Tropical Storm Iselle departs Hawaii while Julio stays well north

The Tropical Rainfall Measuring Mission or TRMM satellite passed over Tropical Storm Iselle and gathered data on clouds and rainfall as it affected Hawaii.

NASA sees the end of Tropical Depression Genevieve

Cloud tops were warming and precipitation was waning in Tropical Depression Genevieve when NASA's Aqua satellite flew overhead. Genevieve moved through all three Pacific Ocean regions (eastern, central and western) in its two week lifetime and met its end today.

Fires in Northern Washington State

The Pacific Northwest has been inundated with wildfires most stemming from lightning strikes during summer storms. Four of these wildfires can be seen in this natural-color Aqua satellite image collected by the Moderate Resolution Imaging Spectroradiometer, MODIS, instrument aboard. This image was taken on August 11, 2014. Actively burning areas, detected by MODIS's thermal bands, are outlined in red.

NASA sees a weaker Tropical Storm Julio far north of Hawaii

Tropical Storm Julio continues to weaken as it moves through cooler waters of the Central Pacific Ocean. NASA's Terra satellite passed over Julio and saw that the bulk of the clouds and precipitation were being pushed to the34 north of the center as the storm tracked far north of the Hawaiian Islands.

Could hemp nanosheets topple graphene for making the ideal supercapacitor?

SAN FRANCISCO, Aug. 12, 2014 — As hemp makes a comeback in the U.S. after a decades-long ban on its cultivation, scientists are reporting that fibers from the plant can pack as much energy and power as graphene, long-touted as the model material for supercapacitors. They're presenting theirresearch, which a Canadian start-up company is working on scaling up, at the 248th National Meeting & Exposition of the American Chemical Society (ACS), the world's largest scientific society.

Kessler Foundation scientists link environment & inclusion in adults with disabilities

West Orange, NJ. August 11, 2014. Kessler Foundation researchers have identified an association between the built environment and disability-related outcomes for adults with physical impairments. The article, Disability and the built environment: an investigation of community and neighborhood land uses and participation for physically impaired adults, was published in the July issue of Annals of Epidemiology (doi: 10.1016/j.annepidem.2014.05.003).

Follow the radio waves to exomoons, UT Arlington physicists say

Scientists hunting for life beyond Earth have discovered more than 1,800 planets outside our solar system, or exoplanets, in recent years, but so far, no one has been able to confirm an exomoon. Now, physicists from The University of Texas at Arlington believe following a trail of radio wave emissions may lead them to that discovery.

Genevieve downgraded to a tropical storm

Once Super Typhoon Genevieve has now been downgraded to a tropical storm. The storm is located approximately 819 nautical miles west-northwest of Midway Island. It is currently tracking northwestward at 8 knots per hour over the past six hours. Maximum significant wave height is 32 feet. Maximum sustained winds 70 knots gusting to 85 knots, with winds of 34 knots or higher occur within 80 to 105 miles of the cente,r and winds of 64 knots or higher occur within 15 miles of the center. No landmasses are currently threatened by this storm.

Julio embarking on weakening trend

The Central Pacific Hurricane Center has issued its 30th warning on Julio today at 1500 GMT. Julio's position at this point is 395 miles northeast of Honolulu, Hawaii moving northwest at 8 knots per hour. Julio is moving toward the northwest near 9 mph, 15 km/h. Maximum sustained winds are near 75 mph, 120 km/h, with higher gusts. Julio is expected to weaken slightly over the next 48 hours, down to tropical storm strength by tonight.

Southfork and Staley Complex fires in Oregon

The Southfork Complex fire began with a lightning strike on July 31, 2014. The complex of Murderers Creek South fire and the Buck Fork fire is located 20 miles southwest of John Day, Oregon and has affected 62,476 acres to date. The fire area experienced a shift in direction of the prevailing winds Sunday. There were short up-slope, up-canyon runs. At present there are 798 personnel fighting this fire complex.

All-you-can-eat at the end of the universe

At the ends of the Universe there are black holes with masses equaling billions of our sun. These giant bodies – quasars – feed on interstellar gas, swallowing large quantities of it non-stop. Thus they reveal their existence: The light that is emitted by the gas as it is sucked in and crushed by the black hole's gravity travels for eons across the Universe until it reaches our telescopes. Looking at the edges of the Universe is therefore looking into the past.

Destruction of 3 stars by black holes detected

Researchers from Moscow Institute of Physics and Technology and the Space Research Institute of the Russian Academy of Sciences have reported registering three possible occasions of the total destruction of stars by supermassive black holes at the centers of galaxies.Details are given in an article by IldarKhabibullin and Sergei Sazonov, accepted for publication by the Monthly Notices of the Royal Astronomical Society journal(a preprint is available at http://www.arXiv.org.

Spectacular 3-D sketching system revolutionizes design interaction and collaboration

Collaborative three-dimensional sketching is now possible thanks to a system known as Hyve-3D that University of Montreal researchers are presenting today at the SIGGRAPH 2014 conference in Vancouver. "Hyve-3D is a new interface for 3D content creation via embodied and collaborative 3D sketching," explained lead researcher Professor Tomás Dorta, of the university's School of Design. "The system is a full scale immersive 3D environment. Users create drawings on hand-held tables. They can then use the tablets to manipulate the sketches to create a 3D design within the space".

The Lancet Neurology: Study highlights pervasive problem of sleep deprivation in astronauts

Astronauts suffer considerable sleep deficiency in the weeks leading up to and during spaceflight, according to the most extensive study of sleep during spaceflight ever conducted, published in The Lancet Neurology journal.

Fatigue and sleep deficiency are common complaints among astronauts, but this is the most comprehensive study to include both objective evaluation of sleep (via an actigraph, a device worn on the wrist which records sleep and wake cycles) and subjective evaluations (via a daily diary recording alertness and sleep quality).
