Sleeping beauty plays a significant role in identifying cancer genes

...elations typically of thousands of genes, and it's hard to know from the correlations which genes relate to cancer and which do not," said Largaespada. "By comparison, the jumping gene has inserted itself into cancer genes in the tumors we studied and thereby allows us to focus on smaller numbers of genes...

York scientists warn of dramatic impact of climate change on Africa

... of drought in the Sahel. Other areas particularly hard hit are eastern Africa and the south-west coast." Because of a scarcity of hard data, the team used a computer programme written by Dr Colin McClean, of York's Environment Departme...

Simple sea sponge helps scientists understand tissue rejection

...ant functions in cell-to-cell interactions, but is hard to study. The ultimate goal of this research is to provide insights into the machinery behind human tissue rejection and immune responses in hopes of someday being able to control these processes and save lives. ...

Researchers identify genes associated with lung transplant rejection

...But the problem with lung transplants is that it's hard to detect chronic rejection." Currently, he says, OB is best detected through a breathing test--but by the time the disease has a perceptible impact on the patient's ability to breathe, it's often too late to treat effectively. Caughey and his fello...

Several minute intermediate stage in virus-cell fusion discovered; opportunity for drug development

..." said Melikyan. "How this happens in real life is hard to say. "But our model," he added, "is likely to apply to any virus such as HIV that fuses with the cell membrane and shares the same fusion proteins, so it certainly provides a new target. Also, existing drugs can be re-evaluated to pinpoint at wha...

UQ researcher tracking key to healing the brain

... actually do - something that has been notoriously hard to do in the past. Dr Rietze is a finalist in the UQ Foundation Research Excellence Awards, to be announced tomorrow as a highlight of UQ Research Week 2005. He is working on a project with a novel approach to track neural stem cells in vivo. "Iden...

Toxic flood lifts lid on common urban pollution problem

... or rainwater that washes across streets and other hard surfaces in cities. Environmental engineering professor John Sansalone's perspective is especially relevant because it is based on field research in New Orleans and Baton Rouge, where he was a professor at Louisiana State University before taking a j...

High carbon dioxide levels spur Southern pines to grow more needles

...out a lot of leaf area, but then they get hit very hard under water stress because they have they extra leaf area they are no longer able to support," she said. Much of the leaf volume information for her study came after she and others weighed basketfuls of needles that had fallen into collection basket...

DNA from feathers tells tale of eagle fidelity

...e animals, she said. "Eastern imperial eagles are hard to catch, and individuals are difficult to tell apart," Rudnick said. "By performing genetic analysis on feathers collected at the site, we were able to track the presence or absence of individual birds over a six-year period." This kind of monitori...

Skull study sheds light on dinosaur diversity

...g habits. But without skulls to study, it has been hard to draw conclusions about how and what titanosaurs ate. With his work and that of researchers at the State University of New York, Stony Brook who announced the discovery of a complete titanosaur skeleton in 2001, sauropod specialists finally can st...

'Cookbook recipes' would cure disease with nontoxic DNA delivery systems

... their effectiveness in gene delivery, but this is hard and requires a lot of intuition," said Gerard Wong, a professor of materials science and engineering, physics, and bioengineering at the University of Illinois at Urbana-Champaign, and corresponding author of the paper. "By understanding some of the...

Infectious disease expert warns of spread of Rocky Mountain spotted fever

New tooth enamel dating technique could help identify disaster victims

...st Asia. "After a few days in the water, it's very hard to identify someone," he said. "You can't use (enamel dating) to identify a person ?that requires a DNA analysis ?but you can narrow down the number of people you need to look at from a list of missing people." Livermore officials are providing info...

Scientists find a maturity gene in fly

...its pupal case, which is like a cocoon but made of hard cuticle. Then ?nine days after the egg was laid ?the adult fly crawls out of the pupal case. Fruit flies have a two-month lifespan. "Teenagers are very pupal ?they go inside their shell and withdraw," Thummel says. "Steroid hormones take over your k...

Genetic variation alters response to common anti-clotting drug

...roper dose of warfarin can vary greatly and can be hard to predict. Some of this variability may boil down to a recently identified gene involved in blood clotting, according to a new study published in the June 2 issue of The New England Journal of Medicine. By looking at the genetic makeup of people on...

New technology shows our ancestors ate…everything!

...ry season, they may have to process something very hard or tough in order to survive." "For years, it's been a dream of many researchers interested in our lineage to obtain this kind of information," continued Teaford. "And the computer software is phenomenal, the heart and soul of this project. We now h...

What Makes The Brain Tick, Tick, Tick: Researchers Gaining New Insights Into Brain's Internal Clock

...nner. That's all interval timing, and in fact it's hard to find any complex behavioral process that timing isn't involved in." Deciphering the neural mechanisms of such clocks may be even more fundamental to understanding the brain than figuring out, for example, neural processing of spatial position and...

K-State professors discover enzyme responsible for creation of a beetle's hard shell
