Skin patch could painlessly deliver vaccines, cancer medications in one minute

Posted by in category: biotech/medical

Melanoma is a deadly form of skin cancer that has been increasing in the U.S. for the past 30 years. Nearly 100,000 new cases of melanoma are diagnosed every year, and 20 Americans die every day from it, according to the American Academy of Dermatology. Now, researchers have developed a fast-acting skin patch that efficiently delivers medication to attack melanoma cells. The device, tested in mice and human skin samples, is an advance toward developing a vaccine to treat melanoma and has widespread applications for other vaccines.

The researchers will present their findings today at the American Chemical Society (ACS) Fall 2019 National Meeting and Exposition.

“Our has a unique chemical coating and mode of action that allows it to be applied and removed from the skin in just a minute while still delivering a therapeutic dose of drugs,” says Yanpu He, a who helped develop the device. “Our patches elicit a robust antibody response in living mice and show promise in eliciting a strong immune response in .”

Researchers observe spontaneous occurrence of skyrmions in atomically thin cobalt films

Posted by in categories: particle physics, quantum physics, supercomputing

Since their experimental discovery, magnetic skyrmions—tiny magnetic knots—have moved into the focus of research. Scientists from Hamburg and Kiel have now been able to show that individual magnetic skyrmions with a diameter of only a few nanometers can be stabilized in magnetic metal films even without an external magnetic field. They report on their discovery in the journal Nature Communications.

The existence of magnetic skyrmions as particle-like objects was predicted 30 years ago by , but could only be proven experimentally in 2013. Skyrmions with a diameter from micrometers to a few nanometers were discovered in different magnetic material systems. Although they can be generated on a surface of a few atoms and manipulated with , they show a high stability against external influences. This makes them for future data storage or logic devices. In order to be competitive for technological applications, however, skyrmions must not only be very small, but also stable without an applied magnetic field.

Researchers at the universities of Hamburg and Kiel have now taken an important step in this direction. On the basis of quantum mechanical numerical calculations carried out on the supercomputers of the North-German Supercomputing Alliance (HLRN), the physicists from Kiel were able to predict that individual skyrmions with a diameter of only a few nanometers would appear in an atomically thin, ferromagnetic cobalt film (see Fig. 1). “The stability of the magnetic knots in these films is due to an unusual competition between different magnetic interactions,” says Sebastian Meyer, Ph.D. student in Prof. Stefan Heinze’s research group at the Kiel University.

Japan Approves Groundbreaking Experiment Bringing Human-Animal Hybrids to Term

Posted by in categories: bioengineering, biotech/medical, government, law

Stem cell biologist Hiromitsu Nakauchi has been waiting for this moment for more than a decade.

After years of planning, the persistent researcher has at last received approval from a government willing to pursue one of the most controversial scientific studies there is: human-animal embryo experiments.

While many countries around the world have restricted, defunded or outright banned these ethically-fraught practices, Japan has now officially lifted the lid on this proverbial Pandora’s box. Earlier this year, the country made it legal to not only transplant hybrid embryos into surrogate animals, but also to bring them to term.

Meet the XQ-58 Valkyrie: Is This Stealth Drone the Future of the U.S. Air Force?

Posted by in categories: drones, robotics/AI

While the Valkyrie program develops one type of wingman drone, the broader Skyborg program is working on the hardware and software for integrating manned and unmanned fighters.

The U.S. Air Force’s future drone fighter is back in the air.

The XQ-58 Valkyrie on June 11, 2019 took off for its second test flight over Yuma, Arizona. The 29-feet-long, jet-powered drone “successfully completed all test objectives during a 71-minute flight,” the Air Force Research Laboratory announced.

Hubble Celebrates Spitzer’s 16th Birthday

Posted by in category: space

To celebrate NASA’s Spitzer Space Telescope’s 16th birthday, the Hubble Space Telescope team decided to put together a special present for their fellow “observing buddy.”

Hubble and Spitzer have observed many of the same astronomical objects over the years; and with Spitzer getting data from infrared, and Hubble getting data from visible, ultraviolet, and some near-infrared, the two telescopes have helped uncover some of the mysteries of the universe.

Researchers Demonstrate The World’s First Quantum Radar

Posted by in categories: computing, encryption, quantum physics

Yes, we know that sometimes it feels like they just tack the word quantum on new technology and call it a day like we are all living in the Marvel Cinematic Universe. Nevertheless, quantum technology is very real and is just as exciting. Our better understanding of the quantum world and handle on the principals will help us improve everything from computing to encryption.

Robotic Neck Brace Dramatically Improves Functions of ALS Patients

Posted by in categories: bioengineering, biotech/medical, life extension, robotics/AI, wearables

New York, NY—August 12, 2019—A novel neck brace, which supports the neck during its natural motion, was designed by Columbia engineers. This is the first device shown to dramatically assist patients suffering from Amyotrophic Lateral Sclerosis (ALS) in holding their heads and actively supporting them during range of motion. This advance would result in improved quality of life for patients, not only in improving eye contact during conversation, but also in facilitating the use of eyes as a joystick to control movements on a computer, much as scientist Stephen Hawkins famously did.


A team of engineers and neurologists led by Sunil Agrawal, professor of mechanical engineering and of rehabilitation and regenerative medicine, designed a comfortable and wearable robotic neck brace that incorporates both sensors and actuators to adjust the head posture, restoring roughly 70% of the active range of motion of the human head. Using simultaneous measurement of the motion with sensors on the neck brace and surface electromyography (EMG) of the neck muscles, it also becomes a new diagnostic tool for impaired motion of the head-neck. Their pilot study was published August 7 in the Annals of Clinical and Translational Neurology.
