One Mind: Looking at genetics and environment – The Knox Student

Like any aspect of medicine or biology, mental health is quite a complex subject and there isnt really any one thing that can improve or worsen it. In most cases, genetics is a key factor. A lot of mental conditions, or even just mental health issues in general, tend to be rather common in some families. Obviously, genetics is a complex subject, and family history can only explain so much of it. For instance, Down Syndrome, one of the most common mental health conditions, is caused by an abnormality in the number of chromosomes a person has. Schizophrenia has been traced to one very specific gene. Autism, on the other hand, is largely genetic, but has been linked to hundreds, perhaps even thousands of genes, and there isnt one or even a specific set of these genes that seem to cause it.

Confused yet? Believe me, it gets weirder. Many of these autism genes have been traced to pre-evolution, meaning that humans have had them before they were human. The number of autistic genes has since increased. This, combined with a possible occurrence of a few of these genes in child prodigies, has led some to believe that autism was a positive mutation for humanity at some point and played a small role in species survival. Also, even though autism is highly genetic and can run in families family members almost never have the same autistic symptoms, nor do they fall on the same place on the spectrum.

Schizophrenia is just as complex and surprising. For instance, that one gene that has been linked to Schizophrenia has been named DIS (Disrupted in Schizophrenia). The reason for this is because scientists still have no idea what the gene is supposed to do. They only know that its malfunction results in Schizophrenia. Another weird statistic is that Schizophrenia seems to be slightly more common in gay men than most other groups, and the scientific community still has no idea why.

Perhaps strangest of all is that despite all of this genetic complexity, the mentally ill and those with physical disabilities are still a minority population-wise. The mentally ill make up only about one-fifth of the American populace. Most people are able-bodied and neurotypical despite literally thousands of interconnected parts designed to fit together in one specific way. One of my personal favorite biology facts is that evolution functions on genetic diversity. Literally every creature that exists today does so because somebody was born different from everyone else, and, miracle of miracles, that individual had an easier go at life than all the others, and so that became the new normal. Take us, for example. We have opposable thumbs, are mostly hairless, walk on two feet, stand up straight, live in communities, etc., and the basic reason for all of it? Well it worked for that first guy.

Arbiters of Change: The new pro-life generation – Great Falls Tribune – Great Falls Tribune

Lauren Rhoda, president of the Saints for Life club at Carroll College, outlines her thoughts on the pro-life movement. "I think a cultural focus shift towards loving life and celebrating it will help a lot of other things fall into place," she said. TRIBUNE VIDEO/JULIA MOSS

Lauren Rhoda doesnt back down from her beliefs.

She is a modern crusader for the pro-life movement and lives a life devoted to maintaining the ideals of the cause.

But Rhoda is not an abortion-focused protester picketing outside clinics. She is not angry. Rhoda does not admonish or judge women who get abortions. In fact, she loves them unequivocally.

Lauren Rhoda is not your fathers pro-life advocate.

Lauren Rhoda believes that pro-life is about the whole life. Its about the whole person and making sure that everyone knows they are cared for and loved. (Photo: TRIBUNE PHOTO/JULIA MOSS)

The entirety of the 22-year-old Carroll College students belief system is rooted in science, from her activism for life to her Catholic faith. The Colorado-native brings an unwavering smile and brightness to her efforts.

She is a human sunflower sowing Helena in positive energy and love.

Rhoda is a chemistry major and the president of the Saints for Life club. She leads the group in activities that promote its mission statement: to protect and advocate for life from conception to natural death.

This entails spending hours offering support and prayer outside the local Planned Parenthood, but also includes volunteering with the elderly at the nursing center, hosting human-trafficking awareness and prayer vigils and advocating for the environment.

Its not just about abortion, Rhoda said. How can we advocate for a pro-life ethic if we are not loving those and caring for those that are already alive and already with us and suffering among us?

Through their association with the national Students for Life of America group, Rhoda and her fellow club members hosted an informational immigration display earlier in the semester to give Carroll students the opportunity to read through and understand President Donald Trumps immigration policies and what they mean.

The Saints for Life provided students tools to write letters to their state representatives to speak out against the immigration plan if they chose to do so. More than 150 letters were written in three hours.

Saints for Life member Marko Prizmic said some students were apprehensive about the motives of the display after realizing who was hosting it.

