The first major study into the impact of inshore potting for crab and lobster within a Marine Protected Area has found that in areas of low potting intensity the industry is operating in a way that had little impact on seabed species or economically-important shellfish.
A national study finds differences in the decisions to admit or transfer children with mental health emergencies based on the patients' insurance type. Children without insurance are more likely to be transferred to another hospital than those with insurance.
A new study finds that different bird species in the same challenging environment -- the highly saline ecosystem of tidal marshes along ocean shores -- were able to evolve unique species-specific ways to address the same problem.
Researchers have created a device that can determine whether targeted chemotherapy drugs are working on individual cancer patients. The portable device, which uses artificial intelligence and biosensors, is up to 95.9% accurate in counting live cancer cells when they pass through electrodes, according to a new study.
Physicists have theorized that a new type of material, called a three-dimensional (3-D) topological insulator (TI), could be a candidate to create qubits for quantum computing due to its special properties. A study found that when the TI's insulating layers are as thin as 16 quintuple atomic layers across, the top and bottom metallic surfaces begin to destroy their metallic properties.
A new study describes how researchers wirelessly controlled FGFR1 -- a gene that plays a key role in how humans grow from embryos to adults -- in lab-grown brain tissue. The ability to manipulate the gene, the study's authors say, could lead to new cancer treatments, and ways to prevent and treat mental disorders such as schizophrenia.
The first direct measurement of the bar-shaped collection of stars at the centre of our Milky Way galaxy has been made by combining data from the Gaia mission with complementary observations by ground- and space-based telescopes.
When it comes to mating displays, a little persistence can go a long way, at least for the greater sage grouse. Scientists have now used a custom-built statistical model to understand an underexplored dimension of greater sage grouse mating display behavior. The authors report that males that show greater display persistence, even in the face of seemingly uninterested females, have a competitive advantage over their peers.
Floating air particles following disasters and other geological events can have a lasting impact on life on Earth, and a new model drawing on chaos theory looks to help predict how these particles move, with an eye toward applications for geoengineering. Scientists have developed a model for following particles as they travel around the globe. Using it, she has generated maps that can be used to predict how particles will be dispersed above the world.
Nucleotide-binding, leucine-rich repeat receptors (NLRs) perceive pathogen effectors to trigger plant immunity. Biochemical mechanisms underlying plant NLR activation have until now remained poorly understood. We reconstituted an active complex containing the Arabidopsis coiled-coil NLR ZAR1, the pseudokinase RKS1, uridylated protein kinase PBL2, and 2'-deoxyadenosine 5'-triphosphate (dATP), demonstrating the oligomerization of the complex during immune activation. The cryo-electron microscopy structure reveals a wheel-like pentameric ZAR1 resistosome. Besides the nucleotide-binding domain, the coiled-coil domain of ZAR1 also contributes to resistosome pentamerization by forming an α-helical barrel that interacts with the leucine-rich repeat and winged-helix domains. Structural remodeling and fold switching during activation release the very N-terminal amphipathic α helix of ZAR1 to form a funnel-shaped structure that is required for the plasma membrane association, cell death triggering, and disease resistance, offering clues to the biochemical function of a plant resistosome.
