Researchers engineer bacteria that can detect tumor DNA

Pushing into a new chapter of technologically advanced biological sensors, scientists from the University of California San Diego and their colleagues in Australia have engineered bacteria that can detect the presence of ...

Frog eggs help researchers understand repair of DNA damages

The DNA replication process in which cells divide to create new cells also triggers repair of DNA damage, researchers from the University of Copenhagen report in a new study. The researchers studied extracts from frog eggs, ...

3-in-1 optical skin cancer probe

As thousands of vacationers hit the beach this summer, many of them will expose their unprotected bare limbs to direct UV sunlight, potentially putting them at risk of skin cancer later in life. To fight back, scientists ...

Tissue structure delays cancer development

Cancer growth normally follows a lengthy period of development. Over the course of time, genetic mutations often accumulate in cells, leading first to pre-cancerous conditions and ultimately to tumour growth. Using a mathematical ...

Nano-Bio-Chip Checks for Oral Cancer

(PhysOrg.com) -- The gentle touch of a brush on the tongue or cheek can help detect oral cancer with success rates comparable to more invasive techniques like biopsies, according to preliminary studies by researchers at Rice ...

Nanoparticles Detect and Purge Metastases in Lymph Nodes

Colonoscopy represents one of the great weapons against cancer. In one step, a physician can find precancerous lesions in the colon and then cut them out, an on-the-spot intervention that prevents cancer from developing. ...

Potential new tool for cervical cancer detection and diagnosis

Cervical cancer is, in many ways, a shining example of how successful the war on cancer can be. Thanks largely to the advent of Pap smear screening, U.S. cervical cancer deaths decreased dramatically, by more than 60 percent, ...

Virology: A marker for a cancer-causing virus

(Phys.org)—Depending on the strain, or genotype, of the human papillomavirus (HPV) (see image), the lesions it causes can range from relatively benign to cancer-causing. Differentiating between lesions caused by low-risk ...
