UrduA cohort study of patients with atrial fibrillation (AF) and low risk for stroke has found that the use of early rhythm control therapy was associated with a lower risk of cardiovascular death, ischemic stroke, hospitalization for heart failure, or myocardial infarction compared to rate control therapy. The findings are published in Annals of Internal Medicine.

The physics of walking is simpler than we thought
The physics of walking for multi-legged animals and robots is simpler than previously thought. That is the finding described by a team of roboticists, physicists and biologists in the Sept. 5 issue of the Proceedings of the National Academy of Sciences, in a paper titled “Walking is like slithering: a unifying, data-driven view of locomotion.”

Stem Cell-Gene Therapy Shows Promise in ALS Safety Trial
Cedars-Sinai investigators have developed an investigational therapy using support cells and a protective protein that can be delivered past the blood-brain barrier. This combined stem cell and gene therapy can potentially protect diseased motor neurons in the spinal cord of patients with amyotrophic lateral sclerosis, a fatal neurological disorder known as ALS or Lou Gehrig’s disease.
Study calls for change in guidance about eating fish during pregnancy
A woman’s mercury level during pregnancy is unlikely to have an adverse effect on the development of the child provided that the mother eats fish, according to a new University of Bristol-led study.
City-based soda pop taxes don’t effectively reduce sugar consumption
As taxes on sugar-sweetened beverages continue to pop up across the U.S. and abroad, public health experts laud their effect on lowering purchases of the calorie-heavy drinks and encouraging healthier habits. But new research from the University of Georgia suggests many soda taxes might actually not be making much of an impact at all when it comes to improving diets and reducing sugar intake.
Lessons learned from COVID-19 mitigation measures
Researchers analyzed how the expectation of a vaccine influences optimal lockdown measures during a pandemic.
How to protect yourself against summer urinary tract infections
Summertime means lots of opportunities for fun in the sun. But this year’s high temperatures also bring an increased risk of dehydration that can cause urinary tract infections (UTIs), said Maude Carmel, M.D., Associate Professor of Urology at UT Southwestern Medical Center. These common infections are marked by a burning sensation or pain with urination, increased urinary frequency, urinary urgency, and blood in the urine (a condition called hematuria).
Mothers with diabetes can have a healthy breastfeeding experience
Breastfeeding offers a wealth of benefits both for mothers and their babies. Although diabetes can complicate the process, it does not prevent mothers from giving their babies this wonderful start to life, according to UT Southwestern endocrinologist Maria Ramos-Roman, M.D., Associate Professor of Internal Medicine.

Uncovering the Atomic Mechanism Underpinning Heat Transport in Thermoelectric Materials
To better understand how thermoelectric devices convert thermal energy into electricity at the atomic scale, researchers used neutrons to study single crystals of tin sulfide and tin selenide. The results revealed a strong correlation between changes in the structure at certain temperatures and the frequency of atomic vibrations (phonons). This allowed the researchers to identify temperatures ideal for energy conversion and provided basic scientific knowledge for designing new thermoelectric materials.
How historical precedents impeded recognition of airborne COVID-19 transmission
Millions of people have died of coronavirus infection since 2020 because influential institutions took too long to recognize that it is primarily airborne, and a new University of Colorado Boulder-led historical analysis sheds light on the delay.

‘Diamond rain’ on giant icy planets could be more common than previously thought
A new study has found that “diamond rain,” a long-hypothesized exotic type of precipitation on ice giant planets, could be more common than previously thought. In an earlier experiment, researchers mimicked the extreme temperatures and pressures found deep inside ice giants Neptune and Uranus and, for the first time, observed diamond rain as it formed.
Water-based gel to be tested as dressing for diabetic wounds
In early experiments, Jianjun Guan and his team found that after applying a single dose of their wound dressing into wounds in young diabetic mice, the wounds completely closed at day 14. Wounds that were treated only with the hydrogel or were untreated were reduced to roughly half of their original size.
Climate anxiety an important driver for climate action – new study

Two vaccine doses provide only limited and short-lived protection against SARS-CoV-2 infection with the Omicron variant. A study publishing September 1st in the open-access journal PLOS Medicine by Mie Agermose Gram at Statens Serum Institut, Copenhagen, Denmark, and colleagues suggests that a third COVID-19 vaccine dose increased the level and duration of protection against Omicron infection and hospitalization.
