A publication in the journal AIP Advances reports the detection over the tropics of a large ozone hole, defined as an area where more than 25% of the usual ozone has been lost. The hole would be comparable in depth to the well-known hole over Antarctica, but would cover an area seven times larger.

A study published in Nature Geoscience shows how climate change is interfering with processes affecting atmospheric circulation and significantly altering the climate in Spain and Portugal. The anomalous expansion of the Azores anticyclone is drying out the Iberian Peninsula and making it increasingly resemble North Africa.

Ukrainian mathematician Maryna Viazovska was today awarded one of four Fields Medals, considered the Nobel Prize in mathematics. After Iran's Maryam Mirzakhan, who received it in 2014, she is the second woman to be honoured with this prestigious award.

This week we celebrate not only the tenth anniversary of the discovery of the Higgs, but also Run 3: the Large Hadron Collider is back on line to collect a huge amount of data that opens the door to the discovery of new phenomena that could solve unsolved mysteries, such as understanding what makes up the dark matter that makes up 25% of the universe.

The first study of UK cases of the current monkeypox outbreak finds differences between the symptoms of these patients and those of previous outbreaks in other parts of the world. The work is published in the journal The Lancet Infectious Diseases.

On 4 July 2012, physicists from all over the world celebrated the milestone achieved by CERN's Large Hadron Collider (LHC) in Geneva: they had found the elusive Higgs boson, described theoretically in 1964 and a key part of the standard model. Among the dozens of scientists who participated in that discovery, with the ATLAS and CMS experiments, there were many Spanish physicists, who ten years later appreciate what it meant.

The rise in cases of asthma, allergies and digestive tract diseases, among others, could be linked to changes in the microbiome. US researchers are propose to combat this trend by having us all save samples of our own gut microbiota when we are young and healthy, for later use in an autologous faecal microbiota transplant.

Communicating outbreaks of infectious diseases is not easy, especially when they affect population groups that may face discrimination. Cases of monkeypox among men who have sex with men remind us of the importance of reporting without stigma.

Lamivudine, a commonly used antiretroviral drug for the treatment of HIV, improves cognitive ability in a mouse model of Down's syndrome, according to a new study published today in the Journal of Cellular and Molecular Medicine.