When the group attended the Womens March on Jan. 21, Prizmic said the group was largely met with support. However, a limited few still brandished their middle fingers as they passed by.

The group attributes it to a misunderstanding of its cause.

Pro-life is often associated with staunch religion and the more conservative side of the political spectrum, but Rhoda said the true essence of the movement doesnt assign itself to a specific party or faith, and the rest of the Saints for Life agree.

Saints for Life members, left to right, Cordell Andersen, Mary Leslie, Lauren Rhoda and Marko Prizmic meet to discuss club positions at Carroll College on March 23. Saints for Life focuses on abortion, but tackles a host of other pro-life topics, including environmental issues and immigration. Were consistent all the way through across issues Prizmic said. We carry over the idea of dignity for everyone. Theres a focus on abortion because it affects so many. (Photo: TRIBUNE PHOTO/JULIA MOSS)

Were consistent all the way through across issues, Prizmic said. We carry over the idea of dignity for everyone. Theres a focus on abortion because it affects so many.

That can make the voting booth a difficult place.

We dont take a purely conservative stance, and we dont take a liberal stance either, Rhoda said. We live in a country where the political climate is very hot right now, unfortunately. I believe that our country was founded on the principles laid out in the Declaration of Independence life, liberty and the pursuit of happiness. Principle among these is life, so I do very much vote with that in mind.

Rhodas love for life in all of its stages is genuine, and she beams as she talks about her Saturdays spent in the local nursing home, the Rocky Mountain Care Center. Every weekend, she visits the older women to hang out, talk to them, be there for them and paint their nails.

Its just one of the most wonderful things in the world, Rhoda said. One time I was painting this elderly womans nails, her name is Agnes, and she leaned in and gave me a kiss on the forehead. It was so sweet, and I mean thats why we do what we do. Pro-life is about the whole life, and its about the whole person and making sure everyone is cared for and loved and knows that.

Though Rhodas focus isnt solely concentrated on abortion, that facet of the movement is still what brought her into the fold. She remembers having an epiphany in high school that changed her life.

I was taking this biology class of all things, AP biology, and it was in public school, Rhoda said. We were studying embryology and I realized that, biologically speaking, life begins at conception when that sperm meets that egg so I realized there is this inconsistency in the way I was thinking. I couldnt deny these embryos life because they technically were certainly alive in the biological sense.

Her new-found belief system didnt jump the gap from pro-choice to pro-life, instead Rhoda said she lived her life with a barrier between her and the issue of abortion. She was never for it, but figured it wasnt her business, and so she didnt think about it.

Rhoda said she has always been passionate about advocating for the marginalized, and her personal scientific breakthrough brought the most basic form of human life into her main area of focus. She said this is when she committed herself to being pro-life and began to learn more and more about what that would mean for her.

Like most things in her life, Rhoda said it meant continuing her pro-science ethic.

Biologically speaking, life begins at conception, she continued; there is not a more solid point to define the start of life.

Rhoda poses several questions about the issue.

What constitutes a living, human? Is it the environment in the womb versus out? Is it at 40 weeks? What about babies who gestate past their due date? Is it when they have brain waves? That doesnt happen at the exact same time for all babies. Is a baby defined as less of a person because it is developing slower?

It makes it too arbitrary, Rhoda said. The most definite line we can use is just the moment of conception.

Rhoda speaks in absolutes. Life begins at conception. Abortion is the killing of an unborn child. There are no gray areas.

But love and compassion should prevail. There are no gray areas there either.

She assesses women who opt to abort not as bad people, but as people in difficult situations who deserve comfort and support. Rhoda wants to meet scared, unsure pregnant women where theyre at and offer them comfort and alternatives. Should a woman decide to go ahead with an abortion, Rhoda said it is then even more critical to be there for her, help her heal and not look down on her for the decision she has made.

I wish, in an ideal world, that it wasnt thinkable, Rhoda said. I wish for people to never feel that pressure. Maybe their immediate gut reaction is, Oh no, Im 16, and Im pregnant. How am I going to do this? I think it would be really empowering to let women know that they can do it and there are more options. There needs to be a societal reform wherein mothers are embraced and supported by the community.

As she sits in a monthly Saints for Life meeting, she and her friends demolish a few pizzas and talk about whats going on in their lives. They discuss inspiring pro-life lectures theyve attended and opportunities to learn more about the cause and what they can do.

