Symptoms of Diabetes

A few common symptoms of diabetes include increased thirst and urination, constant hunger, and increased fatigue. Other possible symptoms include weight loss and slow-healing wounds. In the case of type 1 diabetes, symptoms usually develop over a short time; symptoms of type 2 diabetes develop more gradually. Often, type 2 diabetes isn't even diagnosed until a routine blood test.

What Are the Symptoms of Diabetes?

When people have diabetes, the body's cells are locked and the sugar that's in the blood can't enter the cells to give them energy. Since sugar can't get into the cells, it starts to build up in the bloodstream. High levels of blood sugar can lead to the common signs and symptoms of diabetes, including:

Smoking effects on human body

Nicotine is the addictive drug in tobacco smoke that causes smokers to continue to smoke. Addicted smokers need enough nicotine over a day to ‘feel normal’ – to satisfy cravings or control their mood. How much nicotine a smoker needs determines how much smoke they are likely to inhale, no matter what type of cigarette they smoke. 

Along with nicotine, smokers also inhale about 7,000 other chemicals in cigarette smoke. Many of these chemicals come from burning tobacco leaf. Some of these compounds are chemically active and trigger profound and damaging changes in the body. 

There are over 60 known cancer-causing chemicals in tobacco smoke. Smoking harms nearly every organ in the body, causing many diseases and reducing health in general.

In Victoria, it is illegal to smoke in cars carrying children under 18 years of age.

Tobacco smoke contains dangerous chemicals

The most damaging compounds in tobacco smoke include:

·                  Tar – this is the collective term for all the various particles suspended in tobacco smoke. The particles contain chemicals including several cancer-causing substances. Tar is sticky and brown, and stains teeth, fingernails and lung tissue. Tar contains the carcinogen benzo(a)pyrene that is known to trigger tumour development (cancer).

·                  Carbon monoxide – this odourless gas is fatal in large doses because it takes the place of oxygen in the blood. Each red blood cell contains a protein called haemoglobin – oxygen molecules are transported around the body by binding to, or hanging onto, this protein. However, carbon monoxide binds to haemoglobin better than oxygen. This means that less oxygen reaches the brain, heart, muscles and other organs.

What can cause lung cancer?

What can cause lung cancer?

• 85-90% of lung cancer is due to smoking.
• The best way to reduce one’s risk of developing lung cancer and other respiratory conditions is to quit smoking at any age.
• 15-20% of people with lung cancer have never smoked.
• The majority of non-smokers are females.

Risk factors for lung cancer:

• Smoking is the biggest risk factor.
• The more years and larger number of cigarettes smoked the greater the risk of developing lung cancer.
• People who quit smoking decrease their risk of lung cancer over time, but their risk is higher than those who never smoked.
• Second-hand smoke.
• Radon Gas.
• Certain occupations and occupational exposures. 
• Family history may be a risk factor for both those who smoked and those who never smoked.
• The average age of a person diagnosed with lung cancer is late 60s or early 70s, so age is a risk factor.
• Illnesses such as Chronic Obstructive Pulmonary Disease (C.O.P.D.), tuberculosis, asbestosis and silicosis can increase one’s risk of developing lung cancer.

Amylin's Once-Weekly Diabetes Injection Finally Wins FDA Approval

On Friday, the US Food and Drug Administration finally approved Amylin Pharmaceutical's diabetes drug Bydureon, which provides glycemic control for diabetes type 2 in a once-weekly injection. The approval follows two earlier rejections in 2010, when the FDA asked the company to go back and carry out a new trial of the drug's effect on heart rhythm.

The company describes Bydureon (exenatide extended-release for injectable suspension) as the first of its kind. It is a once-a- week version of Byetta, the company's 7-year-old diabetes drug that has to be injected twice a day.

The drug, a glucagon-like peptide-1 (GLP-1) receptor agonist, is approved for use alongside diet and exercise to improve blood sugar control in adults with type 2 diabetes. The company says it will be available in pharmacies throughout the US in February. 

Discovery of New Smell

Scientists have discovered a new smell, but you may have to go to a laboratory to experience it yourself.

The smell is dubbed "olfactory white," because it is the nasal equivalent of white noise, researchers report today (Nov. 19) in the journal Proceedings of the National Academy of Sciences. Just as white noise is a mixture of many different sound frequencies and white light is a mixture of many different wavelengths, olfactory white is a mixture of many different smelly compounds.

In fact, the key to olfactory white is not the compounds themselves, researchers found, but the fact that there are a lot of them.

"[T]he more components there were in each of two mixtures, the more similar the smell of those two mixtures became, even though the mixtures had no components in common," they wrote.
White smell
Almost any given smell in the real world comes from a mixture of compounds. Humans are good at telling these mixtures apart (it's hard to mix up the smell of coffee with the smell of roses, for example), but we're bad at picking individual components out of those mixtures. (Quick, sniff your coffee mug and report back all the individual compounds that make that roasted smell. Not so easy, huh?)

Case Against the Robots With License to Kill

Battlefield drones and robots capable of choosing their targets and firing without any human oversight won't arrive for a few decades, experts say. But a new Human Rights Watch report calls for an international ban on fully autonomous "killer robots" before they ever become a part of military arsenals around the world.

The thousands of drones and robots that the U.S. military already has deployed alongside troops are all controlled remotely by human operators, who can take responsibility if the machines accidentally injure or kill civilians. Fully autonomous robots capable of choosing targets and firing weapons on their own may come online within the next 20 or 30 years, if not sooner.

"Giving machines the power to decide who lives and dies on the battlefield would take technology too far,” said Steve Goose, the Arms Division director at Human Rights Watch. “Human control of robotic warfare is essential to minimizing civilian deaths and injuries."

"Fully autonomous weapons" operating without oversight won't have the artificial intelligence, human judgment or empathy necessary to distinguish between armed soldiers and cowering civilians in murky battlefield conditions, Human Rights Watch says. Its joint report with Harvard Law School's International Human Rights Clinic argues robots could never follow rules of international humanitarian law. [5 Reasons to Fear Robots]
The report released on Nov. 19 suggests the following to stop the "killer robots" future:

• Ban development, production and use of fully autonomous weapons through an international agreement.
