The study of protein material of a homo tooth antecessor of Atapuerca becomes the oldest human genetic evidence and clarifies the debate about our antecessors

The study, carried out by the University of Copenhagen and in which the scientific director of the Museum of Human Evaolution of Burgos: Juan Luis Arsuaga participated, determines very precisely the position of Homo antecessor in the human genealogical tree and shows that it had a close relationship with the Neanderthals, the Denisovans and modern human. The Museum of Human Evolution is the only museum in the world that exhibits original fossils of this species.

Recent study describes a new species of mustelidae that lived in the Miocene, 9 million years ago

Circamustela peignei is the name given to the new species described by a team of researchers from the National Museum of Natural Sciences (MNCN-CSIC), the Institut Català de Paleontologia Miquel Crusafont and the Iziko Museum in South Africa, among other institutions. It is a small carnivore that lived in the centre of the Iberian peninsula 9 million years ago. The studied remains were discovered at the Batallones-3 and 5 deposit at Cerro de los Batallones in Torrejón de Velasco (Madrid).

Electric cars better for climate in 95% of the world

The latest research by University of Cambridge, Exeter and Nijmegen shows that reports have questioned whether electric cars really are ‘greener’ once emissions from production and generating their electricity are taken into account. However, this study has concluded that electric cars lead to lower carbon emissions overall, even if electricity generation still relies on fossil fuels. They assured that under current conditions, driving an electric car is better for the climate than conventional petrol cars in 95% of the world. The results are reported in the journal Nature Sustainability.

Imaging and treating cancer with an iridum-based prodrug

The Royal Society of Chemistry shows that a novel cancer-targeting iridium complex is demonstrated to act as an effective radiosensitiser for image-guided cancer radiochemotherapy. This allows visualisation of tumor sites in mice for precise irradiation with X-rays. Alongside imaging, the complex displays chemotherapeutic and radiosensitisation potency by inducing mitochondrial dysfunction.  Combined, the DNA damage caused by x-rays and iridium complex-induced mitochondrial dysfunction have been found to promote cancer cell death. According to the author, the sensitivity enhancement ratio of the prodrug is the highest among those reported for radiotherapy metal complex drugs.
