Finger pricks and daily insulin injections are currently the leading regimen for those with type 1 diabetes, a condition in which the body’s insulin producing cells beta cells are destroyed. And it’s not foolproof.
Patients can often face risks over overcorrecting their blood sugar levels, which can potentially lead to hypoglycemia – low blood sugar – and coma.
Insulin is responsible for regulating the amount of sugar in the blood, and dysfunctions with it can cause diabetes.
In an experiment with global implications, Australian scientists have successfully wiped out more than 80% of disease-carrying mosquitoes in trial locations across north Queensland.
The experiment, conducted by scientists from the Commonwealth Scientific and Industrial Research Organization (CSIRO) and James Cook University (JCU), targeted Aedes aegypti mosquitoes, which spread deadly diseases such as dengue fever and Zika.
In JCU laboratories, researchers bred almost 20 million mosquitoes, infecting males with bacteria that made them sterile. Then, last summer, they released over three million of them in three towns on the Cassowary Coast.
Inhibiting TORC1 might boost the immune system of the elderly.
In a recent study conducted by researchers at the Novartis Institutes for Biomedical Research in Massachusetts, inhibition of mTOR complex 1 boosts the immune system of aged people, decreasing their yearly rate of infections as well as increasing their response to an influenza vaccine [1].
Study summary
Scientists at the California Institute of Technology can now assess a person’s intelligence in moments with nothing more than a brain scan and an AI algorithm, university officials announced this summer.
Caltech researchers led by Ralph Adolphs, PhD, a professor of psychology, neuroscience and biology and chair of the Caltech Brain Imaging Center, said in a recent study that they, alongside colleagues at Cedars-Sinai Medical Center and the University of Salerno, were successfully able to predict IQ in hundreds of patients from fMRI scans of resting-state brain activity. The work is pending publication in the journal Philosophical Transactions of the Royal Society.
Adolphs and his team collected data from nearly 900 men and women for their research, all of whom were part of the National Institutes of Health (NIH)-driven Human Connectome Project. The researchers trained their machine learning algorithm on the complexities of the human brain by feeding the brain scans and intelligence scores of these hundreds of patients into the algorithm—something that took very little effort on the patients’ end.
A disclaimer on the new article that I wrote: while I do think the Beta-amyloid plaque plays a key role in the development of Alzheimer’s disease I do not think it’s the only thing. I’ll be writing more on Alzheimer’s disease as I study more.
The abnormal accumulation β-amyloid peptide is the leading candidate for the cause of Alzheimer’s disease is currently ranked the 6 th leading cause of death in the United States while some statistics claim it may rank as high as the third leading cause of death.
What is Alzheimer’s disease?
Alzheimer’s is a slowly progressive disease that causes the loss of memories and cognitive function. It is the most common form of dementia and accounts for 60 to 80% of cases.
It’s in a bad taste to say that other global issues are more urgent than ageing, when pretty much all global issues—ageing included—affect the life, and the quality of life, of many people.
Suppose you’re in your mid-seventies, and you find out that your aortic valve doesn’t work very well. Undergoing a replacement operation—nowadays, a relatively simple and safe procedure—is not only going to help you with your unpleasant episodes of fatigue, chest pain, and dizziness, it may well save your life, minimizing your risk of sudden cardiac arrest.
Your doctor suggests that you undergo the procedure and sends you to a surgeon for the operation; however, when you get there, the surgeon starts yelling at you that, rather than using resources to replace your valve and extend your life, we should fund initiatives to save children in poor countries, build health clinics, train midwives, and fight for equal opportunity and for women’s rights. He then goes on rambling that, until these issues are addressed, he doesn’t want to hear about extending your natural lifespan—after all, since you’re in your mid-seventies, you’re well above the world’s average lifespan; he shoos you and your family out and slams the door on you.
The chances are good that you’d think this person was several sandwiches short of a picnic; you would report him and have him fired for malpractice. Thankfully, you’re not very likely to run into a surgeon like that, but you are likely to bump into people contending the exact same things as the mad surgeon when you replace heart surgery—a very specific form of life extension—with the general concept of life extension. Why is that?
Pills hailed as the first real “anti-aging” drugs inched a little closer to the market after a study found they cut the number of respiratory infections in the elderly by half.
The drugs: The pills act on an aging-related pathway called TORC1. Inhibiting this pathway “has extended life span in every species studies to date” (like mice and worms), according to Joan Mannick, who lead the study for drug giant Novartis.
Will humans live longer, too? Maybe. But that will take time to figure out. For now, what’s known is that giving people 65 and older these drugs seems to boost their immune function. Elderly people taking the drugs got about 40 percent fewer colds or bronchial infections. About 264 people got the drugs over six weeks and then were tracked for a year.
