A young man lies unconscious on the table, his head clamped firmly in place. His eyes are closed. The hair over his left temple has been shaved.

TONY STARK DOES SCIENCE
Scientists have for the first time synthesized a chromosome of a eukaryotic cell (in this case, a yeast).
A genetic sequence was designed on a computer, then pieced together and integrated into a living yeast cell to create a semi-artificial life-form.

Pusheen the cat making some chemistry.
That cat is not wearing safety goggles, he hasn’t even bothered to clean up that spilled solvent, and he is holding that Erlenmeyer flask way to close to his face.

Some might know Nichelle Nichols best from Star Trek, but this actress, singer, dancer and space advocate has much to say beyond her role in TV’s exploration of the final frontier. In this exclusive interview, she talks about how science fiction and Star Trek—and specifically her ground-breaking role as Chief Communications Officer Lt. Uhura—not only impacted her life, but also had an influence on society over space and time.
This is a really wonderful interview. She sings “Beyond Antares” (she still has a totally amazing voice btw) and discusses how she got onto Star Trek and her decision to stay on the show.
A dozen brain regions, working together, create feelings of passionate love. Stephanie Ortigue of Syracuse University and her colleagues worldwide compared MRI studies of people who indicated they were either in love or were experiencing maternal or unconditional love. The comparison revealed a “passion network”—the red regions shown here at various angles. The network releases neurotransmitters and other chemicals in the brain and blood that create the sensations of attraction, arousal, pleasure…and obsession.

Impulsive–compulsive disorders such as pathological gambling, hypersexuality, compulsive eating, and shopping are side effects of the dopaminergic therapy for Parkinson’s disease. With a lower prevalence, these disorders also appear in the general population. Research in the last few years has discovered that these pathological behaviors share features similar to those of substance use disorders (SUD), which has led to the term “behavioral addictions”. As in SUDs, the behaviors are marked by a compulsive drive toward and impaired control over the behavior. Furthermore, animal and medication studies, research in the Parkinson’s disease population, and neuroimaging findings indicate a common neurobiology of addictive behaviors.
If you have to take medication for a degenerative disorder of the central nervous system, and as a result experience decreased impulse control, what determines the amount of blameworthiness when you steal, cheat or kill?
According to a recent study done by doctors at Cincinnati Children’s Hospital Medical Center, high school athletes who play collision sports at higher altitudes are less likely to suffer from concussions than those who play at lower altitudes.
The doctors who were involved in the study recognized that prior research indicated that the volume and/or pressure of intracranial fluid, which acts as a cushion to protect the brain inside of the skull, is affected by one’s altitude and that it may be associated with the likelihood and/or severity of a concussion.
When concussion rates were examined relative to altitude, sequential elevations in altitude above sea level were associated with a reduction in concussion rates overall. Specifically, high school sports played at higher altitudes demonstrated a 31 percent reduction in the incidence of total reported concussions.
Interesting. I feel like this is more of a mediating factor than a contributing factor….
I have to ask about the comparative weights and training of these higher altitude students? Also, is there maybe a cultural difference? could football be less important to these groups, and therefore they don’t play/hit as hard? are there any outliers? is reporting as common in those areas? very interesting though…high biological probability.
Tomorrow (Saturday) is the birthday of Dmitri Ivanovich Mendeleev - the man whose ground-breaking work led to the creation of the modern periodic table of elements.
Here’s a fun look at his contributions from Lou Serico and TED-Ed:
This unbiased video on fracking gives you all the information you need to know about the oil extraction process.
unbiased is a bit handed of a word to use. but I think it brings up very important issues and gives a general idea of what’s going on. all in all we have to come up with new renewable forms of energy.
I sent this paper to JK Rowling explaining how the wizarding gene could be singular, autosomal, and dominant despite the protests of a bunch of fans who stopped learning genetics after Punnett squares. Warning: Contains science
COOOOOOOOOOOOOOOOOOOLEEE it’s me and you!!!
Seriously, whenever I use a flip phone the first thing I always think of is Star Trek :D
THIS SHIT AIN’T RIGHT
STAR TREK DIDN’T PREDICT THE FUTURE FOOL
IT CREATED THE FUTURE
IT INSPIRED THE FUTURE
THE REASON THESE THINGS EXIST IS BECAUSE STAR TREK MADE PEOPLE WANT THEM TO HAPPEN
STAR TREK IS THE FUTURE
