Cancer researcher Guy Ungerechts has succeeded for the first time in reprogramming the measles virus from a vaccine strain so that it attacks cancer cells. The virus recognises receptors that are particularly common among cancer cells.
Taking vitamin C as a preventative measure doesn’t protect against colds – but it does lessen some of the symptoms if you already have the sniffles. Comparative studies carried out on physically fit sportsmen show that taking the vitamin daily has a small protective effect.
There are two opposing effects at play here: on the one hand a pinch of salt raises the boiling temperature of the water by between one and two degrees. That means it needs more energy and time to boil. On the other hand, salt also increases its capacity for warmth retention.
Windowpanes, washing machines or bridges – all of these objects will vibrate if disturbed by an external stimulus. This is known as natural resonant frequency. Every piece of material has one, and for glass it lies between 200 and 2,000 vibrations per second.
Scientists, including a team from the University of Sheffield, have found a new way to protect passengers by protecting the plane itself. The ‘FlyBag’ is a bombproof membrane designed to line the plane’s hold.
The 20th and 21st century saw some of the most deadly virus pandemics. The Spanish flu was particularly devastating. From 1918 it killed more than 25 million people – some experts believe the figure may even be closer to 50 million.
