Virus named as possible factor in honey bee disorder
A comparison of healthy and unhealthy bee colonies points to a virus contributing to Colony Collapse Disorder (CCD), according to a report being published by the journal Science, at the Science Express web site, on 06 September. Science is published by AAAS, the nonprofit science society. view more (2007-09-07)
'Godmother' ant uses Mob tactics to rub out rivals
Researchers at the University of Sheffield and the University of Keele have discovered that Dinoponera quadriceps ants, known as Dinosaur ants, and the Mafia have something in common. Both have dominant leaders who give rivals a "kiss of death", as a signal for their 'mob' to punish the offender. The alpha female in a colony of Dinosaur... view more... (2002-09-02)
Worker ants store fat to share with colony members during times of need
In a fascinating new study from the September/October 2006 issue of Physiological and Biochemical Zoology, Daniel A. Hahn (University of Florida) explores the ability of ants to store excess fat and pass it to colony members through lipid-rich oral secretions or unfertilized eggs. view more (2006-07-27)
Orphan army ants join nearby colonies
Colonies of army ants, whose long columns and marauding habits are the stuff of natural-history legend, are usually antagonistic to each other, attacking soldiers from rival colonies in border disputes that keep the colonies separate. view more (2009-11-05)
Digital Ant Colony System
Whoever thinks that ants are only erratic little beings, whose incessant wanderings are pointless or obey no kind of universal order, is very much mistaken. Their society is so organized and complex that it is already being used as a model for the creation of algorithms, adaptable to a variety of scientific areas. Inspired by the work of Chialvo... view more... (2002-09-30)
Ancient neutrinos could put string theory and quantum loop gravity to the test
Tiny but ageing neutrinos can be used to test the very foundations of quantum theory at unprecedented cosmological time scales. view more (2005-10-14)
Satellite spies on doomed Antarctic ice shelf
Satellite images have revealed the collapse of Larsen B ice shelf on the Antarctic Peninsula fulfilling predictions made by British Antarctic Survey (BAS) scientists. The collapse of the 3250 km2 ice shelf is the latest drama in a region of Antarctica that has experienced unprecedented warming over the last 50 years. Earlier this month Ted Scambos... view more...

Deadly mine 'bump' was recorded as seismic event
The University of Utah Seismograph Stations recorded a magnitude-1.6 seismic event at the time of a Thursday, Aug. 16 "bump" that killed and injured rescuers at a Utah coal mine where six miners were trapped by an Aug. 6 collapse. view more (2007-08-20)
Climate change following collapse of the Maya empire
Researchers from the University of Amsterdam have demonstrated that the climate in South Mexico changed following the collapse of the Maya empire. From preserved pollen grains the paleoecologists could deduce that the climate quickly became dryer. The climate becoming dryer, explains the decrease in the population following the collapse of the... view more... (2002-01-29)
Stratified seawater disrupts the transport of imposex substances
Researchers from the University of Amsterdam have demonstrated that the climate in South Mexico changed following the collapse of the Maya empire. From preserved pollen grains the paleoecologists could deduce that the climate quickly became dryer. The climate becoming dryer, explains the decrease in the population following the collapse of the... view more... (2002-01-24)
Algae's Protein "Tails" Create Motion — and Aid Munching
When single-celled organisms such as sperm crack their whip-like appendages called flagella, the beating sets them in motion. But in certain colonies of green algae, flagella also boost nutrient uptake, according to surprising new research. view more (2006-05-30)
Are sacrificial bacteria altruistic or just unlucky?
An investigation of the genes that govern spore formation in the bacteria B. subtilis shows that chance plays a significant role in determining which of the microbes sacrifice themselves for the colony and which go on to form spores. view more (2008-04-16)
Researchers distinguish waves from mine collapses from other seismic activities
Researchers have devised a technology that can distinguish mine collapses from other seismic activity. view more (2008-07-11)
Predicting Volcanic Eruptions
The weather forecast could help predict volcanic eruptions, according to new research from the University of East Anglia (UEA). Scientists from UEA`s School of Environmental Sciences found that intense rainfall can trigger volcanic dome collapse - a particular type of eruption that occurs when a build-up of molten rock inside the side of the... view more...

Finding of genetic region controlling cardiovascular sensitivity to anesthetic propofol
Researchers at The Medical College of Wisconsin in Milwaukee have identified the genetic region in rats responsible for cardiovascular collapse during anesthesia. view more (2009-09-11)
Flexible genes allow ants to change destiny
The discovery of a flexible genetic coding in leaf-cutting ants sheds new light on how one of nature's ultimate self-organising species breeds optimum numbers of each worker type to ensure the smooth running of the colony. view more (2007-05-25)
Honeybee dance breaks down cultural barrier
Asian and European honeybees can learn to understand one another's dance languages despite having evolved different forms of communication, an international research team has shown for the first time. The findings are published this week in the journal PLoS ONE. view more (2008-06-04)
Homebound termites answer 150-year-old evolution question
Staying at home may have given the very first termite youngsters the best opportunity to rule the colony when their parents were killed by their neighbors. view more (2009-10-06)
How To Make Use Of Hydroids Behaviour
All organisms own somewhat puzzling integrity - functions of their parts are matched, growth and development are harmonic, movements are coordinated. In most cases, this integrity is provided by central neural system and humoral regulation. However, sometimes both CNS and humoral regulating system are absent. Ants colony works in amazing... view more... (2002-06-07)
Newly Compiled Online Bee Checklist Allows Biologists To Link Important Information About All Bee Species
n time for National Pollinator Week, June 22 through June 28, biologists have completed an online effort to compile a world checklist of bees. They have identified nearly 19,500 bee species worldwide, about 2,000 more than previously estimated. view more (2008-06-19)
