New AI tool predicts Parkinson’s disease with 96% accuracy — 15 … – Study Finds
In 1991, the world was shocked to learn actor Michael J. Fox had been diagnosed with Parkinsons disease.
He was just 29 years old and at the height of Hollywood fame, a year after the release of the blockbuster Back to the Future III. This week, documentary Still: A Michael J. Fox Movie will be released. It features interviews with Fox, his friends, family and experts.
Parkinsons is a debilitating neurological disease characterized by motor symptoms including slow movement, body tremors, muscle stiffness, and reduced balance. Fox has already broken his arms, elbows, face and hand from multiple falls.
It is not genetic, has no specific test and cannot be accurately diagnosed before motor symptoms appear. Its cause is still unknown, although Fox is among those who thinks chemical exposure may play a central role, speculating that genetics loads the gun and environment pulls the trigger.
In research published today in ACS Central Science, we built an artificial intelligence (AI) tool that can predict Parkinsons disease with up to 96% accuracy and up to 15 years before a clinical diagnosis based on the analysis of chemicals in blood.
While this AI tool showed promise for accurate early diagnosis, it also revealed chemicals that were strongly linked to a correct prediction.
Parkinsons is the worlds fastest growing neurological disease with 38 Australians diagnosed every day.
For people over 50, the chance of developing Parkinsons is higher than many cancers including breast, colorectal, ovarian and pancreatic cancer.
Symptoms such as depression, loss of smell and sleep problems can predate clinical movement or cognitive symptoms by decades.
However, the prevalence of such symptoms in many other medical conditions means early signs of Parkinsons disease can be overlooked and the condition may be mismanaged, contributing to increased hospitalization rates and ineffective treatment strategies.
At UNSW we collaborated with experts from Boston University to build an AI tool that can analyze mass spectrometry datasets (a technique that detects chemicals) from blood samples.
For this study, we looked at the Spanish European Prospective Investigation into Cancer and Nutrition (EPIC) study which involved over 41,000 participants. About 90 of them developed Parkinsons within 15 years.
To train the AI model we used a subset of data consisting of a random selection of 39 participants who later developed Parkinsons. They were matched to 39 control participants who did not. The AI tool was given blood data from participants, all of whom were healthy at the time of blood donation. This meant the blood could provide early signs of the disease.
Drawing on blood data from the EPIC study, the AI tool was then used to conduct 100 experiments and we assessed the accuracy of 100 different models for predicting Parkinsons.
Overall, AI could detect Parkinsons disease with up to 96% accuracy. The AI tool was also used to help us identify which chemicals or metabolites were likely linked to those who later developed the disease.
Metabolites are chemicals produced or used as the body digests and breaks down things like food, drugs, and other substances from environmental exposure.
Our bodies can contain thousands of metabolites and their concentrations can differ significantly between healthy people and those affected by disease.
Our research identified a chemical, likely a triterpenoid, as a key metabolite that could prevent Parkinsons disease. It was found the abundance of triterpenoid was lower in the blood of those who developed Parkinsons compared to those who did not.
Triterpenoids are known neuroprotectants that can regulate oxidative stress a leading factor implicated in Parkinsons disease and prevent cell death in the brain. Many foods such as apples and tomatoes are rich sources of triterpenoids.
A synthetic chemical (a polyfluorinated alkyl substance) was also linked as something that might increase the risk of the disease. This chemical was found in higher abundances in those who later developed Parkinsons.
More research using different methods and looking at larger populations is needed to further validate these results.
Every year in Australia, the average person with Parkinsons spends over $14,000 in out-of-pocket medical costs.
The burden of living with the disease can be intolerable.
Fox acknowledges the disease can be a nightmare and a living hell, but he has also found that with gratitude, optimism is sustainable.
As researchers, we find hope in the potential use of AI technologies to improve patient quality of life and reduce health-care costs by accurately detecting diseases early.
We are excited for the research community to try our AI tool, which is publicly available.
This research was performed with Mr Chonghua Xue and A/Prof Vijaya Kolachalama (Boston University).

