Obesity is a widespread health condition1, likely to be driven by the increased availability of inexpensive high-calorie food2. People vary greatly in their behavioural response to food. Such variation is likely to be driven by behavioural styles3,4, as behaviour accounts for overall food intake5. A prominent hypothesis is that people with obesity respond to rewards similarly to people with addictions such as alcohol abuse or smoking6,7. For instance, perceived overeating or ‘uncontrolled eating...

There is a consensus that obesity and addiction are similar, showing overlap in cognition, neural activity and personality traits. A new study using a more nuanced approach for analysing traits reveals how obesity and addiction are less similar than previously thought, while the construct of uncontrolled eating is closely related to addiction.

When an automated car harms someone, who is blamed by those who hear about it? Here we asked human participants to consider hypothetical cases in which a pedestrian was killed by a car operated under shared control of a primary and a secondary driver and to indicate how blame should be allocated. We find that when only one driver makes an error, that driver is blamed more regardless of whether that driver is a machine or a human. However, when both drivers make errors in cases of human–machine s...

Religious restrictions on the scientific teaching of evolution have no place in a balanced society, writes Mohammed Alassiri.
We have known for a while that different doctors can produce different effects using the same substance, or even placebo, such that otherwise effective treatments might become ineffective or placebo becomes effective. Chang and colleagues now clarify that such differential effects are likely transmitted by subtle facial cues, using a placebo–pain model.

Medical treatments typically occur in the context of a social interaction between healthcare providers and patients. Although decades of research have demonstrated that patients’ expectations can dramatically affect treatment outcomes, less is known about the influence of providers’ expectations. Here we systematically manipulated providers’ expectations in a simulated clinical interaction involving administration of thermal pain and found that patients’ subjective experiences of pain were direc...

Human DNA polymorphisms vary across geographic regions, with the most commonly observed variation reflecting distant ancestry differences. Here we investigate the geographic clustering of common genetic variants that influence complex traits in a sample of ~450,000 individuals from Great Britain. Of 33 traits analysed, 21 showed significant geographic clustering at the genetic level after controlling for ancestry, probably reflecting migration driven by socioeconomic status (SES). Alleles associ...
