A new AI diagnostic tool trained on crowdsourced symptom data can predict whether someone likely has COVID-19 without testing.
The model was trained on data from more than 2.5 million users of the COVID Symptom Study app developed at King’s College London, which anyone can download to report their daily health status.
In a little over a month, a team of physicists and engineers from around the world took a simplified ventilator design from concept all the way through approval by the U.S. Food and Drug Administration. This major milestone marks the ventilator as safe for use in the United States under the FDA’s Emergency Use Authorization, which helps support public health during a crisis.
The Mechanical Ventilator Milano, or MVM, is the brainchild of physicist Cristiano Galbiati. The Gran Sasso Science Institute and Princeton University professor, who normally leads a dark matter experiment in Italy called DarkSide-20k, found himself in lockdown in Milan, a city hit hard by COVID-19. Hearing reports of ventilator shortages and wanting to help, Galbiati reached out to fellow researchers to develop a ventilator with minimal components that could be quickly produced using commonly available parts.
“The sense of crisis was palpable, and I knew the availability of ventilators was critical,” said Galbiati, who obtained his Ph.D from the University of Milan. “We had been doing some complicated projects in physics that required working with gases, and I thought it our duty to find a way to push oxygen into the lungs of patients.”
A new study from researchers at North Carolina State University suggests that a material consisting of a polymer compound embedded with bismuth trioxide particles holds tremendous potential for replacing conventional radiation shielding materials, such as lead.
The bismuth trioxide compound is lightweight, effective at shielding against ionizing radiation such as gamma rays, and can be manufactured quickly—making it a promising material for use in applications such as space exploration, medical imaging and radiation therapy.
“Traditional radiation shielding materials, like lead, are often expensive, heavy and toxic to human health and the environment,” says Ge Yang, an assistant professor of nuclear engineering at NC State and corresponding author of a paper on the work. “This proof-of-concept study shows that a bismuth trioxide compound could serve as effective radiation shielding, while mitigating the drawbacks associated with traditional shielding materials.”

A group of prominent academic scientists that has been advising the U.S. government on security matters since the Cold War is conducting a quick-turnaround, pro bono study of a new threat to national security—the impact of COVID-19 on academic research. And this time it’s personal.
Last month, some 30 members of Jason began to tackle the thorny question of how to reopen university laboratories safely in the midst of the coronavirus pandemic. Nobody is paying for the study, a rare departure for the group, whose work is usually financed by government agencies and often involves classified information. But the study’s leader, Massachusetts Institute of Technology (MIT) physicist Peter Fisher, says several federal agencies have expressed interest in the group’s analysis of the technical challenges facing every university that wants to resume research operations without jeopardizing the health of the faculty, students, and staff who work in those labs.
US and British ships finished naval exercises and sailed out of the Barents Sea on Friday as the Russian navy conducted its own drills in the area.
Stem Cell Neurotherapy sends therapeutic messages, e.g., “your stem cells are transforming into new cells for the lungs, liver, and kidneys” to the DNA inside the nucleus of stem cells. Inside the nucleus, the DNA receives the message and transmits it to the RNA, which translates the message into genetic code.
The genes inside the stem cells transmit the coded message to the proteins, which are converted by the mitochondria into ATP, which provides the energy for the coded message to transform the stem cells into a new set of lung cells, as well as new cells for the kidneys and liver.
These new cells in the lungs, kidneys, and liver will replace the cells that were infected by the COVID-19 virus. This results in the elimination of the coughing, fever, headaches, diarrhea, and breathing problems.
A birthday party was behind a cluster of coronavirus cases in Pasadena, California, according to health officials.
A “large number” of extended family members and friends were at the party, the Pasadena Public Health Department said in <a href=“https://www.cityofpasadena.net/city-manager/news-releases/cluster-of-covid-19-cases-traced-to-birthday-party/ target=“_blank”>a news release, adding the event took place after the city issued a stay-at-home order in March.
One patient at the party was coughing and not wearing a face covering, health officials said, and other party guests were also not covering their face or social distancing…
“The world is currently rightly focused on tackling the global health emergency,” Mark Wright, science director of the U.K. branch of the World Wildlife Fund, told The Guardian. “However, this new research reinforces that, after we are through this extremely difficult time, we will need renewed ambitious action to address the climate and nature crisis.”

The U.S. space agency National Aeronautics Space Administration (NASA), European Space Agency (ESA), and Japan Aerospace Exploration Agency (JAXA) are inviting coders, entrepreneurs, scientists, designers, storytellers, makers, builders, artists, and technologists to participate in a virtual hackathon May 30–31 dedicated to putting open data to work in developing solutions to issues related to the COVID-19 pandemic.
During the global Space Apps COVID-19 Challenge, participants from around the world will create virtual teams that – during a 48-hour period – will use Earth observation data to propose solutions to COVID-19-related challenges ranging from studying the coronavirus that causes COVID-19 and its spread to the impact the disease is having on the Earth system. Registration for this challenge opens in mid-May.
“There’s a tremendous need for our collective ingenuity right now,” said Thomas Zurbuchen, associate administrator for NASA’s Science Mission Directorate. “I can’t imagine a more worthy focus than COVID-19 on which to direct the energy and enthusiasm from around the world with the Space Apps Challenge that always generates such amazing solutions.”
The unique capabilities of NASA and its partner space agencies in the areas of science and technology enable them to lend a hand during this global crisis. Since the start of the global outbreak, Earth science specialists from each agency have been exploring ways to use unique Earth observation data to aid understanding of the interplay of the Earth system – on global to local scales – with aspects of the COVID-19 outbreak, including, potentially, our ability to combat it. The hackathon will also examine the human and economic response to the virus.
