New Brain Map Charts Every Component in the Biological Universe

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

It’s easy to see why: as shockingly powerful mini-processors, neurons and their connections—together dubbed the connectome—hold the secret to highly efficient and flexible computation. Nestled inside the brain’s wiring diagrams are the keys to consciousness, memories, and emotion. To connectomics, mapping the brain isn’t just an academic exercise to better understand ourselves—it could lead to more efficient AI that thinks like us.

But often ignored are the brain’s supporting characters: astrocytes—brain cells shaped like stars—and microglia, specialized immune cells. Previously considered “wallflowers,” these cells nurture neurons and fine-tune their connections, ultimately shaping the connectome. Without this long-forgotten half, the brain wouldn’t be the computing wizard we strive to imitate with machines.

In a stunning new brain map published in Cell, these cells are finally having their time in the spotlight. Led by Dr. H. Sebastian Seung at Princeton University, the original prophet of the connectome, the map captures a tiny chunk of the mouse’s visual cortex, less than 1,000 times smaller than a pea. Yet jam-packed inside the map aren’t just neurons; in a technical tour de force, the team mapped all brain cells, their connections, blood vessels, and even the compartments inside cells that house DNA and produce energy.

What might explain Huntington’s Disease?

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

Could 2 B vitamins help those suffering with Huntington’s Disease?


T he Huntington’s disease (HD) community has recently experienced setbacks, but a new research report may reignite hope, from an unexpected source: the vitamin thiamine (B1), with help from biotin (B7). The investigators, from several institutions in Spain and UCLA, write in Science Translational Medicine, “Together, these results demonstrate a thiamine deficiency in HD brain and suggest that individuals with HD might benefit from thiamine and/or biotin supplementation therapy.”

Health care providers may suggest certain supplements for HD patients, based perhaps on a deficiency (vitamins C, B12, E) in the blood, or for general health. But the new findings are different. The researchers didn’t set out to detect a vitamin deficiency, but instead probed the messaging within cells in the HD brain, which led them to a biochemical juncture that revealed the thiamine/biotin connection.

China complains of close encounters with SpaceX Starlink satellites, Conducts preventive maneuvers to avoid collisions

Posted by in categories: Elon Musk, health, internet, satellites

SpaceX Starlink satellites twice approached the Chinese Space Station (CSS) in orbit, prompting China to warn of “close contacts” with Elon Musk’s space program.

Both the July 1 and October 21 incidents prompted the Chinese spacecraft to perform collision avoidance maneuvers. The Chinese team told the UN secretary-general in a diplomatic statement they provided earlier this month that on both occasions there were crew members on board, “which might represent a hazard to the lives or health of astronauts.”

Since its launch on April 29, the CSS “Tiangong” has maintained a nearly circular orbit at a height of around 390 kilometers with an orbital inclination of about 41.5 degrees.

Dr. Adam Wolfberg, MD, MPH — Chief Medical Officer, Current Health — Quality Healthcare In The Home

Posted by in categories: biotech/medical, health, information science, wearables

Is the Chief Medical Officer at Current Health (https://currenthealth.com/), a Best Buy Health company (https://healthcare.bestbuy.com/) and part of the American multinational consumer electronics retailer.

Current Health is an organization that enables the delivery of healthcare services in the home to enable healthcare organizations to deliver high-quality, patient-centric care at a lower cost. The company integrates patient-reported data with data from biosensors – including their own continuous monitoring wearable devices – to provide healthcare organizations with actionable, real-time insights into the patient’s condition. Leveraging clinical algorithms that can be tailored to the individual patient, Current Health identifies when a patient needs clinical attention, allowing organizations to manage patient care remotely or coordinate in-home care via integrated service partners. The Current Health platform brings together tele-health capabilities, patient engagement tools, and in-home connectivity to provide a single solution to manage all care in the home. Dr. Wolfberg also leads implementation and account management at the organization.

Amazon’s voice assistant Alexa to start seeking doctor help

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

If there is no doctor in the house, Amazon’s Alexa will soon be able to summon one.

Amazon and telemedicine provider Teladoc Health are starting a voice-activated virtual care program that lets customers get medical help without picking up their phones.

The service, for health issues that aren’t emergencies, will be available around the clock on Amazon’s Echo devices. Customers can tell the voice assistant Alexa that they want to talk to a doctor, and that will prompt a call back on the device from a Teladoc physician.

New Chip Can Prevent Hackers From Extracting Hidden Information From Smart Devices

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

Engineers build a lower-energy chip that can prevent hackers from extracting hidden information from a smart device.

A heart attack patient, recently discharged from the hospital, is using a smartwatch to help monitor his electrocardiogram signals. The smartwatch may seem secure, but the neural network processing that health information is using private data that could still be stolen by a malicious agent through a side-channel attack.

A side-channel attack seeks to gather secret information by indirectly exploiting a system or its hardware. In one type of side-channel attack, a savvy hacker could monitor fluctuations in the device’s power consumption while the neural network is operating to extract protected information that “leaks” out of the device.

The first controlled study of caloric restriction in humans

Posted by in categories: biotech/medical, health

Decades of research has shown that limits on calorie intake by flies, worms, and mice can enhance lifespan in laboratory conditions. But whether such calorie restriction can do the same for humans has remained unclear. Now a new study led by researchers at Yale University, Connecticut, confirms the health benefits of moderate calorie restrictions in humans – and identifies a key protein that could be harnessed to extend health in humans.

The researchers used data from the Comprehensive Assessment of Long-term Effects of Reducing Intake of Energy (CALERIE) clinical trial, the first controlled study of calorie restriction in healthy humans. For the trial, they established a baseline calorie intake among more than 200 study participants. They then asked a share of those participants to reduce their calorie intake by 14% while the rest continued to eat as usual, and analysed the long-term health effects of calorie restriction over the next two years.

Vishwa Dixit, Professor of Pathology, Immunobiology, and Comparative Medicine, and senior author of the study, said that his team wanted to better understand what calorie restriction does to the body specifically that leads to improved health. Building on previous studies in mice, he and his colleagues set out to determine how it might be linked to inflammation and the immune response.
