Bone loss that can lead to osteoporosis and fractures is a major problem for cancer patients who receive chemotherapy and radiation. Since the hormone estrogen plays an important role in maintaining bone health, bone loss is especially pronounced among postmenopausal women with breast cancer who are treated using therapies aimed at eliminating estrogen.
Men and children treated for other cancers also experience bone loss, suggesting that eliminating estrogen is not the only trigger leading to bone degeneration.
Researchers have used liquid metals to develop new bacteria-destroying technology that could be the answer to the deadly problem of antibiotic resistance.
The technology uses nano-sized particles of magnetic liquid metal to shred bacteria and bacterial biofilm - the protective "house" that bacteria thrive in - without harming good cells.
Published in ACS Nano, the research led by RMIT University offers a groundbreaking new direction in the search for better bacteria-fighting technologies.
As smokers know all too well, nicotine is highly addictive. It's hard to quit smoking, a habit that claims the lives of more than seven million people each year.
Smoking tobacco delivers nicotine to the neuroreceptors responsible for addiction, affecting the nervous system and causing addiction.
A new study, led by scientists from the University of Bristol, into the molecular interactions involved has revealed how these neuroreceptors respond to nicotine.
A wearable lithium drug monitor developed by the University of Surrey could change the lives of patients who suffer from bipolar and depression.
It is estimated that bipolar disorder affects one in 100 people and lithium remains the most effective long-term therapy for the condition. It is incredibly important to monitor lithium intake as it has a narrow therapeutic range and can be toxic once levels elevate above it.
A team of chemists at McMaster University has discovered an innovative way to break down and dissolve the rubber used in automobile tires, a process which could lead to new recycling methods that have so far proven to be expensive, difficult and largely inefficient.
The atmospheric concentration of methane, a potent greenhouse gas, has almost tripled since the beginning of industrialisation. Methane emissions from natural sources are poorly understood. This is especially the case for emissions from the Arctic Ocean.
Toronto - (January 13, 2020) Researchers at the Ontario Institute for Cancer Research (OICR) and the University Health Network (UHN) have discovered detailed new information about the subtypes of pancreatic cancer. A better understanding of the disease groups may lead to new treatment options and improved clinical outcomes for this lethal disease.
New research has found that two factors - an outdoor location and the presence of a weapon - have a significant bearing on the verdict of juries in cases of child stranger rape.
The study, the first of its kind to focus on real jury verdicts in cases of child stranger rape in England and Wales, was led by Criminal Psychologist Dr Samantha Lundrigan, of Anglia Ruskin University (ARU), and the findings have been published in the journal Child Abuse and Neglect.
New Rochelle, NY, January 13, 2020--Researchers are using caffeine to study how the brain processes information, and a new study shows the effectiveness of this approach. A placebo-controlled study in adults, which uses a simple Go/NoGo task, is published in Journal of Caffeine and Adenosine Research, a peer-reviewed journal from Mary Ann Liebert, Inc., publishers.

A minimally invasive procedure to treat a common foot and ankle disorder can reduce pain, recovery time, and postsurgery complications while improving functional outcomes, according to a report published in the journal Foot and Ankle Surgery.
The procedure treats insertional Achilles tendinopathy, a common and chronic orthopedic disorder in which patients experience pain at the Achilles tendon. The chronic degenerative condition can be particularly painful for athletes who perform push-off activities, such as basketball and soccer players.
Chestnut Hill, Mass. - An international team of physicists, materials scientists, and mechanical engineers has confirmed the high thermal conductivity predicted in isotopically enriched cubic boron nitride, the researchers report in the advance electronic edition of the journal Science.
Humans control their behavior in numerous ways, from stopping the urge pick at a scab to resisting the impulse to eat an entire box of chocolates. Suppressing undesired behavior, referred to as "cognitive control," traditionally has been linked to the functioning of the dorsal anterior cingulate cortex (dACC) in the front of the brain. Activity in dACC is observed across a variety of contexts, yet its function remains intensely debated in the field of cognitive neuroscience.
In birds, timing of arrival in a breeding area influences who ends up breeding and who does not. This aspect of behaviour, well-known in migratory birds, has now been studied for the first time in a non-migratory species, the blue tit. Researchers at the Max Planck Institute for Ornithology in Germany found that arrival time in the breeding area was an individual-specific and fitness-relevant trait for this resident bird species, as early-arriving individuals were more likely to breed in that year.
New Rochelle, NY, January 13, 2020--An in-depth look at the science of glycobiology and glycan diagnostics, and their promise in personalized medicine in the current post-genomic era are featured in a special issue of OMICS: A Journal of Integrative Biology, the peer-reviewed interdisciplinary journal published by Mary Ann Liebert, Inc., publishers.
Tropical Storm Claudia is battling wind shear as it continues moving away from Western Australia and through the Southern Indian Ocean. NASA-NOAA's Suomi NPP satellite provided forecasters with an image of the storm on January 13.
Visible imagery from NASA satellites help forecasters understand if a storm is organizing or weakening. The Visible Infrared Imaging Radiometer Suite (VIIRS) instrument aboard Suomi NPP provided a visible image of Claudia that showed the storm appeared elongated.
