Stressed-DNA repair protein identified | KurzweilAI - 0 views

  •  
    Vera Gorbunova and Andrei Seluanov of the University of Rochester have found that human cells undergoing oxidative stress caused by environmental chemicals or routine cellular processes produce a protein (SIRT6) that stimulates cells to repair DNA double-strand breaks, thought to be associated with premature aging and cancer. The team first measured levels of SIRT6 in stressed cells, then treated a second group of stressed cells with a drug that deactivates the protein. DNA repair in the second group stopped, confirming SIRT6′s role.  The team also found that SIRT6 acts in concert with another protein, called PARP1, to make the repairs. Furthermore, the team found that increased levels of SIRT6 lead to faster DNA repair. They suspect that the protein acts as a "master regulator," coordinating stress and DNA repair activities.

People who really identify with their car drive more aggressively, study finds - 0 views

  •  
    The studies found:People who perceive their car as a reflection of their self-identity are more likely to behave aggressively on the road and break the law.People with compulsive tendencies are more likely to drive aggressively with disregard for potential consequences.Increased materialism, or the importance of one's possessions, is linked to increased aggressive driving tendencies.Young people who are in the early stages of forming their self-identity might feel the need to show off their car and driving skills more than others. They may also be overconfident and underestimate the risks involved in reckless driving.Those who admit to aggressive driving also admit to engaging in more incidents of breaking the law.A sense of being under time and pressure leads to more aggressive driving.

The BBC Trust Report on Science | through the looking glass - 0 views

  • Aside from questions over appropriateness of expertise being a rather slippery issue, there is very little information given about the expertise of a speaker. We found lot of reliance on phrases such as ‘scientists have found’ and ‘experts say’. Personally I think we need to address this issue before we can even get on to matters of whether experts are the right ones or not. Although expertise may be implied through editing, and TV in particular can flag up institutional association and title, we rarely saw a contributor’s disciplinary background specified. Especially significant I thought, in broadcast reports about new research we found little explicit reference to whether or not a particular contributor was involved in the research being reported (online reports often refer to someone as ‘lead author’ or ‘co-author’). This lack of definition makes it hard for audiences to judge a contributor’s independence, whether they are speaking on a topic they have studied in depth or if they are simply working from anecdote.
