A study published in the BMJ looks at the risk of thromboembolic events associated with different covid-19 vaccines, both adenovirus- and mRNA-based. Its results are based on data collected from more than 10 million adults in France, Germany, the Netherlands, Spain, the UK and the US who received at least one dose of a covid-19 vaccine from December 2020 to mid-2021.

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 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.
