Our Galaxy's "geysers" are towers of power

The outflows were were detected by astronomers from Australia, the USA, Italy and The Netherlands. They report their finding in today's issue of Nature.

"These outflows contain an extraordinary amount of energy — about a million times the energy of an exploding star," said the research team's leader, CSIRO's Dr Ettore Carretti.

"These outflows contain an extraordinary amount of energy — about a million times the energy of an exploding star,"

But the outflows pose no danger to Earth or the Solar System.

Study of Southern Ocean critical to understanding of climate change

Whether it's the economics of clean energy, the politics of Washington or claims over the severity of the problem itself, the debate over climate change is loud and crowded. One aspect that often goes overlooked is the Southern Ocean ringing Antarctica at the bottom of the globe. But that, says Jorge Sarmiento, is about to change.

Communication is Key to Medication Adherence

Even the best medicines in the world can be rendered ineffective if they are not taken as prescribed. The problem known as medication “non-adherence” is a major health issue in the United States, contributing to worse outcomes for people who have diabetes and other chronic diseases.

Common data determinants of recurrent cancer are broken, mislead researchers

In order to study the effectiveness or cost effectiveness of treatments for recurrent cancer, you first have to discover the patients in medical databases who have recurrent cancer. Generally studies do this with billing or treatment codes – certain codes should identify who does and does not have recurrent cancer. A recent study published in the journal Medical Care shows that the commonly used data determinants of recurrent cancer may be misidentifying patients and potentially leading researchers astray.

Promising compound restores memory loss and reverses symptoms of Alzheimer's

New research in the FASEB Journal by NIH scientists suggests that a small molecule called TFP5 rescues plaques and tangles by blocking an overactive brain signal, thereby restoring memory in mice with Alzheimer's.

Cave dwelling nettle discovered in China

South West China, Myanmar and Northern Vietnam contain one of the oldest exposed outcrops of limestone in the world. Within this area are thousands of caves and gorges. It is only recently that botanists have sought to explore the caves for plants. This exploration is yielding many new species new to science, that are known only from these habitats. The current study was published in the open access journal PhytoKeys.
