Sending a password or secret code over airborne radio waves like WiFi or Bluetooth means anyone can eavesdrop, making those transmissions vulnerable to hackers who can attempt to break the encrypted code. (more…)
Was haben Salamander aus den nordamerikanischen Wäldern, Insekten aus Neuseeland und Zwergtintenfische aus Thailand gemeinsam? Sie alle produzieren Klebstoffe, um sich anzuheften, zu tarnen, zu verteidigen oder um Beute zu fangen. Im Rahmen eines neuen EU-Netzwerkprojekts werden ForscherInnen mit unterschiedlichem wissenschaftlichen Hintergrund diese und andere biologische Klebstoffe unter Laborbedingungen untersuchen und ihre Ergebnisse in neue bionische Klebstoffe für nützliche Anwendungen (Wundheilung, Gewebsregeneration, Lebensmittel, Kosmetik, Holzindustrie) einfließen lassen. Das Ludwig Boltzmann Institut für Traumatologie und die Universität Wien sind die österreichischen Projektpartner. (more…)
Telling small lies desensitises our brains to the associated negative emotions and may encourage us to tell bigger lies in future, reveals new UCL research funded by Wellcome and the Center for Advanced Hindsight. (more…)
Multicolored laser light is the key to cooling these atoms to nearly absolute zero
UCLA physicists have shown that shining multicolored laser light on rubidium atoms causes them to lose energy and cool to nearly absolute zero. This result suggests that atoms fundamental to chemistry, such as hydrogen and carbon, could also be cooled using similar lasers, an outcome that would allow researchers to study the details of chemical reactions involved in medicine.

Sticky nanoparticles that deliver drugs precisely to their targets — and then stay there — could play a crucial role in fighting ovarian and uterine cancers. (more…)
Viele von uns bestrafen Normverletzungen – etwa, wenn jemand Müll auf den Bahnsteig wirft. Wenn die Normverletzung extremer wird, steigen aber auch unsere Hemmungen, etwas gegen den Verursacher zu unternehmen. Das zeigen Forscherinnen und Forscher aus Innsbruck, Abu Dhabi und Köln in einem aktuell in Nature Communications erschienenen Aufsatz. (more…)

University of Utah study listens to the natural bridge vibrate and sing
Utah’s iconic Rainbow Bridge hums with natural and man-made vibrations, according to a new University of Utah study, published September 21 in Geophysical Research Letters. The study characterizes the different ways the bridge vibrates and what frequencies and energy sources cause the rock structure to resonate. The vibrations are small, according to geology and geophysics professor Jeff Moore, but the study provides a baseline measure of the bridge’s structural integrity and shows how human activities can rattle solid rock.
