Is the ebola outbreak caused by deforestation?

are we making ebola worse by cutting down the forests?

I have no idea, except to note that there was a lot of deforestation when they cut the forest to start plantations.

and it's unclear if the deforestation is to replant other crops, illegal logging for export, or if it's poor people who cut down/burn down forests to plant (and then move on after five years when the soil is degraded by their crops).

 Villages here are surrounded by forest and agriculture, and that means bats—thought to carry Ebola—are everywhere. "I lived in a house in a village in Kissidougou district for two years which was full of bats in its roof," she says.
Human activity is driving bats to find new habitats amongst human populations. More than half of Liberia's forests—home to 40 endangered species, including the western chimpanzee—have been sold off to industrial loggers during President Ellen Johnson Sirleaf's post-war government, according to figures released by Global Witness. Logging, slash-and-burn agriculture, and chopping down trees for an increased demand for fire wood are all driving deforestation in Sierra Leone, where total forest cover has now dropped to just 4 percent, according to the United Nations Environment Programme (UNEP) which says if deforestation continues at current levels, Sierra Leone's forests could disappear altogether by 2018.

but then they mix up the human version of ebola with the Ebola Reston, which does not affect humans (or if humans get infected, they don't get very sick).

Ebola in the United States?In 1989, Ebola was detected in monkeys imported from the Philippines at quarantine facilities in Virginia and Pennsylvania, with no human patients. The following year, the same thing happened again in Virginia and Texas. Four humans developed antibodies, but did not get sick. And then again in 1996 in Texas, monkeys from the Philippines were found to have Ebola, but yet again there were no human infections.

Time to update your polio shot

 The CDC warns: If you plan to travel to Asia/Africa, you now need to renew your polio shot...

thanks to the anti vaccine hysteria (ye, it's the mullahs fault, but a lot of them got the idea from reading the anti vaccine hysteria in the UK papers).

Advisory Committee on Immunization Practices (ACIP) and CDC recommendations are evidence-based and provide public health recommendations to the general public on the basis of the best available epidemiological and scientific data to prevent poliovirus infection. This includes recommendations for travelers visiting countries with WPV circulation in the last 12 months or countries and provinces where they will be in situations with a high risk for exposure to persons with imported poliovirus infection.
Three countries are still endemic for polio (Afghanistan, Nigeria, and Pakistan). Countries where WPV has circulated during the previous 12 months include those endemic countries and those with polio outbreaks or environmental evidence of active WPV circulation during this time (Cameroon, Ethiopia, Equatorial Guinea, Iraq, Israel, Somalia, and Syria). Travelers working in health-care settings, refugee camps, or other humanitarian aid settings in these and neighboring countries might be at particular risk for exposure to WPV.

but there's more:

U.S. clinicians should be aware of possible new vaccination requirements for patients planning travel for >4 weeks to the 10 countries identified by WHO as polio-infected (Figure) (13). Four countries (Cameroon, Equatorial Guinea, Pakistan, and Syria) are now designated as "exporting wild poliovirus." Those countries should "ensure" recent (4–52 weeks before travel) polio boosters among departing residents and long-term travelers (of >4 weeks). An additional six countries (Afghanistan, Ethiopia, Iraq, Israel, Nigeria, and Somalia) are designated as "infected with wild poliovirus." Those countries should "encourage" recent polio vaccination boosters among departing residents and long-term travelers. This list might change when the public health emergency of international concern is reassessed at the end of July, and, for some countries, these measures could extend beyond the 3 months validity of these temporary recommendations. 

so one of the side effects of the Syrian civil war is that you could catch polio if you go to Israel...

regrowing corneas

uk Mail article


They have identified a way to enhance regrowth of human corneal tissue to restore vision, using a molecule known as ABCB5, which acts as a marker for hard-to-find limbal stem cells. The research, published in the journal Nature, is also one of the first known examples of constructing a tissue from an adult-derived human stem cell. Limbal stem cells are found in the eye’s basal limbal epithelium, or limbus, and help maintain and regenerate corneal tissue.

