2016 is here. The New Year is a time for renewal and resolution. It is also a time for dieting. Peak enrolment and attendance times at gyms occur after sumptuous holiday indulgences in December and again when beach wear is cracked out of cold storage in summer. As the obesity epidemic reaches across the globe we need new solutions. We need better ways to live healthy lifestyles.
As the days get shorter, the Netherlands, a low lying waterlogged country, becomes a safe haven for approximately five million waders, gulls, ducks, and geese, which spend the winter here resting and foraging in fresh water lakes, wetlands, and along rivers. Many of these birds travel to the Netherlands from their breeding ranges in the Arctic.
When heads of state and other leaders of 195 nations reached a landmark accord at the recent United Nations COP21 conference on climate change in Paris, they focused primarily on sea level rise, droughts, loss of biodiversity, and ways to decrease greenhouse gas emissions in order to reduce these consequences. But arguably the most serious and widespread impacts of climate change are those that are hazardous to the health of people.
Every winter the child inside us hopes for snow. It brings with it the potential for days off work and school, the chance to make snowmen, create snow angels, and have snowball fights with anyone that might happen to walk past. But as the snow falls have you ever wondered how it is formed? What goes on in the clouds high above our heads to make these snowflakes come to life?
Do mountains matter? Today, 11 December, is International Mountain Day, celebrated worldwide since 2003. The fact that the UN General Assembly has designated such a day would suggest a simple answer. Yes – and particularly for the 915 million people who live in the mountain areas that cover 22 percent of the land area of our planet.
Government funding of science has become an increasingly prominent issue in the United States. Examining the current debate and its consequences, Social Problems editor Arne L. Kalleberg interviews Gordon Gauchat about his recent article “The Political Context of Science in the United States: Public Acceptance of Evidence-Based Policy and Science Funding.”
Climate expert Joseph Romm gives the facts about climate change and global warming, and what it means for us and the future of humanity.
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.
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’.
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.
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.
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.
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?
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 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.
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.
