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.

Whether you call it effervescent, fizzy, or sparkling, carbonated water is making a comeback as a beverage. Aside from quenching thirst, researchers at the University of Illinois at Urbana-Champaign have discovered a new use for these "bubbly" concoctions that will have major impact on the manufacturer of the world's thinnest, flattest, and one most useful materials -- graphene.
As graphene's popularity grows as an advanced "wonder" material, the speed and quality at which it can be manufactured will be paramount. With that in mind,...
Physicists at the University of Bonn have managed to create optical hollows and more complex patterns into which the light of a Bose-Einstein condensate flows. The creation of such highly low-loss structures for light is a prerequisite for complex light circuits, such as for quantum information processing for a new generation of computers. The researchers are now presenting their results in the journal Nature Photonics.
Light particles (photons) occur as tiny, indivisible portions. Many thousands of these light portions can be merged to form a single super-photon if they are...
For the first time, scientists have shown that circular RNA is linked to brain function. When a RNA molecule called Cdr1as was deleted from the genome of mice, the animals had problems filtering out unnecessary information – like patients suffering from neuropsychiatric disorders.
While hundreds of circular RNAs (circRNAs) are abundant in mammalian brains, one big question has remained unanswered: What are they actually good for? In the...
An experimental small satellite has successfully collected and delivered data on a key measurement for predicting changes in Earth's climate.
The Radiometer Assessment using Vertically Aligned Nanotubes (RAVAN) CubeSat was launched into low-Earth orbit on Nov. 11, 2016, in order to test new...
A study led by scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg presents evidence of the coexistence of superconductivity and “charge-density-waves” in compounds of the poorly-studied family of bismuthates. This observation opens up new perspectives for a deeper understanding of the phenomenon of high-temperature superconductivity, a topic which is at the core of condensed matter research since more than 30 years. The paper by Nicoletti et al has been published in the PNAS.
Since the beginning of the 20th century, superconductivity had been observed in some metals at temperatures only a few degrees above the absolute zero (minus...
