When temperature changes, many materials undergo a phase transition, such as liquid water to ice, or a metal to a superconductor. Sometimes, a so-called hysteresis loop accompanies such a phase change...
Reproduction is a complex process, requiring a huge variety of molecular and cellular interactions, many aspects of which remain a mystery to science.
The world inside the human cell grew a bit more interesting in recent years as the role of a new biological structure became clearer.It was long believed that most important operations in the cell occ...
A majestic ponderosa pine, standing tall in what is widely thought to have been the "center of the world" for the ancestral Puebloan people, may have more mundane origins than previously believed, acc...
Winter ice on the surface of Antarctica's Weddell Sea sometimes has an enormous hole called a polynya. A polynya that appeared in 2016 and 2017 offered a unique opportunity for oceanographers to monit...
The fame of the Majorana particle stems from its strange properties -- it is the only particle that is its own antiparticle -- and from its potential to be harnessed for future quantum computing.In re...
Rice University scientists have effectively quenched a debate over the mechanism behind a fluorescent biosensor that monitors neurons by sensing changes in voltage.The work led by Rice theoretical che...
A mysterious flash of X-rays has been discovered by NASA’s Chandra X-ray Observatory in the deepest X-ray image ever obtained. This source likely comes from some sort of destructive event, but it may ...
For decades, marine chemists have faced an elusive paradox. The surface waters of the world’s oceans are supersaturated with the greenhouse gas methane, yet most species of microbes that can generate ...
A star known by the unassuming name of KIC 8462852 in the constellation Cygnus has been raising eyebrows both in and outside of the scientific community for the past year. In 2015 a team of astronomer...
In ocean expanses where oxygen has vanished, newly discovered bacteria are diminishing additional life molecules. They help make virtual dead zones even deader.It’s natural for bacteria to deplete ni...
NGC 253 is the nearest spiral galaxy with a nuclear starburst. The nuclear region is so veiled by large amounts of dust associated to the star formation process that it has been unclear, until now, wh...
Using data on formal manufacturing plants in India, we report a large but imprecise speedup in productivity growth starting in the early 1990s (e.g., 1993–2007 compared to 1980–1992). We trace it to p...
Seagoing research figures prominently in the culture of ocean science, with new observations driving advances in understanding and pointing toward new questions. The challenge and excitement of explor...
The map, which can be viewed at http://is.gd/dibmap, was unveiled Jan. 8 at the 225th meeting of the American Astronomical Society in Seattle. The map will be discussed at a 2:15 p.m. PST press confer...
