Using XMM-Newton, astronomers have obtained the world’s deepest ‘wide screen’ X-ray image of the cosmos to date. Their observations show newly discovered clusters of galaxies and provide insights into the structure of the distant Universe…

Unlike grains of sand on a beach, matter is not uniformly spread throughout the Universe. Instead, it is concentrated into galaxies like our own which themselves congregate into clusters. These clusters are ‘strung’ throughout the Universe in a web-like st

During summertime ozone near the Earth’s surface forms in most major U.S. cities when sunlight and heat mix with car exhaust and other pollution, causing health officials to issue “ozone alerts.” But in other parts of the world, such as the tropical Atlantic, this low level ozone appears to originate naturally in ways that have left scientists puzzled. Now, NASA-funded scientists using four satellites can tell where low level ozone pollution comes from and whether it was manmade or natural.

Thirty three marine species are poised to invade Australian waters, and could seriously alter the balance of marine life or even pose a risk to human health if they reach our coasts.

In an international response to the threat, researchers from CSIRO and the Smithsonian Environmental Research Center, Maryland, have joined forces to develop a rapid response strategy to combat invasion.

CSIRO risk assessment scientists have identified the most damaging marine species from around the

Australian windpower technology is reaching out to a global market, as science, technology and industry come together in a new wind energy consulting company based in Canberra.

Former CSIRO scientists, Dr Keith Ayotte and Dr Nathan Steggel developed what is seen to be world’s best available wind resource technology, WindScape and Raptor NL.

Windscape is believed to be the leading wind mapping tool and enables power prospectors to find the windiest spots down to property boundaries

Aging has long been recognized as the worst risk factor for chronic ailments like atherosclerosis, which clogs arteries and leads to heart attacks and stroke. Yet, the mechanism by which aging promotes the clogging of arteries has remained an enigma.

Scientists at Duke University Medical Center have discovered that a major problem with aging is an unexpected failure of the bone marrow to produce progenitor cells that are needed to repair and rejuvenate arteries exposed to such environmental

Remain a hematopoetic stem cell or become a specialized blood cell?

Hematopoietic stem cells, the mother of all blood cells, face a fundamental dilemma in their lives.

Each must either remain a hematopoietic stem cell (HSC) by renewing itself or it must transform into one of eight specialized types of blood cells, such as a red blood cell, a white blood cell or a platelet.

Until recently, scientists didn’t know how the essential cells, which exist in limited a
