Much of what we think we see is not real – it’s an illusion. A favourite pastime for many visual psychologists and artists is to baffle and confuse our perception by making things appear that are not really there, or manipulating the way that we might see patterns or colours. The origin of many illusions lies in the fact that the brain often receives incomplete or conflicting information.
Announced on January 13th by President Obama in his eighth and final State of the Union Address, the multi-billion dollar project will be led by US Vice President, Joe Biden, who has a vested interest in seeing new cures for cancer. Using genomics to cure cancer is being held on par with JFK’s desire in 1961 to land men on the moon.
The soils surrounding the village where I live in the north west of England have abundant fertility. They mostly formed in well-drained, clay-rich debris left behind by glaciers that retreated from the area some ten thousand years ago, and they now support lush, productive pasture, semi-natural grassland and woodland. Although the pastures are managed more intensively than they were in the past, most of them are well drained, and receive regular dressings of manure along with moderate fertiliser, and are regularly limed, which keeps the land productive and the soil in good health.
Though caused by microscopic agents, infectious diseases have played an outsized role in human history. They have shaped societies, lent us words and metaphors, and turned the tide of wars. Humans have eliminated some diseases, but others continue to plague us. In this quiz, find out if confusion is contagious or if you’re immune to the challenge.
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.
