The cosmic ray gun duel of Eta Carinae

The cosmic ray gun duel of Eta Carinae

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, hundreds of cosmic rays have pummeled through our bodies. Cosmic rays are mostly made of protons and electrons, with the smallest fraction made of X-rays and gamma rays. These jets of high-energy particles not only make up a sizable portion of radiation astronauts and airplane pilots receive, but they also can reach the ends of… Read more

X-ray technology reveals never-before-seen matter around black hole

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 physics of strong gravity and the evolution of black holes and galaxies. Near the center of the constellation of Cygnus is a star orbiting the first black hole discovered in the universe. Together, they form a binary system known as Cygnus X-1. This black hole is also one of the brightest sources of X-rays in… Read more

An Interview with Distinguished Researcher Yuhki Yanase

An Interview with Distinguished Researcher Yuhki Yanase

On February 1, 2013, Hiroshima University established two new programs: the “Distinguished Professors” (DP) program and the “Distinguished Researchers” (DR) program. Individuals who are part of these programs are recognized as senior and junior faculty members respectively, who are engaged in extraordinarily distinguished research activities. What is your name and specialty? My name is Yuhki Yanase. I belong the Department of Dermatology, and focus on skin disorders. My main focus is on biosensors – I develop optical biosensors that detects when cells have been triggered by an allergic reaction. Are allergies becoming more common? The number of patients with allergies is increasing because the world is cleaner! So, we are… Read more

 On February 1, 2013, Hiroshima University established two new programs: the “Distinguished Professors” (DP) program and the “Distinguished Researchers” (DR) program. Individuals who are part of these programs are recognized as senior and junior faculty members respectively, who are engaged in extraordinarily distinguished research activities.   What is your name and specialty? My name is Yaichiro Kotake – my research field is neurotoxicology. Neurotoxicology tries to determine how environmental chemicals damage the brain. What do you mean by environmental chemicals? There are countless chemicals in the world – we are aware of approximately 100 million. A proportion of those chemicals – about 100,000 chemicals surround us in our daily lives;… Read more

Individuals who are part of these programs are recognized as senior and junior faculty members respectively, who are engaged in extraordinarily distinguished research activities.  Can you introduce yourself please? My name is Kazuyoshi Ukena, my specialty in neuroendocrinology – I focus on hormones in the brain. What are you working on now? I’m investigating never before documented neuropeptides. Neuropeptides are proteins used by neuronal cells to pass signals from one to another. I have recently found a new one in the hypothalamus, the brain control center, and we have… Read more
