Managing complex medication schedules could soon become as simple as taking a single capsule each day. Engineers at the University of California San Diego have developed a capsule that can be packed with multiple medications and release them at designated times throughout the day.

The advance, published in Matter, could help improve and by eliminating the need for patients to remember taking multiple drugs or doses at various times each day. It could potentially reduce the risk of missed doses or accidental overdoses.

“We want to simplify medication management with a single that is smart enough to deliver the right drug at the right dose at the right time,” said study first author Amal Abbas, who recently earned her Ph.D. in chemical engineering at the UC San Diego Jacobs School of Engineering. She spearheaded this work with Joseph Wang, a professor in the Aiiso Yufeng Li Family Department of Chemical and Nano Engineering at UC San Diego.

A new study led by a pair of researchers at the University of Massachusetts Amherst turns long-held conventional wisdom about a certain type of polymer on its head, greatly expanding understanding of how some of biochemistry’s fundamental forces work. The study, released recently in Nature Communications, opens the door for new biomedical research running the gamut from analyzing and identifying proteins and carbohydrates to drug delivery.

The work involves a kind of polymer made up of neutral polyzwitterions. Because they have a neutral electrical charge, polyzwitterions are not expected to respond to an electric field. However, the team found not only that certain neutral polyzwitterions behave as if they were charged, but also that the electric field surrounding polyzwitterions, once thought to be uniform, varies in strength.

“My interest is in the proteins and , which are the building blocks for protein, inside our body’s cells,” says Yeseul Lee, lead author and graduate student in polymer science and engineering at UMass Amherst.

A research team has developed the world’s first next-generation betavoltaic cell by directly connecting a radioactive isotope electrode to a perovskite absorber layer. By embedding carbon-14-based quantum dots into the electrode and enhancing the perovskite absorber layer’s crystallinity, the team achieved both stable power output and high energy conversion efficiency.

The work is published in the journal Chemical Communications. The team was led by Professor Su-Il In of the Department of Energy Science & Engineering at DGIST.

The newly developed technology offers a stable, long-term power supply without the need for recharging, making it a promising next-generation energy solution for fields requiring long-term power autonomy, such as , , and military applications.

Interdisciplinary teams across the Quantum Systems Accelerator (QSA) are using innovative approaches to push the boundaries of superconducting qubit technology, bridging the gap between today’s NISQ (Noisy Intermediate-Scale Quantum) systems and future fault-tolerant systems capable of impactful science applications.

QSA is one of the five United States Department of Energy National Quantum Information Science (QIS) Research Centers, bringing together leading pioneers in (QIS) and engineering across 15 partner institutions.

A superconducting is made from such as aluminum or niobium, which exhibit quantum effects when cooled to very low temperatures (typically around 20 millikelvins, or −273.13° C). Numerous technology companies and research teams across universities and national laboratories are leveraging for prototype scientific computing in this rapidly growing field.

The quantum black hole with (almost) no equations by Professor Gerard ‘t Hooft.

How to reconcile Einstein’s theory of General Relativity with Quantum Mechanics is a notorious problem. Special relativity, on the other hand, was united completely with quantum mechanics when the Standard Model, including Higgs mechanism, was formulated as a relativistic quantum field theory.

Since Stephen Hawking shed new light on quantum mechanical effects in black holes, it was hoped that black holes may be used to obtain a more complete picture of Nature’s laws in that domain, but he arrived at claims that are difficult to use in this respect. Was he right? What happens with information sent into a black hole?

The discussion is not over; in this lecture it is shown that a mild conical singularity at the black hole horizon may be inevitable, while it doubles the temperature of quantum radiation emitted by a black hole, we illustrate the situation with only few equations.

About the Higgs Lecture.

The Faculty of Natural, Mathematical & Engineering Sciences is delighted to present the Annual Higgs Lecture. The inaugural Annual Higgs Lecture was delivered in December 2012 by its name bearer, Professor Peter Higgs, who returned to King’s after graduating in 1950 with a first-class honours degree in Physics, and who famously predicted the Higgs Boson particle.

A new “atlas” developed by researchers at Duke University School of Medicine, University of Tennessee Health Science Center, and the University of Pittsburgh will increase precision in measuring changes in brain structure and make it easier to share results for scientists working to understand neurological diseases such as Alzheimer’s disease.

The tool, the Duke Mouse Brain Atlas, combines microscopic resolution, three-dimensional images from three different techniques to create a detailed map of the entire brain, from large structures down to and circuits.

“This is the first truly three-dimensional, stereotaxic of the mouse brain,” said G. Allan Johnson, Ph.D., Charles E. Putman University Distinguished Professor of Radiology at Duke. He is also professor in the Department of Physics and the Department of Biomedical Engineering.

As global demand for electric vehicles and renewable energy storage surges, so does the need for affordable and sustainable battery technologies. A new study has introduced an innovative solution that could impact electrochemical energy storage technologies.

The research is published in the journal Advanced Functional Materials. The work was led by researchers from the Department of Materials Science and NanoEngineering at Rice University, along with collaborators from Baylor University and the Indian Institute of Science Education and Research Thiruvananthapuram.

Using an oil and gas industry’s byproduct, the team worked with uniquely shaped —tiny cones and discs—with a pure graphitic structure. These unusual forms produced via scalable pyrolysis of hydrocarbons could help address a long-standing challenge for anodes in battery research: how to store energy with elements like sodium and potassium, which are far cheaper and more widely available than lithium.

Lightweight lithium metal is a heavy-hitting critical mineral, serving as the key ingredient in the rechargeable batteries that power phones, laptops, electric vehicles and more. As ubiquitous as lithium is in modern technology, extracting the metal is complex and expensive. A new method, developed by researchers at Penn State and recently granted patent rights, enables high-efficiency lithium extraction—in minutes, not hours—using low temperatures and simple water-based leaching.

“Lithium powers the technologies that define our modern lives—from smartphones to electric vehicles—and has applications in grid energy storage, ceramics, glass, lubricants, and even medical and nuclear technologies,” said Mohammad Rezaee, the Centennial Career Development Professor in Mining Engineering at Penn State, who led the team that published their approach in Chemical Engineering Journal.

“But its extraction must also be environmentally responsible. Our research shows that we can extract lithium, and other , more efficiently while drastically reducing energy use, greenhouse gas emissions and waste that’s difficult to manage or dispose of.”
