The vast majority of mammals remain fertile until the end of their lives. Humans and some species of whales deviate from that norm and do go through menopause. Now, research published in Science reveals that menopause exists in female chimpanzees, too, and that it lasts for a fifth of their adult lifespan. To reach these conclusions, the research team observed 185 female chimpanzees between 1995 and 2016 in Uganda's Kibale National Park and measured hormone levels in urine samples from specimens of various ages.
A meta-analysis, pooling the results of 40 previous studies - involving more than 310,000 children and adolescents in total - concludes that treatment rates for mental disorders in these age groups are "generally low, especially for depression and anxiety". The research, published in JAMA Network Open, shows that the treatment rate for any mental disorder is 38%, ranging from 31% for anxiety, 36% for depression, 49% for conduct disorders and 58% for attention deficit hyperactivity disorder (ADHD).
Spermidine is a naturally occurring compound that has been linked to increased longevity in some organisms. New research shows that supplementation with this compound improves oocyte quality and fertility in older female mice. If its action and safety in humans is confirmed, the authors argue that it could serve as a therapeutic strategy to "improve the reproductive outcome of older women, either through natural pregnancy or assisted reproductive technologies". The results are published in the journal Nature Aging.
A study published in Nature has analyzed the presence of human settlements in flood-prone areas and their evolution worldwide since 1985. Until 2015, there was an increase of up to 122% in these settlements in flood-prone areas. According to their data, in many regions, the growth in the most hazardous areas is far outpacing development in non-exposed areas, especially in East Asia.
The Royal Swedish Academy of Sciences has awarded the 2023 Nobel Prize in Physics to Pierre Agostini, Ferenc Krausz and Anne L'Huillier for developing "experimental methods generating attosecond light pulses". These advances made it possible to observe the motion of particles in atoms on the shortest time scale captured by humans. An attosecond is a unit of time equivalent to one trillionth of a second, roughly the time it takes light to travel the diameter of an atom.
Las lluvias torrenciales caídas en Libia hace dos semanas fueron 50 veces más probables por el calentamiento global provocado por la acción humana. Algo similar ocurría con las lluvias caídas en Grecia, Bulgaria y Turquía, que fueron 10 veces más probables por el cambio climático, según concluye un estudio de atribución rápido de la Word Weather Attribution (WWA). La investigación apunta a que la tragedia en Libia se agravó por otros factores humanos, como construcciones en llanuras inundables y presas en mal estado. Los autores también analizaron las inundaciones registradas en España a principios de septiembre y concluyeron que precipitaciones tan intensas se esperan una vez cada 40 años.
According to a new report from the Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services (IPBES), human activities have introduced over 37,000 exotic species to regions around the world. The document highlights that more than 3,500 of these are harmful invasive exotic species that are often overlooked until it's too late.
The International Agency for Research on Cancer (IARC) and the Joint FAO/WHO Expert Committee on Food Additives (JECFA) have published a health impact assessment of the sweetener aspartame. Citing "limited evidence" of carcinogenicity in humans, IARC has classified aspartame as possibly carcinogenic to humans (Group 2B). For its part, JECFA has not changed the acceptable daily intake of this sweetener, which is set at 40 mg/kg body weight. According to these bodies, with one can of diet soft drink containing 200-300 mg aspartame, a 70 kg adult would need to consume more than 9-14 cans per day to exceed the acceptable daily intake - assuming no other intake from other dietary sources.
The Anthropocene Working Group of the International Commission on Stratigraphy has proposed Crawford Lake in Canada as a reference site for studying the Anthropocene as a possible geological epoch. This proposal for a Global boundary and Stratotype Section and Point (GSSP) was presented today at the International Congress of Stratigraphy in Lille, France. It is a necessary, but not sufficient step for the Anthropocene to enter the International Chronostratigraphic Table, the worldwide reference for geological units. Once approved by the AWG, this proposal has to go through three more votes in international geological bodies.
The term Anthropocene describes the profound changes on Earth due to human activities in the past decades. The concept comes from geology but has spread to other areas and has sparked controversy within science. In this article, we provide some keys to understand what the Anthropocene is, and why there has been debate in recent days surrounding its possible declaration.
