Living tissue can heal itself from many injuries, but giving similar abilities to artificial systems, such as robots, has been extremely challenging. Now, researchers reporting in ACS' Nano Letters have developed small, swimming robots that can magnetically heal themselves on-the-fly after breaking into two or three pieces. The strategy could someday be used to make hardier devices for environmental or industrial clean up, the researchers say. Watch a video of the self-healing swimmers here.
Many children of low-income families across the country do not have access to quality health care. Lack of health care can have a domino effect, affecting educational outcomes in the classroom.
School-based telehealth could offer a sustainable and effective solution, according to a new report in the Journal for Nurse Practitioners by Kathryn King Cristaldi, M.D., the medical director of the school-based telehealth program, and Kelli Garber, the lead advanced practice provider and clinical integration specialist for the program.
Family-centered prevention programs that foster protective caregiving can buffer the negative effects of racial discrimination on young Black people, according to a study published by University of Georgia researchers.
The largest flightless bird ever to live weighed in up to 600kg and had a whopping head about half a metre long - but its brain was squeezed for space.
Dromornis stirtoni, the largest of the 'mihirungs' (an Aboriginal word for 'giant bird'), stood up to 3m high and had a cranium wider and higher than it was long due to a powerful big beak, leading Australian palaeontologists to look inside its brain space to see how it worked.
VANCOUVER, Wash. - Most people rely on family members to help them learn how to open a bank account, find a job or create a budget, but that's often not an option for youth in foster care, according to a recent study in Child & Family Social Work.
"Foster kids have distinctive challenges," said Amy Salazar, lead author on the study and an assistant professor at Washington State University Vancouver. "They need more support in several areas, and financial capability is one of them, especially when they're transitioning out of the foster care system and into adulthood."
Extremely hot and dry conditions that currently put parts of the UK in the most severe danger of wildfires once a century could happen every other year in a few decades' time due to climate change, new research has revealed.
A study, led by the University of Reading, predicting how the danger of wildfires will increase in future showed that parts of eastern and southern England may be at the very highest danger level on nearly four days per year on average by 2080 with high emissions, compared to once every 50-100 years currently.
The invisibility of dads who lose access to their children because of concerns about child neglect or their ability to provide safe care comes under the spotlight in new research.
A research partnership between the University of East Anglia and Lancaster University provides new evidence ('Up Against It': Understanding Fathers' Repeat Appearance in Local Authority Care Proceedings) about fathers' involvement in care and recurrent care proceedings in England.
"Based on field experiments with increased carbon dioxide concentration, artificial warming, and modified water supply, scientists understand quite well how future climate change will affect grassland vegetation. Such knowledge is largely missing for effects that already occurred in the last century," says Hans Schnyder, Professor of Grassland at the TUM.
umans are remarkably adaptable, and our ancestors have survived challenges like the changing climate in the past. Now, research is providing insight into how people who lived over 5,000 years ago managed to adapt.
Have you ever wondered why you are able to hear a sentence and understand its meaning - given that the same words in a different order would have an entirely different meaning? New research involving neuroimaging and A.I., describes the complex network within the brain that comprehends the meaning of a spoken sentence.
A new study co-authored by a Tulane University geoscientist shows that human efforts to tame the Mississippi River may have had an unintended positive effect: more rapid transport of carbon to the ocean.
Boulder, Colo., USA: When geobiology graduate student Katie Maloney trekked into the mountains of Canada's remote Yukon territory, she was hoping to find microscopic fossils of early life. Even with detailed field plans, the odds of finding just the right rocks were low. Far from leaving empty-handed, though, she hiked back out with some of the most significant fossils for the time period.
Researchers have succeeded in revealing the arsenal used by protozoans of the genus Leishmania in human cells to make leishmaniasis more severe, especially in cases of the mucocutaneous variety of the disease, which can cause deformations in patients. The discovery points the way to a search for novel treatments for the disease as well as casting light on a key mechanism involved in other diseases.
SAN ANTONIO (March 23, 2021) -- More than half of all health care workers worldwide are experiencing burnout that, if not addressed, could cause many to leave their fields in favor of less-stressful occupations or choose early retirement. And the COVID-19 pandemic has only made it worse.
That's the warning of a surgeon from The University of Texas Health Science Center at San Antonio in a letter and a call for global action published March 22 in the Lancet journal EClinicalMedicine.
There are 12 essential attributes that explain why commercial carbon capture and sequestration projects succeed or fail in the U.S., University of California San Diego researchers say in a recent study published in Environmental Research Letters.
