Neutrinos seen in the clustering of galaxies
In early times, the universe was an energetic mix of strongly interacting particles. The first particles to break free from this dense soup were neutrinos, the lightest and most weakly interacting particles of the Standard ...

A new sequencing method to detect DNA modifications of relevance to cancer
Ludwig Cancer Research scientists report in the current issue of Nature Biotechnology a new and improved method to detect chemical modifications to DNA. These modifications—or "epigenetic" marks—help control gene expression ...

Simulating meteorite impacts in the lab
A U.S.-German research team has simulated meteorite impacts in the lab and followed the resulting structural changes in two feldspar minerals with X-rays as they happened. The results of the experiments at DESY and at Argonne ...

Fiery sighting: A new physics of eruptions that damage fusion experiments
Sudden bursts of heat that can damage the inner walls of tokamak fusion experiments are a hurdle that operators of the facilities must overcome. Such bursts, called "edge localized modes (ELMs)," occur in doughnut-shaped ...

Manipulation of gossypol-containing glands in cotton can boost plant's natural defenses
Development of a cotton plant with stronger natural defenses due to a greater gland density and thus more gossypol in the leaves could soon be a reality, according to a Texas A&M AgriLife Research plant biotechnologist in ...

New findings reveal the behavior of turbulence in the exceptionally hot solar corona
The sun defies conventional scientific understanding. Its upper atmosphere, known as the corona, is many millions of degrees hotter than its surface. Astrophysicists are keen to learn why the corona is so hot, and scientists ...
