LONDON - Bats are living up to their frightening reputation in the world's worst Ebola outbreak as prime suspects for spreading the deadly virus to humans, but scientists believe they may also shed valuable light on fighting infection.

Bats can carry more than 100 different viruses, including Ebola, rabies and severe acute respiratory syndrome (SARS), without becoming sick themselves.

While that makes them a fearsome reservoir of disease, especially in the forests of Africa where they migrate vast distances, it also opens the intriguing possibility that scientists might learn their trick in keeping killers like Ebola at bay.

The Ebola questions

Scientists know a lot about the virus that causes Ebola — but there are many puzzles that they have yet to solve.

Scientists know a lot about the virus that causes Ebola — but there are many puzzles that they have yet to solve.

An Ebola virus particle from the 2014 outbreak.

To much of the world, the virus behind the devastating Ebola outbreak in Africa seems to have stormed out of nowhere. But Leslie Lobel thinks we should have seen it coming.

In 2012, Lobel and a team of researchers spent six months in Uganda studying the Ebola virus and related viruses. Over the course of their stay, these pathogens caused at least four separate outbreaks of disease in central Africa, affecting more than 100 people. To Lobel, a virologist at Ben-Gurion University of the Negev in Beer-Sheva, Israel, the outbreaks felt like the small tremors that can precede a major earthquake. “We all said, something is going on here; something big is going to happen,” he says.

Assessing the Science of Ebola Transmission

THREE ARTICLES DESCRIBING DETAILS OF THE EBOLA VIRUS AND OTHER VIRUSES.

Advances in microscopy have allowed scientists like Sriram Subramaniam and colleagues at the National Cancer Institute to look at the workings of tiny viruses. In this case, microscopy was used to illustrate the complex process in which human cells infected with HIV-1, green and blue, are linked to uninfected cells.

Americans by 2 to 1 Would Pay More to Curb Climate Change

Americans are willing to bear the costs of combating climate change, and most are more likely to support a candidate seeking to address the issue.

By an almost two-to-one margin, 62 percent to 33 percent, Americans say they would pay more for energy if it would mean a reduction in pollution from carbon emissions, according to the Bloomberg National Poll.

Handheld Terahertz Cameras Could Replace MRI

"With this technology, you could conceivably design a handheld terahertz detection camera that images tumors in real time with pinpoint accuracy. And it could be done without the intimidating nature of MRI technology," says Junichiro Kono. (Credit: Sandia National Laboratories)

Scientists have used carbon nanotubes to create compact terahertz sensors that operate at room temperature.

The technology could make screening bags and passengers at airports less intrusive. It also has the potential to inspect food and even scan for tumors.

Junichiro Kono, a physicist at Rice University, says the potential to replace magnetic resonance imaging (MRI) technology in screening for cancer and other diseases is one of the most exciting possible applications.

thedrum.com - April 14th, 2014 - Ishbel MacLeod

Tsunami warnings were issued over the weekend following an earthquake on the Solomon Islands, leading to over 15,000 tweets mentioning the warnings. So, how does social media impact weather warnings?

Last year, Twitter launched an alerts system, which allows users to get notifications directly to their phones during emergencies whenever a credible organisation account - such as police or the fire brigade - marks a tweet as an alert.

H.R. 6, the Domestic Prosperity and Global Freedom Act

energycommerce.house.gov - April 4th, 2014

In response to Russia’s recent aggression and DOE’s slow export approval process, Rep. Cory Gardner (R-CO) introduced H.R. 6 to expedite exports of U.S. liquefied natural gas (LNG) to our allies.

H.R. 6, the Domestic Prosperity and Global Freedom Act, provides that all pending LNG export applications for which a notice has been published in the Federal Register as of March 6, 2014, will be granted without delay.

The legislation also modifies the standard of review for future export applications, shifting the benchmark from Free Trade Agreement (FTA) countries to World Trade Organization (WTO) members.

Different Network Structures in Twitter Maps

      

plexusinstitute.org - by Prucia Buscell - March 27, 2014

Twitter conversations create identifiable networks that have structural differences depending on the topic and the influence of dominant individuals. The structures are created as participants in the network choose the people they answer, retweet, and mention in their own messages, according to the Pew Research Internet Project.

The Pew researchers found six identifiable network structures: divided, unified, fragmented, clustered, and inward and outward hub and spoke structures. The report summary contains explanations and examples of teach type.

Sea, Lake, and Overland Surges from Hurricanes (SLOSH)

nhc.noaa.gov

SLOSH Model - Introduction

The Sea, Lake and Overland Surges from Hurricanes (SLOSH) model is a computerized numerical model developed by the National Weather Service (NWS) to estimate storm surge heights resulting from historical, hypothetical, or predicted hurricanes by taking into account the atmospheric pressure, size, forward speed, and track data. These parameters are used to create a model of the wind field which drives the storm surge.

The SLOSH model consists of a set of physics equations which are applied to a specific locale's shoreline, incorporating the unique bay and river configurations, water depths, bridges, roads, levees and other physical features.
