Water is key in catalytic conversion of methane to methanol

Scientists reveal new details that explain how a highly selective catalyst converts methane, the main component of natural gas, to methanol, an easy-to-transport liquid fuel and feedstock for making plastics, paints, and other commodity products. The findings could aid the design of even more efficient/selective catalysts to make methane conversion an economically viable and environmentally...

Gravitational waves could prove the existence of the quark-gluon plasma

According to modern particle physics, matter produced when neutron stars merge is so dense that it could exist in a state of dissolved elementary particles. This state of matter, called quark-gluon plasma, might produce a specific signature in gravitational waves. Physicists have now calculated this process using supercomputers.

Better understanding of nature's nanomachines may help in design of future drugs

Many of the drugs and medicines that we rely on today are natural products taken from microbes like bacteria and fungi. Within these microbes, the drugs are made by tiny natural machines known as nonribosomal peptide synthetases (NRPSs). A research team has gained a better understanding of the structures of NRPSs and the processes by which they work. This improved understanding of NRPSs could...

Sun is less active than similar stars

By cosmic standards the sun is extraordinarily monotonous. For the first time, the scientists compared the sun with hundreds of other stars with similar rotation periods. Most displayed much stronger variations. This raises the question whether the sun has been going through an unusually quiet phase for several millennia.

Supercurrent -- a current flowing without energy loss -- detected at edge of a superconductor with topological twist

The existence of superconducting currents, or supercurrents, along the exterior of a superconductor, has been surprisingly hard to find. Now, researchers have discovered these edge supercurrents in a material that is both a superconductor and a topological semi-metal. This evidence for topological superconductivity could help provide the foundation for applications in quantum computing and other...

Scientists identify a new potential reservoir of latent HIV

Scientists have describe a class of cells that preferentially support latent infection by HIV. These cells are characterized by a surface protein called CD127 and are found in tissues such as lymph nodes, which are thought to harbor a larger share of the HIV reservoir than blood does.

Naked mole-rats need carbon dioxide to avoid seizures and here's why

African naked mole-rats are sometimes referred to as animal superheroes. They resist cancer, tolerate pain, and live a remarkably long time. They're also known for their ability to handle high levels of carbon dioxide and can go for several minutes without oxygen. But researchers say they may have found the mole-rats' kryptonite: they need high levels of carbon dioxide to function.
