CRISPR gene-editing advancements

This year, scientists hit a number of breakthroughs using the gene-editing technology CRISPR. Researchers in China reported modifying the DNA of a nonviable human embryo, a controversial move. Researchers at Harvard University inserted genes from a long-extinct woolly mammoth into the living cells -- in a petri dish -- of a modern elephant.

Cancer-detecting blood test

Researchers in Sweden developed a blood test that can detect cancer at an early stage from a single drop of blood. The test can accurately detect the disease 96 percent of the time and classify the type of cancer correctly 71 percent of the time.

First new antibiotic in 30 years

Early this year, scientists discovered a new antibiotic, the first in nearly 30 years, which may pave the way for a new generation of antibiotics and fight growing drug-resistance. The antibiotic, teixobactin, can treat many common bacterial infections, such as tuberculosis, septicaemia, and C. diff, and may be available in the next five years.
