Microfluidic circuit for pulsatile filtration of extracellular vesicles from whole blood samples
Extracellular vesicles (EVs) are cell-secreted lipid bilayer bioparticles with a diameter of 30 to 250 nm. They are a promising source of biomarkers for liquid biopsies for early cancer diagnosis and real-time monitoring of tumor development. However.....»»
Study finds persistent proteins may influence metabolomics results
Van Andel Institute scientists have identified more than 1,000 previously undetected proteins in common metabolite samples, which persist despite extraction methods designed to weed them out......»»
Exoplanet caught in "hairpin turn" signals how high-mass gas giants form
Astronomers have discovered a planet that has the most oblong orbit ever found among transiting planets. The exoplanet's extreme circuit—which looks closer to a cucumber than a circle—follows one of the most drastically stretched-out orbits of al.....»»

Scientists develop new tool that could lead to noninvasive "liquid biopsies"
Biopsies are clinical tools commonly used to diagnose a variety of diseases or to monitor tissue for abnormal growth or even rejection of a transplant. During biopsies, tissue samples are removed from the body so they can be examined more closely, bu.....»»
Genetic cloaking of healthy cells opens door to universal blood cancer therapy

Integrating small-angle neutron scattering with machine learning enhances measurements of complex molecular structures
Small-angle scattering (SAS) is a powerful technique for studying nanoscale samples. So far, however, its use in research has been held back by its inability to operate without some prior knowledge of a sample's chemical composition. Through new rese.....»»
Biologists determine the liver is the source of free glycans in the bloodstream
In a rat study, RIKEN biologists have solved the mystery of where glycan molecules in the blood come from, tracking them down to the liver. This finding could lead to new biomarkers for liver-related diseases......»»

With its latest moon mission success, China"s space program has the US in its sights
June 25 2024 marked a new "first" in the history of spaceflight. China's robotic Chang'e 6 spacecraft delivered samples of rock back to Earth from a huge feature on the moon called the south pole–Aitken basin. After touching down on the moon's "far.....»»
Recovery of unique geological samples sheds light on formation of today"s Antarctic ice sheet
In recent years, global warming has left its mark on the Antarctic ice sheets. The "eternal" ice in Antarctica is melting faster than previously assumed, particularly in West Antarctica more than East Antarctica. The root for this could lie in its fo.....»»
Caterpillars pass down food preferences to offspring through blood
Many caterpillars are known for their specific food preferences, which they bring with them when they morph into butterflies. For instance, the monarch butterfly only feeds on milkweed plants, while the Lime butterfly feeds on lime leaves. Despite de.....»»
