The public is turning out to be, whether knowingly or not, animal ethnographers. The diversity of pets, farm animals, and wild animals they track with lens is exposing the rarest of behaviors. These behaviors not only make intriguing viewing but serve to widen our thinking about the animal world and perhaps diminish our iron-gripped hold on cleverness. Might we be less willing to destroy creatures whom we believe are ‘smart’?
The existence of gravitational waves, or ripples in the space-time, is no more just a speculation but a firm truth, after the recent direct detection of such waves from at least two pairs of merging black holes by the LIGO gravitational-wave detector. In such a binary system, two black holes orbit each other at a close separation, nearly at the speed of light, whirling the spacetime in their neighbourhood.
Many factors influence the outcome of war. But what has soil got to do with war? I suspect few have given much thought to the influence of soil on war, or, conversely, how war influences the soil. But the role of soil in warfare can be considerable, as can the impact of war on soil, which can often leave it unusable. The most dramatic and emotive examples of the role of soil in war comes from the First World War.
From tornadoes and typhoons to deciding the best day for a picnic, the weather impacts our lives on a daily basis. Despite new techniques and technologies that allow us to forecast the weather with increasing accuracy, most of us do not realise the vast global movements and forces which result in their day-to-day weather. Storm Dunlop tells us ten things we should know about weather in its most dramatic and ordinary forms.
of the extraordinary things about our modern world is just how closely we are brought into contact with rock in everyday life. Now this might seem a little counter-intuitive. As I child, I grew up with cartoons such as The Flintstones and, a little later, sat goggle-eyed through films such as One Million Years BC. There the Stone Age protagonists acted out derring-do amid caves, craggy landscapes and erupting volcanoes.
Prey animals must constantly stay alert and rely on publicly available information to avoid being eaten, find suitable foraging and mating opportunities, and to assess local competition for resources. Reliable information allows prey to make behavioural decisions in order to ensure sufficient foraging and mating gains while reducing predation risks. However, complete information is rarely available to prey.
Humans love flowers! We admire their varied colors and shapes, enjoy the way they smell, and (especially on a day like today) give them to those we love. But why has this affection for flowers evolved in us – given that flowers have certainly not evolved to impress us? In fact, we gain very little benefit (apart from joy) from them. It is true that some flowers are edible, and that flowers may indicate where an edible part of a plant can be found
Can magicians (illusionists) really levitate themselves and others or bend spoons using only the power of their mind? No. Emphatically no. But they surely make it seem as if they can. Enjoy being fooled? Then you’ll love watching really good magic shows that allow people the opportunity to suspend their disbelief momentarily. But don’t let this suspension become permanent.
Cute and heartwarming videos of dogs fill the internet. My favourite is the bacon dog tease, but others catch my attention because they reveal extraordinary animal behaviours. For example, there are many of dogs helping other animals, like opening the back door to let in a friend. Dogs are our best animal friends, but there is a new contender. The pig might not be agile enough for Frisbees, or into making ‘guilty faces’, but like dogs, might save your life in the future.
This past December, millions of people around the world gazed in wonder at the rising of the so-called “super moon.” The moon looks super when it turns full on its closest approach to Earth, and variations in its orbit brought it nearer to us than it has been in almost 70 years. Yet even this extra super moon was scarcely bigger than a regular full moon, and few would have noticed the difference without breathless media reports that encouraged them to see it.
Deciphering the genome (the complete genetic code) of any species can lead to a wealth of knowledge. By analyzing an invasive species’ DNA, an invasion geneticist may untangle, among other things, its origin, its invasion history, and any potential hybridization with native species. These all provide vital tools when informing management efforts tackling biological invasions.
During his first official week in office, United States President Donald Trump is moving quickly on his to-do list for his first 100 days in office, proving that he plans on sticking to the promises that he made as a candidate. Earlier this week, the Trump administration ordered a media blackout at the Environmental Protection Agency and has instructed staff to temporarily suspend all new contracts and grant awards.
What are the arguments for ignoring climate change? The simplest is to deny such a thing exists. President Trump’s tweets on the topic, for instance, mostly run along the lines of “It’s record cold all over the country and world – where the hell is global warming, we need some fast!” But this is plainly at odds with the evidence, given what we know now about rising temperatures and accumulation of heat in the oceans.
In September 2015, the UK Met Office and Met Éireann (the Irish meteorological service) announced a project to give names to potentially damaging storms. The basis for naming any particular storm was the expectation that there would be major impacts on conditions over the British Isles and, in particular, of very high winds. The first storm, Abigail, brought high winds to northern Scotland and the Outer Hebrides.
John Burdon Sanderson (JBS) Haldane (1892-1964) was a leading science popularizer of the twentieth century. Sir Arthur C. Clarke described him as the most brilliant scientific popularizer of his generation. Haldane was a great scientist and polymath who contributed significantly to several sciences although he did not possess an academic degree in any branch of science.
Space may be the final frontier, but it’s not beyond the reach of today’s biologists. Scientists in all areas of biology, from tissue engineering to infectious diseases, have been using the extreme environment of space to investigate phenomena not seen on Earth. The National Aeronautics and Space Administration (NASA) has conducted research in the life sciences for almost 50 years.
