(Press-News.org) Designed a high-performance double-spoke superconducting cavity.
The research team implemented comprehensive electromagnetic and mechanical optimizations on the double-spoke superconducting cavity, achieving three key improvements: reduction of peak electric field during normal operation, suppression of multipacting effects, and enhanced manufacturability. A dedicated Buffered Chemical Polishing tooling system was developed for double-spoke superconducting cavities with complex structures, ensuring uniform acid etching and achieving high Q-values (Q > 3.4×10¹⁰ @ Eₐcc = 9 MV/m).
Developed a high-performance cryomodule
The double-spoke cavity cryomodule employs carbon fiber tie rods to suspend the superconducting cavities within the cryostat, effectively reducing heat leakage while allowing convenient positional adjustment of the cavity in cryogenic environments.
Development of the Cooling Procedure for Superconducting Cavity Cryogenic System
Based on the significant correlation between cooling rate and Q-value observed during vertical testing of double-spoke superconducting cavities, an optimized cryogenic cooling protocol was developed with precisely controlled cooling rates, to maximize Q-value preservation.

Study helps pinpoint areas where microplastics will accumulate
2025-06-05
The accumulation of microplastics in the environment, and within our bodies, is an increasingly worrisome issue. But predicting where these ubiquitous particles will accumulate, and therefore where remediation efforts should be focused, has been difficult because of the many factors that contribute to their dispersal and deposition.
New research from MIT shows that one key factor in determining where microparticles are likely to build up has to do with the presence of biofilms. These thin, sticky biopolymer layers are shed by microorganisms and can accumulate ...
NRG Oncology study shows the addition of regional nodal irradiation does not decrease rates of invasive breast cancer recurrence in patients whose axillary nodes convert from positive to negative foll
2025-06-05
Recent results from the NRG-NSABP B-51/RTOG 1304 clinical study showed that the addition of regional nodal irradiation (RNI) does not decrease the rates of invasive breast cancer recurrence in patients whose positive axillary nodes at presentation convert to negative following neoadjuvant chemotherapy. These results were recently published in the New England Journal of Medicine.
The study enrolled 1,641 patients stratified by type of surgery (mastectomy, lumpectomy), hormone receptor status (ER-positive and/or PgR-positive; ER- and PgR-negative), HER2 status, adjuvant chemotherapy use, and pathologic complete response (pCR) in the breast, then randomized to RNI vs. ...
Cancer treatments should be licensed for all ages, oncologists say
2025-06-05
Recent advances have resulted in highly effective “tissue-agnostic” drugs that treat cancers based on their molecular markers rather than their tissue of origin, but very few of these drugs are approved for use in children. In an opinion paper publishing June 5 in the Cell Press journal Trends in Cancer, oncologists call for “ag(e)nostic” cancer treatments: drugs that are both tissue agnostic and approved for cancer patients of all ages.
“Cancer treatment in children is a huge unmet need. These drugs are extremely effective, and we want to see children have access to them,” says senior author Razelle ...
US self-reported race and ethnicity are poor proxies of genetic ancestry
2025-06-05
Genetic ancestry is much more complicated than how people report their race and ethnicity. New research, using data from the National Institutes of Health’s (NIH) All of Us Research Program, finds that people who identify as being from the same race or ethnic group can have a wide range of genetic differences. The findings are reported June 5 in the Cell Press journal the American Journal of Human Genetics.
As doctors and researchers learn more about how genetic variants influence the incidence and course of human diseases, the study of genetic ancestry has become increasingly important. This research is driving the field of precision medicine, ...
Living towers of worms observed in nature
2025-06-05
Nematodes are the most abundant animal on earth, but when times get tough, these tiny worms have a hard time moving up and out. So, they play to the strength of their clade. If food runs out and competition turns fierce, they slither towards their numerous kin. They climb onto each other and over one another until their bodies forge a living tower that twists skyward where they might hitch a ride on a passing animal to greener and roomier pastures.
At least that’s what scientists assumed. For decades, these worm structures ...
New AI transforms radiology with speed, accuracy never seen before
2025-06-05
CHICAGO --- A first-of-its-kind generative AI system, developed in-house at Northwestern Medicine, is revolutionizing radiology — boosting productivity, identifying life-threatening conditions in milliseconds and offering a breakthrough solution to the global radiologist shortage, a large new study finds.
The findings will be published on Thursday (June 5) in JAMA Network Open.
“This is, to my knowledge, the first use of AI that demonstrably improves productivity, especially in health care. Even in other fields, I haven’t seen anything close to a 40% boost,” said senior author Dr. Mozziyar Etemadi, an assistant professor of anesthesiology ...
Brain mechanisms that distinguish imagination from reality discovered
2025-06-05
Areas of the brain that help a person differentiate between what is real and what is imaginary have been uncovered in a new study led by UCL researchers.
The research, published in Neuron, found that a region in the brain known as the fusiform gyrus – located behind one’s temples, on the underside of the brain’s temporal lobe – is involved in helping the brain to determine whether what we see is from the external world or generated by our imagination.
The researchers hope that their findings will increase understanding ...
Glucagon-like peptide-1 receptor agonists and risk of neovascular age-related macular degeneration
2025-06-05
About The Study: In this cohort study, the use of glucagon-like peptide-1 receptor agonists (GLP-1 RAs) among patients with diabetes was associated with a 2-fold higher risk of incident neovascular age-related macular degeneration development than among similar patients with diabetes who did not receive a GLP-1 RA. Further research is needed to elucidate the exact pathophysiological mechanisms involved and to understand the trade-offs between the benefits and risks of GLP-1 RAs.

BMI, physical activity, and subsequent neoplasm risk among childhood cancer survivors
2025-06-05
About The Study: Among childhood cancer survivors in this cohort study, obesity was associated with an increased risk for multiple subsequent neoplasm types, while higher physical activity was associated with reduced subsequent neoplasm risk. Lifestyle interventions should be considered in future subsequent neoplasm prevention research.

Chimpanzees can catch yawns from androids
2025-06-05
Chimpanzees (Pan troglodytes) can ‘catch’ yawns from an android imitating human facial expressions, according to new research from City St George’s, University of London.
The study, published in Scientific Reports, demonstrates that chimpanzees will both yawn and lie down in response to yawns made by an android, suggesting that it may act as a cue to rest rather than simply triggering an automatic response.
The findings appear to show contagious yawning due to an inanimate model for the first time, according to the authors, and the study also ...
