The evolution of food plants: Genetic control of grass flower architecture
Scientists are interested in understanding genetic control of grass inflorescence architecture because seeds of cereal grasses (e.g. rice, wheat, maize) provide most of the world's food.   view more (2006-01-23)

UGA researchers propose new hypothesis on the evolution of hot springs microorganisms
Since their discovery in the late 1970s, microorganisms known as archaea have fascinated scientists with their ability to thrive where no other life can — in conditions that are extremely hot, acidic or salty.   view more (2006-06-06)

Life Cycle of Operons Yields New Look at Bacterial Genetics
In a breakthrough that will immediately benefit biologists who study bacteria, and could in the future have bearing on the advancement of synthetic biology, a team of researchers has determined the life cycle of operons, small groups of genes with related functions that are co-transcribed in a... view more (2006-07-06)

Startling results from new biomedical research international conference will smooth path to the market place
Researchers have discovered how to convert liver cells of mice into pancreatic cells using a single injection. This may eventually lead to a cure for diabetes. Dr. James Mittra, one of the organisers of an international conference in Edinburgh on the Evolution of the Life Science Industries asks,... view more (2005-01-27)

Bacteria reveal secret of adaptation at Evolution Canyon
Bacteria living on opposite sides of a canyon have evolved to cope with different temperatures by altering the make-up of their 'skin', or cell membranes. Scientists have found that bacteria change these complex and important structures to adapt to different temperatures by looking at the... view more (2008-07-28)

HOW TREES CHANGED THE WORLD
Before 380 million years (Ma) ago, the continents had only patches of mosses and algae with no tree cover. The effect of the evolution of trees (large vascular plants with deep, extensive roots) changed the world for ever, according to Dr Robert Berner (Yale University). He presents his findings at... view more (2001-06-21)

Evolutionary shifts in olfactory sensitivities in fruit flies
How do an animal's senses change as it evolves to occupy a new ecological niche? By comparing the olfactory system of the fruit fly Drosophila melanogaster, which feeds from multiple fruit types, with that of its sibling species D. sechellia, a specialist particularly drawn to a single fruit type.   view more (2006-01-10)

Ancient protein offers clues to killer condition
More than 600 million years of evolution has taken two unlikely distant cousins - turkeys and scallops - down very different physical paths from a common ancestor. But University of Leeds researchers have found that a motor protein, myosin 2, remains structurally identical in both creatures.   view more (2008-05-13)

Does life exist on other planets?
Recent research argues that an atmosphere rich in oxygen is the most likely source of energy for complex life to exist anywhere in the Universe, thereby limiting the number of places life may exist.   view more (2005-06-20)

Islands spark accelerated evolution
The notion of islands as natural test beds of evolution is nearly as old as the theory itself. The restricted scale, isolation, and sharp boundaries of islands create unique selective pressures, often to dramatic effect.   view more (2006-09-12)

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... view more (2008-11-20)

Investigating the invisible life in our environment
Microorganisms make up more than a third of the Earth's biomass. They are found in water, on land and even in our bodies, recycling nutrients, influencing the planet's climate or causing diseases.   view more (2007-02-02)

How Life Originated In Space
Life originated on the Earth more than 3.5 billion years ago. However, the scientists are still disputing over the possible sources of the life origin. The matter is that life on our planet evolved from the molecular level to the level of bacteria organisms within 0.5 - 1 billion years, this period... view more (2002-04-12)

Study reveals surprising details of the evolution of protein translation
A new study of transfer RNA, a molecule that delivers amino acids to the protein-building machinery of the cell, challenges long-held ideas about the evolutionary history of protein synthesis.   view more (2008-08-13)

Scientists force viruses to evolve as better delivery vehicles for gene therapy
Viruses and humans have evolved together over millions of years in a game of one-upmanship that, often as not, left humans sick or worse.   view more (2006-02-08)

EU-funded project to grow first artificial society
A EUR1.55 million project funded by the European Union's Sixth Framework Programme to grow the first society based on artificial, computer-based beings, much like characters in popular computer games such as SIMS, was officially launched on Wednesday during the AISB2005 convention at the University... view more (2005-04-14)

Evolutionary scrap-heap challenge: Antifreeze fish make sense out of junk DNA
Scientists at the University of Illinois have discovered an antifreeze-protein gene in cod that has evolved from non-coding or 'junk' DNA.   view more (2006-04-04)

Caltech astronomers describe the bar scene at the beginning of the universe
Bars abound in spiral galaxies today, but this was not always the case. A group of 16 astronomers, led by Kartik Sheth of NASA's Spitzer Science Center at the California Institute of Technology, has found that bars tripled in number over the past seven billion years, indicating that spiral galaxies... view more (2008-07-30)

Parasites might spur evolution of strange amphibian breeding habits
Parasites can decimate amphibian populations, but one University of Georgia researcher believes they might also play a role in spurring the evolution of new and sometimes bizarre breeding strategies.   view more (2007-11-15)

Evolutionary harmony for stinkbugs and their gut bacteria: A perfect match
With some 1 million species and counting, insects may be the most abundant class of animals living today. Their protective exoskeleton, prolific reproductive rate, and wings help their cause, as do the symbiotic bacteria that inhabit their cells, gut, or body cavity.   view more (2006-10-10)

Origins of nervous system found in genes of sea sponge
Scientists at the University of California, Santa Barbara have discovered significant clues to the evolutionary origins of the nervous system by studying the genome of a sea sponge, a member of a group considered to be among the most ancient of all animals.   view more (2007-06-06)

MicroRNAs have shaped the evolution of the majority of mammalian genes
RNA continues to shed its reputation as DNA's faithful sidekick. Now, researchers in the lab of Whitehead Institute Member David Bartel have found that a class of small RNAs called microRNAs influence the evolution of genes far more widely than previous research had indicated.   view more (2005-11-30)

UK Astronomers Survey Galactic Graveyard
An unprecedented source of planetary nebulae, the disk-like relics of elderly, dying stars, has been discovered in the southern part of our Milky Way galaxy. With about 1000 planetary nebulae found so far and many more still to be discovered, the number of aged stars in their death throes revealed... view more (2002-04-07)

Sperm proteome gives "tantalising glimpse" towards the origin of sex
The first ever catalogue of the different types of proteins found in sperm could help reveal the origins of sex and explain some of the mysteries of infertility, say scientists.   view more (2006-11-13)

St. Jude conducts first large-scale bird flu genome study
Unique resources at St. Jude Children's Research Hospital let researchers generate a "gold mine" of data to track evolution of bird flu virus genes and understand how they cooperate to cause disease.   view more (2006-01-27)
