Study shows alcohol suppresses immune cells, making heavy drinkers more vulnerable to infection
Too much alcohol dulls more than your wits. It also weakens your immune system and could make you much more vulnerable to viruses, including HIV.
To see how alcohol affects resistance to infection, Gyongyi Szabo of the University of Massachusetts Medical School in Worcester and colleagues exposed monocytes – white blood cells involved in the front-line defence against infection – to chemicals that mimic viruses and bacteria. Half of the cells were also soused in the levels of alcohol that a person might have in their blood after quaffing four or five alcoholic drinks daily for a week.
Alcohol blunted the monocytes’ defences. When the over-the-limit cells were exposed to a virus mimic, they produced only a quarter as much of the virus-fighting signalling molecule called type-1 interferon as teetotal monocytes made.
“Interferon is pivotal, the first response to any viral infection,” says Szabo. “There’s no viral elimination without it.”

“If Mars’ gravitational force exerts any influence on our character when we are born, the influence of the gravitational force of a chubby midwife standing three feet from us would be even greater. And the gravitational force of the walls in the operating room would be so significant that they would affect our character for good.”—James S. Trefil on obstetricians and astrology (via cwnl)
“Astrology was discredited 600 years ago with the birth of modern science. To teach it as though you are contributing to the fundamental knowledge of an informed electorate is astonishing in this, the 21st century. Education should be about knowing how to think, And part of knowing how to think is knowing how the laws of nature shape the world around us. Without that knowledge, without that capacity to think, you can easily become a victim of people who seek to take advantage of you”—Neil Degrasse Tyson (via cwnl)
“It has often and confidently been asserted, that man’s origin can never be known: but ignorance more frequently begets confidence than does knowledge: it is those who know little, and not those who know much, who so positively assert that this or that problem will never be solved by science.”—Charles Darwin
So I got to wondering after the whole #occupywallstreet took place and people finally began protesting against the banks and the rich and wallstreet, what’s to happen to that system? What would come after it? Then I remembered the concept of bitcoins which was brought to me before. Below are excerpts from an npr transcript all about bitcoins, their usage, and how they will be able to run side by side the dollar and euro in terms of currency. Check the full transcript as well, it’s a very interesting concept.
If the traders on Mt Gox understand the future, we all may soon see prices online quoted in dollars, euros and bitcoins. Robert Siegel talks about virtual currency “bitcoins” with Annie Lowrey, economy and business reporter for Slate.
Bitcoin is the first de-centralized digital currency. Bitcoins are digital coins you can send through the Internet. Compared to other alternatives, bitcoins have a number of advantages.
Basically, in order to possess a bitcoin, you have to have a program on your computer that can help trade the bitcoins. And then it’s stored on your computer in what’s called a digital wallet. And bitcoins have a value. One bitcoin, according to what it says on Mount Gox today, one bitcoin is a little bit over $7. You can take dollars and purchase bitcoins. Or you can simply purchase bitcoins from anybody who has a bitcoin.
There’s no central banking authority. There really is no banking system that supports this. It’s entirely peer to peer.
“It was just a little more than a century and a half ago when Charles Darwin and Alfred Russel Wallace explained how all the species on Earth could be the product of ancestor- descendant relationships. In was the most important discovery that has been made in science - more important than the discovery that the Earth revolves around the sun, more important than the realization that the Universe is billions of years old, more important even than the discovery of the constituents of the atom. The recognition of biological evolution completely overturned how humans thought about themselves and their relation to the rest of the universe. It’s no wonder that many people still have not reconciled themselves with the implications of evolution”—
