Harvard University uncovers DNA switch that controls genes for whole-body regeneration
Some animals can achieve extraordinary feats of repair, such as salamanders which grow back legs, or geckos which can shed their tails to escape predators and then form new ones in just two months.
Planarian worms, jellyfish, and sea anemones go even further, actually regenerating their entire bodies after being cut in half.
Now scientists have discovered that that in worms, a section of non-coding or ‘junk’ DNA controls the activation of a ‘master control gene’ called early growth response (EGR) which acts like a power switch, turning regeneration on or off.
“We were able to decrease the activity of this gene and we found that if you don't have EGR, nothing happens," said Dr Mansi Srivastava, Assistant Professor of Organismic and Evolutionary Biology at Harvard University.
“The animals just can't regenerate. All those downstream genes won't turn on, so the other switches don't work, and the whole house goes dark, basically.”
The studies were done in three-banded panther worms. Scientists found that during regeneration the tightly-packed DNA in their cells, starts to unfold, allowing new areas to...

PREVIOUSLY DEPORTED CHILD RAPIST RE-ARRESTED IN TEXAS
The morning of March 7, 2019, Border Patrol Agents working along the border near the Paso Del Norte Port of Entry arrested a man identified as 40-year-old Santos Quinilla-Tum. He was traveling with his 17-year-old daughter, also taken into custody. The Border Patrol said the father and daughter are both from Guatemala.
Agents reviewed records and learned about Quinilla’s prior criminal history and deportation. Quinilla was arrested on March 22, 2005 in Massachusetts and charged with Rape of Child with Force, a felony. Quinilla was later found guilty and sentenced to 18 months in prison. Quinilla was subsequently deported to Guatemala in 2009.
Quinilla will be facing prosecution for the felony of reentering the U.S. illegally after a deportation, officials said.

Southern Poverty Law Center Fires Founder Morris Dees, Suggests Misconduct
“Effective yesterday, Morris Dees’ employment at the Southern Poverty Law Center (SPLC) was terminated. As a civil rights organization, the SPLC is committed to ensuring that the conduct of our staff reflects the mission of the organization and the values we hope to instill in the world,” SPLC president Richard Cohen said in a statement. When one of our own fails to meet those standards, no matter his or her role in the organization, we take it seriously and must take appropriate action.”
“Today we announced a number of immediate, concrete next steps we’re taking, including bringing in an outside organization to conduct a comprehensive assessment of our internal climate and workplace practices, to ensure that our talented staff is working in the environment that they deserve – one in which all voices are heard and all staff members are respected,” he added.
According to the Montgomery Advertiser, Dees’ biography no longer appears on the Montgomery-based organization’s website.
ALReporter’s Josh Moon, citing multiple sources, said Dees faces allegations of sexual harassment.
The SPLC fired Morris Dees yesterday and announced it today. Multiple sources have told me that the allegations of inappropriate conduct involve sexual harassment incidents. Multiple incidents that have come to light after an initial recent allegation.
134 people are talking about this
In a statement to the Associated Press, Dees said his dismissal involved a personnel issue and called the SPLC a “wonderful” organization. He said he wishes the organization luck.
Dees, a Montgomery-based lawyer, co-founded the SPLC in 1971. Tax records show in 2017 that the organization had $450 million in assets.
The development comes as observers say the organization’s credibility has eroded, in part, due to its overzealous adding of conservatives groups and right-leaning figures to its “hate list.” A recent Washington Post opinion-editorial criticized the SPLC for a series of recent “blunders,” which included its failed attempt to label House and Urban Development Secretary Ben Carson and author Maajid Nawaz as “extremists.”
For decades, the hate list was a golden seal of disapproval, considered nonpartisan enough to be heeded by government agencies, police departments, corporations and journalists. But in recent years, as the list has swept up an increasing number of conservative activists — mostly in the anti-LGBT, anti-immigrant and anti-Muslim categories — those conservatives have been fighting back. Boykin, of the FRC, recently sent a letter to about 100 media outlets (including The Washington Post) and corporate donors on behalf of four dozen groups and individuals “who have been targeted, defamed, or otherwise harmed” by the SPLC, warning that the hate list is no longer to be trusted. Mathew Staver, chairman of the Christian legal advocacy group Liberty Counsel, told me 60 organizations are interested in suing the SPLC.
…
Along the way, the SPLC undermined its own credibility with a couple of blunders. In 2015, it apologized for listing Ben Carson as an extremist (though not on the hate list), saying the characterization was inaccurate. Then, this past June, the group paid $3.4 million to Muslim activist Maajid Nawaz and his Quilliam organization to settle a threatened lawsuit.
According to a June 2018 report, more than 60 groups have weighed legal action against the SPLC for branding them as “hate groups” after Nawaz successful sued the organization. In February, Vice co-founder Gavin McInnes sued the SPLC, accusing the organization of “defaming” him by publishing “false, damaging and defamatory” information in an attempt to...
