The world's largest solar power project begins running in UAE
Will the small petrol state soon be solar powered?

- The United Arab Emirates is on a solar kick — it has just opened the world's largest solar farm.
- This is only one of several huge power plants they've opened recently.
- While the country is still heavily dependent on oil, the new solar plants may change things.
You might have heard that the United Arab Emirates is building a concentrated solar power plant that will keep the lights on after the sun goes down. While that might be impressive enough by itself, it isn't the only solar plant they have. In fact, they just opened up the world's largest conventional solar plant this week.
Let there be light from sunlight!
The world’s largest single solar plant, Noor Abu Dhabi, with a production capacity of nearly 1,177 MW commences co… https://t.co/3HK90vTp2w— المكتب الإعلامي لحكومة أبوظبي (@المكتب الإعلامي لحكومة أبوظبي)1561796620.0
Noor Abu Dhabi is the world's new largest individual solar power plant. Built at the cost of almost $900M, the plant contains 3.2 million solar panels. It will produce 1.17 gigawatts of power; enough to supply the needs of 90,000 people and reduce their yearly carbon emissions by 1,000,000 metric tons. This is the equivalent of taking 200,000 cars off the roads.
However, it will not make quite enough electricity to make a DeLorean go back in time.
How do other operations compare?
While Noor Abu Dhabi is the world's largest solar site, others come close. Shakti Sthala, in India, produces 2 gigawatts of power and Longyangxia Dam Solar Park in China has four million solar panels producing 850 megawatts. For comparison, the largest facility in the United States is Solar Star, which produces 569 megawatts of power.
The UAE better watch out though, because Saudi Arabia is working on a solar farm outside of Mecca that will produce 2.6 gigawatts of power when it's done.
Does this mean the UAE is going green?

Kinda sorta.
Last year they opened the Mohammed bin Rashid Al Maktoum Solar Park and has been investing billions upon billions of dollars into solar power for a while now. The plan, according to the vice president of the UAE, Sheikh Mohammed bin Rashid al-Maktoum, is to "balance our economic needs with our environmental goals."
According to the head of the Emirates Water and Electric Company, Mohammad Hassan Al Suwaidi, this solar plant is part of an ambitious program of cleaning up their energy sources:
"The completion of the project marks a significant milestone in the UAE's Energy Strategy 2050, launched in 2017, to increase the contribution of clean energy in the total energy mix to 50 percent by 2050 while reducing the carbon footprint of power generation by 70 percent."
However, they are still very reliant on fossil fuels and take steps to keep the price of oil where they want it so their economy doesn't collapse.
This new solar farm is a step in the right direction, but it is still only a step.
As the nations of the world become more aware of the problems fossil fuels can cause they are increasingly turn to renewables. While the UAE isn't about to stop selling oil anytime soon, it has made a bold move toward a greener future with this solar plant. Will it one day be known for solar power rather than petroleum? Only time will tell.

How New York's largest hospital system is predicting COVID-19 spikes
Northwell Health is using insights from website traffic to forecast COVID-19 hospitalizations two weeks in the future.
- The machine-learning algorithm works by analyzing the online behavior of visitors to the Northwell Health website and comparing that data to future COVID-19 hospitalizations.
- The tool, which uses anonymized data, has so far predicted hospitalizations with an accuracy rate of 80 percent.
- Machine-learning tools are helping health-care professionals worldwide better constrain and treat COVID-19.
The value of forecasting

