Estimation of isolation times in the Drosophila simulans complex
The Drosophila simulans species complex continues to serve as an important model system for the study of new species formation. The complex is comprised of the cosmopolitan species, D. simulans, and two island endemics, D. mauritiana and D. sechellia.   view more (2008-06-26)

Antarctic seabirds and climate change
Recent changes in Antarctic seabird populations may be linked to environmental change according to scientists reporting in the journal Science this week.

Scientists shed light on the mystery of photosynthesis
Scientists at the University of Sheffield are part of an international team that has become the first to successfully discover how the component parts of photosynthesis fit together within the cell membrane. In a paper, The native architecture of a photosynthetic membrane, published in Nature on 26... view more (2004-08-25)

Norwich scientists grow snapdragons in microchips
Scientists from the John Innes Centre (JIC)(1) and University of East Anglia(UEA)(2) in Norwich have today reported that they have been able to ‘grow’ snapdragon(3) petals in a computer. The research team used a computer programme to simulate the growth of snapdragon petals, this... view more (2003-03-10)

Discovery in plant virus may help prevent HIV and similar viruses
In a study that could lead to new ways to prevent infection by human immunodeficiency virus (HIV) and similar organisms, Purdue University researchers have been able to genetically modify a plant to halt reproduction of a related virus.   view more (2007-08-01)

Possible cause and potential treatment found for aggressive head and neck cancer
Researchers at the San Francisco VA Medical Center report that they have found a potential molecular cause for the aggressive growth and spread of human head and neck squamous cell carcinoma, a highly malignant form of cancer with a very high death rate.   view more (2006-04-24)

Antidepressants improve post-stroke 'thinking outside the box'
Antidepressant treatment appears to help stroke survivors with the kind of complex mental abilities often referred to as "thinking outside the box," according to a University of Iowa study.   view more (2007-03-05)

New reagent delivers a chemical breakthrough at FSU
"Build a better mousetrap," the saying goes, "and the world will beat a path to your door." In the complex field of organic chemistry, that path leads to Florida State University, where a newly developed substance could make the jobs of scientists throughout the world a little... view more (2007-03-16)

New method will clarify and condense complex documents
A novel method of analysis has been developed that could change the way complicated documents are assessed for bias, accuracy and consistency. The technique could be used to simplify all sorts of records. For instance long legal documents that use complex and obscure reasoning could be stripped... view more (2003-08-11)

A tiny protein plays a big role in DNA repair
Two of DNA's worst enemies, ultraviolet light and chemical carcinogens, can wreak havoc on the molecule by mutating individual nucleotides or changing its physical structure.   view more (2006-05-09)

Smart dummies allow medics to practise before they panic
Doctors and nurses are using computer controlled medical mannequins to practise their responses to medical emergencies. Research into the complex maths and physics of the body has led to sophisticated mathematical models that drive the mannequins` responses, allowing students to experience a... view more (2002-01-16)

Bringing space down to Earth to explain how stars form
In a laboratory in Nottingham, scientists are now creating the uniquely harsh conditions encountered in interstellar space. In an environment where the pressure is only one ten billion billionth (one part in 10 to the power 13) of atmospheric pressure, and the temperature a mere 10 degrees above... view more (2002-04-04)

3-D computer simulation to aid treatment of collapsed lungs
The treatment of premature babies and adults who suffer from Respiratory Distress Syndrome could be boosted by new research at The University of Manchester, as published in the Journal of Biomechanical Engineering.   view more (2006-07-26)

Astronomers find puzzling dwarf star with complex magnetic fields
Typically, little M-dwarf stars-the most common type of star in the galaxy-are cold, quiet, and dim. Now a team of astronomers led by Edo Berger, a Carnegie-Princeton postdoctoral fellow, found one M-dwarf that doesn't conform.   view more (2007-12-06)

The importance of gene regulation for common human disease
A new study published in Nature Genetics on Sunday 16 September 2007 show that common, complex diseases are more likely to be due to genetic variation in regions that control activity of genes, rather than in the regions that specify the protein code.   view more (2007-09-17)

Conaway Lab Identifies Novel Mechanism for Regulation of Gene Expression
The Stowers Institute's Conaway Lab has demonstrated that an enzyme called Uch37 is kept in check when it is part of a human chromatin remodeling complex, INO80. The results were published in today's issue of Molecular Cell.    view more (2008-09-29)
