Journalists

Covering current events in science, the environment, technology and health requires a context and reliable sources that respond quickly.

¿Qué me ofrece?

When science hits the headlines, we publish reactions, explanations, and in-depth analysis from reliable sources, capturing both the evidence and the debates. Our library of science journalism resources and the briefings may be of use to you. Consult our directory of research centres.

Reaction: IceCube detects for the first time the emission of high-energy neutrinos from inside the Milky Way galaxy

The IceCube neutrino observatory, built deep under Antarctic ice, has detected the emission of high-energy neutrinos from within the Milky Way. According to the research, published in the journal Science, this is the first time scientists have obtained solid evidence for the emission of these particles within our galaxy, as they had previously identified high-energy neutrino emission from extragalactic sources.

Reactions: evidence found of a cosmic background of gravitational waves possibly produced by supermassive black hole collisions

The International Pulsar Timing Array (IPTA) consortium has discovered evidence for the existence of a cosmic background of gravitational waves. The results, published by different IPTA consortia in several scientific journals, would show that this cosmic background would be the result of collisions of supermassive black holes. In 2015, researchers from the LIGO and Virgo collaborations made the first direct observation of gravitational waves caused by the collision of two stellar-mass black holes. These waves oscillate several times per second. What the consortia have now found are gravitational waves emitted by supermassive binary black holes at the centre of galaxies, waves that oscillate on timescales of many years.

Reactions: study associates hormone therapy for menopause with possible development of dementia

The use of hormonal replacement therapy (HRT) for menopause is associated with the development of dementia and Alzheimer's disease, even for short prescriptions before the age of 55, according to an analysis of data from the Danish national registry published in The BMJ. The research - which observes associations and cannot determine causality - also shows that the use of progesterone alone and vaginal oestrogen are not associated with the development of dementia.

Reactions: exposure to urban green spaces is associated with slower epigenetic ageing

Living near green spaces over a long period of time is associated with better health, an association more marked in women and white people than in men and black people, according to a study conducted in four US cities. The analysis concludes that exposure to urban green space between 1985 and 2006 is associated with slower epigenetic ageing, and that this association is stronger in disadvantaged neighbourhoods. The international team publishing this paper in Science Advances includes a researcher from ISGlobal in Barcelona.

Reaction: Under-the-skin implant tested to prevent HIV infection in non-human primates

Pre-exposure prophylaxis (PrEP), which usually consists of taking a daily oral anti-HIV drug, is a highly effective measure to prevent HIV infection. However, it only works well if people strictly follow the protocol, and some people end up not adhering to it. To improve this situation, researchers have tested an implant under the skin of non-human primates that releases the antiretroviral drug islatravir and maintains adequate concentrations for at least 20 months. The results, published in the journal Science Translational Medicine, show complete protection against infection with repeated exposure.

Reactions: climate change will increase extreme rainfall and decrease snowfall events

A study concludes that climate change will lead to less precipitation in the form of snow and more extreme rainfall events, especially at high altitudes in the northern hemisphere, increasing the risk of floods, landslides and infrastructure damage. According to the authors, this is the first time this risk of extreme precipitation in liquid and solid form has been studied separately. Their calculations indicate that for each degree of temperature increase, the risk of extreme rainfall in high-altitude regions will increase by 15 %. The authors publish their results in the journal Nature.

Reaction: First genetic variant associated with severity of multiple sclerosis identified

An international team, involving researchers from Hospital Clínic-IDIBAPS and the Multiple Sclerosis Centre of Catalonia (Cemcat), has identified for the first time a genetic variant related to the progression of multiple sclerosis. It is located near two genes that had not previously been linked to multiple sclerosis. According to Stephen Sawcer, co-lead author of the study, "understanding how the variant exerts its effects on the severity of multiple sclerosis will pave the way for a new generation of treatments that can prevent disease progression". The results are published in the journal Nature.

Reactions: a protein is identified that prevents transmission and replication of avian influenza viruses in humans

Although outbreaks of H5N1 avian influenza have reached record numbers in recent years, human infections remain anecdotal. A study published today in Nature identifies a protein responsible for inhibiting the replication of this virus in humans, while 'human' flus are able to evade it. The authors propose that this protein with antiviral activity evolved in primates and consider that resistance or sensitivity to it should be taken into account when assessing the zoonotic potential of avian influenza viruses.

Reaction: ‘Nature’ journal publishes two models that mimic human embryo development after implantation in the womb

Berna Sozen's lab at Yale University has announced a new milestone in the competition to create synthetic embryos: their human pluripotent stem cells self-organise into structures that mimic embryonic development on days 9-14 after fertilisation and include extra-embryonic tissues. Their achievement is published in Nature at the same time as another similar study, that of Magdalena Zernicka-Goetz, who a fortnight ago previewed her stem cell-derived human embryo model to The Guardian, sparking a controversy with Jacob Hanna, author of a preprint showing that she had achieved true synthetic embryos.
