The topical anti-fungal drug Ciclopirox causes HIV-infected cells to commit suicide by jamming up the cells’ powerhouse, the mitochondria — according to a study by researchers at Rutgers Biomedical and Health Sciences. And unlike current anti-HIV drugs, Ciclopirox completely eradicates infectious HIV from cell cultures, with no rebound of virus when the drug is stopped. The study has been published in the journal PLOS ONE.
The treatment of patients with HIV has been revolutionized by the advent of combination anti-retroviral drugs. But although these drugs are highly effective at keeping HIV at bay, they must be taken for the life of the patient and never eliminate the infection completely. This is illustrated by the often rapid resurgence of virus in patients who stop taking these medications. The persistence of HIV is partially due to the ability of the virus to disable the cell’s altruistic suicide pathway, which is normally activated when a cell becomes infected or damaged.

NASA is currently working on the first practical field test toward the possibility of faster than light travel.
Traveling faster than light has always been attributed to science fiction, but that all changed when Harold White and his team at NASA started to work on and tweak the Alcubierre Drive. Special relativity may hold true, but to travel faster or at the speed of light we might not need a craft that can travel at that speed. The solution might be to place a craft within a space that is moving faster than the speed of light! Therefore the craft itself does not have to travel at the speed of light from it’s own type of propulsion system.
It’s hard to imagine something so simple could save a child’s life. But that’s exactly what this small device built on 3-D printer did. University of Michigan doctors designed and implanted the tracheal splint inside Kaiba Gionfriddo, now 20 months old.
The tiny collar was made to treat Kaiba’s tracheobronchomalacia, a condition where the airways collapse when breathing or coughing. It was created directly from a CT scan of the collapsed area using a laser-based 3-D printer. The printer created the splint using polycaprolactone, a biodegradable polyester that is slowly absorbed by the body over a few years. It was sewn around the airway to keep it open and give support so more tissue could grow.
The doctors described their groundbreaking treatment in New England Journal of Medicine letter published on May 23.
Just a reminder: we live in the future. An amazing future.
