TOKYO (Reuters) — Men wearing traditional loin clothes and women dressed in white robes clapped and chanted before going into an ice water bath during a Shinto ritual at a Tokyo shrine on Sunday to purify the soul and pray for the end of the COVID-19 pandemic.

Only a dozen people took part in the annual event at Teppou-zu Inari Shrine, scaled down this year due to the health crisis, compared to over a hundred in early 2020. Spectators were not allowed at the event.

After doing warming-up exercises and chanting under a clear sky with outside temperatures at 5.1 degree Celsius (41.18 Fahrenheit), the nine male and three female participants went into a bath filled with cold water and large ice blocks. “I prayed that the coronavirus comes to an end as soon as possible,” said 65-year-old participant Shinji Ooi, who heads the Shrine’s ‘Yayoikai’ parishioner group, after the ritual.

A scalpel-free alternative to brain surgery has the potential to benefit people with Parkinson’s disease symptoms that are much more severe on one side of the body, new research suggests.

More testing is needed, but the approach, which uses a technology called focused ultrasound, could offer a new option for patients whose symptoms are poorly controlled by medications and those who cannot or do not wish to undergo traditional brain surgery.

“This small brain region, the subthalamic nucleus, had a very strong and potent effect on parkinsonian symptoms when we targeted it with precise, focused ultrasound energy,” said researcher Jeff Elias, MD, a neurosurgeon at UVA Health and a pioneer in the field of focused ultrasound. “The key for the ultimate adoption of this new procedure will be further refinements of the technology to ensure reliability and safety.”

At the more advanced end of things, genetic modifications and advanced medical procedures might be available in the future that can restore muscle tissue, bone density, and organ health. If such treatments are available down the road, periodic visits to the doctor could allow Loonies to live happy and healthy lives in lower gravity.

In so many ways, a permanent human presence on the Moon could open the door to the entire Solar System. With the ability to refuel and resupply missions from a lunar site, space agencies could shave billions off the cost of deep-space missions. It would also facilitate missions to Mars, Venus, the Asteroid Belt, and beyond.

Lawrence Livermore National Laboratory (LLNL) researchers have discovered that carbon nanotube membrane pores could enable ultra-rapid dialysis processes that would greatly reduce treatment time for hemodialysis patients.

The ability to separate molecular constituents in complex solutions is crucial to many biological and man-made processes. One way is via the application of a concentration gradient across a porous membrane. This drives ions or molecules smaller than the pore diameters from one side of the membrane to the other while blocking anything that is too large to fit through the pores.

In nature, biological membranes such as those in the kidney or liver can perform complex filtrations while still maintaining high throughput. Synthetic membranes, however, often struggle with a well-known trade-off between selectivity and permeability. The same material properties that dictate what can and cannot pass through the membrane inevitably reduce the rate at which filtration can occur.

Every year, over a million people develop health care-acquired infections during their hospital stays. And around 100000 of them die from those complications.

But researchers at the University of Georgia are determined to change that, and their new study shows a promising tool for preventing infections before they happen.

Brown fat is that magical tissue that you would want more of. Unlike white fat, which stores calories, brown fat burns energy and scientists hope it may hold the key to new obesity treatments. But it has long been unclear whether people with ample brown fat truly enjoy better health. For one thing, it has been hard to even identify such individuals since brown fat is hidden deep inside the body.

Now, a new study in Nature Medicine offers strong evidence: among over 52000 participants, those who had detectable brown fat were less likely than their peers to suffer cardiac and metabolic conditions ranging from type 2 diabetes to coronary artery disease, which is the leading cause of death in the United States.

The study, by far the largest of its kind in humans, confirms and expands the health benefits of brown fat suggested by previous studies. “For the first time, it reveals a link to lower risk of certain conditions,” says Paul Cohen, the Albert Resnick, M.D., Assistant Professor and senior attending physician at The Rockefeller University Hospital. “These findings make us more confident about the potential of targeting brown fat for therapeutic benefit.”

The enormous impact of the recent COVID-19 pandemic, together with other diseases or chronic health risks, has significantly prompted the development and application of bioelectronics and medical devices for real-time monitoring and diagnosing health status. Among all these devices, smart contact lenses attract extensive interests due to their capability of directly monitoring physiological and ambient information. Smart contact lenses equipped with high sensitivity sensors would open the possibility of a non-invasive method to continuously detect biomarkers in tears. They could also be equipped with application-specific integrated circuit chips to further enrich their functionality to obtain, process and transmit physiological properties, manage illnesses and health risks, and finally promote health and wellbeing. Despite significant efforts, previous demonstrations still need multistep integration processes with limited detection sensitivity and mechanical biocompatibility.

Recently, researchers from the University of Surrey, National Physical Laboratory (NPL), Harvard University, University of Science and Technology of China, Zhejiang University Ningbo Research Institute, etc. have developed a multifunctional ultrathin contact lens sensor system. The sensor systems contain a photodetector for receiving optical information, imaging and vision assistance, a temperature sensor for diagnosing potential corneal disease, and a glucose sensor for monitoring glucose level directly from the tear fluid.

Dr. Yunlong Zhao, Lecturer in Energy Storage and Bioelectronics at the Advanced Technology Institute (ATI), University of Surrey and Senior Research Scientist at the UK National Physical Laboratory (NPL), who led this research stated, “These results provide not only a novel and easy-to-make method for manufacturing advanced smart contact lenses but also a novel insight of designing other multifunctional electronics for Internet of Things, human machine interface, etc.” Dr. Zhao added, “our ultrathin transistors-based serpentine mesh sensor system and fabrication strategy allow for further incorporation of other functional components, such as electrode array for electrophysiology, antennas for wireless communication, and the power modules, e.g. thin-film batteries and enzymatic biofuel cell for future in vivo exploration and practical application. Our research team at ATI, University of Surrey and NPL are currently working on these fields.”

SANTIAGO (Reuters) — The coronavirus has landed in Antarctica, the last continent previously free from COVID-19, Chile’s military said this week, as health and army officials scrambled to clear out and quarantine staff from a remote research station surrounded by ocean and icebergs.

Unmanned Aerial Vehicles (UAV), commonly referred to as drones, may prove to be a valuable tool in the battle against pandemics like COVID-19. Researchers at the University of Calgary, the Southern Alberta Institute of Technology (SAIT), Alberta Health Services (AHS) and Alberta Precision Laboratories (APL) are partnering with the Stoney Nakoda Nations (SNN) to deliver medical equipment and test kits for COVID-19 to remote areas, and to connect these communities to laboratories more quickly using these remotely piloted aircraft.

Access for all

“We know that testing for COVID-19 is one of our most effective tools against its spread. Many remote communities in Canada do not have easy access to testing centres and medical supplies to support rapid testing and containment. Drones can help us respond to that need,” says Dr. John Conly, MD, medical director of the W21C Research and Innovation Centre at the Cumming School of Medicine (CSM) and co-principal investigator on the project.
