Films trick our senses in many ways. Most fundamentally, there’s the illusion of motion as “moving pictures” don’t really move at all. Static images shown at a rate of 24 frames per second can give the semblance of motion. Slower frame rates tend to make movements appear choppy or jittery. But film advancing at about 24 frames per second gives us a sufficient impression of fluid motion.

We humans have a love-hate relationship with bugs. I’m not talking about insects — although many of us cringe at the thought of them too — but rather the bugs we can’t see, the ones that make us sick. Sure, microorganisms give us beer, wine, cheese, and yoghurt; hardly a day goes by without most people consuming food or drink produced by microbial fermentation.

In pondering how rapidly animal, plant, microbial, viral, and human genetic and regulatory sequences travel around the world over wireless and fiber optic networks, I’m transported back to the sci-fi movie The Fly I watched as a boy. Released in 1958, the film was based on a story George Langelaan published in Playboy.

Visual illusions, such as the rabbit-duck (shown below) and café wall are fascinating because they remind us of the discrepancy between perception and reality. But our knowledge of such illusions has been largely limited to studying humans.

Slow lorises are enigmatic nocturnal primates that are notoriously difficult to find in the wild. The five species of slow loris that have been evaluated by the International Union for the Conservation of Nature’s Red List of Threatened Species are classified as threatened or critically endangered with extinction. So, how did one end up recently on the set of Lady Gaga’s music video?

It is a safe bet that the name of Pierre Rolland rings very few bells among the British public. In 2012, Rolland, riding for Team Europcar finished in eighth place in the overall final classifications of the Tour de France whilst Sir Bradley Wiggins has since become a household name following his fantastic achievement of being the first British person ever to win the most famous cycle race in the world.

Coral reefs are the most diverse ecosystem in the sea. In some ways they are very robust marine ecosystems, but in other ways, perhaps because of their huge numbers of species, they are very delicate and susceptible to being damaged or killed. On the one hand, healthy reefs are glorious riots of life, and marine scientists have spent several decades unravelling the complicated ways in which they work. On the other hand, at least one third of the world’s reefs have already died – gone for ever in terms of human lifetimes at least – even when the cause of their demise is lifted.

For tigers, visiting your neighbor is just not as easy as it used to be. Centuries ago, tigers roamed freely across the landscape from India to Indonesia and even as far north as Russia. Today, tigers inhabit is just 7% of that historical range. And that 7% is distributed in tiny patches across thousands of kilometers.

There is a pressing need to re-establish a cultural narrative for science. At present we lack a public understanding of the purpose of this deeply human endeavour to understand the natural world. In debate around scientific issues, and even in the education and presentation of science itself, we tend to overemphasise the most recent findings, and project a culture of expertise.

In the reality-based community outside of Washington D.C. there is a growing fear and increasing disbelief about the failure to take climate change seriously. Many who once put their faith in science and reason have come to the depressing conclusion that we will only take action if nature slaps us silly; they increasingly see hurricanes and droughts as the only hope.

Rapid development of molecular genetics in recent decades has revolutionized our understanding of life and the natural world. Scientists in the 1970s suggested that the grey wolf might be the sole ancestor of domestic dogs, but it was only in 1997 that Carles Vilà, Peter Savolainen, Robert Wayne, and their co-authors provided the conclusive evidence on this based on the analysis of molecular genetic markers.

Every year since I can remember, I find myself in England’s famous book town for the excellent Hay Festival. Now in its 27th year the eponymous book festival can be found nestling under canvass for 11 days in the Black Mountains of the Brecon Beacons National Park.

In recent decades, the extraordinarily rapid disappearance of frogs, toads, and salamanders has grabbed the attention of both the scientific community and concerned citizens the world over. Although the causes of some of these losses remain unresolved, the novel disease chytridiomycosis caused by the skin-based fungus Batrachochytrium dendrobatidis (Bd), has been identified as the causative agent in many of the declines and extinctions worldwide.

I would like to suggest that as we, as responsible citizens, observe Arbor Day 2014, we also begin looking at forests as more than simply numerous trees growing in stands. Rather, we need to look at forests as ecosystems that are not only important in and of themselves, but also provide essential functions—so-called ecosystem services—to sustain the quality of human life.

The small picture is the big picture and biologists keep missing it. The diversity and functioning of animals and plants has been the meat and potatoes of most natural historians since Aristotle, and we continue to neglect the vast microbial majority.

The 1960s are famous for many reasons: the civil rights movement, the first moon walk, the Cuban missile crisis, rock and roll. The 1960s were also a period when awareness of environmental degradation spread to society at large.
