Influenza or a cold? A new technology can help you
Smart gadgets in the home might soon be able to tell you what’s wrong with you. But the technology is good news for a lot of other things too.
Microresonators made of germanium. These might have a bigger impact on your future than you might think.
« Influenza or a cold? A new technology can help you
Newswise — Some people do such smart and difficult things that it’s hard to see what in the world they might have to do with you and me, so we just shrug them off. But that’s often the wrong response.
What if you had a simple gadget at home that could tell you why you’re feeling so lousy?
Our microresonator is about 100 times better than what was available before for the longwave infrared spectrum.
What if this gadget could within short order check whether you have COVID or the flu – or maybe it would even pick up that you have diabetes without knowing it? The device could figure all this out without you having to go to a doctor or a laboratory.
Stores the light better
This technology could become a reality within a few years, and electrical engineers are some of people who make it possible to create such gadgets, which contain a key component called the whispering gallery mode microresonator.
New technology is providing better optical sensors, which are important for electronics, including devices that analyse chemicals using light.
“We’ve built the lowest loss whispering gallery mode microresonator out there for the longwave infrared spectrum. Because the longwave infrared spectrum provides definitive information about chemicals, it provides new possibility for sensing applications,” says Dingding Ren, a researcher at the Norwegian University of Science and Technology’s (NTNU) Department of Electronic Systems.
We’ll talk more about what a microresonator is later in the article. But first back to Ren. He and his colleagues have developed a new whispering gallery mode microresonator – which can store light for certain wavelengths much longer in the resonance.
“Our microresonator is about 100 times better than what was available before for the longwave infrared spectrum,” says Ren.
“It can retain the light 100 times longer than previous versions, which amplifies the optical field inside and makes nonlinear processes much easier, such as frequency comb generation,” he said.
Opens up great opportunities
Storing light waves in the infrared part of the light spectrum more effectively is good news for several types of new technologies, especially for particle sensing and spectroscopic chemical identification that analyse a gas/fluid sample to check for viruses and bacteria and other nasties you might have.
The new microresonator means that scientists can develop broadband frequency combs in the longwave infrared spectrum using these devices. And just what might those be?
Frequency combs are laser lights whose spectrum consists of a series of discrete, equally spaced frequency lines. These can be found various places, such as in your GPS, in atomic clocks and in fibre optic equipment used in telephones and computers. The technology also opens the door to analysing several chemicals at once, if a broadband frequency comb is available at the longwave infrared spectrum.
“The technology is still in its initial stage when it comes to measurements in this the longwave infrared spectrum of light. But our improvement gives us the possibility to identify several different chemicals in real time in the near future,” says Ren.
This kind of spectroscopic machine already exists, like something called a Fourier-transform infrared interferometer, but they are so big and so expensive that only hospitals and big budget institutions can afford them. Other, slightly simpler machines might be able to analyse a few chemicals, but not many at once – unlike what the new technology could make possible.
Ren has worked closely with Professor David Burghoff and his colleagues at the University of Notre Dame in the USA.
“The competition is fierce in this field,” says Ren.
The new microresonator is made using the element germanium. The material may sound exotic, but was used in the world’s first transistor as early as 1947, before silicon took over that market.
We can compare the microresonator to what happens with the sound in the whispering gallery in St. Paul’s Cathedral in London.
Today, germanium is frequently used in optical lenses in sensors and infrared cameras, and it is consequently neither particularly rare nor expensive. These are also advantages when theory is going to be brought to the market.
What are microresonators anyway?
Microresonators, which a type of optical cavities, can store high optical field inside a very small volume. They can be made into a trace or disk geometry, but they usually are at a microscale dimension, similar to the thickness of a hair. Light travels inside the microresonator in circles, so the optical field gets amplified.
“We can compare the microresonator to what happens with the sound in the whispering gallery in St. Paul’s Cathedral in London,” says Ren.
This elliptical gallery has produced a famous phenomenon. You can whisper at one end of it and people at the other end of the room can hear you, even though they wouldn’t normally be to able hear you at that distance. The sound waves are amplified by the shape of the room and the walls, which is how light waves behave in the microresonator. You can read the research article if you want to try to understand this phenomenon better. The link can be found at the bottom of the article.
Funded by Fripro money
Ren is financing the research through a Fripro project grant from the Research Council of Norway, which lasts for three years. Money from Fripro is dedicated to basic research.
“We promised that we would develop a better microresonator, and we’ve succeeded,” Ren said. The research group delivered on its promise.
Stunning work
Bjørn-Ove Fimland and Astrid Aksnes, both professors in NTNU’s Department of Electronic Systems, have provided advice along the way.
“Ren has done excellent work, which is supported by the fact that he’s had an article published in Nature Communications,” says Aksnes.
The fact that we can now measure in the longwave IR range (8-14 µm, or micrometres) of the light spectrum opens up many possibilities in relation to use in imaging and detection, environmental monitoring and biomedical applications, says Aksnes.
