Futuristic AI-Based Computing Devices: Physicists Simulate Artificial Brain Networks With New Quantum Materials

Posted by in categories: biotech/medical, quantum physics, robotics/AI, supercomputing

Pandemic lockdown forces a new perspective on designs for futuristic AI-based computing devices.

Isaac Newton’s groundbreaking scientific productivity while isolated from the spread of bubonic plague is legendary. University of California San Diego physicists can now claim a stake in the annals of pandemic-driven science.

A team of UC San Diego researchers and colleagues at Purdue University have now simulated the foundation of new types of artificial intelligence computing devices that mimic brain functions, an achievement that resulted from the COVID-19 pandemic lockdown. By combining new supercomputing materials with specialized oxides, the researchers successfully demonstrated the backbone of networks of circuits and devices that mirror the connectivity of neurons and synapses in biologically based neural networks.

Mr. Jack Sim — Founder, World Toilet Organization — Ending The Global Sanitation Crisis

Posted by in categories: biotech/medical, food, security

Ending the global sanitation crisis — jack sim, founder world toilet organization.


Around 2 billion people worldwide still lack access to the basic tools of improved sanitation (toilets and latrines). One billion people still have to defecate in the open, and at least 10% of the world’s population is thought to consume food irrigated by raw wastewater. An estimated 800,000 children, younger than 5 years of age, perish from diarrhea each year, including conditions related to cholera, dysentery, hepatitis A, typhoid and polio.

Fixing protein production errors lengthens lifespan

Posted by in categories: biotech/medical, life extension

Reducing naturally occurring errors in protein synthesis (production) improves both health and lifespan, finds a new study in simple model organisms led by researchers at UCL and MRC London Institute of Medical Sciences.

The novel findings, published in Cell Metabolism, are the first to demonstrate a direct link between fewer mistakes and longevity.

Explaining the study, lead author Dr. Ivana Bjedov (UCL Cancer Institute), said: We commonly hear about DNA mutations, which can cause cancer, and are considered one of the underlying causes of ageing.

Scientists Claim Overeating Is Not the Primary Cause of Obesity — Point to More Effective Weight Loss Strategies

Posted by in categories: biotech/medical, health

In contrast to the energy balance model, the carbohydrate-insulin model makes a bold claim: overeating isn’t the main cause of obesity. Instead, the carbohydrate-insulin model lays much of the blame for the current obesity epidemic on modern dietary patterns characterized by excessive consumption of foods with a high glycemic load: in particular, processed, rapidly digestible carbohydrates. These foods cause hormonal responses that fundamentally change our metabolism, driving fat storage, weight gain, and obesity.


Perspective published in The American Journal of Clinical Nutrition argues the root causes of the obesity epidemic are more related to what we eat rather than how much we eat.

Statistics from the Centers for Disease Control and Prevention (CDC) show that obesity affects more than 40% of American adults, placing them at higher risk for heart disease, stroke, type 2 diabetes, and certain types of cancer. The USDA’s Dietary Guidelines for Americans 2020 – 2025 further tells us that losing weight “requires adults to reduce the number of calories they get from foods and beverages and increase the amount expended through physical activity.”

This Common Drug for Memory Loss May Also Help Restore Eye Sight

Posted by in categories: biotech/medical, life extension, neuroscience

Citicoline, a drug that is naturally found in the body, is commonly used to treat a number of brain injuries and illnesses. For quite some time, doctors have prescribed it for strokes, vascular dementia, Parkinson’s disease, and general aging of the brain. Patients usually see improvement when taking the drug because the body uses it to create and repair cell membranes and lower the presence of free radicals, as noted in the Clinical Interventions in Aging Journal. (Free radicals, which are unstable molecules, can damage cells in the body and are associated with aging and illness.)

Now, researchers from the NYU Grossman School of Medicine have found evidence that citicoline can also be used to treat glaucoma. Normally, glaucoma is treated by removing fluid buildup in the eye, which creates pressure and wears down the cells in the eye and the nerves connecting to the brain. Though monitoring fluid buildup is important, glaucoma can still worsen after the pressure on the eye has been relieved.

Study Finds Evidence of Possible Link Between Herpes Simplex and Neurogenerative Diseases

Posted by in categories: biotech/medical, genetics, life extension, neuroscience

Because the herpesvirus sits in neurons forever, there is speculation it is connected to neurodegenerative diseases. The immune system requires inflammation to constantly fight off the virus, and neurons have some degree of damage because of this continuous immune response, according to Dr. Tibor Valyi-Nagy, professor of pathology, director of neuropathology at UIC and research collaborator on the study.


Summary: Researchers discovered mutations of the OPTN gene resulted in increased herpesvirus 1 growth in the brains of mice, leading to the death of local neurons. This resulted in accelerated neurodegeneration. OPTN deficiency was also associated with impairments in immune response. While these findings are specific to the HSV-1 virus, researchers believe the findings may apply to up to eight herpesvirus infections.

Instrumental: Engineers Who Make Science Possible (Live Public Talk)

Pollution creates particulate matter (tiny floating particles) and aerosols that can be harmful to our health. With missions like the Multi-Angle Imager for Aerosols (MAIA), public health officials can start to map this particulate matter around the world, understand its effect on diseases, and know where the most risk is. In this month’s talk, we’ll chat with the instrument operations systems engineer for MAIA and discuss how vital positions like hers are for mission success and for making sure important data gets back to us on Earth.

Britain’s young teens will be vaccinated

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

Britain’s young teens will be vaccinated — but with a single dose.


London: Britain’s chief medical officers have said that vaccinating young teenagers against COVID-19 is justified when their mental health and education are taken into account.

Minors aged between 12 and 15 in England will be offered just a single dose of Pfizer or Moderna beginning next week, with more research ordered into whether a second dose should be given, as is currently administered to those aged 16 and above.

Do we need humans for that job? Automation booms after COVID

Posted by in categories: biotech/medical, employment, health, robotics/AI

Automation will drag on at the normal pace. 2025 i think will be the key year, where Human Level hands could turn up on the humanoid robots, and an early phase of Human Level AI turns up; if those 2 things happen automation of jobs will really start to move fast.


Ask for a roast beef sandwich at an Arby’s drive-thru east of Los Angeles and you may be talking to Tori — an artificially intelligent voice assistant that will take your order and send it to the line cooks.

“It doesn’t call sick,” says Amir Siddiqi, whose family installed the AI voice at its Arby’s franchise this year in Ontario, California. “It doesn’t get corona. And the reliability of it is great.”

Israeli scientists aim to mobilize allergy-causing cells to fight cancer

Posted by in categories: biotech/medical, health

Israeli scientists are harnessing the “destructive” qualities of allergy-causing cells, as part of a bold attempt to pioneer a new immunotherapy for fighting cancer. A research team from Tel Aviv University has found that eosinophils, white blood cells that induce allergies, significantly reduce the growth of human tumors in vitro, and mouse tumors in the body. Nine days after mice were injected with eosinophils, the overall size of tumors per mouse averaged half that of mice who weren’t injected.


Tumors in mice lost half their size when injected with eosinophils, best known for inducing allergies; promising results also seen in human tumor cells in vitro.
