NOAA report reveals condition of natural and cultural resources of Papahānaumokuākea

10 hours 3 minutes ago
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.

Genome sequencing shows climate barrier to spread of Africanized bees

10 hours 11 minutes ago
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.

Protected areas help waterbirds adapt to climate change

10 hours 44 minutes ago
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.

Building blocks of language evolved 30-40 million years ago

12 hours 18 minutes ago
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.

Suit: Feds ignore risk of huge spills to endangered species

12 hours 55 minutes ago
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.

Study finds go-to hormone for cycad propagation ineffective

13 hours 16 minutes ago
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.

In cell division, it's all about the right balance

14 hours 2 minutes ago
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.

Management of exploited transboundary fish stocks requires international cooperation

15 hours 5 minutes ago
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.

Animal-based research: New experimental design for improved reproducibility

15 hours 8 minutes ago
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.
