A specific kind of natural nanoparticles, called low-density lipoproteins (LDL), are fascinating scientists because their modification plays a key role in people affected by high cholesterol and atherosclerosis. LDL from healthy people behaved differently when subjected to high pressure compared to LDL affected by the common diseases studied, according to new research.

Sequencing the DNA of the MRSA superbug can accurately identify patients most at risk of death and could help medics develop new treatments as we move towards personalised medicine, say scientists.

Decreased brain pH in the patients with schizophrenia and bipolar disorder has been considered to be the result of secondary factors associated with the diseases, such as medication and agonal state. However, the researchers of the present study suggest that decreased brain pH is a primary feature of the diseases themselves, based on the current findings from systematic investigation using five animal models, which are devoid of such secondary factors.

Future space exploration aims to fly further from Earth than ever before. New research examines the robotic phase of the Asteroid Redirect Mission (ARM). In addition to taking manned spaceflights deeper into space than ever before, the proposed mission would also bring some benefit for planetary science.

Insurance companies end up covering proton therapy treatment for pediatric cancer patients in 97 percent of the cases they originally deny once those decisions are appealed. Researchers analyzed five years of coverage decisions at Penn's Roberts Proton Therapy Center. They discovered that roughly one in 10 pediatric cancer patients are initially denied coverage for the cutting edge and costly treatment - yet nearly all patients ultimately get approval.

A new study delves into the mystifying fact that wounds in your mouth heal faster and more efficiently than wounds elsewhere.

Gestational exposure to airborne particles derived from diesel exhaust can modify DNA in utero and alter the expression of genes that potentially increase susceptibility to adult heart failure, suggests a study in mice.

A new study finds that a specific drug regimen administered prior to and after surgery significantly reduces the risk of post-surgical cancer recurrence.

Current strategies for correcting misinformation about the dangers of vaccinations have the opposite effect and reinforce ill-founded beliefs, a study suggests.

For the first time, physicists used extreme ultraviolet radiation (XUV) for this process, which was generated in their own laboratory, and they were thus able to perform the first XUV coherence tomography at laboratory scale. This radiation has a wavelength of between 20 and 40 nanometers - from which it is therefore just a small step to the X-ray range.

A scheme launched by the Department of Health in 2011 to help patients stick to their drug regimens has been so successful, that in its first five years, it will save NHS England £517.6m in the long-term, a team of health economists has found.

Learning involves constant restructuring of nerve-cell connections. This requires specialized transport systems to ensure that these specific synapses can structurally and functionally be modified. One such delivery mechanism has now been characterized.

A healthy global debate has occurred concerning the benefits of using non-native trees for restoring some aspects of ecosystem function in degraded habitats. In many cases, the stresses associated with establishing seedlings disallow most native tree species from becoming successfully established in harsh planting sites. The tolerant non-native trees enable successes that would otherwise be unachievable.

Scientists and engineers have invented a range of bioactive 'tissue papers' made of materials derived from organs that are thin and flexible enough to even fold into an origami bird. The new biomaterials can potentially be used to support natural hormone production in young cancer patients and aid wound healing.

Researchers have discovered that defects in the transport of lysosomes within neurons promote the buildup of protein aggregates in the brains of mice with Alzheimer's disease. The study suggests that developing ways to restore lysosome transport could represent a new therapeutic approach to treating the neurodegenerative disorder.
