Milking the umbilical cord--gently squeezing the cord and pushing the contents into the newborn's abdomen before clamping the cord--could increase the risk for severe intraventricular hemorrhage, or bleeding into the brain's fluid-filled cavities, in extremely preterm infants, according to results of a study funded by the National Institutes of Health that was halted for safety concerns.
HAMILTON, ON (Nov. 19, 2019) - There has been interest in cannabis being used as a replacement drug for people with opioid use disorder, but research at McMaster University has found it doesn't work.
The research team looked at all research on the effects of cannabis use on illicit opioid use during methadone maintenance therapy, which is a common treatment for opioid use disorder, and found six studies involving more than 3,600 participants.
Electricity supply is one of the biggest CO2 emitters globally. To keep global warming well below 2°C, several paths lead to zero emissions in the energy sector, and each has its potential environmental impacts - such as air and water pollution, land-use or water demand. Using a first-time combination of multiple modelling systems, an international team of researchers led by the Potsdam Institute for Climate Impact Research (PIK) has now quantified the actual benefits and downsides of three main roads to decarbonisation.
Complications following a procedure to treat tongue-tie in babies are occurring that can result in admission to hospital, something a University of Otago paediatrician says needs to be better understood by both health practitioners and parents.
Paediatrician, Associate Professor Ben Wheeler, and his team of researchers from the New Zealand Paediatric Surveillance Unit recently undertook a survey which shows complications including breathing problems, pain, bleeding, weight loss and poor feeding occurred in babies following minor surgery for tongue-tie (ankyloglossia).
The discovery of gases released from deep beneath the Earth's crust could help to explain Southern Africa's unusual landscape, a study suggests.
Scientists have long puzzled over why areas such as South Africa's Highveld region are so elevated and flat, with unexpectedly hot rocks below the surface.
Geologists have revealed that carbon dioxide-rich gases bubbling up through natural springs in South Africa originate from a column of hot, treacle-like material - called a hotspot - located deep inside the Earth.
The South Pole-Aitken (SPA) is the largest and deepest basin on the Moon, theoretically opening a window into the lunar lower crust and likely into the upper mantle. However, compositional information of the SPA basin was mainly obtained from orbital remote sensing. Chang'E-4 landed in the SPA Basin, providing a unique chance for in situ probing the composition of the lunar interior. The landing site is located on ejecta strips radiating from Finsen crater, which lies ~135 km to the northeast.
15-meter high waves that pushed boulders the weight of a Leopard tank inland: This is more or less how one can imagine the tsunami that hit the coast of today's Sultanate of Oman about 1,000 years ago, as concluded by a recent study by the universities of Bonn, Jena, Freiburg and RWTH Aachen. The findings also show how urgently the region needs a well-functioning early warning system. But even then, coastal residents would have a maximum of 30 minutes to get to safety in a similar catastrophe.
Embryonic stem cells (ESCs) are distinguished by their dual ability to self-renew and their potential to differentiate, both of which require tight regulatory control. During the differentiation of ESCs, various cells develop into specialised cell types such as skin cells, nerve cells, muscle cells, etc. While our understanding of ES cell regulation has been dominated by transcriptional and epigenetic models, the role of post-transcriptional regulation via nuclear RNA decay has remained less explored.
Researchers from McMaster University have discovered striking variation in the underlying genetic machinery that orchestrates sexual differentiation in frogs, demonstrating that evolution of this crucial biological system has moved at a dramatic pace.
A team of biologists examined more than two dozen species of Pipidae, a family of frog found in tropical South America and sub-Saharan Africa, which includes African clawed frogs, a smooth-skinned frog with webbed feet and claws on the hind legs.
MADISON - There's a long-standing belief in the freshwater fishing community that once anglers find it too hard to land a particular fish for their dinner plate, they either move on to fishing for different species or fish in new waters, giving depleted populations time to rebound.
BLOOMINGTON, Ind. -- Indiana University researchers have identified a mechanism involving the body's ability to resist fungal infection. The work could help advance research on cancer therapies that use the body's own immune system to fight disease.
In a study published Nov. 18 in the journal of the Proceedings of the National Academy of Sciences, IU scientist Yan Yu and colleagues found that two immune receptors -- named Dectin-1 and TLR2 -- must work together to trigger an inflammatory response that resists fungal infection.
INFORMS Journal Management Science New Study Key Takeaways:
There is growing concern that digital platforms are contributing to the U.S. drug epidemic.
Over a period of more than 10 years after Craigslist's founding, there was a nearly 15% increase in drug abuse treatment admissions, 5.7% increase in drug abuse violations and 6% increase in drug overdose deaths.
The impact of online drug sales is higher in areas typically thought to be at a lower risk for drug abuse.
NASA analyzed the cloud top temperatures in Typhoon Kalmaegi using infrared light to determine the strength of the storm. Kalmaegi is known locally as Ramon in the Philippines where warnings are in effect.
Decades after farmland was abandoned, plant biodiversity and productivity struggle to recover, according to new University of Minnesota research.
Published in the journal Nature Ecology & Evolution, researchers examined 37 years of data tied to plant biodiversity (i.e., number of different species) and plant productivity (i.e., biomass or amount of plants) related to 21 grasslands and savannas in Minnesota. Most of these fields had been ploughed and abandoned for agricultural use between one and 91 years prior.
For older adults, Fitbits and other activity trackers may be popular gifts, but they may not be used for very long.
While counterintuitive, engaging in competition with family and friends decreases the odds of long-term use among older adults, perhaps because they feel it's demotivating, according to a new Michigan State University study.
And wanting to lose weight, become more active and monitor health doesn't seem to influence length of use either. But technological savviness does.
