Will they or won’t they be getting a salary increase? That’s the question on the minds of many American postdoctoral researchers who are paid less than the amount ascribed by the US Department of Labor under the Fair Labor Standards Act. Effective December 1, all employees working 40 hours or more per week were set to either earn at least $47,476 per year or be paid for overtime worked. But a November 22 court injunction help up raises for postdocs at several institutions.
Following the injunction, some institutions made good on their pledges to raise postdoc pay, while others drafted new plans. “It’s very easy for postdocs to fall through the cracks,” Gary McDowell, executive director of the advocacy group Future of Research, told The Scientist.
While institutions are directed to maintain confidentiality, a scientist accused of research misconduct frequently finds his...
Two groups recently reported on CRISPR-based, self-editing systems that can be used to track molecular events within cells. Their results were published in Science this summer (August 18) and in Nature Methods this month (December 5).
“It is a really cool technique . . . in the sense that you get one site that can generate a very diverse editing pattern and can start encoding more and more information,” said Aaron McKenna of the University of Washington who was not involved in either study.
Scientists have identified antidotes to Cas9 in bacteriophage genomes. And these proteins can block the activity of bacterial type II CRISPR-Cas systems in human cells, the team reported in Cell this month (December 8).
“The obvious interest of anti-CRISPR proteins that inhibit type II systems is the possibility to modulate the activity of Cas9 in gene-editing applications,” Philippe Horvath of DuPont in France, who was not involved in the study, wrote in an email. “The expression of these inhibiting proteins could be triggered in response to a given condition, or at a particular time point in the development of an organism, which would put a stop to the activity of Cas9. A clever way to store the molecular scalpel into its safety case.”
Researchers have identified potential functions for nearly 500 long noncoding RNAs (lncRNAs). The group’s results were published in Science last week (December 15).
“Our surprising finding is that . . . most lncRNAs function in only one cell type,” coauthor Daniel Lim of the University of California, San Francisco, told The Scientist. “This exquisite specificity in RNA function is a result that I do not think I would have believed, had we not done a study on this scale.”
