Biology articlesAnt invaders eat the natives, then move down the food chain
The Argentine ant, Linepithema humile, is one of the most successful invasive species in the world, having colonized parts of five continents in addition to its native range in South America. A new study sheds light on the secrets of its success.
'Jekyll and hyde' bacteria offer pest control hope
As a step towards designing tomorrow's super-fast optical communications networks, a Duke University-led research team has demonstrated a way to transfer encoded information from a laser beam to sound waves and then back to light waves again.
Seabed microbe study leads to low-cost power, light for the poor
A Harvard biology professor's fascination with seafloor microbes has led to the development of a revolutionary, low-cost power system consuming garbage, compost, and other waste that could provide light for the developing world.
Adult male chimpanzees don't stray far from the home
When it comes to choosing a place to live, male chimpanzees in the wild don't stray far from home, according to a new report in the Dec. 27th Current Biology, a publication of Cell Press. The researchers found that adult male chimps out on their own tend to follow in their mother's footsteps, spending their days in the same familiar haunts where they grew up. Male chimpanzees are generally very social, but how they use space when they are alone might be critical to their survival, the researchers said.
Why diving marine mammals resist brain damage from low oxygen
No human can survive longer than a few minutes underwater, and even a well-trained Olympic swimmer needs frequent gulps of air. Our brains need a constant supply of oxygen, particularly during exercise.
Research on how plants transport sugars could be of critical importance in era of global warming
How do many plants ship sugars from their leaves to flowers, roots, fruits and other parts of their structure? Using genetic engineering techniques, Cornell researchers have finally proven a long-standing theory of how this occurs.
Study maps life in extreme environments, creating potential for molecular bioengineering and dynamical models of cells
A team of biologists have developed a model mapping the control circuit governing a whole free living organism. This is an important milestone for the new field of systems biology and will allow the researchers to model how the organism adapts over time in response to its environment.
2 explosive evolutionary events shaped early history of multicellular life
Scientists have known for some time that most major groups of complex animals appeared in the fossils record during the Cambrian Explosion, a seemingly rapid evolutionary event that occurred 542 million years ago. Now Virginia Tech paleontologists, using rigorous analytical methods, have identified another explosive evolutionary event that occurred about 33 million years earlier among macroscopic life forms unrelated to the Cambrian animals. They dubbed this earlier event the "Avalon Explosion."
Life at the jolt
Researchers at the Biodesign Institute are using the tiniest organisms on the planet 'bacteria' as a viable option to make electricity. In a new study featured in the journal Biotechnology and Bioengineering, lead author Andrew Kato Marcus and colleagues Cesar Torres and Bruce Rittmann have gained critical insights that may lead to commercialization of a promising microbial fuel cell (MFC) technology.
Youngsters prefer a home like mom's
When young mice leave their mothers' homes, they choose to live in places much like the ones where they were raised, according to research done at UC Davis.
A helping hand from the grandparents
A team of scientists led by the University of East Anglia has discovered the existence of 'grandparent' helpers in the Seychelles warbler – the first time this behaviour, which rarely occurs except in humans, has been observed in birds.
Researchers develop method for production of more efficient biofuels
Researchers at the UCLA Henry Samueli School of Engineering and Applied Science have developed a new method for producing next-generation biofuels by genetically modifying Escherichia coli bacteria to be an efficient biofuel synthesizer. The method could lead to mass production of these biofuels.
Life's six-legged survivors evolutionary study shows beetles are in it for the long run
Most modern-day groups of beetles have been around since the time of the dinosaurs and have been diversifying ever since.
Down to earth remedies for chimps
The deliberate ingestion of soil, or 'geophagy', has important health benefits for chimpanzees, according to Sabrina Krief and her colleagues from the Muséum National d'Histoire Naturelle in Paris, France.
Protein in human hair shows promise for regenerating nerves
A protein found in human hair shows promise for promoting the regeneration of nerve tissue and could lead to a new treatment option when nerves are cut or crushed from trauma.
Scientists find missing evolutionary link using tiny fungus crystal
The crystal structure of a molecule from a primitive fungus has served as a time machine to show researchers more about the evolution of life from the simple to the complex.
Mit team discovers bacterial surprise
A team of MIT researchers and others has discovered that bacteria employ a type of DNA modification never before seen in nature. -FULL TEXT:
Researchers trigger insulin production in diabetic mice
If the human body were a stage, then proteins would rank among the lead actors in the play we call "Life."
Why it pays to be choosy
Cooperative behaviour is common in many species, including humans. Given that cooperative individuals can often be exploited, it is not immediately clear why such behaviour has evolved.
New genus of self-destructive palm found in Madagascar
A gigantic palm that flowers itself to death and exists as part of an entirely unique genus has been discovered in Madagascar. The mystery palm has a huge trunk which towers over 18m high and fan leaves which are 5m in diameter -among the largest known in flowering plants. This is the most massive palm ever to be found in Madagascar.
