  • Different kinds of mindfulness may fight different kinds of anxiety

    A group of people meditate while in a yoga class.

    New research lays out a new approach to understanding the relationship between mindfulness and anxiety.

    If you’re anxious about work, finances, the state of the world or anything else, you might try a moment of mindfulness. Paying close attention to the present moment without judgment—the basic idea behind all mindfulness techniques—can help calm anxiety and improve focus, says Resh Gupta, a postdoctoral research associate with the Mindfulness Science and Practice research cluster at Washington University in St. Louis.

    “A lot of research has shown that mindfulness can reduce anxiety symptoms,” she says.

    The calming power of mindfulness is well-known to people who have made the practice a part of their daily lives. Still, experts continue to investigate how it works and which types of mindfulness might be most useful for different types of anxiety, ranging from fleeting bouts of worry to more chronic, clinical anxiety disorders.

    “We all experience anxiety, but it can manifest in many different ways,” Gupta says. “It’s a tough problem to pin down.”

    Instead of taking a one-size-fits-all approach, Gupta and coauthors propose that different kinds of mindfulness practices might be helpful for different varieties of anxiety. The proposed framework should ultimately help us understand how to match anxiety sufferers with more precise treatments, Gupta says.

    The research appears in Neuroscience and Biobehavioral Reviews.

    Todd Braver, a professor in human values and moral development and a professor of psychological and brain sciences, is a coauthor of the paper. The other coauthor is Wendy Heller, a professor of psychology at the University of Illinois Urbana-Champaign.

    “There is a growing recognition that these practices can be incredibly useful in enhancing psychological well-being,” Braver says. “But we still do not fully understand the mechanisms of action by which mindfulness can produce beneficial effects. That’s where the scientific research can be so valuable, by helping us more precisely identify why and how certain practices are effective.”

    Gupta, Braver, and Heller suggest that mindfulness combats anxiety by improving a mental process called cognitive control.

    “Cognitive control is the ability to regulate your thoughts and your actions in a way that helps you achieve your goals,” Gupta says. “For example, if you know you have to go to the grocery store right after work, you can keep that goal in mind during the workday and turn down an offer to do something else after work.”

    As Gupta explains, mindfulness and anxiety have opposite effects on cognitive control. People who are more mindful generally perform better on tasks requiring cognitive control. That observation is supported by neuroimaging studies, which have shown that mindfulness meditation can effectively modulate activity in brain regions that support cognitive control.

    On the other hand, anxiety can worsen cognitive control.

    “Worry occupies a lot of space in the brain’s working memory system,” Gupta says. “This is where your goals are stored.”

    This impairment in cognitive control can intensify worry symptoms, but using mindfulness to improve cognitive control can help interrupt the harmful cycle of worry.

    Depending on the type of anxiety people are experiencing, some approaches might work better than others, Gupta says. People who spend a lot of time worrying may especially benefit from a type of mindfulness meditation called focused attention.

    “Focused attention teaches you to choose an anchor, such as your breath or a sound,” she says. “You keep bringing your attention back to that anchor every time your mind wanders. Instead of focusing on the worry, you’re focusing on the present moment experience.”

    People who are hypervigilant and experiencing a lot of physical symptoms of anxiety—rapid heartbeat, sweaty palms, tightness in the chest—may do better with a different approach.

    “For this type of anxiety, a form of mindfulness meditation called open monitoring may be beneficial,” Gupta says. “Instead of focusing on one thing, such as the breath, you can observe all internal and external experiences from moment to moment in a non-reactive, non-judgmental way.”

    Braver is enthusiastic that recent research will help people gain a greater appreciation of the wide variety of practices that fall under the mindfulness umbrella.

    “People have different options they can choose from, so it becomes easier to find one that best fits your particular temperament, concerns or current situation,” he says.

    “It’s quite empowering to learn these types of practices, and to feel like we can be in charge of how we use them to improve our quality of life.”

