Scientists have developed a new robot that can 'mimic' the two-handed movements of care-workers as they dress an individual.

Secrets of photosynthesis have been discovered at atomic level, shedding important new light on this plant super-power that greened the earth more than a billion years ago.

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.

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.

Collaborative work has developed a cell culture system that differentiates human pluripotent stem cells to amniotic ectoderm and surface ectoderm based on cell density.

A new study finds younger adults look and feel older on stressful days -- but only on days when they also feel they have relatively less control over their own lives.

A new neuroimaging study reveals how the brain gets to the creative flow state.

When certain species of wild birds and primates discover new ways of finding food in the wild, it can serve to measure their flexibility and intelligence. In the largest experimental study ever conducted on this topic, researchers have shown that foraging problems requiring overcoming obstacles, such as removing the lid off a container of food, are the only predictors of brain size and innovative behavior in the wild.

Researchers estimate the cost of removing 1 ton of CO2 from the air in the year 2050 to be between 230 and 540 US dollars to remove 1 ton. This is twice as high as previous estimates. The researchers compared the potential costs of three technologies that are already in use. From today's perspective, none of these technologies has clear advantages over the others in terms of potential costs. All three technologies should therefore be further developed, say the researchers.

Researchers have developed a new way to control and manipulate optical signals by embedding a liquid crystal layer into waveguides created with direct laser writing. The new devices enable electro-optical control of polarization, which could open new possibilities for chip-based devices and complex photonic circuits based on femtosecond-written waveguides.

You'd probably walk past a chiton without even seeing it. These creatures often look like nothing more than another speck of seaweed on the crusty intertidal rocks. But it sees you. At least, if it's one of the species with eyes dotting its platemail shell.

A team of researchers has discovered a noninvasive, low-cost test to detect oral cancer, monitor precancerous lesions and determine when a biopsy is warranted.

A new cell phone app developed by physician-scientists, which uses artificial intelligence (AI) to accurately diagnose ear infections, or acute otitis media (AOM), could help decrease unnecessary antibiotic use in young children, according to new research.

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.

Geologists determined the original orientation of many of the Mars bedrock samples collected by the Perseverance rover. The findings can give scientists clues to the conditions in which the rocks originally formed.

A comprehensive study of high-temperature superconducting magnets confirms they meet requirements for an economic, compact fusion power plant.

A vaccine against Zika virus is safe and effective when administered both before and during pregnancy, according to new research.

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.

A team has collected dozens of samples from across southeastern Colorado, and their results could help to answer an enduring mystery: What made Colorado's High Plains so high?

In a discovery that opens the door to a less invasive way of treating some serious disorders before birth, UC San Francisco scientists have found that delivering medicine through amniotic fluid is as effective as delivering it to the fetal brain via cerebrospinal fluid. The experiment was done in mice with a genetic disorder called Angelman syndrome.
