Self-supervised learning of scale-invariant neural representations of space and time.

Hippocampal representations of space and time seem to share a common coding scheme characterized by neurons with bell-shaped tuning curves called place and time cells. The properties of the tuning curves are consistent with Weber's law, such that, in the absence of visual inputs, width scales with the peak time for time cells and with distance for place cells. Building on earlier computational work, we examined how neurons with such properties can emerge through self-supervised learning.

Wood-loving magic mushrooms from Australia are saprotrophic invaders in the Northern Hemisphere.

Magic mushrooms are fungi that produce psilocybin, an entheogen with long-term cultural use and a breakthrough compound for treatment of mental health disorders. Fungal populations separated by geography are candidates for allopatric speciation, yet species connectivity typically persists because there is minimal divergence at functional parts of mating compatibility genes. We studied whether connectivity is maintained across populations of a widespread species complex of magic mushrooms that has infiltrated the Northern Hemisphere from a hypothesised centre of origin in Australasia.

Ketone monoester ingestion improves cardiac function in adults with type 2 diabetes: a double-blind, placebo controlled, randomised, crossover trial.

Type 2 diabetes (T2D) is a metabolic disease associated with cardiovascular dysfunction. The myocardium preferentially uses ketones over free fatty acids as a more energy efficient substrate. The primary aim was to assess the effects of ketone monoester (K) ingestion on cardiac output index ().

A Small-Molecule Drug for the Self-Checking of Mitophagy.

Mitophagy, particularly in the context of drugs that disrupt mitochondrial membrane potential (MMP), represents a critical focus in pharmacology. However, the discovery and evaluation of MMP-disrupting drugs are often hampered using commercially available marker molecules that target similar or identical zones. These markers can significantly interfere with, obscure, or amplify the functional effects of MMP-targeting drugs, frequently leading to clinical failures.

Case report: Immediate and sustained relief of postherpetic neuralgia with erector spinae nerve block in a 60-year-old woman.

Introduction: The erector spinae plane block (ESPB) is a relatively new regional anesthetic procedure that provides analgesia below the erector spinae muscles in an interfascial plane. The indications for its use continue to expand as we learn more about this block.

Case: We report a case of a 60 year old woman presenting to the emergency department (ED) with severe intractable pain after recent onset of herpes zoster infection.
