Genome of deadly amoeba shows surprising complexity, evidence of lateral gene transfer

...rganisms. Detailing the first systematic study of relatively recent horizontal gene transfer into a protist, scientists report evidence in the DNA sequence that E. histolytica likely picked up a significant number of its metabolic genes from bacterial co-inhabitants of the human gut. Identification of these ge...

Antarctic ice shelf retreats happened before

...rctic Ice Sheet where scientists have found that a relatively warm current, Circumpolar Deep Water, is causing high melt rates on the underside of an ice shelf in Pine Island Bay*. The gradual removal of this ice shelf may be causing the glaciers inland to flow faster, which could lead to enhanced drainage of p...

Learning to fight an adversary that won't stay down

...he accompanying onset of resistance. "There are a relatively small number of antibiotics that have come out that are new, and some of them are very potent and act against most resistant strains," he says. "But the clinicians rightly try to keep these things in reserve for when they are really needed." ...

Yale Scientists Find MicroRNA Regulates Ras Cancer Gene

...ents surviving five years. The lungs, however, are relatively accessible for inhalation of potential gene therapy agents. "While this is not likely to cure the cancer," said Slack, "after diagnosis, gene therapy with let-7 may be a way to alleviate or slow it down." This work arose from Slack's basic research ...

Spider Venom Could Yield Eco-Friendly Insecticides

...g up in a fighting stance when provoked, making it relatively easy for researchers to aspirate venom directly from its fangs. Since Australian funnel-web spiders can live for more than five years in captivity, a small group of these spiders yields plenty of toxins for King's chemical analysis. Funnel-web spide...

Muscle-targeted gene therapy reverses rare muscular dystrophy in mice

...ins greatly decreased. Although Pompe disease is a relatively rare disease, it is but one of a group of related "lysosomal storage diseases," which in total occur in about one in 5,000 births. The current study is part of a large, collaborative effort at Duke University Medical Center to find an effective trea...

Researchers identify target for cancer drugs

... as it stays within the cell cytoplasm, it remains relatively inactive. That's because the tumor-suppressor protein PTEN keeps Akt in check by destroying lipids in the cell membrane that normally draw Akt to the surface. In a sense, PTEN keeps a leash on Akt and thus suppresses cell division. But when PTEN is ...

Protein Packages Found To Activate Genes; May Be What Regulates Development And Disease

...lusters, but HOX clusters in mice and humans boast relatively huge sections of chromatin completely covered with tags. This was not seen before by using standard techniques, or by studying one gene at a time. "Finding them was a complete surprise," Bernstein admits. HOX genes, as noted, play vital roles in emb...

Weill Cornell Research Reveals Secrets Of Trafficking Within Cells

...hip some kind of 'tipping point' occurs, so that a relatively small increase in clathrin kicks endocytosis into high gear." The study was conducted in fibroblasts, a kind of cell used in many cell-culture experiments. But Dr. Ryan said the findings have broad implications for cells throughout the body, includi...

First-ever Compounds To Target Only Metastatic Cells Are Highly Effective Against Breast, Prostate, And Colon Cancers

...t cell migration. Natural migrastatin's effect is relatively weak, but Dr. Huang suspected the molecule might be manipulated into something more potent. In collaboration with the laboratory of Dr. Samuel Danishefsky at the Memorial Sloan-Kettering Cancer Center, the team went to work creating what's called a "...

Same mutation aided evolution in many fish species, Stanford study finds

...same gene each time." Sticklebacks evolved from a relatively uniform marine population into today's broad spectrum of shapes and sizes when the last Ice Age ended roughly 10,000 years ago. Because ocean fish quickly evolved into such distinct populations when they colonized new freshwater lakes and streams, th...

Scientists discover unique microbe in California's largest lake

... or plant provided anutrient-rich environment with relatively high amounts of infraredlight; in the Salton Sea, the waters themselves create a comparableniche. Wood thinks that the high availability of nutrients in thewaters of the Salton Sea is what allowed the microbe to survive withoutits hosts in the saline...

NIAID Initiates Trial of Experimental Avian Flu Vaccine

...t Evaluation Units (VTEU). “While there have been relatively few cases worldwide of H5N1 avian influenza infection in humans, the public health community is concerned that the virus will develop the capability of efficiently spreading from human to human and thus create a risk for a worldwide pandemic,?says NI...

Ice core 'dipstick' indicates West Antarctic ice has thinned less than believed

...it appears the ice flowed vigorously despite being relatively thin. One major implication of the research, he said, is that it disputes the theory that West Antarctic ice streams retreated when the ice shelf did. In the last ice age, the ice streams near Siple Dome had to be roughly where they are now to keep ...

Falling ants glide back to trunk to avoid dangers of forest floor

...orizontally for long distances, the ants fall at a relatively high velocity, around 4 meters per second (12 feet per second), and approach the tree at a steep angle. This means they frequently bounce off the trunk, though, as Yanoviak initially noted, they just make a 180 degree turn and try again ?usually with...

Rats infected as newborns grew up vulnerable to memory problems during an immune challenge

... they get that second immune system challenge. The relatively uncommon one-two punch seems to cause the problem, although researchers don't know how long it lasts. Still, says Bilbo, "This may go far to explain some of the individual variability in disease susceptibility, other than genetic variation, in animal...

Genetically modified rice in China benefits farmers' health, study finds

Pesticide related illnesses Because there is a high incidence of pesticide-related illness in households of developing countries, includ...
