Researches chose the image of a human hand, representing the first form of human painting, to be the first DNA encoded image in a living form!
They inserted DNA sequences that represent the image into the genome of bacteria. Later, They decoded the sequences into an image using a computer algorism with at least 90% accuracy.

Harry Potter fans know very well that witchcraft can be dangerous.
Harry broke his ‘arm’ ( in reality, it was both-bone forearm fracture) during a Quidditch game and was ‘doctored’ by Professor Lockhart. The spell he used, Brackium Emendo, did not work as intended: instead of healing the bones, it made them disappear. Harry was then taken to the Hospital wing and treated with Skele-Gro, an awful tasting potion that grows missing bones.
I offer these few points to consider from an Orthopedic point of view:
This is a Sports injury! Should Quidditch players not wear protective ‘armor’?
Can this spell truly heal broken bones instantly? No cast! No Surgery! No down time! I should go spend sometime at Hogwarts.
Oops. The spell did not work after all. On top, it had the unintended consequence of missing bones: a Complication.
The ‘Doctor’ did not explain the treatment ( the spell itself), its risks ( missing bones), other alternatives ( let it heal with a cast), and did not get consent for treatment. In fact, Potter did not want him to cast the spell! In our world, it is an easy law suit!
The ‘credentials’ of the ‘doctor’ were suspicious to start with. Was he Witchcraft-Certified? even better for the law suit.
Skele-Gro was used to reverse the complication. Where can I get one? Would it work on stubborn fractures ( nonunions) and missing bone fragments? Yet another reason to visit Hogwarts.

Lucy, the famous 3 million years old hominin, has been a mistery for the last few years: how did she die? A group of orthopedic surgeons were asked to review recently obtained 3D CT scans of her skeletal remains and recognized something we are all too familiar with: fracture patterns of the shoulder and other bones that we see with high energy injuries in humans. Those were fractures that happened just before and led to her and not bone breakdown that happens to bone fossils.

In 1996, an amateur archaeologist found a humerus bone north of Berlin. A flint arrowhead was embedded into the one end of the bone, ( funny it is nicknamed the surgical neck) prompting archaeologists to dig more. They found 130 people and five horses so far, and the bones were dated to about 1250 B.C.E., Europe’s Bronze Age. It is estimated that as much as 4000 warriors took part in the fighting- a large number for the bronze age which reflects significant advances in social organization to supports armies of this scale. “It could be the first evidence of a turning point in social organization and warfare in Europe,” one author said.
Recent research at UC Davis Health System looked into two questions about knuckle cracking: What causes the “crack” sound, and does it damage the hand? Ultrasound evaluations showed that the knuckle–cracking sound occurs when gas bubbles form in joints very quickly — faster than the blink of an eye. The study also suggests that the “crack” is caused by bubble forming, rather than bubble bursting.
Examinations by hand specialists found no problems in the joints of knuckle crackers, a finding that contradicts a previous study that suggested that knuckle cracking may cause joint swelling and weaken grip.
Author’s note: I personally used to crack my knuckles. My 8-years-old don does that now. I keep telling him not to do it, but- I guess- I do not have a good reason anymore…
A team of researchers decided wanted to find out what people thought of doctors how that compared to … Santa.
The researchers showed a film in which a narrator dressed as either Santa Claus or a doctor and told an identical story.
1- Santa Claus was perceived to be friendlier.
2- Both were equally reliable….

Tim Anderson, a freelance chef who won the BBC’s MasterChef competition in 2011, donned a special pair of gloves and started cooking. Those were motion sensor gloves, and his moves were being recorded and coded- and the data was fed into the all new Robot Chef!
Anderson taught the robot how to prepare stir fry, sushi, steak, pasta as well as crab bisque. The plan is to teach the robot about 2000 dishes before releasing it to the public.
But don’t give away all your cookbooks just yet. The robot chef costs about $15,000.

Scientists think they may have solved an old question about the cracking of knuckles: Why does it do that?
The crack apparently comes from a bubble forming in the fluid within the joint when the bones separate. It’s like a tiny air bag inflating. This theory about knuckle-cracking was first proposed in 1947 but challenged in the 1970s.
One guy, who is really good at cracking his knuckles volunteered to put his hand inside a special MRI scanner, and made a movie of the inside of his knuckles as they pulled on the end of each finger to make it crack. What they saw was clear: The cracking sound comes when a bubble forms between the bones of the knuckle joint — not when it collapses.
The discovery challenges the common misconception that knuckle-cracking causes arthritis.

Sunday mornings are always pancake mornings. And I do accept special requests. We have had snowman, gingerbreadman, and and bunny rabbit for breakfast before. So, this Sunday morning, as usual, my 3 year-old woke up and was ready for his pankace.
What are we going to have for breakfast? Well, my older son, 6, was fighting zombies yesterday. You figured out the rest…
