Timing is everything: First step in protein building revealed

...o shifts in thecolor given off. First, there was a slight shift, indicating a smallchange in the distance between eIF1 and its relative, and then a muchlarger shift, indicating a much bigger separation.To prove eIF1 was being released from the ribosome complex, theresearchers examined how fast the pieces of...

New RNA polymerase discovered in plants

... consequences. The plants survived, but there were slight delays in flowering and some strange floral defects. The plants were having trouble with organ identity ?stamens tried to turn into petals, for instance. Our first hypothesis was that the fourth polymerase was involved with what are known as micro RN...

How the environment could be damaging men's reproductive health

...ribution of sex chromosomes in sperm, leading to a slight increase in the number of sperm bearing the Y chromosome Aleksander Giwercman, professor of andrology at the Scanian Andrology Centre, Fertility Centre, Malmö University Hospital, Lund University, Sweden, and his colleagues looked at the effect of t...

HIV vaccine trial breaks ground for future research

...er incidence of HIV infection. Citing the possible slight vaccine efficacy for non-white and high-risk participants of the trial, they urged that future vaccines be studied in a wide range of racial, ethnic, and diverse risk-level groups. They concluded that the landmark study will inform future studies, an...

Biomarkers isolated from saliva successfully predict oral and breast cancer

...ng. "For oral cancer, salivary transcriptome has a slight edge of that of serum transcriptome analysis." Future research not only will involve a larger sample of cancer patients to refine prediction models, but also will include studies involving precancers and other difficult to detect cancers such as ova...

Tamoxifen-like drug suggests new ways to selectively block estrogen

Depression gene may weaken mood-regulating circuit

...e focused on possible functional consequences of a slight variation in its DNA sequence across individuals. Everyone inherits two copies of the gene, one from each parent, which comes in two common versions: short and long. The short version makes less protein, resulting in less recycling, increased levels ...

Scientists focus on 'dwarf eye'

...lex growth of the human eye. All human eyes have a slight degree of farsightedness at birth. As the child grows and gains more visual experience, the eye adjusts its focus by growing, which changes the distance between the lens and the retina, the light-detecting layer of cells at the back of the eye. Once ...

Researchers Create DNA-Based Sensors for Nano-Tongues and Nano-Noses

...sensor binds to a target molecule, there will be a slight change in the electric charge near the nanotube," Johnson said. "The nanotube will then pick up on that change, turning it into an electric signal that can then be reported." According to Johnson, an array of 100 sensors with different response char...

Researchers find how some antibiotics kill bacteria

... This new knowledge may help drug developers make slight changes to these antibiotics to make them more effective against drug-resistant strains of bacteria, said Irina Artsimovitch, a study co-author and an assistant professor of microbiology at Ohio State University. The antibiotics studied belong to th...

North & South American researchers find architectural abnormalities in T. cruzi ribosome

...osomes of different eukaryotic organisms have only slight differences in their peripheral elements, such as specialized tools to send newly formed proteins into or through membranes. If anything, Frank expected the trypanosome's ribosome might be missing some elements, because of its sheltered life within h...

Number Of Babies Born Prematurely Nears Historic Half Million Mark In U.S.

... it has increased every year since then except for slight dips in 1992 and 2000. "Prematurity is the number one killer of newborns. We see from these latest statistics that the prematurity crisis in this country continues to intensify, and the aftermath of Hurricane Katrina will only make it worse, " said...

Scientists unpick genetics of first 15 minutes of life

...etically complete the beginning of a new life. "A slight mutation in the HIRA gene means that life does not even get started. "Amazingly we still know relatively little about the structure of sperm DNA and the genetic processes involved in the most crucial early phases of reproduction." Because of the pa...

Novel enzyme offers new look at gene regulation

...e they are so intimately associated with DNA, even slight chemical alterations of histones can have profound effects on nearby genes. Depending on the precise location and how many methyl groups are added, their presence can either switch affected genes on or off. The first enzyme to remove methyl groups f...

Mice studies illustrate potential of chimp/human antibodies to protect against smallpox

...8AL two days after virus exposure experienced only slight weight loss followed by rapid recovery. Conversely, all five of the mice that received 5 mg of VIG 48 hours after virus exposure experienced much greater weight loss than those that received the hybrid antibody. "This study demonstrated that the hy...

DNA conclusive yet still controversial, Carnegie Mellon professor says

...it was about 1 in 26 quintillion, a probability so slight it needn't be shared with juries, Roeder said. "The jury can't handle such small numbers. We would do them a service to simply tell them it matches or it doesn't match," Roeder said. Roeder began her career as a biologist, and much of her current r...

Warming trend may contribute to malaria's rise

...model, Pascual and coworkers showed that even such slight warming could have biological consequences. "We showed that a small increase in temperature can lead to a much larger increase in the abundance of mosquitoes," she said. "And because mosquito abundance is generally quite low in these highland region...

Amazon rainforest greens up in the dry season

...f the humongous amount of carbon it stores. A very slight change in the forest's activity will make a tremendous change in the global carbon cycle." Saleska and his colleagues and other research teams had conducted studies at local sites in the Amazon that suggested the intact rainforest grows more during ...

Researchers develop portable 'vein finder' for faster, more accurate injections

... the ultrasonic waves into the patient's skin at a slight angle. The device can determine the direction of blood flow to distinguish arteries (which carry blood away from the heart) from veins (which carry blood to the heart). Once the device detects a vein, an alarm is triggered, and medics insert the need...
