Age-related heart disease linked to gut bacteria metabolite

Posted by in categories: biotech/medical, chemistry, food, life extension

New research from the University of Colorado Boulder has offered some of the clearest evidence to date showing how the gut microbiome produces a metabolite that, over time, contributes to age-related declines in cardiovascular health.

High blood levels of trimethylamine-N-Oxide (TMAO), a metabolic byproduct of digestion, have been strongly linked to negative cardiovascular health. When one eats red meat, eggs or other animal proteins, certain types of gut bacteria feed on chemicals in those foods and produce TMA, or trimethylamine, which is then turned into TMAO in the liver.

A number of studies have linked TMAO to heart disease, however, until now it hasn’t been clear exactly how this metabolite causes cardiovascular damage. A robust new study, published in the journal Hypertension, is offering one of the first thorough mechanistic investigations illustrating how TMAO damages the cardiovascular system.

Rare brain-eating amoeba infection confirmed in Florida, health officials say

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

A person in Florida has been infected with a rare and usually deadly brain-eating amoeba, according to health officials.

The Florida Department of Health announced Friday that one patient in Hillsborough County has been infected with Naegleria fowleri, a water-borne, microscopic single-celled amoeba that attacks the brain.

“Infections can happen when contaminated water enters the body through the nose,” the health department said.

Tesla’s $20,000 Compact Car — Coming Soon After Tesla Battery Day Reveals New Batteries

Posted by in categories: Elon Musk, media & arts, sustainability, transportation

Tesla is working on a compact car that will be manufactured in China and distributed worldwide. The battery technologies required for a compact car will be unveiled at Tesla Battery Day that will enable Tesla to make a small car for less than $25,000, possibly close to $20,000 or less. The battery cost is the main factor to drive down the cost of an electric vehicle. The compact car is coming soon after Tesla Battery Day technologies are revealed. The new batteries will allow Tesla to shrink the battery pack’s size while offering enough range for everyday driving. Elon Musk’s speech at the launch event in China suggests the car will be quite unique, just like the Cybertruck.

Luke Aikins No Parachute 25,000 Feet Airplane Jump Complete Video

Posted by in category: transportation

Stride Gum Presents Heaven Sent
Luke Aikins, the first person to accomplish a planned jump out of an airplane without a parachute or wing suit from a very high altitude (25,000 feet) (7,620 meters). Aikins eventually lands in a net.

“Jumpers are away. Now he’s practicing the flip. That’s how he’ll have to land. He’ll have to land on his back. At 18,000 feet the oxygen mask will come off. There goes the oxygen mask. Now at 12,000 feet he’ll hear a beep in his helmet that will tell him he’s halfway home.”

A biohybrid synapse with neurotransmitter-mediated plasticity

Posted by in categories: biological, chemistry, robotics/AI, sustainability

Brain-inspired computing paradigms have led to substantial advances in the automation of visual and linguistic tasks by emulating the distributed information processing of biological systems. The similarity between artificial neural networks (ANNs) and biological systems has inspired ANN implementation in biomedical interfaces including prosthetics and brain-machine interfaces. While promising, these implementations rely on software to run ANN algorithms. Ultimately, it is desirable to build hardware ANNs that can both directly interface with living tissue and adapt based on biofeedback. The first essential step towards biologically integrated neuromorphic systems is to achieve synaptic conditioning based on biochemical signalling activity. Here, we directly couple an organic neuromorphic device with dopaminergic cells to constitute a biohybrid synapse with neurotransmitter-mediated synaptic plasticity. By mimicking the dopamine recycling machinery of the synaptic cleft, we demonstrate both long-term conditioning and recovery of the synaptic weight, paving the way towards combining artificial neuromorphic systems with biological neural networks.
