, published in the September 2020 issue of HortScience, one of the oldest horticultural journals in the United States.
During cell division specific target proteins have to be turned over in a precisely regulated manner. To this end specialized enzymes label the target proteins with signaling molecules. However, the enzymes involved in this process can also label themselves, thus initiating their own degradation. In a multidisciplinary approach, researchers identified a mechanism of how enzymes can protect themselves from such self-destruction and maintain sufficient concentrations in the cell. These results have been published in the latest issue of Science Signaling.
We employ our cognitive skills daily to assimilate and process information. A new empirical study shows that we do better at this task than those born a century ago. But cognitive capacity still begins to stagnate at around the age of 35.
Marine fish species are migratory in nature and not respectful of human-made territorial boundaries, which represents a challenge for fisheries management as policies tend to focus at the national level. With an average catch of 48 million tons per year, and USD $77 billion in annual fishing revenue, these species support critical fisheries, and require international cooperation to manage, according to UBC research.
In research, the results of studies must be precise and reproducible. For this reason, researchers carry out experiments under strictly standardized laboratory conditions. However, despite the high standards applied, results from individual studies cannot always be reproduced in practice. Especially in cases in which animals are used for research purposes and the original study cannot be repeated, this raises severe ethical questions. For a long time now, researchers have been debating this aspect under the heading 'reproducibility crisis.' Behavioral scientists at the University of Münster have now been able to demonstrate that a new experimental design can improve the reproducibility and validity of results from studies involving animal experiments. The study has been published in the journal Scientific Reports.
Transcription factor proteins are the light switches of the human genome. By binding to DNA, they help turn genes 'on' or 'off' and start the important process of copying DNA into an RNA template that acts as a blueprint for a new protein.
France's highest appeals court rejected Wednesday a Monsanto bid to overturn a ruling against it in a suit brought by farmer Paul Francois, who was intoxicated by the firm's weed-killer Lasso.
Indian dairy farmers will be able to trial a new portable testing kit that can help target antibiotics to treat cows and buffalo, and tackle the global threat of antimicrobial resistance (AMR).
The best of eastern and western blackberry genetics have been melded to create Eclipse, Galaxy and Twilight, three new blackberry varieties released by the Agricultural Research Service (ARS).
In a world first, New Zealand researchers have sequenced the genome of three wasps, two of which are invasive wasps in New Zealand, paving the way for new methods of control for these significant pests.
The two key molecules that interact to drive fungal sepsis and meningitis are IP7—a molecule essential for fungal cell metabolism, and the protein Pho81—which regulates intake of the essential nutrient, phosphate.
