Nearly a decade ago, global news outlets reported vast ice melt in the Arctic as sapphire lakes glimmered across the previously frozen Greenland Ice Sheet, one of the most important contributors to sea-level rise. Now researchers have revealed the long-term impact of that extreme melt.
Durham, NC - A phase 2 clinical trial whose results were released today in STEM CELLS Translational Medicine might point to a way to overcome bronchopulmonary dysplasia (BPD), a major cause of death in preterm infants. The study, conducted by researchers at Samsung Medical Center, Sungkyunkwan University and Asan Medical Center Children's Hospital in Seoul, evaluates the effectiveness of treating these infants by transplanting umbilical cord blood-derived mesenchymal stem cells (UCB-MSCs) directly into their tracheas.
Newly published research contained in the Special Issue of the Journal of Marketing features fourteen global author teams focused on the topic of Better Marketing for a Better World. Edited by Rajesh Chandy (London Business School), Gita Johar (Columbia University), Christine Moorman (Duke University), and John Roberts (University of New South Wales), this Special Issue brings together wide-ranging research to assess, illuminate, and debate whether, when, and how marketing contributes to a better world.
Recent growth in the number of healthcare workers providing home care for Medicare patients is "small and inadequate" compared with the increasing demand in an aging America, a new study suggests.
To have hope of keeping up, Medicare likely will need to reconsider how it compensates providers for home care, the researchers say.
Nearly three-quarters of Earth's land had been transformed by humans by 10,000BC, but new research shows it largely wasn't at the expense of the natural world.
A study involving University of Queensland researchers combined global maps of population and land use over the past 12,000 years with current biodiversity data, demonstrating the effective environmental stewardship of Indigenous and traditional peoples.
UQ's Professor James Watson said the findings challenged the modern assumption that human 'development' inevitably led to environmental destruction.
Unless you've studied chemistry in college, it's unlikely you've come across the name aziridine. An organic compound with the molecular formula, C2H4NH, aziridines are well-known among medicinal chemists, who make use of the compound to prepare pharmaceutical drugs such as Mitomycin C, a chemotherapeutic agent known for its anti-tumor activity. Specifically, aziridines are what chemists call "enantiomers"--molecules that are mirror images of each other and cannot be superposed on one another.
You can lubricate a bicycle chain with oil, but what do you do with a Mars rover or a red-hot conveyor belt in the steel industry? Very special nanomaterials have now been studied by the TU Wien together with research groups from Saarbrücken (Germany), Purdue University in the USA and the Universidad de Chile (Santiago, Chile).
Scientists have produced a comprehensive roadmap of muscle aging in mice that could be used to find treatments that prevent decline in muscle mobility and function, according to a report published today in eLife.
The study reveals which molecules in the muscle are most significantly altered at different life stages, and shows that a molecule called Klotho, when administered to mice in old, but not very old, age, was able to improve muscle strength.
The brain's auditory system tracks the speed and location of moving sounds in the same way the visual system tracks moving objects. The study recently published in eNeuro lays the groundwork for more detailed research on how humans hear in dynamic environments.
Optimal cell function requires a fine balance between the synthesis and degradation of biomolecules. Autophagy is the process by which cells degrade and recycle their own components, helping to clean up and maintain the cell's internal environment and ensure the smooth functioning of cellular processes. Autophagy is strongly induced when cells are subjected to stresses like nutrient deprivation, acting under such conditions to supply nutrients through its breakdown of unneeded cellular material.
It will take until at least 2080 before women make up just one-third of Australia's professional astronomers, an analysis published today in the journal Nature Astronomy reveals.
"Astronomers have been leaders in gender equity initiatives, but our programs are not working fast enough," says Professor Lisa Kewley, director of the ARC Centre of Excellence for All-Sky Astrophysics in 3 Dimensions (ASTRO 3D).
Over the last 200 years, researchers have worked towards understanding the global distribution of species and ecosystems. But so far even the basic knowledge on the global geography of genetic diversity was limited.
Psoriasis is a common inflammatory skin condition. The underlying genetic factors have not yet been sufficiently researched. The skin inflammation is usually triggered by external factors such as infections or stress. A research team at the Institute of Cancer Research of the Medical University of Vienna has now managed to identify a new factor in signal transmission of the immune system that plays a major role in the development of a psoriatic episode. The scientists have shown that symptoms can be alleviated by inhibiting the "c-Jun" protein in signal transmission.
Atlantic bluefin tuna have returned to UK waters and can once again be seen during the summer and autumn months.
Their numbers appear to be increasing, following a long period of absence linked to population decline, according to research led by Cefas and the University of Exeter.
Marine scientists in the UK and Ireland have analysed multiple datasets, spanning a 16-year period, to document the increase in bluefin, which arrive into the waters of the Celtic Seas and off South West England, the Scilly Isles, and North West Ireland to feed in late summer and autumn.
The Andes Mountains of South America are the most species-rich biodiversity hotspot for plant and vertebrate species in the world. But the forest that climbs up this mountain range provides another important service to humanity.
Andean forests are helping to protect the planet by acting as a carbon sink, absorbing carbon dioxide and keeping some of this climate-altering gas out of circulation, according to new research published in Nature Communications.
