Writing in the journal NanoResearch, a team at the University of Massachusetts Amherst reports this week that they have developed bioelectronic ammonia gas sensors that are among the most sensitive ever made.

The sensor uses electric-charge-conducting protein derived from the bacterium Geobacter to provide biomaterials for electrical devices. More than 30 years ago, senior author and microbiologist Derek Lovley discovered Geobacter in river mud. The microbes grow hair-like protein filaments that work as nanoscale “wires” to transfer charges for their nourishment and to communicate with other bacteria.

First author and doctoral student Alexander Smith, with his advisor Jun Yao and Lovley, say they designed this first sensor to measure ammonia because that gas is important to agriculture, the environment and biomedicine. For example, in humans, ammonia on the breath may signal disease, while in poultry farming, the gas must be closely monitored and controlled for bird health and comfort and to avoid feed imbalances and production losses.

Others are being hit hard by the impact of quarantine — feeling overwhelmed while trying to balance work with childcare, being stuck at home with an abusive partner or parent, or being alone for extended periods of time.

Since it’s Mental Health Awareness Month, here are some tips to help you cope with the crisis:

It turns out that mental illness is normal.

To that point, many people were struggling to keep it together before the crisis. Some had never experienced a mental-health challenge before and are now suffering from anxiety and depression. Some are struggling to adjust to the direct health and economic consequences of the virus — job loss, financial stress, illness and/or the death of a loved one.

Injecting DNA into injured horse tendons and ligaments can cure lameness, new research involving scientists at Kazan Federal University, Moscow State Academy and The University of Nottingham has found.

The gene therapy technology was used in horses that had gone lame due to injury and within two to three weeks the horses were able to walk and trot. Within just two months they were back to full health, galloping and competing.

The study has big implications not just for the veterinary world but the future of human medicine — injuries like these are common in people as well as animals, not just in lameness but in other illnesses and diseases from the legs and arms through to the back and hips.

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 trioxide compound is lightweight, effective at shielding against ionizing radiation such as , and can be manufactured quickly—making it a promising material for use in applications such as , medical imaging and .

“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.”

‘s COVID-19 reporting is supported by the Pulitzer Center.

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.

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.

“If all … went well and it worked well, then I would propose … three months’ time,” she said, when asked how quickly the treatment, which was developed by doctors and researchers at the Abu Dhabi Stem Cell Center, could reach the market.

To date, there are no known vaccines or specific antiviral medicines against Covid-19. U.S. health officials say developing a vaccine will take at least 12 to 18 months.

The UAE has 14,163 cases and 126 deaths due to the coronavirus, based on data from Johns Hopkins University.

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…
