Antimatter Captured!

Scientists at Europe's best particle-physics laboratory have been able to trap a very small amount of antihydrogen—the simplest type of anti-atom—for the first time.

In reality, no one has ever been able to drop an anti-apple and watch it fall down (or up), and the antimatter produced in particle colliders is so energetic that it is hard to examine with the tools of precision physics. For decades, physicists at CERN and elsewhere have been trying to overcome these limitations with antihydrogen, which consists of a single positron orbiting a single antiproton. By shining laser light onto hydrogen or antihydrogen and observing which wavelengths are absorbed, the energy levels of the two can be compared in detail. And since hydrogen is electrically neutral, it should be possible to observe gravity’s tiny tug on it without the confounding effects of electrostatic attraction to other particles.

Surprising Science
  • China's Chang'e 4 lunar lander touched down on the far side of the moon on January 3.
  • In addition to a lunar rover, the lander carried a biosphere experiment that contains five sets of plants and some insects.
  • The experiment is designed to test how astronauts might someday grow plants in space to sustain long-term settlements.

Love in a time of migrants: on rethinking arranged marriages

Arranged marriages and Western romantic practices have more in common than we might think.

Culture & Religion

In his book In Praise of Love (2009), the French communist philosopher Alain Badiou attacks the notion of 'risk-free love', which he sees written in the commercial language of dating services that promise their customers 'love, without falling in love'.
