NASA looks at winds in developing tropical cyclone

On May 26 at 0100 UTC RapidScat saw strongest sustained surface winds northeast of the center in System 91L, the developing tropical cyclone, at a rate near 21 meters per second (46.9 mph/75.6 kph).The low pressure area located between Bermuda and the Bahamas, designated as System 91L became a little better defined today. NASA's RapidScat analyzed the system's winds, and NOAA's GOES-East satellite...

How a huge landslide shaped Zion National Park

This view of Zion Canyon in Utah's Zion National Park shows the flat valley floor created when part of the peak named the Sentinel collapsed in a gigantic landslide, creating a dam and forming a lake, which eventually filled in with sediment. A new University of Utah study provides the first direct date for the landslide, determining it happened 4,800 years ago and showing it was so large that it would have covered New York City's Central Park with 275 feet of debris. This photo is the cover image for the June issue of the Geological Society America's journal <i>GSA Today</i>, which is publishing the Utah study.A Utah mountainside collapsed 4,800 years ago in a gargantuan landslide known as a "rock avalanche," creating the flat floor of what is now Zion National Park by damming the...

Engineers discover a new gatekeeper for light

A photograph (left) shows the experimental set-up used to confirm the existence of the Bloch wave resonance, which was first predicted theoretically. An illustration (right) shows the interior of the experimental device, called a hollow periodic waveguide, which consists of two corrugated metallic plates separated by a variable distance of about one inch, and the upper plate can slide with respect to the lower. When researchers shot microwaves between the plates through the air, they were able to control which wavelengths of microwaves were allowed through by varying the position of the upper plate.Imagine a device that is selectively transparent to various wavelengths of light at one moment, and opaque to them the next, following a minute adjustment.

Predicting the spread of the Zika virus

The risk is given as the percentage of observing local transmission by the end of 2016, colored by intensity (0-15, 15-30, 30-45 and 45-60 percent, respectively). The origin country Brazil and countries that have already experienced case importation prior to importation event in Brazil are colored by grey.A new tool by Japan-based researchers predicts the risk of Zika virus importation and local transmission for 189 countries.

Scientists illuminate a hidden regulator in gene transcription

MIT scientists developed a super-resolution imaging technique, using a combination of multi-colored lasers and mirrors, to visualize very tiny, transient phenomena, such as enzyme clustering on genes.Gene transcription is the process by which DNA is copied and synthesized as messenger RNA (mRNA) -- which delivers its genetic blueprints to the cell's protein-making machinery.
