Research finds effects go beyond increase in aggression
COLUMBUS, Ohio – Playing violent video games not only increases aggression, it also leads to less self-control and more cheating, a new study finds.
Researchers found that teens who played violent video games ate more chocolate and were more likely to steal raffle tickets in a lab experiment than were teens who played nonviolent games. (more…)
Berkeley Lab Study Reveals Origins of an Exotic Phase of Matter
Understanding superconductivity – whereby certain materials can conduct electricity without any loss of energy – has proved to be one of the most persistent problems in modern physics. Scientists have struggled for decades to develop a cohesive theory of superconductivity, largely spurred by the game-changing prospect of creating a superconductor that works at room temperature, but it has proved to be a tremendous tangle of complex physics.(more…)
Steuergeschenke und Tiefstzinsen sollen Unternehmen zum Investieren bringen. Das schaffe Arbeitsplätze. Unsinn.
Die Bevölkerung soll schlucken, dass Unternehmen nur wenig Steuern zahlen und diese im nationalen und internationalen «Steuerwettbewerb» erst noch optimieren, beziehungsweise vermeiden können. Und die Bevölkerung soll schlucken, dass sie auf ihrem Gesparten keine Zinsen mehr bekommt, selbst wenn sie es brav und sicher auf Sparkonten anlegt.
Denn tiefe Steuern und tiefe Zinsen sollen es den Unternehmen ermöglichen, grosse Gewinne zu machen und mit diesen viel zu investieren, also neue Maschinen zu kaufen, neue Produktionsstätten zu eröffnen oder Dienstleistungsbetriebe auszubauen. Dank solcher Investitionen entstünden viele neue Arbeitsplätze. Das Schaffen von Arbeitsplätzen ist das angebliche Ziel der Steuergeschenke und Tiefstzinsen. (more…)
UD faculty members discuss 2013 prize-winners at annual symposium
Today’s chemists might work at a computer as often as in a laboratory, medical researchers studying conditions such as diabetes rely on understanding how cells carry and deposit materials within the body, and average investors in the market increasingly buy index funds to average out the short-term ups and downs of individual stocks.(more…)
NABU begrüßt die Rückkehr des großen Beutegreifers
Der erste Nachweis eines Wolfs in Thüringen ist nun bestätigt. Videoaufnahmen zeigen einen Wolf südlich von Jena. Das wildbiologische Büro Lupus und das Thüringer Umweltministerium bestätigen den Bildnachweis. Es wird nicht der erste Wolf sein, der durch Thüringen zieht. Wichtig ist es jetzt, keine Panik zu verbreiten. (more…)
NASA’s Curiosity Mars rover has passed the milestone of 100,000 shots fired by its laser. It uses the laser as one way to check which chemical elements are in rocks and soils. (more…)
In yeast at least, the aging process appears to reduce an organism’s ability to silence certain genes that need to be silenced. Now researchers at Brown University who study the biology of aging have shown that the loss of genetic control occurs in fruit flies as well. Results appear online in the journal Aging.(more…)
Berkeley Researchers Develop Technique For Imaging Individual Carbon Nanotubes
Despite their almost incomprehensibly small size – a diameter about one ten-thousandth the thickness of a human hair – single-walled carbon nanotubes come in a plethora of different “species,” each with its own structure and unique combination of electronic and optical properties. Characterizing the structure and properties of an individual carbon nanotube has involved a lot of guesswork – until now.
Researchers with the U.S. Department of Energy (DOE)’s Lawrence Berkeley National Laboratory (Berkeley Lab) and the University of California (UC) Berkeley have developed a technique that can be used to identify the structure of an individual carbon nanotube and characterize its electronic and optical properties in a functional device.
