Wind farms have traditionally made less money for the electricity they produce because they have been unable to predict how windy it will be tomorrow.
The way a lot of power markets work is you have to schedule your assets a day ahead, said Michael Terrell, the head of energy market strategy at Google. And you tend to get compensated higher when you do that than if you sell into the market real-time.
Well, how do variable assets like wind schedule a day ahead when you don't know the wind is going to blow? Terrell asked, and how can you actually reserve your place in line?
We're not getting the full benefit and the full value of that power.
Heres how: Google and the Google-owned Artificial Intelligence firm DeepMind combined weather data with power data from 700 megawatts of wind energy that Google sources in the Central United States. Using machine learning, they have been able to better predict wind production, better predict electricity supply and demand, and as a result, reduce operating costs.
What we've been doing is working in partnership with the DeepMind team to use machine learning to take the weather data that's available publicly, actually forecast what we think the wind production will be the next day, and bid that wind into the day-ahead markets, Terrell said in a recent seminar hosted by the Stanford Precourt Institute of Energy. Stanford University posted video of the seminar last week.
The result has been a 20 percent increase in revenue for wind farms, Terrell said.
The Department of Energy listed improved wind forecasting as a first priority in its 2015 Wind Vision report, largely to improve reliability: Improve Wind Resource Characterization, the report said at the top of its list of goals. Collect data and develop models to improve wind forecasting at multiple temporal scalese.g., minutes, hours, days, months, years.
Googles goal has been more sweeping: to scrub carbon entirely from its energy portfolio, which consumes as much power as two San Franciscos.
Google achieved an initial milestone by matching its annual energy use with its annual renewable-energy procurement, Terrell said. But the company has not been carbon-free in every location at every hour, which is now its new goalwhat Terrell calls its 24x7 carbon-free goal.
We're really starting to turn our efforts in this direction, and we're finding that it's not something that's easy to do. It's arguably a moon shot, especially in places where the renewable resources of today are not as cost effective as they are in other places.
The scientists at London-based DeepMind have demonstrated that artificial intelligence can help by increasing the market viability of renewables at Google and beyond.
Our hope is that this kind of machine learning approach can strengthen the business case for wind power and drive further adoption of carbon-free energy on electric grids worldwide, said DeepMind program manager Sims Witherspoon and Google software engineer Carl Elkin. In a Deepmind blog post, they outline how they boosted profits for Googles wind farms in the Southwest Power Pool, an energy market that stretches across the plains from the Canadian border to north Texas:
Using a neural network trained on widely available weather forecasts and historical turbine data, we configured the DeepMind system to predict wind-power output 36 hours ahead of actual generation. Based on these predictions, our model recommends how to make optimal hourly delivery commitments to the power grid a full day in advance.
The DeepMind system predicts wind-power output 36 hours in advance, allowing power producers to make ... [+] more lucrative advance bids to supply power to the grid.

New York’s state of mind: Part II — Former TH reporter shares account of COVID-19 in Big Apple – telegraphherald.com
For me, it started with a tickle in my throat, like many minor illnesses begin.
The next day, I knew I was sick achy, raspy-throated and really, really tired. It was a week before I realized I had COVID-19.
For 10 days March 16-26 my symptoms, some familiar and some peculiar, took turns laying me low: One day, a behind-the-eyes headache with burning eyes, and the next day, periodic dizziness and lack of appetite. What I could count on every day was a deep fatigue and not being able to smell or taste anything.
ARTICLE CONTINUES BELOW ADVERTISEMENT
My symptoms gradually subsided, and one day, I realized I felt normal.
The next day, my husband, Clayton Pederson, 66, started feeling funny. For nearly two weeks, he had symptoms similar to mine but with a lingering cough. Then, he, too, got better.
Although we are both in the age range targeted most aggressively by COVID-19 (I am 71), neither of us had its hallmark symptoms fever, deep cough and trouble breathing. We were not sick enough to get tested at the time, although intense testing throughout New York City has been instituted, and we could get a free COVID-19 test down the street from our Bronx apartment.