HOW THEY DID IT

Using a high-tech 'bio-printer', the researchers fabricated a multitude of interconnected tiny fibres to serve as the mold for the artificial blood vessels.
They then covered the 3D printed structure with a cell-rich protein-based material, which was solidified by applying light to it.
Lastly they removed the bio-printed fibres to leave behind a network of tiny channels coated with human endothelial cells, which self organised to form stable blood capillaries in less than a week.
The study reveals that the bioprinted vascular networks promoted significantly better cell survival, differentiation and proliferation compared to cells that received no nutrient supply.

EBOLA EPIDEMIC

UKTelegraph article

Ebola 'out of control' in West Africa as health workers rush to trace 1,500 possible victims
Fear, mistrust of Western medicine and difficulties reaching remote areas mean hundreds of potentially infected people have not yet been found

yes: Like HIV, which is spread when needles etc are reused without proper sterilization (and disposable needles are expensive), Ebola in a hospital actually results in spreading it to medical personnel, family, and visitors.

Ebola is transmitted by coming into contact with bodily fluids of an infected person. It has no cure and as many as 90 per cent of its victims die, often from uncontrollable internal and external bleeding. 
 When we had a cholera epidemic, we set up clinics at the local schools to care for them, but that needs running water to wash with.

In traditional Africa, when smallpox affected people, often they were isolated in a hut and someone left food and water at the doorway....if they didn't get it, after so many days, the hut was burned down.

On the other hand, when everyone with the disease dies in the hospital, the locals recognize that it's no use to take sick people there. And when the medical personnel from outside are often of different races and cultures, it takes awhile to get trusted. Often small things make a person look crazy or impolite or excessively bossy, and of course there is resentment against colonial days.

For example, when Sister Patricia would come into a ward and see something she'd order a nurse to clean it up etc....and the nurse would turn to her with lowered eyes and say: Good morning sister how are you.

Because a visitor has to go through the greetings before they get to the reason for their visit.

Nor is this only in Africa: some smart Americans in the Iran hostage crisis many years ago used to do this to put off the train of thought of their interrogators, i.e. changing from western questioning to traditional discussions.

Another problem: cleaning the body for burial also spreads the disease.That means carrying the body home in a car (costs money).

A third problem: The people don't want to die among strangers, far from their homes.

We love them, we really do. But sometimes our cats drive us crazy. These monsters do exactly what they want and sometimes see us as their slave instead of their loving owner. And still it is super cosy to have one in your house. But every cat comes with his own habits. Some only drink out of your glass and some have a special spot on the couch. This is a whole list of cat habits that cat owners will understand:


Trauma kills kids

In 2010 alone, the top three causes of death for those aged between one and 30 were unintentional injury, suicide, and homicide. Almost four fifths of deaths among people in this age group were due to injuries, with only one fifth due to chronic diseases and only 1% due to infectious diseases. In 2010, among people of all ages, 121,000 died due to unintentional injuries, including automobile crashes, poisoning, and suffocation. Rates of suicide and homicide are unequally distributed across groups, the report found. Suicides were twice as common as homicides (38,364 deaths in 2010 alone, versus 16,259). The highest rates of suicide are found in Native American and Alaskan Natives (16.9 per 100,000) and non-Hispanic whites (14.9). Homicide rates for African Americans (18.6) were double those of the nearest group (Native Americans and Alaskan Natives) and several times higher than other groups. Large disparities between men and women were also observed in the rates of suicide (19.8 vs 5.0) and homicide (8.3 vs 2.2).

well, maybe someone should make movies and video games less violent.

The real problem is that these films JUSTIFY the violence as the only solution for a problem (you are bullied/dissed/stolen from/injured: so get them back).

So where are the films with forgiveness?

New compound that could work for malaria

Science daily

Source: Walter and Eliza Hall Institute Summary: Researchers are homing in on a new target for malaria treatment, after developing a compound that blocks the action of a key 'gatekeeper' enzyme essential for malaria parasite survival. The compound, called WEHI-916, is the first step toward a new class of antimalarial drugs that could cure and prevent malaria infections caused by all species of the parasite, including those resistant to existing drugs
