...d and sulfur-rich environment. "We really want to try and understand the plumbing system for this spring and where all this sulfur is coming from," Beauchamp said. "This is a very unusual feature on the earth's surface and it's an extreme ecosystem that could be a good model for how life first begins in...

Scientists tie several cancers to common 'oncogene engine'

...erapies that may be effective against one tumor to try to treat other tumors, said Fisher. "In the longer term, the focus is on targeting the real culprit ?and that is the MiT transcription factors or their targets. There is lots of excitement, and I believe that is the way to really nail these tumors." ...

Biologists find regions of rice domestication

...wn many generations, Schaal said. "We're going to try to find out how landrace varieties change after domestication," Schaal said. "These landraces are ancient varieties, which are high in genetic diversity, thus valuable to breeders looking for new traits." ...

Species unique to tidal marshes face threats

...oauthors argue for an expanded research program to try to understand how species will respond to these threats. BioScience publishes commentary and peer-reviewed articles covering a wide range of biological fields, with a focus on Organisms from Molecules to the Environment. The journal has been publish...

Diabetes research takes wing thanks to long-lived fruit fly

...rs he has worked with Jasper, using fruit flies to try to unravel the molecular signals that enable cancer cells to grow. Jasper earned his doctoral degree under Bohmann's guidance in 2002 and is now an assistant professor of Biology. Bohmann initially studied cancer in human cells, then switched to stu...

Trials for new drug to overcome HIV

...dition to their standard drugs. There are plans to try the drug along with new regimes tailored to individual patients, though Allaway warns that larger trials are needed and PA-457 will not reach the market until 2009 at the earliest. Other HIV researchers are also enthusiastic about PA-457. "It's a tr...

'Smart' genetic therapy helps the body to heal itself

...s derived from rat embryos. "The next step was to try this therapy in patients", said Professor Wirth. "In a first pilot trial, we enrolled ten parents of SMA patients who were treated with valproate for four months. We saw that valproate significantly increased SMN levels in blood. Based on this ...

Scientists use gene signatures to match cancer and other diseases with potentially effective drugs

..., adding that a clinical trial is being planned to try rapamycin in children who have had recurrences of initially successfully treated ALL. Moreover, the comparison of gene signatures revealed that rapamycin's effectiveness was due in part to its action on a molecule that causes cancer cells to self-d...

Immune cell communication key to hunting viruses, Jefferson immunologists show

...close to each other. "We've shown that when we try to mimic the positioning of MHC protein on quantum dots, which we believe is similar to what it is on the cell membrane, we have this very strong binding. An important message is that a single virus-MHC complex recognized in the context of self-MHC c...

AIDS study challenges conventional treatment guidelines for HIV patients

...l set of laboratory results and the clinician must try to predict how quickly that person's CD4 cell count will reach the danger level at which treatment for HIV becomes most critical. Current clinical practice, based on previous work from other groups, is to focus on both the current CD4 count and the v...

P(acman) takes a bite out of deciphering Drosophila DNA

...s breed flies that lack a particular gene and then try to put that gene back into the fly, it inserts itself randomly into the genetic blueprint. In some cases, it makes too much protein, and in others, too little. In other instances, it may disrupt the message from another gene. “You are really ...

'Mindless autopilot' drives people to underestimate food decisions

... in the first place," said Wansink. "Rather than try to overly obsess about our food decisions, it's better to change the environment so that it works for us rather than against us, making it easier to make decisions to eat less," suggested Wansink. Tips to prevent holiday overeating To turn...

New evidence of early horse domestication

...ng through fall. "No one in their right mind would try to milk a wild mare," said Olsen. There is also evidence that the Botai were carrying a lot of heavy material, like rocks and large skulls, over long distances. That is a lot more practical and explicable if they used pack horses. Later people of...

Individual mutations might disrupt the work of a cascade of genes that cooperate to construct certain nerves or sections of the inner ear that sense sound; that stimulation i...
