From Darwin to Desmond Tutu, and numerous Nobel Prize winners in between, discover which well-known academics have published in our journals over the course of 140 years through our interactive timeline.
Sometimes spouses will look back on the time of their getting to know one another and say, half-jokingly, that on a given occasion one was putting the other to the test.
For too long, presentations of science for the general public, and education in schools, has suggested that science wields a sort of hegemonic power, as if its terms and methods gradually replace and make redundant all other discourse; the only reason it has not yet completed its conquest is that the world is complicated—but it is only a matter of time…
In 1969, half a century ago, astronauts first landed on Earth’s sole moon. The first successful robotic landers touched down on the much more distant Venus and Mars in 1970 and 1976, respectively, and in the same decade spacecraft flybys provided the first, fleeting close-ups of Jupiter and Saturn. It was not until two decades […]
With over 10 million active researchers, more than 2 million scientific articles published each year, and an uncontrolled spread of bibliometric indicators, contemporary science is undergoing a profound change that is modifying consolidated procedures, ethical principles that were deemed inalienable and traditional mechanisms for the validation of scientific outputs that have worked successfully for the last century.
The central regions of galaxies are extremely crowded places, containing up to a few hundreds of millions of stars. They are generally extremely dense environments, where a variety of phenomena occur frequently.
Human communication takes many forms, but picturing humans using chemical mechanisms to send messages leaves us skeptical. However, this concept becomes more plausible when we think of communication mediated via pheromones in animals.
The title of a research article has an almost impossible remit. As the freely available representative of the work, it needs to accurately capture what was achieved, differentiate it from other works, and, of course, attract the attention of the reader, who might be searching a journal’s contents list or the return from a database query.
Galileo was proud of his parabolic trajectory. In his first years after arriving at the university in Padua, he had worked with marked intensity to understand the mathematical structure of the trajectory, arriving at a definitive understanding of it by 1610—just as he was distracted by his friend Paolo Sarpi who suggested he improve on the crude Dutch telescopes starting to circulate around Venice.
Most practicing scientists scarcely harbor any doubts that science makes progress. For, what they see is that despite the many false alleys into which science has strayed across the centuries, despite the waxing and waning of theories and beliefs, the history of science, at least since the ‘early modern period’ (the 16th and 17th centuries) is one of steady accumulation of scientific knowledge. For most scientists this growth of knowledge is progress. Indeed, to deny either the possibility or actuality of progress in science is to deny its raison d’être.
A span of nearly 300 years separates Galileo Galilei from Lord Rayleigh—Galileo groping in the dark to perform the earliest quantitative explorations of motion, Lord Rayleigh identifying the key gaps of knowledge at the turn into the 20th century and using his home laboratory to fill them in. But the two scientists are connected by a continuous thread.
In 2014, PLOS Biology published an article about a cousin of ours, a member of the Sono Community of wild chimpanzees in the Budongo Forest in northwestern Uganda. In a video shared in relation to the study, an alpha male, NK, gathers moss from a tree trunk just within his reach, a prize he will use to lap up water in a nearby pool.
Newton’s famous remark, “If I have seen further it is by standing on the shoulders of Giants,” is not in his published work, but comes from a letter to a colleague and competitor. In context, it reads simply as an elaborately polite acknowledgment of previous work on optics, especially the work of the recipient of the letter, Robert Hooke.
What do we mean by “the Universe”? In the physics community, we would define “the Universe” as all “observable things”, ranging from the entire cosmos to stars and planets, and to small elementary particles that are invisible to the naked eye. Observable things would also include recently made discoveries that we are slowly coming to understand more, such as the Higgs boson, gravitational waves, and black holes.
Spiral galaxies like the Milky Way and its neighbour, the Andromeda Galaxy, contain about 100 billion stars each, the light of which can be seen by eye. Also visible are small amounts of dust, typically enshrouding the sites of young star formations.
The current era in the Western hemisphere is marked by growing public distrust of “intellectual elites.” The present U.S. administration openly disregards, or even suppresses, relevant scientific input to policy formulation.
