PHILADELPHIA — Temple University researchers used a gene-editing technique to remove HIV DNA from the type of human immune cells where the virus maintains a smoldering reservoir of infection. The experiment, building on the researchers’ previous HIV gene-editing work, was conducted in T cells growing in lab dishes. Whether it works in actual patients remains to… Continue reading “Researchers snip HIV from infected cells, suggesting a cure is possible”

Inside the mind of a serial killer
Television shows like “Dexter” and “The Following” have given us a terrifying glimpse into the criminal mind of serial killers. We often catch ourselves asking, “Why do they kill?” “How do they pick their victims?” and “Why can’t they control their impulse to kill?” To answer these questions, Best Counseling Degrees has developed “The Brain of… Continue reading “Inside the mind of a serial killer”
How to save the troops from PTSD
A new Rand study shows that the U.S. military is struggling to meet the needs of war veterans with post-traumatic stress disorder (PTSD) and depression.
According to the study of 40,000 cases, only a fraction of the active-duty troops with the conditions are receiving the minimum number of therapy sessions after diagnosis.
One major obstacle, according to a USAToday interview: “We just don’t have enough mental health professionals to meet the demand,” said Brad Carson, a DoD official.

Yes, Ted Cruz has a ‘resting creep face,’ says science
Ted Cruz Has Resting Creep Face, And It WILL Cost Him Votes There are plenty of reasons (and I do mean plenty) to avoid voting for Texas Sen. Ted Cruz. However, there’s one reason you could be opposed to Cruz that he has no control over, and you might not be consciously aware of. Did you… Continue reading “Yes, Ted Cruz has a ‘resting creep face,’ says science”
Wow
Johnson & Johnson, continuing its long quest for a Type 1 diabetes cure, is joining forces with biotech company ViaCyte to speed development of the first stem cell treatment that could fix the life-threatening hormonal disorder.
They’ve already begun testing it in a small number of diabetic patients. If it works as well in patients as it has in animals, it would amount to a cure, ending the need for frequent insulin injections and blood sugar testing.
ViaCyte and Johnson & Johnson’s Janssen BetaLogics group said Thursday they’ve agreed to combine their knowledge and hundreds of patents on their research under ViaCyte, a longtime J&J partner focused on regenerative medicine.
The therapy involves inducing embryonic stem cells in a lab dish to turn into insulin-producing cells, then putting them inside a small capsule that is implanted under the skin. The capsule protects the cells from the immune system, which otherwise would attack them as invaders – a roadblock that has stymied other research projects.
This isn’t the last time
Scientists have been predicting it all along: As the climate changes dramatically, we’re going to see diseases where we’ve never seen them before, where people have no antibodies. I for one would like to grab those “pro life” climate deniers by the shoulders and shake some sense into them: “See what you’ve done?”
Before last fall, medical reports of babies born with brain damage and unusually small heads — a condition known as microcephaly — were so uncommon in Brazil that only about 150 cases were registered each year in the entire country. Now Brazilian officials are investigating thousands of them, and they contend that the mosquito-borne Zika virus is the cause.
Virus specialists are racing to understand the connection, if any, between Zika and the rash of microcephaly cases in Brazil, an undertaking that international officials warn could take six months or more.
But whatever the cause, “There is no doubt that Brazil is experiencing a significant increase in microcephaly,” said an official for Brazil’s Health Ministry who was not authorized to speak publicly. “We wouldn’t have declared this situation a health emergency if this increase had not been detected.”
The Zika epidemic has spread much faster than science’s understanding of it. Researchers here believe that the virus made the leap from Polynesia to Brazil during the 2014 World Cup soccer tournament. Since then, as many as 1.5 million people in Brazil are believed to have been infected, and the virus has spread to more than 20 countries and territories in the Americas.
Right now, the epidemic is happening in a country where women don’t have access to either birth control or abortion. Nor do they live in a society that can support the special care needed for these families. I don’t think any country is set up to deal with this. It is a nightmare.
