THOUSANDS YEARS OF CRY ON CRY DECODED
The service allows scientists to go onto the “Exchange” and find other scientists or researchers that specialize in the area of work that they need completed. They then pay this individual or individuals to complete that portion of the project while they continue on with other areas of the work that are more in line with their own specialties. Likewise, they can increase their own funding for projects by taking on a component of another lab’s work. As reported in Singularity Hub, it’s about opening up access to experts and specialized equipment in various fields. In this age of highly specialized technological and scientific information, many scientists lack the expertise to address certain aspects of a scientific experiment or innovation, and so must find some other professional in the field with those skills. Science Exchange makes this easy and mutually beneficial by carefully vetting members of the exchange, and then giving them access to their worldwide network.
The widespread use of fMRI (functional magnetic imaging) has allowed researchers to watch as sensory stimuli literally “light up” various areas of the brain, which has lead to some very illuminating understandings of how our brains actually work. One of those areas, our “moral” center, is actually closely connected to the area of our brain in which physical revulsion is located. In other words, according to our brain circuitry, morality and disgust are closely related.
There have been a few Herculean hurdles in the quest to be able to create spider-silk fibers on a massive scale. Although geneticists have been able to isolate the proteins within a spider’s silks (in fact, they’re so good that they can even genetically customize the silks for different properties), they have not been able to figure out how to turn them into fibers.
Scientists at Scripps Research Institute have recently found that schizophrenia is not a genetic disorder at all. In fact, it’s an epigenetic disorder, one cause by the structures of the cell that house our DNA. Particular to disorders like schizophrenia, there is a protein that functions a bit like a storage rack in the cell called a histone. The DNA, which would not otherwise fit within a single cell, is wrapped around the histone. However, in order for the DNA to express itself the histone has a tail which undergoes a perpetual chemical reaction called acetylation, which relaxes the DNA and allows it to express. Then acetylation takes place and the DNA once again contracts around the histone. The histones and DNA create chromatin, which manages the constant cycle of relaxation and contraction that allows all the genes of a cell to functions properly.
AHPTN 052, showed the antiretroviral drugs (ARVs) not only slow the progression of the disease in patients already infected, but virtually eliminate transmission to uninfected individuals. In fact, the study was so incredibly effective that four years before it was slated to end, a third party monitoring board declared that all subjects, even the control group, were to be immediately vaccinated with the ARVs. Here, in no particular order, are a few of the highlights. John Cohen, who wrote the covers story in Science, had this to say about the findings.
Have you ever had the desire to experiment in a biology lab, replete with all of the necessary tech and equipment? Were you the kind of kid that wanted to try tons of things in the science class labs that were not on the worksheet? Do your hobbies include experimenting with genetic splices? If the answer to any of these is yes (or even ”sure”), you may be excited to learn about DIYBio, a new organization that is designed to attract and support “citizen scientists” as they dabble in the fields of biology and biotechnology. An outgrowth of DIYBio has been BioCurious, a Sunnyvale, CA organization that has mixed the openness and networking from DIYBio into a physical space where people in the Bay Area community can work with equipment, under a code of ethics and a community of experts, and collaborate on others’ ideas and projects in a collaborative atmosphere.
