Scaling up tissue engineering
Science Daily - 8 Mar 2016 00:27
A method has been created for 3-D bioprinting thick vascularized tissue constructs composed of human stem cells, extracellular matrix, and circulatory channels lined with endothelial blood vessel cells. The resulting net...
Death by gamma-ray bursts may place first lower bound on the cosmological constant
Phys.org - 7 Mar 2016 18:30
(Phys.org)--Sometimes when a star collapses into a supernova, it releases an intense, narrow beam of gamma rays. Gamma-ray bursts often last just a few seconds, but during that time they can release as much energy as the...
Hundred million degree fluid key to fusion
Phys.org - 7 Mar 2016 18:04
Scientists developing fusion energy experiments have solved a puzzle of why their million-degree heating beams sometimes fail, and instead destabilise the fusion experiments before energy is generated.
Plasma processing technique takes SNS accelerator to new energy highs
Phys.org - 7 Mar 2016 16:20
A novel technique known as in-situ plasma processing is helping scientists get more neutrons and better data for their experiments at the Spallation Neutron Source at the Department of Energy's Oak Ridge National Laborat...
Iowa State engineers develop flexible skin that traps radar waves, cloaks objects
EurekAlert! - 7 Mar 2016 09:00
(Iowa State University) Iowa State engineers have developed a 'meta-skin' that uses liquid-metal technology to trap radar waves and cloak objects from detection. By stretching the flexible meta-skin, the device can be tu...
New placenta model could reveal how birth defect-causing infectious agents cross from mother to baby
Science Daily - 8 Mar 2016 00:33
Researchers have devised a cell-based model of the human placenta that could help explain how pathogens that cause birth defects, such as Zika virus, cross from mother to unborn child.
Eye cells may use math to detect motion
Science Daily - 8 Mar 2016 00:28
In a study of mice, scientists showed how one type of neuron in the eye may distinguish moving objects. The study suggests that the NMDA receptor, a protein normally associated with learning and memory, may help neurons ...
Towards the goal of precision therapy in hepatocellular carcinoma
Science Daily - 8 Mar 2016 00:28
Hepatocellular carcinoma is a highly lethal disease, therefore effective and tolerable treatment is urgently needed. Authors of a new report provide an updated review of the genetic abnormalities and mechanisms that driv...
Dementia plaques attack language center of brain
Science Daily - 8 Mar 2016 00:28
The recent ability to peer into the brain of living individuals with a rare type of language dementia, primary progressive aphasia, provides important insight into the beginning stages of this disease, when it is caused ...
Discovery identifies new treatment target for age-releated macular degeneration, Alzheimer's
Science Daily - 8 Mar 2016 00:27
For the first time, researchers have shown that a protein critical to the body's ability to remove waste products from the brain and retina is diminished in age-related macular degeneration, after first making the discov...
Drug-loaded nanocarriers in tumor targeted drug delivery
Science Daily - 8 Mar 2016 00:27
Nanoparticulate delivery systems in cancer therapies provide better penetration of therapeutic and diagnostic substances with the cancerous tissue in comparison to conventional cancer therapies, report scientists.
Huntington's disease gene dispensable in adult mice
Science Daily - 8 Mar 2016 00:27
Adult mice don't need the gene that, when mutated in humans, causes the inherited neurodegenerative disorder Huntington's disease. The finding suggests that treatment strategies for Huntington's that aim to shut off the ...
Songbirds pinpoint effects of Huntington's disease
Science Daily - 8 Mar 2016 00:27
Scientists have parsed the role of the Huntington's disease gene in an area of the songbird's brain responsible for complex, sequential movements. These findings not only give a clearer view of how the genetic mutation t...
Cancer cells eat their neighbors' 'words'
Science Daily - 8 Mar 2016 00:02
Cancer cells are well-known as voracious energy consumers, but even a veteran cancer-metabolism researcher was surprised by their latest exploit: Experiments in his lab show that some cancer cells get 30-60 percent of th...
Healthy lifestyle advice provides long-term benefits
Science Daily - 7 Mar 2016 23:45
In a recently published study, providing advice over a 5-year period about leading a healthy lifestyle reduced the risk of heart-related deaths over the next 40 years.
How cancer cells fuel their growth
Science Daily - 7 Mar 2016 23:45
Amino acids, not sugar, supply most building blocks for tumor cells, scientists have been surprised to find. These findings offer a new way to look at cancer cell metabolism, a field of research that scientists hope will...
Genes influence sleep/wake timing of seizures in people with epilepsy
Science Daily - 7 Mar 2016 23:44
New research shows that genetics plays a role in sleep/wake timing of seizures. Researchers studied 1,395 individuals with epilepsy in families containing multiple people with epilepsy to determine whether sleep/wake tim...
Mutated gene safeguards against heart attacks
Science Daily - 7 Mar 2016 23:40
People with a specific gene mutation have a 50 percent lower risk of suffering a heart attack. This is what an international team of researchers discovered in a broad comparative study. If this gene were switched off wit...
