Galaxies were once thought of as `island universes` evolving slowly in complete isolation. This is now known not to be the case. By using the world`s most powerful X-ray observatories, UK astronomers are discovering that most of these gigantic star systems interact with each other in a wide variety of ways.
During the UK National Astronomy Meeting in Bristol on Thursday 11 April, Dr. Andrew Read (University of Birmingham) will present new results from the Chandra and XMM-Newton spacecraft ab
Results of a UK study in this week’s issue of THE LANCET suggest that the antianginal drug nicorandil could reduce the risk of cardiovascular disease associated with angina.
Angina occurs in 10% of men aged older than 60 years in the UK (10-15 years later in women), and is a common underlying cause of coronary heart disease (CHD). Aspirin, angiotensin-converting-enzyme (ACE) inhibitors, and statins reduce the risk of cardiovascular events in subgroups of patients with stable angina; however,
The phrase “king of the jungle” invariably conjures up the image of a majestic, tawny cat with a fluffy mane framing its face. But in fact not all male lions have big hair. In Kenyas Tsavo National Park–famed for the man-eating lions that reportedly terrorized railroad workers there in the late 1800s–a number of males lack manes altogether. Exactly why this should be the case–or why any lions should have manes, for that matter–has been difficult to explain. To that end, the results of a new
Astronomers use galaxies to reckon a subatomic particles mass.
By mapping hundreds of thousands of galaxies, astronomers have estimated the mass of the neutrino. They have also calculated the contribution that this mysterious subatomic particle makes to the total mass of the Universe.
The neutrino weighs no more than one-billionth of the mass of a hydrogen atom, Ofer Lahav of the University of Cambridge told the annual UK National Astronomy Meeting in Bristol today. Yet
Neutrinos, the lightest of the known elementary particles, weigh a billionth (one part in a thousand million) of a hydrogen atom at most, and can account for no more than one-fifth of the dark matter in the Universe, according to findings by astronomers in Cambridge, who used data from the Anglo-Australian telescope 2dF Galaxy Redshift Survey (2dFGRS). The results will be presented by Dr Ofer Lahav of Cambridge University at the UK National Astronomy Meeting in Bristol on Wednesday 10 April.
Sustainability may not be all it’s cracked up to be. That is the message in a recent paper by a hydrogeologist at Reading University . Michael Price argues that most human advances have been non-sustainable in the long term and that when we talk of ‘sustainable use’ we must define the period over which the use is planned or implemented.
Price identifies three major challenges currently facing Britain and the world. The first is that the climate, and with it the supply of water, is becoming
