Those with phobias of needles can now get tattoos without having to worry.
Scientists have developed a way to get a permanent tattoo without going under the needle and suffering through hours of pain.
The new technology is in the form of a skin patch that has microneedles smaller than grains of sand. While it still has “needle” in the name, these microscopic needles are of no comparison to the ordinary needles one would have to endure and the impact is painless and bloodless.

The most widely used methods for transdermal administration of the drugs are hypodermic needles, topical creams, and transdermal patches. The effect of most of the therapeutic agents is limited due to the stratum corneum layer of the skin, which serves as a barrier for the molecules and thus only a few molecules are able to reach the site of action. A new form of delivery system called the microneedles helps to enhance the delivery of the drug through this route and overcoming the various problems associated with the conventional formulations. The primary principle involves disruption of the skin layer, thus creating micron size pathways that lead the drug directly to the epidermis or upper dermis region from where the drug can directly go into the systemic circulation without facing the barrier. This review describes the various potential and applications of the microneedles. The various types of microneedles can be fabricated like solid, dissolving, hydrogel, coated and hollow microneedles. Fabrication method selected depends on the type and material of the microneedle. This system has increased its application to many fields like oligonucleotide delivery, vaccine delivery, insulin delivery, and even in cosmetics. In recent years, many microneedle products are coming into the market. Although a lot of research needs to be done to overcome the various challenges before the microneedles can successfully launch into the market.

Both science fiction and actual science have demonstrated the malleability of memory, from implanting artificial memories to suppressing bad ones. MIT researchers recently added to the body of memory work with their recent publication in Nature about swapping positive and negative memories in lab mice.
Memories are complicated. For one thing, as soon as we experience something, our brains go to work, associating the memory with context, whether it’s emotional or geographical or involving the people surrounding the event. Because memories aren’t exact recordings of what has actually happened (which is what makes eyewitnesses notoriously unreliable), psychologists and scientists have long been toying with it, seeing how they can manipulate people to either create new associations surrounding an event, remember things that had been long buried, or even implant new memories. MIT’s recent study sought to identify the neurological basis for such ideas.

With billions of dollars flooding into longevity, what role will epigenetic clocks play in measuring and intervening in aging?
When Horvath first described epigenetic clocks, scientists began to speculate that altering them could reverse aging. After all, if certain patterns of DNA methylation at certain sites in cells in certain tissues of your body are hallmarks of aging, could shifting them somehow reverse aging?
The world has experienced a technological leap in the last decade. Innovations such as smartphones and tablets, 3D printing, artificial intelligence, and blockchain are coming with us. As is well known, these technologies have become indispensable, not only causing hype in one or the other but also permanently changing our daily lives and ways of working. Will this development slow down? I do not think so, the exact opposite. In the next 10 years, you can expect even more breakthroughs than you can imagine today.
In this programme the world’s leading experts attempt to build an artificial human based on actress Gemma Chan, star of the sci-fi series Humans, for a ground-breaking scientific stunt that will test just how far away we are from ‘synthetic’ humans.
Could science fiction be our reality much sooner than we think?
