More than 80% of stroke survivors experience walking difficulty, significantly impacting their daily lives, independence, and overall quality of life. Now, new research pushes forward the bounds of stroke recovery with a unique robotic hip exoskeleton, designed as a training tool to improve walking function. This invites the possibility of new therapies that are more accessible and easier to translate from practice to daily life compared to current rehabilitation methods. Read more ›

Quantum sensor technology promises even more precise measurements of physical quantities. A team has now compared the signals of up to 91 quantum sensors with each other and thus successfully eliminated the noise caused by interactions with the environment. Correlation spectroscopy can be used to increase the precision of sensor networks. Read more ›

Childhood lead exposure, primarily from paint and water, is a significant health concern in the United States, but a new study has identified a surprising additional source of lead exposure that may disproportionately harm children: firearms. A team found an association between household firearm ownership and elevated lead levels in children's blood in 44 states, even when controlling for other major lead exposure sources. Read more ›

An inexpensive, cavity-fighting liquid called silver diamine fluoride (SDF) works as well as dental sealants to keep tooth decay at bay in a school cavity prevention and treatment program, according to a new study. The study, which followed more than 4,000 elementary school students for four years, shows that SDF is an effective alternative to sealants, and can increase access to dental care while reducing costs.

Falling from the tip of a brush suspended in mid-air, an ink droplet touches a painted surface and blossoms into a masterpiece of ever-changing beauty. It weaves a tapestry of intricate, evolving patterns. Some of them resemble branching snowflakes, thunderbolts or neurons, whispering the unique expression of the artist's vision. Read more ›

Galvanized steel containers and surfaces are used for harvested produce because of their durability, strength and lower cost compared to stainless steel. However, bacteria residing in storage containers can cause corrosion. The new coating will reduce corrosion by at least 70 percent, researchers say. Read more ›

Astronomers can use supercomputers to simulate the formation of galaxies from the Big Bang 13.8 billion years ago to the present day. But there are a number of sources of error. An international research team has spent a hundred million computer hours over eight years trying to correct these. Read more ›

Are genetic factors underlying children's language development linked to later-life outcomes? In a genome-wide analysis, an international research team found genetic associations between children's early vocabulary size and later-life ADHD, literacy, and general cognition. These associations changed dynamically across the first three years of life. Both producing more words in infancy and understanding fewer words in toddlerhood were associated with a higher risk of ADHD. Read more ›

New findings reveal that the body undergoes significant, systematic changes across multiple organs during prolonged periods of fasting. The results demonstrate evidence of health benefits beyond weight loss, but also show that any potentially health-altering changes appear to occur only after three days without food. Read more ›