  • Smart fabric uses sound to measure touch, pressure, and more

    A researcher wearing a blue glove holds a small black square of fabric that has thin glass fibers woven through it.

    Researchers have developed smart textiles that use acoustic waves instead of electronics to measure touch, pressure, and movement precisely.

    Imagine wearing a T-shirt that measures your breathing or gloves that translate your hand movements into commands for your computer.

    Researchers at ETH Zurich, led by Daniel Ahmed, professor of acoustic robotics for life sciences and health care, have laid the foundations for just such smart textiles.

    Unlike many previous developments in this area, which usually use electronics, the researchers rely on acoustic waves passed through glass fibers. This makes the measurements more precise and the textiles lighter, more breathable, and easier to wash.

    “They are also inexpensive because we use readily available materials, and the power consumption is very low,” says Ahmed.

    The researchers call their development SonoTextiles.

    “While research has already been conducted into smart textiles based on acoustics, we are the first to explore the use of glass fiber in combination with signals that use different frequencies,” explains Yingqiang Wang, the first author of the study.

    The researchers have woven glass fibers into the fabric at regular intervals. At one end of each glass fiber is a small transmitter that emits sound waves. The other end of each of the glass fibers is connected to a receiver that measures whether the waves have changed.

    Each transmitter works at a different frequency. This means it requires little computing power to determine which fiber the sound waves have changed on. Previous smart textiles often struggled with data overload and signal processing issues, since each sensor location had to be evaluated individually.

    “In the future, the data could be sent directly to a computer or smartphone in real time,” says Ahmed.

    When a glass fiber moves, the length of the acoustic waves passing through it changes, as they lose energy. In the case of a T-shirt, this can be caused by body movement or even breathing.

    “We used frequencies in the ultrasonic range, around 100 kilohertz—well beyond the range of human hearing, which is between 20 hertz and 20 kilohertz,” Wang emphasizes.

    The researchers have shown that their concept works in the lab. In the future, SonoTextiles could be used in a variety of ways: as a shirt or T-shirt, they could monitor the breathing of asthma patients and trigger an alarm in an emergency.

    In sports training and performance monitoring, athletes could receive real-time analysis of their movements, to optimize their performance and prevent injuries. The textiles also have potential for sign language: gloves with this technology could simultaneously translate hand movements into text or speech. They could also be used in virtual or augmented reality environments.

    “SonoTextiles could even measure a person’s posture and improve their quality of life as an assistive technology,” adds Chaochao Sun, who shares first authorship of the study. People who want to improve their posture could receive targeted feedback to correct poor posture. The textiles could also indicate when a wheelchair user needs to change position to prevent pressure ulcers.

    Although the everyday usability of SonoTextiles is potentially very high, Ahmed adds that there is still room for improvement in terms of practical application. Glass microfibers worked well as sound conductors in the lab, but they could potentially break in everyday use.

    “The beauty is that we can easily replace the glass fibers with metal. Sound also propagates effectively through metal,” explains Ahmed. “We would like to expand our research in this direction and also into other applications.”

    The researchers now want to make the system more robust and examine how the electronics can be better integrated into the textiles.

  • Listen: How dementia changes how people act

    A middle-aged man with a white beard looks off into the middle distance.

    In a new podcast episode, a neurologist digs into the “social brain” and how dementia affects how we act.

    When someone we know or love starts to develop psychological issues, we don’t often associate it with a form of dementia. However, this trait is one of the most common signs of frontotemporal dementia (FTD) —the most common neurodegenerative disease in people under the age of 65.

    In his new book, Mysteries of the Social Brain: Understanding Human Behavior Through Science (Routledge, 2025), Bruce Miller highlights his experiences observing people with FTD and what they have taught him about what he calls the “social brain.”

    Miller has been observing people with FTD for decades in the Memory and Aging Center at the University of San Francisco, where he is also professor of neurology and the founding director of the Global Brain Health Institute.

    In this episode of the Big Brains podcast, he shares key insights on how to keep our “social brain” healthy and how it can even unlock our creative potential:
