Not all stars are like the sun, so not all planetary systems can be studied with the same expectations. New research from a University of Washington-led team of astronomers gives updated climate models for the seven planets around the star TRAPPIST-1. The work also could help astronomers more effectively study planets around stars unlike our sun, and better use the limited, expensive resources of the James Webb Space Telescope, now expected to launch in 2021.

Chase Cornelison is a post-doctoral researcher at Virginia Tech and lead author of an article published in Scientific Reports that details a solution to stopping the spread of glioblastoma in the brain.

A team of researchers may have found a solution to stopping the spread of glioblastoma with a new drug and cancer treatment method. In people who have glioblastoma, the deadliest form of brain cancer, this fluid has a much higher pressure, causing it to move fast and forcing cancer cells to spread. And a common cancer therapy, which inserts a drug directly into the tumor with a catheter, can make this fluid move even faster.

This is an artist’s impression based on published scientific data on the HR 8799 solar system. The magenta, HR 8799c planet is in the foreground. Compared to Jupiter, this gas giant is about seven times more massive and has a radius that is 20 percent larger. HR 8799c’s planetary companions, d and b are in the background, orbiting their host star. Credit: W. M. Keck Observatory/Adam Makarenko/C. Alvarez

Researchers are perfecting technology to one day look for signs of alien life. Astronomers have gleaned some of the best data yet on the composition of a planet known as HR 8799c – a young giant gas planet about 7 times the mass of Jupiter that orbits its star every 200 years.

The team used state-of-the art instrumentation at the W. M...

The illustration shows the atoms of a gold cone exposed to a strong electric field. We also see the field (around the tip of the cone) that excites the gold atoms. They break almost all their connections to each other and the surface layers begin to melt. Credit: Alexander Ericson

When the tension rises, unexpected things can happen – not least when it comes to gold atoms. Researchers from, among others, Chalmers University of Technology, Sweden, have now managed, for the first time, to make the surface of a gold object melt at room temperature.

Ludvig de Knoop, from Chalmers’ Department of Physics, placed a small piece of gold in an electron microscope...