The collision sport on trial
The New York Review of Books has an interesting piece by David Maraniss:
I grew up in Wisconsin during the 1960s, when Lombardi’s Packers were winning five championships in nine seasons, and later wrote a biography of him, which might explain why, although baseball is my preferred game, the Packers are my favorite team in any sport. The seasonal progression from radiant fall Sundays to frostbite playoff games in the darkening winter and the superstitions that come with watching the Packers are part of my emotional life, bringing joy and anguish, and if that is pathetic, it is a condition I share with millions of National Football League fans. But my attachment to football has been loosened by an increasing sense of guilt about whether I am complicit in supporting an unacceptably debilitating and duplicitous enterprise. America’s superpower game has never been more popular, yet evidence against it is amassing on many fronts, none more troubling than what science now says about the long-term ramifications of those collisions. I’ve wondered whether I could resolve the conflict between my attraction to the game and concern about what it does. On a larger scale, I’ve wondered whether football could repair itself and be made safer.
In a search for answers, I studied a diverse collection of books, articles, transcripts, and films about football. They included three books that considered the physical, sociological, and financial aspects of the sport to support their theses—Steve Almond’s manifesto Against Football, Gregg Easterbrook’s response, The Game’s Not Over: In Defense of Football, and Gilbert Gaul’s Billion-Dollar Ball, a deeply reported look into the corporatization of the college game and how it can take precedence over academic concerns.
The rest dealt mostly with the neurological effects that football collisions can have on the brain. Two were films: the well-publicized Concussion, a Hollywood movie starring Will Smith as the Pittsburgh pathologist who discovered a neurodegenerative disease in the brain tissue of deceased football players that came to be known as CTE(chronic traumatic encephalopathy), and the not-yet-released documentary Requiem for a Running Back, about Rebecca Carpenter’s quest to understand her troubled father, Lew Carpenter, who played in the NFL with Lombardi’s Packers fifty-five years ago and suffered from CTE. I also read transcripts of television interviews on the topic of football brain trauma conducted by Charlie Rose and PBS’s Frontline; and the essential writings of Steve Fainaru and his brother, Mark Fainaru-Wada, especially League of Denial, a book that documented two decades of obfuscation and deceit by the NFL in dealing with brain injuries.
You already know how I feel. I’ll be surprised if NFL football exists in another 15 years, and good riddance.
One of those things no one likes to talk about
While there are clearly medical benefits to pot, marijuana-induced psychosis is not one of them.
Researchers have been studying the relationship between cannabis and psychosis for decades. Several studies over the last several years have concluded that users who are predisposed to mental disorders are more likely to develop psychosis symptoms. They have also found that psychosis develops earlier in marijuana users.
“I think it’s kind of inherent,” said Dr. Scott Krakower, a psychiatrist at Zucker Hillside Hospital in New York, of the link between cannabis and the onset of psychosis. Krakower has never met Fuentes. “The more you smoke, the more that psychosis is going to continue.”
‘We can now confidently tell our patients with psychosis that giving up cannabis will probably reduce positive symptoms and will help prevent relapse.’
The latest study on the subject — a meta-analysis of 24 studies consisting of more than 16,000 patients — found a strong association between continued cannabis use and relapses experienced by people who have been diagnosed with psychosis or similar symptoms. There was also a strong link between cannabis use and longer hospital stays in patients who used cannabis compared to those who either didn’t or had stopped using it.
This stuck in my mind for all these years after I read “Eden Express,” by Mark Vonnegut (Kurt’s son). Mark was undiagnosed with bipolar disorder and suffered a psychotic break brought on by smoking pot — which no one believed. He’s a doctor now.
This explains so much
Nearly everyone is well aware of the detrimental effects high doses of cocaine can have on the central nervous system. However, most people would never think the way the damage occurs is like something out of a Hollywood horror film. New research on mice finds clues that cocaine actually causes brain cells to cannibalize themselves. This… Continue reading “This explains so much”
Being plugged in 24/7 causes stress and anxiety
While technology makes it easy for us to check our emails outside of work, constantly being plugged in eventually takes its toll on our personal life, raising anxiety and stress levels, according to a recent study. ‘You’ve Got Mail’, carried out by a group of psychologists at the London-based research lab Future Work Centre, focuses on… Continue reading “Being plugged in 24/7 causes stress and anxiety”
