Analogues of α-ketoglutarate are used in many cellular studies but assumptions are made about cellular uptake. Here, the authors show that esterified analogues rapidly hydrolyse in aqueous medium resulting in an analogue which can be quickly taken up by many cell lines, contrary to prevailing assumptions.

Sensory experience transforms endogenously structured cortical networks with diverse and unreliable visual responses into reliable representations. This process is proposed to involve the alignment of feedforward and recurrent networks.

The authors use a variety of techniques to isolate and manipulate retinal inputs to direction-selective neurons in the mouse superior colliculus. They show that these cells inherit their selectivity from the retina by combining inputs from similarly tuned ganglion cells, which are further amplified in the colliculus without altering selectivity.

G49, a dual glucagon/glucagon-like peptide-1 receptor agonist, triggers an inter-organ crosstalk between adipose tissue, pancreas and liver, leading to brown fat activation with the final outcomes of increased energy expenditure and body weight loss.

The intracellular applications of STED microscopy are limited by the availability of dyes. Here the authors develop a two-colour labelling strategy based on SiR and ATTO590 dyes, and apply their strategy to image various subcellular membrane compartments.

The authors examined neuronal responses in V1 and V2 to synthetic texture stimuli that replicate higher-order statistical dependencies found in natural images. V2, but not V1, responded differentially to these textures, in both macaque (single neurons) and human (fMRI). Human detection of naturalistic structure in the same images was predicted by V2 responses, suggesting a role for V2 in representing natural image structure.

Materials that can alter their structure in response to light have potential as functional materials such as motors and actuators. Here the authors describe a low-cost system capable of rapid, reversible and wavelength-selective responses to light.

The correction of genetic defects in utero could allow for improved outcomes of gene therapy. Here, the authors demonstrate safe delivery of nanoparticles to fetal mouse tissues, and show that nanoparticles containing peptide nucleic acids to edit the beta-globin gene are effective in a mouse model of beta-thalassemia.

Systematic base-editing and computational screens identify specific cysteine residues on VPS35 in the retromer complex as key sensors that decrease mitochondrial translation in response to reactive oxygen species signals.

Baker et al. show that mitochondrial stress recovery requires mobilization of lipid droplet triacylglycerol stores to facilitate cardiolipin biosynthesis and mitochondrial biogenesis.

Palm recognition faces challenges from variations in palm distance and pose. Here, the authors analyse the impact of distances, determine optimal registration settings, and introduce an edge-aware, rotation-invariant region of interest alignment method that ensures consistent palm region localization.

In a 6-week randomized phase 1 trial, tirzepatide led to reduced caloric intake during a meal test at week 3 compared with placebo and liraglutide in people with overweight or obesity.

Riboswitches are RNA sensors that allow bacteria to sense and respond to their environment. Here, Bushhouse et al. demonstrate that the sensitivity of several riboswitches can be tuned by manipulating how the riboswitch RNAs fold during transcription.

A COVID-19 test implemented in an automated microfluidic device and leveraging isothermal RNA amplification followed by T7 transcription and Cas13-mediated cleavage of a quenched fluorophore rapidly detects SARS-CoV-2 RNA in saliva samples.

Using a single-nucleus multi-omics approach, a study jointly profiles the reorganization of the epigenome and the three-dimensional chromatin conformation during the development of the human hippocampus and prefrontal cortex.

Polyamines are essential metabolites linked to aging, cancer, and Parkinson’s disease. Here, authors develop a live-cell polyamine reporter and use a genome-wide CRISPR screen to uncover a link between mitochondrial respiration and polyamine import.

Post-infectious myalgic encephalomyelitis/chronic fatigue syndrome (PI-ME/CFS) is a disabling disorder, yet the clinical phenotype is poorly defined and the pathophysiology unknown. Here, the authors conduct deep phenotyping of a cohort of PI-ME/CFS patients.

Unseen contents associated with null perceptual sensitivity can be reliably decoded from brain activity in higher-order areas in single human observers. This result was reproduced in deep artificial neural networks performing a similar visual task.
