The so-called Suess effect in radiocarbon (14C) has been known for decades. Geological sources of carbon like coal and oil, that formed many millions of years ago, long since lost their radiocarbon through radioactive decay – they contain 14C-free “dead” carbon. From the mid-19th century the radiocarbon activity of the atmosphere declined as dead carbon from fossil fuels was dug out of the ground and burnt producing carbon dioxide (CO2) in the atmosphere.
Islands urgently require major additional conservation efforts. Many species face extinction, natural areas are small and fragmented and alien species dominate most ecosystems.
When asked to think about the ocean, most people imagine a pristine habitat in the tropics with golden sands and clear blue waters, or the diversity of fish associated with coral reef communities.
World Environment Day is celebrated on 5 June to encourage positive environmental action. Instituted by the United Nations in 1974, it provides a global platform for public outreach in promoting the importance of the protection of our environment.
In science, perhaps the most famous recent award is for the prediction of the existence of the Higgs Boson particle, discovered at CERN’s Large Hadron Collider. Overall, the most famous recipient ever is likely Marie Curie. She went down in history as the first person to win two. She took Nobel Prizes in 1903 and 1911 for getting radium and polonium out of pitchblende, with her own elbow power.
When the Earth is viewed from space, it’s mostly blue. In fact, the ocean covers over 70% of our planet. Life began in the world’s oceans, and today – billions of years later – we’re no less dependent on it. From the diverse organisms which call it home, to the complex ways it helps keep global climates in check, our own survival is undeniably linked to that of the ocean.
I guess the funniest thing I ever saw was a person driving down the highway in a Toyota Prius smoking a cigarette with the windows closed. It was like they were telling me, “I respect your atmosphere but not mine.” That got me thinking, does human generated, gaseous, atmospheric pollution actually make up a significant part of the total atmosphere, and can it possibly affect it?
World Turtle Day is celebrated on 23 May every year since its inception in 2000. In honour of these grandiose creatures, we have compiled a reading list of biology titles and articles that have helped to further research into the conservation biology of all chelonians.
How can realism in science be defined? Philosophers, historians, and the general public, have always related it to a philosophical doctrine or a technological effect. However, there is a type of realism — very widespread in science — that has gone unnoticed among scholars: the realist attitude of social and cultural origins. Behind this attitude lie commercial and engineering interests.
Charles Darwin’s five year voyage aboard H. M. S. Beagle and subsequent life work are as widely known as any events in the history of the biological sciences. His wide ranging bird work has been overshadowed by drab small birds he discovered in the Galapagos Islands–the Galapagos, or Darwin’s, finches.
But this question of conscience goes beyond science. There is one clear axis along which we are all asked to act in life – in favour of ‘self’ or ‘society’. Do we always do what is best when it comes to deciding the balance? In all pursuits there is an innate tension between the interests of self and society. This tension has existed as long as we’ve had human society of any complexity.
In these days of Zika, Chikungunya, Dengue, and Ebola pandemics, and with the devastating smallpox, influenza, and polio epidemics of the 20th century still fresh in our collective memories, it seems counterintuitive to consider the possibility that viruses will ever be regarded other than with fear and loathing. However, if trials currently underway in Europe, Australia, and the US prove successful, then we may eventually reach a point where certain viruses are viewed with approval and even a degree of affection.
Dinosaurs, literally meaning ‘terrible lizards’, were first recognized by science, and named by Sir Richard Owen (who preferred the translation ‘fearfully great’), in the 1840’s. In the intervening 170 years our knowledge of dinosaurs, including whether they all really died out 65 million years ago, has changed dramatically. Take a crash course on the history of the dinosaurs with our infographic.
Massive Open Online Courses (MOOCs) burst into the public consciousness in 2012 after feverish press reports about elite US universities offering free courses, through the Internet, to hundreds of thousands of people worldwide. A Massachusetts Institute of Technology (MIT) course on Circuits and Electronics that had attracted 155,000 registrations was a typical example. Pundits proclaimed a revolution in higher education and numerous universities, fearful of being left behind, joined a rush to offer MOOCs.
The 2016 World Malaria Report estimates that there were approximately 215 million cases of malaria and 438,000 deaths in 2015. The majority of deaths occur in sub-Saharan Africa and among young children, and malaria remains endemic in around 100 countries with over three billion people at risk. Over the past 15 years there have been major gains in reducing the global burden of malaria
Earth Day is an annual celebration, championed by the Earth Day Network, which focuses on promoting environmental protection around the world. The Earth Day Network’s mission is to build a healthy, sustainable environment, address climate change, and protect the Earth for future generations. The theme for Earth Day 2016 is Trees for the Earth, raising awareness around protecting the Earth’s forests.