Instead, we recently went to a CITYMD Urgent Care clinic and got blood draws for COVID-19 antibodies. We both tested positive for coronavirus antibodies, meaning we have developed some amount of immunity for some amount of time. The virus is too new to know much about immunity to it. We continue to follow all safe health guidelines.
We were both sick in the early days of the pandemic in New York City, as all hell broke loose and the country watched horrific scenes from overwhelmed hospitals.
Thankfully, after more than two months of strict social isolation, the cases of new infections, hospital admissions and deaths here have declined almost daily.
As of this writing, the city will count its 200,000th COVID-19 case and nearly 20,000 people have died from the virus.
The pandemic has not devastated New York City equally. While higher-income neighborhoods like in Manhattan have seen lower rates of infection, much higher numbers in the outer boroughs such as the Bronx and Queens have been fueled by poverty and the density of multigenerational households.
Our part of the Bronx, along the Grand Concourse near Yankee Stadium, ranks in about the middle for the number of cases. In our ZIP code alone COVID-19 has killed 256 people.
We moved from Bellevue, Iowa, to be closer to our daughter (pregnant with twins) and her husband and our 6-year-old granddaughter.
For more than two months this spring, due to strict rules set down by New York Gov. Andrew Cuomo as New York Pause, we couldnt see them or any of our friends. We only left our apartment for short walks or to buy groceries, fully masked, gloved and sanitized.
Since our positive antibody test results, we have resumed an abbreviated schedule of nannying our granddaughter. This entails riding two subway lines down to the Upper West Side and back to the Bronx.
New Yorks subways nearly are empty (ridership is down 90% from more than half a million riders daily) and are deep cleaned every night between 1 and 5 a.m. the first time all 36 lines have been shut down. The homeless who sleep on the trains overnight also are removed and offered shelter and services.
I feel two types of deep grief throughout New York City. The most obvious is the pain and suffering caused by so many deaths and internal injuries caused by a virus that struck so hard and so fast, bringing a great city to its knees in a few weeks.
The other grief is just starting to seep into the psyches of millions of natives and newbies alike. Its a broader sadness for a life and a city many fear will never recover as it was. The social fabric has unraveled, fear has replaced trust, whatever future can be imagined is bleak on so many levels.
We help pack up 1,000 meals every Friday to be distributed to hospital workers, other essential workers or anyone who is hungry through World Central Kitchen. There are hundreds of formal and informal food distribution sites around the city since about one of every five working New York City residents has lost their job. One site is on the end of our block and folks start lining up well before it opens once per week.
We continue to social distance, wear face masks and gloves and are ever so grateful that our bouts of COVID-19 were as mild as they were.

Dalai Lama and UW expert share message of hope, determination, and education of the mind – University of Wisconsin-Madison

(Editors Note: The ABC News interview took place before the recent protests against police brutality; the Dalai Lama comments on the protests here.)
Humanity has an opportunity to transform negative emotions like fear and anxiety into determination and compassion for others, according to His Holiness the Dalai Lama. This message of hope is front and center in the Dalai Lamas recent video conversation with Dan Harris, ABC News anchor and co-founder of Ten Percent Happier, and Richard Davidson, University of WisconsinMadison professor and founder of the Center for Healthy Minds.
We are human beings. We are social animals, the 14th Dalai Lama told Harris and Davidson over video from Dharamsala, India. Obviously our own experience of constant fear and constant anger destroys our inner peace. More compassionate feelings bring inner strength and inner peace Helplessness thats a failure our own cost.
The conversation comes at a time when many people around the world are experiencing unprecedented loss, hardship and isolation. Amid the recent events such as the COVID-19 pandemic, the World Health Organization has warned that a global mental health crisis is likely to follow, and many thought-leaders like the Dalai Lama, Harris and Davidson are sharing insights and tools to promote emotional well-being.
For the past 28 years, the leader of Tibetan Buddhism has partnered with scientists, including UWMadisons Davidson, to inspire research on how people can alter their thinking, emotions and behavior toward a kinder, wiser, more compassionate world. Davidson is well-known for his scientific work unearthing the impacts of meditation and other prosocial qualities such as compassion on the brain.
