Neuropathic pain may result from neuron damage that triggers the production of the “wrong” neurotransmitter. Gene therapy fixes this in mice.
“Ultrasonic frequencies are already being used in destructive procedures like laser ablation of tissues and tumours,” said Prof. Muthukumaran Packirisamy, who led the study along with Dr. Mohsen Habibi and PhD student Shervin Foroughi. “We wanted to use them to create something.”
For instance, utilizing the technique, aircraft mechanics could conceivably 3D-print repairs onto internal components, without opening the plane’s fuselage. It’s even possible that implants could be 3D printed within a patient’s body, without the need for surgery.

Observer, backup youthful copy, playing the right piano notes, quantum states oh my.
Dr David Sinclair explain about through his lab experiments, why he thinks there is an observer/backup copy for our youthfulness and what are the possible identities he can think of in this clip.
Alzheimer’s disease has long thwarted our best efforts to pinpoint its underlying causes. Now, a new study in mice suggests that ‘poisonous flowers’ bulging with cellular debris could be the root source of one hallmark of the wretched disease and a beautifully sinister sign of a failing waste disposal system inside damaged brain cells.
The study, led by neuroscientist Ju-Hyun Lee of New York University (NYU) Langone, challenges the long-standing idea that the build-up of a protein called amyloid-beta between neurons is a crucial first step in Alzheimer’s disease, the most common form of dementia.
Instead, it suggests that damage to neurons may take root inside cells well before amyloid plaques fully form and clump together in the brain, a finding which could provide new therapeutic possibilities.
https://www.kickstarter.com/projects/2125914059/revopoint-mi…m-precison Designers, architects, engineers, we’re all collectively known as creators. The Revopoint MINI handheld 3D scanner just amplifies our creating (or rather re-creating) abilities. Designed to be about the same size as a podcasting microphone (with the tripod and all), Revopoint MINI is an industrial-grade handheld 3D scanner with a staggering precision of 0.02mm. It uses a Class 1 Blue Light that lends it its high accuracy, while still allowing it to be safe on the skin. Just hold it against the object you want to scan and wave it around and like magic, the Revopoint MINI gives you a high-accuracy 3D model, complete with tolerances, textures, and even color information. This makes it perfect for a wide degree of applications, from 3D modeling and animation to medical design, automotive design, jewelry design, even archaeology.
An analysis of drywood termite DNA shows the wood-dwelling insects have crossed the oceans at least 40 times in their history, probably rafting inside driftwood.
New findings were published in the New England Journal of Medicine on Sunday that found all rectal cancer patients given a certain bill were cancer-free.
The New York Times reported the findings, noting that the sample size was incredibly small, with just 18 people but the results were unbelievable.
“I believe this is the first time this has happened in the history of cancer,” said Dr. Luis A. Diaz Jr. of Memorial Sloan Kettering Cancer Center.
Scientists at the Foundation for Applied Molecular Evolution announced today that ribonucleic acid (RNA), an analog of DNA that was likely the first genetic material for life, spontaneously forms on basalt lava glass. Such glass was abundant on Earth 4.35 billion years ago. Similar basalts of this antiquity survive on Mars today.

Use of circulating tumor DNA to guide adjuvant treatment planning for patients with resectable colon cancer led to fewer patients receiving chemotherapy while maintaining outcomes, according to the DYNAMICS study.
The world’s smallest remote-controlled robot is a crab-like object that may be able to help save people during medical procedures.