Rhoda is not alone in her all-encompassing love for life. She is merely one face in the new pro-life generation.

We want to create an environment where abortion is not needed, Prizmic said. We need to give support so that she doesnt need to make that choice. We need to take care of her and respect her. I will never know what shes going through, but I know I love her.

Through their charity and demeanor, the group is actively changing the pro-life movement.

I know in the 80s, they would bar doors, bomb clinics, kill doctors thats not pro-life, Prizmic said. That part is small now, but it still exists.

Mary Leslie, another Saints for Life member, nods in agreement. Though she isnt a Carroll student, she still jokes that she goes to Carroll because she technically is going there ... for the pro-life club meetings.

The answer to violence isnt more violence, Leslie said.

There is a lingering distrust of pro-life advocates who stand outside Planned Parenthood, despite the good intent of the Saints for Life.

Sometimes theyre kind, but its obvious theyre told not to talk to us, Leslie said. They know well be there, and theyre told not to respond. But some do ask questions. We let them know that no matter what, its OK and theyre still loved.

She, too, is a joyful human with a big smile and love to spare. Leslie finds encouragement through her faith, but said her involvement in the pro-life movement has nothing to do with religion.

Even if I walked away from the church, Id still be pro-life, Leslie said.

Though Rhoda does hang out in pro-life circles, she has several pro-choice friends and believes each side has a lot to learn from the other.

Though she is in disagreement with their stance, Rhoda said she can empathize with the passion her pro-choice friends have in supported a womans right to choose and ardent belief that she cannot be told what to do with her own body.

That is something, Rhoda said. Thats true. You cant force someone to do something. You can just hope that theyll want to and you have to make it possible for that to happen and make room for that to happen.

Rhoda always goes back to love and support.

She has a friend back in Colorado who was sexually assaulted and became pregnant as a result. Her friend chose to keep the child, though it was a difficult decision. Rhoda said she was there for her throughout the decision, to comfort her.

Similarly, if I had a friend who chose to have an abortion, itd be my job to support her and love her, not necessarily support the abortion, but say Im here for you no matter what, Rhoda said. Thats all you can do. An especially if she has an abortion, shell probably be hurting after that.

Rhoda is ready to make allowances for unsure pregnant women who are grappling with this heavy decision.

But dont forget, Rhoda is anti-abortion. She supports all women, but she is vehemently against the organization seemingly synonymous with abortion: Planned Parenthood.

Her seemingly permanent smile quickly drops. She sits forward in her seat. Her words lose their softness and become sharp.

I think Planned Parenthood is a fundamentally corrupt organization, Rhoda said.

She cites Margaret Sanger, the founder of Planned Parenthood, and her involvement in the eugenics movement of the 1900s and the convoluted argument that the birth control clinics were part of a larger racist agenda.

There is no question that Sanger was a eugenicist but several studies into her writings have refuted the idea that she was trying to weed out the black population. However, this idea has remained a prevalent talking point for many pro-life organizations.

In 2001, Herman Cain, a Republican from Georgia who made a run for the presidency, said Sanger started Planned Parenthood, the objective was to put these centers in primarily black communities so they could help kill black babies before they came into the world.

Then, in 2015, Ben Carson, now the U.S. Secretary of Housing and Urban Development, said Sanger believed people like me should be eliminated, or kept under control. He later clarified that people like me referred to the black population.

Much of this claim comes from a Dec. 10, 1939, letter penned to Clarence Gamble by Sanger in which she said, We do not want word to go out that we want to exterminate the Negro population and the minister is the man who can straighten out that idea if it ever occurs to any of their more rebellious members."

However, the sentence is often taken out of context. The rest of the correspondence indicates Sanger was saying she didnt want misinformation to go out. Instead, Sanger was developing a public health venture, called the Negro Project, for underprivileged black communities.

But this point is still heavily contested by anti-abortion advocates.

Anti-abortion lawmaker wants voters to define person

I dont think anything good can come from an organization like that, Rhoda said. I also believe theyve been caught in a few lies, and thats important to focus on. Such as when they were selling parts of aborted fetuses or such as when they claim to offer mammograms, and they actually dont.

Rhoda said, in her eyes, the good they do doesnt outweigh the bad, and there are other low-income options for men and women.

I believe that the funds being allocated toward Planned Parenthood ought to be allocated more toward the federally qualified health care centers, Rhoda said. And yes, while I agree that they do offer health care services if you knew that your dry cleaner, for instance, they were actually running a meth lab in the back, should you still support them?