Such evidence along with other research generated by the scientific community has fueled the Dalai Lamas promotion of secular ethics, which are altruistic values deep-seated in human nature that anyone can nurture, regardless of background or religion. The Dalai Lama described mental training, including meditation practice, as a transformative tool that can not only sharpen the mind, but also increase peoples altruism and compassion toward each other.
The Dalai Lama and Davidson have explored how these practices can best serve others and how every human being shares the same wish to be happy and to be free of suffering. Davidson says his aspiration is that someday, mental exercise of this kind will be as commonly practiced as brushing ones teeth. If people took just a few minutes each day to nurture positive qualities of mind, the world would be a very different place.
This is one reason why the Dalai Lama thinks a new form of education is needed that focuses on the mind, emotion and a persons inner world. Often these insights are outcomes of practicing various forms of meditation, and there are numerous tools available online to practice mental training, including Davidsons Healthy Minds Program (led by the nonprofit he founded Healthy Minds Innovations) and Harris meditation platform Ten Percent Happier. Both mobile apps have been offering free meditation practices and mental health tools during the pandemic.
In addition, grief and other negative emotions have overwhelmed many around the world. Harris, who lives in New York City, which has been particularly hard-hit by COVID-19 in the United States, reflected on the different ways grief can take shape. Because of the risks of coronavirus to others and the number of people sick, many people are unable to say goodbye to loved ones. Millions of others are also grieving about losing their previous life, which has been upended by the pandemic.
How can the world process such grief?
The Dalai Lama reiterated that despite the deep sadness, there are glimmers of hope and opportunities to expand care for the whole world.
Taking care of others is actually taking care of yourself, he said, noting that the best way to take care of your own happiness is to take care of ones community.
ABC News Live and Good Morning America recently featured the video conversation and a longer-form interview is available on the Ten Percent Happier podcast.

NewsOpinionColumnistsA controversial list of the top ten Scottish bands ever has a stunned Aidan Smith searching for a pithy putdown.
Tuesday, 2nd June 2020, 7:30 am
The trouble with these surveys of the best this and the all-time-greatest that is theyre wholly subjective. Invariably the pollsters ask the question of other people. Thus the results do not reflect the superior taste, sophistication and critical rigour that you could have brought to the debate and, much more crucially, me.
Usually I accept this, quietly console myself about never having read a Harry Potter book or understood the deeper meaning of a Richard Curtis film, and move on. But, honestly, did you see that list of the best Scottish bands?
If you didnt, here goes, pop-pickers: 1 the Proclaimers, 2 Simple Minds, 3 Deacon Blue, 4 the Blue Nile, 5 Travis, 6 the Waterboys, 7 Runrig, 8 Texas, 9 Belle and Sebastian, 10 Del Amitri.
The survey was conducted by an English-based Sunday newspaper and I cant help wondering who the respondents were. A wide-ranging sample of the Countryside Alliances membership? An exhaustive canvassing of Young Farmers Clubs? Or did the papers property correspondent a vital job at this title ring round a bunch of estate agents? Did the business desk ask its favourite trust fund managers?
But just as I was congratulating myself for these pithy observations at the expense of our dear rivals, a Twitter wag trumped me. Alan Partidges Scotland playlist? wondered Marcus Orlandi.
You remember the bold Alans musical preferences. He would bellow along to some excruciatingly emotive power-ballad in the car, tapping the beat on the steering wheel in string-back driving gloves, hands never wavering from the Ministry of Transport-recommended ten-to-two formation. He would serenade a lady friend by singing something unsingable like Steeleye Spans Gaudete, this hot date foundering shortly afterwards on his shock admission that he understood the function of a vallance. He would, when a young member of staff at his hotel asked Who are Wings?, respond with a superior smirk: Only the band the Beatles could have been.
