There are electrical signals in the nervous system, the brain and throughout the human body and there are tiny magnetic fields associated with these signals that could be important for medical science. Researchers have just developed a method that could be used to obtain extremely precise measurements of ultra-small magnetic fields.
Direct evidence for a positive feedback in climate change: Global warming itself will likely accelerate warming
A new study has confirmed the existence of a positive feedback operating in climate change whereby warming itself may amplify a rise in greenhouse gases resulting in additional warming.
Scientists have long puzzled over the planet Mercury's excessively dark surface. New research suggests that carbon from passing comets could be the planet's mystery darkening agent.
New technology could result in optical switches with sub-square-micron footprints, potentially allowing densely packed switching fabrics on a chip.
Analysis of 20 years of satellite data has revealed the total amount of vegetation globally has increased by almost 4 billion tons of carbon since 2003. This is despite ongoing large-scale deforestation in the tropics.

Odds of reversing ICU patients' prior preferences to forgo life-sustaining therapies vary widely across the U.S.
Intensive care units across the United States vary widely in how they manage the care of patients who have set preexisting limits on life-sustaining therapies, such as authorizing do-not-resuscitate (DNR) orders and prohibiting interventions such as feeding tubes or dialysis, according to new research.
Antibodies from dromedary camels protected uninfected mice from Middle East Respiratory Syndrome (MERS), and helped infected mice expunge the disease, according to a study.
Warming winters have allowed mountain pine beetle outbreaks in the coldest areas of the western United States, but milder winters can't be blamed for the full extent of recent outbreaks in the region, a study finds.
An outbreak of a novel Escherichia coli (E.coli) strain resistant to antibiotics has been linked to contaminated endoscopes in a Washington state hospital. The study indicates that industry standard cleaning guidelines, which were exceeded by hospital staff, may not be sufficient for sterilizing endoscopes adequately.
A short burst of intensive exercise before eating a high fat meal is better for blood vessel function in young people than the currently recommended moderate-intensity exercise, according to a new study. Cardiovascular diseases including heart attacks and stroke a leading cause of death, and the process underlying these diseases start in youth. An impairment in the function of blood vessels is thought to be the earliest event in this process, and this is known to occur in the hours after consuming a high fat meal.
Prototype 'nanoneedles' generate new blood vessels in mice, paving way for new regenerative medicine
Scientists have developed tiny 'nanoneedles' that have successfully prompted parts of the body to generate new blood vessels, in a trial in mice. The researchers hope their nanoneedle technique could ultimately help damaged organs and nerves to repair themselves and help transplanted organs to thrive.
Researchers have discovered that potentially aggressive T-cells that might lead to auto-immune disease can instead be enlisted to help "police" over-active immune responses, via the molecule CD5. This new breakthrough may open the door to design better treatments for autoimmune diseases, they say.
Biomedical researchers have successfully converted microbubble technology already used in diagnostic imaging into nanoparticles that stay trapped in tumors to potentially deliver targeted, therapeutic payloads.
Using a new high-speed, high-resolution imaging method, researchers were able to see blood flow and other functions inside a living mouse brain at faster rates than ever before.
New insight into the link between neurodegenerative disorders and inflammation has been gained by a new study that provides a framework to explore more fully the possibility that viral infection may lead to onset of these diseases.
Researchers have captured images of the underlying biological activity within brain cells and their tree-like extensions, or dendrites, in mice that show how their brains sort, store and make sense out of information during learning.
A new drug that shows potential in laboratory studies against a rare type of acute leukemia has been developed by scientists. And additional studies suggest the same compound could play a role in prostate cancer treatment as well, they say.
Characterizing associations between socioeconomic factors and children's brain development, a team of investigators reports correlative links between family income and brain structure. Relationships between the brain and family income were strongest in the lowest end of the economic range -- suggesting that interventional policies aimed at these children may have the largest societal impact.
A study of peanut consumption showed that including them as a part of a high fat meal improved the post-meal triglyceride response and preserved endothelial function. Vascular dysfunction plays a major role in the development of atherosclerosis and the formation of coronary plaques and lesions that lead to coronary artery disease.
