Scientists demonstrated that, contrary to what had been assumed for several years, colour variations among female macaques do not precisely indicate the time of ovulation. On the other hand, dominant female macaques, who usually have greater reproductive success, have darker hindquarters.
The unrelenting deforestation of the Amazon region could lead to a dramatic increase to the risk of destructive wildfire outbreaks, research has shown.
A research team led by Leonor Saúde, Principal Investigator at Instituto de Medicina Molecular, in partnership with the company Technophage, SA, has designed a simple and efficient platform that uses zebrafish to discover and identify new drugs to treat spinal cord lesions. This study, published today in Scientific Reports, is the proof-of-concept for the use of this zebrafish platform that, combined with drug repurposing, has the potential to accelerate the translation period from the discovery to the clinics.
Researchers have shown for the first time that cigarette butts reduce plant growth. Cigarette butts are the most common form of litter worldwide, with an estimated 4.5 trillion discarded annually.
The Turkestan cockroach (commonly known as the red runner roach or rusty red roach), which is popular as food for pet reptiles, has an interneuron extremely sensitive to sex pheromones emitted by American cockroaches, providing evidence that the Turkestan cockroach is phylogenetically close to the American cockroach and the smoky brown cockroach belonging to the genus Periplaneta.
Researchers at the University of Illinois and University of California, Los Angeles described a novel biochemical strategy used by bacteria to synthesize natural products.
Researchers at NHGRI have performed the largest GWAS study on type 2 diabetes in the sub-Saharan African populations, revealing an association between the disease and previously unlinked ZRANB3 gene. By using animal models, their results show that dysfunction of the ZRANB3 gene has major repercussions on insulin production. This link may hold key answers to the treatment of type 2 diabetes in all populations.
A national population-based study suggests the 2016 US presidential election may have been associated with an increase in preterm births among Latina women in the United States. The design of the study is used to evaluate whether policies or other population-level changes interrupt a trend in an outcome.
The number of women using cannabis in the year before they get pregnant and early in their pregnancies is increasing, and their frequency of use is also rising, according to new data from Kaiser Permanente.
Through a participatory forest-carbon monitoring project in the Darien forest of Panama, scientists and a team of trained indigenous technicians found that, even in disturbed areas, it maintained the same tree species richness and a disproportionately high capacity to sequester carbon.