When I read the ten-best list, I was briefly stunned. Was there no one else? Perhaps not. The Scot who loves music knows not to boast. He or she will be aware that its not just the national football team who like to seize defeat from the jaws of victory. Edinburgh-born Stuart Sutcliffe was as important to the early days of the Beatles as Ian Stewart, son of Pittenweem, was to the nascent Rolling Stones, but both were booted out before the screaming began.
Weve contributed a third of Cream, half of the Eurythmics and when the cry went up, Can anyone play the flute one-legged in a tweed cape and codpiece?, it was a Scot who answered the call (Jethro Tulls Ian Anderson). But bands 100 per cent Caledonian, made out of shortbread and thistles, which were also great? Maybe wed have to make do with Texas, those good ole southern boys and girls from, er, Glasgow.
Oh no we wouldnt. What about the Associates? What about Stealers Wheel? What about Marmalade with their fab 45 Reflections of My Life, the choice of none-more-diverse soundtracks as those for a government TV campaign for the Good Friday Agreement and Linda Lovelaces sex odyssey Deep Throat?
I got in touch with my chum Brian Hogg, author of the Bible All That Ever Mattered: the History of Scottish Rock and Pop and he quickly came up with ten bands of his own: Teenage Fanclub, Jesus and Mary Chain, the Poets, the Incredible String Band, Sensational Alex Harvey Band, Josef K, Fire Engines, the Pastels, the Shop Assistants and Boards of Canada.
Hogg stressed this was his list as of 2.11pm yesterday. His methodology was bands whod made a pivotal contribution to music here or further afield. He signed off: Of course Im now haunted by those that missed the cut...
I think Im going radge
The jock n roll-inclined Twitterati offered their nominations: Orange Juice, Primal Scream, Aztec Camera, Cocteau Twins, Chvrches, Frightened Rabbit, Gallagher & Lyle, the Average White Band (who instead of coals to Newcastle took soul to the USA), Fife contenders Nazareth and the Skids, Fay Fifes combo the Rezillos (I think Im going radge might be the greatest Scottish lyric of all time) and for goodness sakes Franz Ferdinand.
Ah but its all a matter of personal taste. Many of the aforementioned are way cooler than the surveys top ten. The Incredible String Band were the only Scots to play Woodstock (but, in another semi-tragedy, got missed off the movie of the mega-gig). There would be no Guns N Roses without Nazareth to inspire them. I could shout for Clouds, prog pioneers adored by David Bowie. But cultural importance doesnt matter to everyone and wont get you played at a wedding disco, the barometer for some of a favourite band.
Does that make us who take against this list anoraks or snobs or, crikey, fascists or sorry to any female voters simply men of a certain age whove never forgotten when music papers were crucial to our lives? Well, the most disappointing thing about the survey is the lack of diversity. Many of the bands are similar-sounding, possibly remembered from extended sessions at the students union jukebox when it was too wet to venture out to lectures.
Theres a lot of rain. Deacon Blue: Raintown. The Blue Nile: Tinseltown in the Rain. Travis: Why Does It Always Rain on Me? Del Amitri have two songs with rain in the title while Simple Minds sang Come in, come out of the rain. Wet Wet Wets omission is surprising but Im starting to wonder if the poll didnt go much further than Scots TV meteorologists including Carol Kirkwood, Heather the Weather Reid and Peter Slush will be a problem on roads, as will Sloss.
No issue, though, with the Proclaimers being No 1, they of the blissfully rain-free Sunshine on Leith.

Life today is razors-edge tense. If your regular coping methods arent measuring up, there are science-backed actions we can add on our own to ease anxiety, depression and stress all done naturally, no doctors note required.
If you had to choose just one thing to do to betteryour mental and physical health, choose toexercise on a regular basis.
Scientists believe exercise increases blood circulation to the brain, especially areas like the amygdala and hippocampus which both have roles in controlling motivation, mood and response to stress. For one thing, it releases endorphins, the bodys feel-good hormones.
You dont have to do high-intensity exercise to ease stress,according to a studyof university students. Researchers found that exercise of moderate intensity, defined as working out hard enough so you can still talk but cant sing, reduced depression.
