University of Missouri scientists are unlocking the secrets of halide perovskites—a material that’s poised to reshape our future by bringing us closer to a new age of energy-efficient optoelectronics.

Suchi Guha and Gavin King, two physics professors in Mizzou’s College of Arts and Science, are studying the material at the nanoscale: a place where objects are invisible to the naked eye. At this level, the extraordinary properties of halide perovskites come to life, thanks to the material’s unique structure of ultra-thin crystals—making it astonishingly efficient at converting sunlight into energy.

Think that are not only more affordable but also far more effective at powering homes. Or LED lights that burn brighter and last longer while consuming less energy.

Novel magnetic nanodiscs could provide a much less invasive way of stimulating parts of the brain, paving the way for stimulation therapies without implants or genetic modification, MIT researchers report.

The scientists envision that the tiny discs, which are about 250 nanometers across (about 1/500 the width of a human hair), would be injected directly into the desired location in the brain. From there, they could be activated at any time simply by applying a magnetic field outside the body. The new particles could quickly find applications in biomedical research, and eventually, after sufficient testing, might be applied to clinical uses.

The development of these nanoparticles is described in the journal Nature Nanotechnology, in a paper by Polina Anikeeva, a professor in MIT’s departments of Materials Science and Engineering and Brain and Cognitive Sciences, graduate student Ye Ji Kim, and 17 others at MIT and in Germany.

Bright, twisted light can be produced with technology similar to an Edison light bulb, researchers at the University of Michigan have shown. The finding adds nuance to fundamental physics while offering a new avenue for robotic vision systems and other applications for light that traces out a helix in space.

“It’s hard to generate enough brightness when producing twisted light with traditional ways like electron or photon luminescence,” said Jun Lu, an adjunct research investigator in chemical engineering at U-M and first author of the study on the cover of this week’s Science.

“We gradually noticed that we actually have a very old way to generate these photons—not relying on photon and electron excitations, but like the bulb Edison developed.”

Scientists have built an artificial motor capable of mimicking the natural mechanisms that power life. Just like the proteins in our muscles, which convert chemical energy into power to allow us to perform daily tasks, these tiny rotary motors use chemical energy to generate force, store energy, and perform tasks in a similar way.

The finding, from The University of Manchester and the University of Strasbourg and published in the journal Nature, provides new insights into the fundamental processes that drive life at the and could open doors for applications in medicine, , and nanotechnology.

“Biology uses chemically powered molecular machines for every , such as transporting chemicals around the cell, information processing or reproduction. By replicating nature at the nanoscale level, we can design entirely new materials with highly specific functions that don’t exist in the natural world. Building this outside of nature also gives us greater simplicity and control over its functions and uses,” said Professor David Leigh, lead researcher from The University of Manchester.

+ Decoding the secrets of DNA, CRISPR gene editing allows scientists to target specific genes linked to aging. By modifying these genes, researchers aim to prevent conditions that come with aging. Envision a future where genetic risks for age-related diseases are minimized through precise DNA editing.

It is possible to regenerate cells using stem cells, which can turn into a variety of types. In recent trials, stem cells showed promise in regenerating aged tissues like cartilage. Scientists hope to develop therapies that might slow down physical decline and maintain vitality longer by using this potential.

Nanobots could someday be the future of healthcare by targeting damaged cells directly as they move through your bloodstream. Researchers are currently exploring how nanobots might repair cellular damage and improve overall health, potentially reversing some age-related effects at the cellular level.

As the protective ends of chromosomes, telomeres shorten over time. When they become too short, cells stop functioning. In laboratory studies, researchers have extended the lifespan of animals by using telomere extension techniques. Though still experimental, this research could pave the way for human applications in slowing aging.

Bioengineers apply engineering and design principles to develop innovative solutions for biological and medical problems. Our researchers are creating tools and technologies to eliminate bottlenecks and reduce the time it takes for discoveries in stem cell research to reach the clinic as life-saving therapies. This includes everything from creating biodegradable scaffolds that can help stem cells Cells that have the ability to differentiate into multiple types of cells and make an unlimited number of copies of themselves. stem cells Cells that have the ability to differentiate into multiple types of cells and make an unlimited number of copies of themselves. regenerate damaged tissue to engineering materials that can make the immune-boosting effects of vaccines last longer.

Nanotechnology is the field of science focused on creating and manipulating structures and materials at the nanometer scale (one billionth of a meter). The application of nanotechnology in medicine recreates the natural scale of biological phenomena, enabling more precise and less invasive approaches for preventing, diagnosing and treating disease. Together with scientists from the California NanoSystems Institute at UCLA, our researchers are creating nanomaterials that enable targeted drug and gene delivery, more efficient production of cells for use as therapies and better models of human disease. Because nanotechnology-based methods enhance efficiency, require less material and use up less space, they can offer low cost, high-accuracy solutions for the study, diagnosis and treatment of disease.

By leveraging the combined strengths of nanotechnology and bioengineering, our researchers are accelerating the development of more effective and affordable stem cell-based therapies for a host of intractable medical conditions.
