Superconducting nanotechnology is a rapidly developing field with a series of promising applications in the field of new quantum technologies such as advanced superconducting quantum processors based on qubits with Josephson tunnel junctions.

Recently, an international team of researchers – with participation of Leibniz Institute of Photonic Technology (Leibniz IPHT) – has demonstrated and published yet another quantum mechanical effect in superconductors – the photon assisted coherent quantum phase slip effect in a very thin superconducting nanowire. The effect is revealed as the formation of current steps on the current-voltage characteristic subject to microwave radiation (Nature, “Quantized current steps due to the a.c. coherent quantum phase-slip effect”).

This effect has been theoretically predicted more than thirty years ago and hints of the current steps of this type have been previously observed in small size Josephson junctions. Switching from a Josephson junction to a superconducting nanowire made of thin films of high-quality niobium nitride allowed the researchers to observe sharp and distinct steps on the current voltage characteristic located at current values I n = 2efn, where 2e is the electric charge of a so-called Cooper pair of two electrons, f the frequency of microwave radiation, and n as an integer number, denoting the step order.

Scientists announced Tuesday that they have for the first time produced more energy in a fusion reaction than was used to ignite it—a major breakthrough in the decades-long quest to harness the process that powers the sun.

Researchers at the Lawrence Livermore National Laboratory in California achieved the result last week, the Energy Department said. Known as a net energy gain, the goal has been elusive because fusion happens at such high temperatures and pressures that it is incredibly difficult to control.

The breakthrough will pave the way for advancements in national defense and the future of clean power, Energy Secretary Jennifer Granholm and other officials said.

Neurotechnology and Brain-Computer Interfaces are advancing at a rapid pace and may soon be a life-changing technology for those with limited mobility and/or paralysis. There are already two brain implants, Blackrock Neurotech’s NeuroPort and Synchron’s Stentrode, that have been approved to start clinical trials under an Investigational Device Exemption. In this video, we compare these devices on the merits of safety, device specifications, and capability.

Thanks to Blackrock Neurotech for sponsoring this video. The opinions expressed in this video are that of The BCI Guys and should be taken as such.

The chronic nature and associated complications of nonhealing wounds have led to the emergence of nanotechnology-based therapies that aim at facilitating the healing process and ultimately repairing the injured tissue. A number of engineered nanotechnologies have been proposed demonstrating unique properties and multiple functions that address specific problems associated with wound repair mechanisms. In this outlook, we highlight the most recently developed nanotechnology-based therapeutic agents and assess the viability and efficacy of each treatment, with emphasis on chronic cutaneous wounds. Herein we explore the unmet needs and future directions of current technologies, while discussing promising strategies that can advance the wound-healing field.

For many of us, the act of breathing comes naturally. Behind the scenes, our diaphragm — the dome-shaped muscle that lies just beneath the ribcage — works like a slow and steady trampoline, pushing down to create a vacuum for the lungs to expand and draw air in, then relaxing as air is pushed out. In this way, the diaphragm automatically controls our lung capacity, and is the major muscle responsible for our ability to breathe.

But when the diaphragm’s function is compromised, the breathing instinct becomes a laborious task. Chronic diaphragm dysfunction can occur in people with ALS, muscular dystrophy, and other neuromuscular diseases, as well as patients with paralysis, and damage to the phrenic nerve, which stimulates the diaphragm to contract.

Two doctors at the Max Super Specialty Hospital in India has documented the filarial dance of scrotal worms on video. In the video, the undulations of live worms residing in a male patient’s scrotum can be seen.

The case study began as a 26-year-old man came to the hospital complaining of testicular pain. He told them it was associated with swelling of his scrotum and had been bothering him for approximately one month. He also had a slight fever. Suspecting some type of parasite, the doctors first examined the man using ultrasound after which they extracted some of the fluid that had built up in the scrotum for inspection by lab techs. They also took blood samples for the same purpose.
