High-precision X-ray observations confirm binary star system shoots cosmic rays An international collaboration operating NASA’s NuSTAR satellite has revealed that two of the biggest stars in the galaxy are capable of creating cosmic rays. Their results were published in Nature Astronomy this month. In the time it takes you to read this sentence,… Read more
X-ray polarimetry resolves shape of matter around Cygnus X-1 black hole In an international collaboration between Japan and Sweden, scientists clarified how gravity affects the shape of matter near the black hole in binary system Cygnus X-1. Their findings, which were published in Nature Astronomy this month, may help scientists further understand the… Read more
Protein linked with depression shows promise as new drug target Depression is a mental disorder that affects over 300 million people around the world. While treatments exist, many of them are based on one hypothesis of how depression arises. Patients that do not fit this mold may not be getting benefits. A study… Read more
Microgravity conditions affect DNA methylation of muscle cells, slowing their differentiation Astronauts go through many physiological changes during their time in spaceflight, including lower muscle mass and slower muscle development. Similar symptoms can occur in the muscles of people on Earth’s surface, too. In fact, it could affect everyone to some extent later in… Read more
Logistic regression analysis model predicts ideal chiral crystal Engineers and chemists at Hiroshima University successfully used the same technology at the core of facial recognition to design chiral crystals. This is the first study reporting the use of this technology, called logistic regression analysis, to predict which chemical groups are best for making chiral… Read more
An international team of researchers found how cancer cells respond to DNA damage signaling when in low oxygen, or hypoxia. Through comprehensive gene expression analyses, the team determined how one family of genes controls DNA damage response, as well as how it weakens the effectiveness of anticancer therapies. Our bodies have strict molecular mechanisms… Read more
