Globular star clusters, dense bunches of hundreds of thousands of stars, contain some of the oldest surviving stars in the Universe. A new international study of globular clusters outside our Milky Way Galaxy has found evidence that these hardy pioneers are more likely to form in dense areas, where star birth occurs at a rapid rate, instead of uniformly from galaxy to galaxy.

Astronomers used the NASA/ESA Hubble Space Telescope to identify over 11 000 globular clusters in the Virgo cluster of galaxies, most of which are more than 5 billion years old. Comprised of over 2 000 galaxies, the Virgo cluster is located about 54 million light-years away and is the nearest large galaxy cluster to Earth. Along with Virgo, the sharp vision of Hubble's Advanced Camera for Surveys (ACS) resolved the star clusters in 100 galaxies of various sizes, shapes, and brightness – even in faint, dwarf galaxies.


You may have laughed when you read in history books that in years gone by maggots were used to cure disease.

Laugh no more. It’s not uncommon for someone to suffer from chronic infected wounds for 18 months, despite all sorts of conventional treatment, but when maggots are applied to the same wound they can often begin to clear infection in just a few days. They have even been known to save people from having limbs amputated.

MRSA infections cause suffering, amputations and death, not to mention the estimated £1 billion cost to the NHS. Between 2002 and 2006, 6,201 deaths in England and Wales involved MRSA and 15,683 deaths in England and Wales involved C. difficile. The rapid rise in antibiotic-resistant bacteria means that scientists urgently need to find a solution.

A study published in the International Journal of Obesity says that eating two eggs for breakfast, as part of an overall reduced-calorie diet, helps overweight adults lose more weight and feel more energetic than those who eat a bagel breakfast of equal calories.(1) This study supports previous research, published in the Journal of the American College of Nutrition, which showed that people who ate eggs for breakfast felt more satisfied and ate fewer calories at the following meal.

Metabolic changes responsible for the evolution of our unique cognitive abilities indicate that the brain may have been pushed to the limit of its capabilities, according to research published today in Genome Biology.

This adds weight to the theory that schizophrenia is a costly by-product of human brain evolution.

Philipp Khaitovich, from the Max Planck Institute for Evolutionary Anthropology and the Shanghai branch of the Chinese Academy of Sciences, led a collaboration of researchers from Cambridge, Leipzig and Shanghai who investigated brains from healthy and schizophrenic humans and compared them with chimpanzee and rhesus macaque brains.

The first thing iRobot Corporation wants you to know, because they have been asked so many times, is that the Packbot is no Terminator - and never will be.

Robots in the military are not the stuff of science fiction but their mission parameters are very specific - and they are all teleoperated, meaning that there is someone operating the robot from a remote location, perhaps with a joystick and a computer screen.

While this may seem like a caveat in plans to add robots to the military, it is actually very important to keep humans involved in the robotic operations.


A revised outlook for the Arctic 2008 summer sea ice minimum shows ice extent will be below the 2005 level but not likely to beat the 2007 record, say researchers with DAMOCLES (Developing Arctic Modeling and Observing Capabilities for Long-term Environmental Studies), an integrated ice-atmosphere-ocean monitoring and forecasting system designed for observing, understanding and quantifying climate changes in the Arctic.

DAMOCLES will dispatch eleven research missions into the Arctic this autumn to better understand the future of the sea ice.

Chances that the 2008 ice extent will fall below last year's record minimum is about 8 percent, researchers forecast after having run a number of different models predicting the fate of the Arctic sea ice this summer. But there is still reason for concern; the scientists are almost certain the ice extent will fall below the minimum of 2005, which was the second lowest year on record. With a probability of 80% the minimum ice extent in 2008 will be in the range between 4.16 and 4.70 million km2.
