When science hits the headlines, we seek the views of expert sources who assess the news rigorously and quickly, according to the available evidence.
A study published in the journal Nature Communications in mice has associated the inhalation of e-cigarette aerosols with heart rhythm disorders, including ventricular arrhythmias.
The IceCube collaboration, with its detector located under the Antarctic ice sheet, has used astrophysical neutrinos to search for changes in the structure of space-time. In the research, published in Nature Physics, the team analysed more than seven years of data and found no signs of a modified structure of space-time imprinted in the characteristics of these particles, a further step towards understanding quantum gravity.
On Thursday, president Pedro Sánchez announced an agreement with France and Portugal to create the "green energy corridor", which will connect Spain, Portugal and France to the European Union's energy network. According to the government, the corridor envisages the creation of a maritime gas pipeline connecting Barcelona with Marseille, which will be used to transport natural gas, hydrogen and other gases.
A study published in The Lancet Child & Adolescent Health shows that 98% of a cohort of trans adolescents in the Netherlands who started hormone treatment before adolescence continued to do so years later.
Research published in Science concludes that mice that feed at night - the active phase of their daily circadian cycle - burn more calories, mitigating the development of obesity.
A meta-analysis published in the journal PLOS Medicine has analysed the time to diagnosis and treatment of various types of cancer in rich and poor countries. On average, the processes are 1.5 to 4 times slower in disadvantaged countries.
A double clinical trial has analyzed the efficacy of ruxolitinib cream in treating depigmentation associated with vitiligo. The results are published in the New England Journal of Medicine.
A study in mice published in the journal Nature has analysed the different responses to aggression and the consequences for subsequent behaviour. In general, animals that confronted the aggressor developed greater resilience than those that fled or avoided the aggressor, and the gain was greater as brain circuits associated with dopamine were activated.
Research published in Nature Human Behaviour analyses changes in life expectancy since the advent of covid-19. Its findings show that some countries in western Europe, including Spain, regained some of their lost life expectancy, and others returned to 2019 levels. On the other hand, losses continued in Eastern Europe and the United States.
The Committee for Medicinal Products for Human Use (CHMP) of the European Medicines Agency (EMA) has recommended granting marketing authorisation for the tetravalent dengue vaccine (live, attenuated) Takeda. The vaccine is intended to prevent disease caused by dengue virus serotypes 1, 2, 3 and 4 in people aged four years and older. Although an approved vaccine already exists, according to the EMA, this quadrivalent vaccine shows increased protection in children and people over 45 years of age.