<p>One unique benefit of forecasting COVID-19 hospitalizations is that it allows health systems to better prepare, manage and allocate resources. For example, if the tool forecasted a surge in COVID-19 hospitalizations in two weeks, Northwell Health could begin:</p><ul><li>Making space for an influx of patients</li><li>Moving personal protective equipment to where it's most needed</li><li>Strategically allocating staff during the predicted surge</li><li>Increasing the number of tests offered to asymptomatic patients</li></ul><p>The health-care field is increasingly using machine learning. It's already helping doctors develop <a href="https://care.diabetesjournals.org/content/early/2020/06/09/dc19-1870" target="_blank">personalized care plans for diabetes patients</a>, improving cancer screening techniques, and enabling mental health professionals to better predict which patients are at <a href="https://healthitanalytics.com/news/ehr-data-fuels-accurate-predictive-analytics-for-suicide-risk" target="_blank" rel="noopener noreferrer">elevated risk of suicide</a>, to name a few applications.</p><p>Health systems around the world have already begun exploring how <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7315944/" target="_blank" rel="noopener noreferrer">machine learning can help battle the pandemic</a>, including better COVID-19 screening, diagnosis, contact tracing, and drug and vaccine development.</p><p>Cruzen said these kinds of tools represent a shift in how health systems can tackle a wide variety of problems.</p><p>"Health care has always used the past to predict the future, but not in this mathematical way," Cruzen said. "I think [Northwell Health's new predictive tool] really is a great first example of how we should be attacking a lot of things as we go forward."</p>Making machine-learning tools openly accessible
<p>Northwell Health has made its predictive tool <a href="https://github.com/northwell-health/covid-web-data-predictor" target="_blank">available for free</a> to any health system that wishes to utilize it.</p><p>"COVID is everybody's problem, and I think developing tools that can be used to help others is sort of why people go into health care," Dr. Cruzen said. "It was really consistent with our mission."</p><p>Open collaboration is something the world's governments and health systems should be striving for during the pandemic, said Michael Dowling, Northwell Health's president and CEO.</p><p>"Whenever you develop anything and somebody else gets it, they improve it and they continue to make it better," Dowling said. "As a country, we lack data. I believe very, very strongly that we should have been and should be now working with other countries, including China, including the European Union, including England and others to figure out how to develop a health surveillance system so you can anticipate way in advance when these things are going to occur."</p><p>In all, Northwell Health has treated more than 112,000 COVID patients. During the pandemic, Dowling said he's seen an outpouring of goodwill, collaboration, and sacrifice from the community and the tens of thousands of staff who work across Northwell.</p><p>"COVID has changed our perspective on everything—and not just those of us in health care, because it has disrupted everybody's life," Dowling said. "It has demonstrated the value of community, how we help one another."</p>3,000-pound Triceratops skull unearthed in South Dakota
"You dream about these kinds of moments when you're a kid," said lead paleontologist David Schmidt.
Excavation of a triceratops skull in South Dakota.
- The triceratops skull was first discovered in 2019, but was excavated over the summer of 2020.
- It was discovered in the South Dakota Badlands, an area where the Triceratops roamed some 66 million years ago.
- Studying dinosaurs helps scientists better understand the evolution of all life on Earth.

<p style="margin-left: 20px;">"We had to be really careful," Schmidt told St. Louis Public Radio. "We couldn't disturb anything at all, because at that point, it was under law enforcement investigation. They were telling us, 'Don't even make footprints,' and I was thinking, 'How are we supposed to do that?'"</p><p>Another difficulty was the mammoth size of the skull: about 7 feet long and more than 3,000 pounds. (For context, the largest triceratops skull ever unearthed was about <a href="https://www.tandfonline.com/doi/abs/10.1080/02724634.2010.483632" target="_blank">8.2 feet long</a>.) The skull of Schmidt's dinosaur was likely a <em>Triceratops prorsus, </em>one of two species of triceratops that roamed what's now North America about 66 million years ago.</p>Credit: David Schmidt / Westminster College
<p>The triceratops was an herbivore, but it was also a favorite meal of the T<em>yrannosaurus rex</em>. That probably explains why the Dakotas contain many scattered triceratops bone fragments, and, less commonly, complete bones and skulls. In summer 2019, for example, a separate team on a dig in North Dakota made <a href="https://www.nytimes.com/2019/07/26/science/triceratops-skull-65-million-years-old.html" target="_blank">headlines</a> after unearthing a complete triceratops skull that measured five feet in length.</p><p>Michael Kjelland, a biology professor who participated in that excavation, said digging up the dinosaur was like completing a "multi-piece, 3-D jigsaw puzzle" that required "engineering that rivaled SpaceX," he jokingly told the <a href="https://www.nytimes.com/2019/07/26/science/triceratops-skull-65-million-years-old.html" target="_blank">New York Times</a>.</p>Morrison Formation in Colorado
