Tale of two trees: New web tool estimates gene trees with ease

Gene trees, much like family trees, trace the lineage of a particular gene from its deep ancestral roots to its still-growing branches. By comparing gene trees to species trees, which map the evolutionary history of species, ...

What makes vertebrates special? We can learn from lancelets

Scientists once thought that humans must have 2 million genes to account for all our complexity. But since sequencing the human genome, researchers have learned that humans only have about 19,000 to 25,000 genes—not many ...

The slower they turn, the brighter they glow

With Halloween over, ghostly decorations are now being replaced by Christmas themed ornaments, many of which glow in the dark. This glow, termed luminescence, is produced by chemical and biochemical reactions or when electrons ...

How stretchy fluids react to wavy surfaces

Viscoelastic fluids are everywhere, whether racing through your veins or through 1,300 kilometers of pipe in the Trans-Alaska Pipeline. Unlike Newtonian fluids, such as oil or water, viscoelastic fluids stretch like a sticky ...

Asian catfish genome decoded

The striped catfish Pangasianodon hypophthalmus makes its home in the legendary Mekong River, the longest river in Southeast Asia and largest inland fishery in the world. Vietnam stands as the leading producer of the species, ...

Perovskite solar cells leap toward commercialization

Solar energy has long been considered the most sustainable option for replacing our dependence on fossil fuels, but technologies for converting solar energy into electricity must be both efficient and inexpensive.