“Many molecules have fundamental vibrational bands in the mid-wave IR range (2-20 µm), the so-called ‘molecular fingerprint region’. By measuring in this wave range, we achieve higher sensitivity,” she says.

Truth Initiative and NAACP Expand Partnership to Advance Health Equity and Increase Access to Proven Quit Resources
Health Equity
When we talk about health equity, we’re really talking about who gets the chance to live a longer, healthier life — and who has been systematically denied that chance. Tobacco and nicotine addiction remain a clear example of that imbalance, especially in Black communities and other historically marginalized groups.
That’s why Truth Initiative and the NAACP are expanding their partnership to increase access to proven quit support and to reframe nicotine cessation as something bigger than an individual choice. Their new phase of collaboration launches the Breath of Freedom Movement, powered by Truth Initiative and the NAACP — a community-centered effort that combines civil rights leadership with public health expertise.
A movement rooted in community and accountability
The Breath of Freedom Movement builds on the work of the Breath of Freedom coalition, an alliance led by Truth Initiative across Black-led organizations. The coalition’s mission has been to reclaim the narrative around tobacco use, confront the ways the industry has shaped that narrative, and connect people to support that respects culture, history, and lived experience.
This expansion arrives at a critical moment. According to the press release, approximately 45,000 Black Americans die each year from smoking-related illness. The burden is not accidental — it has been driven in large part by decades of targeted marketing of menthol cigarettes and other flavored tobacco products.
The release highlights another stark disparity: more than 80% of Black smokers use menthol cigarettes, compared with 43% of adult smokers overall. Menthol products are often described as easier to start and harder to quit, which makes access to culturally relevant cessation resources not just helpful, but essential.
Launching at the NAACP National Convention in Chicago
The Breath of Freedom Movement will officially launch at the NAACP National Convention, taking place July 18–22, 2026, in Chicago. The convention theme, “We, The People,” commemorates the nation’s 250th anniversary and marks 100 years since Chicago first hosted the NAACP conference in 1926.
As part of the convention programming, Truth Initiative will debut the Rise Together EXperience: Culture, Community, and Nicotine-Free Lives — an immersive mobile exhibit designed to explore how tobacco use and industry marketing tactics have impacted Black, Hispanic, and LGBTQ+ communities. The exhibit is also meant to connect people to quit support in a way that feels accessible and grounded in real community conversations.
What the expanded partnership will do
Truth Initiative and the NAACP say this partnership is designed to move beyond awareness and into action — action that’s rooted in community spaces where trust already exists. The expanded collaboration will focus on:
- Hosting culturally relevant presentations, community forums, workshops, and healing-centered discussions about the health consequences of smoking, vaping, and nicotine addiction, with a focus on disproportionate impacts.
- Advancing the Breath of Freedom mission by reframing nicotine cessation as an act of liberation and resistance to the tobacco industry’s exploitation of Black communities.
- Co-developing and distributing culturally relevant public health content, including toolkits, digital resources, and community-informed cessation materials.
- Promoting awareness of and access to proven quit resources — including Truth Initiative’s EX Program — in partnership with Black-led organizations, faith-based groups, LGBTQ+ advocates, and other culturally aligned stakeholders.
- Strengthening local, regional, and national outreach strategies that elevate community voices and mobilize grassroots support for nicotine prevention and cessation.
In the release, Dr. Chris T. Pernell, Director of the NAACP Center of Health Equity, underscored that health equity requires more than information — it requires accountability and community-rooted action that connects people with tools for healing and freedom from addiction.
Quitting as liberation — not just willpower
One of the most important shifts in this work is the language: quitting isn’t framed as a moral test or a matter of “just trying harder.” Instead, it’s positioned as a supported process — and as a way for communities to push back against systems that have profited from addiction.
As Dr. Dartis noted in the announcement, the tobacco industry has targeted Black communities for generations with products and marketing designed to drive nicotine addiction. The expanded partnership aims to meet people where they are — in trusted spaces, through meaningful conversations, and with resources that recognize culture and lived experience.
Bridging public health data and lived experience
The press release also notes that Dr. Dartis will be featured in an upcoming NAACP docuseries focused on bridging the gap between public health data and the lived experiences of Black men in America. The project will explore the systems, relationships, and environments that shape health outcomes, while highlighting resilience and calling for accountability from the systems meant to serve communities.
How to get free quit support
If you or someone you care about is ready to quit smoking, vaping, or other nicotine products, free support is available through Truth Initiative’s EX Program.

Local resources (Arizona)
If you’re in Arizona and want additional, local support, consider these options:
- Arizona Smokers’ Helpline (ASHLine): Call 1-800-55-66-222 or visit https://www.azdhs.gov/ashline/ for free quit coaching and support for Arizona residents.
- Arizona 2-1-1: Dial 2-1-1 (or visit 211arizona.org) to get connected to local health services, community programs, and support resources.
- Primary care clinics and community health centers: If you have a regular doctor or use a community clinic, ask about quit plans and nicotine replacement options. Many clinics can help you build a step-by-step approach and connect you to additional programs.
