1. 'Miracle material' graphene is thinnest known anti-corrosion coating
   New research has established the "miracle material" called graphene as the world's thinnest known coating for protecting metals against corrosion.
2. New way to tap largest remaining treasure trove of potential new antibiotics
   Scientists are reporting use of a new technology for sifting through the world's largest remaining pool of potential antibiotics to discover two new antibiotics that work against deadly resistant microbes, including the "superbugs" known as MRSA.
3. Birds sing louder amidst the noise and structures of the urban jungle
   Sparrows, blackbirds and the great tit are all birds known to sing at a higher pitch in urban environments. It was previously believed that these birds sang at higher frequencies in order to escape the lower frequencies noises of the urban environment. Now, researchers have discovered that besides noise, the physical structure of cities also plays a role in altering the birds' songs.
4. Researchers take a step forward in transplanting pig cells to regenerate human cartilage
   Researchers have recently studied the response of human NK cells against porcine chondrocytes. The results of the research indicate that these cells, characteristic of the innate immune system, play an important role in the rejection of xenotransplantation of porcine chondrocytes.
5. Exposure to micronutrients pre-pregnancy associated with gene modifications in offspring
   The offspring of women who were given micronutrient supplements (minerals needed in small quantities, such as iron, iodine and vitamin A) before they became pregnant had gene modifications at birth as well as when they were tested at nine months.
