DNA robots designed in minutes instead of days

Someday, scientists believe, tiny DNA-based robots and other nanodevices will deliver medicine inside our bodies, detect the presence of deadly pathogens, and help manufacture increasingly smaller electronics.

Researchers generate human-monkey chimeric embryos

Investigators in China and the United States have injected human stem cells into primate embryos and were able to grow chimeric embryos for a significant period of time—up to 20 days. The research, despite its ethical concerns, ...

For tomato genes, one plus one doesn't always make two

Both people and tomatoes come in different shapes and sizes. That is because every individual has a unique set of genetic variations—mutations—that affect how genes act and function. Added together, millions of small ...

New technique reveals genes underlying human evolution

One of the best ways to study human evolution is by comparing us with nonhuman species that, evolutionarily speaking, are closely related to us. That closeness can help scientists narrow down precisely what makes us human, ...

Faster drug discovery through machine learning

Drugs can only work if they stick to their target proteins in the body. Assessing that stickiness is a key hurdle in the drug discovery and screening process. New research combining chemistry and machine learning could lower ...