Rhoda is soft, but she is strong. She knows what she believes and she sticks to it.

In late January, she traveled to San Francisco to participate in the Walk for Life. Reminiscing on the experience coaxes her signature smile back out. As she talks about the walk, her mind is back in California.

She was surprised by the diversity of those in attendance. She held her I am the pro-life generation sign and marched with the young and the old of different creeds and races. The flip-side of her poster had the same message, but in Spanish.

Yo soy la generacion provida.

I thought it was just amazing to see everyone coming together to support this and to advocate for the most vulnerable among those who dont have a voice, Rhoda said. It was just a really joyful gathering in the midst of San Francisco overall it was just, it was a very joyful experience.

She beams.

The camaraderie, the love, the support thats what its all about for Rhoda. That is what it means to be pro-life to her.

I hope that for all the pro-life people in the movement that it comes from a place of love and just caring, she said.

WOBURN, Mass.--(BUSINESS WIRE)--

Frequency Therapeutics, a company developing a pipeline of new drugs that activate progenitor cells within the body and restore healthy tissue, today announced the expansion of its management team with the promotion of Raj Manchanda, Ph.D. to Chief Development Officer and the appointment of Steven Dworetzky, Ph.D., to Senior Vice President of Molecular and Cell Biology. Dr. Dworetzky brings over 27 years of experience in key research and development roles to Frequency and will be working closely with senior leadership on scientific strategy and program development.

Frequency continues to rapidly advance our Progenitor Cell Activation (PCA) platform with a lead program addressing hearing loss. I am very pleased to have a proven scientist and businessman like Steven lead the Frequency team in our Farmington, CT location, said David Lucchino, President, CEO and Co-founder of Frequency. I am also honored to announce the well-deserved promotion of Raj to Chief Development Officer. Rajs leadership has been critical in transforming Frequency to a highly efficient development stage organization since joining us from Biogen.

Raj Manchanda, Ph.D., has been promoted to Chief Development Officer from his prior role as the Senior Vice President of Pharmaceutical Development and Technical Operations. He will continue to spearhead development activities including formulation and analytical development, manufacturing and non-clinical safety studies to facilitate clinical trials and broaden Frequencys drug development pipeline. Raj joined Frequency in 2016 from Biogen where he held a series of leadership positions, most recently as Vice President of Neurodegeneration. While at Biogen, he led the CMC development for approval and commercialization for Tecfidera, the leading oral therapy for MS. Before Biogen, held key R&D positions at Avid Radiopharmaceuticals (acquired by Eli Lilly), PerkinElmer, and Diatide (acquired by Schering AG). During his 20 years in the pharmaceutical industry, he has worked on over 25 INDs and 6 NDAs, including two Fast Track programs. Raj holds a Ph.D. in Chemistry from Yale University and was the Anna Fuller Postdoctoral Fellow at MIT.

Steven Dworetzky, Ph.D. joins Frequency as Senior Vice President of Molecular and Cell Biology Research. Dr. Dworetzky rose to the level of Senior Principal Scientist in the Neuroscience department at Bristol-Myers Squibb, with experience leading interdisciplinary programs to the clinic. Stevens ion channels team was responsible for bringing multiple compounds into clinical study. Post BMS and prior to joining Frequency, Steven was Chief Scientific Officer and Senior Vice President of Discovery Research at Knopp Biosciences. While there, he implemented a fully integrated drug discovery team for ALS and other neurology indications, as well as new directions in hematopoiesis studies. Steven received his Bachelors degree in Biology and Chemistry from Skidmore College and his Ph.D. in Molecular and Cellular Biology from the University of Florida in Gainesville.

Frequencys PCA platform presents outstanding opportunities for the development of new medicines in indications with high unmet medical needs, said Dr. Dworetzky. I look forward to lending my experience and expertise to continue the work started by Bob Langer and Jeff Karp, and bolstering the Company goals in driving the next wave of regenerative medicine.

