The linking of two signalling pathways in the cells of liver tumours has a clear influence on their malignancy. Activation of the platelet-derived growth factor (PDGF) messenger molecule is decisive for this linking. This results related to the development of liver cancer was generated during a current project by the Austrian Science Fund FWF and has been published in the Journal Oncogene. When the signalling pathways in liver tumour cells have been linked together, these cells develop the characteristics of cancer stem cells, which are in principal resistant to chemotherapy. This new understanding of the signalling pathways involved unlocks potential for the future development of modified therapies.

According to a new study, sexual sensation in circumcised and uncircumcised men may not be so different after all. The research consisted of genital sensory testing conducted on circumcised and uncircumcised men during states of sexual arousal and non-arousal. Results showed that no difference between the two groups was found in sensitivity to touch or pain.

Three biomedical engineers have created a genetic dimmer switch that can be used to turn on, shut off, or partially activate a gene’s function. The switch can be tuned to produce large or small quantities of protein, or none at all.

Over the last five years, large, predatory Humboldt squid have moved north from equatorial waters and invaded the sea off Central California, where they may be decimating populations of Pacific hake, an important commercial fish. Ironically, these squid may have benefited from the decline of large tuna and billfish in the Equatorial Pacific, which previously preyed upon and competed with the Humboldt squid for food.

A New Scientist article about a study by scientists at the institute of Arctic and Alpine Research of the University of Colorado, Boulder, has bad news for coastal areas around the world.
The team, led by Mark F. Meier, suggests that the latest International Panel on Climate Change projection of sea level rise in the 21st century by is too low by 10-25 centimeters because it leaves out the contributions of increasing glacier melt water.
