Our ability to find and share information today is potentially limitless. But how did we get here? From cave paintings to the iPad—how does human innovation bring us here?
Diplomats and activists from around the world are meeting in Rio de Janeiro to talk about how the planet’s growing population can live better lives without damaging the environment. The Rio+20 meeting marks the 20th anniversary of the United Nations Earth Summit in Rio, a watershed meeting to address topics as diverse as climate change…
International talks to address human-caused global warming began 20 years ago in Rio de Janeiro. But despite attempts to curb emissions of the greenhouse gases responsible, they have continued to pour into the atmosphere since then. Last year was no exception. In 2011, the burning of fossil fuels, as well as other activities such as…
UK researchers have developed a porous material that can preferentially soak up CO2 from the atmosphere. NOTT-202 is a “metal-organic framework” that works like a sponge, absorbing a number of gases at high pressures. But as the pressure is reduced, CO2 is retained as other gases are released. The development, reported in Nature Materials, holds…
So many scientific studies are making incorrect claims that a new service has sprung up to fact-check reported findings by repeating the experiments. A year-old California, company, Science Exchange, announced its “Reproducibility Initiative,” aimed at improving the trustworthiness of published papers. Scientists who want to validate their findings will be able to apply to the…
The rate of star formation in the universe has dropped to just 3% of its long-ago peak, and there’s no end in sight to the decline, a new study finds. A team of astronomers has determined that the rate of star birth peaked around 11 billion years ago, just 2.7 billion years after the Big…
Until this week climate change was sadly absent from the presidential election discourse, even though scientific reports have linked the increasingly extreme events experienced recently in the US and elsewhere – the drought and heatwaves, deluges and blizzards that some call “weather weirding” – to systemic change rather than coincidental natural fluctuations. Sandy has forced…
