Rarely do esoteric academic debates, especially those concerning methodology, make their way into the popular press. But, for the past two years, a major controversy on the replication of psychological research has spilled into public view and shows few signs of abating. However, the debate is silent about the far more problematic conceptual crisis that challenges the core principles of scientific psychology.
Contrary to common belief, black holes don’t swallow everything that comes nearby. In fact, they expel a good part of the gas of the centre of galaxies. This happens when a wind of ionized gas is formed in the vicinity of the black hole. In the case of supermassive black holes that occur at the centre of many galaxies, they produce a wind that can interact with the galaxy itself shaping its evolution through time.
One of the goals of our trip was to search for a butterfly called Heliconius tristero (or Heliconius timareta tristero as it is now more correctly known), which had been described in 1996 from just two specimens collected in this area. Almost anyone who has visited the jungles of tropical America is likely to be familiar with the ‘postman’ or Heliconius butterflies.
Recent research reflects some of this range of aetiological factors that influence childhood obesity. Global perspectives from countries of study including Brazil, Australia, England, South Africa, China, and a review of the international literature cover topics frequently reported by the media, like the food environment, unhealthy food advertising policy, weight management interventions, and associations with gender and sleep.
One advantage to the clinician of the technological revolution is the rapid access to medical information. Every morning I spend ten minutes over coffee looking through the latest Twitter feeds from the major medical journals, to skim through what research might be emerging in fields other than my own niche (I still enjoy reading the paper editions of journals to cover my specialist area).
As I set out to unpack the challenges of happy travel, I first had to confront my assumption that travel truly is a worthwhile investment of time and money. We certainly seem to think it is. When people sit down to construct a bucket list, travel goals shoot right to the top. A quick browse through the website bucketlist.org reveals a deep longing for far-flung adventures
That we remember the past is obvious. But as well as the ability to recall what has already happened to us, we are also able to imagine what might happen to us in the future. Is this capacity for prospection important? Absolutely. Being able to anticipate what might happen and take relevant steps, prioritise goals, and form plans of action for what we are going to do have been fundamental to our evolutionary success.
The world is becoming more globalised, with the number of people traveling each year on the rise. US residents are taking nearly two billion leisure trips and almost 500 million business trips (2016), with UK residents making 70.8 million visits overseas last year (2016), an 8% increase to the previous year (2015). With travel visits increasing year on year on a worldwide scale, it is no wonder travel medicine is an area also growing quickly to match activity and demand.
The history of aviation spans over two thousand years – from the earliest kites in Ancient China to balloons in eighteenth century France, to military drones and reconnaissance. Early aviation was a dangerous past-time, with many pilots meeting untimely ends as a result of their desire to reach further and higher than ever before. We’ve taken a look at some of these early aviators and their attainments
The discovery in Jebel Irhoud, Morocco of human fossils with modern facial features, similar to ours, has been a wonderful surprise, even outside the world of anthropology. The discoveries have been published in the journal Nature by Jean-Jacques Hublin and collaborators. The fossils are associated with tools from the Middle Stone Age, the technique immediately preceding the Upper Pleistocene.
After months of working 40+ hour weeks, running the kids from one activity to the next, and managing a household, the time has arrived: vacation. You’ve carefully planned a week-long getaway at a seaside resort, and can think of nothing better than basking in the sun, reading a novel, and sipping a cocktail. You arrive with eager anticipation. The beach is perfect, the resort restful and luxurious.
These are divided times. In Washington, a new administration has deepened the polarization of an already gridlocked political process. In the media, our disagreements are expressed, and often amplified, by a host of competing voices. The questions they address include: how should the Constitution be interpreted? Should we embrace free trade or focus on rebuilding our industrial base?
The singer Madonna had a worldwide hit record in the 1980s (‘Material Girl’) in which she described herself as ‘the material girl living in a material world’. This is a prescient phrase for the world of today some 30 years after the release of this record. Although Madonna may have been referring to wealth and ‘cold hard cash’ in her song, the rapid development of goods for professional and consumer use really do put us at the mercy of all things material.
With the rise of the internet and electronic research resources, it is not uncommon for a librarian to hear that libraries are no longer necessary. “You can find anything on the internet” is an often heard phrase. What most of those people do not realize is how integrated librarians (and information scientists) are in organizing and providing information to the public.
In her 1998 essay in Science, Jane Lubchenco called for a “Social Contract for Science,” one that would acknowledge the scale of environmental problems and have “scientists devote their energies and talents to the most pressing problems of the day.” We were entering a new millennium, and Lubchenco was worried that the scientific enterprise was unprepared to address challenges related to climate change, pollution, health, and technology.
As eclipse 2017 quickly approaches, Americans—from astronomers to photographers to space enthusiasts—are preparing to witness the celestial wonder that is totality. Phenomenon found within planetary science has long driven us to observe and study space. Through a shared desire to dismantle and reconstruct the theories behind our solar system, ancient Greek philosophers and scientists built the foundation of planetary astronomy.
