The University of California, Davis is giving students $ 75 to use for “stays” to encourage them to avoid non-essential travel during spring breakBy The Associated PressMarch 10, 2021, 11:08 pm • 2 min readShare on FacebookShare on Twitter – The University of California at Davis is offering students $ 75 to use for “stays” to encourage them to avoid non-essential travel during spring break. Students who choose to stay home during the March 22-26 vacation will receive the money in the form of gift cards. The response from students has been “impressive,” the university said in a statement. “The idea behind this was to provide a positive incentive for students to follow public health advice,” Sheri Atkinson, associate vice chancellor for student affairs, told the Los Angeles Times. About 50% of students live on campus or in the Davis area, she said. They must commit to staying in town for their week-long break and taking a COVID-19 test. The university initially planned to award 750 such scholarships, but due to student interest, it raised the cap to 2,000. The planned $ 150,000 program will be paid for by philanthropy and other university funds – not student fees or tuition, Atkinson said. campus.Texas A&M University has opted for a three-day weekend instead of a full week. The University of Alabama and the University of Wisconsin-Madison have also eliminated spring break, but are offering students a day off later in the semester. The University of Mississippi has also canceled spring break, but will end the semester a week early. .
World renowned chef Thomas Keller once said, “Respecting food is respecting life, for who we are and what we do.” But, at the moment 40% of the country’s food is not eaten – over 66 million tons a year – and the results are widespread, from starvation to taxes on the environment and the economy.
Growing, processing, transporting, and disposing of uneaten food in the United States is expensive. Nationally, this translates to an estimated annual price of $ 218 billion, at the cost of a house of four an average of $ 1,800 a year. Apart from that, needy wasted food more than 20% of national landfills, where it produces methane, a greenhouse gas up to 86 times stronger than carbon dioxide.
Now, a team from the University of California, Riverside (UCR), has found a way to keep unused food out of landfills and use it for more beneficial uses.
What the researchers found in their studies Citrus plants, published in the journal Frontier in Sustainable Food Systems, show that fermented food waste can actually increase bacteria which – in addition to increasing plant growth – can make plants more resistant to pathogens and reduce carbon emissions from agriculture.
“The beneficial microbes increase dramatically when we add fermented food waste to plant growth systems,” says UCR microbiologist Deborah Pagliaccia, who led the research. “When there are sufficient numbers of these good bacteria, they produce antimicrobial compounds and metabolites that help plants grow better and faster.”
To help combat some of the environmental damage caused by food waste, the UCR research team set out to find alternative uses other than bins. For their research, they examined the byproducts of two types of waste available in Southern California: beer collision – a byproduct of beer production – and mixed food waste dumped by grocery stores.
After the waste is fermented, it is added to the citrus irrigation system in greenhouses. Within a day, the average population of beneficial bacteria has doubled to two to three times greater than that of untreated plants. This trend continues whenever researchers add treatments.
The end result is the same as optimal production for crops as well as reduced costs for farmers. “If the waste byproducts can increase the carbon to nitrogen ratio in the plant, we can leverage this information to optimize the production system,” says Pagliaccia.
The study suggests the use of the food waste byproducts under study could also complement the use of synthetic chemical additives by manufacturers – in some cases eliminating the use of those additives altogether. Plants will, in turn, become cheaper.
“There is an urgent need to develop new agricultural practices,” said UCR plant pathologist and study co-author Georgios Vidalakis. “California oranges, in particular, face historical challenges such as Huanglongbing’s bacterial disease and limited water availability.”
Pagliaccia also emphasized that new methods must be developed. “We have to transition from a linear ‘take-make-consume-waste’ economy to a circular economy where we use something and then find new purposes for it. This process is critical to protecting our planet from depletion of natural resources and the threat of greenhouse gases. That’s the story of this project. “
Researchers at the University of California, Berkeley have created a new device that combines wearable biosensors with artificial intelligence (AI) software that can recognize gestures that a person intends to make based on patterns of electrical signals in the forearm. According to research published on the UC Berkeley website, the device paves the way for “better repair control and seamless interaction” with electronic devices. Essentially, this means that the technology can be used to perform complex robotic medical procedures or other daily tasks, such as typing or even games, without actually having to do it.
The researchers claim that the team successfully taught the algorithm to recognize 21 individual gestures, including thumbs up, fists, flat hands, raising individual fingers and counting numbers. Researchers say the device is not ready for commercial use, although it can be used almost with minor adjustments. The research paper added that there are other ways to improve human-computer interaction through cameras and computer vision, but this new device can store all data locally while ensuring personal privacy. Engineers claim that this not only speeds up the calculation time, but also ensures that personal biological data remains private.

“When Amazon or Apple creates an algorithm, they run a bunch of software in the cloud to create a model, and then download the model to your device,” Professor of Electrical Engineering at the University of California, Berkeley and senior author of the book. Rabe (Jan Rabaey) said. paper. “In our method, we implemented a process in which learning is done on the device itself. This is very fast. You only need to do it once to start working. However, if you do it multiple times, it can change Better. So this is continuous learning, and this is the way humans learn.”
The team worked with Ana Arias, a professor of electrical engineering at the University of California, Berkeley, to create a gesture recognition system. The team jointly designed a flexible armband that can read electrical signals at 64 different points on the forearm. The electrical signals are then fed to an electronic chip, which is programmed with an AI algorithm, which can associate these signal patterns in the forearm with specific gestures. In addition, the device uses an advanced AI called “super-dimensional calculation algorithm” to update itself with new information. “In gesture recognition, your signal will change over time, which will affect the performance of the model. We can greatly improve the classification accuracy by updating the model on the device,” said the person who helped design the device as a doctoral student.
Finally, the researchers claim that the uniqueness of the device is that it integrates biosensing, signal processing and interpretation, and AI into a relatively small, flexible, and low-power budget system.
“I wanted to say that I am quite tense,” – said General hospital San Francisco ER doctor, Rob Rodriguez, who spoke to ABC7 on Tuesday evening, after landing in Brownsville, Texas.
Dr. Rodriguez from Brownsville and there is a volunteer in the hospital where they are undergoing a major splash.
“A good friend of mine is in intensive care at a local hospital.”
Stress is something that Rodriguez became very familiar. He is the lead author of the first known study on physician stress levels during a pandemic.
More than 400 emergency physicians surveyed in California, Louisiana and new Jersey, and Rodriguez said that they all have something in common.
“We’ve noticed a surge in the General level of anxiety”.
The study shows, emotional exhaustion and burnout among doctors is significantly improved when the pandemic began, and that there are differences between how men and women were injured. Female doctors reported slightly higher stress levels at work and at home.
“Women are more likely to have a stewardship role, whether with children or with a relative,” said Mary Crow, head of emergency medicine in California. “They are also more likely to provide more hours of care than their male counterparts. It’s very, very tense”.
Dr. Raven took part in the study in March and April, when much less was known about transmission of the virus.
Most doctors surveyed reported changes in behaviour in relation to family and friends, especially by attachment.
“There were a couple times when I had minor symptoms and was tested and was negative, but you have to be a lot more careful, especially as a doctor, where you could really bring it home. You can’t just mindlessly hug your child as normal as possible,” said Raven.
Both Rodriguez and Raven say increased supplies of PPE has reduced doctor stress levels. They both say that the anxiety can be even more reduced if rapid testing were more widespread and if everyone had to wear the mask more seriously.
“We all need to take responsibility and wear masks,” said Rodriguez.
Rodriguez said he will continue to study the stress levels through the pandemic, to address the various stressors that occur as the occurrence of various problems.