High-intensity interval training, however, increased stress and inflammation. Its possible intense exercise could make an already stressed-out system more jittery, especially in individuals who were not accustomed to exercise, said study author Jennifer Heisz inan article she wrote.
Numerous studiesshow the biggest benefits come fromrhythmic exercises, which get your blood pumping in major muscle groups. Those include running, swimming, cycling and walking. Do the exercise for 15 to 30 minutes at least three times a week over a 10-week period or longer at low to moderate intensity.
A brisk walk, jog or bike ride can help keep you calm and healthy during these uncertain times, said Helsz, who is an associate professor in kinesiology at McMaster University in Ontario, Canada.
Theres another benefit of exercise it will improve your sleep quality, one of the best things you can do to ease stress and boost your mood. Theres an additional benefit to a better snooze. Youll beprotecting your heart,improving your brainandreducing your desire to snack.
Its not just about sleeping longer, either. Youre trying to give your body time to go through enough sleep cycles to repair itself, which means going from light sleep to deep and back again. Set yourself up for success bydeveloping good sleep habitsthat will train your brain for restorative sleep.
Develop a routine.You want to teach your body (and brain) to calm down, so try to begin relaxing at least an hour before bedtime. Shut off the news and put down your smartphone. Taking a warm bath or shower, reading a book, listening to soothing music, meditating or doing light stretches are all good options.
You should also have a regular bedtime and a regular time for getting up in the morning, even on weekends, experts said.
Avoid certain food and drink.Avoid stimulants such as nicotine or coffee after midafternoon, especially if you have insomnia. Alcohol is another no-no. You may think it helps you doze off, but you are more likely to wake in the night as your body begins to process the spirits.
Strive for cooler temperatures.Make sure your bed and pillows are comfortable, and the room is cool: Between 60 and 67 degrees is best. Dont watch television or work in your bedroom. You want your brain to think of the room as only for sleep.
Keep yourself in the dark.Be sure to eliminate all bright lights, as even the blue light of cellphones or laptops can be disruptive. If thats hard to accomplish, think about using eye shades and blackout curtains to keep the room dark. But during the day, try to get good exposure to natural light since that will help regulate your circadian rhythm.
Something as simple as taking deep, slow breaths can do amazing things to our brain and therefore our stress, experts said.
Learning breathwork lets you know that you have an ability to physiologically calm yourself, said stress management expert Dr. Cynthia Ackrill, an editor forContentment magazine, produced by theAmerican Institute of Stress.
When you physiologically calm yourself, you actually change your brainwaves, Ackrill said. I used to do neurofeedback, which is brainwave training, and I would have people hooked up to all kinds of machines. And after doing breathwork with them you could see these massive changes in the brain. It also lowered blood pressure.
Deep breathing realigns the stressed-out part of our bodies, called the the sympathetic system, with the parasympathetic, or rest and restore system, Ackrill explained.
While there are many types of breathing, a lot of research has focused on cardiac coherence, where you inhale for six seconds and exhale for six seconds for a short period of time. Focus on belly breathing, or breathing to the bottom of your lungs, by putting your hand on your tummy to feel it move.
Anytime you intentionally bring your attention to your breath and slow it down, youve already done a good thing, Ackrill said. Thats just one simple tool that you can use and it gives you back a feeling of power and control.
And it gives you that pause where you begin to realize that you are separate from whats happening to you, and you can choose a response instead of just a primal reaction.
Yoga, of course, is a form of physical exercise. In additon to releasing endorphins, yoga can regulate the bodys central stress response system, called the hypothalamic-pituitary-adrenal axis, and improves sleep quality, said Jacinta Brinsley, a doctoralcandidate at the University of South Australiawho recently published a study on yoga.
But yoga is also a spiritual discipline, designed to meld body and mind. A yoga lifestyleincorporates physical postures, breath regulation and mindfulness through the practice of meditation.
