The chaotic cores of Perseus protostars
The formation of a star has a simple tale. A region of interstellar gas collapses under its own weight, eventually forming a dense protostar surrounded by a disk of gas and dust. The protostar and the disk rotate in the same plane, and often jets of.....»»
Video: Why we need to preserve maritime forests
While collecting cores from oak trees on Fire Island National Park, Nicole Davi, a dendrochronologist who works at the Climate School's Lamont-Doherty Earth Observatory, explains the critical role maritime forests play in protecting our coastal commu.....»»

Scientists retrieve rare methane hydrate samples for climate and energy study
A scientific drilling mission in the Gulf of Mexico has returned with 44 cores from a methane hydrate reservoir deep under the seafloor. Globally, energy-rich methane hydrates hold an estimated 15% of the world's organic carbon but are poorly underst.....»»
Scientists tame chaotic protein fueling 75% of cancers
MYC is the shapeless protein responsible for making the majority of human cancer cases worse. UC Riverside researchers have found a way to rein it in, offering hope for a new era of treatments......»»
"Stellar paternity tests" match orphaned stars to their Milky Way origins
In the chaotic environment of open star clusters, strong gravitational interactions between bodies can launch individual stars far outside the cluster, even outside our galaxy, the Milky Way. Now, for the first time researchers have mapped several of.....»»

The most massive neutron stars probably have cores of quark matter
Atoms are made of three things: protons, neutrons, and electrons. Electrons are a type of fundamental particle, but protons and neutrons are composite particles made of up and down quarks. Protons have 2 ups and 1 down, while neutrons have 2 downs an.....»»

Iron snow ebb and flow may cause magnetic fields to come and go
Just as snow crystals form in the upper atmosphere, then fall to lower, warmer elevations and melt, scientists believe a phenomenon called iron snow happens in the molten iron cores of some planetary bodies. Cooling near the core-mantle boundary crea.....»»
Aaarr matey! Life on a 17th century pirate ship was less chaotic than you think

Further evidence for quark-matter cores in massive neutron stars
Neutron-star cores contain matter at the highest densities reached in our present-day universe, with as much as two solar masses of matter compressed inside a sphere of 25 km in diameter. These astrophysical objects can indeed be thought of as giant.....»»
Webb finds icy complex organic molecules around protostars
In the quest to understand how and where life might arise in the galaxy, astronomers search for its building blocks. Complex Organic Molecules (COMs) are some of those blocks, and they include things like formaldehyde and acetic acid, among many othe.....»»
