A Finnish research group has found strong evidence for the presence of exotic quark matter inside the cores of the largest neutron stars in existence. The conclusion was reached by combining recent results from theoretical particle and nuclear physics to measurements of gravitational waves from neutron star collisions.

All normal matter surrounding us is composed of atoms, whose dense nuclei, comprising protons and neutrons, are surrounded by negatively charged electrons...

Researchers Identify Mechanisms that make Skin a Protective Barrier

A Mount Sinai research team has identified one of the mechanisms that establish the skin as a protective barrier, a breakthrough that is critical to understanding and treating common skin conditions including eczema and psoriasis, according to a study published Thursday, May 28, in the scientific journal Genes & Development.

One of the most important roles of the skin is to act as a barrier that prevents water loss and protects the skin from pathogens. Failure of this protective function contributes to dermatological diseases. The research team led by Sarah E...

People love their electric cars. But not so much the bulky batteries and related power systems that take up precious cargo space. Help could be on the way from a gallium oxide-based transistor under development at the University at Buffalo.

In a study published in the June edition of IEEE Electron Device Letters, electrical engineers describe how the tiny electronic switch can handle more than 8,000 volts, an impressive feat considering it’s about as thin as a sheet of paper.

The tr...

Mergers between Galaxies trigger activity in their Core

Active galactic nuclei (AGNs) play a major role in galaxy evolution. Astronomers from SRON and RuG have now used a record-setting sample of galaxies to confirm that galaxy mergers have a positive effect on igniting AGNs. They were able to compile about 10 times more pictures of merging galaxies than previous studies by using a machine-learning algorithm.

One of the bigger questions in astronomy is how galaxies evolve from clouds of gas and dust to the beautiful spiral structures observed in our galactic neighborhood. So-called active galactic nuclei (AGNs) comprise interesting research objects to answer part of the question, because there appears to be co-evolution between AGNs and galaxies...
