To date, more than 6,000 exoplanets — planets orbiting a star other than the Sun — have been discovered, but no moon outside the Solar System — known as an exomoon — has ever been definitively identified. Now, a study published in Nature presents evidence of what could be an exomoon orbiting a brown dwarf — an object halfway between a star and a planet. By analysing radial velocity data from observations made by the European Southern Observatory’s (ESO) Very Large Telescope, a team has identified a signal indicating the presence of a satellite with a minimum mass of 0.9 times that of Jupiter and an orbital period of around 170 days. “Although it is unclear whether this exosatellite will meet the criteria—yet to be defined—for being considered an exomoon, it represents an important step towards that first indisputable detection,” the authors state.
Between 1990 and 2023 in Spain, cases of infertility among women aged between 35 and 49 rose from around 975 cases per 100,000 women in this age group to 2,226 cases per 100,000, figures that are below the European average. Overall, this age-adjusted prevalence rose in all regions of the world during the same period. The study has been published in The Lancet Obstetrics, Gynecology, & Women’s Health.
A review published in The Lancet Psychiatry has examined the prevalence of major depressive disorder during pregnancy, the peripartum period—immediately before and after childbirth—and the postpartum period—up to twelve months after childbirth. The study, which used data from more than two million women and girls aged 10 to 59 from all regions of the world, showed that approximately one in 15 (6.8%) is affected by major depression during the year following childbirth and that the prevalence was highest during the first two weeks after childbirth (8.3%). The authors call for greater integration of screening, prevention, and treatment of this disorder during the peripartum period into current care models.
Craig Venter, the American biologist and entrepreneur who founded Celera Genomics to launch his own Human Genome Project in 1999 outside the public consortium, died Wednesday in San Diego at the age of 79, according to a statement from the J. Craig Venter Institute, which he led. Among other achievements, Venter completed the first full sequencing of a living organism’s genetic material and announced that he had succeeded in creating synthetic life.
The German mathematician Gerd Faltings has won the Abel Prize, awarded by the Norwegian Academy of Science and Letters. Faltings, director emeritus of the Max Planck Institute for Mathematics, became a celebrity at the age of 29 for proving a conjecture that earned him the Fields Medal in 1986. His contributions have revolutionised arithmetic geometry, a branch of mathematics at the intersection of the two oldest: number theory and geometry.
Spina bifida is a congenital malformation in which the spinal column does not close completely. A team in California (USA) has completed a phase 1 clinical trial testing, for the first time, a stem cell treatment combined with standard foetal surgery. The trial was conducted on six pregnant women with foetuses diagnosed with myelomeningocele, the most severe form of spina bifida. The six babies, born between 2021 and 2022, maintained the repair intact and had no serious adverse effects. The team will follow up carefully to ensure that the treatment remains safe and improves the children's quality of life. The results are published in The Lancet.
A team from the United States has analyzed nearly twenty studies on melatonin use in children between the ages of 0 and 6 in different countries. Although it appears that melatonin can help improve sleep onset in children with neurological conditions such as autism spectrum disorders, the data indicate that in recent years there has been an increase in sales of these products without a clear understanding of their actual effectiveness and potential long-term consequences for typically developing young children. The results are published in JAMA Network Open.
A research team identified five major phases of brain topology throughout human life—changes in the structure of neural connections—as detailed in an article published in Nature Communications. Using brain images from 3,802 people between the ages of 0 and 90, it defines four turning points around the ages of 9, 32, 66, and 83.
The power of communication to represent violence against women has been on the table for scientific and social debate for more than two decades. However, after 25 years of manuals on how to address gender-based violence in journalism, inadequate coverage persists, still romanticising it or simplifying its approach as emotional violence.
An investigation published in JAMA Neurology concludes that obstructive sleep apnoea is associated with an increased risk of Parkinson's disease, according to the medical records of more than 11 million American war veterans, mainly men. The article also indicates that this risk can be reduced by early treatment with continuous positive airway pressure, suggesting intervention in sleep-disordered breathing as a strategy for preventing neurological diseases.
