Dr Aubrey de Grey doesn’t just believe that aging, and the suffering that comes with it, can be slowed down — he believes it can be undone altogether.

What’s more, he thinks we are merely a few years away from making the scientific breakthroughs that will enable the medical field to put an end to death related to ageing — for good.

His independently funded non-profit, the SENS Foundation, is at the forefront of radical research that combines the problem solving approaches of technology with geriatric medicine.

In this conversation, he talks to Rob about his refusal to age gracefully, the biases of modern science, immortality, and why he won’t waste his time thinking about whether or not God exists.

If scientists could find a way to control the process for making semiconductor components on a nanometric scale, they could give those components unique electronic and optical properties—opening the door to a host of useful applications.

Researchers at the Laboratory of Microsystems, in EPFL’s School of Engineering, have taken an important step towards that goal with their discovery of semiconducting nanotubes that assemble automatically in solutions of metallic nanocrystals and certain ligands. The tubes have between three and six walls that are perfectly uniform and just a few atoms thick—making them the first such nanostructures of their kind.

What’s more, the nanotubes possess photoluminescent properties: they can absorb light of a specific wavelength and then send out intense light waves of a different color, much like and quantum wells. That means they can be used as in , for example, or as catalysts in photoreduction reactions, as evidenced by the removal of the colors of some organic dyes, based on the results of initial experiments. The researchers’ findings have made the cover of ACS Central Science.

Data from Mental Work project, conducted as an experimental artwork at EPFL’s Artlab, indicates that BMI is robust and accessible to the general public, spurring new research collaborations in Switzerland on user experience.

Brain-machine interfaces are rarely found outside of medical clinics, where the disabled receive hours or days of training in order to operate wheelchairs with their minds. Now the largest-ever BMI experiment Mental Work, conducted as an experimental artwork at EPFL’s Artlab, has provided preliminary evidence that training time can be shortened, the use of dry electrodes are a robust solution for public BMI and that user performance tends to improve within a relatively short period of time. The still-to-be-published results suggest that BMI may soon reach a much larger and more diverse population. A new collaboration between the Foundation Campus Biotech Geneva, the EPFL and the HEIG-VD in Yverdon will build on the promising results will build on the promising results of Mental Work to further develop user-friendly and publicly accessible interfaces to interact with the physical and digital world using only one’s mind.

“This is the first demonstration that installation art can be used as an experimental platform for breakthrough science,” says Jonathon Keats, the artist and experimental philosopher who conceptualized Mental Work.

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 who had suffered rendering them tetraplegic underwent several operations and intense physiotherapy in the largest ever application of a technique known as .

A team of surgeons succeeded in attaching individual nerves from above the zone of the spinal 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.
