Nano-Probes Allow an Inside Look at Cell Nuclei

...ycle control. The long-lived probes may also allow researchers to track the effectiveness of disease-fighting drugs that target these processes. "We could determine whether a drug has arrived where it is supposed to, and if it is having the desired impact," says Chen. The first enduring look into the secret li...

New studies suggest airborne SARS transmission is possible

...ed in the air in one of the four rooms tested. The researchers also detected virus in four of 85 surface samples taken from frequently touched surfaces, highlighting the importance of strict adherence to infection control precautions to prevent SARS coronavirus transmission in the health care setting. In the Ho...

Circles Of DNA Might Help Predict Success Of Stem Cell Transplantation

...ors who provided stem cells to their siblings. The researchers also tested 244 samples from 26 of the recipients themselves. The recipients had been treated for either white cell cancers (e.g., acute lymphoblastic leukemia) or red cell diseases (e.g., sickle cell disease). Because blood from the normal, healthy...

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

...worth of snowfall compacted into a very thin band, researchers were able to extract an isotope record that provided a picture of temperature and snowfall patterns near Siple Dome. The layers get thinner and thinner with depth, as more ice and snow piles up. But the thinness of the layers deposited near the end o...

UCLA scientists transform HIV into cancer-seeking missile

...e the melanoma had migrated," said Chen. When the researchers held the mouse under the camera, the luciferase illuminated the cancer cells, which glowed through the animal's bones, muscles and fur. The method is non-invasive and does not cause pain or harm to the animal. Though excited at proving that HIV can ...

New Breast Cancer Test Could Save Lives

A team of researchers at the University of Bristol is developing a revolutionary new test to detect breast cancer at an early stage. If successful, this test will be effective for women of all ages; given that breast cancer is the largest killer of women between the ages ...
