The latest issue of the journal The Gerontologist from The Gerontological Society of America contains 21 articles highlighting the state-of-the-art research regarding aging and technology, and offering guidance for the future.
Muscle co-contraction is a strategy used commonly in elderly people to increase their stability. Co-contraction involves the simultaneous contraction of pairs of muscles from opposing groups to lock a joint and provide stability.
However, co-contraction can also lead to stiffness, which in turn reduces stability, which is why some authors have suggested the opposite approach by pointing to relaxation as a way to improve stability. However, many studies do not clarify whether tension or relaxation is the more effective strategy.
The observed population crash in a colony of sooty terns, tropical seabirds in one of the UK Overseas Territories (UKOTs), is partly due to poor diet, research led by the University of Birmingham has found.
The findings provide fresh evidence of the fragility of marine ecosystems and lend weight to the scientific case for creating the Ascension Island Ocean Sanctuary (AIOS), set to be one of the largest fully protected reserves in the Atlantic Ocean.
Iridium - a rare metal on earth from the meteorite that wiped out dinosaurs - attached to albumin, a protein in our blood, can penetrate into the nucleus of cancer cells and destroy them when blasted with light, researchers at the University of Warwick have found
It can be applied locally and in smaller doses, the next step is pre-clinical trials
"It is amazing that this large protein can penetrate into cancer cells and deliver iridium which can kill them." says Professor Peter Sadler from the Department of Chemistry at the University of Warwick
COLUMBUS, Ohio - During a study spanning nearly a decade, researchers at The Ohio State University College of Medicine, Houston Methodist Research Institute and Houston Methodist Cancer Center have linked the protein clusterin - for the first time -- to many different facets of cardiometabolic syndrome risk through its actions in the liver.
The wonder-material graphene could hold the key to unlocking the next generation of advanced, early stage lung cancer diagnosis.
A team of scientists from the University of Exeter has developed a new technique that could create a highly sensitive graphene biosensor with the capability to detect molecules of the most common lung cancer biomarkers.
In an ongoing study exploring walking for health across the adult lifespan, University of Massachusetts Amherst kinesiology researchers found that walking cadence is a reliable measure of exercise intensity and set simple steps-per-minute guidelines for moderate and vigorous intensity.
Catrine Tudor-Locke, professor of kinesiology, and postdoctoral researchers Elroy Aguiar and Scott Ducharme concluded that for adults, age 21-40, walking about 100 steps per minute constitutes moderate intensity, while vigorous walking begins at about 130 steps per minute.
Many mothers have to navigate a sea of advice from family and experts when it comes to feeding their babies. Nonetheless, nutrition educators typically focus only on the mother, even in Latino communities where grandmothers and other older female relatives often play major roles in caring for children.
A new study shows programs to reduce childhood obesity and other nutrition programs should incorporate all family members who regularly take care of children, not just their mothers.
Around the world 4.2 million people die every year within 30 days after surgery - with half of these deaths occurring in low- and middle-income countries (LMICs), a new study reveals.
There is also a significant unmet need for surgery in LMICs and researchers believe that if operations were provided for all patients who need them the number of global post-operative deaths would increase to 6.1 million.
In one of the coldest, driest places on Earth, CU Boulder scientists have developed a possible answer to a longstanding mystery about the chemistry of streamflow, which may have broad implications for watersheds and water quality around the world.
Wanting to lose weight or get the best deal are not the only influences on what people buy at the grocery store: Religious and moral beliefs also impact the food choices people make.
Researchers from Arizona State University, the University of Wyoming and Oklahoma State University have identified moral beliefs that affect food choices of religious and nonreligious people. The study is currently available online and will appear in the February edition of the Journal of Business Research.
The first moments of life unfold with incredible precision. Now, using mathematical tools and the help of fruit flies, researchers at Princeton have uncovered new findings about the mechanisms behind this precision.
Astronomers using the NASA/ESA Hubble Space Telescope to study some of the oldest and faintest stars in the globular cluster NGC 6752 have made an unexpected finding. They discovered a dwarf galaxy in our cosmic backyard, only 30 million light-years away. The finding is reported in the journal Monthly Notices of the Royal Astronomical Society: Letters.
MINNEAPOLIS, MN- January 31, 2019 - There are more than 290,000 people estimated to be living in the United States with a spinal cord injury. Previously, it has been shown that it is possible to restore some function to young and healthy patients within a few years of injury. Now, researchers show spinal cord stimulation can immediately restore some voluntary movement and autonomic functions such as cardiovascular, bowel, and bladder years after a paralyzing injury without any significant rehabilitation.
Following years of research that demonstrated feeding tubes can harm patients with dementia, the Journal of the American Geriatrics Society has published an OHSU opinion paper recommending patient preference for feeding tubes be excluded from Physician Order for Life-Sustaining Treatment, or POLST, forms.
