Mahi-mahi and marlin appear to split prey-school attacks
Aerial observations suggest the two predators used different parts of mixed feeding groups, but the study does not show that one species caused the other to change.

Active learning maps promising materials for moisture-based carbon capture
Combining laboratory and literature data improved model predictions for resin-based capture, but the study measured equilibrium capacity rather than full operating performance.
Single Neurons in Fly Larvae Differ in Memory Retrieval
Optogenetic tests asked whether the same individual dopamine neurons could support memory-related functions and movement, with two cells showing different retrieval conditions.
NeuroD1 Fails to Turn Mouse Microglia Into Neurons
A peer-reviewed mouse study found that genetically marked microglia kept their original identity instead of becoming neurons, including after brain injury.
South Georgia seabird and mammal pairings fell sharply
A peer-reviewed study found fewer significant species pairings among seabirds and marine mammals, but did not measure individual foraging behaviour directly.
Two Nitrification Inhibitors Show Distinct Effects in a Soil Microbe
A laboratory study found DMPP and ATU were associated with different cellular responses in Nitrososphaera viennensis, but the proposed mechanisms still need direct biochemical testing.
Two triatomine species reported for first time in Oaxaca's Teotitlán District
Researchers identified first local records of T. barberi and T. dimidiata, but the findings do not establish local transmission.
Worm study links pyruvate to an intestinal peptide signal
A peer-reviewed eLife study found that INT1 had a distinct translating-mRNA profile and that pyruvate restored the INS-7 secretion pattern after refeeding under tested conditions.
Gene-edited stem cells linked to multi-organ gains in FRDA mice
A one-time infusion was associated with better movement and tissue measures, but the mouse study did not fully reverse established damage.
Glycan candidate linked to stronger immune-cell activity in lab tests
R3 showed strong interaction with several Siglecs and was associated with higher phagocytosis and cytotoxicity in cell assays, while structural studies of its binding remain underway.
Colombia’s Chagas treatment gap fell, but data remain uneven
An analysis of official records estimated that the share of people needing antiparasitic treatment but not starting it fell from 77.5% to 48.1% between 2012 and 2022.
Gold and titanium dioxide particles form tunable layered structures
Experiments and simulations found that changing the gold-to-rod ratio shifted confined assemblies between membranes and layered smectic structures.
New model maps how small molecules bind disordered proteins
A molecular simulation study estimates binding strength from changing contact paths, while finding that long jumps are uncommon.
Tuberculosis Drug Resistance Linked to a Less Diverse Lung Microbiome
A small study of lung-fluid samples found distinct microbial patterns in drug-sensitive and multidrug-resistant tuberculosis, but the findings need independent validation.
Prenatal PM2.5 Exposure Tied to Higher Autism Risk in Study
An observational cohort found different associations across pregnancy and early childhood, but claims data and zip-code exposure estimates cannot establish cause.
Deeper wells more likely to show high arsenic in Colorado valley
A model of 435 wells found arsenic at or above 5 micrograms per liter in 19.8% of private wells, while a separate analysis estimated county trends from 16,221 wells without arsenic measurements.
Subtype-guided breast cancer treatment shows more complete responses
A peer-reviewed analysis found a higher pathologic complete-response rate, but the biological markers behind the result remain exploratory.
Older Teeth Show Less Root-Canal Sealer Penetration in Lab Study
In extracted teeth, ultrasonic activation and SmartLite Pro EndoActivator performed similarly, while the older donor group showed less penetration near the root tip.
X-ray scans show stronger iron oxide nanoparticle alignment in fields
A laboratory study compared three SAXS methods as the scattering pattern grew more directional, while readings above 118 mT were left out of orientation analysis.
Electrical chip tracks cell migration from single cells to tissues
A label-free capacitance sensor followed individual breast-cancer cells, spreading spheroids and millimetre-scale tissues in laboratory tests.
