NOAA Solution to Lionfish Invasion, eat them!
August 8, 2010 10:28 AM - Roger Greenway, ENN
A new NOAA study looking at how to curb the rapid growth of lionfish, an invasive species not native to the Atlantic Ocean, suggests that approximately 27 percent of mature lionfish will have to be removed monthly for one year to reduce its population growth rate to zero. But the good news is that the invasive fish happens to be delicious—and NOAA is encouraging chefs to find new ways to introduce it to U.S. consumers. Lionfish are native to the western and central Pacific Ocean, but have established themselves from North Carolina to South America. They are a popular aquarium fish that were likely first released in Florida waters in the mid-1980s. Since then, the species has spread rapidly. Scientists and public officials are seriously concerned at the effect lionfish are having on reef ecosystems, since this predator is capable of rapid population growth and outcompeting native fish for food and territory.
Prayer and Health
August 6, 2010 12:25 PM - Andy Soos, ENN
There has always been a desire in the spirits of human beings to hope and sometimes believe in the effects of prayer in healing. Belief and the subsequent proof has always been hard to find or to do. Findings from a new international study of healing prayer suggest that prayer for another person's healing just might help -- especially if the one praying is physically near the person being prayed for. Candy Gunther Brown, an associate professor in the Department of Religious Studies at Indiana University Bloomington, led the study of proximal intercessory prayer for healing.
New Findings on the H1N1 Virus
August 6, 2010 09:56 AM - David A Gabel, ENN
Does anybody still remember swine flu? It caused a big uproar last winter and sent millions of people to their doctors to request the Tamiflu vaccine. New findings on the virus have been uncovered by researchers at the University of Wisconsin-Madison. They found that the H1N1 virus used a new biochemical trick to spread rapidly among humans and cause an epidemic. The structure of the virus evolved to allow it to interact with the cellular structure of mammals.
The Views of Mars
August 5, 2010 04:40 PM - Andy Soos, ENN
Of all the planets in our solar system Mars has always been the one most dreamers think of. Many science fiction myths have been based on Mars such as Edgar Rice Burroughs Barsoom and its many canals as well as the Ray Bradbury Martian Chronicles. All dreamed of a friendlier Mars than has been found. Now all can see detailed images of Mars. The latest set of new images from the telescopic High Resolution Imaging Science Experiment Camera on NASA's Mars Reconnaissance Orbiter offers detailed views of diverse Martian landscapes.
BP gusher stopped, most remaining oil degrading naturally
August 5, 2010 07:10 AM - Roger Greenway, ENN
The National Oceanic and Atmospheric Administration (NOAA) has released a major report by the federal government addresses the fate of the oil released while the well was gushing, and what is likely to happen to the remaining oil in the ocean. The report was prepared by a team of federal agencies and scientists from NOAA, USGS, and NIST, and as well as independent scientists from universities, Environment Canada, Exxon Mobil, and other companies. The study concludes that the vast majority of the oil from the BP oil spill has either evaporated or been burned, skimmed, recovered from the wellhead or dispersed much of which is in the process of being degraded. A significant amount of this is the direct result of the robust federal response efforts. A third (33 percent) of the total amount of oil released in the Deepwater Horizon/BP spill was captured or mitigated by the Unified Command recovery operations, including burning, skimming, chemical dispersion and direct recovery from the wellhead, according to a federal science report released today. An additional 25 percent of the total oil naturally evaporated or dissolved, and 16 percent was dispersed naturally into microscopic droplets. The residual amount, just over one quarter (26 percent), is either on or just below the surface as residue and weathered tarballs, has washed ashore or been collected from the shore, or is buried in sand and sediments. Dispersed and residual oil remain in the system until they degrade through a number of natural processes.
Climate Models and Warming
August 4, 2010 03:16 PM - Andy Soos, ENN
Climate models use various methods to simulate the interactions of the atmosphere, oceans, land surface, and ice. All climate models take account of incoming energy as short wave electromagnetic radiation, chiefly visible and short wave infrared, as well as outgoing energy as long wave infrared electromagnetic radiation from the earth. Any imbalance results in a change in temperature. The most talked about models of recent years have been those relating temperature to emissions of carbon dioxide. These models project an upward trend in the surface temperature record, as well as a more rapid increase in temperature at higher altitudes. Researchers at the Max Planck Institute for Meteorology in Hamburg have developed a new model that specifies the maximum volumes of carbon dioxide that humans may emit to remain below the increased climate warming of two degrees Celsius. To do this, the scientists incorporated into their calculations data relating to the carbon cycle, namely the volume of carbon dioxide absorbed and released by the oceans and forests.
iPads for New Med Students at UC Irvine
August 4, 2010 10:23 AM - David A Gabel, ENN
Goodbye heavy textbooks. Goodbye notebooks filled with doodles and illegible handwriting. The iPad has now arrived to the world of academia. The University of California Irvine (UCI) School of Medicine’s incoming class of 2014 will all be receiving iPad tablet computers fully loaded with everything they need for their first year of courses. The wireless, hand-held computers will contain hundreds of medical applications and learning tools that can be adapted to each student's unique learning style.

Solar power is the generation of electricity from sunlight. This can be direct as with photovoltaics, or indirect as with concentrating the sun's rays to boil water which is then used to provide power. Solar energy can be obtained in a variety of different ways. Passive solar occurs when you build your house in a manner that takes advantage of the low angle winter sun and/or when the mass of your house is used to absorb the sun’s heat in winter. In addition, passive solar also refers to keeping your house cooler in the winter months by making adjustments that include placing trees and awnings along the south side of a house.
International Ice Core Team Hits Bedrock in Greenland
August 3, 2010 09:52 AM - David A Gabel, ENN
Next to Antarctica, Greenland is home to the largest ice sheet on Earth. Scientists in the frigid north of this enormous island have achieved quite an accomplishment by drilling all the way to the bedrock under the ice. On Tuesday, July 27, 2010 at the North Greenland Eemian Ice Drilling site (NEEM), the team completed their drilling to a depth of 2537.36 meters (1.58 miles). The Eemian is an interglacial period, 115,000 to 130,000 years ago, when global temperatures were 2-3 degrees Celsius (3-5 F) higher than they are today. Sea levels were five meters higher, but ice still existed on Greenland. The researchers believe this may useful for predictions of future climates.
Renewable Power Users and Sources
August 2, 2010 03:42 PM - Andy Soos, ENN
Renewable energy is energy which comes from natural resources such as sunlight, wind, rain, tides, and geothermal heat, which are renewable as opposed to fossil fuels for example which once gone are gone. In 2008, about 19% of global final energy consumption came from renewables, with 13% coming from traditional biomass, which is mainly used for heating, and 3.2% from hydroelectricity. The EPA has just named the 50 green power partners (individual purchasing sources or companies) using the most renewable electricity. The Green Power Partnership’s top purchasers use more than 12 billion kilowatt-hours (kWh) of green power annually, equivalent to the annual carbon dioxide (CO2) emissions from the electricity use of more than 1 million average American homes. Green Power users pollute less and do not use up non-renewable sources.
