Want to live longer? Lift weights: People with weaker muscles are 50 percent more likely to die early, study suggests

  • As the American population ages, rates of disability climb 
  • Disability and a loss of independence detract from both quality and length of life 
  • A new study found that nearly half of Americans have poor grip strength
  • Poor grip strength is a trusted measure of overall strength as well as longevity 
  • The University of Michigan researchers found that weak muscles - regardless of muscle mass - were linked to a 50 percent higher risk of early death 
If you want to up your odds of living a longer, healthier life, you might want to consider lifting weights. 
People who have strong muscles are more likely to reach an older age than weaker peers, according to new research from the University of Michigan. 
The researchers say that it's never too late to take up muscle-building workouts - and may even be most important for older people to work on strength training than it is for younger ones. 
But don't worry about bulking up: the study authors found that it's muscle strength, not mass, that makes a difference for longevity. 
Building up muscle strength - especially in your grip - can help reduce the risk of  an early death, while those whose hands are weak are 50 percent more likely to die early, a study finds

Americans are aging. The baby boomers make up 20 percent of the American population and within the next decade, they will all reach senior status.  
Already, nearly half of all adults over 65 live with a disability that makes living on their own difficult. Soon, even more will need assistance. 
There is nothing to do to stop aging, but staying strong can dramatically reduce the effects of age and its burden on society. 
We know that good diets and generally remaining active have protective effects against heart disease, diabetes and even cancer. 
But the latest research shows that we would be wise to focus not just on exercises that get our heart rates up, but on weight lifting too. 
'Maintaining muscle strength throughout life - and especially in later life - is extremely important for longevity and aging independently,' said lead study author Dr Kate Duchowny. 
And among the most important parts to keep strong are our hands, according to Dr Duchowny and her team. 
There aren't a lot of workout programs designed just for hands, but grip strength is a key measure of overall strength and decline as people get older. 
It's easy to forget, but hands are key to just about every function of independent living: bathing and dressing oneself, cleaning, cooking, even handling objects.  
The University of Michigan team analyzed grip strength of more than 8,300 men and women that take part in their Health and Retirement study. 
Nearly half - 46 percent- of the study participants had hand grip strengths that fell in to the 'weak muscle' category, 
And that number was significant: according to the University of Michigan study, previous work has suggested that only some 13 percent of the American senior population has such poor strength. 
But the Health and Retirement study group was meticulously designed to be more representative of the demographics of the US and, once those populations were included, the number of older people with weak muscles multiplied. 
Using their more diverse sample, the University of Michigan team established their own unique threshold points by which to define muscle weakness. 
'We believe our cut-points more accurately reflect the changing population trends of older Americans and that muscle weakness is a serious public health concern,' said Dr Duchowny.
'Many aging studies—not just those on muscle strength—are conducted on largely white populations. However, as the U.S. population becomes increasingly diverse, it is critical to use nationally representative data for these types of studies.' 
Even after accounting for other variables like smoking, survival times dropped off dramatically with diminished muscle strength.  
People who met the 'weak' muscle threshold were more than 50 percent more likely to die an early death than stronger individuals were.  
'Many aging studies—not just those on muscle strength—are conducted on largely white populations. However, as the U.S. population becomes increasingly diverse, it is critical to use nationally representative data for these types of studies,' said Dr Duchowny. 
'Having hand grip strength be an integral part of routine care would allow for earlier interventions, which could lead to increased longevity and independence for individuals.'

Apple patents non-invasive device that constantly checks blood glucose levels through a sensor on its watch



  • Apple filed a patent for a system that can measure substances without contact
  • It describes a system where a 'compact, portable device' is attached with sensors, light emitters, filters and other objects to prevent inaccuracies
  • The firm has been rumored for more than a year to be building a non-invasive glucose monitoring device, described as the 'holy grail' of life sciences
The iPhone maker filed a patent Thursday titled 'Reference switch architectures for noncontact sensing of substances,' which many believe could be a prototype design for Apple's rumored glucose monitoring technology. 
It describes a system where a 'compact, portable electronic device' could be fitted with technology that's capable of measuring the type or levels of a certain substance.
Apple has been rumored for several months to be developing non-invasive glucose monitoring technology for the Apple Watch. 

Apple may be developing a revolutionary device for people who suffer from diabetes. A new patent describes a system where a 'compact, portable electronic device' could be fitted with technology that's capable of measuring the type or levels of a certain substance

IS APPLE DEVELOPING A GLUCOSE SENSOR? 

Apple has reportedly hired a team of biomedical engineers to develop non-invasive sensors which could detect diabetes and monitor blood-sugar levels.
The engineers are expected to work at a nondescript office in Palo Alto, around 15 miles away from the new corporate headquarters in Cupertino, California.
If the non-invasive sensors come to fruition, it would be a breakthrough moment for medical science.
The late Apple CEO Steve Jobs envisaged the devices as another form of wearable technology, similar to a smartwatch or fitness monitor.An optical imaging system is used to perform absorption spectroscopy, or 'remote sensing,' where measurements are able to be collected due to two objects being in close proximity to one another.  
Apple notes that there's a possibility for measurement inaccuracies, so it proposes an apparatus that includes a beamsplitter, or an 'optical component that can split a beam of light into multiple beams of light.' 
The apparatus would also include short-wavelength infrared detectors, light emitters, filters and other objects to prevent inaccuracies. 
The patent doesn't describe what types of substances the device would measure. 
'Examples of the disclosure can include measuring a concentration of a substance in a sample at a sampling interface,' the filing states. 
'In some examples, the sample can include at a least a portion of a user, where additional information can be used to improve the delivery of measured information, analysis, or any other content that may be of interest to the users.'
Speculation began building in 2017 that Apple was building a non-invasive glucose monitor. Apple has been rumored for several months to be developing non-invasive glucose monitoring technology for the Apple Watch. A new patent could describe how that system would work

