Microscale roughness breakthrough defies 80 years of fluid dynamics
Logically, you would think a sleek surface has optimal aerodynamics—but recent research at Tohoku University turns this fundamental principle on its head. Applying an irregular microscale surface texture reduced the aerodynamic drag of a test model. The innovation has potential a
Unusual three-way bestows magnetic sense to single-celled organism
How do microorganisms orient themselves to find the optimal habitat? Scientists have thoroughly investigated so-called magnetotactic bacteria, which use the Earth's magnetic field as a biological compass. Some eukaryotic single-celled organisms—that is, more complex organisms lik
Superworms could replace beetles for cleaning skeletal remains
An optimal ratio of 10-15 grams of larvae per gram of specimen minimized cleaning time with no bone damage. O recorte ajuda a contextualizar a pauta dentro de Tech.
'Polypill' for heart failure cuts hospitalizations and ER visits by 60% in trial
A "polypill" combining three medications recommended to treat heart failure into a single daily dose proved far more effective for patients than taking the drugs separately, a randomized clinical trial led by UT Southwestern Medical Center researchers showed. The findings, publis
Economic evaluation supports prophylactic naldemedine for opioid-induced constipation in c
Although opioids remain indispensable for pain relief in patients with advanced cancer, their use frequently results in OIC, which can substantially reduce quality of life and, in some cases, compromise the continuation of optimal pain management. Naldemedine, a peripherally acti