Yogic philosophy teaches that the body, mind and spirit are all interconnected what you do in one area, for example, a physical exercise to strengthen your leg muscles, will have an effect in all of the other areas of your system, said Laurie Hyland Robertson, the editor in chief of Yoga Therapy Today, a journal published by the International Association of Yoga Therapists.
So we can expect that leg exercise, especially when you approach it in a mindful, purposeful way, to affect not only your quadriceps but also your emotional state, your bodys physiology and even your mental outlook, said Robertson, who coauthored the book Understanding Yoga Therapy: Applied Philosophy and Science for Health and Well-Being.
Two traditional Chinese exercises, tai chi and qi gong, have also been shown to be excellent stress reducers. Both are low-impact, moderate-intensity aerobic exercises that contain a flowing sequence of movements coupled with changes in mental focus, breathing, coordination and relaxation.
Studies have foundthat tai chi and qi gong increase blood levels of endorphins, reduce levels of the stress hormone cortisol and improve immune function, a key benefit in the age of coronavirus. Andbrain scansof people using tai chi and qi gong find increased alpha, beta and theta brain wave activity, suggesting increased relaxation and attentiveness
Meditation and mindfulness are two excellent ways to lower stress.
At theCenter for Healthy Mindsat the University of Wisconsin-Madison, researchers studied the brains of Tibetan Buddhist monks recruited by the Dali Lama and found startling results: Tens of thousands of hours of compassionate meditation had permanently altered the structure and function of the monks brains. One 41-year-old monk had the brain of a 33-year-old.
But you dont have to devote your life to meditation to see change, said Richard Davidson, founder and director of the Center for Healthy Minds, theinstitute thatdid the research on the monks.
Davidson, who is a professor of psychology and psychiatry,pointed to the results of a randomized controlled trial of people whove never meditated before. Using direct measures of brain function and structure, he found itonly took 30 minutes a day of meditation practiceover the course of two weeks toproduce a measurable change in the brain.
When these kinds of mental exercises are taught to people, it actually changes the function and the structure of their brain in ways that we think support these kinds of positive qualities, Davidson said. And that may be key in producing the downstream impact on the body.
One of Davidsons favorite mindfulness exercises cultivates appreciation.
Simply to bring to mind people that are in our lives from whom we have received some kind of help, Davidson said. Bring them to mind and appreciate the care and support or whatever it might be that these individuals have provided.
You can spend one minute each morning and each evening doing this, he said. And that kind of appreciation is something that can foster a sense of optimism about the future.
Like exercise, mindfulness will need to be practiced on a regular basis to keep the brains positive outlook in good shape, Davidson said. But the effort is definitely worth it.
This is really about nurturing the mind, he said. And there is ample evidence to suggest that there are real psychological and physical health-related benefits.

5 natural ways to boost your mental health during stressful times - wreg.com
DeepMind and Google Healthhavedeveloped an AI that can predict wholl get one of the worlds most common causes of blindness.
The system was built to detect age-related macular degeneration (AMD), a disease that afflicts more than 25% of over-60s in Europeand up to 11 million people in the US.
There are two types of the disease: a dry form, which often only causes mild sight loss, and a wet one, which can lead to permanent blindness.
[Read:This AI detects eye disease in newborn babies]
Currently, Ophthalmologists diagnose AMD by analyzing 3D scans of the eye. But these highly detailed images are time-consuming to review.DeepMinds researchers suspected that AI could more quickly detect the symptoms of patients needing urgent treatment which could ultimately save their sight.
The teamtrained their model onan anonymized datasetof retinal scansfrom 2,795 patients who had been diagnosed with wet AMD.
They then used two neural networks to detect the disease by analyzing 3D eye scans and labeling features that offered clues about the diseases. The system uses this data to estimate whether the patient would develop wet ADM within the next six months.
DeepMind claims that the system predicted the onset of wet AMD as well as human experts and in some cases was even more accurate.
Pearse Keane, an ophthalmologist who worked on the project, said the system could act as an early warning sign for the disease:
With this work, we havent solved AMD but I think weve just added another big piece of the puzzle.
The next step is validating the algorithm so it can be used in clinical trials. In time, it could even help doctorsdevelop treatments for the disease.
