The collision between two high-speed trains in Adamuz (Córdoba) on Sunday afternoon has left at least 39 people dead and more than a hundred injured. The emotional impact of the accident affects the families of the victims, as well as the crash survivors and other train users.
One in five people in Spain suffers from unwanted loneliness, but what exactly is it? What consequences can it have and who suffers from it most? Is it appropriate and realistic to talk about an epidemic of loneliness? What are the causes and possible solutions? What role do social networks play? We answer these and other questions about a central problem in our societies.
Until now, perceived well-being followed a U-shaped curve depending on age, declining – due to worry, stress or depression – until people reached middle age, around 50, and then rebounding into old age. With malaise, the U is inverted and we talk about the ‘unhappiness curve’, shaped like a hump. Now, research published in PLOS One with data from the US and the UK claims that this age-related malaise is declining and that there is no longer such a hump. The reason for the change is said to be the deterioration of mental health among young people, especially those under 25. The study also includes data from 44 countries between 2020 and 2025, including Spain, and confirms that the malaise no longer takes the form of a hump, but decreases with age.
From 2014 to 2023, one in six people in the world suffered from loneliness, according to a World Health Organisation report, which outlines the causes of this phenomenon and its multiple impacts: on physical and mental health and mortality, as well as on work and the economy. The report estimates that loneliness is linked to more than 871,000 deaths per year and highlights a higher incidence among young people and in low- and middle-income countries.
The number of adolescents with anxiety problems seems to be increasing, especially in developed countries. An opinion article published in the journal Science proposes that maternal stress, quality of care and environmental conditions in the early years, together with current social and technological changes, may contribute to explaining this trend.
Research involving more than 200 patients with depression, whose symptoms had not improved after NHS talk therapy shows that those who took part in eight group sessions of mindfulness-based cognitive therapy saw their depressive symptoms reduced, compared with those who received treatment as usual. The study is published in The Lancet Psychiatry.
The frequency of aggressive coalitions among female bonobos is associated with greater power over males, according to a study published in Communications Biology. The analysis is based on observations of six wild bonobo communities in the Democratic Republic of Congo between 1993 and 2021.
People who grow up with more brothers or sisters may have a more cooperative personality, i.e. with traits such as honesty, humility and agreeableness, according to a study published in PNAS. Using data from 700,000 adults surveyed online, the research concludes that mean honesty-humility and agreeableness scores are slightly higher in people with more siblings. Among those with the same number of siblings, people born middle and last have a slightly higher mean score than firstborns.
Unmarried people - whether single, divorced/separated or widowed - have a higher risk of having depressive symptoms than married people, says an international study. The paper, published in Nature Human Behaviour, includes data from more than 100,000 adults in China, Indonesia, Ireland, Korea, Mexico, the UK, the USA and the UK.
Chronic pain is a public health problem that affects almost one in six people in Spain, with very different origins and characteristics. Specialists in psychology and pain explain what it is, how it is treated, what consequences it has for those who suffer from it and how to learn to live with it.
