University of Chicago researchers find human brain still evolving
Human evolution, University of Chicago researchers report, is still under way in what has become our most important organ: the brain. view more (2005-09-09)
Employers still failing to accommodate disabled job seekers
These were the findings of a study published today, Friday, 10 March, in the Journal of Occupational and Organizational Psychology, by Dr. Chris Jackson and Dr. Kate Willen, of Surrey University, and Professor Adrian Furnham, of University College London. view more (2000-03-03)
Blood Lactate Measurement Could Lead To Earlier Identification Of Patients For Liver Transplant (p 558)
Arterial blood lactate measurement could rapidly and accurately identify patients who might die from paracetamol-induced acute liver failure, conclude authors of a study in this week's issue of THE LANCET. Its use is likely to improve the speed and accuracy of selection of appropriate patients for transplantation. King's College Hospital (KCH)... view more... (2002-02-13)
Novel approach for rapid identification and development of malaria vaccines
Malaria is the world's most frequent parasitic disease, affecting more than 100 countries in the tropical zones, mostly in Africa, and 40% of the world population, with more than a million deaths per year. view more (2007-07-25)
Good housekeeping: why do shelter-dwelling caterpillars fling their frass?
Caterpillars of the silver-spotted skipper butterfly ballistically eject their individual fecal pellets (frass) as far as 40 body lengths away from their resting places in leaf shelters. Why do these and many other shelter-dwelling caterpillars go to such great lengths to distance themselves from their waste? In a paper to appear in the April... view more... (2003-04-08)
History of human cannibalism eats away at researchers
In a new study published by the journal Genome Research, a team of scientists reports that 'mad cow'-like diseases have not been a major force in human history, nor have been cannibalistic rituals that are known to be associated with disease transmission. view more (2006-01-04)
Strongest medical evidence seldom considered newsworthy
The strongest medical evidence is seldom regarded as newsworthy and is underreported in British newspapers, according to researchers in this week's BMJ. A team at Bristol University and the University of Berne, Switzerland examined two stages on the path to newspaper coverage - selection by medical journal editors of studies for press releases and... view more...

Key brain regulatory gene shows evolution in humans
Researchers have discovered the first brain regulatory gene that shows clear evidence of evolution from lower primates to humans. view more (2005-12-13)
Female Butterflies Go for Sparkle - Not Size - When Choosing to Mate
Size doesn't matter, at least not the size of the eyespots on a male butterfly's wings when female butterflies consider potential mates. view more (2005-06-29)
UF researchers devise way to calculate rates of evolution
"Survival of the fittest" has popularly described evolution for more than a century, but a new study published in the Royal Society journal Biology Letters provides further evidence that random genetic mutations over millions of years may also play a powerful role. view more (2007-10-05)
Study of espresso coffee quality
The preparation of Espresso Coffee (EC) is influenced by factors related to the coffee and water and other technical conditions related to the machine. Susana Andueza has presented her doctoral thesis about Influence of technological variables on espresso coffee quality. Antioxidant and pro-oxidant capacity of coffee in the University of Navarre.... view more... (2004-02-12)
Researchers discover key mechanism to emergence of deadly strep bacteria
The incidence of serious strep infections has risen dramatically in the last three decades, and this increase is largely attributed to the spread around the globe of a single strain of strep known as the invasive M1T1 clone. view more (2007-07-16)
Charting ever-changing genomes
Instead of immutable proprietary software, any species' genetic information resembles open source code that is constantly tweaked and optimized to meet the users' specific needs. view more (2007-07-20)
Monarch butterflies help explain why parasites harm hosts
It's a paradox that has confounded evolutionary biologists since Charles Darwin published On the Origin of Species in 1859: Since parasites depend on their hosts for survival, why do they harm them? view more (2008-05-15)
Complexity constrains evolution of human brain genes
Despite the explosive growth in size and complexity of the human brain, the pace of evolutionary change among the thousands of genes expressed in brain tissue has actually slowed since the split, millions of years ago, between human and chimpanzee. view more (2006-12-26)
Worker ants of the world, unite! You have nothing to lose but your fertility
The highly specialized worker castes in ants represent the pinnacle of social organization in the insect world. As in any society, however, ant colonies are filled with internal strife and conflict. So what binds them together? More than 150 years ago, Charles Darwin had an idea and now he's been proven right. view more (2008-11-20)
Gene duplication allowed pigs to have more babies
With increasing numbers of whole genomes being sequenced, researchers are keen to analyse the functions of the genes they contain and the proteins these genes encode. Yet, according to researchers writing in BMC Biology, to fully understand any genome, researchers must use palaeontology, geology and chemistry to help them discover the reasons why... view more...

DNA size a crucial factor in genetic mutations, study finds
Researchers at Stanford University have created a larger-than-normal DNA molecule that is copied almost as efficiently as natural DNA. view more (2005-10-27)
Advances in liver surgery enable the prospect of curative treatment for more patients
Although many prognostic factors predicting survival and cancer recurrence in patients undergoing surgery for colorectal liver metastases are already identified, the effects of newly introduced technologies and new drugs in the treatment of these patients are still poorly studied because of the presence of many involved factors. view more (2009-06-15)
Using plants and microbes to purify polluted industrial wastewater
Wetlands are nature's water filters. They collect water around river mouths and marshes, and whole communities of plants and micro-organisms feed off detritus in these murky depths. Conventional chemical treatments of industrial waters consume cash, energy and time. Wetlands, by contrast, grow and clean themselves while they act as... view more... (2003-10-07)
