Trial: Cleaner Cookstove Fuel Not Enough to Improve Infant Health
Swapping out liquid petroleum (LP) for biomass cooking fuel during pregnancy made little difference for infant growth or pneumonia rates, two analyses of a randomized controlled trial in low-resource settings revealed. The cooking fuel intervention successfully reduced exposure to household air pollution as measured by fine particles with an aerodynamic diameter of ≤2.5 μm (PM2.5) […]
7 Sneaky Phone Habits That Could Be Signs Of Anxiety
Tim Robberts via Getty Images Your cellphone can not only fuel your anxiety, but certain cellphone habits could be a manifestation of your anxiety. Your cellphone can tell you a lot — the weather, your plans for the weekend, the latest news. Therapists say it can also clue you into how you’re feeling. Specifically, certain […]
PCI vs CABG: Does Age Inform Choice for Left Main Coronary Artery Disease?
BOSTON — Adding fuel to the controversy of revascularization for left main disease, patients had better survival after coronary artery bypass grafting (CABG) surgery than percutaneous coronary intervention (PCI) in an all-comers nationwide registry study. The incidence of all-cause mortality stayed greater up to 7 years after PCI versus CABG (adjusted HR 1.59, 95% CI […]
4D composite printing can improve the wings of drones
The aviation industry faces multiple pressures from higher fuel costs and increased scrutiny over the environmental and quality-of-life impacts from its aircraft. Researchers are looking for new methods of keeping expenses down while improving overall efficiency, and the relatively new market of unmanned aerial vehicles (UAVs) — or drones — is no exception. UAVs are […]
Carbon-coated nickel enables fuel cell free of precious metals
A nitrogen doped carbon-coated nickel anode can catalyze an essential reaction in hydrogen fuel cells at a fraction of the cost of the precious metals currently used, Cornell University researchers have found. The new discovery could accelerate the widespread use of hydrogen fuel cells, which hold great promise as efficient, clean energy sources for vehicles […]
Researchers use supercomputers for largest-ever turbulence simulations of its kind
From designing new airplane wings to better understanding how fuel sprays ignite in a combustion engine, researchers have long been interested in better understanding how chaotic, turbulent motions impact fluid flows under a variety of conditions. Despite decades of focused research on the topic, physicists still consider a fundamental understanding of turbulence statistics to be […]
