New treatment for leukemia with 93% remission rate, Happiness gene is real, Spanking =/= good results, 1-minute workout as good as 45 minutes, Birdbrain no longer an insult.
Exciting results from a new trial conducted by the Fred Hutchinson Cancer Research Center.
27 of 29 patients all of whom had an advanced type of leukemia went into remission after their T cells were genetically engineered to fight their cancers.
The experimental therapy is designed in such a way that it harnesses the power of the immune system to fight cancer. By taking patients T cells and genetically engineering them with a synthetic receptor molecule called a CAR (chimeric antigen receptor) the T cells can recognize and kill cancer cells with a the marker CD19.
While the results are extremely promising, not all of the patients stayed in complete remission and required another round of treatment. These are all important to steps in order to understand and improve treatment strategies.
Dr. David Maloney, senior author said: “In early-phase trials, you’re continually learning. You don’t expect results like these from early-phase trials. That’s why these response rates are so extraordinary”
For the first time ever, researchers from Vrije Universiteit Amsterdam has isolated the part of the human genome that could explain how humans experience happiness.
Professor Meike Bartels said, “This study is both a milestone and a new beginning: A milestone because we are now certain that there is a genetic aspect to happiness and a new beginning because the three variants that we know are involved account for only a small fraction of the differences between human beings.”
The team also found overlap with depressive symptoms and hope that this research can also offer new insight into the causes of depression.
Experts from the University of Texas at Austin and the University of Michigan have published the most complete analysis to date of outcomes associated with spanking. The team looked at 50 years worth of research and more than 160,000 children.
The team concluded that the more children are spanked the more likely they are to defy their parents, experience increased anti-social behavior, aggression, mental health problems and cognitive difficulties.
According to a 2014 UNICEF report, around 80 percent of parents around the world spank their children, despite the overwhelming evidence that spanking does the opposite of what parents want to achieve.
Elizabeth Gershoff, an associate professor of human development and family sciences said: “We as a society think of spanking and physical abuse as distinct behaviors, yet our research shows that spanking is linked with the same negative child outcomes as abuse, just to a slightly lesser degree.”
A new study from McMaster University has basically eliminated the most common excuse for not exercise, the ol’ “I have no time”.
The team recruited 27 sedentary men and split them up into three groups, one group had to perform three 45-minute workouts per week, the other group just three 10 minute sessions per week and finally the control group that did no exercise.
The 10 minutes of exercise consisted of a two minute warm up, three minute cool down, 3 x 20 seconds of all-out cycling, with a total of two minutes recovery in between.
After 12 weeks of training, the results between the 45 and 10-minute groups were remarkably similar, even though the 45-minute group had committed five times as much time exercising.
Martin Gibala, a professor of kinesiology at McMaster and lead author on the study said: “Most people cite ‘lack of time’ as the main reason for not being active Our study shows that an interval-based approach can be more efficient — you can get health and fitness benefits comparable to the traditional approach, in less time.”
Researchers from Lund University have shown that ravens are just as clever as chimpanzees, despite that fact that their brains are much smaller.
The study indicates that the neuronal density and structure of the brain play a more important role than size alone in establishing intelligence.
Can Kabadayi, doctoral student in Cognitive Science said: “There is still so much we need to understand and learn about the relationship between intelligence and brain size, as well as the structure of a bird’s brain, but this study clearly shows that bird brains are not simply birdbrains after all!”