A report from CNBC stated that Apple has a 'super secret' team of engineers working on the project, which began over five years ago.
The team has been conducting feasibility trials as it works to gain regulatory approval and may test it at clinical sites around San Francisco, CNBC noted. 
Additionally, last May Apple CEO Tim Cook was testing a glucose monitor that attaches to the Apple Watch. 
The device has been described as the 'holy grail' of life sciences, because it's difficult to monitor blood sugar without breaking the skin.
The project - envisioned by co-founder Steve Jobs before his death - could lead to 'breakthrough' wearable devices that detect the disease and monitor blood-sugar levels.

Apple has hired a team of biomedical engineers as part of the secret initiative, according to reports in CNBC.
Up to 30 people are believed to be working on the project, which has be running for five years.
The researchers have been tasked with developing bio-sensors to monitor blood sugar levels.
Currently this involves taking regular blood samples, which can involve anything from a thumb-prick test to intravenous extraction

The END of painful finger-prick tests for diabetics? Scientists create a new sticky patch that can read blood sugar levels through your skin (and it could link up to your smartphone one day!)


  • The pioneering new device has been developed by Bath University scientists
  • It sticks onto the skin to test glucose levels - and doesn't require a drop of blood
  • Experts hope hoped the skin patch could one day be linked to a smartphone app
  • They found it was accurate after testing it on pigs and two human volunteers

Painful finger-prick blood tests taken several times a day by millions of diabetics could become a thing of the past.
A pioneering new patch that sticks onto the skin to test glucose levels has been created by scientists.
The device, developed by Bath University researchers, works by assessing sugar levels in the skin through hair follicles - not blood.
It is hoped the skin patch could one day be linked to a smartphone app to warn diabetics when to take action. 
The patch, if proven in larger trials, could replace the current method, considered unpopular, to test sugar levels.

Professor Richard Guy and colleagues found the patch was accurate after testing it on pigs and two human volunteers. 
He said: 'A non-invasive - that is, needleless - method to monitor blood sugar has proven a difficult goal to attain.
'The closest that has been achieved has required either at least a single-point calibration with a classic "finger-stick", or the implantation of a pre-calibrated sensor via a single needle insertion.'
Professor Guy added the new monitor 'promises a truly calibration-free approach'.

WHAT ARE THE FIVE NEW TYPES OF DIABETES?

For decades the disease has been considered to be two different forms - type one, an autoimmune disease in which people stop producing insulin, and type two, in which the body becomes resistant to insulin.
But now a major project in Sweden and Finland has found type two diabetes should actually be categorised as four different diseases.
The researchers, led by experts at Lund University, said the findings should prompt a ‘paradigm shift’ in the way people treat diabetes.
Cluster 1. Severe Autoimmune Diabetes- which until now has been known as ‘type one’ diabetes - is an autoimmune disease in which people stop producing insulin. Usually strikes in childhood but can emerge in adults. Requires insulin injections for life.
Cluster 2. Severe Insulin-Deficient Diabetes - young people often misdiagnosed as having type one, but whose immune systems are fine. Actually a variant of type two diabetes, but often of a healthy weight. High blood sugar, low insulin production and moderate insulin resistance.
Cluster 3. Severe Insulin-Resistant Diabetes - is predominantly linked to obesity and severe insulin resistance.
Cluster 4. Mild Obesity-Related Diabetes- includes obese patients, but is less serious and includes people who fall ill at a relatively young age.
Cluster 5. Mild Age-Related Diabetes is the largest group, with 40 per cent of all patients, and consists mostly of elderly patients.He continued: '[It is] an essential contribution in the fight to combat the ever-increasing global incidence of diabetes.' 

The electrical patch, which sits on the wrist, taps into glucose in the skin through an array of miniature sensors.
It measures blood sugar without piercing the skin by drawing glucose from fluid between cells across hair follicles.
Glucose collects in tiny reservoirs where it is measured, with the ability to take readings every ten to 15 minutes over several hours.
The adhesive skin patch is more accurate than that of other experimental patches because it can operate on a much smaller area. 
The team initially tested the patch on pig skin, which showed it could accurately track glucose levels across the range seen in diabetic human patients.
Further tests on two human volunteers, published in Nature Nanotechnology, again showed it could track blood sugar variations throughout the day.
Professor Guy and colleagues hope to improve the design of the patch to allow for full functionality across a 24-hour period and carry out clinical trials.
Diabetes is rapidly becoming Britain’s fastest growing health crisis, with the number of patients doubling in 20 years to 3.7 million.
The majority of cases are type 2, which is considered a hidden killer that can lead to heart failure, blindness, kidney disease and amputations.  
Dr Adelina Ilie, study co-author, said: 'The specific architecture of our array permits calibration-free operation and it has the further benefit of allowing realisation with a variety of materials in combination.
'We utilised graphene as one of the components as it brings important advantages.
'Specifically, it is strong, conductive, flexible, and potentially low-cost and environmentally friendly.
'In addition, our design can be implemented using high-throughput fabrication techniques like screen printing, which we hope will ultimately support a disposable, widely affordable device.'
