    Thrombotic Thrombocytopenic Purpura

    Thrombotic Thrombocytopenic Purpura (TTP) is a rare blood disorder characterized by clotting in small blood vessels of the body (thromboses), resulting in a low platelet count. In its full-blown form, the disease consists of the pentad of microangiopathic hemolytic anemia, thrombocytopenic purpura, neurologic abnormalities, fever, and renal disease.”

    Image 1: Peripheral smear from a patient with thrombotic thrombocytopenic purpura: Red blood cells are fragmented and appear as schistocytes. Certain schistocytes have the appearance of helmet cells (H). Spheroidal cells often are present (S). Occasional nucleated erythroid precursors may be present.

    Image 2: A small platelet-fibrin thrombus is seen in a glomerular capillary above the arrow. This occurred in a patient with thrombotic thrombocytopenic purpura (TTP). This rare coagulopathy mainly affects kidneys, heart, and brain with small arteriolar thrombi. Acute renal failure can occur. The classic pentad of fever, acute renal failure, neurologic changes, thrombocytopenia, and microangiopathic hemolytic anemia is often present.

    "Human action is the only element in primitive experience that exhibits any connectedness: the only system of interrelated doings that people have any grasp of is what goes on in their society. Hence, making sense of the world at large must consist in conceiving it in social terms: purposes, motives, will, good, evil, love, hate, and other emotions. Primitive worldviews must be teleological; agency must be personal, volition must be the only causation recognized.”

    Forty-five years ago today, two human beings first set foot on the moon. On July 20, 1969, the lunar module of Apollo 11 touched down in the Sea of Tranquility, and forever changed how we view our place in the universe. When I think about the fact that four and a half decades ago, at the very moment I am writing this, Neil Armstrong and Buzz Aldrin were walking on the freakin’ moon, I am humbled and inspired.

    I’ve combined some of my favorite photos from Apollo 11 with some of the actual words spoken by Neil Armstrong, Buzz Aldrin, and Michael Collins.

    If you’d like to relive the historic mission moment by moment, word by word, and photo by photo, head over to SpaceLog

Evolution of life’s operating system revealed in detail
The evolution of the ribosome, a large molecular structure found in the cells of all species, has been revealed in unprecedented detail in a new study.
Around 4 billion years ago, the first molecules of life came together on the early Earth and formed precursors of modern proteins and RNA. Scientists studying the origin of life have been searching for clues about how these reactions happened. Some of those clues have been found in the ribosome.

Comet Pan-STARRS Marches Across the Sky
NASA’s NEOWISE mission captured a series of pictures of comet C/2012 K1 — also known as comet Pan-STARRS — as it swept across our skies in May 2014.

Cosmic inflation: BICEP2 and Planck to share data
Scientists on rival projects looking for evidence that the early Universe underwent a super-expansion are in discussion about working together.
The negotiations between the US-led BICEP2 group and Europe’s Planck Collaboration are at an early stage.
BICEP2 announced in March that its South Pole telescope had found good evidence for “cosmic inflation”.

Plasmepsin V, a Secret Weapon Against Malaria 

Plasmodium falciparum and Plasmodium vivax are single-celled parasites that, between them, are responsible for the vast majority of malaria cases in humans. Of the two, P. falciparum often provokes the most acute symptoms, whereas P. vivax is associated with a recurring, chronic version of malarial disease. Both parasites spend a large portion of their life cycle living and replicating within human red blood cells (erythrocytes).
While inside erythrocytes, the parasites express and secrete more than 450 proteins. Each of these proteins has a different function for the parasite, but many of them share a distinctive feature: an amino-terminal motif called the Plasmodium EXport ELement (PEXEL). This special sequence of amino acids directs proteins into the export pathway, but it is partially removed while the protein is still within the parasite’s endoplasmic reticulum by an enzyme called Plasmepsin V (PMV). On the basis of this prominent function, it seems likely that PMV is important for parasite survival and may therefore be a good target for antimalarial drugs.
