Global Warming And Your Health
Although heat related illnesses and deaths will increase with the
temperatures, climate change is expected to also attack human health
with dirtier air and water, more flood-related accidents and injuries,
threats to food supplies, hundreds of millions of environmental
refugees, and stress on and possible collapse of many ecosystems that
now purify our air and water.

Diabetes Gene Carries Similar Risk To Obesity
Carrying two copies of a common variant of a particular gene
doubles your chances of developing diabetes and puts you in a similar

Many Seizure-Prone People Continue to Drive
University of Florida researchers surveyed more than 300 epilepsy
patients in northeast Florida and southeast Georgia. They found that
nearly 20 percent of those who had at least one seizure a year drove.
Even more alarming, nearly 25 percent of patients who suffered daily
seizures still drove occasionally.

Threat From Plummeting Biodiversity Qualified
Accelerating rates of species extinction will pose substantial
problems for humanity in the near future, since biodiversity is
intrinsically linked to the ecological "services" that nature provides
to humanity. Think of composting, pest control, sequestering of
pollutants and the absorption of greenhouse gases.

Extensively Drug-resistant Tuberculosis Is Emerging Threat
Risk of tuberculosis disease is greatly increased in people with
HIV infection, and multidrug-resistant (MDR) tuberculosis is emerging
as a major cause of death in these patients. The term extensively
drug-resistant (XDR) tuberculosis has recently been used to describe
strains that are resistant to second-line drugs—i.e., drugs that are
used if the recommended first drug treatment regimen fails.

Plutonium Or Greenhouse Gases? Weighing The Energy Options
Can nuclear energy save us from global warming? Perhaps, but the
tradeoffs involved are sobering: thousands of metric tons of nuclear
waste generated each year and a greatly increased risk of nuclear
weapons proliferation or diversion of nuclear material into terrorists'
hands. University of Michigan professor Rodney Ewing shows that nuclear
power generation would need to increase by a factor of three to ten
over current levels to have a significant impact on greenhouse gas
emissions. We currently have 400-plus nuclear reactors operating
worldwide, and we would need something like 3,500 nuclear power plants.
Even if they could be built and brought online quickly, that many power
plants would generate tens of thousands of metric tons of additional
nuclear waste annually. So the real question is: "Plutonium versus
carbon---which would you rather have as your problem?"

Gene variation affects risk of chronic pain
A new NIH-funded study shows that a specific gene variant in humans

volunteers and the risk of developing chronic pain after one kind of
back surgery. Blocking increased activity of this gene after nerve
injury or inflammation in animals prevented development of chronic pain.

Do the risks of eating fish outweigh the benefits? Yes
Fish is high in protein and omega-3 fatty acids. But concerns have
been raised in recent years about chemicals found in fish from
environmental pollution, including mercury, PCBs and dioxins. That has

New Analytical Tool Developed For Liquid Explosives Detection

Protecting virus offers instant flu protection & converts flu
infections into their own vaccines
Professor Nigel Dimmock at the University of Warwick has spent more
than two decades investigating an entirely new method, that uses a
‘protecting virus’, which has a a huge but specific deletion in one of
the virus’s genes. This deletion makes the virus harmless and prevents
it from reproducing by itself within a cell, so that it cannot spread
like a normal influenza virus. However, if it is joined in the cell by
another influenza virus, it retains its harmless nature but starts to
reproduce-and at a much faster rate than the new influenza virus. This
fast reproduction rate-spurred by the new flu infection-means that the
new invading influenza is effectively crowded out by the ‘protecting
virus’. This vastly slows the progress of the new infection, prevents
flu symptoms, and gives the body time to develop an immune response to
the harmful new invader. In effect the protecting virus converts the
virulent virus into a harmless live vaccine.
