A network of government-funded labs has spent the past 15 years searching for a drug that can slow down aging. The results have researchers excited.

Surgeons in Australia have managed to restore arm function in paralysed patients, allowing them to feed themselves, use tools and handle electronic devices, according to the results of a groundbreaking study released Friday.
Thirteen young adults who had suffered spinal injuries rendering them tetraplegic underwent several operations and intense physiotherapy in the largest ever application of a technique known as nerve transfer surgery.
A team of surgeons succeeded in attaching individual nerves from above the zone of the spinal injury to nerves below the trauma site. The functioning nerves were then used to stimulate paralysed muscles below the injury zone.
The regions and lobes of the brain are identified along with some of the nerves and vessels. The basic functions of the cortex of each lobe are introduced along with principal sulci and gyri. The importance of the left hemisphere for language and the temporal lobe in memory are mentioned along with the concept of cortical localisation. A classical frontal section is used to demonstrate grey and white matter along with the primary internal structures. The brain is one of the largest and most complex organs in the human body. It is made up of more than 100 billion nerves that communicate in trillions of connections called synapses. The brain is made up of many specialised areas that work together: The cortex is the outermost layer of brain cells. the human brain is explained in this video. Full documentary of the human brain.
Sleep is essential to all animals with a nervous system. Nevertheless, the core cellular function of sleep is unknown, and there is no conserved molecular marker to define sleep across phylogeny. Time-lapse imaging of chromosomal markers in single cells of live zebrafish revealed that sleep increases chromosome dynamics in individual neurons but not in two other cell types. Manipulation of sleep, chromosome dynamics, neuronal activity, and DNA double-strand breaks (DSBs) showed that chromosome dynamics are low and the number of DSBs accumulates during wakefulness. In turn, sleep increases chromosome dynamics, which are necessary to reduce the amount of DSBs. These results establish chromosome dynamics as a potential marker to define single sleeping cells, and propose that the restorative function of sleep is nuclear maintenance.
First published in 2016, predictors of chronological and biological age developed using deep learning (DL) are rapidly gaining popularity in the aging research community.
These deep aging clocks can be used in a broad range of applications in the pharmaceutical industry, spanning target identification, drug discovery, data economics, and synthetic patient data generation. We provide here a brief overview of recent advances in this important subset, or perhaps superset, of aging clocks that have been developed using artificial intelligence (AI).
It sounds like science fiction: a device that can reconnect a paralyzed person’s brain to his or her body. But that’s exactly what the experimental NeuroLife system does. Developed by Battelle and Ohio State University, NeuroLife uses a brain implant, an algorithm and an electrode sleeve to give paralysis patients back control of their limbs. For Ian Burkhart, NeuroLife’s first test subject, the implications could be life-changing.

Cholesterol does not cause heart disease in the elderly and trying to reduce it with drugs like statins is a waste of time, an international group of experts has claimed.
A review of research involving nearly 70,000 people found there was no link between what has traditionally been considered “bad” cholesterol and the premature deaths of over 60-year-olds from cardiovascular disease.
Published in the BMJ Open journal, the new study found that 92 percent of people with a high cholesterol level lived longer.
Music has proven time and again to be an important component of human culture. From its ceremonial origin to modern medical usage for personal motivation, concentration, and shifting mood, music is a powerful balm for the human soul. Though traditional “music therapy” encompasses a specific set of practices, the broader use of music as a therapeutic tool can be seen nowadays as doctors are found recommending music for a wide variety of conditions.
CHICAGO, July 2 (Xinhua) — With a light-spinning device inspired by the Japanese art of paper cutting, researchers at the University of Michigan (UM) have detected microscopic twists in the internal structure of plant and animal tissue without harmful X-rays.
The approach is the first that can fully rotate terahertz radiation in real time, and could open new dimensions in medical imaging, encrypted communications and cosmology, according to a news release posted on UM’s website on Monday.
With an eye to exploring how chirality may help distinguish tissues, the researchers gathered everyday biological materials to look for differences in the absorption of clockwise- or counter-clockwise-rotating radiation in the terahertz spectrum. They studied a maple leaf, a dandelion flower, pork fat and the wing case of an iridescent beetle.
Thomas Durcan’s lab is growing 3D mini-brains in the search for a cure for Parkinson’s disease. Over the next year he is giving all his lab’s protocols, methods and results away.