Why C3.ai, Palantir, and Other AI Stocks Soared This Week – The Motley Fool
What happened
Stocks have been generally higher over the past week, even as investors considered the ongoing debt ceiling debate and what it means for the future of the broader market. In recent days, market participants have focused on advancements in artificial intelligence (AI) and what opportunities that represents for investors.
With that as a backdrop, C3.ai (AI -5.74%) jumped 35.9% this week, Palantir Technologies (PLTR -0.26%) rose 21.9%, and SoundHound AI (SOUN -3.53%) jumped 13.7% as of 1:30 p.m. ET on Thursday.
Preliminary earnings results from C3.ai and announcements made during Alphabet's (GOOG -0.22%) (GOOGL -0.06%) 2023 I/O developer conference helped boost much of the sector this week, while Palantir Technologies and SoundHound AI basked in the glow of last week's financial results.

C3.ai sported the biggest gains over the past week after the company reported preliminary results that were far better than expected. Management said that for its 2023 fiscal fourth quarter (ended April 30), revenue will be in a range of $72.1 million to $72.4 million, or essentially flat year over year at the midpoint.
While this might not seem like a reason to celebrate, C3.ai was previously expecting revenue to decline roughly 2% at the midpoint of its guidance. The preliminary results also exceeded analysts' consensus estimates, which were calling for revenue of $71.3 million. Furthermore, in the face of mounting losses, the company said it expected to be free cash flow positive, an important step toward consistent profits.
Alphabet also helped fuel excitement for all things AI this week, on the heels of the company's 2023 I/O developer conference last week. Google announced a litany of AI-backed products and services, the headline of which was the company's new and improved large language model, which will form the foundation for its generative AI ambitions and result in an upgrade for Bard, Google's next-generation chatbot.
The search giant also revealed plans to deeply integrate next-generation AI into a broad cross-section of its products and services. These include AI-assisted features coming to Google Docs and Maps, a photo-editing tool for Google Photos, and Help Me Write, which will help compose draft messages in Gmail.
Palantir and SoundHound AI investors continued to revel in the wake of their companies' respective financial results last week.
On May 9, Palantir reported results that exceeded analysts' consensus estimates and the company's own guidance. However, it was management commentary from the AI-based data analytics company that turned heads. CEO Alex Karp said, "We now anticipate that we will remain profitable each quarter through the end of the year," a welcome and unexpected development. Further bolstering investor sentiment, Karp noted, "The depth of engagement with and demand for our new Artificial Intelligence Platform is without precedent."
SoundHound AI released its first-quarter financial report on May 11, and investors welcomed the results. The conversational AI specialist reported revenue of $6.7 million, up 56% year over year, while also reducing its losses, both sequentially and year over year.
Again, it was management commentary that helped fuel investor excitement. "The incredible surge in demand for conversational AI is giving SoundHound a unique advantage," said CEO Keyvan Mohajer. He went on to note that the company offers "the most powerful voice assistant available today," making it a go-to for businesses looking to harness chatbot technology.
Data by YCharts
It's easy to get caught up in all the hype surrounding AI in general, and the recent advances in generative AI in particular. All three of these AI-related stocks have gotten a boost this year, fueled by the excitement surrounding the industry.
However, both C3.ai and SoundHound AI are currently unprofitable, and all three stocks sport valuations that would send any value investor running. SoundHound AI, Palantir Technologies, and C3.ai are currently selling for 14 times, 12 times, and 11 times sales, when a reasonable price-to-sales ratio is between 1 and 2.
The potential opportunity for AI remains vast, and there will likely be many winners in the months and years ahead. That said, investors should approach AI-centric stocks with caution, since it may take time for the reality to catch up to the current hype.
Suzanne Frey, an executive at Alphabet, is a member of The Motley Fool's board of directors. Danny Vena has positions in Alphabet and Palantir Technologies. The Motley Fool has positions in and recommends Alphabet and Palantir Technologies. The Motley Fool recommends C3.ai. The Motley Fool has a disclosure policy.

