Dublin City University (DCU) researchers, Neill Costigan, PhD student at DCU and funded by the Irish Research Council for Science, Engineering and Technology (IRCSET) and Prof Michael Scott member of the Science Foundation Ireland (SFI)-funded Shannon Institute of Cryptography, have successfully cracked a crypto system published thirty years ago by coding theorist Robert J McEliece.
The crack which was accomplished using resources at the SFI-Funded Irish Centre for High End Computing was announced at the Post-Quantum Cryptography conference in Cincinnati, USA on Saturday 18 October.
NASA's Mars Reconnaissance Orbiter has observed a new category of minerals spread across large regions of Mars. This discovery suggests that liquid water remained on the planet's surface a billion years later than scientists believed, and it played an important role in shaping the planet's surface and possibly hosting life.
Researchers examining data from the orbiter's Compact Reconnaissance Imaging Spectrometer for Mars have found evidence of hydrated silica, commonly known as opal. The hydrated, or water-containing, mineral deposits are telltale signs of where and when water was present on ancient Mars.
Last winter, the thickness of sea ice in large parts of the Arctic fell by nearly half a metre (19 per cent) compared with the average thickness of the previous five winters. This followed the dramatic 2007 summer low when Arctic ice extent dropped to its lowest level since records began.
Up until last winter, the thickness of Arctic sea ice showed a slow downward trend during the previous five winters, but after the summer 2007 record low extent, the thickness of the ice also nose-dived. What is concerning is that sea ice is not just receding but it is also thinning.
Children and adolescents who abuse alcohol or are sexually active are more likely to take methamphetamines (MA), also known as ‘meth’ or ‘speed’. Research published today in the open access journal BMC Pediatrics reveals the risk factors associated with MA use, in both low-risk children (those who don’t take drugs) and high-risk children (those who have taken other drugs or who have ever attended juvenile detention centres).
Applying electrical stimulation to the scalp and the underlying motor regions of the brain could make you more skilled at delicate tasks. Research published today in the open access journal BMC Neuroscience shows that a non-invasive brain-stimulation technique, transcranial direct current stimulation (tDCS), is able to improve the use of a person’s non-dominant hand.
Did the Bible's King David and his son Solomon control the copper industry in present-day southern Jordan? The possibility is raised once again by research reported in the Proceedings of the National Academy of Sciences.
