Chinese researchers have developed a wireless, paper-thin patch that attaches to an organ to create a highway for drug delivery.

To solve an important problem in drug delivery, a research team that includes Beihang University and Peking University developed an electronic patch that acts like a band-aid for organs.

Traditional drug delivery systems send a vague package through the body that requires higher doses than necessary and might harm organs in the process of trying to find their destination. Large-molecule drugs, or biopharmaceuticals based on proteins, face an even greater challenge as the cell membrane often blocks these drugs, according to CGTN.

Thin film solar cells can be integrated into unexpected surfaces, such as building facades, windows, or the growing floating solar market. Thin film’s flexibility opens doors to new applications and helps overcome some of the barriers that have long limited the adoption of solar energy.

A lot of the interest in thin film solar technologies is coming from one company, based right in the heart of the UK: Power Roll. The County Durham-based firm has spent years exploring how to make thin, flexible solar cells that can be applied almost anywhere and has recently been hitting major milestones in commercialising the technology in an effort to get it out across the world.

Solar Power Portal sat down with Power Roll CEO Neil Spann to explore how thin film solar could deliver the government’s promised “rooftop revolution” and how Power Roll’s unique manufacturing process can make solar power a cheap reality worldwide.

Laser-cooled atomic gases, gases of atoms chilled to temperatures around absolute zero using laser technologies, have proved to be versatile physical platforms to study and control quantum phenomena. When these atomic gases interact with light inside an optical cavity (i.e., a structure designed to trap and enhance light), they can give rise to effects that can be leveraged to realize quantum sensing or simulate complex quantum systems.

Using loaded in optical cavities, physicists have observed various intriguing effects, including self-organization phase transitions, characterized by the spontaneous arrangement of the gas atoms into ordered patterns, lasing and the preservation of quantum coherence. Generally, however, these effects are only observed for short times, as new atoms need to be reloaded in the cavity for them to be produced again.

Researchers at JILA, a joint research institute of the University of Colorado-Boulder and the National Institute of Standards and Technology, recently demonstrated continuous lasing that lasted hours using laser-cooled strontium-88 (88 Sr) atoms loaded into a ring (i.e., circular) . Their paper, published in Nature Physics, could open new possibilities for the development of ultra-quiet lasers, as well as quantum computers and sensing technologies.

A team of evolutionary scientists, dermatologists and wildlife specialists affiliated with several institutions in Japan, Kenya and France has found that human skin wounds take nearly three times as long to heal as they do in other primates. In their study, published in the journal Proceedings of the Royal Society B: Biological Sciences, the group conducted experiments involving skin healing speed in humans and several other primates.

Prior research and anecdotal evidence suggest that other animals recover from skin wounds faster than humans. In this new effort, the research team sought to measure such differences.

The experiments involved comparing skin wounds in humans—courtesy of volunteers at a hospital undergoing skin tumor removal—and several primates. Wound healing pace in chimpanzees was measured by studying chimps housed at a sanctuary who endured skin wounds periodically due to fighting between males.
