A team of researchers from the Max Planck Institute of Molecular Plant Physiology, the University of Naples Federico II, the Weizmann Institute of Science and the Porter School of the Environment and Earth Sciences has found that making food from air would be far more efficient than growing crops. In their paper published in Proceedings of the National Academy of Sciences, the group describes their analysis and comparison of the efficiency of growing crops (soybeans) and using a food-from-air technique.

For several years, researchers around the world have been looking into the idea of growing “ from air,” combining a renewable fuel resource with carbon from the air to create food for a type of bacteria that create edible protein. One such project is Solar Foods in Finland, where researchers have the goal of building a demonstration plant by 2023. In this new effort, the researchers sought to compare the efficiency of growing a staple crop, soybeans, with growing food from air.

To make their comparisons, the researchers used a food-from-air system that uses solar energy panels to make electricity, which is combined with from the air to produce food for microbes grown in a bioreactor. The protein the microbes produce is then treated to remove and then dried to produce a powder suitable for consumption by humans and animals.

While chlorine and ultraviolet light are the standard means of disinfecting water, ozone is equally effective in killing germs. To date, ozone has only been used as an oxidation agent for treating water in large plants. Now, however, a project consortium from Schleswig-Holstein is developing a miniaturized ozone generator for use in smaller applications such as water dispensers or small domestic appliances. The Fraunhofer Institute for Silicon Technology ISIT has provided the sensor chip and electrode substrates for the electrolysis cell.

Compared to conventional means of disinfection such as chlorine or ultraviolet, ozone dissolved in water has a number of advantages: it is environmentally friendly, remains active beyond its immediate place of origin, has only a short retention time in water and is subsequently tasteless. Due to its high oxidation potential, ozone is very effective at combating germs. It breaks down the cell membrane of common pathogens. In Germany, ozone is chiefly used to disinfect swimming pools and drinking water and to purify wastewater. Yet it is rarely used to disinfect water in domestic appliances such as ice machines and beverage dispensers or in other fixtures such as shower-toilets. MIKROOZON, a project funded by the State of Schleswig-Holstein and the EU, aims to change this.

As COVID-19 continues to ravage global populations, the world is singularly focused on finding ways to battle the novel coronavirus. That includes the UC Santa Barbara’s Solid State Lighting & Energy Electronics Center (SSLEEC) and member companies. Researchers there are developing ultraviolet LEDs that have the ability to decontaminate surfaces — and potentially air and water — that have come in contact with the SARS-CoV-2 virus.

“One major application is in medical situations — the disinfection of personal protective equipment, surfaces, floors, within the HVAC systems, et cetera,” said materials doctoral researcher Christian Zollner, whose work centers on advancing deep ultraviolet light LED technology for sanitation and purification purposes. He added that a small market already exists for UV-C disinfection products in medical contexts.

Indeed, much attention of late has turned to the power of ultraviolet light to inactivate the novel coronavirus. As a technology, ultraviolet light disinfection has been around for a while. And while practical, large-scale efficacy against the spread of SARS-CoV-2 has yet to be shown. UV light shows a lot of promise: SSLEEC member company Seoul Semiconductor in early April reported a “99.9% sterilization of coronavirus (COVID-19) in 30 seconds” with their UV LED products. Their technology currently is being adopted for automotive use, in UV LED lamps that sterilize the interior of unoccupied vehicles.

The U.S. is facing an unprecedented shortage of obstetricians and gynecologists (OB/GYNs). According to the American College of Obstetricians and Gynecologists, around half of the nation’s counties don’t have access to even a single OB/GYN, which means more than 10 million women are in need of OB/GYNs for primary care. Alarmingly, there are now 8000 fewer women’s health specialists than needed, and that number is predicted rise to 22000 by mid-century.

As the nation’s largest group of Maternal-Fetal Medicine (MFM) and OB/GYN Hospitalist providers, Obstetrix Medical Group is uniquely addressing this critical issue. With multiple diverse TeleMFM programs around the country, Obstetrix provides a key solution for hospitals and community OB/GYN physicians that improves access to specialty care for women with high-risk pregnancies.

