Investigating the Individual Performances of Coupled Superconducting Transmon Qubits

The strong requirement for high-performing quantum computing led to intensive research on novel quantum platforms in the last decades. The circuital nature of Josephson-based quantum superconducting systems powerfully supports massive circuital freedom, which allowed for the implementation of a wide range of qubit designs, and an easy interface with the quantum processing unit. However, this unavoidably introduces a coupling with the environment, and thus to extra decoherence sources. Moreover, at the time of writing, control and readout protocols mainly use analogue microwave electronics, which limit the otherwise reasonable scalability in superconducting quantum circuits.

AI model could boost robot intelligence via object recognition

Stanford researchers have developed an innovative computer vision model that recognizes the real-world functions of objects, potentially allowing autonomous robots to select and use tools more effectively.

In the field of AI known as computer vision, researchers have successfully trained models that can identify objects in . It is a skill critical to a future of robots able to navigate the world autonomously. But is only a first step. AI also must understand the function of the parts of an object—to know a spout from a handle, or the blade of a bread knife from that of a butter knife.

Computer vision experts call such utility overlaps “functional correspondence.” It is one of the most difficult challenges in computer vision. But now, in a paper that will be presented at the International Conference on Computer Vision (ICCV 2025), Stanford scholars will debut a new AI model that can not only recognize various parts of an object and discern their real-world purposes but also map those at pixel-by-pixel granularity between objects.

Scientists create a novel hydrogel for unclonable security tags

Encryption technologies are vital in today’s digital landscape to protect sensitive information from hackers and prevent fraud. While cutting-edge encryption has been developed for data, sophisticated protection for physical objects such as high-value products, access cards and documents has lagged behind until now.

Scientists have now developed a new hydrogel that acts as an unclonable physical tag. The work is published in the journal Advanced Materials.

Physical items are easily copied or faked because their built-in security tags are often weak or simple to clone. To solve this security gap, a team of researchers from China first mixed two chemicals together: polypyrrole, which conducts electricity; and polystyrene sulfonate, a flexible polymer. The result was a soft, conductive, jelly-like substance.

Brainstem hub for stopping pain signals from reaching the brain

Acute or short-lived pain, despite its bad reputation, is usually a lifesaver. It acts as a transient negative sensory experience that helps us avoid danger. Touch a hot stove, stub a toe, or bonk your head on a low branch, and the nervous system cues up an “Ow!” Over time, the sting fades, the wound heals, but the lesson sticks.

Chronic pain is different; the alarm keeps blaring long after the fire is out, and then the pain itself becomes the problem. Nearly 50 million people in the United States live with chronic pain, an invisible and often untreatable condition that can linger for decades. “It’s not just an injury that won’t heal,” says a neuroscientist, “it’s a brain input that’s become sensitized and hyperactive, and determining how to quiet that input could lead to better treatments.”

Now, research has identified a key to regulating long-term pain states: a group of cells called Y1 receptor (Y1R)-expressing neurons in the brainstem’s lateral parabrachial nucleus (lPBN). These neurons are activated during enduring pain states, but they also integrate information about hunger, fear and thirst, allowing for pain signals to be modulated by other brain circuits signaling more urgent needs.

Christian Maugee — PhD Candidate, University Of Florida — From Patient To Genetics Research Pioneer

From patient to genetics research pioneer — christian maugee — phd candidate, university of florida.

Christian Maugee is a PhD Candidate at the University of Florida, in Genetics and Genomics (http://www.vulpelab.net/graduate-and-undergrad-students.html where his research explores how gene expression differs in the hearts of individuals with Friedrich’s Ataxia (FA), a rare, progressive neurodegenerative disease. His work could lead to new insights into the cardiac complications that can be associated with FA and how to potential treat them better.

Christian’s dissertation work is focused on identifying gene modulators of the transcriptional phenotype of FA in human induced pluripotent stem cells differentiated into cardiomyocytes (hPSC-CMs). He accomplishes this through use of a novel method: Perturb-seq — a CRISPR screen coupled with single cell RNA sequencing (scRNA-seq) readout.

Christian is driven by much more than academic curiosity, as he brings a unique and deeply human perspective to his work as someone living with FA. He doesn’t just study the challenges faced by those with disabilities; he lives them. His work is not only informed by data and theory, but by resilience, authenticity, and a commitment to making research more inclusive and impactful.

In the lab, Christian loves mentoring, and outside of the lab he loves fundraising and raising awareness for FA, mainly through FARA (https://www.curefa.org/) and MDA (https://www.mda.org/disease/friedreic…).

A hidden “backup heater” that helps burn fat and boost metabolism

Scientists at Washington University School of Medicine in St. Louis have uncovered a new way that brown fat, a type of fat that burns energy, can boost the body’s metabolism. This process allows cells to consume more fuel and generate heat, improving overall metabolic health. Conducted in mice, the research points to new possibilities for using brown fat to address metabolic conditions such as insulin resistance and obesity.

The findings were published Sept. 17 in Nature.

Brown fat is unique because it turns energy (calories) from food into heat. Unlike white fat, which stores energy, or muscle, which uses it immediately, brown fat helps keep the body warm in cold environments. Exposure to cold can increase the amount of brown fat, and scientists have long suggested that activating it could support weight loss by increasing calorie burning.
