A reconfigurable antenna array integrated with RF switches Posted: 10 Nov 2013 05:43 PM PST The recent rapid development of wireless communication systems has created a strong need for the development of new antenna structures. The research described in this project introduces the concept of reconfigurable antennas with switching beam control, operable at 5.8 GHz.

World's first commercial nanostructured bulk metal Posted: 10 Nov 2013 05:43 PM PST Scientists are introducing the world's first bulk nanostructured metal in commercial production.

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 Posted: 10 Nov 2013 03:43 PM PST 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.

Acid levels in diet could have profound effects on kidney health Posted: 09 Nov 2013 04:27 PM PST New research suggests that consuming extra fruits and vegetables, which are highly alkaline, improves kidney health. In patients with chronic kidney disease, those with high dietary acid levels experienced accelerated kidney function decline. In chronic kidney disease patients with low socioeconomic status, the detrimental effect of high dietary acid levels on progression to kidney failure was greater for blacks than for whites.

Preeclampsia during pregnancy may be linked with kidney failure risk Posted: 09 Nov 2013 04:27 PM PST New research suggests that preeclampsia during pregnancy is associated with an increased likelihood of developing kidney failure. However, after adjusting for diabetes and hypertension, the association was attenuated and no longer significant. Additional studies are needed to confirm the association of preeclampsia and kidney failure.

Microbes swim to hydrogen gas Posted: 09 Nov 2013 12:39 PM PST Researchers have discovered details on a speedy microorganism that needs hydrogen to produce methane.

Investigational drug effective in treating iron deficiency in kidney disease patients on dialysis Posted: 09 Nov 2013 12:38 PM PST Doctors will present late-breaking data showing that an investigational drug Triferic is well tolerated and effective in treating iron deficiency in patients with chronic kidney disease undergoing dialysis.

New therapeutic target identified for ALS Posted: 09 Nov 2013 12:38 PM PST A team of scientists has identified a novel therapeutic approach for the most frequent genetic cause of ALS, a disorder of the regions of the brain and spinal cord that control voluntary muscle movement, and frontal temporal degeneration, the second most frequent dementia.

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).

Use of calcium-channel blocker, antibiotic associated with small increased risk of kidney injury Posted: 09 Nov 2013 12:37 PM PST Among older adults taking a calcium-channel blocker, simultaneous use of the antibiotic clarithromycin, compared with azithromycin, was associated with a small but statistically significant greater 30-day risk of hospitalization with acute kidney injury, according to a study.

Peripheral prism glasses are cheap, effective vision rehab tool Posted: 08 Nov 2013 07:21 AM PST A multi-center study determined that real peripheral prism glasses are more helpful than sham peripheral prism glasses for patients with hemianopia during every day walking.

Study reveals TWEAK-Fn14 as key drug target Posted: 08 Nov 2013 06:13 AM PST A cellular pathway interaction known as TWEAK-Fn14, often associated with repair of acute injuries, also is a viable target for drug therapy that could prevent the spread of cancer, especially brain cancer, according to a study.

Allergic to insect stings: Allergy shots decrease anxiety, depression Posted: 08 Nov 2013 06:02 AM PST According to a study, allergy shots, also known as immunotherapy, can improve quality of life for insect sting allergy sufferers.

You can have a food allergy, and eat it too Posted: 08 Nov 2013 06:02 AM PST Have food allergies? If you answered yes, you know the best way to prevent a severe allergic reaction is to totally avoid the offending food. But according to new research, you may no longer have to avoid the food entirely.

The great disappearing act: Bone marrow receiver cured of allergy Posted: 08 Nov 2013 06:01 AM PST Not only can bone marrow transplants be life-saving for children with acute lymphocytic leukemia, they may also cure peanut allergies. According to research, a 10-year-old boy no longer had a peanut allergy after undergoing a bone marrow transplant.
