Cancer, could it be just bad luck?
|
view preview
In a paper this week in Science, two scientists at John Hopkins have united biology and mathematics to propose a mathematical formula to explain the genesis of cancer. Take the number of cells in an organ, identify what percentage of them are long-lived stem cells, and determine how many times the stem cells divide. With every division, there’s a risk of a cancer-causing mutation in a daughter cell. Thus, Tomasetti and Vogelstein reasoned, the tissues that host the greatest number of stem cell divisions are those most vulnerable to cancer. When Tomasetti crunched the numbers and compared them with actual cancer statistics, he concluded that this theory explained two-thirds of all cancers. “Using the mathematics of evolution, you can really ...

The best way to pass away
|
view preview
I have not given 'the best way to die' much thought yet, but apparently a leading doctor and the former editor of the prestigious British Medical Journal (BMJ) has claimed cancer is the best way to die. Dr. Richard Smith believes that cancer provides opportunity to reflect on life before it ends is important and urges charities and the medical world to "stop wasting billions trying to cure cancer". In a blog published in The BMJ, the doctor wrote that while most people tell him they would prefer a sudden death, he thinks that is very hard on the families of the deceased. "The long, slow death from dementia may be the most awful as you are slowly erased, but then again when death comes it may be just a light kiss," he wrote. "Death from organ f ...

Two different thinking systems of the human mind
|
view preview
There are two different "thinking" systems that predominate our brain. They are responsible for our first impressions and then later changing them, our in depth views and perspectives, in addition modulating our thinking with respect to a given context. System one is mainly the "fast" thinking system. System two is a relatively slower thinking system. Their remarkably different yet crucial functions are portrayed beautifully in this video.

Rosetta's Comet - Update
|
view preview
Remember Philae? That little lander that was targeting comet Rosetta? https://biology-forums.com/index.php?article=1050It was very big news around two months ago... Sadly, Philae landed incorrectly in a rather awkward position due to technical failings. After all, it was trying to land on the harsh, unstable, deteriorating/burning up surface of a comet. It bounced three times to a site away from the targeted position and ended up in a shady place with insufficient sunlight to recharge its energy reserves. And so it died out after 60 hours of touchdown. Recent tabloids have now reported that Philae is missing! Scientists from the European Space Agency have tried to analyze the images that Philae returned but things just keep on getting more ...

Queen Khentakawess and Osiris
|
view preview
I am not sure if such blogs are welcome here, but I will try sparking enthusiasm in this subject. Alongside my major field of interest, I have an unhealthy/obsessive curiosity distortion in the archaeology field, specifically Egyptology. And recently, two major discoveries have been made in the Ancient Egyptian land. The first discovery made was that belonging to an Ancient Queen named Khentakawess's the 3rd's tomb, which was located near her husband's tomb, Pharoah Neferefre. These two, date back to the 4th or 5th dynasties, that is approximately 4000 years back in history. Around that time, the first three pyramids, yes, the ones that we see all the time and are the most famous pyramids of Giza, were being built by Pharoahs Khufu, his son ...

Have you ever chillaxed (chilling and relaxing  ) under the sun, cloud watching, and all of a sudden noticed transparent blobs floating around? Did you know what these things were? I know I didn't until I saw this:

Walking sushi

view preview
While this may look like sushi, it's actually Argentina's pink fairy armadillo. This rarely seen animal has silky white hair and a pinkish carapace; it ranges in size from 3.3 to 4.6 inches (84 to 117 millimeters) long, making it one of the smallest species of armadillos. The animal is also nocturnal and has the ability to bury itself in lightning speed given its long claws, which are an astonishing one-sixth the length of the body. ...
