Feeling stressed? Science finds a simple way to take back control

A tight work deadline, a clogged toilet, or a disagreement with a loved one can make an ordinary day feel overwhelming. When several of these small frustrations build up, stress can quickly escalate. But according to new research that includes scientists from Penn State, simply feeling more in control might help make those everyday challenges easier to handle.

The study found that on days when people felt they had greater control over their stressors, they were 62% more likely to take action — such as calling a plumber or addressing a difficult conversation — to solve the problem. This effect became even stronger with age. The results suggest that a person’s sense of control can serve as an important psychological resource that can be strengthened over time to help manage stress and improve health outcomes.

The findings were published in the journal Communications Psychology.

Small Boosts, Big Benefits

“This research shows that even small boosts in how much control people feel they have over everyday hassles make it more likely that those hassles actually get resolved,” said David Almeida, professor of human development and family studies at Penn State and senior author on the paper. “Learning to find and act on these pockets of control in daily life may not only reduce stress but also support long-term health and well-being.”

Previous work led by Almeida has shown that stress responses fluctuate over time and that even minor daily inconveniences can affect health when they accumulate. Actively resolving stressors — such as clearing up an argument — is a key part of processing stress and allows emotions to settle more quickly.

Measuring How Control Affects Stress

In this new study, the researchers wanted to know whether a sense of personal control — how much people feel they can influence their daily challenges — affects whether a stressor gets resolved. For instance, does believing you can fix a billing mistake make you more likely to call the company? The team also examined what influences that sense of control, including the type of stress, how often stressors occur, and socioeconomic conditions.

“If perceived stressor control promotes stress resolution, can we leverage that as a modifiable resource to influence stressor resolution and therefore our emotional health and well-being?” asked lead author Dakota Witzel, who was a postdoctoral scholar at the Center for Healthy Aging at Penn State during the time of the research and is now an assistant professor at South Dakota State University.

Tracking Daily Stress Over a Decade

The researchers analyzed data from more than 1,700 adults who took part in the National Study of Daily Experiences, part of the long-running Midlife in the United States Survey (MIDUS), a national study on health and well-being. For eight consecutive days, participants reported any daily stressors they experienced within the previous 24 hours and whether each stressor was resolved by the end of the day. Common sources of stress included interpersonal tensions (arguments or avoided arguments), home or work overload, and “network stress” — problems affecting friends or family that still caused distress for the participant.

Participants also rated how much control they felt over each stressor on a four-point scale (none, a little, some, or a lot of control). The same survey was repeated with these participants 10 years later to see whether the connection between perceived control and stress resolution changed with time.

Control Levels Fluctuate From Day to Day

Results showed that people’s sense of control can shift greatly from one day to the next. In other words, feeling in control is not a fixed personal trait — it’s a daily perception that varies depending on circumstances.

Across all ages, on days when people felt more in control than usual — for instance, feeling “some” control instead of “a little” — they were significantly more likely to resolve the stressor. This pattern held true regardless of the stressor’s type or intensity.

Interestingly, the connection grew stronger with age. Early in the study, participants who felt a higher-than-usual level of control were 61% more likely to resolve their stressors that day. A decade later, the same boost in perceived control raised that likelihood to 65%.

“This work also begins to show that as we get older, not only do we have more control but that control helps us get better at handling stress,” Witzel said.

Building a Sense of Control

The findings suggest that perceived control can serve as a key tool for reducing daily stress.

“It’s encouraging news that daily control isn’t fixed. It can be strengthened through practical strategies such as setting priorities or reframing what’s within reach,” Almeida said. “We need to figure out how we can create the context and setting to allow people to feel more control.”

Practical ways to build control include focusing on what’s within reach, breaking large challenges into smaller steps, and using time blocking or lists to track progress. These small wins can create momentum and reduce stress. Asking for help or delegating tasks can also boost the sense of support and control. Ending each day with a short reflection may help people prepare mentally for the next day.

What’s Next for the Research

The team plans to keep studying how perceived control interacts with long-term or chronic stress.

“In this study, we’re talking about daily stressors, the minor inconveniences that occur throughout the day, but there’s also chronic stress where people are continually impacted by stressors again and again,” Witzel said. “Exploring the idea of whether resolution can be a mechanism that decreases the effect of chronic stress is an interesting area to explore.”

Scientists create LED light that kills cancer cells without harming healthy ones

Scientists have developed a promising cancer therapy that uses LED light and ultra-thin flakes of tin to eliminate cancer cells while protecting healthy tissue. Unlike traditional chemotherapy and other invasive treatments, this new method avoids the painful side effects patients often endure.

