New tests can detect tiny but toxic particles of coal ash in soil

Eurekalert - Jul 22 2021 - 00:07
Duke University scientists have developed tests sensitive enough to detect and measure microscopic particles of coal ash in soil, even at concentrations so low and sizes so small that other tests would likely miss them. The four new tests complement tests previously developed at Duke to detect coal ash contamination in water and larger particles of coal ash in soil.

Perfecting collagen production in osteogenesis imperfecta

Eurekalert - Jul 22 2021 - 00:07
Mesenchymal stem cells are the origin for osteoblasts, but MSC transplantation has not resulted in long-term success as a treatment option for brittle bone disease. Hematopoietic stem cells usually give rise to blood cells and osteoclasts, but researchers hypothesized that they could give rise to osteoblasts too. By replacing osteoblasts, they offer a potential therapeutic opportunity that is not dependent on a specific mutation but simply on a mutation being present, which gives patients hope.

Big data-derived tool facilitates closer monitoring of recovery from natural disasters

Eurekalert - Jul 22 2021 - 00:07
By analyzing peoples' visitation patterns to essential establishments like pharmacies, religious centers and grocery stores during Hurricane Harvey, researchers at Texas A&M University have developed a framework to assess the recovery of communities after natural disasters in near real time. They said the information gleaned from their analysis would help federal agencies allocate resources equitably among communities ailing from a disaster.

'Good cholesterol' may protect liver

Eurekalert - Jul 22 2021 - 00:07
The body's so-called good cholesterol may be even better than we realize. New research from Washington University School of Medicine in St. Louis suggests that one type of high-density lipoprotein (HDL) has a previously unknown role in protecting the liver from injury. This HDL protects the liver by blocking inflammatory signals produced by common gut bacteria.

Early-life social connections influence gene expression, stress resilience

Eurekalert - Jul 22 2021 - 00:07
Having friends may not only be good for the health of your social life, but also for your actual health--if you're a hyena, that is. Strong social connections and greater maternal care early in life can influence molecular markers related to gene expression in DNA and future stress response, suggests a new University of Colorado Boulder study of spotted hyenas in the wild.

Study: Young workers now value respect over 'fun' perks in the workplace

Eurekalert - Jul 22 2021 - 00:07
Millennials, often referred to as the "job-hopping generation," represent a group of young workers who once grabbed the national spotlight with their publicized demands for "fun" work perks, such as happy hours. However, researchers at the Novak Leadership Institute at the University of Missouri and Kansas State University discovered today's young workers -- ages 21-34 -- represent a life-stage shift toward placing more value on having respectful communication in the workplace over trendy work perks.

Cattle losing adaptations to environment, MU researchers find

Eurekalert - Jul 22 2021 - 00:07
In a new PLOS Genetics study, researchers have uncovered evidence showing that cattle are losing important environmental adaptations, losses the researchers attribute to a lack of genetic information available to farmers. After examining genetic material stretching back to the 1960s, they identified specific DNA variations associated with adaptations that could one day be used to create DNA tests for cattle -- tests that could tell farmers whether their cattle are suited for one environment or another.

Investigational magnetic device shrinks glioblastoma in first-in-world human test

Eurekalert - Jul 22 2021 - 00:07
Houston Methodist Neurological Institute researchers from the department of neurosurgery shrunk a deadly glioblastoma tumor by more than a third using a helmet generating a noninvasive oscillating magnetic field that the patient wore on his head while administering the therapy in his own home. The 53-year-old patient died from an unrelated injury about a month into the treatment, but during that short time, 31% of the tumor mass disappeared. The autopsy of his brain confirmed the rapid response to the treatment.

During COVID-19, nurses face significant burnout risks, reports American Journal of Nursing

Eurekalert - Jul 22 2021 - 00:07
Early in the COVID-19 pandemic, more than 40 percent of nurses and other health care workers had risks associated with an increased likelihood of burnout, reports a survey study in the August issue of the American Journal of Nursing (AJN). The journal is published in the Lippincott portfolio by Wolters Kluwer.

'Wrapping' anodes in 3D carbon nanosheets: The next big thing in li-ion battery technology

Eurekalert - Jul 22 2021 - 00:07
The lithium-ion battery is the future of sustainable energy technology, but drastic volume fluctuations in their anodes related to enhanced battery capacity raises a safety concern. Recently, researchers from the Republic of Korea have found that embedding manganese selenide anodes in a 3D carbon nanosheet matrix is an innovative, simple, and low-cost means of reducing drastic volume expansion while improving the energy density of these batteries.

Soft skin patch could provide early warning for strokes, heart attacks

Eurekalert - Jul 22 2021 - 00:07
UC San Diego engineers developed a soft, stretchy ultrasound patch that can be worn on the skin to monitor blood flow through vessels deep inside the body. Such a device can make it easier to detect cardiovascular problems, like blockages in the arteries that could lead to strokes or heart attacks.

The anatomy of a planet

Eurekalert - Jul 22 2021 - 00:07
Researchers at ETH Zurich working together with an international team have been able to use seismic data to look inside Mars for the first time. They measured the crust, mantle and core and narrowed down their composition. The three resulting articles are being published together as a cover story in the journal Science.

InSight mission: Mars unveiled

Eurekalert - Jul 22 2021 - 00:07
Using information obtained from around a dozen earthquakes detected on Mars by the Very Broad Band SEIS seismometer, developed in France, the international team of NASA's InSight mission has unveiled the internal structure of Mars. The three papers published on July 23, provide, for the first time, an estimate of the size of the planet's core, the thickness of its crust and the structure of its mantle, based on the analysis of seismic waves reflected and modified by interfaces in its interior.
