Different amounts of silk building materials A single H. euryalus cocoon from our sample contained only an outer envelope, i.e., no inner envelope was spun, but the larval pellet and pupal casing were found inside this otherwise normal (size and shape) outer envelope. This cocoon was therefore omitted from our silk analyses. We found that […] More

In this phase I/II single (only participant) blinded pilot trial, we tested safety and efficacy of A. soehngenii in metabolic syndrome subjects and found that daily ingestion of increasing A. soehngenii doses for 1 month was associated with increased fecal levels of A. soehngenii with greatest efficacy in the subjects who received the highest dose.

Field sampling Investigated site was located in Central Siberia, about 15 km west of Krasnoyarsk (N56°01′41.46″; E92°34′39.30″). Samples were collected from five A. sibirica trees exhibiting typical symptoms of the disease. The trees were approximately 30–50 years-old, 6–13 m high, and 8 –14 cm in dbh. The sampling targeted parts of branches and stems representing discrete cankers (Fig. 2A–C). […] More
NEWS FEATURE 27 March 2020 Several cancer and HIV drugs have come from marine organisms, but scientists worry that a new agreement to save species could hinder some research.

Site description and soil property measurements The soil warming experiment was set up at the Kessler Atmospheric and Ecological Field Station in McClain County, OK (34° 59′ N, 96° 31′ W). The mean annual temperature is 16.3 °C and mean annual precipitation is 914 mm [20]. The experiment was a blocked split-plot design and initiated in July, […] More
Study location and field methods We attached either light-level geolocator or Global Positioning System (GPS) tags to adult Swainson’s Thrushes in breeding condition in coastal California, and in the Tahoe and Lassen regions within California’s northern Sierra Nevada and southern Cascade Mountains (hereafter the Cascade-Sierra), in the summers of 2014–2015 (Fig. 1; Supplementary Table S1). Light-level tags […] More
