The use of nanoparticles in drug delivery offers key advantages: they can enable targeted drug delivery, protect active ingredients from premature degradation, extend their duration of action in the body and reduce side effects. However, as soon as nanoparticles come into contact with blood, proteins from the blood adsorb onto their surface—forming a so-called protein corona. This corona influences whether the particles are taken up by cells, how they distribute in the body or whether the immune system recognizes and attacks them.

Famous oddball quasar isn't X-ray weak after all, astronomers say

For more than two decades, the quasar PHL 1811 has been considered the prototype of a rare class of "intrinsically X-ray weak" quasars, thought to produce unusually little X-ray radiation. But in 2024, the Einstein Probe spacecraft caught the object in a bright X-ray flare. In a new study, astronomers combined that observation with more than 20 years of archival data to revisit the mystery. The findings were published in The Astrophysical Journal on July 28.
