Deep treasure to be found in Oculina Bank

...ed encouraging signs that fish populations in this section are slowly but surely increasing. In coming years, researchers hope to see populations of snappers and groupers recovering enough to again form large breeding aggregations in the area. "We need to establish a statistically and scientifically sound ...

Plant defenses prompt bacterial countermeasure in the form of 'island' DNA excision

...at the pathogenic bacteria essentially kicks out a section of its genome when it senses that its presence has been detected by the plant's defense system. Excising this so-called "genomic island" eliminates production of the bacterial protein detected by the plant and allows a more stealthy ?and successful ?...

New understanding of regeneration gained by Forsyth scientists

...rocess. When the worms are cut in half, the bottom section of the worm grows a head and the upper section a tail. Scientists have suspected that the ability of previously adjacent cells (on either side of ...

Looking for the genes that affect a person's level of response to alcohol

...search had indicated a potential link between this section of this chromosome and a person's alcohol response. "Researchers in San Francisco had previously carried out some research on worms," explained Schuckit, "finding that those worms with a mutation in that gene were fairly insensitive to alcohol. We...

Novel enzyme offers new look at gene regulation

...ential to remove trimethyl groups. JmjC is only a section of the entire JHDM1A protein, but is required for ...ving histone methyl groups. Importantly, the JmjC section of JHDM1A, or "JmjC domain," can be found in other proteins, even when the proteins share little els...

Students discover 11,000 year old remains of Irish Elk

... "I just scraped the surface of the fallen cliff section ?which was in a block that had recently slid down the cliff ?and uncovered an orange streak which turned out to be an antler." As the block was in danger of imminent collapse, which would have crushed the antler, Dr Davey arranged for a team to rem...

Argonne researchers confirm lead in Beethoven's illness

...amined. Both bone fragments were from the parietal section ?the top ?of the skull. "The testing indicated large amounts of lead in the Beethoven bone sample, compared to the control," said Bill Walsh, chief scientist at the Pfeiffer Treatment Center in Warrenville, Ill., and director of the Beethoven Resear...

Amazon rainforest greens up in the dry season

... of Arizona in Tucson. "What we found for a large section of the Amazon is the opposite. As soon as the rains stop and you start to enter a dry period, the Amazon becomes alive. New leaves spring out, there's a flush of green growth and the greening continues as the dry season progresses." The finding hold...

Stem cell study for patients with heart attack damage seeks to regenerate heart muscle

... intravenously followed the signals to the injured section of the heart and aided in repair. These cells have also been studied for different diseases and have been shown to follow inflammatory signals to various areas of the body to aid in repair. The delivered cells are expected to respond to the body's o...

Genetically engineered mosquitoes show resistance to dengue fever virus

...p the process. They accomplished this by cloning a section of the virus' RNA and injected two inverse copies of it into mosquito embryos. The copies formed a double-stranded RNA, which, as expected, bound with dicer-2 and was chopped up. The virus never had the opportunity to replicate. As a result, they cou...

Biology Direct considers original research articles, hypotheses, and reviews and will eventually cover the full spectrum of biology. Biology Direct is led by Editors-in-Chief David J Lipman, Director of the National Center Biotechn...

Stable polymer nanotubes may have a biotech future

...ical was added to break bonds between atoms in one section of the polymers and induce new bonds to form between the two different sections, forming a rigid "cross-linked" membrane. The nanotubes are then snipped free from the parent cell with an "optical scalpel" (highly focused ultraviolet laser pulse). The...

Salmonella bacteria use RNA to assess and adjust magnesium levels

New method for identifying microbes

...ell. "Sequencing is expensive, so the shorter the section you can sequence and still get useful information, the better," van der Lelie said. "In fact, because these tags are so short, we 'glue' 10 to 30 of them together to sequence all at one time, making this a highly efficient, cost-effective technique."...

First surveys of Tanzanian mountains reveal 160+ animal species, including new & endemic

"Surveying just one section of the Eastern Arc, we discovered a little frog no one knew existed," said Nike Doggart, lead author of the article and Technical Advisor, Tanzania Forest Conservation Group. "Imagine what other wildlife we may discover if we can help preserve the wh...

Mechanism identified for promising neurological drug

... paper appears in the current online Early Edition section of the Proceedings of the National Academy of Sciences. According to Swanson, the finding indicates that researchers need to look more closely at minocycline's potential effects on cell health, both positive and negative, as well as its potentially ...

U of M researchers discover genetic key to treating deadly fungal infections

...s the effects of antifungal drugs by duplicating a section of one of its chromosomes. Candida albicans, a type of yeast present in 80 percent of humans, is usually harmless. In otherwise healthy people, it can cause mild oral and vaginal infections (candiasis or thrush) that are easily treated. But in peo...

Flick of whiskers helps tease out brain's 'shadow' signaling system

The chemical step is a sign that the cell has been triggered in some way and is ready to send out a signal itself. While it's been shown before that astrocytes can become activated under extreme conditions i...
