Flipping the Drake Equation for a deep time perspective on the Fermi Paradox

by gdw in FictionalFieldwork

Is anybody out there? Where are all the alien civilizations? Even if (intelligent) life is very unlikely, the sheer size and age of the universe means that even long odds might have produced space faring civilizations. Yet, so far, nada. When people are considering the (im)probability of non-human space travellers, one thing always comes up: […]... Read more »

Human sacrifice, inequality, and cycles of political power

by gdw in FictionalFieldwork

Human sacrifice to preserve inequality Statistically speaking (wait, wait, don’t click away, I know this is not the most enticing opening, but bear with me), you and me, we are not part of the 1%, or the 0.01%, that in most Western societies holds a disproportionate amount of influence and resources. Secretly, though, we want […]... Read more »

Rewriting life: Adding letters to the ABC of DNA

by gdw in FictionalFieldwork

(Also appeared on United Academics.) The alphabet of life The grand tale of life is long and complicated. Storylines intertwine and many subplots twist and turn unexpectedly. Amazingly, this billion-year-spanning story is written in an alphabet that contains only four letters, the alphabet of DNA. A for adenine, C for cytosine, G for guanine, and […]... Read more »

Once upon a time… On the origin of fairy tales

by gdw in FictionalFieldwork

(Also appeared on United Academics Magazine) Once upon a time, around 6 000 years ago, there lived a blacksmith. This blacksmith was a true craftsman, always looking for ways to improve his metal-moulding skills. When he had practised all he could, he saw only one way towards perfection: a demonic deal. So he called forth […]... Read more »

Life Below Zero Degrees

by GDW in The Beast, the Bard and the Bot

What do you do when you’re looking for life? Well, while there are a lot of new ideas and discoveries lately, expanding the limits of where we know life can occur, an often used phrase is ‘follow the water’. But what if that water’s frozen? Recently, bacteria from the Antarctic permafrost (aka Planococcus halocryophilus strain […]... Read more »

Cheating Your Way to Extinction

by GDW in The Beast, the Bard and the Bot

For a long time, it has been thought that evolutionary and ecological research were quite separated from each other. After all, evolution takes place on long timescales while ecological events usually happen much faster. At least, that was the common perception. Lately, however, it has become clear that, in some cases, the relevant timescales in […]... Read more »

The (Lack of) Changes in Ecological Research

by GDW in The Beast, the Bard and the Bot

Ecology is a rapidly changing, dynamic field of research. In recent decades, there’s been a major shift from considering ecosystems as stable and poised to seeing them as systems that are in constant flux. At least, that’s what ecologists want (us) to believe. But how much of this claimed change has been able to seep [...]... Read more »

Publish and Perish: Aspects of Science Fraud

by GDW in The Beast, the Bard and the Bot

If you want to make it in the academic world, you better publish. A lot. Preferably in so-called high-impact journals. Otherwise, no job and no funding (or the other way around). Hence the use of the phrase ‘publish or perish’ to capture the enormous importance of generating sufficient publications in sufficiently respectable journals. And most [...]... Read more »

Predicting Technological Progress: Putting Moore’s Law to the Test

by GDW in The Beast, the Bard and the Bot

Being able to predict the pace of technological development could be quite useful for a lot of people. No surprise then, that several models (or ‘laws’) have been posited that aim to describe how technological progress will unfurl (the most famous one probably being Moore’s law, for those interested: original article here). However, these laws [...]... Read more »

Body Size and Life Span, or Big Dogs Die Soon(er)

by GDW in The Beast, the Bard and the Bot

When looking at mammals in general, being big correlates quite well with living long lives (barring disease, being eaten and things of that nature, of course). But, within species, it seems that the bigger individuals live less long than their smaller conspecifics. What could be going on here? And what better species to study this [...]... Read more »

Studying Human Evolution. In Mice.

by GDW in The Beast, the Bard and the Bot

The evolutionary history of humanity isn’t the easiest tale to tell. As time passed, we, unlike other primates, spread across the globe, colonizing the various lands we explored. All these different habitats were surely characterized by diverging sets of selection pressures. Lo and behold, there arose diversity among human beings. But finding the exact genetic [...]...

Fighting Disease with Biodiversity

by GDW in The Beast, the Bard and the Bot

Biodiversity is, in most cases, good. And, as I’ve written before, biodiversity matters. In general, a healthy dose of biodiversity is something to strive for. It can, as a recent study in Nature shows, even help fighting disease. (Warning: modest bullet point bonanza below.) The researchers performed their investigation on three levels: First, sampling ‘in [...]... Read more »

The Subglacial Saga Continues…

by GDW in The Beast, the Bard and the Bot

Cold… Darkness… … And life. Sure, microbial life, but life nonetheless. Lake Whillans, part of the Whillans Ice Stream, to be found at the West Antarctic Ice Sheet, has been reached and sampled a little less than two weeks ago. Now, researchers of the WISSARD team report the presence of microscopic life in the samples. [...]... Read more »

New Species, Born in Conflict?

by GDW in The Beast, the Bard and the Bot

The ancient and mysterious Greek philosopher Heraclitus once purportedly said that war is the father of all things. Now, a recent article in Trends in Ecology and Evolution presents a new perspective on the phrase. The genome, that collection of genes representing the hereditary information of an organism might seem like quite a peaceful place. [...]... Read more »

Safe for Consumption: Genetically Engineered Food

by GDW in The Beast, the Bard and the Bot

Imagine crops that need less pesticides because they possess an inherent resistance to certain bugs. Imagine crops that can thrive in our changing climate, or produce extra vitamins. Or grow faster. Now stop imagining. Growing knowledge of genetics and development of molecular techniques enables us to produce such crops. In fact, genetically engineered food crops [...]... Read more »

‘Social Chromosome’ in Ants

by GDW in The Beast, the Bard and the Bot

A lot of ant species are very social. So social in fact that they’re called ‘eusocial’. But, even though the common conception involves a single queen leading her tightly organized colony, many social systems are possible. Even within a single species. For example, in the red fire ant Solenopsis invicta two different social organizations are [...]... Read more »

Malthus, Darwin, and the (Sustainable?) Future of Humanity

by GDW in The Beast, the Bard and the Bot

In 1798, Thomas Robert Malthus, a British scholar, published (anonymously at first) An Essay on the Principle of Population. In this highly influential work on population dynamics, he noted that “the increase of population is necessarily limited by the means of subsistence.”. Put simply, a population can’t keep growing, as the resources it needs are [...]... Read more »

Alzheimer’s Disease in Space

by GDW in The Beast, the Bard and the Bot

Space travel. Few things speak more to the imagination than the possibility of leaving our ‘pale blue dot’ and exploring the vast universe in which we’re only a speck of dust. But, making a journey to the stars or planets is not the safest endeavor. There are obvious matters such as accidents, computer failures and [...]... Read more »

Crowdfunding Science

by GDW in The Beast, the Bard and the Bot

Scientific research costs money. And in times where the economy isn’t exactly booming, it’s an area where, wrongfully I believe, budget cuts are quite likely to occur. When austerity reigns, governments and funding agencies alike allocate less and less capital to scientific research. Time to consider alternative routes of funding. One of these relies on [...]...
