DNA, our genetic material, normally has the structure of a twisted rope ladder. Experts call this structure a double helix. Among other things, it is stabilized by stacking forces between base pairs. Scientists at the Technical University of Munich (TUM) have succeeded at measuring these forces for the very first time on the level of single base pairs. This new knowledge could help to construct precise molecular machines out of DNA. The researchers published their findings in the journal Science.

Over 60 years ago, the researchers Crick and Watson identified the structure of deoxyribonucleic acid, which is more commonly known as DNA. They compared the double helix to a rope ladder that had been twisted into a spiral. The rungs of this ladder consisted of guanine/cytosine and thymine/adenine base pairs. But what keeps the DNA strands in that spiral structure?

BioBuilder promises a way forward for biology education.

Recent plans to use these techniques to obstruct mosquitoes’ disease-carrying abilities have raised concerns from both experts and the public, and some have even argued that the tool can be used to create biological weapons.

Now, the US Defense Advanced Research Projects Agency has revealed a new program that aims to set a ‘safe course’ for this field, with hopes that their toolkit can work both to support bio-innovation and combat bio-threats.

ABSTRACT. This article discusses the philosophical implications and potential social consequences of two experimental – and at the present moment still widely speculative – topics at the intersection between scientific and medical advances, the human body, the human mind, and the globalized health care sector. Head-Transplanting is a chirurgical endeavor envisaged by the HEAVEN project announced to be practically implemented around 2017 and to be available for routine-use around the mid-2020s by a group of internationally as prominent as disputed transplant surgeons. Mind-Uploading is a procedure currently in the first stages of development to create artificial representations of the human brain and its processes in computers and on the internet.

I cannot wait to see how we can use VR for obtaining additional insights on other central nervous system diseases and disorders such as MS, Dystonia, GBM, etc.

Medical applications for VR continue to spread. Just a few weeks ago I wrote about how Paraplegics can learn to walk again with help from Virtual Reality. Scientists from Tomsk Polytechnic University and the Siberian State Medical University, in Russia, believe that it could be the future of diagnosing neurodegenerative diseases such as multiple sclerosis and Parkinson’s disease.

Methods to diagnosis many of these conditions is accomplished by visual assessment in most parts of Russia. The brain scanning technology such as a CAT scan or MRI to confirm the diagnosis is only available in a handful of cities. The VR system being developed would be cheap and easy to roll out across the country.

Scientists at the Swiss Nanoscience Institute, the University of Basel, and the University Hospital Basel have developed and have been testing a device that can screen people with malignant melanoma for a spcific genetic mutation. About half of malignant melanoma cases involve the BRAF gene that results in rapid cell division and drugs targeting this type of cancer are available. The problem is that without knowing if a patient exhibits the mutation, it is dangerous to prescribe the medications since they will not work and will only cause additional problems.

The new device was used to analyze malignant melanoma tissue samples and to find whether the relevant genetic sequence is present. It relies on microscopic cantilevers, some of which have a coating to which the particular genetic sequence sticks to. Other cantilevers have a coating without the sequence. RNA isolated from the biopsy samples was then introduced into the device and the molecules that stuck to the cantilevers made them bend. This bending can be detected, pointing to the presence of the searched for mutation.

A group of researchers at the University of Tokyo and their collaborators showed that using a virtual reality system to treat phantom limb pain by creating the illusion that patients are moving their absent limbs by will and having them repeat this exercise helped ease their perceived pain.

Iranian researchers built a device that can automatically give injections to patients from distance.
