Hydrothermal activity generated by impact melt emplacement on the rim of Ritchey crater, Mars

Nature Communications
Impact-induced hydrothermal systems have the potential to sustain long-lived aqueous environments throughout the history of Mars, yet their nature and distribution are not well-understood.

Crater size estimates for large-body terrestrial impact [PDF]

Calculating the effects of impacts leading to global catastrophes requires knowledge of the impact process at very large size scales. This information cannot be obtained directly but must be inferred from subscale physical simulations, numerical ...

Inhibition of peripheral CB1 receptors modulates food intake and metabolic efficiency in obesity independently of the gut–brain vagal axis

British Journal of Pharmacology, EarlyView.
Background and Purpose Obesity involves profound disruptions in neuronal circuits, neuroendocrine communication and the endocannabinoid system. While global blockade of cannabinoid CB1 receptors improves metabolism, its clinical use is limited by neuropsychiatric side effects.

Melting and its relationship to impact crater morphology [PDF]

Shock-melting features occur on planets at scales that range from micrometers to megameters. It is the objective of this study to determine the extent of thickness, volume geometry of the melt, and relationship with crater morphology.

Terrain Synthesis and Authoring based on Iso‐Contours

Computer Graphics Forum, EarlyView.
Abstract Digital terrains are central to realistic landscape depiction, yet authoring tools must balance perceptual realism with intuitive artistic control. We propose a compact vector‐based representation that models terrain as nested iso‐contours, inspired by geomorphology and cartography.

The Cretaceous-Tertiary (K/T) impact: One or more source craters? [PDF]

The Cretaceous-Tertiary (K/T) boundary is marked by signs of a worldwide catastrophe, marking the demise of more than 50 percent of all living species. Ever since Alvarez et al.

Using incentive payments to promote human–carnivore coexistence

Conservation Biology, EarlyView.
Abstract For many large carnivores, minimizing the financial burden they impose on local people is critical to their conservation. Incentive‐based programs that provide people with financial benefits for taking pro‐conservation actions or achieving conservation goals are a promising tool for promoting human–carnivore coexistence. Although the number of

A history of the Lonar crater, India: An overview [PDF]

The origin of the circular structure at Lonar, India, described variously as cauldron, pit, hollow, depression, and crater, has been a controversial subject since the early nineteenth century.
