in order to reduce power consumption when transmitting and receiving information, wireless systems need to send signals that can easily travel from one side of the human body to another.
so signals are communicated with much lower path losses and potentially, much lower power consumption. In their experiments, researchers demonstrated that the magnetic communication link works well on the body,
but they did not test the technique's power consumption. Researchers showed that the path losses associated with magnetic field human body communication are upwards of 10 million times lower than those associated with Bluetooth radios."
Lower power consumption also leads to longer battery life.""A problem with wearable devices like smart watches is that they have short operating times
With this magnetic field human body communication system, we hope to significantly reduce power consumption as well as how frequently users need to recharge their devices,

#Loss of cellular energy leads to neuronal dysfunction in neurodegenerative disease model A new study from the Gladstone Institutes shows for the first time that impairments in mitochondria--the brain's cellular power plants--can deplete cellular energy levels
A link between mitochondria, energy failure, and neurodegeneration has long been hypothesized. However, no previous studies were able to comprehensively investigate the connection because sufficiently sensitive tests,
the scientists created novel assays to more accurately measure the brain's energy production. Using a model of Leigh's disease,
the researchers tested energy levels in neurons using the new assays. They found that the genetic mutation associated with Leigh's disease compromised ATP levels,
"It was assumed always that defects in mitochondria would result in a depletion of energy levels,
the researchers also determined the energy threshold needed to support synaptic vesicle cycling--the process by
so that the cells had to rely solely on their mitochondria for energy. This allowed the researchers to more accurately assess the contribution of mitochondrial ATP to different steps in the cycle,
From this exploration, the scientists revealed that bringing the vesicles back up into the cell after they have released their neurotransmitters is the most energy-demanding process.
The researchers also compared energy levels in boutons--the docks from which neurotransmitters are shipped--with and without mitochondria.
Remarkably, there was no difference in energy levels between the two, and both types of boutons had sufficient ATP to support synaptic vesicle cycling.
so that even those boutons lacking mitochondria have sufficient energy to function under normal conditions. They note it will be important to determine

When the Big bang created the energy of the universe about 13.8 billion years ago, some portion of that energy found itself locked up as mass.
When stars shine they are converting that mass back into energy, as described by Albert Einstein's famous equation E=mc2 (energy=mass x speed of light squared).
From the Big bang to Now in 10 Easy Steps"While most of the energy sloshing around in the universe arose in the aftermath of the Big bang,
additional energy is constantly being generated by stars as they fuse elements like hydrogen and helium together,
"Driver said.""This new energy is absorbed either by dust as it travels through the host galaxy,
or escapes into intergalactic space and travels until it hits something, such as another star, a planet,
