Australian researchers have developed a new genome editing technology that can target and kill blood cancer cells with high accuracy. Using the technology, researchers from the Walter and Eliza Hall Institute were able to kill human lymphoma cells by locating and deleting an essential gene for cancer cell survival.

The Ebola virus circulating in humans in West Africa is undergoing relatively few mutations, none of which suggest that it is becoming more severe or transmissible, according to a National Institutes of Health study in Science. The study compares virus sequencing data from samples taken from patients in Guinea (March 2014), Sierra Leone (June 2014) and Mali (November 2014).

Scientists have discovered the hiding place of HIV in cells, an advance that may lead to new therapies to combat the deadly virus. Researchers at the International Center for Genetic Engineering and Biotechnology (ICGEB) in Italy have photographed the structure of nucleic lymphocytes with a high-resolution microscopy technique to discover the "hiding place" of HIV.

Scientists have identified the first-ever evidence of a human population uniquely adapted to tolerate the toxic chemical arsenic in the Andes Mountains of Argentina. A Swedish research team led by Karolinska Institutet and Uppsala University professor Karin Broberg, performed a genome wide survey from a group of 124 Andean women screened for the ability to metabolise arsenic (measured by levels in the urine).

Scientists have for the first time found that an abnormal protein whose accumulation in the brain is a hallmark of Alzheimer's disease starts building up inside neurons of people as young as 20. It has long been known that amyloid accumulates and forms clumps of plaque outside neurons in ageing adults and in Alzheimer's but this is the first time amyloid accumulation has been shown in such young human brains, researchers said.

Two of the four known groups of human AIDS viruses originated in western lowland gorillas in Cameroon, according to a new study. An international team of scientists from the Perelman School of Medicine at the University of Pennsylvania, the University of Montpellier, the University of Edinburgh, and colleagues conducted a comprehensive survey of simian immunodeficiency virus (SIV) infection in African gorillas.

Scientists have successfully developed healthy cartilage from embryonic stem cells, a breakthrough that could help treat arthritis patients.
