But there's one thing that, as he puts it, scared the shit out of him: needles. His aversion was severe enough to hold him back from getting routine tests. Stokes, now 40, recalls an instance in his 20s when he simply couldn't bring himself to get a blood test. He once even drove to the testing facility to get his blood drawn, but couldn't follow through with it. His partner (now wife) eventually convinced him to get the test, but he remembers it as one of "the most horrific" experiences he's had. "I kind of passed out a little bit along the way, and was sweaty and clammy and all that sort of stuff," he said.

Scientists have developed a tiny 3D-printed microneedle vaccine patch that could offer a pain-free alternative to needles. In trials on mice, it offered a 10-fold greater immune response and a 50-fold greater T-cell and antigen-specific antibody response compared with a needle in the arm. The polymer patch, which is smaller than a 5p coin, needs lower doses and could be mailed to people's homes and self-administered, eliminating the need for trained medical personnel. It also offers an'anxiety-free' vaccination option for people who have a'needle phobia', also known as trypanophobia, which is putting some off getting their Covid jabs. The researchers are yet to conduct clinical trials of the patch on humans, which could pave the way for a new way of administering vaccines in the future.

Question: A friend of mine who has a connection to the Asheville Citizen Times told me that because of the staff shortage in the newsroom, the paper has purchased a software program using artificial intelligence that researches and then generates the answers to about half of the Answer Man columns. From what I've heard, this is being done to provide the Answer Man more time to work on other writing assignments. Apparently, the only part of the AI questions that are actually addressed by the real Answer Man are the smart aleck answers, because the AI program is not that developed. Could you please provide some additional information on how this is going? My answer: You've got to admit it would be nice to have some intelligence in this column.

The onset of Covid-19 spurred plenty of discussion and debate around topics such as cleanliness and contactless everything, but it also highlighted the growing role of AI automation. From leveraging AI to help diagnose Covid-19 and take on delivery coordination, to automating customer service its presence has been far more visible. Add to that economic cost savings pressures and companies will almost certainly expand the role of AI post-pandemic at a breakneck pace. Despite widespread phobias centered around AI taking jobs, its implementation will be overwhelmingly beneficial for employees and even save lives. A World Economic Forum (WEF) report stated that, although 75 million jobs are expected to be replaced by AI over the next three years, 133 million new roles will be created – a net gain of 58 million new jobs.

There is a general debate going on how ethical or unethical the use of AI is, however not many people are talking about the challenges in adoption of AI by Small and Medium-sized enterprises. So, before we go one pondering about how people will lose their jobs due to AI, or before we actually start looking for new careers without actually knowing what AI is about, let me take you through a few challenges we are facing in the implementation of Machine learning and Deep learning programs and apps developed on AI platforms, in the real world especially by the majority of businesses around the globe. AI phobia is not a new kind of fear, it is a fear which we have been living with all our lives due to the irrational works of fiction writers and movies. This fear has been around long before the technology was even developed if you have watched movies like Terminator, you know exactly what I am talking about. This phobia is so rampant that even great minds like Stephen Hawkings and Elon Musk have been very vocal about their irrational fear of AI.

Researchers at the University of Cambridge have discovered a way to remove specific fears from the brain using a combination of artificial intelligence and brain scanning technology. Fear related disorders effect around 19 million US adults, or 8.7 percent of the adult population. Current treatments are limited to expensive and'unpleasant' forms such as aversion therapy, where individuals confront their fear by being exposed to it in the hope they will learn that the thing they fear isn't harmful after all. Now a team of neuroscientists from University of Cambridge, Japan and the USA, has found a way of unconsciously removing a fear memory from the brain. Using AI, the team developed a method to read and identify fear memory using'Decoded Neurofeedback'.

Imagine a library of fear. Lining its aisles aren't photo albums of snakes and plummeting aircraft, but are instead volumes containing cross-sectional scans of human brains. They are familiar fMRI images of folded grey matter and feature red-yellow flames of neural activity. In the fear library, these flames vary volume to volume and fear to fear. Different fears feature unique, consistent signatures in the brain, which is the fact that allows them to be so neatly cataloged.

Whether it is a phobia of spiders or a traumatic event in the past, the effects of fear can reverberate through a person's life. But with the right training we can rid ourselves of them, according to a study. Researchers have found a method for tricking the brain into letting go of specific fears, which they claim could lead to new treatments for phobias and post-traumatic stress disorder (PTSD). By combining functional brain imaging with artificial intelligence, researchers have been able to zero in on memories related to fear and retrain them. For people suffering from phobias, a common course of treatment is aversion therapy, bringing someone into contact with their fear. In the case of spiders, a person could be gradually introduced to the arachnids through photos, images and eventually the real thing, learning that their fear is far greater than any actual risk a spider poses.
