New research has found that clinical animal behaviorists should focus on helping dog owners to feel confident in the effectiveness of the behavior modification techniques that they recommend and, in their ability, to actually use them successfully.

Dinoflagellate plankton glow so that their predators won't eat them

Monday June 17th, 2019 03:05:38 PM
Some dinoflagellate plankton species are bioluminescent, with a remarkable ability to produce light to make themselves and the water they swim in glow. Now, researchers have found that for one dinoflagellate species (Lingulodinium polyedra), this bioluminescence is also a defense mechanism that helps them ward off the copepod grazers that would like to eat them.

Cell biology: Preventing drugs from being transported out of the cell

Monday June 17th, 2019 02:41:23 PM
A research team has investigated the transport mechanism of a bacterial membrane protein using an artificially produced antibody fragment. The transport proteins, called ABC exporters, are present, for instance, in the cell membranes of bacteria and in large quantities in cancer cells and are responsible for transporting small molecules out of the cells. Some transporters can pump antibiotics or chemotherapy agents out of the cells, thus rendering therapies ineffective. In the current study, researchers showed how the transport mechanism can be blocked.

Schizophrenia: Adolescence is the game-changer

Monday June 17th, 2019 02:09:53 PM
Schizophrenia may be related to the deletion syndrome. However, not everyone who has the syndrome necessarily develops psychotic symptoms. What triggers the illness? Researchers (UNIGE) have provided an initial answer after analysing several years of patients with deletion syndrome. They found that the size of the hippocampus was smaller than normal but followed the same developmental curve as in healthy subjects. Yet, when the first psychotic symptoms appear - generally in adolescence - the hippocampus atrophies dramatically.

Race, ethnicity and exclusionary discipline practices

Monday June 17th, 2019 02:09:48 PM
Discipline and how it is administered in schools across the US continues to be a hotly debated topic. A new project analyzed how ethnicity and race are associated with school exclusionary discipline practices, which refer to students being removed from school as a form of punishment. Previous studies have found ethnic and racial disparities in the rates of school discipline actions, where ethnic and racial minority students (particularly African American youth) were found to be overrepresented among students that are disciplined.

CJD is a fatal neurodegenerative brain disease of humans believed to be caused by infectious prion protein. The researchers hope the human organoid model will enable them to evaluate potential CJD therapeutics and provide greater detail about human prion disease subtypes.

No evidence for increased egg predation in the Arctic

Friday June 14th, 2019 03:19:31 PM
Climate and ecosystems are changing, but predation on shorebird nests has changed little across the globe over the past 60 years, finds an international team of 60 researchers. The study published in Science on 14 June 2019 challenges a recent claim that shorebird eggs are more often eaten by predators due to climate change, and more so in the Arctic compared to the tropics. The research shows that these claims are a methodological artefact.
