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.

Washing your hands- straightforward, or is it?
There’s plenty of evidence that washing one’s hands can reduce the spread of disease, only 5% of people wash their hands ‘properly’ ‘all the time’.
10% of 3000 people were witnessed leaving public toilets without washing their hands, and of those who did,33% didn’t use soap. While it is well established that we need to wash our hands properly, there are plenty of myths about what is proper.
Does the water need to be hot to get your hands clean?
In a survey of 500 adults, 69% believed that the temperature of the water has an impact on the effectiveness of hand-washing. Researchers found that water temperature made no statistically significant difference when other factors are controlled. Temperature still affects washing, though, because excessively cold or hot water lets people spend less time washing their hands than comfortable water temperature.
Is anti-bacterial hand wash better than soap?
A 2007 and a 2015 review both concluded that anti-bacterial hand washes did not reduce the number of bacteria remaining on people’s hands after washing any more than soap did, nor was it any better than soap. Triclosan, a main ingredient on most antibacterial hand soaps, May increase anti-bacterial resistance and that and has been banned in the US and in the European Union.
Do you need to dry your hands afterwards?
Letting new hands air-dry is fine as long as he did not contaminated hands before they try out. Durkan’s transfer to your hands more easily if they’re wet.
Hand dryer or hand towel?
There’s a lot of debate surrounding this one. Most of us don’t want for as long as 45 minutes needed for the hands to dry using hand dry. New were hand dryers take 10 seconds hand and our equivalent to paper towels.
Making toilets nicer also makes a difference. One study observe 3,000 people in the US, found that if the toilets were clean and well-kept, people were more likely to stop and wash their hands properly. When the sinks were dirty, they just wanted to get out of there.
Whichever way you choose to wash and dry your hands, do it for longer than you think.

Everyone has experienced that tingling sensation in the hands. It is commonly called “pins and needles” because it feels like tiny pointy needles. Some describe it as numb, or “falls asleep,” and is uncomfortable to place pressure on it.
The sensation itself is called “paresthesia,” or alternate sensation.
Sensation is transmitted from your body to your brain via nerves, your biological Internet cables. If you place too much pressure on one of them, the signal gets distorted. We call it Neuropathy, ie sick nerves. Once the pressure is relieved, it goes back online soon. If the pressure is not removed within reasonable time, it causes permanent change to the inner structure of the nerve and permanent change to the signal. More severe and long standing pressure can cause permanent loss of signal even. There are several nerves in the arm, and each may be subject to pressure at several spots. For more info, check the Numbness and Tingling page.

Cornell University just made a robot hand with a soft touch. it is not just soft, but it can also sense the shape and texture of what it comes into contact with.
Welcome to the growing field of soft robotics.

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.

Sports related injuries can be the result of a single trauma or due to repetitive overuse. Certain sports such as boxing, basketball, and volleyball have greater risk of injury to the bones, ligaments and muscles of the hand and wrist.
One common injury is a boxer’s fracture, which is a fracture of one of the metacarpal bones: it happens when your punch lands wrong.
Basketball and volleyball players frequently get ‘jammed’ fingers. This happens with a forceful encounter with the ball. There may be visible misalignment of the finger. A jammed finger can be anything from an innocent sprain to a bad fracture-dislocation requiring urgent surgery.
Looks can be deceiving and these injuries should never be underestimated.It is easy but costly to dismiss a serious injury. If pain and swelling do not go away in reasonable time, you should seek medical attention including proper x-rays.
Appropriately sized, and well applied hand wraps and/or gloves protect the hands from such injuries, and proper training is essential to prevent such injuries. Some of these injuries come with an easy fix while others require surgery and dedicated hand therapy.
While still recovering, you may still work on staying in shape and game ready by running, working on lower body and strengthening your core.Your treating physician, together with your therapist, will set the schedule and time frame towards full use and will let you know when it is safe to start exercising your injured hand.If you do too much too soon and push through pain, you may be delaying your recovery or reversing the outcome of your treatment.

My patient showed me today a neat trick to cover up the sharp edges of a Fiberglass cast.
She simply used a glue gun. The glue holds very well. In this case, for over a week. The edges are soft and it holds well to fiberglass. No more catching on clothes. She has not tried it close to her skin, and if you do want to try it, be careful not to burn yourself.
