What is a chorus, what is an insect chorus, and why might we be interested in how and why singing insects create orchestral productions? To begin, chorusing is about timing. In a chorus, singers align their verses with one another in some non-random way. When singing insects form a chorus, the alignment may only be […]
The authors of a recent study published in Genome Biology and Evolution set out to uncover early genetic changes in bees and wasps on the path to sociality.
In the first half of the century, the three great killers among endemic diseases—smallpox, malaria, and tuberculosis—raging around the world (we think today of malaria as a tropical malady but in the 1920s there were outbreaks as far north as Siberia) were each responsible for more deaths than the 80 million who died in both world wars. Innovations stemming from the Second World War, an immense hothouse of technological progress, made it possible to contemplate combatting infectious disease on a global scale.
There are a lot of peculiar phrases in Moby-Dick. My new introduction to the second Oxford World’s Classics edition of Herman Melville’s novel highlights the startling weirdness of the book, both in its literary form and its language.
The origin of the word blatherskite ~ bletherskate “foolish talk; foolish talker” is supposedly secure. The Oxford Etymologist investigates…
Food plays an important role in brain performance and health. In our review, we outline the role of diet in five key areas: brain development, signalling networks and neurotransmitters in the brain, cognition and memory, the balance between protein formation and degradation, and deteriorative effects due to chronic inflammatory processes.
The posts for the last two weeks dealt with the various attempts to trace (or rather guess) the origin of the word bizarre, and I finished by saying that the word is, in my opinion, sound-imitative. In connection with this statement a caveat is in order…
This story continues the attempts of the previous week to catch a flea. Anyone who will take the trouble to look at the etymology of the names of the flea, louse, bedbug, and their blood-sucking allies in a dozen languages will discover that almost nothing is known for certain about it. . This fact either means that we are dealing with very old words whose beginnings can no longer be discovered or that the names have been subject to taboo (consequently, the initial form is beyond recognition), or, quite likely, both factors were in play.
Stinging and gnawing insects are not only a nuisance in everyday life; they also harass etymologists. Those curious about such things may look at my post on bug for June 3, 2015. After hovering in the higher spheres of being (eat, drink, breathe: those were the subjects of my most recent posts), I propose to return to earth and deal with low, less dignified subjects.
Many people view evolution as an extremely slow, long-term process by which organisms gradually adapt and diversify over millennia. But researchers also have found that rapid evolutionary change can occur over mere centuries, or even decades. Such ongoing rapid evolution is the focus of a fast-moving field of empirical work, made easier by new techniques […]
I have spent the last fifty years studying the eyes and vision of animals, including man. During that time there have been many discoveries and ideas from vision research that have intrigued me, most of these are known to other scientists, but not more widely.
Great truths are often so pervasive or in such plain view as to be invisible. This is the case with bees and their food plants, the world’s quarter million flowering plant species, especially because it’s easy to overlook small things in a world in which whales and elephants hold the imagination of the public. Little […]
Tool use, once considered unique to our species, is now known to be widespread in the animal kingdom. It has been reported in most of the major taxonomic groups, with notable exceptions being myriapods, amphibians and reptiles. In insects, one of the best documented examples of tool use is seen in members of the ant […]
Honey bee colonies have historically been considered as marvels of evolution resulting in perfectly cooperative and harmonious societies, and exemplars of what we humans might achieve. This is an appealing image to many, but it is of course a caricature. Nobody is perfect, not even honey bees.
In the agricultural industry, recombinant DNA technology allows for DNA to be transferred from one organism to another, creating Genetically Modified Organisms (GMOs). Four crops constitute the vast majority of the GM crop production: maize, canola, soybean, and cotton. Since 1995, GM crops have been grown commercially and the global area sown to these crops has expanded over 100-fold over the past two decades.
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.
