10:00 AM | Somatic mutation: easily dismissible, or mistakenly overlooked?
The numbers of cell divisions that occur in a human embryo is huge, and the number of cells even in a new baby is huge.  An adult is estimated to have many billions if not closer to a trillion cells.  In the mid-80s I estimated that there have been only about 160 billion individuals in the entire history of our species (i.e., Homo sapiens, not our ancestors). Each cell division produces two daughter cells, and these then divide and so on, generating an expanding tree of cellular […]

8:00 AM | The Mysterious Disappearance Of JFK’s Brain
In 1963, John F. Kennedy was assassinated, and his brain was locked away in the National Archives. However, three years later, government officials discovered the president's brain had disappeared without a trace. Needless to say, the disappearance of JFK's organ has given rise to some pretty crazy conspiracy theories. The post The Mysterious Disappearance Of JFK’s Brain appeared first on KnowledgeNuts.

5:48 PM | Introducing the new garden
Well, we’ve been here a couple of weeks now, so it’s time I introduced you to the garden :) It’s a real blank canvas at the moment, waiting for me to have the time to start working on it. The front garden is the sunniest spot, and can be considered to be in full sun: My front garden The front garden is 6.8 m along the house and 3.1 m wide. That trellis panel is prime plant real estate – possibly the best spot in the garden for something that likes it sunny. I […]

11:57 AM | Micrograph of the Month: Bits of Bones
For the past few weeks I have been revisiting some old slides from the TP excavation area at Catalhoyuk. I collected these samples  in 2004, and they were some of the first that I worked on for my PhD. At the time I found them a bit disappointing, as there is a lot of bioturbation and erosion  going on in this part of the site, which means that trying to reconstruct activities using microstratigraphic analysis is difficult. The TP area is located very close to the surface of […]

11:33 AM | The identification of Vitamin D Deficiency in Adults from Post-Medieval Sites.

During my pathology course at Uni we touched on this and therefore thought it would be a good article to focus […]

9:35 AM | Why The Center Of The Universe Is In Idaho
Wallace, Idaho is one of a handful of town in Idaho's Silver Valley region, famous for not only its silver mining but also for other chemicals and compounds that no one has been able to satisfactorily prove to the EPA are harmless. Since the EPA has said that if things can't be satisfactorily disproved then they must be, in fact, proved, Wallace has declared itself the Center of the Universe. It's never been disproved that it's not the center, so therefore ... it is. The post Why The Center […]

8:00 AM | TMI? Personalized probability
I went to my dentist on Friday expecting to go home with a permanent crown on one of my molars but I went home with an appointment with an endodontist for evaluation for a root canal instead.  My dentist, who I think is a very good one, said that 6% of people getting crowns go on to need a root canal, and, based on my symptoms, he was 90% sure I'd be one of those 6%.  Lovely.But what does that 6% even mean?  Just off the top of my head, it could reflect the fallibility of […]

7:00 AM | Jewish People Were Forced To Become Moneylenders
The conspiracies about Jewish bankers go back a long way and are so ingrained that even many people who are not anti-Semitic buy into the theory. Historically, there have been many Jewish people involved in banking, but it was never a conspiracy. In actuality, due to usury laws prescribed by the Jewish scriptures, the Jewish people were considered the logical choice to handle the moneylending. To make matters worse, many Jewish people were barred from other occupations, so they had to take what […]

Disappearing ‘Chinese lanterns’, the ornamental Physalis alkekengi It has been a long, warm autumn in my area, and we have yet to experience the first frost of winter – but the leaves are falling and it’s clear that colder weather is on the way. Very little sown or planted now will put on much growth, as the days are short and there isn’t enough light. But bulbs, perennials and hardy veg will be putting down roots, ready to emerge as the days begin to get longer […]

7:00 AM | The Exciting Future Of Hoverboard Technology
If you've watched the Back to the Future trilogy, then you probably remember the iconic hoverboard that Marty McFly rides. For the longest time, people thought this technology was impossible, but we may soon have truly functioning hoverboards on the market. The board currently in development uses magnetic fields to make the board hover about an inch above the ground with a fully grown human standing on it, although it can only work over non-ferrous metallic surfaces because of the […]

7:09 PM | Who needs an osteologist? (Installment 20)
This story seems to have slipped my notice over the last two weeks, but a team of radiologists in West Palm Beach, Florida, scanned an Egyptian mummy dating to 30-300 AD in advance of its going on display at the South Florida Science Center and Aquarium.According to the news reports, which aren't terribly great, 40 years ago the mummy was studied, and researchers thought the mummy was that of a girl between the ages of 4-9 who died of tuberculosis.  The diagnosis rested on missing […]

7:00 AM | The Difference Between Occultism And Mysticism
Both practices involve the alleged ability of the human mind to reach out and experience that which is beyond our regularly experienced senses. Mysticism often exists within the context of organized, established religion, while the same religion condemns occultism. Occultism is an experience of conflict whereby the person practicing it is attempting to control something or learn something that they shouldn't know, while those who practice mysticism are striving to exist in harmony and peace […]
