Tiny self-assembling transport networks, powered by nano-scale motors and controlled by DNA created

Posted: 10 Nov 2013 03:44 PM PST

Tiny self-assembling transport networks, powered by nano-scale motors and controlled by DNA, have been developed by scientists.

Un-junking junk DNA

A new study shines new light on molecular tools our cells use to govern regulated gene expression.

Simple dot test may help gauge progression of dopamine loss in Parkinson's disease

Posted: 09 Nov 2013 04:28 PM PST

Could figuring out how much dopamine a patient with Parkinson's disease has lost be as simple as completing a dot test? Researchers hope the easy task might lead to ways of improving clinical treatment of Parkinson's patients.

Microbes swim to hydrogen gas

Researchers have discovered details on a speedy microorganism that needs hydrogen to produce methane.

Gene puts African Americans at higher risk for kidney failure, study says

Posted: 09 Nov 2013 12:37 PM PST

Genetic factors in African Americans with chronic kidney disease (CKD) put them at a greater risk for end-stage renal disease (ESRD) compared to white Americans, according to a new study released. Researchers contributed data from two separate studies: the African American Study of Kidney Disease and Hypertension (AASK) and the Chronic Renal Insufficiency Cohort Study (CRIC).

High clot risk for women admitted to hospital during pregnancy

Admission to hospital during pregnancy for reasons other than delivery carries a substantially increased risk of serious blood clots (known as venous thromboembolism or VTE), finds a study.

Lowering salt intake improves heart, kidney health of chronic kidney disease patients

Posted: 07 Nov 2013 04:18 PM PST

In patients with chronic kidney disease who lowered their salt intake for two weeks, excess extracellular fluid volume, blood pressure, and protein excretion in the urine all dropped considerably. If maintained long-term, the effects could reduce a patient's risk of progressing to kidney failure by 30%.

Improved decoding of DNA for custom medical treatments

Posted: 07 Nov 2013 01:20 PM PST

Scientists have moved a step closer to creating custom medical treatment plans based on a patient's DNA, pinpointing the root of a patient's illness and making sure treatment will not cause a fatal allergic reaction.

Cost-effective method accurately orders DNA sequencing along entire chromosomes

Posted: 07 Nov 2013 12:48 PM PST

A new computational method has been shown to quickly assign, order and orient DNA sequencing information along entire chromosomes. The method may help overcome a major obstacle that has delayed progress in designing rapid, low-cost -- but still accurate -- ways to assemble genomes from scratch. Data gleaned through this new method can also validate certain types of chromosomal abnormalities in cancer.

Female doctors twice as likely to screen low-risk women for cervical cancer

Posted: 07 Nov 2013 12:46 PM PST

For low-risk women, the likelihood that they get tested for HPV may depend on what clinic they visit, their doctor's status and whether their provider is male or female.
