The research group from the University of Valencia (UV) that carried out the bibliometric research sought to identify the most productive authors and institutions between 2003 and 2005, as well as the composition of scientists in collaborative projects between authors and centres publishing their work in the leading reproductive biology journals.
The study has been recently published in Fertility and Sterility. The scientists appearing on the league table “can be considered as the elite in terms of research in the area; in other words they are at the cutting edge of scientific developments in this discipline”, Gregorio González-Alcaide, lead author of the study and a researcher at the López Piñero Institute of the History of Medicine and Science, a joint UV and CSIC centre, told SINC.
In total, the researchers studied 4,702 papers, of which 96.75% were the written in collaboration between two or more authors, while 73.73% of the research stemmed from collaboration between institutions. The authors identified 106 authors who had published more than nine studies, and calculated an average number of 5.24 researchers per study.
On this basis, Antonio Pellicer Martínez, Dean of the Faculty of Medicine and Odontology, and chair in Obstetrics and Gynaecology at the University of Valencia (UV) took fourth position, with 30 pieces of research published and 72 collaborations. The other Spaniard, in the number nine slot, is Carlos Simón, chair in Obstetrics and Gynaecology at the UV and the first researcher in Spain to have obtained cell lines from human embryo stem cells, with 24 papers. He is a researcher at the Valencian Stem Cell Centre and a member of the Valencian Infertility Institute (IVI).
Spain, among the top 20Spain takes the number 11 spot in terms of production of scientific research in the field of reproductive biology, with 159 studies published between 2003 and 2005, or 2.82% of total world production. In terms of work carried out, Spain undertook 100 collaborative projects, with the United States being the most frequent partner, in 19 projects. The United States and the United Kingdom are world leaders in terms of scientific production, with the US producing 1,541 papers (27.32% of total world production). These two countries “have led the league tables of absolute productivity (number of studies) in the area since the 1990s, although research is now emerging strongly in countries such as Canada and the People’s Republic of China”, points out
In terms of Spanish scientific centres, the Valencian Infertility Institute (IVI) is the most productive Spanish institution in the field of reproductive biology, occupying the number 33 spot at international level. France’s National Institute for Health and Medical Research and the University of Texas, USA, lead the productivity ranking, with 94 and 65 studies, respectively.
The bibliometric leader
At 1,491 pieces of research, the American journal Fertility and Sterility has published more studies within this discipline than any other scientific magazine. It is followed by the British journal Human Reproduction, with 1,400 and the highest average rate of papers per issue, and Biology of Reproduction, with 1,322.
The researchers chose reproductive biology as a subject to look in more depth at ‘scienciometric’ studies related to scientific sociology, because it is “an area of knowledge with great social relevance, and which has undergone significant growth over recent decades”, explained González.
During the bibliometric analysis, however, the researchers found some limitations in the quality of data sources (authors who do not always sign their studies in the same way), the coverage of the study, (which does not include all research within this field), and the way in which the study included analysis of co-authorship (with no uniform criterion for identifying networks of authors).

Plants and algae use the enzyme Rubisco to fix carbon dioxide, removing it from the atmosphere and converting it into biomass. Algae have figured out a way to increase the efficiency of carbon fixation. They gather most of their Rubisco into a ball-shaped microcompartment called the pyrenoid, which they flood with a high local concentration of carbon dioxide. A team of scientists at Princeton University, the Carnegie Institution for Science, Stanford University and the Max Plank Institute of Biochemistry have unravelled the mysteries of how the pyrenoid is assembled. These insights can help to engineer crops that remove more carbon dioxide from the atmosphere while producing more food.

Our brains house extremely complex neuronal circuits, whose detailed structures are still largely unknown. This is especially true for the so-called cerebral cortex of mammals, where among other things vision, thoughts or spatial orientation are being computed. Here the rules by which nerve cells are connected to each other are only partly understood. A team of scientists around Moritz Helmstaedter at the Frankfiurt Max Planck Institute for Brain Research and Helene Schmidt (Humboldt University in Berlin) have now discovered a surprisingly precise nerve cell connectivity pattern in the part of the cerebral cortex that is responsible for orienting the individual animal or human in space.
The researchers report online in Nature (Schmidt et al., 2017. Axonal synapse sorting in medial entorhinal cortex, DOI: 10.1038/nature24005) that synapses in...

Using ultrafast flashes of laser and x-ray radiation, scientists at the Max Planck Institute of Quantum Optics (Garching, Germany) took snapshots of the briefest electron motion inside a solid material to date. The electron motion lasted only 750 billionths of the billionth of a second before it fainted, setting a new record of human capability to capture ultrafast processes inside solids!
When x-rays shine onto solid materials or large molecules, an electron is pushed away from its original place near the nucleus of the atom, leaving a hole...
For the first time, physicists have successfully imaged spiral magnetic ordering in a multiferroic material. These materials are considered highly promising candidates for future data storage media. The researchers were able to prove their findings using unique quantum sensors that were developed at Basel University and that can analyze electromagnetic fields on the nanometer scale. The results – obtained by scientists from the University of Basel’s Department of Physics, the Swiss Nanoscience Institute, the University of Montpellier and several laboratories from University Paris-Saclay – were recently published in the journal Nature.
Multiferroics are materials that simultaneously react to electric and magnetic fields. These two properties are rarely found together, and their combined...
