The amoeba Entamoeba histolytica, in green, takes a bite out of a human cell, outlined in pink. (via sciencemag.org)
This scares me out of my wits
Excuse my French, but this little shit, E. histolytica, —responsible for a diarrhoeal disease that causes thousands of deaths each year in the developing world— kills intestinal cells through trogocytosis, namely, gnawing them. 
Researchers, at the University of Virginia in Charlottesville, discovered that the amoeba bites the living cells to the death (which happens for excess damage) and then… the amoeba spits them out. 
Fierce protists are, indeed, dreadful creatures.

The diameter of the observable universe is about 28 billion parsecs (93 billion light-years), putting the edge of the observable universe at about 46–47 billion light-years away

[2] Panoramic view of the entire near-infrared sky reveals the distribution of galaxies beyond the Milky Way. The image is derived from the 2MASS Extended Source Catalog of more than 1.5 million galaxies, and the Point Source Catalog of nearly 0.5 billion Milky Way stars. The galaxies are color coded by redshift.

[3] The Virgo Supercluster or Local Supercluster is an irregular supercluster that contains the Virgo Cluster in addition to the Local Group. At least 100 galaxy groups and clusters are located within its diameter of 33 megaparsecs (110 million light-years). There are, in the observable universe, millions of superclusters.

والإيمان هو الذي يحرك الإنسان ويوجهه ويولّد فيه طاقات هائلة، لم تكن لتظهر بدونه، بل هو ينشئه خلقًا جديدًا ويولّد فيه طاقات هائلة، لم تكن لتظهر بدونه، بل هو ينشئه خلقًا جديدًا، بروح جديدة، وعقل جديد، وعزم جديد، وفلسفة جديدة. كما رأينا ذلك في سحرة فرعون حين آمنوا برب موسى وهارون، وتحدّوا جبروت فرعون، وقالوا له في شموخ واستعلاء: “فَاقْضِ مَا أَنْتَ قَاضٍ إِنَّمَا تَقْضِي هَذِهِ الْحَيَاةَ الدُّنْيَا”. ـ

al-Iman (faith) is that which puts man into motion; it directs him and creates in him tremendous powers that wouldn’t manifest without it. It rebuilds him into a new creation, with a new spirit, a new mind, a new resolve, and a new philosophy in life. We saw this in the story of the magicians of the Pharaoh when they believed in the Lord of Moses and Aaron, challenged the tyranny of the Pharaoh, and with all the confidence in the world they said to him: “Then decide (regarding us) whatever you want to decide, your decision can only affect this worldly life.” (Quran 20:72)

Spiral Galaxies in Collision

Billions of years from now, only one of these two galaxies will remain. Until then, spiral galaxies NGC 2207 and IC 2163 will slowly pull each other apart, creating tides of matter, sheets of shocked gas, lanes of dark dust, bursts of star formation, and streams of cast-away stars. Astronomers predict that NGC 2207, the larger galaxy on the top, will eventually incorporate IC 2163, the smaller galaxy on the bottom. In the most recent encounter that about peaked 40 million years ago, the smaller galaxy is swinging around counter-clockwise, and is now slightly behind the larger galaxy. The space between stars is so vast that when galaxies collide, the stars in them usually do not collide.

On the 4th of April last year, Lewa lost one of its greatest icons, co-founder Anna Merz. Anna’s courage and tenacity led her to venture into rhino conservation when few would, pioneering the Ngare Sergoi Rhino Sanctuary along with the Craig family in the early 1980s. The Ngare Sergoi was later reinvented as the Lewa Wildlife Conservancy. 

The success of Lewa is a true testament that Anna’s vision and dedication created a greater impact than she had ever hoped for. 

Lewa’s mama vifaru – Swahili for mother of rhinos as she is fondly remembered – leaves behind a lasting legacy of a conservationist whose love and passion for wildlife has inspired people around the world. She is a champion who found her cause and did all she could to protect the animals she so dearly loved. 

Lewa’s history will forever be intertwined with Anna’s; so will the future of black rhinos in Kenya that she dedicated her life to protect.
