Energy efficient light-emitting diodes (LEDs) have been used in our everyday life for many decades. But the quest for better LEDs, offering both lower costs and brighter colors, has recently drawn scientists to a material called perovskite. A recent joint-research project co-led by the scientist from City University of Hong Kong (CityU) has now developed a 2-D perovskite material for the most efficient LEDs.

From household lighting to mobile phone displays, from pinpoint lighting needed for endoscopy procedures, to light source to grow vegetables in Space, LEDs are everywhere. Yet current high-quality LEDs still need to be processed at high temperatures and using elaborated deposition technologies—which makes their production cost expensive.

Scientists have recently realized that —semiconductor materials with the same structure as calcium titanate mineral, but with another elemental composition—are extremely promising candidate for next generation LEDs. These perovskites can be processed into LEDs from solution at room temperature, thus largely reducing their production cost. Yet the electro-luminescence performance of perovskites in LEDs still has a room for improvements.

While these tools will enable our society to reopen (and stay open) by improving detection of the virus, CRISPR will also have an important effect on the way we treat other diseases. In 2021, we will see increased use of CRISPR-Cas enzymes to underpin a new generation of cost-effective, individualised therapies. With CRISPR enzymes, we can cut DNA at precise locations, using specifically designed proteins, and insert or delete pieces of DNA to correct mutations.

As we deepen our understanding of the human genome and genetic disorders, patients with previously intractable diseases, such as sickle-cell disease and cancer, will benefit more widely from CRISPR-based therapies that are rapidly moving from the lab to the clinic. In 2019, sickle-cell patient Victoria Gray, for example, became one of the first patients in the world to receive CRISPR therapy for her genetic disease. She has already seen significant improvements to her health, including reduced pain and less frequent need for blood transfusions.

CRISPR will also allow us to act more boldly in the face of other important, interconnected issues such as food security, environmental sustainability and social inequality. The technology will help us grow more nutritious and robust crops, establish “gene drives” to control the spread of other infectious diseases such as Zika, and develop cleaner energy sources such as algae-based biofuels.

Advocates contend central bank digital currencies can make cross-border transactions easier, promote financial inclusion and provide payment system stability. There are also privacy and surveillance risks with government-issued digital currencies. And in times of economic uncertainty, people may be more likely to pull their funds from commercial banks, accelerating a bank run.

Intense interest in cryptocurrencies and the Covid-19 pandemic have sparked debate among central banks on whether they should issue digital currencies of their own.

China has been in the lead in developing its own digital currency. It’s been working on the initiative since 2014. Chinese central bank officials have already conducted massive trials in major cities including Shenzhen, Chengdu and Hangzhou.

“China’s experiment is very large scale,” said J. Christopher Giancarlo, former chairman of the U.S. Commodity Futures Trading Commission. “When the world arrives in Beijing next winter for the Winter Olympics, they are going to be using the new digital renminbi to shop and to stay in hotels and to buy meals in restaurants. The world is going to see a functioning [central bank digital currency] very soon, within the coming year.”

Have you ever heard of “Allostatic Load” and “Operator Syndrome?”

I stumbled across the work of Christopher Frueh while doing some research on physiological, psychological and hormonal stress mitigation. Frueh, along with his team of researchers, psychologists and former SOF operators, has been exploring the human mind, defining PTSD and outlining Special Operator’s Syndrome. This is one of the only programs in the country specifically designed to help those suffering from this condition.

“Allostatic load” is the cost on your body of chronic stress and physical demands of a career with the military special forces, according to Science Direct. The military recipe for “burning the candle at both ends” includes high intensity physical fitness training, the high stress of operations and being away from home, the trauma of witnessing death, war or injury. Add in the inability to sleep or eat well, and the operator limits the two main recovery responses, which leads to chronic stress. This adds up to Allostatic Overload.

SFU-led research team uncovers how fossil dragonfly relatives have been misclassified due to their striking similarity.

For more than 150 years, scientists have been incorrectly classifying a group of fossil insects as damselflies, the familiar cousins of dragonflies that flit around wetlands eating mosquitoes. While they are strikingly similar, these fossils have oddly shaped heads, which researchers have always attributed to distortion resulting from the fossilization process.

Now, however, a team of researchers led by Simon Fraser University (SFU) paleontologist Bruce Archibald has discovered they aren’t damselflies at all, but represent a major new insect group closely related to them.

“” We’re looking at Flippy as a tool that helps us increase speed of service and frees team members up to focus more on other areas we want to concentrate on, whether that’s order accuracy or how we’re handling delivery partner drivers and getting them what they need when they come through the door.”, said White Castle’s Vice President, Jamie Richardson.”

Flippy is the world’s first autonomous robotic kitchen assistant that can learn from its surroundings and acquire new skills over time.

Mr. — Chairman, Joseph P. Kennedy Enterprises — Our discussion starts out on U.S. food insecurity, but journeys into the topics of aging, as well as regeneration research at University of Chicago’s MBL.

A “food desert” is an area that has limited access to affordable and nutritious food, and the designation considers both the type and quality of food available, as well as the accessibility of the food through the size and proximity of the food stores.

In 2010, the United States Department of Agriculture reported that 23.5 million people in the U.S. lived in food deserts, meaning that they live more than one mile from a supermarket in urban or suburban areas and more than 10 miles from a supermarket in rural areas.

Food deserts tend to be inhabited by lower-income residents with reduced mobility, making them a less attractive market for large supermarket chains and available foods are often of the highly processed type, high in sugars and fats, which are known contributors to the proliferation of obesity and other chronic diseases. It’s estimated that the contribution of food deserts to healthcare costs in the U.S. is over $70 billion annually.

Top Box Foods is a non-profit, community-based, social business, with an innovative model of getting healthy and affordable grocery boxes to food-insecure neighborhoods, creating year round access to fresh fruits, vegetables, and proteins, in communities in Chicago, and Lake County, IL, as well as in New Orleans, LA.

Mr. Christopher Kennedy, along with his wife Sheila Kennedy, is a co-founder of Top Box Foods.

In addition to Top Box Foods, Mr. Kennedy is Chairman of the Board of Trustees of Joseph P. Kennedy Enterprises, Inc., treasurer of the Joseph P. Kennedy Jr. Foundation, serves on the public boards of Interface, Inc., and Knoll Inc., and is a trustee for the Marine Biological Laboratory at University of Chicago.

Mr. Kennedy earned his BA from Boston College and his MBA from the Kellogg Graduate School of Management at Northwestern University, where he serves on their Global Advisory Board.

Ultimately, Cyrille Przybyla, an aquaculture researcher at the French Research Institute for Exploitation of the Sea who led the research, dreams of designing a lunar fish farm that uses water already on the moon to help feed residents of the future Moon Village set to be established by the European Space Agency (ESA). The Lunar Hatch project is just one of around 300 ideas currently under evaluation by the ESA, and may or may not be selected for the final mission. Przybyla’… See More.
