Genetically modified Salmonella can kill cancer cells, suggests new research published in mBio, an American Society for Microbiology. one particular strain of salmonella found to be most effective at killing cancer cells and shrinking tumors, and also not toxic.
Results from the phase 1 clinical trial of an Ebola vaccine based on the current strain of the virus suggests it is safe to use and provokes an immune response in recipients, Chinese scientists say. Until now, all tested Ebola virus vaccines have been based on the virus strain from the Zaire outbreak in 1976.
In a world first, researchers have found that a naturally occurring chemical attracts pregnant malaria transmitting mosquitoes - a discovery which could boost malaria control efforts. The chemical, cedrol, found in mosquito breeding sites near Africa's Lake Victoria, could be used in traps that would 'attract and kill' the female mosquito, preventing reproduction before she lays hundreds of eggs.
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 reappearance of tuberculosis and the rush of multidrug-resistant clinical isolates of Mycobacterium tuberculosis have reaffirmed tuberculosis as a key public health concern. Researchers from Global Homoeopathy Foundation (GHF) in collaboration with along with the Mumbai-based Haffkine Institute have developed a new homoeopathic drug for TB patients.
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.
