Isaac Newton and Albert Einstein would have bridled under today's research funding bureaucracy. It's time to allow scientists to indulge their curiosity again.
Research laboratories are dominated by men, and that's not only bad for lab culture, it can be dangerous for science.
Some people think the sky is blue because of sunlight reflected off the ocean and back into the sky. But that's not the real reason.
To conserve Earth's remarkable species, we must also defend the importance of science and scientific integrity.
Even if alien life is never discovered, all is not lost.

By 2167, genetically designed, digitally enhanced humans with Internet-connected brains will live with intelligent machines in a transformed environment and maybe even among the stars.
We will one day grow food in conditions as extreme as Mars. Developing the controlled environments required will help not only space explorers but also support our own survival here on Earth.
By 2167, DNA barcoding scans will lead to weather-style "biodiversity forecasts," enabling us to more easily protect and care for the environment.
South Africans will not see the value that science and technology adds to their daily lives until there is more interest in areas of science.
A seed contains nearly everything a tree needs to get growing. Just add a dash of water, a bit of warmth and the right location, and you'll be seeing green in no time.
Biologists have a centuries-old tradition of publishing on rare and endangered species. But poachers are using open-access information to target valuable and fragile new species.
Researchers find striking results from a large study of secondary school students.
Simon John James and Richard Bower chat about differing conceptions of what it is to travel through time.
Phrases like “knowledge production” conceal the fact that knowledge answers to something beyond itself and beyond us. To produce knowledge is to find out about something.
