New scientific evidence that may shed light on why men are more likely than women to develop aggressive forms of skin cancer has been published today in Carcinogenesis. The research carried out by scientists in UCD Conway Institute of Biomolecular & Biomedical Research shows that a gene found only in men is altered by a chemical process, which is in turn linked to aggressive forms of melanoma.
Dr William Gallagher, UCD School of Biomolecular & Biomedical Science and UCD Conway Institute has led the work of a team of researchers who are trying to identify potential biological markers that could flag aggressive forms of melanoma. Using the latest gene chip technology, their work has focused on 66 genes that undergo changes as a melanoma moves from a non-aggressive to an aggressive state. Dr Gallagher and his team have discovered that a common feature among a significant percentage of these genes is that they have been chemically altered by a process called DNA methylation.
One of these genes turned off by this process, TSPY, is located only on the male Y chromosome and, for the first time, may provide a molecular clue to the commonly held belief that men are not only more likely to develop melanoma but that it tends to be more aggressive.

More and more automobile companies are focusing on body parts made of carbon fiber reinforced plastics (CFRP). However, manufacturing and repair costs must be further reduced in order to make CFRP more economical in use. Together with the Volkswagen AG and five other partners in the project HolQueSt 3D, the Laser Zentrum Hannover e.V. (LZH) has developed laser processes for the automatic trimming, drilling and repair of three-dimensional components.
Automated manufacturing processes are the basis for ultimately establishing the series production of CFRP components. In the project HolQueSt 3D, the LZH has...
Reflecting the structure of composites found in nature and the ancient world, researchers at the University of Illinois at Urbana-Champaign have synthesized thin carbon nanotube (CNT) textiles that exhibit both high electrical conductivity and a level of toughness that is about fifty times higher than copper films, currently used in electronics.
"The structural robustness of thin metal films has significant importance for the reliable operation of smart skin and flexible electronics including...
The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.
Supermassive black holes form some of the most enigmatic phenomena in astrophysics. Their enormous energy output is supposed to be generated by the...
The probability to find a certain number of photons inside a laser pulse usually corresponds to a classical distribution of independent events, the so-called...
Microprocessors based on atomically thin materials hold the promise of the evolution of traditional processors as well as new applications in the field of flexible electronics. Now, a TU Wien research team led by Thomas Müller has made a breakthrough in this field as part of an ongoing research project.
Two-dimensional materials, or 2D materials for short, are extremely versatile, although – or often more precisely because – they are made up of just one or a...
