According to quantum electrodynamics, the theory describing interactions between light and electrically charged particles, a sufficiently strong electric field can, in principle, convert some of its energy into particles and their antimatter partners. A particle's antimatter part

According to quantum electrodynamics, the theory describing interactions between light and electrically charged particles, a sufficiently strong electric field can, in principle, convert some of its energy into particles and their antimatter partners. A particle's antimatter partner has the same mass and, for electrically charged particles, the opposite electric charge.

Figuring out where cosmic neutrinos come from is tricky—radio telescopes could help find 'ghost particles' origin

Neutrinos are funny little particles that weigh almost nothing, making them one of the universe's most elusive building blocks. They can come from objects as mundane as bananas and as exotic as supernovas—the exploding death throes of massive stars. Most neutrinos stream through

Calling species 'invasive'—and culling them—isn't done lightly. But it matters to Australia's threatened species

It may sound abstract, but distinctions between "native," "introduced" or "invasive" species can often be life or death. Species considered invasive in Australia—such as European rabbits and feral pigs—are often culled, while most native animals are generally left alone.
