NASA's Aqua satellite captured an image of Cyclone Zane headed toward the northern Cape York Peninsula of Queensland where it is expected to make landfall by May 2 and cross into the Gulf of Carpentaria.
A cyclone Warning is in effect for coastal areas from Mapoon to Cape York to Cape Flattery.
According to the Cape Cod Times of April 30, 2013: "The Massachusetts Army National Guard's Natural Resource Program is conducting a prescribed burn at the Upper Cape base. The burn will be held in partnership with federal, state and non-profit agencies. The objective of the burn is to reduce the risk of wildfire by eliminating the heavy buildup of dead wood and debris that can act as fuel. Prescribed burns also manage the habitat for endangered and rare species on the 22,000 acre base. Local fire departments receive training during the prescribed burns.
Our global networks have generated many benefits and new opportunities. However, they have also established highways for failure propagation, which can ultimately result in man-made disasters. For example, today's quick spreading of emerging epidemics is largely a result of global air traffic, with serious impacts on global health, social welfare, and economic systems.
Using the same devious mechanism that enables some bacteria to shrug off powerful antibiotics, scientists have developed solar-powered nanofilters that remove antibiotics from the water in lakes and rivers twice as efficiently as the best existing technology. Their report appears in ACS' journal Nano Letters.
NASA scientists don't often learn that their spacecraft is at risk of crashing into another satellite. But when Julie McEnery, the project scientist for NASA's Fermi Gamma-ray Space Telescope, checked her email on March 29, 2012, she found herself facing this precise situation.
While Fermi is in fine shape today, continuing its mission to map the highest-energy light in the universe, the story of how it sidestepped a potential disaster offers a glimpse at an underappreciated aspect of managing a space mission: orbital traffic control.
In Western Australia, the wet season occurs between December and March and the dry season between May and October. The reversals of prevailing winds in the two season drives the shift from wet to dry and back.
In April and May, fires usually burn themselves out within a few days due to the fact that even though there are dry spots that may catch fire, the wet area around them will keep the fires from burning out of control. The worst time for fire is late in the dry season, when vegetation has dried to tinder and blazes tend to be uncontrollable, intense, and dangerous.
Infrared data indicates temperatures of cloud tops and the surface of the sea beneath tropical cyclones, and NASA's AIRS instrument captured an infrared look at low pressure area System 92P in the Southwestern Pacific Ocean that hinted it was rapidly developing into Tropical Cyclone Zane. Zane is expected to make landfall in northeastern Queensland on May 1 at cyclone strength.
Even as the snow begins to retreat in the eastern part of Russia, fires are being set to clear the land for planting. This Moderate Resolution Imaging Spectroradiometer (MODIS) image from the Aqua satellite was captured on April 29, 2013. MODIS shows the fires as red dots on this image and also visible are smoke plumes rising from the fires which are most likely the result of growing-season activities for farmer in the region.
HOUSTON – (April 30, 2013) – Women engineers are underpaid for their contributions to technical activities, due to cultural ideologies in the engineering profession, according to Rice University research.
"Cultural ideologies within professions may seem benign and have little salience outside of a profession's boundaries, but may play an important role in wage inequality," said Rice Assistant Professor of Sociology Erin Cech.
Staring at a small patch of sky for more than 50 hours with the ultra-sensitive Karl G. Jansky Very Large Array (VLA), astronomers have for the first time identified discrete sources that account for nearly all the radio waves coming from distant galaxies. They found that about 63 percent of the background radio emission comes from galaxies with gorging black holes at their cores and the remaining 37 percent comes from galaxies that are rapidly forming stars.
Water ice exists in large quantities in many small craters near the Moon's north pole, according to a new study.
Spudis et al. present initial results from the miniature synthetic aperture radar (Mini-SAR) experiment on board the Indian Chandrayaan 1 spacecraft, which mapped most of the area near the north pole of the Moon between February and April 2009. The Mini-SAR instrument collected data on the polarization of radio waves reflected off the lunar surface.
Present-day gully activity on Mars provides new evidence for transient liquid water. Reiss et al. study images of the Russell crater dune field on Mars taken by the High Resolution Imaging Science Experiment from November 2006 to May 2009.
As planets age they become darker and cooler. Saturn however is much brighter than expected for a planet of its age - a question that has puzzled scientists since the late sixties. New research published in the journal Nature Geoscience has revealed how Saturn keeps itself looking young and hot.
Researchers from the University of Exeter and the Ecole Normale Supérieure de Lyon found that layers of gas, generated by physical instability deep within the giant planet, prevent heat from escaping and have resulted in Saturn failing to cool down at the expected rate.
PITTSBURGH—Online crowds can be an important tool for teaching the ins and outs of innovation, educators at Carnegie Mellon University and Northwestern University say, even when the quality of the feedback provided by online sources doesn't always match the quantity.
2013 — A research report released today from The Children's Hospital of Philadelphia (CHOP) provides specific recommendations for optimizing the rear seat of passenger vehicles to better protect its most common occupants — children and adolescents. By bringing technologies already protecting front seat passengers to the rear seat and modifying the geometry of the rear seat to better fit this age group, the US could achieve important reductions in serious injury and death.