Published May 19, 2020 17:51 UTC
The proliferation of Artificial Intelligence (AI) in the Healthcare sector is one advancement that is worth a watch. Several major companies including big techs are moving forward in the same direction to revolutionize how care is being given to those in need. Recently, a collaboration between Googles DeepMind and Moorfields Eye Hospital NHS Foundation Trust has come up with a development of an AI model that has the potential to predict whether a patient will develop wet AMD within six months. In the future, this system could potentially help doctors plan studies of earlier intervention, as well as contribute more broadly to the clinical understanding of the disease and disease progression.
Age-related macular degeneration (AMD) is the biggest cause of sight loss in the UK and the USA and is the third-largest cause of blindness across the globe.
Around 75 percent of patients with AMD have an early form called dry AMD that usually has a relatively mild impact on vision. A minority of patients, however, develop the more sight-threatening form of AMD called exudative, or wet AMD. This condition affects around 15 percent of patients and occurs when abnormal blood vessels develop underneath the retina. These vessels can leak fluid, which can cause permanent loss of central vision if not treated early enough.
The researchers trained and tested its AI model using a retrospective, anonymized dataset of 2,795 patients. These patients had been diagnosed with wet AMD in one of their eyes and were attending one of seven clinical sites for regular OCT imaging and treatment. For each patient, the researchers worked with retinal experts to review all prior scans for each eye and determine the scan when wet AMD was first evident. In collaboration with its colleagues at DeepMind, the company developed an AI system composed of two deep convolutional neural networks, one taking the raw 3D scan as input and the other, built on its previous work, taking a segmentation map outlining the types of tissue present in the retina. DeepMinds prediction system used the raw scan and tissue segmentation to estimate a patients risk of progressing to wet AMD within the next six months.
To test the system, the company presented the model with a single, de-identified scan and asked it to predict whether any signs indicated the patient would develop wet AMD in the following six months. DeepMind also asked six clinical expertsthree retinal specialists and three optometrists, each with at least ten years experienceto do the same. Predicting the possibility of a patient developing wet AMD is not a task that is usually performed in clinical practice so this is the first time, that experts have been assessed on this ability.
While clinical experts performed better than chance alone, there was substantial variability between their assessments. DeepMinds system performed as well as, and in certain cases better than, these clinicians in predicting wet AMD progression. This highlights its potential use for informing studies in the future to assess or help develop treatments to prevent wet AMD progression.
Future work could address several limitations of this research. The sample was representative of practice at multiple sites of the worlds largest eye hospital, but more work is needed to understand the model performance in different demographics and clinical settings. Such work should also understand the impact of unstudied factorssuch as additional imaging teststhat might be important for prediction but were beyond the scope of this work.
These findings demonstrate the potential for AI to help improve understanding of disease progression and predict the future risk of patients developing sight-threatening conditions. This, in turn, could help doctors study preventive treatments.
This is the latest stage in DeepMinds partnership with Moorfields Eye Hospital NHS Foundation Trust, a long-standing relationship that transitioned from DeepMind to Google Health in September 2019. The companys previous collaborations include using AI to quickly detect eye conditions, and showing how Google Cloud AutoML might eventually help clinicians without prior technical experience to accurately detect common diseases from medical images.
This is early research, rather than a product that could be implemented in routine clinical practice. Any future product would need to go through rigorous prospective clinical trials and regulatory approvals before it could be used as a tool for doctors. This work joins a growing body of research in the area of developing predictive models that could inform clinical research and trials. In line with this, Moorfields will be making the dataset available through the Ryan Initiative for Macular Research. The researchers hope that models like theirs will be able to support this area of work to improve patient outcomes.

Which trades brought success?
A very large proportion of the profits came from products that make volatility tradable in the markets. It is well known that volatility in the markets reached very extreme levels in March. This is also one of the causes of our drawdown. We already anticipated falling volatility in early March. As volatility continued to rise, our losses grew. We held on to our positions as luckily they werent too large to wipe out our account.