AI poses risk to humanity, according to majority of Americans in new poll – Ars Technica

A majority of Americans believe that the rise of artificial intelligence technology could put humanity's future in jeopardy, according to a Reuters/Ipsos poll published on Wednesday. The poll found that over two-thirds of respondents are anxious about the adverse effects of AI, while 61 percent consider it a potential threat to civilization.
The online poll, conducted from May 9 to May 15, sampled the opinions of 4,415 US adults. It has a credibility interval (a measure of accuracy) of plus or minus two percentage points.
The poll results come amid the expansion of generative AI use in education, government, medicine, and business, triggered in part by the explosive growth of OpenAI's ChatGPT, which is reportedly the fastest-growing software application of all time. The application's success has set off a technology hype race among tech giants such as Microsoft and Google, which stand to benefit from having something new and buzzy to potentially increase their share prices.
Fears about AI, justified or not, have been rumbling through the public discourse lately due to high-profile events such as the "AI pause" letter and Geoffery Hinton resigning from Google. In a recent high-profile case of AI apprehension, OpenAI CEO Sam Altman testified before US Congress on Tuesday, expressing his concerns about the potential misuse of AI technology and calling for regulation that, according to critics, may help his firm retain its technological lead and suppress competition.
Lawmakers seem to share some of these concerns, with Sen. Cory Booker (D-NJ) observing, "There's no way to put this genie in the bottle. Globally, this is exploding," Reuters reported.
This negative scare messaging seems to be having an impact. Americans' fears over AI's potential for harm far outweigh optimism about its benefits, with those predicting adverse outcomes outnumbering those who don't by three to one. "According to the data, 61% of respondents believe that AI poses risks to humanity, while only 22% disagreed, and 17% remained unsure," wroteReuters.
The poll also revealed a political divide in perceptions of AI, with 70 percent of Donald Trump voters expressing greater concern about AI versus 60 percent of Joe Biden voters. Regarding religious beliefs, evangelical Christians were more likely to "strongly agree" that AI poses risks to human civilization, at 32 percent, compared to 24 percent of non-evangelical Christians.
Reuters reached out to Landon Klein, director of US policy of the Future of Life Institute, which authored the open letter that asked for a six-month pause in AI research of systems "more powerful" than GPT-4. "It's telling such a broad swatch of Americans worry about the negative effects of AI," Klein said. "We view the current moment similar to the beginning of the nuclear era, and we have the benefit of public perception that is consistent with the need to take action."
Meanwhile, another group of AI researchers led by Timnit Gebru, Emily M. Bender, and Margaret Mitchell (three authors of a widely cited critical paper on large language models) say that while AI systems are indeed potentially harmful, the prevalent worry about AI-powered apocalypse is misguided. They prefer to focus instead on "transparency, accountability, and preventing exploitative labor practices."
Another issue with the poll is that AI is a nebulous term that often means different things to different people. Almost all Americans now use "AI" (and software tools once considered "AI") in our everyday lives without much notice or fanfare, and it's unclear if the Reuters/Ipsos poll made any attempt to make that type of distinction for its respondents. We did not have access to the poll methodology or raw poll results at press time.
Along those lines, Reuters quoted Ion Stoica, a UC Berkeley professor and co-founder of AI company Anyscale, pointing out this potential contradiction. "Americans may not realize how pervasive AI already is in their daily lives, both at home and at work," he said.

