Evolving strains of multi-drug resistant pathogens are a growing global concern, outpacing drug discovery efforts and undermining the efficacy of existing antibiotics. The development of comprehensive diagnostics for clinical ...
What can scientists learn about human neurodegenerative disease from a major soybean pest? It's not a trick question; the answer lies in the soybean cyst nematode, one of two classes of microscopic roundworms known to lose ...
A new class of pesticides positioned to replace neonicotinoids may be just as harmful to crop-pollinating bees, researchers cautioned Wednesday.
Cells are complex, multi-compartmentalized entities of matter enclosed with a variety of membrane-bound organelles ranging from the microscale (µm) down to the nanoscale (nm) in diameter. These structures intermingle in ...
Cut off a salamander's tail and, in a few weeks, a near-perfect replacement grows. Do the same to a lizard and a new tail will regrow, but it won't be the same as the original. By comparing tail regeneration between the two ...

All humans begin life as a single cell that divides repeatedly to form two, then four, then eight cells, all the way up to the ~26 billion cells that make up a newborn. Tracing how and when those 26 billion cells arise from ...
The human genome is riddled with endogenous retroviruses—little pieces of degraded and generally harmless retrovirus DNA passed down through the generations, along with our own genetic information. Because most endogenous ...
As plants stretch toward the summer sun, they are marching toward one of the most important decisions of their lives—when to flower. Too early, and they might miss out on key pollinators. Too late, and an early frost could ...
For a small, reddish-beaked bird called the zebra finch, sexiness is color-coded. Males have beaks that range from light orange to dark red. But from a female's point of view, a male's colored bill may simply be hot, or not, ...
