The Ciampate del Diavolo (Neapolitan: "Devil's Footprints" or "Devil's Trails") is a locality near the extinct Roccamonfina volcano in northern Campania, Italy. It is named after fossilised footprints preserved in pyroclastic flow deposits that have been dated to around 350,000 years ago. They have been attributed to bipedal hominids, possibly Homo heidelbergensis, which is known to have inhabited the region at the time.

The footprints comprise three sets of tracks indicating that three hominids made their way down a steep slope on the flank of the volcano, away from the crater. The tracks were preserved under a layer of volcanic ash and were revealed by erosion, probably in the late 18th to early 19th century. Local people attributed the prints to the Devil as they regarded him as the only being capable of walking on lava without harm. They were identified as hominid footprints after archaeologists examined them in 2002 and are the second oldest set of hominid footprints known outside Africa, after the Happisburgh footprints.

Nature is a British weekly scientific journal founded and based in London, England. As a multidisciplinary publication, Nature features peer-reviewed research from a variety of academic disciplines, mainly in science and technology. It has core editorial offices across the United States, continental Europe, and Asia under the international scientific publishing company Springer Nature. Nature was one of the world's most cited scientific journals by the Science Edition of the 2019 Journal Citation Reports (with an ascribed impact factor of 42.778), making it one of the world's most-read and most prestigious academic journals. As of 2012, it claimed an online readership of about three million unique readers per month.Founded in autumn 1869, Nature was first circulated by Norman Lockyer and Alexander Macmillan as a public forum for scientific innovations. The mid-20th century facilitated an editorial expansion for the journal; Nature redoubled its efforts in explanatory and scientific journalism. The late 1980s and early 1990s created a network of editorial offices outside of Britain and established ten new supplementary, speciality publications (e.g. Nature Materials). Since the late 2000s, dedicated editorial and current affairs columns are created weekly, and electoral endorsements are featured. The primary source of the journal remains, as established at its founding, research scientists; editing standards are primarily concerned with technical readability. Each issue also features articles that are of general interest to the scientific community, namely business, funding, scientific ethics, and research breakthroughs. There are also sections on books, arts, and short science fiction stories.

The main research published in Nature consists mostly of papers (articles or letters) in lightly edited form. They are highly technical and dense, but, due to imposed text limits, they are typically summaries of larger work. Innovations or breakthroughs in any scientific or technological field are featured in the journal as either letters or news articles. The papers that have been published in this journal are internationally acclaimed for maintaining high research standards. Conversely, due to the journal's exposure, it has at various times been a subject of controversy for its handling of academic dishonesty, the scientific method, and news coverage. Fewer than 8% of submitted papers are accepted for publication. In 2007, Nature (together with Science) received the Prince of Asturias Award for Communications and Humanity.
