A group of scientists has created a new gene therapy designed to help patients who lost their vision due to a hereditary disease - Leber congenital amberosis. The therapy can restore vision to the point where a person can navigate in a maze in dim light, The Deccan Chronicle reports.

As The Daily Mail notes, the risk of another heart attack, stroke and premature death is reduced by approximately 25% in people taking statins (cholesterol-lowering drugs) after a stroke or heart attack. A new study carried out by scientists from the United States has made such conclusions.

A brand new brain implant has been designed by experts from the University of Southern California. It stimulates the brain region associated with learning ability and memory. Thanks to the implant, experiment participants began to cope with the task for memory much better, The Daily Mail reports.

As The Deccan Chronicle notes, scientists from the University of Chicago have found out how HIV spreads throughout the body. Probably, the discovery of the scientists may lead to the development of new drugs for HIV infection. According to the scientists, when the cell infected, HIV makes the cell to form a small capsule with the virus from its membrane.

According to rough estimates, 30% to 40% of cancer patients undergoing chemotherapy, experience neurologic disorder such as peripheral neuropathy. It is characterized by tingling, numbness, weakness and pain in the hands and feet as usual. A new drug can prevent cancer patients from this disorder, Zee News reports.

People with atrial fibrillation who take anticoagulants (drugs preventing the blood clots formation) rarely experience the dementia. This conclusion was made by scientists of the Karolinsky Institute. The scientists have analyzed the data of 444106 people from Sweden for 2006-2014. Participants had atrial fibrillation, which increases the risk of stroke.

Scientists from the University of Surrey have presented nanoparticles that can be heated to a high temperature and can destroy cancer cells. In addition, these nanoparticles independently regulate their temperature and cool down, in order to prevent the damage of healthy tissues.

The team of scientists has found why the blood enzyme dipeptidylpeptidase-4 (DPP4) concentration is increased in diabetics. Perhaps the discovery of the scientists will lead to the development of new methods of treating diabetes, Zee News reports.

A study was carried out on genetically modified mice. The scientists have revealed that the skin can affect the pressure and heart rate when the level of oxygen in the environment changes. As we know, due to lack of oxygen, the blood flow to the heart increases. This process is partially regulated by specific proteins - hypoxia induced factors (HIFs), Business Standard reports.

As we know, premature birth is dangerous for the brain. Now the level of development of the brain in infants born prematurely can be assessed by means of electroencephalography (EEG) and artificial intelligence. According to Zee News, the method was developed by scientists from the University of Helsinki.
