Snakes and spiders evoke fear and disgust in many people, even in developed countries where hardly anybody comes into contact with them. Until now, there has been debate about whether this aversion is innate or learnt. Scientists have recently discovered that it is hereditary: Even babies feel stressed when seeing these creatures - long before they could have learnt this reaction.
'Kronos' is enhanced in metals and other rock-forming elements but not in volatiles, prompting a team of researchers to conclude that it absorbed as much as 15 Earth masses worth of rocky planets. Its twin, 'Krios,' does not show this unusual pattern of enhancement.
Scientists have completed new simulations that could provide insight into how blobs at the plasma edge behave. The simulations performed kinetic simulations of two different regions of the plasma edge simultaneously.
Controlling and moving light poses serious challenges. One major hurdle is that light travels at different speeds and in different phases in different components of an integrated circuit. For light to couple between optical components, it needs to be moving at the same momentum. Now, a team of researchers has demonstrated a new way to control the momentum of broadband light in a widely-used optical component known as a whispering gallery microcavity (WGM).
Fruit flies have surprising similarities to humans. The mysteries of a broad range of human conditions can be studied in detail in these organisms, however this often requires the use of expensive custom equipment. team of scientists now present the ethoscope -- a cheap, easy-to-use and self-made customizable piece of equipment of their invention that can be used to study flies' behavior.
Through the combined effect of flexoelectricity and piezoelectricity, researchers have found that polar materials can be made more or less resistant to dents when they are turned upside down... or when a voltage is applied to switch their polarization. This research points to the future development of 'smart mechanical materials' for use in smart coatings and ferroelectric memories.
A British enthusiasm for feeding birds may have caused UK great tits to have evolved longer beaks than their European counterparts, according to new research. The findings identify for the first time the genetic differences between UK and Dutch great tits which researchers were then able to link to longer beaks in UK birds.
Researchers use liquid metal to create atom-thick 2-D never before seen in nature. The research could transform how we do chemistry and could also be applied to enhance data storage and make faster electronics.
New research suggests that the last common ancestor of apes -- including great apes and humans -- was much smaller than previously thought, about the size of a gibbon. The findings, published today in the journal Nature Communications, are fundamental to understanding the evolution of the human family tree.
Some plants behave like the mythical monster Hydra: Cut off their heads and they grow back, bigger and better than before. A new study finds that these 'overcompensators,' as they are called, also augment their defensive chemistry -- think plant venom -- when they are clipped. The discovery could lead to the development of new methods for boosting plant growth while reducing the need for insecticides, the researchers said.