‘This is my deep breath’: New Jersey pro surfer returns to the water in Ventnor for the first time since coronavirus closed the beach – Press of…
As Cassidy McClain zipped up her wetsuit and squeezed her feet into her booties, a familiar sense overcame her.
She lifted her surfboard out of her Hyundai Sonata on May 16 and looked toward the Ventnor pier, the cool sea breeze flowing through her short, sunkissed hair.
She knew this place. This beach was her home, where she found her balance and won a few surfing competitions. But McClain, who grew up in Ventnor and graduated from Atlantic City High School in 2013, hadnt visited in more than a month, since the coronavirus closed the citys beaches and barred all activities, including surfing. That Saturday brought the first decent waves since Ventnor officials said surfing could resume May 13, and the ocean was calling.
It was 7 a.m. as McClain padded down the wooden walkway. The morning sun shone through the clouds, sending orange, gray, and blue streaks across the sky, the Atlantic City Ferris wheel peeking through the hazy horizon. She sank into the sand as she walked toward the shoreline, each step pulling her closer to home. When that first incoming wave rushed across her feet, she stopped and smiled.
After 45 days without surfing the longest this 24-year-old professional surfer had gone without the sport since she started at age 9 she was back.
The first plunge felt euphoric. As she gripped her surfboard and took her first duck dive beneath a wave, the ice cold water was electrifying, sending goose bumps across her skin and recharging her almost instantly. Her face breached through the surface, and for the first time in weeks, she could breath again.
Its a rush that goes through your whole body, said McClain. This is my deep breath.
The waves werent great, but McClain, a Ventnor native, didnt care. The breaks were short and barely rideable, so she had to be fast. One second she was up on her board, twisting in the air on top of the wave. The next, she was down in the water, jumping back on and paddling out on the hunt for the next ride.
It felt different, she said after emerging from her first 45-minute surf. I was a little rusty at first, but then it just felt so good.
McClain, who was named the New Jersey Female Surfer of the Year in 2018, surfs year round she said snow storms give the best swells and travels to places like Australia, Puerto Rico and Barbados to compete and judge competitions. Shes usually only in Ventnor for a few months at a time. But the World Surf League canceled all competitions through June and she returned from Puerto Rico at the end of March, likely for a while.
When she found out the pier was closing, she was shocked.
It was definitely the right call, because there are so many unknowns with the coronavirus, she said, But at the same time, youre taking away something that people use to help with their mental health.
McClains return to the water came after residents pushed Ventnor officials to lift the surf ban, an initiative led by Lou Solomon, a 68-year-old Absecon Island native and Ventnor surfer of 55 years.
Solomon reached out to city officials two weeks ago to make his case about surfing, stressing that other towns, like Margate and Atlantic City, have allowed it. Plus, he said, its a sport of constant movement and surfers are territorial, staying away from each other to catch their own waves, which makes social distancing natural.
The city lifted the ban May 13. There are still some restrictions no waxing boards or changing into wetsuits on the beach but, as Solomon put it, youve gotta start somewhere.
Solomon said he surfed at other towns a few times during the Ventnor shutdown, but it wasnt the same. McClain chose not to, worried about the increased number of surfers being pushed to those areas.
When you live in Ventnor you wanna surf in Ventnor, Solomon said.
Like the Beach Boys say: Catch a wave, and youre sitting on top of the world, he said. Its the highest high when you get a good wave. I feel like a kid again.
Managing the stress of the coronavirus without their outlet was tough. Virtual yoga classes at the Zen Den kept McClain centered.
Im not myself when Im not in the water, she said. I crave the ocean and I cant function without it.
Another Ventnor surfer, Joel Smiler, said no other mental release compares.
Theres more to it than just grabbing a board and surfing, said Smiler, 58, a Delaware County resident with a condo in Ventnor. It becomes mind over matter and body.
There is nothing else to think about other than that wave, he said.
As McClain emerged from the ocean and peeled back her wetsuit hood, a smile stretched across her face.
You have to experience to understand, she said. I just really missed it.
