Washington D.C., Aug .10 - A study says that a molecular switch that flips between different versions of genes could be crucial for maintaining stem cells across all animals from simple flatworms to humans.
The study at Center for Genomic Regulation says that flatworms (also known as planarians) have an incredible capacity for self-renewal, with almost any part of their body able to regenerate a whole new worm in a matter of days.
The researchers found that they 'mix and match' certain parts of their genes in particular ways - a process known as alternative splicing. The same analysis of flatworm cells that had changed into more specific cell types revealed a different mixture of gene parts.
Washington D.C., Aug .10 - A new study says that people prefer passing on the responsibility, when faced with choices that affect others, than when those decisions affect only themselves.
A series of experiments by Mary Steffel from Northeastern University and her collaborators found that these findings were particularly true when those choices had potentially negative consequences.
In domains as diverse as making a business decision, choosing a hotel, ordering meals, and even participating in experiments, people were two or three times as likely to delegate an unappealing choice on behalf of someone else than one on their own behalf.
Participants in one experiment imagined that they or their bosses needed a hotel reservation for an upcoming business trip.
Washington, Aug 10 : US Republican presidential nominee Donald Trump said on Tuesday he had no plan to change his temperament as he was grappling with his sagging poll numbers following recent feud with a family of a fallen Muslim American soldier and leaders within his own party.
"I think that my temperament has gotten me here," Xinhua cited Trump as saying in an interview with Fox Business Network.
"I have always had a good temperament and it's gotten me here. We beat a lot of people in the primaries and now we have one person left, and we're actually doing pretty well there, but we'll see how it all comes out," he added.
Washington, Aug 10 : Since the end of the political primaries in June, the campaign of Republican presidential nominee Donald Trump has spent absolutely nothing on television advertisements, the media reported on Wednesday.

The billionaire's austerity calls attention to his unpopularity in the polls, where Clinton has a wide lead, and his fundraising efforts and donations in July, when he collected more than $80 million.
Washington D.C., Aug. 9 - Putting up at retirement homes limits older adults' rights to sexual freedom because of a lack of policies regarding the issue and the actions of staff and administrators at these facilities.
According to a Georgia State University study, though assisted-living facilities emphasize independence and autonomy, the staff and administrators behave in ways that create an environment of surveillance.
This indicates conflict between autonomy and the protection of residents in regard to sexual freedom in assisted-living facilities.
Regulations at these facilities may vary, but they share a mission of providing a home-like environment that emphasizes consumer choice, autonomy, privacy and control.
