CLEW, an Israeli medtech firm specializing in real-time AI analytics platforms, received approval from the United States Food and Drug Administration (FDA) for its “Predictive Analytics Platform in Support of COVID-19 Patients,” the company announced Tuesday.
The Intensive Care Unit (ICU) solution was given Emergency Use Authorization (EUA) by the FDA so that it may be implemented within the United States’ health system as soon as possible.
In other words, practicing the arts can be used to build capacity for managing one’s mental and emotional well-being.
Neuroesthetics — With recent advances in biological, cognitive, and neurological science, there are new forms of evidence on the arts and the brain. For example, researchers have used biofeedback to study the effects of visual art on neural circuits and neuroendocrine markers to find biological evidence that visual art promotes health, wellness, and fosters adaptive responses to stress.
Data governs our lives more than ever. But when it comes to disease and death, every data point is a person, someone who became sick and needed treatment.
Recent studies have revealed that people suffering from the same disease category may have different manifestations. As doctors and scientists better understand the reasons underlying this variability, they can develop novel preventive, diagnostic and therapeutic approaches and provide optimal, personalized care for every patient.
To accomplish this goal often requires broadscale collaborations between physicians, basic researchers, theoreticians, experimentalists, computational biologists, computer scientists and data scientists, engineers, statisticians, epidemiologists and others. They must work together to integrate scientific and medical knowledge, theory, analysis of medical big data and extensive experimental work.
This year, the Israel Precision Medicine Partnership (IPMP) selected 16 research projects to receive NIS 60 million in grants with the goal of advancing the implementation of personalized healthcare approaches – providing the right treatment to the right patient at the right time. All the research projects pull data from Israel’s unique and vast medical databases.
HEALTH AND SCIENCE AFFAIRS: 16 Israeli projects get NIS 60m. to innovate next stage of healthcare.
“Now, nearly 2,000 people in and around Leticia are sick with COVID-19. About 70 have died. That might not sound like a colossal death toll at first. But because the surrounding state of Amazonas is sparsely populated, this amounts to the highest per-capita death rate in all of Colombia, according to figures from Colombia’s Health Ministry.”
The governor of Amazonas, Colombia, says it was impossible to cut the area off from Brazil, even as the virus spiked. Now the Colombian border town of Leticia is a coronavirus hot spot.

Speed as important as size in predicting potentially damaging impacts of coronal mass ejections.
Space weather forecasters need to predict the speed of solar eruptions, as much as their size, to protect satellites and the health of astronauts, scientists have found.
Scientists at the University of Reading found that by calculating the speed of coronal mass ejections (CMEs) when they hit Earth, forecasters could provide more useful early warnings. This would help operators of critical infrastructure such as satellites know if they need to take evasive action or switch off systems to protect them, and warn astronauts when they need to shelter inside shielded parts of the International Space Station.
Miniaturization has enabled technology like smartphones, health watches, medical probes and nano-satellites, all unthinkable a couple decades ago. Just imagine that in the course of 60 years, the transistor has shrunk from the size of your palm to 14 nanometers in dimension, 1000 times smaller than the diameter of a hair.
Miniaturization has pushed technology to a new era of optical circuitry. But in parallel, it has also triggered new challenges and obstacles, for example, controlling and guiding light at the nanometer scale. Researchers are looking for techniques to confine light into extremely tiny spaces, millions of times smaller than current ones. Studies had earlier found that metals can compress light below the wavelength-scale (diffraction limit).
In that aspect, graphene, a material composed from a single layer of carbon atoms, which exhibits exceptional optical and electrical properties, is capable of guiding light in the form of plasmons, which are oscillations of electrons that strongly interact with light. These graphene plasmons have a natural ability to confine light to very small spaces. However, until now, it was only possible to confine these plasmons in one direction, while the actual ability of light to interact with small particles like atoms and molecules resides in the volume into which it can be compressed. This type of confinement in all three dimensions is commonly regarded as an optical cavity.
Regeneron Pharmaceuticals announced Thursday that it’s started the first clinical trial of its experimental coronavirus antibody drug.
The antibody cocktail is being tested in four human populations. Two groups of people will receive the drug to test its effectiveness as a treatment for Covid-19; the other two will receive it as a possible prevention.
