New Rochelle, NY, September 19, 2019-Mast cells are critically involved in immunity and immune disorders. However, they are rarely cultured ex vivo for experimental manipulation because of the difficulty in isolating useful numbers and limitations related to 2D culture. A new study reports the successful development of authenticated mast cells by culturing hematopoietic stem cells in an engineered 3D connective tissue matrix. The work is published in Tissue Engineering, a peer-reviewed journal from Mary Ann Liebert, Inc., publishers.
ROCHESTER, Minn. -- Though research shows that medication-assisted treatment can help people who are addicted to opioids, the three drugs approved by the Food and Drug Administration (FDA) are underused, according to a review of current medical data on opioid addiction in the U.S. This review appears in the October issue of Mayo Clinic Proceedings.
What The Study Did: This observational study compared major cardiovascular events (including hospitalization for heart attack, stroke, transient ischemic attack or cardiovascular death) among patients with diabetes and reduced kidney function treated with metformin or a sulfonylurea (a class of drugs to treat diabetes).

HOUSTON - (Sept. 19, 2019) - What may be viewed as the world's smallest incandescent lightbulb is shining in a Rice University engineering laboratory with the promise of advances in sensing, photonics and perhaps computing platforms beyond the limitations of silicon.
Gururaj Naik of Rice's Brown School of Engineering and graduate student Chloe Doiron have assembled unconventional "selective thermal emitters" -- collections of near-nanoscale materials that absorb heat and emit light.
WASHINGTON - A toxic cocktail of chemical pollutants in U.S. drinking water could result in more than 100,000 cancer cases, according to a peer-reviewed study from Environmental Working Group - the first study to conduct a cumulative assessment of cancer risks due to 22 carcinogenic contaminants found in drinking water nationwide.
Women who give birth to singleton babies following assisted reproductive technologies including vitro fertilisation (IVF) are at greater risk of developing gestational diabetes than those who conceive naturally, according to a meta-analysis involving over almost 2 million singleton pregnancies.
Previous research has shown that people born weighing 2.7 kg (6 lbs) or less face an increased risk of developing type 2 diabetes (T2D) as adults. New research being presented at this year's European Association for the Study of Diabetes (EASD) Annual Meeting in Barcelona, Spain (16-20 September) is the first study to show that babies born underweight are more likely to develop type 2 diabetes at a younger age (by more than one year) and have less severe obesity at the time of diabetes diagnosis with higher concentrations of HDL cholesterol (known as good cholesterol).
Organizations endorsing a win-at-all-costs environment may find this management style good for the bottom-line, but it could come a price. Teamwork and civility between co-workers are severely compromised which can lead to major issues down the road (remember Enron?).
To process information, photons must interact. However, these tiny packets of light want nothing to do with each other, each passing by without altering the other. Now, researchers at Stevens Institute of Technology have coaxed photons into interacting with one another with unprecedented efficiency -- a key advance toward realizing long-awaited quantum optics technologies for computing, communication and remote sensing.
Films of platinum only two atoms thick supported by graphene could enable fuel cell catalysts with unprecedented catalytic activity and longevity, according to a study published recently by researchers at the Georgia Institute of Technology.
Platinum is one of the most commonly used catalysts for fuel cells because of how effectively it enables the oxidation reduction reaction at the center of the technology. But its high cost has spurred research efforts to find ways to use smaller amounts of it while maintaining the same catalytic activity.
A University of Wyoming researcher and his team discovered that weathering of subsurface rock in the Southern Sierra Nevada Mountains of California occurs due more to rocks expanding than from chemical decomposition, as previously thought.
Porosity, the void space in rock, was conventionally thought to be produced when water flows through the rock, thus resulting in minerals chemically dissolving. Because mountain watershed provides large reservoirs of water, the new findings are relevant to water resource management throughout the U.S.
DURHAM, N.C. -- Reducing fossil fuel emissions steadily over coming years will prevent millions of premature deaths and help avoid the worst of climate change without causing the large spike in short-term warming that some studies have predicted, new analysis by researchers at Duke University and the University of Leeds finds.
CHARLOTTESVILLE, Va. - Mechanical engineers at the University of Virginia School of Engineering, leading a collaboration with biologists from Harvard University, have created the first robotic fish proven to mimic the speed and movements of live yellowfin tuna.
When the Global Precipitation Measurement mission or GPM core satellite passed over the Eastern Pacific Ocean, it flew over the eastern side of Tropical Storm Mario and measured rainfall.
In the future, you could be your very own fountain of youth - or at least your own skin repair reservoir. In a proof-of-concept study, researchers from North Carolina State University have shown that exosomes harvested from human skin cells are more effective at repairing sun-damaged skin cells in mice than popular retinol or stem cell-based treatments currently in use. Additionally, the nanometer-sized exosomes can be delivered to the target cells via needle-free injections.