Shell to use new AI technology in deep sea oil exploration – Reuters
NEW YORK, May 17 (Reuters) - Shell Plc (SHEL.L) will use AI-based technology from big-data analytics firm SparkCognition in its deep sea exploration and production to boost offshore oil output, the companies said on Wednesday.
SparkCognition's AI algorithms will process and analyze large amounts of seismic data in the hunt for new oil reservoirs by Shell, the largest oil producer in the U.S. Gulf of Mexico.
"We are committed to finding new and innovative ways to reinvent our exploration ways of working," Gabriel Guerra, Shell's vice president of innovation and performance, said in a statement.
The goal is to improve operational efficiency and speed, and increase production and success in exploration. The new process can shorten explorations to less than nine days from nine months, the companies said.
"Generative AI for seismic imaging can positively disrupt the exploration process and has broad and far-reaching implications," said Bruce Porter, chief science officer for Austin, Texas-based SparkCognition.
The technology would generate subsurface images using fewer seismic data scans than usual, helping with deep sea preservation, the companies said. Seismic technology sends sound waves to explore subsurface areas.
Fewer seismic surveys accelerate exploration workflow and would save costs in high-performance computing, they added.

Tom Hanks: I could appear in movies after death with AI technology – BBC
16 May 2023

Hanks said: "I could be hit by a bus tomorrow and that's it, but performances can go on and on"
Tom Hanks has raised the prospect of his career continuing after his death using artificial intelligence.
The Forrest Gump and Cast Away actor said the technology could be used to recreate his image, ensuring he continued to appear in movies "from now until kingdom come".
But he admitted the developments posed artistic and legal challenges.
His remarks came as the Pet Shop Boys' Neil Tennant said AI could be used by musicians to complete songs.
"This has always been lingering," he said. "The first time we did a movie that had a huge amount of our own data locked in a computer - literally what we looked like - was a movie called The Polar Express.
"We saw this coming, we saw that there was going to be this ability to take zeros and ones from inside a computer and turn it into a face and a character. That has only grown a billion-fold since then and we see it everywhere."
The Polar Express, released in 2004, was the first film entirely animated using digital motion-capture technology.

Hanks said talks are being held in the film industry about how to protect actors from the effects of the technology.
"I can tell you that there is discussions going on in all of the guilds, all of the agencies, and all of the legal firms in order to come up with the legal ramifications of my face and my voice and everybody else's being our intellectual property," Hanks added.
"What is a bona fide possibility right now is, if I wanted to, I could get together and pitch a series of seven movies that would star me in them in which I would be 32 years old from now until kingdom come.
"Anybody can now recreate themselves at any age they are by way of AI or deep fake technology. I could be hit by a bus tomorrow and that's it, but performances can go on and on and on and on.
"Outside the understanding of AI and deep fake, there'll be nothing to tell you that it's not me and me alone.
"And it's going to have some degree of lifelike quality. That's certainly an artistic challenge but it's also a legal one."

Harrison Ford was "de-aged" for Indiana Jones: The Dial of Destiny
Similar technology has already been used in the latest Indiana Jones film, for which Harrison Ford, 80, was "de-aged" for the opening sequence.
Filmmakers trawled archived material of the younger Ford before matching it to new footage, creating the illusion of Indiana Jones in 1944.
Hanks acknowledged that the technological developments could lead to an AI-generated version of himself appearing in films he may not not normally choose.
He said: "Without a doubt people will be able to tell [that it's AI], but the question is will they care? There are some people that won't care, that won't make that delineation."
AI is also posing dilemmas for the music industry, with conflicting reactions to its use to make music by artists.
A song created using the cloned voices of Drake and The Weeknd was pulled from streaming services last month, but Grimes has encouraged musicians to use her voice to make music.
Pet Shop Boys' singer Neil Tennant told the Radio Times he was excited about the potential of the technology.
"There's a song that we wrote a chorus for in 2003 and we never finished because I couldn't think of the verses, " he said.
"But now with AI you could give it the bits you've written, press the button and have it fill in the blanks. You might then rewrite it but it would be a tool."
