1 thought on “Insights into the Neurobiology of Death”

Posted by in categories: biotech/medical, neuroscience

A recent study gives insight into the #neurobiology of dying. Before the process of dying neurologists closely monitored patients with devastating #brain injuries following Do Not Resuscitate-Comfort Care orders. This gave key insights into the mechanisms and timing of events in the brain and the circulatory system during the dying process.

The objective of emergency treatment is to restore circulation to prevent #cerebral ischemia. #Cerebral ischemia is a condition that occurs when blood flow is restricted to the brain, which then causes the #death of brain tissue. Understanding the brain’s response to energy depletion can help us estimate how much time is available for resuscitation until irreversible damage has occurred. The goal is to develop methods that can prolong this window before irreversible damage takes place. Injury to central neurons begins only during the progressive and uncontrollable #depolarization of neurons called anoxic depolarization. This Anoxic depolarization “wave” is potentially reversible and typically starts 2 to 5 minutes after the emergence of severe ischemia. This marks the beginning of a toxic change within the neuron which eventually leads to irreversible brain injury.

A Magnetic ‘Wormhole’ That Connects Two Regions of Space Was Created in The Lab

Posted by in categories: cosmology, physics, space travel

Back in 2015, researchers in Spain created a tiny magnetic wormhole for the first time ever. They used it to connect two regions of space so that a magnetic field could travel ‘invisibly’ between them.

Before you get too excited, it wasn’t the kind of gravitational wormhole that would theoretically allow humans to travel rapidly across space in science fiction TV shows and films such as Stargate, Star Trek, and Interstellar, and it wouldn’t have been able to transport matter.

But the physicists managed to create a tunnel that allowed a magnetic field to disappear at one point, and then reappear at another, which is still a pretty huge deal.

This New Hybrid Solar Cell Can Harvest Electricity From Actual Raindrops

Posted by in categories: solar power, sustainability, transportation

As advanced and efficient as our solar panels are becoming, they’re still pretty much useless when rain clouds arrive overhead. That could soon change thanks to a hybrid cell that can harvest energy from both sunlight and raindrops.

The key part of the system is a triboelectric nanogenerator or TENG, a device which creates electric charge from the friction of two materials rubbing together, as with static electricity – it’s all about the shifting of electrons.

TENGs can draw power from car tyres hitting the road, clothing materials rubbing up against each other, or in this case the rolling motion of raindrops across a solar panel. The end result revealed by scientists from Soochow University in China is a cell that works come rain or shine.
