A reversible male contraceptive, targeted to the testes with magnets
Women have several choices for long-lasting, reversible contraceptives, but most options for men are either single-use, such as condoms, or difficult to reverse, like vasectomies. Now, in a step toward a safe, long-lasting ...

Monitoring the evolution of crystal dislocations in a silicene sheet
We might imagine crystals to be perfect structures, but they are, in fact, often plagued with "defects." Curiously enough, such defects often appear due to atoms undergoing reorganization to lower the energy of the system ...

Llama 'nanobodies' could hold key to preventing deadly post-transplant infection
Scientists have developed a "nanobody"—a small fragment of a llama antibody—that is capable of chasing out human cytomegalovirus (HCMV) as it hides away from the immune system. This then enables immune cells to seek out ...
