À propos de l’article Dans le cadre de la théorie de la niche écologique, l'environnement agit comme un filtre et sélectionne les espèces d'une communauté locale. Le concept de filtrage environnemental explique que tous les organismes ne peuvent pas s'établir et persister dans tous les environnements. Les études qui examinent les relations entre les traits…
The following problem appeared in Volume 96, Issue 3 (2023) of Mathematics Magazine. Evaluate the following sums in closed form: $latex \displaystyle \sum_{n=0}^\infty \left( \cos x - 1 + \frac{x^2}{2!} - \frac{x^4}{4!} \dots + (-1)^{n-1} \frac{x^{2n}}{(2n)!} \right)$ and $latex \displaystyle \sum_{n=0}^\infty \left( \sin x - x + \frac{x^3}{3!} - \frac{x^5}{5!} \dots + (-1)^{n-1} \frac{x^{2n+1}}{(2n+1)!} \right)$.…
Black Bone Chickens (BBCs) are famous for their striking black skin, bones, and tissues, caused by a unique genetic trait. Our study focused on the Id locus, which inhibits pigmentation. Using public datasets, we discovered a rearrangement that explains BBCs unique features and their evolution.
High-resolution observations and multi-waveband optical constraints from ground-based and satellite data in Xuzhou, China, and Dhaka, Bangladesh, reveal that urban riverbanks and small industrial sites are often overlooked sources of black carbon emissions in Asian cities.
Over half of our genomes consist of thousands of remnants of ancient viral DNA, known as transposable elements, which are widespread across the tree of life. Once dismissed as the "dark side" of the genome, researchers at Helmholtz Munich and Ludwig-Maximilians-Universität (LMU) have now revealed their crucial role in early embryo development. The study is published in the journal Cell.
