Posted by in categories: biotech/medical, employment, finance, health

Serious psychological distress among U.S. adults remained fairly steady between April and July 2020, according to a research letter published online Nov. 23 in the Journal of the American Medical Association.

Emma E. McGinty, Ph.D., from the Johns Hopkins Bloomberg School of Public Health in Baltimore, and colleagues conducted two waves of the Johns Hopkins COVID-19 Civic Life and Public Health Survey (April 7 to April 13, 2020, and July 7 to July 22, 2020). Changes in during the COVID-19 pandemic was evaluated among 1,337 U.S. adults.

The researchers found that 13 percent of respondents reported serious in July 2020 versus 14.2 percent in April 2020, with 72 percent of adults reporting serious distress in both waves. The prevalence of serious distress was highest among adults aged 18 to 29 years (25.4 percent in April versus 26.5 percent in July), those with income less than $35,000 (20.2 percent in April versus 21.2 percent in July), and Hispanic individuals (17.9 percent in April versus 19.2 percent in July) at both time points. Among those with serious distress, the most common stressors were concerns about contracting COVID-19 (65.9 percent) and pandemic effects on employment (65.1 percent) and finances (60.6 percent). Educational interruptions were a stressor among adults with serious distress attending college and/or with (69 percent).

New study shows staggering effect of coronavirus pandemic on America’s mental health

Posted by in categories: biotech/medical, health, neuroscience

When the novel coronavirus roared into the U.S., mental health took a back seat to physical health. The number one priority was making sure hospitals wouldn’t be overwhelmed and that as many lives as possible could be saved.

Schools closed, remote work became the norm, restaurants shuttered and getting together with friends was no longer possible. The news cycle spun with story after story highlighting the ever-increasing number of cases and deaths, while unemployment soared to levels not seen since the Great Depression.

Any one of these shifts could be expected to cause an increase in issues. Put together, they created a a perfect storm for a crisis.

The omicron subvariant now dominating the US is ‘the worst version of the virus that we’ve seen’

Posted by in categories: biotech/medical, health

New immune-evading Omicron subvariant BA.5 is now dominant in the U.S.—and previous heavy hitter “stealth Omicron” is now a shadow of its former self, according to federal health data released Tuesday.

BA.5 is estimated to have caused nearly 54% of COVID infections in the U.S. last week, according to data from the U.S. Centers for Disease Control and Prevention. Along with twin variant BA.4, it swept South Africa this spring thanks to its ability to evade immunity from both prior infection and vaccination.

The week before that, the two variants combined made up slightly more than half of U.S. cases. But last week, BA.5 accomplished the same feat alone, without the help of BA.4, which came in third at 16.5%.

New gene profiling technology reveals melanoma biomarkers

Posted by in categories: biotech/medical, evolution, health

A new UC Davis-led study sheds light on cell type-specific biomarkers, or signs, of melanoma. The research was recently published in the Journal of Investigative Dermatology.

Melanoma, the deadliest of the common skin cancers, is curable with and treatment. However, diagnosing clinically and under the microscope can be complicated by what are called melanocytic nevi—otherwise known as birth marks or moles that are non-cancerous. The development of melanoma is a multi-step process where “melanocytes,” or the cells in the skin that contain melanin, mutate and proliferate. Properly identifying melanoma at an early stage is critical for improved survival.

“The biomarkers of early melanoma evolution and their origin within the tumor and its microenvironment are a potential key to early diagnosis of melanoma,” said corresponding author of the study Maija Kiuru, associate professor of clinical dermatology and pathology at UC Davis Health. “To unravel the mystery, we used high-plex spatial RNA profiling to capture distinct gene expression patterns across cell types during melanoma development. This approach allows studying the expression of hundreds or thousands of genes without disrupting the native architecture of the tumor.”

Graphene tattoo provides cuffless blood pressure monitoring

Posted by in categories: biotech/medical, health

Near-invisible graphene tattoos deliver high-speed and long-term continuous monitoring of blood pressure with high accuracy.

Wrapping a cuff around a patient’s arm and inflating it to measure blood pressure is one of the most routinely performed medical tests. It provides a quick and reliable assessment of cardiovascular health, as blood pressure is an independent predictor of all-cause mortality. But such arm cuffs are bulky and uncomfortable, making them impractical for continuous monitoring outside of clinics.

For this reason, researchers are developing cuffless alternatives with the goal of unlocking new possibilities for patient diagnostics and management, as well as providing new understanding of physiology. However, none of these tools has become a mainstay yet.

Chinese researchers develop AI that can read minds and determine party loyalty, report reveals

Posted by in categories: health, robotics/AI

Chinese researchers have reportedly developed artificial intelligence (AI) that can read the minds of Chinese Communist Party (CCP) officials.

A video report detailed the software’s features and attributed it to the Hefei Comprehensive National Science Center, a relatively new institute focused on health and environment, energy research, information management and artificial intelligence.

The technology essentially tests one’s level of loyalty to the CCP. According to the center, it would “further solidify their [members’] confidence and determination to be grateful to the party, listen to the party and follow the party.”

A model that allows robots to follow and guide humans in crowded environments

Posted by in categories: health, robotics/AI, transportation

Assistance robots are typically mobile robots designed to assist humans in malls, airports, health care facilities, home environments and various other settings. Among other things, these robots could help users to find their way around unknown environments, for instance guiding them to a specific location or sharing important information with them.

While the capabilities of assistance robots have improved significantly over the past decade, the systems that have so far been implemented in real-world environments are not yet capable of following or guiding humans efficiently within crowded spaces. In fact, training robots to track a specific user while navigating a dynamic environment characterized by many randomly moving “obstacles” is far from a simple task.

Researchers at the Berlin Institute of Technology have recently introduced a new model based on deep reinforcement learning that could allow to guide a specific user to a desired location or follow him/her around while carrying their belongings, all within a crowded environment. This model, introduced in a paper pre-published on arXiv, could help to significantly enhance the capabilities of robots in malls, airports and other public places.

Mimicking the function of Ruffini receptors using a bio-inspired artificial skin

Posted by in categories: biological, cyborgs, habitats, health, robotics/AI

Mobile robots are now being introduced into a wide variety of real-world settings, including public spaces, home environments, health care facilities and offices. Many of these robots are specifically designed to interact and collaborate with humans, helping them to complete hands-on physical tasks.

To improve the performance of on interactive and manual tasks, roboticists will need to ensure that they can effectively sense stimuli in their environment. In recent years, many engineers and material scientists have thus been trying to develop systems that can artificially replicate biological sensory processes.

Researchers at Scuola Superiore Sant’Anna, Ca’ Foscari University of Venice, Sapienza University of Rome and other institutes in Italy have recently used an artificial skin and a that could be used to improve the tactile capabilities of both existing and newly developed robots to replicate the function of the so-called Ruffini receptors. Their approach, introduced in a paper published in Nature Machine Intelligence, replicates the function of a class of cells located on the human superficial dermis (i.e., subcutaneous skin tissue), known as Ruffini receptors.
