Medical Potential for Sequencing Fetal DNA in Mother's Bloodstream
Sequencing the fetal DNA that circulates in a pregnant woman’s blood holds promise for modern genomic medicine, suggests a new review article. Fetal DNA sequencing improves the accuracy of prenatal screening tests for genetic conditions and at times has led to the diagnosis of maternal conditions that may have otherwise gone undetected.

Global Soil Microbiome Survey Reveals Bacteria-Fungi War
Soil is full of life, essential for nutrient cycling and carbon storage. To better understand how it functions, an international research team conducted the first global study of bacteria and fungi in soil. Their results show that bacteria and fungi are in constant competition for nutrients and produce an arsenal of antibiotics to gain an advantage over one another.

Mitochondrial Genome of Malaria Mosquito is Sequenced
A research team has sequenced and annotated the first complete mitochondrial genome of Anopheles funestus, one of the main vectors of malaria in sub-Saharan Africa. This milestone offers information that researchers might eventually exploit to develop new ways to prevent this deadly disease.

DNA Repair After CRISPR Not What We Thought
Despite high hopes and high investment in CRISPR-Cas9 gene editing, scientists still have a lot to learn about how it works in humans. In the latest example, University of California, Berkeley, scientists found that people’s assumptions about how cells repair the genome after the Cas9 enzyme snips DNA are wrong.

Treating Ovarian Cancers by Targeting Mutations
New research has shown that ovarian cancer patients with a tumor mutation in the BRAF gene respond exceptionally well to treatment with targeted drugs, known as BRAF inhibitors.

Do Bacteria Ever Go Extinct? Absolutely!
Contrary to previous thinking, new research shows that bacteria go extinct at substantial rates, although appear to avoid the mass extinctions that have hit larger forms of life on Earth.

Previously Unclassified Shape is Key to Efficient Cell Packing
When scientists started modeling the geometric conformations that cells use to pack themselves efficiently into epitheliums and other tissues, they expected to see columnar or bottle-like shapes. Instead, they found a whole new shape previously unknown to science; the scutoid.
