Alcohol Advice Is Alcohol a Drug? Alcohol is often forgotten about when we mention drugs as it’s so accepted and widely available nowadays. Though it may be legal and is usually a counterpart of a good night out, it can still pose the same threats as other less common drugs. I’m sure we all know the short-term effects of alcohol, at worst these are: slurred speech, vomiting, headaches, distorted speech and vision, impaired judgement, memory loss and many more. Thankfully most people know their limits and avoid the longer term effects which are listed below. Long-Term Dangers of Alcohol Alcohol causes more pain and suffering than all other recreational drugs combined. Addiction Fact: The earliest evidence of alcohol drinking is thought to be around 7000BC. Why Do People Drink Alcohol? People have been drinking alcohol for thousands of years. What Steps to take when Drinking How to Tell if You Have an Alcohol Problem If alcohol is beginning to cause problems in your life then there will usually be signs.
A team of scientists hopes to improve the sight of blind people by implanting proteins from spinach leaves into their eyes. When light falls on the proteins, it creates an electrical voltage, which could stimulate healthy regions of the retina and produce meaningful images, they say. "The idea is to insert these proteins into cells in the retina," says Elias Greenbaum of Oak Ridge National Laboratory in Tennessee, US. "If we can do that, we know light can make them produce voltages high enough to stimulate the optic nerve." Greenbaum, who is working on the project with Mark Humayun of the University of Southern California's Doheny Eye Institute, Los Angeles, says the spinach proteins - known as photo-reaction centres - perform a similar task to photoreceptor cells in the retina. Fatty spheres The two now hope to use the photo-reaction centres to replace damaged or diseased photoreceptor cells in blind or partially-sighted people.

Brook Advice Eyeball squeezing could correct sight - 21 March 2002 A light tap on the side of your head could one day restore your eyesight, believe scientists. The tap would tighten a band of artificial muscle wrapped round your eyeballs, changing their shape and bringing blurry images into focus. While the idea has a high 'yuk' factor, the people behind it are confident it will be a safe and effective way to improve vision. Mohsen Shahinpoor and his team at the University of New Mexico call their artificial muscle a "smart eye band". It will be stitched to the sclera, the tough white outer part of the eyeball, and activated by an electromagnet in a hearing-aid-sized unit fitted behind one ear. Most of the eye's focusing is done by the cornea, the hard transparent surface that covers both the pupil and the iris; the lens is responsible only for fine-tuning. If the cornea or lens do not focus strongly enough or the eyeball is too short, the light will focus behind the retina, blurring images of close-up objects. Elongated eyeball Click and read

Germans Manufacture Artificial Blood Vessels With a 3-D Printer From intestines to tracheas, tissue engineers are building a handful of new body parts — but progress on larger organs has been slow. This is mainly because tissues need nutrients to stay alive, and they need blood vessels to deliver those nutrients. It's difficult to build those vascular networks, but now a team from Germany may have a solution: Print some capillaries with a 3-D printer. Engineers at the Fraunhofer Institute for Interfacial Engineering and Biotechnology IGB developed special printer inks containing synthetic polymers, as well as biomolecules that will prevent the artificial tissue from being rejected. Chemical reactions turn the printed material into an elastic solid, allowing the researchers to build highly precise three-dimensional structures. Though 3-D printing can be quite detailed, the researchers needed an extra layer of precision to build the fine, feathery structures to serve as capillaries. [via BBC]
untitled What damage does alcohol do to our bodies? 2 October 2011Last updated at 00:08 By Philippa Roxby Health reporter, BBC News We know that drinking too much alcohol is bad for us. It gives us hangovers, makes us feel tired and does little for our appearance - and that is just the morning afterwards. Long term, it increases the risk of developing a long list of health conditions including breast cancer, oral cancers, heart disease, strokes and cirrhosis of the liver. Research shows that a high alcohol intake can also damage our mental health, impair memory skills and reduce fertility. The direct link between alcohol and the liver is well understood - but what about the impact of alcohol on other organs? Numerous heart studies suggest that moderate alcohol consumption helps protect against heart disease by raising good cholesterol and stopping the formation of blood clots in the arteries. Toxic However, drinking more than three drinks a day has been found to have a direct and damaging effect on the heart. Continue reading the main story
15 Brain Foods To Boost Focus and Memory What does the food you eat have to do with how your brain functions? Turns out an awful lot. While we’ve always known that what we eat affects our bodies and how we look, scientists are also learning more and more that what we eat takes a toll on our brains. Yes, brain foods matter (especially for our gray matter). See, our bodies don’t like stress. These little chemicals prompt the immune system to kick in and fight back against the stress through inflammation, as though stress is an infection. But what does this all have to do with food? Plus, brain foods rich in antioxidants, good fats, vitamins and minerals provide energy and aid in protecting against brain diseases. See these 15 powerful brain foods used to boost focus and memory.