The breakthrough comes from a partnership between The University of Texas at Austin and the University of Porto in Portugal, made possible through the UT Austin Portugal Program. The collaboration aims to make light-based cancer therapies more accessible and affordable. Current versions of these treatments rely on expensive materials, specialized lab setups, and powerful lasers that can sometimes damage surrounding tissue. By switching to LEDs and introducing tin-based “SnOx nanoflakes” (“Sn” is the chemical symbol for tin), the researchers have created a safer and potentially low-cost alternative.

LED Light and Nanoflakes Team Up Against Cancer

“Our goal was to create a treatment that is not only effective but also safe and accessible,” said Jean Anne Incorvia, a professor in the Cockrell School of Engineering’s Chandra Family Department of Electrical and Computer Engineering and one of the leaders on the project. “With the combination of LED light and SnOx nanoflakes, we’ve developed a method to precisely target cancer cells while leaving healthy cells untouched.”

In a recent study published in ACS Nano, the approach proved highly effective against both colorectal and skin cancer cells. After only 30 minutes of exposure, the LED-driven treatment destroyed up to 92% of skin cancer cells and 50% of colorectal cancer cells, while leaving healthy human skin cells unharmed. The results highlight the therapy’s precision and safety.

A Safer Alternative to Conventional Cancer Treatments

Cancer remains the second-leading cause of death worldwide, and many existing treatments come with severe side effects. Scientists across the globe are exploring new methods to make therapies safer and more targeted. One of the most promising is near-infrared photothermal therapy, which uses light to heat and destroy cancer cells without the need for surgery or toxic drugs. This principle forms the foundation of the UT Austin-Portugal team’s research.

Having shown strong early results, the researchers are now focused on understanding how light and heat interact in the process and on testing other materials that might enhance the treatment. They also plan to design practical medical devices that can deliver the therapy directly to patients.

Bringing Light-Based Cancer Care to Patients

“Our ultimate goal is to make this technology available to patients everywhere, especially places where access to specialized equipment is limited, with fewer side effects and lower cost,” said Artur Pinto, a researcher at the Faculty of Engineering of the University of Porto and lead researcher of the project in Portugal. “For skin cancers in particular, we envision that one day, treatment could move from the hospital to the patient’s home. A portable device could be placed on the skin after surgery to irradiate and destroy any remaining cancer cells, reducing the risk of recurrence.”

Incorvia and Pinto first teamed up through the UT Austin Portugal Program in 2021. Since then, they have exchanged visits between Texas and Portugal and combined their expertise to explore how two-dimensional materials can be used to advance cancer therapies.

Expanding the Research Frontier

Building on their success, the team recently received additional funding through the UT Austin Portugal Program to create an implant for breast cancer patients using the same LED and nanoflake technology. Their continued collaboration could pave the way for more personalized, affordable, and pain-free cancer treatments in the near future.

Other co-authors of the article are: Ph.D. student Hui-Ping Chang (led development of the nanoflakes) and undergraduate student Eva Nance of The University of Texas at Austin; Filipa A.L.S. Silva (performed biological characterization), Susana G. Santos (supervised the work) and professor Fernão Magalhães (contributed to securing funding) of Faculty of Engineering of the University of Porto; and José R. Fernandes of the University of Trás-os-Montes and Alto Douro, who developed the LED systems.

The UT Austin Portugal Program is a long-standing science and technology partnership between UT and the Portuguese Foundation of Science and Technology (FCT). Portugal has similar partnerships with two other U.S. universities — the Massachusetts Institute of Technology and Carnegie Mellon University — and its 17-year collaboration with UT was recently renewed for another five years.

Tom Blyth Apologises For ‘Embarrassing’ Cillian Murphy Blunder

Tom Blyth has apologised after a video went viral in which he referred to the Irish actor Cillian Murphy as a “British icon”.

Last month, the Hunger Games star took part in a video interview with British Vogue at a Burberry London Fashion Week event, during which he was asked to name one “British icon” he’d like to see collaborate with the brand in the future.

“Ooh I mean, Cillian Murphy,” Tom responded. “Let’s say Cillian.”

Asked by an Irish reporter for The Standard about his blunder, Tom said: “Firstly, I’m so sorry to you and your people. I’ve nothing but respect for the Irish and I love Cillian Murphy. I was so embarrassed.”

Tom added: “I was so jet-lagged that I didn’t listen to the question properly and I just blurted it out.”

He then remarked: “Oh my God, Cillian Murphy is never going to want to work with me. I genuinely was knackered and just not listening properly.

“I’ve learned my lesson. Next time, critically hearing is an important thing.”

After the interview was first shared online, HuffPost UK contacted Tom Blyth’s team for comment, but did not receive a response.

Cillian has repeatedly had to make clear his Irish identity in the past, including while promoting the 2010 thriller Inception, when a reporter referred to him and his co-star Tom Hardy as “British actors”.

“Nah, I’m Irish,” he replied at the time, and when the interviewer in question suggested this meant he was, in fact, British, Cillian insisted: “No, no, no, no. There’s a big difference.”
