Scientists are doing pretty well in Europe - so why did so many turn out for the worldwide March for Science? What are Europeans protesting, exactly - and why? DW heads to Amsterdam and other European capitals to find out.

NTDs are diseases that science can cure and eliminate, and an international summit is taking place in Geneva to help make that happen. The task is truly gargantuan, and we're not there yet, but it's already been one of the most successful and impressive fights staged by the international community.

It's all about artificial intelligence - the rise of our machine overlords. What's going to happen? When's it going to happen? Or has it already happened? We're going to delve into these and - a number of other questions - with some of the most progressive minds out there.

Is walking barefoot the secret to a better life? We promise you the slime of your life when we take a look at harvesting snail slime. What do caterpillars, bees and plastic bags have in common – tune in to find out about one very hungry caterpillar that might help solve the world's plastic bag problem. All that and more on Spectrum with host Jessie Wingard.

According to research conducted in Switzerland, Sweden and Germany, spiders eat more meat each year than humans do, and they could easily eat the human race each year - more than once!

A supercomputer to fill in gaps in data, technology to assist the aging Japanese, harvesting snail slime and alien trees in Cameroon.

Germany's chancellor, Angela Merkel, officially opens the country's sparkling neurodegenerative research center - and DW's there look at how scientists are addressing one of the greatest medical threats in a generation.

Murders, suicides, mass shootings: more people die as a result of guns in the US than in any other high-income country. Scientists say their research into gun violence would help reduce the number of deaths, if it was properly funded. Also on the program: radioactive wild boars in the Czech Republic, and being woken up by an electric shock.
