Magnetars – the dense remains of dead stars that erupt sporadically with bursts of high-energy radiation – are some of the most extreme objects known in the Universe. A major campaign using NASA's Chandra X-ray Observatory and several other satellites shows magnetars may be more diverse – and common – than previously thought.

As the human body fine-tunes its neurological wiring, nerve cells often must fix a faulty connection by amputating an axon — the "business end" of the neuron that sends electrical impulses to tissues or other neurons. It is a dance with death, however, because the molecular poison the neuron deploys to sever an axon could, if uncontained, kill the entire cell.

A known difficulty in fighting influenza (flu) is the ability of the flu viruses to mutate and thus evade various medications that were previously found to be effective. Researchers at the Hebrew University of Jerusalem have shown recently that another, more promising, approach is to focus on improving drugs that boost the body's natural flu killer system.

Scientists have uncovered a survival mechanism that occurs in breast cells that have just turned premalignant-cells on the cusp between normalcy and cancers-which may lead to new methods of stopping tumors.

Tomatoes, said to be the world's most popular fruit, can be made both better-tasting and longer-lasting thanks to UK research with purple GM varieties.

A brief visual task can predict IQ, according to a new study. This surprisingly simple exercise measures the brain's unconscious ability to filter out visual movement. The study shows that individuals whose brains are better at automatically suppressing background motion perform better on standard measures of intelligence.

Plants can't swat a bug or run away from one, but that doesn't mean that plants can't fight back. Plants have evolved unique and sophisticated immune systems to defend themselves against insects and pathogens. Plant hormones called jasmonates play an important role in this defense, but jasmonates have been found to also be important for plant growth. Now, researchers reporting in the May 23 issue

Gaucher disease causes debilitating and sometimes fatal neurodegeneration in early childhood. Recent studies have uncovered a link between the mutations responsible for Gaucher disease and an increased risk of developing Parkinson's disease later in life. New research published online on May 23 in the Cell Press journal Cell Metabolism indicates that the neurodegeneration found in Gaucher d

White tigers today are only seen in zoos, but they belong in nature, say researchers reporting new evidence about what makes those tigers white. Their spectacular white coats are produced by a single change in a known pigment gene, according to the study, appearing on May 23 in Current Biology, a Cell Press publication.

A billon-frames-per-second film has captured the vibrations of gold nanocrystals in stunning detail for the first time.

People eating at fast food restaurants largely underestimate the calorie content of meals, especially large ones, according to a paper published today on bmj.com.

As weather warms up off the coast of France, blooms of plankton have once again begun to form, creating a beautiful, multicolored swirl visible from space.NASA's Terra and Aqua satellites acquired these images of the colorful blooms on April 20 and May 4, according to the NASA Earth Observatory. On the later date, a noticeably larger bloom occurred, fueled by nutrient ru...
A largely forgettable rainfall provoked a growth in vegetation that, followed by a hot, near-record dry period, simply resulted in more fuel for potential wildfires.When it comes to Southern California's increasingly perilous fire season, you can blame both the lack of rain and the little rain we did have.
The appeal of owning your own property — and all the private goods that came with it — may have convinced nomadic humans to settle down and take up farming. So says a new study that tried to puzzle out why early farmers bothered with agriculture.
Douglas Trumbull's new project would use fast frame rates, huge screens, 4K digital for an "immersive" experience. Are audiences ready?
Chris Hadfield has conquered space. Now he's conquering the Internet, too.
Neuroscientist Henry Markram says he can build a supercomputer replica of the human brain. Now he has $1.3 billion to prove it.
Hospitals hoping to attract patients and build goodwill are teaming up with medical-screening companies to promote tests they say might prevent deadly strokes or heart disease. What their promotions don’t say is that an influential government panel recommends against many of the tests for people without symptoms or risk factors.
I detest household bugs. Abhor them. There isn’t a word strong enough to describe how I feel about bugs in my home. That hatred provokes guilt, because I fancy myself an environmentalist. As such, I’m supposed to feel a kinship with all creatures. We’re connected in a circle of life, a colorful tapestry, a delicate web of interdependence.
Bodily waste is widely considered a topic not to be discussed in polite company; it’s something to be flushed and forgotten. But a new book argues that waste, in all its human and animal forms, is worth getting to know intimately
Bacteria that live in the gut have been used to reverse obesity and Type-2 diabetes, animal studies show.
Vast reserves of shale oil is set to make the US an exporter rather than a leading importer, delivering a blow to Middle East oil producers that can expect to see demand fall, an International Energy Agency report observes.
The Sun has unleashed the most powerful eruption - a solar flare - of 2013 so far.
If Mercury was an orange, the juicy bit would all be dense metallic core, while planets further out would be peaches with pit-like cores – here's why
Big data might one day allow us to project how conflicts will develop, but choosing whether and how to intervene will always be difficult
