A new study has implicated the blocking of endocannabinoids -- signaling substances that are the brain's internal versions of the psychoactive chemicals in marijuana and hashish -- in the early pathology of Alzheimer's d...

The use of sentinel lymph node biopsy to stage early breast cancer increased in both black and white women from 2002 to 2007, but the rates remained lower in black than white patients, a disparity that contributed to dis...

A noninvasive way to detect heart-transplant rejection weeks or months earlier than previously possible has been devised by researchers. The test, which relies on the detection of increasing amounts of the donor's DNA in...

It's neuroscience's final frontier. Tiny bubbles will open the blood-brain barrier to sneak drugs into tumours – and we might treat Alzheimer's the same way

Not all sauropod dinosaurs were long-necked giants. Now, researchers have found miniature fossils that belonged to adult sauropods, revealing the processes that led to dwarf dinosaurs.

Bipolar children have greater activation in the right amygdala -- a brain region very important for emotional reaction -- than bipolar adults when viewing emotional faces. The study suggests that bipolar children might b...

This region, and for that matter much of our world's oceans, are often described as poorly explored. But what do we mean by poorly explored and why do we know so little?

Imaging and mapping of electric fields at radio frequencies (RF)* currently requires the use of metallic structures such as dipoles, probes and reference antennas. To make such measurements efficiently, the size of these...

Scientists have found spiders that hunt fish on every continent except Antarctica.

The first global survey of fish-eating spiders shows that they prey on fish on every continent except Antarctica, usually pouncing from the waterside

Good luck getting a cup of coffee, much less an espresso, aboard the International Space Station -- at least that's how it's been for ISS astronauts to date. But that could all change with Lavazza's plan to launch "ISSpr...
