Low-cost solar-powered water filter removes lead, other contaminants
2021-03-31
A new invention that uses sunlight to drive water purification could help solve the problem of providing clean water off the grid.
The device resembles a large sponge that soaks up water but leaves contaminants - like lead, oil and pathogens - behind. To collect the purified water from the sponge, one simply places it in sunlight. The researchers described the device in a paper published this week in the journal Advanced Materials.
The inspiration for the device came from the pufferfish, a species that takes in water to swell its body when threatened, and then releases water when danger passes, said the device's co-inventor END ...
Even without a brain, Penn Engineering's metal-eating robots can search for food
2021-03-31
When it comes to powering mobile robots, batteries present a problematic paradox: the more energy they contain, the more they weigh, and thus the more energy the robot needs to move. Energy harvesters, like solar panels, might work for some applications, but they don't deliver power quickly or consistently enough for sustained travel.
James Pikul, assistant professor in Penn Engineering's Department of Mechanical Engineering and Applied Mechanics, is developing robot-powering technology that has the best of both worlds. His environmentally controlled voltage source, or ECVS, works like a battery, in that the energy is produced by repeatedly breaking ...
National study examines US mammography screening rates during COVID-19 pandemic
2021-03-31
In looking at the broader impact of the COVID-19 pandemic on health and wellbeing, public health experts are examining screening rates for cancer. A new study looking at U.S. mammography screening rates during the first five months of the pandemic found both a strong rebound in breast cancer screening rates and a concerning cumulative deficit in mammograms due to missed appointments, as well as uncovering disparities when looking at screening according to race.
The study was released this week in the Journal of the National Cancer Institute.
Conducted by investigators from the Breast Cancer Surveillance Coalition (BCSC), a federally-funded, national network of breast imaging registries, the study sought to quantify the impact of the COVID-19 ...
Crnic Institute discovery may explain high risk of leukemia in children with Down syndrome
2021-03-31
Denver, CO, March 31, 2020 - Children with Down syndrome are 20-times more likely to develop acute lymphocytic leukemia (ALL) and 150-times more likely to develop acute myeloid leukemia (AML) compared to their typical peers. According to a new study by researchers at the Linda Crnic Institute for Down Syndrome, the reason could be that children with Down syndrome are more likely to present with clonal hematopoiesis (CH), a process in which a blood stem cell acquires a genetic mutation that promotes replication.
The findings, published online by Blood Advances, add to a growing body of evidence, much of which has been established ...
Deep diamonds contain evidence of deep-Earth recycling processes
2021-03-31
Washington, DC-- Diamonds that formed deep in the Earth's mantle contain evidence of chemical reactions that occurred on the seafloor. Probing these gems can help geoscientists understand how material is exchanged between the planet's surface and its depths.
New work published in Science Advances confirms that serpentinite--a rock that forms from peridotite, the main rock type in Earth's mantle, when water penetrates cracks in the ocean floor--can carry surface water as far as 700 kilometers deep by plate tectonic processes.
"Nearly all tectonic plates that make up the seafloor eventually bend and slide down into ...
10,000-plus medical charts provides comparator for HIV prevention study in pregnant women
2021-03-31
PITTSBURGH --31 March 2021 - A detailed examination of more than 10,000 medical records at maternity clinics and hospitals in urban Malawi, South Africa, Uganda and Zimbabwe has yielded important insight about pregnancy and neonatal outcomes in these communities as well as the frequency with which different complications occur. The findings, which were published in PLOS ONE, include data not often available or reported in much of eastern and southern Africa.
The medical chart review was undertaken by researchers from the National Institutes of Health-funded Microbicide Trials Network ...
450-million-year-old sea creatures had a leg up on breathing
2021-03-31
A new study has found the first evidence of sophisticated breathing organs in 450-million-year-old sea creatures. Contrary to previous thought, trilobites were leg breathers, with structures resembling gills hanging off their thighs.
Trilobites were a group of marine animals with half-moon-like heads that resembled horseshoe crabs, and they were wildly successful in terms of evolution. Though they are now extinct, they survived for more than 250 million years -- longer than the dinosaurs.
Thanks to new technologies and an extremely rare set of fossils, scientists from UC Riverside can now show that trilobites breathed oxygen and explain how ...
Preventive medicine physician shortage continues to fall behind population needs in the US
2021-03-31
March 31, 2021 - The United States is facing a persistent and worsening shortage of physicians specializing in preventive medicine, reports a study in the Journal of Public Health Management and Practice. The journal is published in the Lippincott portfolio by Wolters Kluwer.
"The number of preventive medicine physicians is not likely to match population needs in the United States in the near term and beyond," according to the new research by Thomas Ricketts, Ph.D., MPH, and colleagues of University of North Carolina at Chapel Hill. The study appears ...
Study: Race made no difference in ICU Outcomes of COVID-19 patients
2021-03-31
DETROIT (March 31, 2021) - In a study that looked at racial differences in outcomes of COVID-19 patients admitted to the intensive care unit, researchers at Henry Ford Hospital in Detroit found that patients of color had a lower 28-day mortality than white patients.
Race, however, was not a factor in overall hospital mortality, length of stay in the ICU or in the rate of patients placed on mechanical ventilation, researchers said.
The findings, published in Critical Care Medicine, are believed to be one of the first in the United States to study racial differences and outcomes specific to patients hospitalized ...
Decades of hunting detects footprint of cosmic ray superaccelerators in our galaxy
2021-03-31
An enormous telescope complex in Tibet has captured the first evidence of ultrahigh-energy gamma rays spread across the Milky Way. The findings offer proof that undetected starry accelerators churn out cosmic rays, which have floated around our galaxy for millions of years. The research is to be published in the journal Physical Review Letters on Monday, April 5.
"We found 23 ultrahigh-energy cosmic gamma rays along the Milky Way," said Kazumasa Kawata, a coauthor from the University of Tokyo. "The highest energy among them amounts to a world record: nearly one petaelectron volt."
That's three ...
