A picture is worth 1,000 words, as the saying goes, and now a startup called Nuralogix is taking this idea to the next level: soon, a selfie will be able give you 1,000 diagnostics about the state of your health.
Anura, the company’s flagship health and wellness app, takes a 30-second selfie and uses the data from that to create a catalogue of readings about you. They include vital stats like heart rate and blood pressure; mental health-related diagnostics like stress and depression levels; details about your physical state like body mass index and skin age; your level of risk for things like hypertension, stroke and heart disease; and biomarkers like your blood sugar levels.
Some of these readings are more accurate than others and are being improved on over time. Just today, to coincide with CES in Vegas — where I came across the company — Nuralogix announced that its contactless blood pressure measurements were becoming more accurate, specifically with accuracy corresponding to a standard deviation of error of less than 8mmHg.
Anura’s growth is part of a bigger trend in the worlds of medicine and wellness. The Covid-19 pandemic gave the world a prime opportunity to use and develop more remote health services, normalizing what many had thought of as experimental or sub-optimal.
That, coupled with a rising awareness that regular monitoring can be key to preventing health problems, has led to a number of apps and devices proliferating the market. Anura is by far not the only one out there, but it’s a notable example of how companies are playing out the equation of relying on low friction to yield big results. That in a way has been the holy grail of a lot of modern medicine — it’s one reason why so many wanted Theranos to be real.
So while some pandemic-era behaviors are not sticking as firmly as people thought they might (e-commerce has not completely replace in-person shopping, for one) observers believe there is a big future in tele-health and companies like Nuralogix providing the means to implement it.
Grandview Research estimates that tele-health was an $83.5 billion market globally in 2022, and that this number will balloon to $101.2 billion in 2023, growing at CAGR of 24% to 2030, when it will be a $455.3 billion market.
The startup — which is based out of Toronto, Canada, and backed by the city’s Mars Innovation effort (a consortium of universities and research groups helping to spin out academic research) and others — uses a B2B business model and counts Japan’s NTT and Spanish insurance provider Sanitas among its customers. It’s also talking to automotive companies that see the potential of being able to use this to track, say, when a driver is getting tired and distracted, or having a health crisis of some other kind.
Right now, the results that Anura comes up with are positioned as guidance — for “investigational” insights that complement other kinds of assessments. The company is compliant with HIPAA and other data protection regulations, and it’s currently going trough the process of FDA approval so that its customers can use the results in a more proactive manner.
It also has a Lite version of the application (on iOS and Android) where individuals can get some — but not all — of these diagnostics.
The Lite version is worth looking at not just as a way for the company to publicize itself, but how it gathers data.
Nuralogix built Anura on the back of an AI that was trained on data from some 35,000 of different users. A typical 30-second video image of a user’s face is analyzed to see how blood moves around it. “Human skin is translucent,” the company notes. “Light and its respective wavelengths are reflected at different layers below the skin and can be used to reveal blood flow information in the human face.”

That in turn is matched up with different diagnostics from those people using traditional measuring tools, and uploaded to the company’s “DeepAffex” Affective AI engine. Then users of the Anura app are essentially “read” based on what the AI has been trained to see: blood moving in one direction or another, or a person’s skin color, can say at lot about how the person is doing physically and mentally.
DeepAffex is potentially being used for more than just tele-health diagnostics. Previous to its pivot to health, company’s AI technology and using this technique of “transdermal optical imaging” (shortened to TOI by the company) to “read” faces, was being applied to reading users’ emotions. One potential application of that was using the tech to augment or even replace traditional lie detector tests, which are regularly used by police and others to determine whether a person is representing things truthfully, but have been proven to be flawed.
There are also horizons that extend into hardware. The current version of Anura is based an app that you access via smartphones or tablets, but longer term the company might also work on their own scanning devices to add in other kinds of facial scanning and other tools such as infrared to pick up even more information and produce more diagnostics. (One area for example that’s not currently touched is blood oxygen, an area that the company definitely wants to tackle.)
I tried out the full version of the Anura app this week in Las Vegas and have to say it’s a pretty compelling experience and indeed is low-friction enough to likely catch on with a lot of people. (And as a measure of that, the company’s demo had a permanent queue of people waiting to try it out.)

People in Europe ate seaweed for thousands of years before it largely disappeared from their diets – we wonder why?
The decline of seaweed as part of the staple diet in Europe remains a mystery.

