Ashwagandha: Is It Safe? Part 1: A Regulatory Review

open access: yesPhytotherapy Research, EarlyView.
ABSTRACT Over the last decade, ashwagandha (Withania somnifera (L.) Dunal, AS) has been brought under increasing scrutiny by EU regulators regarding its safety for the use in food supplements, culminating in a recent recommendation for an Article 8 procedure according to Regulation (EC) No. 1925/2006 in the European Union (EU).

Evaluation of Potential Hormonal Activities of Ashwagandha (Withania somnifera)

open access: yesPhytotherapy Research, EarlyView.
ABSTRACT Ashwagandha is a widely used herb in traditional medicine systems, particularly Ayurveda. Despite its extensive tradition, growing concerns regarding its potential endocrinological effects have prompted scientific scrutiny. This review systematically evaluates the current preclinical, clinical, and case study evidence concerning AS's effects ...

Seasonal and diurnal groundwater fluctuations linked to environmental and drought variability for the Kermit dune field, Chihuahuan Desert, West Texas, United States

open access: yesFrontiers in Earth Science
Water availability is limited in the northern Chihuahua Desert due to increasing aridity and anthropogenic disturbance. This study investigates the groundwater fluctuations in the shallow water table of the Kermit dune field, West Texas, United States ...

Thermodynamic and microphysical properties of summertime marine fog observed from Sable Island

open access: yesQuarterly Journal of the Royal Meteorological Society, EarlyView.
Atmospheric profiling and near‐surface fog and visibility measurements revealed synoptic‐scale forcing as the dominant factor in fog formation over Sable Island, with deep fog layers under low‐pressure systems and shallow fog layers under high‐pressure systems.

A new method to identify and explain sources of precipitation modification, illustrated for the western Netherlands

open access: yesQuarterly Journal of the Royal Meteorological Society, EarlyView.
This study develops a method to identify the source areas of precipitation events, as illustrated for the western part of the Netherlands. Radar‐based precipitation data are traced back to their source areas and machine‐learning techniques are used to identify hypothesized causes: urban heat, surface roughness, and air pollution. We find that urban and

Terrain Classification for Planetary Rovers Using Wireless In‐Wheel Sensor Modules and Machine Learning

open access: yesJournal of Field Robotics, EarlyView.
ABSTRACT Safe and reliable mobility over different kinds of ground is important for planetary rovers on space missions. Since terrain changes might affect the mobility of the rover, energy consumption, and safety, detecting the type of ground in real‐time is vital.

Dunes and Drumlins

open access: yes, 2001
Dunes are landforms which occur when a turbulent fluid flow occurs above an erodible substrate. The most obvious example occurs in deserts, where the wind blows sand into a wide variety of different shapes (see Chap. 17 for many illustration of such dunes). Linear dunes, or ‘seifs’, are ridges which form parallel to the prevailing wind direction, while

Timing of frost deposition on Martian dunes: A clue to properties of dune particles? [PDF]

open access: yes
Scans were made across the Martian dunes found in images taken at several different times to determine the time history of the dune albedo. Atmospheric contributions were estimated using optical depth data and the brightness of shadows in some images ...

Breaking down seagrass fragmentation in a marine heatwave impacted World Heritage Area

open access: yesRemote Sensing in Ecology and Conservation, EarlyView.
Habitat fragmentation can exacerbate the impacts of habitat loss but is rarely quantified in marine environments. Using satellite‐derived habitat maps, we identify widespread seagrass fragmentation following a marine heatwave that contributed to a dramatic shift in seascape structure in the Shark Bay World Heritage Area.
