CRISPR Editing Stops HIV Virus in Infected Cells
Human immunodeficiency virus-1 (HIV-1) infection is a chronic disease affecting more than 35 million people worldwide. The infection can be controlled by antiretroviral therapy (ART), but there is still no complete cure. Now, a new study targeting the regulatory genes of the virus using CRISPR/Cas9 has helped block the production of the virus by infected cells.

Genetics Help Make a Weed a Weed
A study has has found that the success of weedy and invasive plants like the Jerusalem artichoke lies in their genes. Understanding how invasive plants evolve and the genes that enable them to thrive in a new environment is key to better understanding why they are wreaking havoc on natural landscapes and food production around the world.

Study Could Spawn Better Ways to Combat Crop-Killing Fungus
Rice blast, the staple’s most damaging fungal disease, destroys enough rice to feed 60 million people annually. A study examining this fungus's evolution into a pathogen could may help lead to different ways to fight or prevent crop and plant diseases, such as new fungicides and more effective quarantines.

Cellular Valve Structure Opens Up Potential Novel Therapies
Biochemists have determined the detailed structure of a volume-regulated chloride channel. This cellular valve is activated in response to swelling to prevent the cell from bursting. The protein also plays an important role in the uptake of chemotherapeutics and the release of neurotransmitters after a stroke. The controlled regulation of its activity thus opens up a promising strategy for novel therapies.

Algorithm Predicts Life Expectancy After Heart Attack
A new algorithm developed by UCLA researchers more accurately predicts which people will survive heart failure, and for how long, whether or not they receive a heart transplant. The algorithm would allow doctors to make more personalized assessments of people who are awaiting heart transplants, which in turn could enable health care providers to make better use of limited life-saving resources and potentially reduce health care costs.