How are we sure people ate seaweed?
We identified several types of molecules in the dental calculus that collectively are characteristic of seaweed. We refer to these as “biomarkers”. They include a set of chemical compounds called alkylpyrroles. When we detect these compounds together in calculus, we can be fairly sure where they came from. The same goes for other compounds characteristic of seaweed and freshwater plants. To have become embedded in dental calculus, the seaweed and freshwater plants had to have been in the mouth and most probably chewed. Biomarkers do not survive in all our samples, but where they do, they’re found consistently across many individuals we analysed from different places. This suggests seaweed was probably a routine part of the diet.Perceptions of seaweed
Today, seaweed is often seen as the scourge of beaches. It accumulates at the high-water mark where it can create a slippery and sometimes smelly barrier to the sea. But it is a wondrous world of its own. There are over 10,000 species of seaweed worldwide living in the intertidal zone (where the ocean meets the land between high and low tides) and the subtidal zone (a region below the intertidal zone that is continuously covered by water). Around 145 of these species are eaten today and in parts of Asia it is commonplace. Seaweed is edible, nutritious, sometimes medicinal, abundant and local. Although overconsumption can cause iodine toxicity, there are no poisonous intertidal species in Europe. It is also available all year round, which would have been particularly useful in the past, when food supplies were less reliable.Reconstructing ancient diets
Reconstructing ancient diets is challenging and is generally more difficult as you go back in time. This helps explain why we’ve only just realised how much seaweed was being eaten by ancient Europeans. In archaeology, evidence for ancient diets often comes from physical remains: animal bones, fish bones and the hard parts of shellfish. Evidence for plants as part of the diet before farming, however, is rare. Techniques to study molecules from archaeological remains have been around for some time. A key method is known as carbon/nitrogen (C and N) stable isotope analysis. This is widely used to reconstruct ancient human and animal diets based on the relative proportions of these elements in bone collagen. But the presence of plants has been difficult to identify, due to their low nitrogen content. Their presence is masked by an overwhelming signal for animals and fish.Hiding in plain sight
The evidence for seaweed had been present all along, but unrecognised. Our discovery provides a perfect example of how perceptions of what we regard as food influence interpretations of ancient practices. Seaweed was detected in chunks that had been chewed (and presumably spat out) at the 12,000-year-old site of Monte Verde, Chile. But when it is found at archaeological sites, it is more commonly interpreted as having been used for things other than food, such as fuel and food wrappings. In European archaeology, there is a longstanding perception that Mesolithic hunter-gatherers ate lots of seafood, but that when people started farming, they focused on food sourced from land, such as their livestock. Our findings hammer another nail into the coffin of this theory. Today, only a few traditional recipes remain, such as laverbread made from the seaweed species Porphyra umbilicalis in Wales. It’s still not clear why seaweed declined as a staple source of food in Europe after the Middle Ages.What are the implications?
Our unexpected discovery changes the way we understand past people. It also alters our perceptions of how they understood the landscape and how they exploited local resources. It suggests, not for the first time, that we vastly underestimate ancient people. They had a knowledge, particularly about the natural world, that is difficult for us to imagine today. The finding also reminds us that archaeological remains are minute windows into the past, reinforcing the care required when developing theories based on limited evidence. The consumption of plants, upon which our world depends, has been habitually left out of dietary theories from our pre-agrarian past. Rigid theories have sometimes forgotten that humans were behind these archaeological cultures – and that they were probably similar to us in their curiosity and needs. Today seaweed sits, largely unused as food, on our doorstep. Making the edible species a bigger component of our diets could even contribute to making our food supplies more sustainable.

EUR/AUD bearish breakdown supported by additional China fiscal stimulus and AU inflation

- Weak PMI readings from the Eurozone, an increase in China’s budget deficit ratio, and renewed inflationary pressures in Australia may trigger a persistent bearish sentiment loop in EUR/AUD.
- Watch the key short-term resistance at 1.6700 for EUR/AUD.
- A break below 1.6250 key medium-term support on the EUR/AUD may trigger a multi-week bearish impulsive down move.
The Euro (EUR) tumbled overnight throughout the US session as it erased its prior gains against the US dollar recorded on Monday, 23 October; the EUR/USD shed -104 pips from yesterday’s intraday high of 1.0695 to close the US session at 1.0591, its weakest performance in the past seven sessions.
Yesterday’s resurgence of the USD dollar strength has been attributed to a robust set of October flash manufacturing and services PMI data from the US in contrast with weak readings seen in the UK and Eurozone that represented stagflation risks.
Interestingly, the Aussie dollar (AUD) has outperformed the US dollar where the AUD/USD managed to squeeze out a minor daily gain of 21 pips by the close of yesterday’s US session. The resilient movement of the AUD/USD has been impacted by positive news flow out from China, Australia’s key trading partner.
China’s national legislature has just approved a budgetary plan to raise the fiscal deficit ratio for 2023 to around 3.8% of its GDP which was above the initial 3% set in March and set to issue additional sovereign debt worth 1 trillion yuan in Q4. This latest round of additional fiscal stimulus suggests that China’s top policymakers are expanding their initial targeted measures to address the ongoing severe liquidity crunch in the domestic property market as well as to reverse the persistent weak sentiment inherent in the stock market.
In addition, the latest set of Australia’s inflation data surpassed expectations has also reinforced another layer of positive feedback loop in the Aussie dollar which in turn may put Australia’s central bank, RBA on a “hawkish guard” against cutting its policy cash rate too soon.
The less lagging monthly CPI Indicator has risen to an annualized rate of 5.6% in September, above consensus estimates of 5.4%, and surpassed August’s reading of 5.2% which has translated into a second consecutive month of uptick in inflationary growth.
In the lens of technical analysis, a potential bearish configuration setup has emerged in the EUR/AUD cross pair from a short to medium-term perspective.
Major uptrend phase of EUR/AUD is weakening

Even though the price actions of the EUR/AUD have been oscillating within a major ascending channel since its 25 August 2023 low of 1.4285 and traded above the key 200-day moving average so far, the momentum of this up movement is showing signs of bullish exhaustion.
Yesterday (24 October) price action ended with a daily bearish reversal “Marubozu” candlestick coupled with the daily RSI momentum indicator that retreated right at a significant parallel resistance in place since March 2023 at the 65 level which suggests a revival of medium-term bearish momentum.
EUR/AUD bears are now attacking the minor ascending support

The EUR/AUD has now staged a bearish price action follow-through via the breakdown of its minor ascending support from its 29 September 2023 low after a momentum bearish breakdown that was flashed earlier yesterday (24 October) during the European session as seen from the 4-hour RSI momentum indicator.
Watch the 1.6700 key short-term pivotal resistance (also the 50-day moving average) for a further potential slide toward the intermediate supports of 1.6460 and 1.6320 in the first step.
On the other hand, a clearance above 1.6700 invalidates the bearish tone to see the next intermediate resistance coming in at 1.6890.
