New clues in the hunt for the sources of cosmic neutrinos
This illustration is an example of a hidden cosmic-ray accelerator. Cosmic rays are accelerated up to extremely high energies in dense environments close to black holes. High-energy gamma rays (marked by the “Y” gamma symbol) are blocked from escaping, while neutrinos (marked by the “V”nu symbol) easily escape and can reach the Earth.

What Happens When LIGO Texts You to Say it's Detected One of Einstein's Predicted Gravitational Waves
These plots show the signals of gravitational waves detected by the twin LIGO observatories at Livingston, Louisiana, and Hanford, Washington. The signals came from two merging black holes, each about 30 times the mass of our sun, lying 1.3 billion light-years away. LIGO, CC BY-ND
Penn State harnessing research muscle to fight infectious diseases
Andrew Read, director of the Center for Infectious Disease Dynamics and Evan Pugh Professor of Biology and Entomology at Penn State, assesses the impact of temperature fluctuations on mosquitos in the insectary at University Park. The insectary's environmental chambers allow researchers to conduct experiments involving temperature variations, insecticides, and behavioral assessments on insects. Image: Patrick Mansell

What dose of medication is best to prevent the evolution of drug resistance?
Infographic illustrating the low levels of drug-resistant microbes with a few red dots being kept in check through competition with a large amount of drug-sensitive microbes. In the second image the drug-sensitive microbes are wiped out by high doses of ant-microbe medications but the drug resistant microbes remain. In the third image with the competition removed the drug resistant microbes increase in number. CREDIT: Centers for Disease Control and Prevention and Penn State University
Now you see it, now you don't: The quasar that just disappeared
The image shows an artist's conception of the changing-look quasar as is appeared in early 2015. The glowing blue region shows the last of the gas being swallowed by central black hole as it shuts off. The spectrum is the previous one obtained by the SDSS in 2003.

Mysterious radio signals from space test Einstein's General Relativity theory
This illustration shows how two photons, one at a high frequency (nu_h) and another at a low frequency (nu_l), travel in curved space-time from their origin in a distant Fast Radio Burst (FRB) source until reaching the Earth. A lower-limit estimate of the gravitational pull that the photons experience along their way is given by the mass in the center of the Milky Way Galaxy.
