A 64-year-old man hospitalised for observation after treatment with chimeric antigen receptor (CAR) T-cells targeting the B-cell maturation antigen reported a 4-day history of indentations developing over the top of his head; he had not been involved in any recent trauma and he did not have any pain (figure).

Observing the surface of an exoplanet is tricky, but a study analysing data from the Spitzer space telescope suggests it should be feasible with the more powerful James Webb telescope

Mayor of London also hits out at "vested interests" in motoring lobby backlash against his plans to expand clean air zone to outer London in 2023

Understanding proteins and their complex 3D shapes is key to understanding life, and especially for developing drugs

Nasal vaccines that prevent people from catching the coronavirus may help stem transmission, while universal vaccines could target proteins found in every SARS-CoV-2 variant

An artificial intelligence voice jammer can unobtrusively block microphones recording a single voice in an area, avoiding causing wider disruption that might tip people off

Since 1951, the gap between night and day temperatures has closed by 0.41°C, and simulations show that the bulk of this warming is due to greenhouse gas emissions

Microclots that block blood and oxygen flow are a possible explanation for long covid symptoms like exhaustion and brain fog. Now it seems they may be to blame for chronic fatigue syndrome too

Highly acidic water usually breaks down a tadpole’s gill lining, but an Australian frog has evolved to suck in more protective calcium from the extreme ecosystem where it lives

Penis swelling and rectal pain don't normally occur with monkeypox, but a study of around 200 men in London suggests the symptoms may be common in the latest outbreak

The estimate is thought to be on the low side, because climate models are not doing a good job of reproducing how fast temperatures have risen in western Europe

In The Lancet, Barham K Abu Dayyeh and colleagues present the results of their most recent trial (MERIT),1 assessing the efficacy and safety of endoscopic sleeve gastroplasty (ESG) to treat mild-to-moderate obesity. Abu Dayyeh himself first described ESG in 2013 as a novel transoral gastric plication method.2 The initial technique was based mainly on volume restriction achieved by apposition of the anterior and posterior gastric walls by means of separate interrupted stitches. As ESG diffused worldwide and the understanding of its physiology increased, technical refinements ensued.

ESG is a safe intervention that resulted in significant weight loss, maintained at 104 weeks, with important improvements in metabolic comorbidities. ESG should be considered as a synergistic weight loss intervention for patients with class 1 or class 2 obesity. This trial is registered with ClinicalTrials.gov, NCT03406975.