“We’ll be hopefully to quickly test the safety and then start understanding the efficacy for four major different settings of this virus challenge,” Regeneron’s chief scientific officer, Dr. George Yancopoulos, said on CNBC’s “Squawk Box.” Yancopoulos said he thinks that, “if all goes well,” the company could have “definitive data” within a few months on the effectiveness of the antibody cocktail.
“I think there’s a lot of reason for hope,” Yancopoulos said, noting the company’s work on Ebola. But he also stressed the unpredictable nature of science and biology, saying “there’s always reasons to be concerned and to be cautious.” “So we’re going to be moving forward very carefully, hand-in-hand in with the FDA, and we hope sooner rather than later we can get answers that can really make a difference,” he said.
Regeneron is the latest company to begin trials for a potential Covid-19 therapy. Eli Lilly, which began trials of its antibody drug earlier this month, said a treatment could be authorized, if all goes well, for use as early as September. In scientific trials so far, Gilead Sciences’s antiviral remdesivir is the only drug to show some effectiveness in treating the disease. There are more than 7.4 million confirmed cases of Covid-19 in the world, including over 2 million in the U.S., according to the latest data from Johns Hopkins University. More than 417,100 people have died worldwide, with over a quarter of the fatalities in the U.S. Regeneron’s drug is being tested on four distinct types of patients, including “the sickest patients” who are hospitalized and on a ventilator or oxygen support, Yancopoulos said. It’s also being tested to see whether it can prevent high-risk people from contracting the disease, such as health-care workers. The drug, known as REGN-COV2, is a combination of two antibodies. Yancopoulos said Regeneron firmly believes this is the correct approach to treat Covid-19 when using antibodies.
“Just like with conventional, old fashion antiviral drugs, giving one can have enormous benefit initially but it can lead to the selection and the arise of escaped viral mutants, which can could be very dangerous and risky,” he said. “What we showed is that in order to prevent this, you have to give these antibodies in cocktails.”
Recent therapeutic trials of “classical” psychedelic drugs, such as psilocybin (from magic mushrooms) or LSD, have reported benefits to wellbeing, depression and anxiety. These effects seem to be linked to a sense of “ego dissolution” — a dissolving of the subjective boundaries between the self and the wider world. However, the neurochemistry behind this effect has been unclear. Now a new paper, published in Neuropsychopharmacology, suggests that changes in brain levels of the neurotransmitter glutamate are key to understanding reports of ego dissolution — and perhaps the therapeutic effects of psychedelics.
Natasha Mason at Maastricht University, the Netherlands, and colleagues recruited 60 participants for their study. All had taken a psychedelic drug before, but not in the three months prior to the study. Half received a placebo and the other half were given a low to moderate dose of psilocybin (0.17 mg/kg of body weight).
The team then used a technique called proton magnetic resonance spectroscopy (MRS) to look at concentrations of glutamate (as well as other neurochemicals) in the medial prefrontal cortex (mPFC) and the hippocampus — two regions that have been implicated as key to the psychedelic drug experience. The team also looked at patterns of “functional connectivity” within networks of brain regions, a measure of how closely correlated brain activity is across those regions. Six hours after taking the drug or placebo, the participants reported on their subjective experiences using two surveys: The 5 Dimensions of Altered States of Consciousness and the Ego Dissolution Inventory.
As the researchers expected (based on the findings of earlier research), those given the drug reported increased feelings of ego dissolution, as well as altered states of consciousness. They also showed disruptions in the connectivity of particular networks, including the default mode network, which has also been implicated in past work on the effects of psychedelic drugs…
But, for the first time in humans, the team also observed higher levels of glutamate in the mPFC and lower levels in the hippocampus after taking psilocybin — and they linked these changes to different aspects of ego dissolution. Increases in the mPFC were most strongly linked to unpleasant aspects, such as a loss of control over thoughts and decision-making, and also anxiety. Decreases in the hippocampus, meanwhile, were most strongly linked to more positive aspects, such as feelings of unity with the wider world, and of having undergone a spiritual-type experience.
The hippocampus is our most important memory structure. Based on earlier work on the impacts of psychedelic drugs on patterns of brain connectivity, it’s been suggested that a temporary reduction or loss of access to memories about our own lives might contribute to a weakening of the “self”. The new work suggests that changes in glutamate levels in the hippocampus might be key to this process.
But if glutamate rises in the mPFC are linked to unpleasant aspects of ego dissolution, and also to anxiety, how does this fit in with trial results finding that psychedelic drugs can treat anxiety disorders?
