Whether for use in safe data encryption, ultrafast calculation of huge data volumes or so-called quantum simulation of highly complex systems: Optical quantum computers are a source of hope for tomorrow's computer techno...

Physicists at the Australian National University (ANU) have brought quantum computing a step closer to reality by stopping light in a new experiment.

When the sun, moon and Earth are aligned, high tidal stress may increase the chances that an earthquake will grow bigger than it otherwise might have been. --

Currently, excess body weight contributes to as many as 1 in 5 cancer-related deaths. Obesity is associated with increased risk of at least eight types of cancer. Now obesity has been identified as a health risk that is ...

Scientists have found antibiotic-resistant bacteria in prairie soils that had little or no exposure to human or animal activity.

Dramatic advances in laser technologies are enabling novel studies to explore laser-matter interactions at ultrahigh intensity. By focusing high-power laser pulses, electric fields (of orders of magnitude greater than fo...

A new WHO air quality model confirms that 92% of the world's population lives in places where air quality levels exceed WHO limits. Some 3 million deaths a year are linked to exposure to outdoor air pollution. Indoor air...

Dental surface restorations composed of dental amalgam, a mixture of mercury, silver, tin and other metals, significantly contribute to prolonged mercury levels in the body, according to new research.

Toxins from mold found growing on nuts or corn can weaken the airways' self-clearing mechanisms and immunity, opening the door for respiratory diseases and exacerbating existing ones, suggests a new study.

Biomedical engineers, artificial blood vessels bioengineered in the lab and implanted in young lambs are capable of growth within the recipient, a groundbreaking new study demonstrates. If confirmed in humans, these new ...

Patients in inpatient rehabilitation after a stroke, brain injury, or spinal cord injury have significant rates of interruptions of their rehab program--often including being transferred back to the hospital for treatmen...

Researchers have found that interval exercise training (resistance-based and cardiovascular) improves endothelial function in older adults. Resistance interval training in particular could help reduce the risk of heart d...

The association between provider case volume and outcomes has long been suggested in cancer care. A research team has completed a review of outcomes for patients with locally advanced squamous cell head and neck cancers ...

Non-alcoholic fatty liver disease (NAFLD), the most common liver disease worldwide, is increasing in prevalence and is currently estimated to affect approximately one-quarter of the general population. A new study reveal...

In the fall of 2010, I traveled to New Zealand, and one of the places I visited was the small south island city of Christchurch. I was charmed by the tree-lined Avon River, the English-style cathedral in the main square,...

Researchers have expanded the role of the newly discovered CRISPR protein C2c2 that targets RNA instead of DNA. C2c2 has been described as an RNA-guided RNA-cutting enzyme; however, a full understanding of how this prote...

I do not think it means what you think it means. Physics can often seem inconceivable. It's a field of strange concepts and special terms. Language often fails to capture what's really going on within the math and theori...

Bill Phillips explains how laser cooling, for which he shared the 1997 Nobel Prize in Physics, led to a revolution in timekeeping. This Nature Video was produced with support from Mars,... --

Shape-shifting materials that can be programmed to morph over time could lead to medical implants that unfold at controlled rates inside the body, a new study finds.

Sufferers of migraines, cluster headaches, tension headaches or other headache disorders are at greater risk of developing a thyroid condition called hypothyroidism, according to a new study.

New research offers unprecedented insights into the causes of childhood diarrhea, the second-leading cause of death of children worldwide, and suggests that the role of pathogens has been vastly underestimated.

A protein tracer shows a distinctive pattern of brain protein deposition specific to chronic traumatic encephalopathy, a disease typically confirmed after death. A link between brain injury and long-term health has been ...
