Scipsy: Implicit Self-Stigma in People With Mental Illness:

Stigma is a burden on many people with mental illness. […]

Stigmatized individuals face public discrimination, and are targets of negative stereotypes; moreover, they often agree with these stereotypes and apply them to themselves, resulting in low self-esteem.

This process is referred to as…

scipsy:

Representative autofluorescence images of olive (cv. Picual), Mediterranean cypress, lily and turnip pollen before (Fig. 1A, B, C and D, respectively) and after (Fig. 1E, F, G and H, respectively) rehydration. Images were obtained with a confocal laser microscope and represent the sum of the fluorescence emitted at 5901650 nm and 650LP nm after excitation at 543 nm (green laser) and 633 nm (red laser), respectively. Different pseudocolours were used to differentiate species. T, trichome. Bars= 100 µm.

Through The Wormhole - S02E06 Are There Parallel Universes?

Imagine you will die tomorrow morning in a horrific car crash. Somewhere far, far away, there’s an exact version of you that got in the same car, drove the same route, and collided with the same commuter. But this other version of you survives to drive another day. It may sound like science fiction, but it’s looking more and more scientifically likely. Somewhere out there, beyond the cosmic horizon, inside a black hole, or as close as an atom’s length away, there could be a parallel universe. If this is the case, how could we ever know? And would we ever be able to pay this universe a visit?

Newly developed fluorescent protein makes internal organs visible

Newly developed fluorescent protein makes internal organs visible:

sciencenote:

For the past 20 years, scientists have used a variety of colored fluorescent proteins, derived from jellyfish and corals, to visualize cells and their organelles and molecules. But using fluorescent probes to peer inside live mammals has posed a major challenge. The reason: hemoglobin in an animal”s blood effectively absorbs the blue, green, red and other wavelengths used to stimulate standard fluorescent proteins along with any wavelengths emitted by the proteins when they do light up. To overcome that roadblock, the laboratory of Vladislav Verkhusha, Ph.D., associate professor of anatomy and structural biology at Einstein and the study”s senior author, engineered a fluorescent protein from a bacterial phytochrome (the pigment that a species of bacteria uses to detect light). This new phytochrome-based fluorescent protein, dubbed iRFP, both absorbs and emits light in the near-infrared portion of the electromagnetic spectrum – the spectral region in which mammalian The researchers targeted their fluorescent protein to the liver – an organ particularly difficult to visualize because of its high blood content. Adenovirus particles containing the gene for iRFP were injected into mice. Once the viruses and their gene cargoes infected liver cells, the infected cells expressed the gene and produced iRFP protein. The mice were then exposed to near-infrared light and it was possible to visualize the resulting emitted fluorescent light using a whole-body imaging device. Fluorescence of the liver in the infected mice was first detected the second day after infection and reached a peak at day five. (See accompanying image.) Additional experiments showed that the iRFP fluorescent protein was nontoxic.

I have a soft spot for anything fluorescent.

Chemistry For The Zombie Apocalypse

Ever wondered how to make a corpse camouflage a la The Walking Dead? It was an effective way for Grimes to hide the living from zombies, literally rubbing themselves in dead guts. Could we synthesize “dead guy” scent? Sure.

Here’s the chemistry lesson, just in case.

A bacteriophage (shown above) is a type of virus that hijacks a bacteria and uses it to reproduce and thus infect its host. It will land on a bacteria and inject its genetic material into it. The bacteria will then allow the virus to reproduce.
