Solar activity not a key cause of climate change, study shows
Climate change has not been strongly influenced by variations in heat from the sun, a new scientific study shows.
Why is the sun going quiet?
The sun is our nearest star and the source of all our light and heat on Earth but recent reports have highlighted an ongoing steep decline in solar activity. ...
Calm solar cycle prompts questions about impact on Earth
The surface of the sun has been surprisingly calm of late—with fewer sunspots than anytime in in the last century—prompting curious scientists to wonder just what it might mean here on Earth.
Big step for next-generation fuel cells and electrolyzers
A big step in the development of next-generation fuel cells and water-alkali electrolyzers has been achieved with the discovery of a new class of bimetallic nanocatalysts that are an order of magnitude higher ...
Don't let denial get in the way of a good science story
There was a time when science was seen as a body secure knowledge, given credibility by the scientific method and peer review.
Acid raid, ozone depletion contributed to ancient extinction
Rain as acidic as undiluted lemon juice may have played a part in killing off plants and organisms around the world during the most severe mass extinction in Earth's history.
Clever technology decodes more information from single photons
It's not quite Star Trek communications—yet. But long-distance communications in space may be easier now that researchers at the National Institute of Standards and Technology (NIST) and Jet Propulsion ...
When a black hole shreds a star, a bright flare tells the story
(Phys.org) —Enrico Ramirez-Ruiz uses computer simulations to explore the universe's most violent events, so when the first detailed observations of a star being ripped apart by a black hole were reported ...
Image: Coronal loops in an active region of the sun
An active region of the sun just rotating into the view of NASA's Solar Dynamics Observatory gives a profile view of coronal loops over about a two-day period, from Feb. 8-10, 2014.
Controversial scientist claims pesticide toxicity 'proof'
A controversial French biologist, whose 2012 paper on the alleged dangers of pesticides was withdrawn, has published new claims that the chemicals were many times more toxic than advertised.
Explosive volcanoes light up Mercury's deep past
Mercury has long been a mystery to scientists. Until recently, knowledge of the planet was limited to the grey, patchy landscape revealed by the Mariner 10 probe, NASA's first mission to Mercury in the mid-1970s. ...
Clouds seen circling supermassive black holes (w/ video)
Astronomers see huge clouds of gas orbiting supermassive black holes at the centers of galaxies. Once thought to be a relatively uniform, fog-like ring, the accreting matter instead forms clumps dense enough ...
New look inside cell nucleus could improve cancer diagnostics
Researchers have successfully isolated and sequenced the entire messenger RNA – the "genetic photocopies" – contained in the nucleus of a single brain cell. This research, published in the journal Proceedings of ...
Source of Galapagos eruptions is not where models place it
Images gathered by University of Oregon scientists using seismic waves penetrating to a depth of 300 kilometers (almost 200 miles) report the discovery of an anomaly that likely is the volcanic mantle plume ...
