Particle astrophysics articles from across Nature Portfolio Atom RSS Feed Particle astrophysics is the study of fundamental particles travelling through space, particularly those that reach the Earth. These cosmic rays include photons, protons, alpha particles and neutrinos. Some of these decay to ...
which was operated at a nominal magnetic field of 1.25 T in the centre of the magnet. The experiment was designed to detect an α-particle and a proton that emerge from quasi-elastic scattering close to 180° in the centre-of-mass frame (Fig.1). Under these...
Uniaxial pressure provides an efficient approach to control charge density waves in YBa2Cu3Oy. It can enhance the correlation volume of ubiquitous short-range two-dimensional charge-density-wave correlations, and induces a long-range three-dimensional charge density wave, otherwise only accessible at ...
Nanoparticle tracking analysis (NTA) revealed that the sEVs were present in young and aged plasma at a same order of magnitude (1.7 × 109 particles per milliliter in young plasma versus 1.04 × 109 particles per milliliter in aged plasma) and at a similar particle size (peaking...

Energetic ions in nuclear fusion devices influence the behaviour of modes at the plasma edge, potentially increasing the risk for particle losses and damage to the device. This introduces additional challenges for the development of fusion reactors. ...
Natural killer (NK) cells are lymphocytes of the innate immune system. A key feature of NK cells is their ability to recognize a wide range of cells in distress, particularly tumour cells and cells infected with viruses. They combine both direct effector
The new method of encapsulation of the acid inside liposomes seems to increase the solubility of the particle. Another way of BA delivery to the tumor tissue may be carbon nanotubes, already widely used in medicine for direct drug delivery. Binding of the BA to nanotubes, called MWCNT-BA, ...
