If only DNA samples and microfibres made crimes as easy to solve as on CSI.
In a media world infected with misinformation and fake news, it has never been more important for scientists to talk directly to the public.
Why are there 60 minutes in an hour, and not 10? Why do we count up to 10, anyway? Quentin, age five, wants to know.
Bees and home security cameras use the same complex techniques to monitor their environments.
People universally believe scientists' solar eclipse calendars, but vaccine warnings or climate predictions are forms of science that strangely do not enjoy equivalent acceptance.
Ability expectations are what people rely upon as they seek out productive and satisfying lives. They need to be a key part of the debate over gene-editing and other major scientific breakthroughs.
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.
As much as one-third of animal species in the tropics could be eradicated if their habitats continue to be converted for monoculture farming. We can all do something to make a difference.
It's very easy to assume climate change causes droughts, but they are complex extreme events that result from a combination of drivers.
Scientists are beginning to link animal facial expressions to emotions, making it possible for us to understand how they feel.
Climate change, insects and urban farm towers are a few things that will change how and what we eat in the future.
Working with an embedded artist for a year helped one physicist realise that art and science share a lot of common ground
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.
