Genome analysis of “living fossil” sheds light on the evolution of plants Atmospheric oxygen really took off on our planet about 2.4 billion years ago during the Great Oxygenation Event. At this key juncture of our planet´s evolution, species had either to learn to cope with this poison that was produced by photosynthesizing cyanobacteria or they went extinct. It now seems strange to think that the gas that sustains much of modern life had such a distasteful beginning....

Organic farms produce strawberries with fewer malformations and a higher proportion of fully pollinated berries relative to conventional forms, according to a Feb. 15 report in the open access journal PLoS ONE. The study, led by Georg Andersson of Lund University in Sweden, investigated the effect of organic farming compared to conventional. They found that the pollination success increased greatly with organic farming, and speculate that this effect may be due to an increase in insect...

Scientists Discover Key to Creating 'Supersoldier' Ants
2012-01-06 13:55:10

According to a new report published in the journal Science, an international team of researchers has found a way to program ants to become so-called “supersoldiers”. And what´s even more exciting, say researchers, the hidden switch for unlocking the trait in ants might also be present in a number of other species. All ant colonies, like those of their fellow Hymenoptera wasps and bees, are organized into various classes known as ℠castes´, which include,...

Invading Species Threaten Texas Gulf Coast
2011-12-29 05:52:05

The Asian Tiger Prawn, an invasive species in the Gulf of Mexico that can grow nearly a foot long and threatens native wild stocks, has been found on the Texas coast. The tiger prawns, native to the western Pacific, have been spreading along the Gulf Coast since 2006 and their numbers have increased this year. Shrimpers pulled the first one from Texas waters in June. So far shrimpers harvested three in Aransas Bay, one from Sabine Lake at the Louisiana Border and one from open waters about...

A 125-year debate on how nitrogen-fixing bacteria are able to breach the cell walls of legumes has been settled A 125-year debate on how nitrogen-fixing bacteria are able to breach the cell walls of legumes has been settled. A paper to be published on Monday by John Innes Centre scientists reports that plants themselves allow bacteria in. Once inside the right cells, these bacteria take nitrogen from the air and supply it to legumes in a form they can use, ammonia. Whether the bacteria...

Keep Arms And Legs Hairy To Keep Bed Bugs Away
2011-12-15 12:21:04

Looking to avoid confrontations with bed bugs? You will be better off not shaving your legs according to researchers in the UK. Twenty-nine volunteers bravely tested the theory by Michael Siva-Jothy, from Sheffield University´s Department of Animal and Plant Sciences, BBC News is reporting. Siva-Jothy found that more layers of both long and short body hair near the surface appeared to work as a deterrent to the blood-sucking insects, with the finer hairs acting as an early warning...

Worker ants from a particular species of African ants have potent venom that can paralyze and kill termites from a distance, according to a study published Dec. 14 in the online journal PLoS ONE. The research, conducted using a species called Crematogaster striatula, showed that chemicals the worker ants emit from their stinger have three functions: they attract nearby nestmates; repel alien ants; and paralyze and kill termites. While the first two effects require the ants to come into...

Worms infecting fish grow 4 times faster at higher temperatures and manipulate the behavior of fish Parasitic worms that infect fish, and have a devastating effect on fish reproduction, grow four times faster at higher temperatures — providing some of the first evidence that global warming affects the interactions between parasites and their hosts. The study from the University of Leicester revealed that global warming had the potential to change the balance between parasite and...

Sebae Clownfish, Amphiprion sebae
2013-02-17 07:52:18

Image Credit: Miles Wu/Wikipedia (CC BY-SA 2.0) The sabae clownfish is a very rare species in the wild and is aggressive, especially as it matures. It is found in the northern Indian Ocean around India, Sri Lanka, Arabian Peninsula, Andaman Islands, Sumatra, Indonesia, and the Maldive Islands. This fish inhabits lagoons and coastal waters around reefs, at a depth range of 6 - 75 feet. This species of fish is the most popular fish for home aquariums. The body of the sabae clownfish is...

Saddleback Clownfish, Amphiprion polymnus

Image Caption: Amphiprion polymnus at Tasik Ria House reef, North Sulawesi, Indonesia. Credit: Jens Peterson/Wikipedia (CC BY-SA 3.0) Saddleback clownfish are found in harbors and lagoons with a soft or sandy bottom, around reefs at depths from 6 - 90 feet. This fish is native to the Western Pacific, around China, Viet Nam, Gulf of Thailand, Indonesia, Philippines, northern Australia, New Guinea, New Britain, and the Solomon Islands. The body of the saddleback clownfish ranges in color...

Convict Blenny, Pholidichthys leucotaenia
2013-01-03 15:48:38

The convict blenny lives in tunnels around coastal reefs and in shallow lagoons of the Western South Pacific, mainly from the Philippines to the Solomon Islands. The young of this fish will often swim in schools around the reef heads and ledges so tightly packed together they will look like one organism. This species, sometimes called a blenny and sometimes called a goby, actually it is neither. It is in a classification alone with one other species called a worm blenny. The convict blenny...

The Polydnaviruses (PDV) are a family of insect viruses that contain two genera: Ichnoviruses (IV) and Bracoviruses (BV). The ichnoviruses occur in ichneumonid wasps and bracoviruses in braconid wasps. The virus is composed of multiple segments of double-stranded superhelical DNA packaged in capsid proteins and a double layer or single layer envelope. The full genome of the virus is integrated into the genome of the wasps and the virus only replicates in specific cells in the female...

The ants, one of the most successful groups of insects, are of particular interest because they form advanced colonies, and can constitute up to 15 percent of the total animal biomass of a tropical rainforest. They belong to the order Hymenoptera and are close relatives of the vespoid wasps. Ants appear in amber, found in central New Jersey, believed to be from the Cretaceous period. It is thought that they evolved from the wasps that had appeared during the Jurassic period. They are...