ABOUTPROGENITOR CELL ACTIVATION (PCA) Frequencys precise and controlled approach transiently causes Lgr5+ progenitor cells to divide and differentiate, much like what is seen in naturally regenerating tissues such as the skin and intestine. Frequency activates stemness through mimicking signals provided by neighboring cells (the stem cell niche) with small molecules, and this proprietary approach is known as the Progenitor Cell Activation (PCA) platform. Frequency believes that PCA has the potential to yield a whole new category of disease-modifying therapeutics for a wide range of degenerative conditions. To fuel its drug discovery programs, Frequency is leveraging a PCA screening platform using primary human cells, including cochlear progenitor cells and adult human progenitor cells from the GI tract. Frequencys initial focus is on chronic noise induced hearing loss. Other potential applications include skin disorders, gastrointestinal diseases and diabetes.

Marquette scientists discover the early stages of neurodegenerative diseases MC1 GR2 – Marquette Wire

Share on Facebook

Share via Email

Marquette biologists and mathematicians are using bakers yeast to understand the early stages of neurodegenerative diseases such as Alzehimers and Parkinsons.

Dr. Anita Manogaran, an assistant professor of biological sciences, and her lab are studying the impact of basic cell biology on neurodegeneration. By understanding what goes on in a single cell, Manogarans lab was able to gain insight into the bigger picture of neurodegenerative diseases. Many neurodegenerative diseases involve misfolded proteins, or molecules sticking together and making shapes they arent supposed to. The lab used bakers yeast to observe how certain proteins misfold in individual cells.

We are doing something unorthodox by studying proteins in bakers yeast, Manogaran said. We are able to get a lot of information really fast when we use bakers yeast.

The lab utilized 4-D live cell imaging to observe how the proteins misfold in the cell in order to learn more about these early stages of formation.

Brett Wisniewski, a research technician in Manogarans lab, believes that using yeast and other simple organisms will always be an excellent starting point for understanding the most complex human diseases.

Neurodegenerative diseases are common in older patients, but this new discovery by Manogarans lab found proteins associated with these diseases misfold in the brain years before symptoms occur. Manogaran hopes this discovery can lead to future progress tohelp control and cure these diseases.

It would be rewarding to see other groups use our work to inform their experiments on more complex organisms and eventually influence therapies for neurodegenerative diseases in humans, Wisniewski said.

Neurodegenerative diseases affect millions of people worldwide, with Alzheimers disease and Parkinsons disease being the most common.

I think that it is special that the Marquette science community is being innovative in understanding the early stages of neurodegenerative diseases, Hannah Seeman, a sophomore in the College of Communication said. I value the scientists that are making strides to aid those predisposed to Alzheimers disease since it runs in my family.

The authors of this study include Jaya Sharma, a post-doctoral student in Manogarans lab. Additional researchers on the project include Stephen J. Merrill, a professor of mathematics, statistics and computer science; Emily Paulson, a graduate student in mathematics, statistics and computer science; and Joanna O. Obaoye, an undergraduate biology student.

A mechanism shared by healing wounds and growing tumors – The Rockefeller University Newswire

Cancerous cells in a skin tumor become locked in an abnormal state as a result of the activation of a gene-regulating element (green).

Like an image in a broken mirror, a tumor is a distorted likeness of a wound. Scientists have long seen parallels between the two, such as the formation of new blood vessels, which occurs as part of both wound healing and malignancy.

Research at The Rockefeller University offers new insights about what the two processes have in commonand how they differat the molecular level. The findings, described April 20 in Cell, may aid in the development of new therapies for cancer.

Losing identity

At the core of both malignancy and tissue mending are stem cells, which multiply to produce new tissue to fill the breach or enlarge the tumor. To see how stem cells behave in these scenarios, a team led by scientists in Elaine Fuchss lab compared two distinct types found within mouse skin.

One set of stem cells, at the base of the follicle, differentiates to form the hair shaft; while another set produces new skin cells. Under normal conditions, these two cell populations are physically distinct, producing only their respective tissue, nothing else.

But when Yejing Ge, a postdoc in the Fuchs lab, looked closely at gene activity in skin tumors, she found a remarkable convergence: The follicle stem cells expressed genes normally reserved for skin stem cells, and vice versa. Around wounds, the researchers documented the same blurring between the sets of stem cells.

Master switches

Two of the identity-related genes stood out. They code for so-called master regulators, molecules that play a dominant role in determining what type of tissue a stem cell will ultimately producein this case, hair follicle or skin. The researchers suspect that stress signals from the tissue surrounding the damage or malignancy kick off a cycle that feeds off itself by enabling the master regulators to make more of themselves.

