The Lancet: Scientists announce final trial results of the world’s most advanced malaria vaccine

The first malaria vaccine candidate (RTS,S/AS01) to reach phase 3 clinical testing is partially effective against clinical disease in young African children up to 4 years after vaccination, according to final trial data, published in The Lancet. The results suggest that the vaccine could prevent a substantial number of cases of clinical malaria, especially in areas of high transmission. The findings reveal that vaccine efficacy against clinical and severe malaria was better in children than in young infants, but waned over time in both groups. However, protection was prolonged by a booster dose, increasing the average number of cases prevented in both children and young infants.malaria vaccines

New material for creating artificial blood vessels

Blocked blood vessels can quickly become dangerous. It is often necessary to replace a blood vessel — either by another vessel taken from the body or even by artificial vascular prostheses. Together, Vienna University of Technology and Vienna Medical University have developed artificial blood vessels made from a special elastomer material, which has excellent mechanical properties. Over time, these artificial blood vessels are replaced by endogenous material. At the end of this restorative process, a natural, fully functional vessel is once again in place. The method has already been used successfully in rats. Arteriosclerotic vascular disorders are one of the most common causes of death in industrialized countries.

Scientists create the sensation of invisibility

The power of invisibility has long fascinated man and inspired the works of many great authors and philosophers. In a study from Sweden’s Karolinska Institutet, a team of neuroscientists now reports a perceptual illusion of having an invisible body, and show that the feeling of invisibility changes our physical stress response in challenging social situations. The history of literature features many well-known narrations of invisibility and its effect on the human mind, such as the myth of Gyges’ ring in Plato’s dialogue The Republic and the science fiction novel
