UC Davis scientists show how cells control DNA synthesis in mitochondria

Aging, neurodegenerative disorders and metabolic disease are all linked to mitochondria, structures within our cells that generate chemical energy and maintain their own DNA. In a fundamental discovery with far-reaching implications, scientists at the University of California, Davis, now show how cells control DNA synthesis in mitochondria and couple it to mitochondrial division.

Researcher aims to make early detection of melanoma faster, cheaper without need for biopsy

Melanoma is a form of skin cancer that becomes dangerous when it spreads, but is treatable in its early stages. Doctors diagnose melanoma by cutting away a piece of a suspicious skin lesion -- a procedure known as a biopsy -- and testing it for malignant cells.

Researchers discover new biological pathway involved in Alzheimer's disease

Researchers have identified a new biological pathway involved in Alzheimer's disease. In experiments using fruit flies, blocking the pathway reduced the death of brain cells, suggesting that interfering with the pathway could represent a promising new strategy to treat the disease in human patients.

Researchers use FRET to make activation of AMPA receptors optically visible

Our brain is a high-performance computer. One of the key players in this complex system is the AMPA-type glutamate receptor. It ensures that neurotransmission proceeds at a breakneck pace from cell to cell.

Researchers find distinct, non-identical differences among retroviruses

In the most comprehensive study of its kind, researchers in the report that most types of retroviruses have distinct, non-identical virus structures.

MIT engineers develop new way to visualize RNA molecules in higher resolution

Cells contain thousands of messenger RNA molecules, which carry copies of DNA's genetic instructions to the rest of the cell. MIT engineers have now developed a way to visualize these molecules in higher resolution than previously possible in intact tissues, allowing researchers to precisely map the location of RNA throughout cells.

Researchers discover human factor that drives maturation of helper T cells

A powerful arm of the immune system is production of antibodies that circulate through the blood and neutralize invading pathogens. Although B cells actually manufacture antibody proteins, the process is aided by neighboring T cells, which shower B cells with cytokines to make them churn out high-quality antibody proteins--and remember how to do so.

Study provides insight into why individual mycobacteria respond differently to antibiotics

Tuberculosis is one of the most common infectious diseases in the world, infecting almost 10 million people each year. Treating the disease can be challenging and requires a combination of multiple antibiotics delivered over several months.

Scientists reveal how new adult-born neurons evolve in olfactory bulb of mice

Scientists from the Institut Pasteur and the CNRS were able to make real-time observations over a period of several months that reveal how new adult-born neurons are formed and evolve in the olfactory bulb of mice.

Study finds link between copper exposure and prion protein neurotoxicity

Iowa State University researchers have described with single-molecule precision how copper ions cause prion proteins to misfold and seed the misfolding and clumping of nearby prion proteins.

Laser-printed micropatterns can serve as platform for diagnostic applications

Laser printouts on paper might be used as a platform for low-cost organic electronics, microfluidic, or sensor applications. German scientists at Humboldt University Berlin have now developed a procedure for the selective coating of laser-printed micropatterns on paper.

New technique can help identify aggressive forms of DCIS

When a woman is diagnosed with the earliest stage of breast cancer, how aggressive should her treatment be? Will the non-invasive cancer become invasive? Or is it a slow-growing variety that will likely never be harmful?

Novel therapeutic approach may be effective for disrupting bacterial biofilms

Biofilms are communities of bacteria that adhere to a surface and are nearly impossible to eradicate when they are pathogenic, or disease-causing.

Scientists gain new insights into how cancer cells may squeeze through narrow blood vessels

The spread of cancer from a tumor's original location to other parts of the body can play a major role in whether the disease turns deadly. Many steps in this process, called metastasis, remain murky.

New research identifies flaws in LM-method for Lyme disease

A new microscopy technique (LM-method) developed to detect Lyme disease is unable to distinguish infected patients from healthy controls, yielding false-positive results that could lead doctors to over-diagnose a patient, according to new research published in the journal Infectious Diseases.

Therapeutic stem cells exit bloodstream in different way than previously thought

Researchers at North Carolina State University have discovered that therapeutic stem cells exit the bloodstream in a different manner than was previously thought. This process, dubbed angiopellosis by the researchers, has implications for improving our understanding of not only intravenous stem cell therapies, but also metastatic cancers.