Access to DNA is the key. To go to work, master regulators bind to certain regions of DNA and so initiate dramatic changes in gene expression. The researchers found evidence that stress signals open up new regions of DNA, making them more accessible to gene activation. By binding in these newly available spots, master regulators elevate the expression of identity-related genes, including the genes that encode the master regulators themselves.

Locked in

While wounds heal, cancer can grow indefinitely. The researchers discovered that while stress signals eventually wane in healing wounds, they can persist in cancerand with prolonged stress signaling, another region of DNA opens up to kick off a separate round of cancer-specific changes.

Tumors have been described as wounds that never heal, and now we have identified specific regulatory elements that, when activated, keep tumor cells locked into a blurred identity, Ge says.

The scientists hope this discovery could lead to precise treatments for cancer that cause less collateral damage than conventional chemotherapy. We are currently testing the specificity of these cancer regulatory elements in human cells for their possible use in therapies aimed at killing the tumor cells and leaving the healthy tissue cells unharmed, Fuchs says.

Elaine Fuchs is the Rebecca C. Lancefield Professor, head of the Robin Chemers Neustein Laboratory of Mammalian Cell Biology and Development, and a Howard Hughes Medical Institute investigator.

Anatomy Of A Fake News Story: How A Muslim Politician Became A … – BuzzFeed News

Did you hear the one about how Anne Aly, Australias first female Muslim federal MP, refused to lay a wreath at a recent Anzac Day service?

If youre a traveller in right wing Australian Facebook circles, theres a fair chance you did. From the Kim Vuga Love Australia Or Leave Party page to the Bolt Report Supporters group, rumours of Alys disrespect have been circling for a few days.

The only problem is, its just not true.

The rumour appears to have kicked off at around 8:30pm on Anzac Day which marks the anniversary of Australia and New Zealands first major battle in WWI when it was posted to the Kim Vuga Love Australia or Leave Party page.

The must read story was posted by Vuga, the founder and president of the Love Australia or Leave Party and posed the question: What the hell are they doing in our country? You can guess who they refers to.

The story came to Vuga from Gary, a regular commenter on the page who apparently sent it to her via direct message. It claimed that Gary was at the Wanneroo RSL dawn service, north of Perth in Western Australia.

Everything went very well until the Wreath laying ceremony when the guy announcing the people laying Wreaths said the Local Member Anne Ally would not be presenting the Wreath for the local government, the post said.

What a bitch.

A few hours later Vugas post was picked up by the Fair Suck Of The Sav, Mate Facebook page, where Alys failure to lay a wreath had now become a refusal.

That post was shared more than 450 times by the pages 49,000 followers, and from there it took off, bouncing around the right wing Facebook echo chamber, whipping conservatives into a fevered frenzy about the Muslim MP who disrespected our Diggers.

Alys WA electorate of Cowan has two dawn services one at Wanneroo and one at Ballajura and because the sun only rises once a day, she can only attend one.

Last year it was Wanneroo, so this year she attended the Ballajura ceremony and sent a wreath to Wanneroo, where state MP Sabine Winton laid it on her behalf.

Alys been to three Anzac ceremonies this week, and shell attend three more before the week is out.

Aly, who was a counter terror and deradicalisation expert before entering parliament, says the claims are offensive and distracting.

I have a strong relationship with the RSL, she told BuzzFeed News. I take a lot of pride in it. I work a lot with victims of terror and with first responders, with people who have sacrificed. I have a lot of respect for our service men and women.

The news has now seeped into the mainstream. Aly says shes heard it being reported on some local talkback stations.

Its absolutely disgusting that the very people who are falsely claiming outrage are the same people who are disrespecting Anzac day for their own agenda, she said.

I dont look at my life through the lens of my religious identity. I dont look at everything only through the lens of Islam. But people look at me only through that lens and cant see me as anything else.

When contacted by BuzzFeed News Kim Vuga was unrepentant about any role she played in the spreading of a false rumour.

She said she had never claimed that Aly had refused to lay a wreath, only that she had failed to lay one, and said she trusted her friend Gary to tell the truth.

I only shared what I was given, she told BuzzFeed News.

When asked why she hadnt checked her facts before posting, she said that that was the job of journalists, and perhaps BuzzFeed News would be better off investigating the recent controversy surrounding Muslim writer and TV host Yassmin Abdel-Magied.

Vuga hasnt yet passed on Garys details to us, but if she does, well update this post.
