Reactions to planting trees in drylands to fight climate change

A study published in Science analyses the potential climate benefits of afforestation - both planting trees to create new forests and reforesting old ones - of the world's drylands. The authors show that the cooling effect of afforestation of this vast area would only amount to a decrease of about 1 % of projected greenhouse gas emissions in the business-as-usual and medium-emissions climate scenarios.

Reaction to clinical trial testing treatment for a form of ALS

The New England Journal of Medicine reports the publication of data from a clinical trial studying the drug Tofersen against a form of Amyotrophic Lateral Sclerosis (ALS) caused by mutations in the SOD1 gene, which accounts for 2% of sporadic ALS. Six months after treatment, some biomarkers of neuronal damage improved, but not the clinical condition of the patients. In an extension of the study, with no placebo group, a slowing of functional loss was observed, although the researchers acknowledge that there are limitations in interpreting this result.

Reaction: Study finds high levels of PFAS in school uniforms sold in North America

Researchers have analysed the presence of perfluoroalkyl and polyfluoroalkyl substances (PFASs) in 72 textile products purchased online in the US and Canada in 2020 and 2021. The results, published in the journal Environmental Science and Technology Letters, show high concentrations in school uniforms and higher concentrations in 100 % cotton as opposed to synthetics.

Reaction: up to two thirds of urban tree species withstand climatic risk conditions

International research on more than 3,000 tree and shrub species in 164 cities -including Barcelona, Valencia and Santa Cruz de Tenerife- reveals that up to two-thirds of urban tree species may already be experiencing climatic conditions that exceed their potential climate tolerance. The study is published in Nature Climate Change.

Reaction: EMA recommends approval of a new respiratory syncytial virus (RSV) drug for babies and infants

The European Medicines Agency (EMA) has recommended marketing authorisation in the European Union for Beyfortus (nirsevimab) to prevent respiratory syncytial virus (RSV) lower respiratory tract disease in babies and infants. The agency recommends it during its first RSV season. The European Commission now has to decide on its marketing authorisation across the EU.

Reactions to study suggesting Saturn's rings and tilt may be the product of a missing moon

Research published in Science proposes that an ancient moon of Saturn, which they have named Chrysalis (Chrysalis), may be responsible for Saturn's distinctive rings. According to the authors, the moon orbited around the gas giant for billions of years, but about 160 million years ago, it became unstable and moved too close to the planet, breaking apart under Saturn's tidal forces and forming the planet's rings. According to the research, Saturn's current tilt may also be related to the destruction of this moon.
