MicroCT-based virtual histology

Utah and Texas researchers combined miniature medical CT scans with high-tech computer methods to produce detailed three-dimensional images of mouse embryos - an efficient new method to test the safety of medicines and learn how mutant genes cause birth defects or cancer.

Researchers figure out how nuclear pores duplicate before cells divide

Researchers have long wondered how nuclear pores - the all-important channels that control the flow of information in and out of a cell's nucleus - double in number to prepare for the split to come when a cell divides. Now, for the first time, scientists at the Salk Institute for Biological Studies watched as new funnel-like pore structures formed from scratch, and inserted themselves into the nuclear membrane.

Magnetic nanotechnology holds promise in fighting cancer

Detecting cancer and reinventing computing are two challenges that seemingly have little, if anything, to do with each other. That is, unless you are a nanotechnologist like Shan Wang, an associate professor of materials science and engineering and of electrical engineering at Stanford.

Muscles burn lactic acid as well as carbos

In the lore of marathoners and extreme athletes, lactic acid is poison, a waste product that builds up in the muscles and leads to muscle fatigue, reduced performance and pain.

New design lets mini-microscope observe cells in vivo

Two eyes are better than one. Or more precisely, two lines of sight are better than one. That's the word from researchers at the Stanford School of Medicine, who have applied this adage to the design of a tiny microscope that is about the size of an M&M.

St. Jude develop strategy to speed future development of more effective and less toxic treatments for medulloblastoma

Investigators at St. Jude Children’s Research Hospital have developed a strategy to speed future development of more effective and less toxic treatments for medulloblastoma, a type of brain cancer. Medulloblastomas arise in the back of the brain and account for about 20 percent of childhood brain tumors.

Computer program lets people with Trigeminal neuralgia diagnose themselves

Trigeminal neuralgia, or TN, is a disorder affecting the areas of the face where the trigeminal nerve's branches are distributed, including the lips, eyes, nose, scalp, forehead, and upper and lower jaws.

Lubricin research points to future therapies for osteoarthritis

New evidence to explain how the body's natural joint lubricant prevents the wear and tear that can lead to osteoarthritis has been uncovered by researchers at Duke University's Pratt School of Engineering.The findings may lead to new methods for treating arthritis, the researchers said.

Proteins could help predict whether moles will progress into melanoma

For the first time, researchers studying patients with abnormal moles have identified proteins that could help predict whether such moles will progress into melanoma, the deadliest form of skin cancer.

Skin cancer facts

Up to two-thirds of all cancers may be prevented through dietary and lifestyle changes. In the case of skin cancer, this could not be more true.

Mayo Clinic discover cellular secret that may explain how certain cancers move and spread

If the mechanism that drives cancer movement - also called metastasis - can be understood well enough to manipulate it, new and better treatments can be developed for patients with metastatic cancers.

Studies show HPV testing is more sensitive than current screening methods

The current technique for screening for cervical cancer involves collecting cells by way of a pap smear and examining them under a microscope. Although this method has reduced cervical cancer in countries where it is regularly used, it has several weaknesses.

Phagocytosis depends more on particle shape than size

The research, which has far-reaching implications for immunology, vaccine development and drug delivery, is published today online in the Proceedings of the National Academy of Sciences by Samir Mitragotri, a UCSB professor of chemical engineering, and graduate student Julie A. Champion. The paper will be published in print on March 28.

New technology - desorption electrospray ionization detects the boundaries of cancerous tumors

Researchers at Purdue University have shown how a new ultra-fast chemical-analysis tool has numerous promising uses for detecting everything from cancer in the liver to explosives residues on luggage and "biomarkers" in urine that provide an early warning for diseases.
