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 Nature identifies a metabolite produced during exercise that can effectively reduce food intake and obesity in mice. It has also been found in humans.
Brain lesions that cause spontaneous remission of tobacco addiction in humans affect a brain circuit common to different addictive behaviours, concludes a study published in Nature Medicine. Understanding this brain network opens the way to new therapies against addiction.
A metagenomic comparison of the infant gut microbiome of industrialised and non-industrialised populations reveals robust differences that researchers say are lifestyle-dependent. The research involved samples from infants of Hadza, a group of modern hunter-gatherers living in Tanzania, and is published in the journal Science.
In a press release published this week, Moderna has shared the first data on its new bivalent adapted vaccine against Omicron.
A study of nearly half a million adults examines the association between total and specific fish intake and melanoma risk.
A study published in PLoS Medicine examines the effect of traffic noise near schools on children's attention and memory development, compared to those who study in quieter environments.
Glyphosate is one of the most widely used herbicides in the world. New work published in Science reveals that it significantly impairs the ability of bumblebees to maintain the temperature of their hive, a hitherto unsuspected effect that may lead to the decline of this already endangered species, which is essential for pollination.
A review with meta-analysis published in the journal PLoS Medicine concludes that the percentage of asymptomatic people with covid-19 is lower, and that they are less contagious than those who are pre-symptomatic or symptomatic.
An international team led by researchers at the University of Copenhagen has detected a new class of extremely reactive chemical compounds in tha atmpsphere, the 'trioxides'. The challenge now is to understand the role of trioxides in climate and air quality. The result is presented in Science.
A 'quantum internet' would allow, among other things, the flow of inviolable secret messages. Building such a network involves teleporting information between non-interacting elements of the system, something researchers in the Netherlands claim to have achieved. They publish it in Nature.
