Fish in a Pond

by Vatche Sahakian in Schrödinger's Dog

Things are so because things couldn't have been any different… In recent years, cosmological observations have painted a remarkably detailed picture of the history of our universe. The bad or good news (depending on your perspective) is that some of the conclusions are astounding: results suggest an extremely delicate balance all around us, so delicate that if things were to be a tiny bit different at the beginning of time, perhaps we would not be around to ask any questions… ........

Novel Approach for anti AIDS drug development.

by B V Waghmare in HIV virus and antiretroviral drugs and antiAIDS vaccine research and developmets

HIV virus when it incorporates its DNA in human T-Lymphocytes , it integrates in a very controlled manner so that it takes care that our T-Lymphocytes cells do not get destroyed before they code and generate HIV virus proteins and genetic material and form enough new HIV viruses.
Professors Abraham Loyter, Assaf Friedler and their colleagues have reported that they have developed a peptide called as “MIX”

Peptide “MIX” is able to increase activity of HIV virus enzyme ........ Read more »

Diversity: It Matters! (for plants & algae)

by jebyrnes in I'm a chordata, urochordata!

Geological time has witnessed 5 extinction crises. Now we're in the middle of the 6th - this time driven by man. What's unprecedented, however, is the rate we are driving species extinct. For many taxa, it's faster than we've seen in geological time (see here for discussion).

So? Will vast reductions in the diversity of species on earth matter? I mean, heck, maybe we only need two or three of each taxa, and we’re all good. Or maybe not…

This question has ........ Read more »

Why speeding neutrinos are interesting for social scientists

by Rense Nieuwenhuis in Curving Normality

In the world as we understand it, based on Einstein, nothing can go faster than light. This prediction based on the general theory of relativity has proven itself countless times in empirical research. And now, lo and behold, a group at CERN has observed neutrino’s racing through earth from France/Switzerland to Italy at the World-record breaking speed of slightly above light-speed!... Read more »

Bioplastics in Bloom

by Whitney Campbell in Green Screen

When imagining the world without a dependence on petroleum, I tend to think of objects like solar panels, electric cars, and wind turbines — the things that could potentially replace the parts of the current oil-energy infrastructure. But what about the other items made from petroleum that could be replaced by alternative materials? What about bicycle tires, nail polishes, compact discs, surf boards, lipsticks, tool boxes, and shower curtains?... Read more »

Wikipedians: are they really grumpy and close-minded?

Three Top Redox-Reagents for preventing protein oxidation

by Vicky Doronina in Protein Solubility Blog

Intact cells contain enzymatic and non-enzymatic systems, which counteract amino acid oxidation by reactive oxygen species from the air and chemical reactions and return them into unmodified state. However, after you break the cells, the anti-oxidation systems are gone and you have to supply excess of external antioxidants. In general, the concentration of the reducing agent should be more than your protein concentration. The good old dithiothreitol (DTT) or β-mercaptoethanol (BME) are no........ Read more »

Understanding PREDIMED and the Mediterranean diet: heart-healthy or hype?

by Kismet in Biogerontology and Health

I am going to discuss the failings of the PREDIMED study, real and imagined. I will do this in a Question & Answer style. Several questions are inspired by and NEJM comments and even statements by the low fat "gurus", Essselstyn, Ornish, McDougall or Pritikin. It is no surprise they are up in arms after the study has been published. It threatens their livelihood.... Read more »

Spontaneous Alternation for T Maze, Y Maze

by Adam Maze Engineers in Maze Engineers

Spontaneous alternation behavior (SAB) is a fancy, sciency way of describing the natural tendency of animals (specifically mice/rats/rodents) to alternate which arms of a maze they choose to check out. Unlike the tests for reference and working memory that we discussed last week, when studying spatial memory through observation of spontaneous alternation behavior, the arms of the mazes do not contain any reward. Mice are simply put into the maze, allowed to explore, and their sequence of choices........ Read more »
