Hi Friends,

Today we are going to learn about:

Medical advancements such as 3D printed organs, robot surgeries, high-tech diseased detecting toilets, and a tumor sensing knife
ChatGPT gets banned for lying in court - no longer can lawyers use it to draft court filings because often times, it will make up information that feeds certain biases.
Augmented and virtual reality innovations now include a feature to smell and soon to taste as well

3D Printed Organs, Tumor Sensing Knives, and More!

The advent of autonomous surgical robots is becoming a reality, as exemplified by Johns Hopkins University's Smart Tissue Autonomous Robot. Capable of performing surgeries unaided, the robot is equipped with 3D vision and machine learning, and has already successfully performed a laparoscopic procedure on porcine-tissue models. Meanwhile, smart toilets are being developed to monitor and detect diseases; Withings' U-Scan urinalysis device, for instance, analyzes biomarkers in urine and tracks hormonal fluctuations in women.

In other innovative healthcare advances, the use of VR therapy has shown promising results. A study published in The Lancet revealed that a VR therapy developed by the University of Oxford and Oxford VR was more effective than standard therapy in reducing agoraphobia symptoms. On the bioengineering front, a woman in Texas received the first 3D-printed outer ear implant, made from her own harvested cartilage cells. In the realm of monitoring, Australian and Iraqi engineers have created contact-free monitors for blood pressure, temperature, and oxygen saturation. Half a million physicians are using speech recognition software for medical documentation, and a recent update from Nuance now allows for automatic clinical note generation during appointments. Portable MRI scanners are also emerging, with Hyperfine's Swoop offering a more cost-effective, though lower resolution, alternative to conventional MRI scanners. Lastly, the iKnife, an intelligent surgical instrument developed by researchers at Imperial College London, uses an electrosurgical blade and mass spectrometer to 'smell' tumors with a high diagnostic accuracy rate.

ChatGPT likes to lie in court.

A Texas district judge has issued an order prohibiting the use of generative artificial intelligence for drafting court filings without human oversight, in response to rising use of such technology in legal settings despite known flaws, including fabricating information. Judge Brantley Starr's order mandates that attorneys must certify that any documents partially drafted by AI, such as ChatGPT, Harvey.AI, or Google Bard, have been verified for accuracy by a human using reliable sources. The ruling comes after an incident where a Manhattan lawyer, Steven A. Schwartz, used ChatGPT to write a court brief citing non-existent cases, which the judge could not verify.

The use of large language models (LLMs), like ChatGPT, has been a subject of concern due to their tendency to generate inaccurate or fabricated information, also known as hallucination. Microsoft researchers, in a study accompanying the release of GPT-4, emphasized that these AI models can generate false information, can't verify the consistency of their output with their training data, and can inherit biases from the training data. They also underscored that AI doesn't swear an oath to uphold the law and represent clients faithfully like human attorneys do, hence it can't be fully trusted. Misinformation spread by AI has been evidenced outside of the courtroom too, such as AI-generated misinformation about an explosion near the Pentagon on Twitter, and fabricated historical events created using AI on Reddit.

A smell feature has now been developed for VR!

Virtual reality (VR) experiences, traditionally reliant on sight and sound, are being advanced to include touch and smell for more immersive experiences. Several companies are already developing haptic devices, like gloves and vests, to enable users to 'feel' virtual environments. Now, researchers at Beihang University in China are focusing on integrating the sense of smell into VR. They published a paper in Nature Communications detailing a wearable interface equipped with an odor generator, designed to produce specific scents during VR experiences. The researchers argue that the integration of scent can make virtual environments more realistic and stimulate emotional and memory responses.

The olfaction interface developed by the team comes in two versions: one that adheres to the skin between the nose and mouth, and a face mask. Both versions use miniaturized paraffin wax containers infused with scents. The face mask variant is more versatile with nine odor generators, while the skin-adherent version has two. The scents are activated via an actuator and heat source that melt the wax, releasing the scent similar to a candle. The researchers have ensured user safety by implementing a design that ventilates warm air and a silicone barrier to prevent direct contact with the skin. However, the team acknowledges challenges to overcome, such as reducing the operating temperature of the interface and programming the odor generators to sync with VR headsets for seamless scent release.
