This article looks briefly at how our current supremely woolly concept of the genus Homo has come about, as background for urging a more rational approach to defining it.

The palaeogenomics (ancient DNA) field can be defined as the recovery and analysis of genetic material from the biological remains of the past and has become a powerful scientific field that provides direct information about the evolutionary process through space and time.

Recent paleoanthropological evidence from the early Pleistocene site of Dmanisi in Georgia has revealed that the first hominins out of Africa were more archaic than the coeval African and Asian Homo erectus.

Despite the bewilderment caused the almost continuous bombardment of news about the discovery of a new fossil that revolutionizes everything we knew until now about human evolution, at the beginning of the twenty-first century, there is a broad consensus regarding certain key moments in our evolution.

The Riemann hypothesis is an unproven statement referring to the zeros of the Riemann zeta function.

Mathematically, the motion of a fluid is described by the so-called Navier-Stokes equations. In the spirit of Newtonian mechanics, these equations should determine the future motion of the fluid out of its initial state.

The aim of this article is to highlight some previous challenges that were also a stimulus to finding proof for some interesting results. With this pretext, we present three moments in the history of mathematics that were important for the development of new lines of research.

The Hodge conjecture, proposed in 1950, is one of the seven millennium problems, and is framed within differential geometry and algebraic geometry.

The Poincaré conjecture is a topological problem established in 1904 by the French mathematician Henri Poincaré. It characterises three-dimensional spheres in a very simple way. This problem was directly solved between 2002 and 2003 by Grigori Perelman, and as a consequence of his demonstration of the Thurston geometrisation conjecture.

The Clay Mathematics Institute made a list of seven problems in May 2000; they were called the «millennium problems». Finding their solution has an added incentive: each solver will receive a million dollars as a prize.

Scientific philosophy is that which is informed by science. It uses exact tools such as logic and mathematics and provides a framework for scientific activity to solve more general questions

The universe at large is dominated on the one hand side by gravity and on the other by weakly interacting particles. The identity of dark matter remains an unresolved mystery of the universe. Meanwhile neutrinos have matured from their status as ghost particles to distinctly visible messengers for some of the most intriguing astrophysical phenomena.

The gamma-ray radiation represents the most energetic «light» of the electromagnetic spectrum.

X-ray emission from cosmic sources indicates that these sources are heated to temperatures exceeding a million degrees. These observations greatly impacted our understanding of the physics governing the evolution of structures across the universe.

We see the sky and admire its regularity and stability, its apparent immutability. We have always done so; it does not come as a surprise, since humans have always been startled by any change in the sky, associating it with omens or the mood swings of gods. At that time, they might call these changes «new stars», even if they were, for example, a supernova explosion, as in the case of Tycho’s supernova in the sixteenth century.

Els neutrins són partícules neutres que tan sols interactuen dèbilment, la qual cosa les converteix en poderoses fonts d’informació sobre els processos més energètics de l’univers, però es necessiten detectors de dimensions gegantines ubicats al fons del mar o davall el gel antàrtic per a poder detectar-los.

In this article, we summarise several of the most well-known astrophysical scenarios, and offer a brief description of what we currently know about them.

Understanding the nature of the main constituents of the universe is crucial to obtain a precise description of the way in which it reached its present state.

Genre Egalité et Mixité is a interdisciplinary research group on gender in education, created at the University of Lyon, that explores this issue along three axes: teacher training, scientific research, and the creation of a specialised library. Coming from several disciplines, its researchers have different profiles and consequently, different conceptions of feminism, making the team unique.

Recent gender analyses have been opening new paths for innovation and excellence. They are the basis for the Gendered Innovations project. However, this work did not come out of nowhere; it is supported by decades of gender and science studies.

The institutionalisation of equality policy in science should facilitate progress towards equality in a space that wants to consider itself merit (and ability) driven.