The takeaway
The Breath of Freedom Movement is a reminder that nicotine addiction doesn’t exist in a vacuum. It’s connected to policy, marketing, access to care, and the long history of unequal health outcomes in the United States. By combining community leadership with proven quit resources, Truth Initiative and the NAACP are working to ensure that communities most impacted by tobacco-related harm have the support they need to heal, quit, and thrive.

Three new studies shared this week at the Society of NeuroInterventional Surgery (SNIS) 23rd Annual Meeting deliver a clear message: stroke care in the U.S. is improving, but those gains are not reaching everyone equally. Researchers found persistent disparities tied to race, geography, and socioeconomic status—factors that can shape whether a patient receives advanced treatment, how quickly they reach specialized care, and ultimately, whether they survive.
Stroke remains one of the nation’s leading causes of death and long-term disability. In recent years, breakthroughs in emergency response systems and minimally invasive procedures have expanded what’s possible in the critical first hours after a stroke. But the latest findings suggest that access to those life-saving advances still depends too heavily on who you are and where you live.
Study 1: Treatment gaps widen as strokes get more severe
The first study, “Racial Disparities in Endovascular Thrombectomy Widen with Stroke Severity: A National Inpatient Sample Analysis,” examined more than 325,000 acute ischemic stroke patients treated at U.S. teaching hospitals between 2018 and 2022.
The focus was endovascular thrombectomy (EVT), a minimally invasive procedure in which specialists remove a clot from a blocked artery in the brain. EVT can be a game-changer for eligible patients—but researchers found Black patients were less likely than white patients to receive it across all levels of stroke severity.
What stood out most: the disparity grew as stroke severity increased. At a National Institutes of Health Stroke Scale (NIHSS) score of 20, the predicted probability of receiving EVT was:
- 33% for white men
- 32% for white women
- 28% for Black men
- 26% for Black women
Co-first author Muhammed Amir Essibayi, MD, MSc, FRCP, noted that timely access becomes even more critical as severity rises—yet the treatment gap becomes more pronounced. The study also highlighted an intersectional pattern, with Black women consistently least likely to receive EVT.
Study 2: Hemorrhagic stroke deaths are falling—but disparities persist
The second study, “Reducing Inequalities in Stroke Events-Hemorrhagic Disparities (RISE-HD): A 10-year Statewide Analysis of Social Determinants of Mortality in Hemorrhagic Stroke,” analyzed more than 120,000 patients hospitalized with hemorrhagic stroke in Florida between 2013 and 2024.
There was good news: mortality rates declined significantly over the decade, suggesting real progress in stroke systems and hospital care.
But after adjusting for age, sex, and comorbidities, disparities remained. Black patients had higher odds of in-hospital mortality than white patients. Higher mortality was also associated with:
- Living in rural areas
- Having Medicaid or other non-commercial insurance
Researchers also found regional differences across Florida, pointing to uneven access to specialized stroke care.
Primary author Natália Vasconcellos, MD, MSc, emphasized that improving outcomes for everyone will require addressing barriers to specialized stroke systems—especially in underserved communities.
Study 3: The “Stroke Belt” has two different access problems
The third study, “Dual Pathways to Hemorrhagic Stroke Mortality Across the U.S. Stroke Belt: Rural Neurointerventional Isolation and Urban Structural Vulnerability,” looked at hemorrhagic stroke mortality across 433 counties in the “Stroke Belt,” a region long associated with higher stroke rates and worse outcomes.
Researchers compared factors linked to mortality in rural versus urban counties, including:
- Distance to the nearest Comprehensive Stroke Center
- Community-level socioeconomic disadvantage
- Racial and economic segregation
- HIV burden
They found the drivers of mortality differed sharply by setting:
- In rural counties, longer travel times to Comprehensive Stroke Centers were more strongly associated with higher mortality.
- In urban counties, racialized economic segregation and HIV burden were more strongly associated with poorer outcomes—even when specialized care was geographically closer.
Dylan Yates, a medical student at Tulane University School of Medicine, summarized the takeaway: the neurointerventional access gap in the Stroke Belt is “not one problem, it is two.” Solutions need to match the reality on the ground—strengthening transfer networks and specialty connections in rural areas, while addressing structural disadvantage and underinvestment in urban communities.
What to watch for: where the system can improve
Across all three studies, the common thread is that medical innovation alone doesn’t guarantee equitable outcomes. Researchers pointed toward targeted interventions that could help close the gap, including:
- More consistent, equitable treatment pathways for advanced stroke procedures like EVT
- Stronger stroke transfer networks to reduce delays—especially in rural regions
- Expanded access to specialty stroke care and Comprehensive Stroke Centers
- Community-level investment and structural reforms in underserved urban neighborhoods
For patients and families, these findings also reinforce the importance of recognizing stroke symptoms quickly and calling 911 immediately. Time is brain—yet the system must ensure that “time” and “access” don’t vary based on race, ZIP code, or insurance status.Source: Society of NeuroInterventional Surgery (SNIS), July
