In the war on antibiotic-resistant bacteria, it’s not just the antibiotics that are making the enemy stronger but also how they are prescribed. A new study suggests that doctors can beat antibiotic resistance using those same antibiotics but in a very targeted manner and in combination with other health strategies. The current broad application of antibiotics helps resistant bacterial strains evolve forward. But using data about...

Multiple brain regions moderate and link depressive mood and pain
by University of California – San Diego Depression is linked to diminished activity in parts of the brain believed to regulate mood, which previous research suggests may explain why depressed persons display an lessened ability to govern their ruminative thought process. In a new paper published online in advance of print, researchers at University of California San Diego School...

Researchers release first 3D model of human cell division
Scientists at the Allen Institute for Cell Science have created what they believe is the first comprehensive 3D model for mitosis using human stem cells. Previous models have characterized proteins involved in cell division using abnormal cells, but project co-director Susanne Rafelski says the Integrated Mitotic Stem Cell project — which includes images from some 2,000 mitotic cells and 15 structures within cells — captures how normal cells behave....

Supplement for joint pain linked to lower heart disease risk
By Maria Cohut Fact checked by Isabel Godfrey Glucosamine, a dietary supplement that people commonly take to ease joint pain and reduce symptoms of osteoarthritis, may lower the risk of cardiovascular problems, according to a study analyzing health data from over 400,000 participants. Information from the National Center for Complementary and Integrative Health shows that about 2.6% of...

Probe detects the mechanism for spread of metastatic cancer cells
A new fluorescent sensor developed by researchers from the University of Adelaide can detect migrating cancer cells and could be used to target medication to stop metastasis in aggressive cancers. Metastasis—the uncontrolled migration of cancer cells which creates new tumors at different locations in the body—is a major cause of cancer-related deaths. Research at the University of Adelaide has shown mammalian proteins...

Testosterone The Key To Unlocking Better Overall Health
Recent studies suggest that long-term sufferers of Cachexia may be in for some much needed good news. Experienced by as many as half of all cancer patients – and responsible for the deaths of around 22% – Cachexia may have met its match with new technologies on the horizon already proving successful in minimizing its energy-sapping...

How do we recall the past? New mechanism revealed
By Catharine Paddock PhD Fact checked by Jasmin Collier Following their study in rats, scientists have broken new ground in memory research. The finding concerns how the brain retrieves long-term memory and should open new avenues for investigating and treating Alzheimer’s disease and other causes of dementia. Researchers at the University of Nevada, Las Vegas have discovered that two brain...

Octopus-inspired wearable sensor
AMERICAN CHEMICAL SOCIETY Wearable electronics that adhere to skin are an emerging trend in health sensor technology for their ability to monitor a variety of human activities, from heart rate to step count. But finding the best way to stick a device to the body has been a challenge. Now, a team of researchers reports the development of...

COPD may strike women harder than men
by Steven Reinberg, Healthday Reporter Smoking is its leading cause, and while women report smoking less than men, those with COPD have more trouble breathing, more frequent flare-ups and a poorer quality of life, researchers found. “Physicians need to be aware that symptoms for women may be worse for a given level of lung function and that exacerbations may be more frequent,”...

A road map to stem cell development
Johns Hopkins Medicine researchers report they have created a method of mapping how the central nervous system develops by tracking the genes expressed in cells. The technique, demonstrated in mouse retinas for this study, follows the activity of the genes used by individual cells during development, allowing researchers to identify patterns in unprecedented detail. This precise...
