Buzzing to rebuild broken bone

Healing broken bones could get easier with a device that provides both a scaffold for the bone to grow on and electrical stimulation to urge it forward, UConn engineers report. Although minor bone breaks usually heal on their own, large fractures with shattered or missing chunks of bone are more difficult to repair. A biocompatible, dissolving polymer device can mimic the body's natural electrical field and help the cells regenerate.

Life-hack: Rituals spell anxiety relief

UConn Assistant Professor of Anthropology Dimitris Xygalatas studies rituals and how they impact our health. In new research published in Philosophical Transactions of the Royal Society, Xygalatas and collaborators from Masaryk University, Czech Republic, including former UConn student Martin Lang, examine the important roles rituals play in reducing our anxiety levels.

Nanoparticle for overcoming leukemia treatment resistance

One of the largest problems with cancer treatment is the development of resistance to anticancer therapies. A research team found that repurposing a commonly used chemotherapy drug using a nanoparticle developed at UConn was more effective than both a solution of the pure drug and other available treatments.

UConn study examines how Americans are coping with COVID-19 stress

Almost overnight, the rapid emergence of the COVID-19 pandemic in the United States and subsequent state and federal prevention measures dramatically altered daily behavior. A unique early study by researchers from the University of Connecticut provides the first snapshot of the immediate impact of COVID-19 on Americans' stress levels, coping strategies, and adherence to public health guidelines.

Gestures heard as well as seen

Gesturing with the hands while speaking is a common human behavior, but no one knows why we do it. Now, a group of UConn researchers reports in the May 11 issue of PNAS that gesturing adds emphasis to speech--but not in the way researchers had thought.

Mismanagment, not tampering, at root of supply problems for Ugandan farmers

For years, speculation about the poor quality of vital agricultural supplies in the African nation of Uganda has focused on questions of deliberate tampering with products -- adding rocks to bags of seed in order to charge more money for the heavier product, for instance. But in a recent publication, two UConn researchers found no evidence of deliberate adulteration -- but plenty of proof that mismanagement and inadequate infrastructure pose a significant problem for Ugandan farmers.

Exploring the school-age social, emotional, and behavioral health landscape

Through a four-year federally funded project, UConn researchers looked at school districts across the country to better understand how social, emotional, and behavioral health screening tools are being employed, and what factors influence their use.

Popular gyms undermining health with tanning beds, UConn researcher says

Popular gym chains across the country capitalize on the broad desire to get healthy in the New Year with persuasive post-holiday marketing campaigns, but they're also undermining public health warnings about the dangers of indoor tanning, according to a new study from UConn researchers published today by the Journal of the American Medical Association (JAMA) Network Open.

Artificial skin could give superhuman perception

A new type of sensor could lead to artificial skin that someday helps burn victims 'feel' and safeguards the rest of us. UConn researchers wanted to create a sensor that can mimic the sensing properties of skin. Such a sensor would need to be able to detect pressure, temperature, and vibration. But why limit it? Perhaps it could do other things too.

A carcinogen at the gym

Gyms are places people go to get healthier. But nearly half the gyms in the U.S. contain a potentially addictive carcinogen -- tanning beds, report UConn researchers in the July 18 issue of JAMA Dermatology. Exercise reduces the risk of every cancer except melanoma. Tanning beds in gyms make tanning seem like part of a healthy lifestyle, undermine public health messaging and target a vulnerable population.

Strain improves performance of atomically thin semiconductor material

UConn materials scientists show conclusively for the first time that the properties of atomically thin materials can be mechanically manipulated to enhance their performance. The finding could lead to faster computer processors and more efficient optical sensors.

Republicans more persuasive than scientists on climate change

Regardless of political affiliation, people are more likely to believe facts about climate change when they come from Republicans speaking against what has become a partisan interest in this country, says a new UConn study.

Invasion of the body-snatching fungus

UConn researchers recently documented in Nature Scientific Reports a gory and fascinating relationship between periodical cicadas and a fungus that infects them, hijacks their behavior, and causes a scene straight out of a zombie movie.

Bacterial Fats, not dietary ones, may deserve the blame for heart disease

Heart disease and fatty clogs in the arteries go hand in hand. But new evidence suggests the fatty molecules might come not only from what you eat, but from the bacteria in your mouth, report UConn scientists in the 16 August issue of the Journal of Lipid Research. The research may explain why gum disease is associated with heart trouble.

UConn doctors using 3-D models to practice delicate surgery

FARMINGTON, Conn. (AP) — Doctors at the University of Connecticut are using 3-D printing technology to help them practice some delicate brain surgery. Since 2012, physicians have been using a procedure to treat strokes called a mechanical thrombectomy, guiding a catheter through a patient’s arteries and vessels into the brain to remove blood clots. Medical […]

The veins in your brain don't all act the same

Certain blood vessels in the brainstem constrict when blood vessels elsewhere in the body would dilate. And that contrary behavior is what keeps us breathing, according to a new paper by UConn researchers published May 8 in eLife.

Chili peppers and marijuana calm the gut

You wouldn't think chili peppers and marijuana have much in common. But when eaten, both interact with the same receptor in our stomachs, according to a paper by UConn researchers published in the April 24 issue of the journal Proceedings of the National Academy of Sciences. The research could lead to new therapies for diabetes and colitis, and opens up intriguing questions about the relationship between the immune system, the gut and the brain.

Know thy enemy: Kill MRSA with tailored chemistry

UConn medicinal chemists have developed experimental antibiotics that kill MRSA, a common and often deadly bacteria that causes skin, lung, and heart infections. The success is due to their strategy, which found a weakness and exploited it in a way the bacteria should have trouble countering, the researchers report in the December 22 issue of Cell Chemical Biology.