Mednax clinicians have long relied on the benefits of telehealth to complement traditional in-person care. MFM providers specifically have utilized various forms of telehealth since the late 1980s. Today, virtual care continues to play an essential role in bridging distance gaps and bringing the highest quality care to patients in need, no matter their location. Through the use Vsee, one of Mednax’s primary telehealth platform vendors, as well as others, clinicians across the country are finding a silver lining during the COVID-19 pandemic. Though helpful in any region, in the rural areas of the Mountain West, it has become even more of a blessing. We spoke with Oliver (Bill) Jones, M.D., about how telehealth integrated into their practice and how it has positively impacted their high-risk patients.

COVID-19 was linked to brain tissue loss in a U.K. brain imaging study, according to early findings published June 15 in the preprint server medRxiv.

The study involved 782 participants, with researchers comparing brain scans from before and after COVID-19 infection. Researchers pulled data from the U.K. Biobank, which scanned more than 40000 participants before the pandemic hit the region, allowing them to invite participants back for a second imaging visit.

Findings showed tissue loss in certain parts of the brain.

Google has invested heavily in healthcare. I think in the end, they will be the ultimate profile provider for users. Just connect your electronic health record with your personal profile combined with Fitbit wearable technologies.

Google has made moves to expand its presence in the healthcare sector during the last 12 months, including multiple partnerships with health systems, several new product launches and efforts to facilitate the country’s COVID-19 vaccine rollout.

Below is a timeline of Google’s key healthcare moves reported by Becker’s Hospital Review since June 2020.

June 18, 2020: Google sister company Verily developed a program to help employees and students safely return to offices and shared spaces while monitoring for COVID-19. The program, dubbed Healthy at Work, is powered by Verily’s software and COVID-19 testing infrastructure.

An aging/longevity link, (not sure how novel)

As life expectancies around the world increase, so are the number of people who will experience age-related cognitive decline. The amount of oxygen in the blood declines with age. Aging in the brain might be naturally held at bay by adenosine receptor A2B (ADORA2B), a protein on the membrane of red blood cells which is known to help release oxygen from the blood cells so it can be used by the body.

Aging in the brain is naturally reduced by ADORA2B, which helps get oxygen to the brain when needed. Further testing will be needed to determine whether ADORA2B levels naturally decline with age and whether treatment with drugs that activate ADORA2B can reduce cognitive decline in normal mice.

The Environmental Protection Agency (EPA) will reconsider decisions underlying a rule governing emissions of a chemical that it has deemed carcinogenic following a request from an industry group.

The agency told stakeholders in letters dated last week that it would reconsider its risk information for ethylene oxide, a chemical the EPA currently says is carcinogenic if it is inhaled.

The EPA also said it would reconsider its prior decision not to use a much lower risk finding from the state of Texas as an alternative risk value.

The scientists found “biotin paint” on a protein named RSK1, which is part of a complex that keeps a nearby group of proteins, called RAS proteins, dormant. The scientists were surprised to discover that when they inactivated mutant KRAS, the nearby RSK1 complex stopped working as well. This allowed the RAS proteins to activate and take over the work of the missing mutant KRAS.

Cancer cells can become resistant to treatments through adaptation, making them notoriously tricky to defeat and highly lethal. Cold Spring Harbor Laboratory (CSHL) Cancer Center Director David Tuveson and his team investigated the basis of “adaptive resistance” common to pancreatic cancer. They discovered one of the backups to which these cells switch when confronted with cancer-killing drugs.

KRAS is a gene that drives . Most pancreatic cancers have a mutation in the KRAS protein, causing uncontrolled growth. But, drugs that shut off mutant KRAS do not stop the proliferation. The find a way to bypass the blockage and keep on dividing. Derek Cheng, the lead author of the study and a former Medical Scientist Training Program student in the Tuveson lab, compares this process to backup engines on a ship. He says, “You take away your , you’re kind of on some backup engines. But it’s getting by on those. The ship isn’t sinking yet. It’s still moving at a slower pace. Ultimately what we want to do is sink the ship.”

Tuveson and his team wanted to figure out the “backup engines” in these cells. They used a technique called biotin proximity labeling to identify what other proteins interacted with mutant KRAS. Cheng says, “I basically attach a spray can to my favorite protein, or rather least favorite protein, in this case. And so it attaches biotin, basically spraying biotin ‘paint’ to nearby proteins, and we’re able to analyze it to figure out what proteins were labeled.”
