The problem of hospital infection, severe disease caused by antibiotic-resistant staphylococcus bacteria, entails major costs and great suffering. Group A streptococcus bacteria, also called meat-eating killer bacteria, are another growing problem. A team of Lund scientists in Sweden has now developed a substance called Cystapep, which seems to work on bacteria that nothing else seems to be able to knock out.
If Cystapep delivers what it promises, this is nothing short of sensational. Sweden is in a better position than other countries when it comes to antibiotic resistance, but in other parts of the world dangerous strains of bacteria have developed resistance to most of the antibiotics doctors have in their arsenal, and the problem is growing worse every year in Sweden as well.
Cystapep took its name from the fact that it is a peptide (a small molecule) that is based on a larger protein called cystatin. Cystatin occurs in various forms in the body and is part of our natural protection against bacteria, fungi, and viruses. The Lund researchers Aftab Jasir and Claes Schalén, medical microbiology, and Anders Grubb, clinical chemistry, have collaborated with a team of Polish scientists to cultivate and develop the segment of cystatin C protein that has proven to provide the best protection.

Together with their colleagues from the University of Würzburg, physicists from the group of Professor Alexander Szameit at the University of Rostock have devised a “funnel” for photons. Their discovery was recently published in the renowned journal Science and holds great promise for novel ultra-sensitive detectors as well as innovative applications in telecommunications and information processing.
The quantum-optical properties of light and its interaction with matter has fascinated the Rostock professor Alexander Szameit since College.
Researchers at the University of Zurich show that different stem cell populations are innervated in distinct ways. Innervation may therefore be crucial for proper tissue regeneration. They also demonstrate that cancer stem cells likewise establish contacts with nerves. Targeting tumour innervation could thus lead to new cancer therapies.
Stem cells can generate a variety of specific tissues and are increasingly used for clinical applications such as the replacement of bone or cartilage....
