Quantum dot solids arranged into superstructures

Scientists have created superstructures with quantum dots, a big step toward harnessing their technological potentials. One obstacle researchers have faced while working with quantum dot solids is getting them to directly meld without adding another substance, and scientists think they’ve solved that.

Coral growth improved at Great Barrier Reef by altering seawater acidity

Coral growth improved in a section of Australia’s Great Barrier Reef after researchers lowered the seawater’s acidity there by adding an alkaline substance. The results suggest that increased carbon dioxide emissions are having a negative effect on the world’s coral reefs by raising the acidity levels of the ocean.

Squeezing embryos may indicate their viability

The viability of a human embryo can be determined by a gentle squeeze, which could have implications for in vitro fertilization. Researchers tried the technique on mice embryos and found it predicted with about 90% accuracy whether the embryo would grow successfully into viable blastocysts. They then tried it with human embryos, with the same results.
