Fast-spreading killers: how Ebola compares with other diseases

HOMELAND SECURITY NEWS WIRE                            Nov. 1, 2014
By Mick Roberts

The West African outbreak of Ebola has claimed more than 4,800 lives and this number is sure to rise. There is understandably a lot of fear about Ebola, but how does it actually compare with other fast-spreading infectious diseases?

Models overestimate Ebola cases

Rate of infection in Liberia seems to plateau, raising questions over the usefulness of models in an outbreak

The Ebola outbreak in West Africa has infected at least 13,567 people and killed 4,951, according to figures released on 31 October by the World Health Organization (WHO). Now, in a rare encouraging sign, the number of new cases in Liberia seems to be flattening after months of exponential growth. Scientists say it is too soon to declare that the disease is in retreat: case data are often unreliable, and Ebola can be quick to resurge. But it is clear that mathematical models have failed to accurately project the outbreak’s course.

Researchers are now struggling to understand whether reports of empty beds at treatment centres and declining burial numbers are signs that fewer people are developing Ebola, or whether cases and deaths are going unrecorded.....

Researchers Study Ebola Link to Gene in Rare Disease

WALL STREET JOURNAL                             Nov 3, 2014

By Amy Dockser Marcus

In the search for answers about Ebola, researchers are starting to look at an unexpected group of people: parents of children who have the rare but fatal genetic disease Niemann-Pick Type C.

Blood and tissue samples from Hugh and Chris Hempel of Reno, Nev., whose children have a rare disease, may help in ongoing Ebola research. Hempel family

The intersection between research in Ebola and NPC disease was surprising, and came after two scientific papers were published in 2011 demonstrating that a protein made by the same gene related to NPC disease is essential for Ebola infection.

Ebola uses the so-called NPC1 protein made by the gene to get into the cell and replicate the virus.

Now, research suggests that the gene that causes NPC disease may also offer protection against Ebola.

Ebola-carrying bats may be heroes as well as villains

By Ben Hirschler

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.

NATURE SCIENCE International Weekly Journal of Science                                   Oct. 29, 2014

By Erika Check Hayden

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

 submitted by Luis Kun

      

"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)

futurity.org - by Mike Williams-Rice - June 11, 2014

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.
