Childhood sibling dynamics may predict differences in college education
The effects of sibling relationships may go beyond childhood bickering and bonding, according to researchers who found that these relationships may predict similarities and differences in siblings' education later in life.
Virtual reality headsets significantly reduce children's fear of needles
Almost anyone can relate to being afraid of needles and injections. A pilot study is the first to use a 3D virtual reality headset to test this tool as a distraction method in a pediatric setting. Children were given the choice of a roller coaster ride, helicopter ride or a hot-air balloon ride. Results show that anticipated versus actual pain and fear were reduced in 94.1 percent of the pediatric study subjects.
Rising sea temperatures threaten survival of juvenile albatross
Changes in sea surface temperature affect the survival of albatross during their first year at sea, resulting in a reduced population growth rate when temperatures are warmer than the current average, a new study has revealed.
New 3D imaging analysis technique could lead to improved arthritis treatment
An algorithm to monitor the joints of patients with arthritis, which could change the way that the severity of the condition is assessed, has been developed by a team of engineers, physicians and radiologists.
Devastating plant virus is revealed in atomic detail
The complex 3D structure of one of the world's most lethal families of plant viruses has been revealed in unprecedented detail by scientists.
Genomics offers new treatment options for infants with range of soft tissue tumors
The genetic causes of a group of related infant cancers have been discovered by scientists. Whole genome sequencing of tumours revealed mutations which are targetable by existing drugs used to treat lung cancer and melanoma. The results have implications for clinical practice and the diagnosis of rare cancers in infants, and could lead to new, targeted treatment options for these children.
When it comes to weight loss in overweight and obese adults with knee osteoarthritis, more is better
Overweight and obese individuals with knee osteoarthritis can reduce pain and significantly improve function and mobility with weight loss. New research reveals that a 20% or more weight loss has the added benefit of continued improvement in physical health-related quality of life along with an additional 25% reduction in pain and improvement in function.
Constructing new tissue shapes with light
Constructing biological tissues, such as skin, muscle, or bone, in customized shapes is now one step closer. Researchers have succeeded in guiding the folding and thus shape of tissues with optogenetics: a technique to control protein activity with light.
Large outdoor study shows biodiversity improves stability of algal biofuel systems
A diverse mix of species improves the stability and fuel-oil yield of algal biofuel systems, as well as their resistance to invasion by outsiders, according to the new findings.
Nature programs could put a spring in your step
A new study shows that watching films set in a natural environment boosts body image.
When consumers don't want to talk about what they bought
One of the joys of shopping for many people is the opportunity to brag about their purchases to friends and others. But new research found one common situation in which people would rather not discuss what they just bought: when they're feeling like money is a little tight. In a series of studies, researchers found that consumers who felt financially constrained didn't want to talk about their purchases, large or small, with friends or strangers.
Laser-sonic scanner aims to replace mammograms for finding breast cancer
For women over 40, mammography is a necessary yet annoying procedure to endure every year or two. The technique, while valuable for reducing breast cancer deaths, is less than ideal because it exposes patients to X-ray radiation and requires their breasts to be painfully squished between plates. The plates flatten the breast so the X-rays can more easily pass through it and produce a clear image.
Algorithm speeds up process for analyzing 3D medical images
Researchers describe a machine-learning algorithm that can register brain scans and other 3D images more than 1,000 times more quickly using novel learning techniques.
Rare mutation of gene carried by Quebec family gives insight into how the brain is wired
The study of a Quebec family with an unusual gene provides novel insight into how our brain is built and, according to scientists, offers a better understanding of psychiatric disorders such as depression, addictions and schizophrenia.
'Slow earthquakes' on San Andreas Fault increase risk of large quakes
A detailed study of the California fault has discovered a new kind of movement that isn't accounted for in earthquake forecasting.
Novel combination as potential therapy for high-risk neuroblastoma
Researchers at VCU Massey Cancer Center in Richmond, Virginia, have identified a promising target to reverse the development of high-risk neuroblastoma and potentially inform the creation of novel combination therapies for the disease.
Bolder targets needed to protect nature for people's sake
Researchers argue that the world needs more diverse, ambitious and area-specific targets for retaining important natural systems to safeguard humanity.
Electrical wire properties of DNA linked to cancer
New research finds a connection between a cancer mutation and electron-mediated DNA repair.
Odors are perceived the same way by hunter-gatherers and Westerners
Previous research has shown the hunter-gatherer Jahai are much better at naming odors than Westerners. They even have a more elaborate lexicon for it. New research by language scientists show that despite these linguistic differences, the Jahai and Dutch find the same odors pleasant and unpleasant.
Scientists create continuously emitting microlasers with nanoparticle-coated beads
Researchers have found a way to convert nanoparticle-coated microscopic beads into lasers smaller than red blood cells. These microlasers, which convert infrared light into light at higher frequencies, are among the smallest continuously emitting lasers of their kind ever reported and can constantly and stably emit light for hours at a time, even when submerged in biological fluids such as blood serum.
