Brain-Controlled Exoskeleton Enables Paralyzed Patient to Walk The device cannot be used outside of the lab yet, but the outcomes are bright. Aquadriplegic patient has walked again acknowledgments to a brain-controlled robotic exoskeleton suit being well-tried in the lab, according to a group of investigators in France. Their assemblage were published (October 3) in The Lancet Neurology. Thibault (whose last name was withheld for privacy), 28 years old at the occurrence of the two-year study, was paralyzed from the shoulders down after a cervical spinal cord injury. Researchers constituted two recording devices on the surface of his brain to accumulate and transmit brain signals. The signals were interpreted into motions with a decoding algorithm, which then sent commands to the exoskeleton. Thibault was able to complete various movement tasks such as walking and reaching for targets, according to a press release.

Cells’ Oxygen Sensory Activity Disclosure Gains Nobel Prize

Posted Leave a commentPosted in Research, Science

This year’s Nobel Prize in Physiology or Medicine goes to William Kaelin of the Dana-Farber Cancer Institute and Harvard Medical School, Peter Ratcliffe of the University of Oxford and the Francis Crick Institute, and Gregg Semenza of the Johns Hopkins University School of Medicine “for their discoveries of how cells sense and adapt to oxygen availability,” the Nobel Assembly at the Karolinska Institute announced today (October 7). See “Seeking a Cellular Oxygen Sensor” In 1995, Semenza’s lab was the first to identify the genes that encode hypoxia-inducible factor-1 (HIF-1), a transcription factor that alters cellular responses to low oxygen. His group found that HIF-1 responds to low oxygen levels by controlling which genes are used in a cell. The protein enables cancer cells to live in the low-oxygen conditions found within tumors, and helps the body respond to cardiovascular events that limit oxygen flow to parts of the body.

The genome of almost 5000-year-elderly woman associates present-day Indians to antiquated civilization

At generally a similar time that old Egyptians were developing their first extraordinary pyramids and Mesopotamians were building amazing sanctuaries and ziggurats, the Harappans of South Asia—otherwise called the Indus Valley Civilization—were raising monstrous heated block lodging edifices and cutting elaborate trench frameworks. The development’s sudden ruin stays one of the extraordinary puzzles of the old world. Presently, just because, researchers have dissected the genome of an old Harappan. The discoveries uncover minimal regarding why the society crumbled, yet they light up the two its past and its proceeding with hereditary inheritance in present day Indians.

“The Indus Valley Civilization has been a mystery for quite a while,” says Priya Moorjani, a populace geneticist at the University of California, Berkeley, who wasn’t engaged with the examination. “So it’s energizing to … find out about its family and history.”

The Indus Valley Civilization developed at some point around 3000 B.C.E. what’s more, had crumpled by around 1700 B.C.E. During its stature, it extended crosswise over quite a bit of what is today northwestern India and parts of eastern Pakistan. It is then again known as the Harappan human progress, after the first of its destinations to be unearthed in Punjab region in Pakistan starting during the 1820s. Alongside old Egypt and Mesopotamia, it was among the world’s first enormous scale urban agrarian social orders, flaunting somewhere close to 1 million and 5 million occupants crosswise over five central urban communities.

Albeit several skeletons from the Indus Valley have been revealed, the area’s hot atmosphere quickly obliterates the genetic material that has been instrumental in following the historical backdrop of other early civic establishments.
