The Big Bang should have created equal amounts of matter and antimatter yet good luck finding that to be so. Antimatter is instead so scarce it can be the plot of terrible Dan Brown books (and then movies) but we know it is there; PET scans (positron emission tomography) for cancer diagnosis use positrons, the antimatter particle of the electron.

Here are some surprising facts about humans’ effect on planet Earth. We have made enough concrete to create an exact replica of Earth 2mm thick. We have produced enough plastic to wrap Earth in clingfilm. We are creating “technofossils”, a new term for congealed human-made materials – plastics and concretes – that will be around for tens of millions of years.

A new study believes that football clubs which focus too much on physical attributes risk overlooking future stars. Does this mean that with the correct cognitive behavior you could outrun Usain Bolt?

Before Brexit and the US elections, Nature magazine columnist Colin Macilwain set out a challenge: “If Donald Trump were to trigger a crisis in Western democracy, scientists would need to look at their part in its downfall.”
Now that he has become president, the possibility of crisis is real, including the spectre of a “Twitter ban” for scientists. So what of scientific introspection?

Early in our careers, few of us imagined a vaccine could one day prevent cancer. Now there is a vaccine that keeps the risk of developing six Human Papillomavirus (HPV)-related cancers at bay, but adoption of it has been slow and surprising low.

Licorice is from the root of Glycyrrhiza glabra, prized for centuries because it is sweet and because of purported medical properties. Believers in traditional Chinese medicine consider it vital for the 12 regular meridians while Ayurveda claims it rejuvenates the body.

The international Genetic Investigation of Anthropometric Traits (GIANT) Consortium has uncovered 83 new DNA changes that affect human height, some rare but some adjusting height by more than 2 centimeters. The 700,000-plus-person study also found several genes pointing to previously unknown biological pathways involved in skeletal growth.
