Tropical Storm Simon is following the path of several other tropical storms that formed in the Eastern Pacific Ocean by crawling northward along the western coastline of Mexico. NOAA's GOES-West satellite captured an infrared image of Simon on Oct. 3 that showed the eastern side of the storm over Mexico.

NHC has not posted watches or warnings on Simon, but the tropical storm is large and close enough to shore to generate some heavy rainfall totals and rough surf.
Simon is expected to produce rainfall amounts of 3 to 5 inches with isolated amounts around 8 inches through Friday, Oct. 3 across Western Guerrero and Michoacan, Colima, western Jalisco and Nayarit in western Mexico. These rains could cause flash flooding and mud slides.
About one-fifth of the Earth's atmosphere is oxygen, pumped out by green plants as a result of photosynthesis and used by most living things on the planet to keep our metabolisms running. But before the first photosynthesizing organisms appeared about 2.4 billion years ago, the atmosphere likely contained mostly carbon dioxide, as is the case today on Mars and Venus.
The team (a collaboration between SISSA, the International Centre for Theoretical Physics "Abdus Salam" ICTP of Trieste, the Italian National Research Council CNR, and the Swiss Federal Laboratories for Materials Science and Technology) conducted a theoretical, simulation-based study.
PULLMAN, Wash.—A Washington State University undergraduate has helped develop a new method for detecting water on Mars. Her findings appear in Nature Communications, one of the most influential general science journals.
Kellie Wall, 21, of Port Orchard, Wash., looked for evidence that water influenced crystal formation in basalt, the dark volcanic rock that covers most of eastern Washington and Oregon. She then compared this with volcanic rock observations made by the rover Curiosity on Mars' Gale Crater.
Scientists have created a new map of the world's seafloor, offering a more vivid picture of the structures that make up the deepest, least-explored parts of the ocean.
The feat was accomplished by accessing two untapped streams of satellite data.
Thousands of previously uncharted mountains rising from the seafloor, called seamounts, have emerged through the map, along with new clues about the formation of the continents.
Despite the scientific interest, there was little progress in finding the particle until 2001 when the physicist Alexei Kitaev (now a professor at the University of California-Santa Barbara) predicted that, under the correct conditions, a Majorana fermion would appear at each end of a superconducting wire. Superconductivity is the phenomenon when a material can carry electricity without any resistance. In Kitaev's prediction, inducing some types of superconductivity would cause the formation of Majoranas.
Accessing two previously untapped streams of satellite data, scientists at Scripps Institution of Oceanography at UC San Diego and their colleagues have created a new map of the world's seafloor, creating a much more vivid picture of the structures that make up the deepest, least-explored parts of the ocean. Thousands of previously uncharted mountains rising from the seafloor and new clues about the formation of the continents have emerged through the new map, which is twice as accurate as the previous version produced nearly 20 years ago.
Where are the quantum computers? Aren't they supposed to be speeding up decryption and internet searches? After two decades of research, you still can't find them in stores. Well, it took two decades or more of research dedicated to semiconductors and circuit integration before we had digital computers. For quantum computers too it will take technology more time to catch up to the science
When asked to describe a forest or a meadow, most people would probably begin with the plants, the species diversity, or the color of the foliage. They probably wouldn't pay much attention to the animals living in the soil.
But a new Yale-led study shows the critical importance of earthworms, beetles, and other tiny creatures to the structure of grasslands and the valuable ecosystem services they provide.
A group of researchers from Switzerland has thrown light on the precise mechanisms responsible for the impressive ability of nanoparticles to detect fingermarks left at crime scenes.
Publishing their results today, 2 October, in IOP Publishing's journal Nanotechnology, the researchers have provided evidence contesting the commonly accepted theory that nanoparticles are attracted to fingermarks electrostatically.
AUSTIN, Texas—A team led by scientists at the University of Texas at Austin's Institute for Geophysics has for the first time directly observed multiple parts of Greenland's subglacial plumbing system and how that system evolves each summer to slow down the ice sheet's movement toward the sea.
These new observations could be important in accurately modeling Greenland's future response to climate change.
Pity the poor lithium ion. Drawn relentlessly by its electrical charge, it surges from anode to cathode and back again, shouldering its way through an elaborate molecular obstacle course. This journey is essential to powering everything from cell phones to cordless power tools. Yet, no one really understands what goes on at the atomic scale as lithium ion batteries are used and recharged, over and over again.
An international group of researchers led by Dr. Warren E. Piers (University of Calgary) and Dr. Heikki M. Tuononen (University of Jyväskylä) has been able to isolate and characterize an important chemical intermediate whose existence has, so far, only been inferred from indirect experimental evidence.
One of the most iconic forms of avant-garde cuisine, also known as molecular gastronomy, involves the presentation of flavorful, edible liquids — like cocktails or olive oil — packaged into spheres. Now a team of scientists, in collaboration with world-renowned chef Ferran Adriá, is getting to the bottom of what makes these delectable morsels possible. Their findings appear in ACS' The Journal of Physical Chemistry B.
