Seven important facts to know about climate change
Climate expert Joseph Romm gives the facts about climate change and global warming, and what it means for us and the future of humanity.
The Hunger Games are playing on loop— And I am tired of watching
Say you wanted to take over the world—how would you do it? Let’s agree it looks much like the world we live in today, where some countries hold inordinate power over the lives of people in others; where global systematic racism, the shameful legacy of colonization and imperialism, has contrived to keep many humans poor and struggling.
Climate change – a very difficult, very simple idea
Planet Earth doesn’t have ‘a temperature’, one figure that says it all. There are oceans, landmasses, ice, the atmosphere, day and night, and seasons. Also, the temperature of Earth never gets to equilibrium: just as it’s starting to warm up on the sunny-side, the sun gets ‘turned off’; and just as it’s starting to cool down on the night-side, the sun gets ‘turned on’.
The magic of Christmas: It’s Santa’s DNA
Knowledge that we all have DNA and what this means is getting around. The informed public is well aware that our cells run on DNA software called the genome. This software is passed from parent to child, in the long line of evolutionary history that dates back billions of years – in fact, research published this year pushes back the origin of life on Earth another 300 million years.
Entering an uncharted realm of climate change
This year’s United Nations Climate Change Conference, the 21st annual session of the Conference of the Parties since the 1992 United Nations Framework Convention on Climate Change (UNFCCC) and the 11th session of the Meeting of the Parties since the 1997 Kyoto Protocol, will be held in Paris from 30 November to 11 December.
Wine and DNA profiling
In ampelographic collections, about ten living plants of each grape variety or clone are kept alive for future studies or plantings, which requires a large amount of time and money. Yet, in every collection we estimate an average of 5% of labelling errors. They can now be identified with DNA profiling and duplicates can be eliminated, thus saving time and money.
Climate change and the Paris Conference: is the UNFCCC process flawed?
As representatives from 146 countries gather in Paris for the 2015 UN Climate Change Conference, we’ve turned to our Very Short Introduction series for insight into the process, politics and topics of discussion of the conference. Is the UNFCCC process flawed?
Where did all the antihadrons go?
Describing the very ‘beginning’ of the Universe is a bit of a problem. Quite simply, none of our scientific theories are up to the task. We attempt to understand the evolution of space and time and all the mass and energy within it by applying Albert Einstein’s general theory of relativity. This theory works extraordinarily well. But when we’re dealing with objects that start to approach the infinitesimally small – elementary particles such as quarks and electrons – we need to reach for a completely different structure, called quantum theory.
The antimicrobial resistance crisis: is there a global solution?
The serendipitous discovery of penicillin by Alexander Fleming in 1929 positively transformed modern medicine. Fleming’s decision to spend his summer holiday in East Anglia and his casual approach to laboratory housekeeping was an auspicious combination. After his return to the laboratory he observed that an uncovered culture plate of Staphyloccocus bacteria had been contaminated.
What to do about whooping cough?
A century ago, pertussis, or whooping cough as it is also known, was one of those infectious diseases that most children went down with at some stage. There was a lot of suffering from the severe and prolonged bouts of coughing and many deaths occurred, especially in very young children.
The impact of On the Origin of Species
Charles Darwin was widely known as a travel writer and natural historian in the twenty years before On the Origin of Species appeared in 1859. The Voyage of the Beagle was a great popular success in the 1830s. But the radical theories developed in the Origin had been developed more or less in secret during those intervening twenty years.
The Angelina Jolie effect
It is hard to quantify the impact of ‘role-model’ celebrities on the acceptance and uptake of genetic testing and bio-literacy, but it is surely significant. Angelina Jolie is an Oscar-winning actress, Brad Pitt’s other half, mother, humanitarian, and now a “DNA celebrity”. She propelled the topic of familial breast cancer, female prophylactic surgery, and DNA testing to the fore.
Biodynamic wine
All vineyards and thus the wines they produce are not created equal. Two Chardonnays grown in neighbouring plots but with slightly differing soils, slopes and sun exposure will taste subtly different, even if both will still taste of Chardonnay too. This unique ‘somewhereness’ is what the French call terroir.
How did life on earth begin?
News broke in July 2015 that the Rosetta mission’s Philae lander had discovered 16 ‘carbon and nitrogen-rich’ organic compounds on Comet 67P/Churyumov-Gerasimenko. The news sparked renewed debates about whether the ‘prebiotic’ chemicals required for producing amino acids and nucleotides – the essential building blocks of all life forms – may have been delivered to Earth by cometary impacts.
Cars – are they a species?
The Edwardian seer and futurologist, H. G. Wells, wondered whether aircrafts would ever be used commercially. He did the calculations and found that, yes, an airplane could be built and, yes, it would fly, but he proclaimed this would never be commercial.
On the unstoppable rise of vineyard geology
The relationship between wine and the vineyard earth has long been held as very special, especially in Europe. Tradition has it that back in the Middle Ages the Burgundian monks tasted the soils in order to gauge which ones would give the best tasting wine, and over the centuries this kind of thinking was to become entrenched. The vines were manifestly taking up water from the soil.
