Researchers have succeeded in unveiling the microscopic mechanism of AHE release in water.
When cells divide, chromosomes need to be evenly segregated. This equal distribution is important to accurately pass genetic information to the next generation. Abnormal segregation can cause cell death or diseases like Down syndrome and cancer. Filamentous spindle fibers must bind to the chromosome centromere to divide equally. For the spindle fiber to be correctly joined, the chromosome must have heterochromatin. However, the mechanism for forming this structure has not been sufficiently clarified.
'Technophobes' -- people who fear robots, artificial intelligence and new technology that they don't understand -- are much more likely to be afraid of losing their jobs due to technology and to suffer anxiety-related mental health issues, a Baylor University researcher says.
A medical team has developed a way to effectively provide a large group of people with basic knowledge and skills to locate and use bleeding control equipment to stop life-threatening bleeding in severely injured people.
Researchers at Bascom Palmer Eye Institute, part of the University of Miami Miller School of Medicine, have identified a new molecule that induces the formation of abnormal blood vessels in the eyes of diabetic mice. The study, 'Secretogranin III as a disease-associated ligand for antiangiogenic therapy of diabetic retinopathy,' which will be published March 22 in The Journal of Experimental Medicine, suggests that inhibiting this molecule may prevent similarly aberrant blood vessels from damaging the vision of not only diabetics, but also premature infants.
Patients who underwent ambulatory breast reconstruction and used a mobile app for follow-up care had fewer in-person visits during the first 30 days after the operation without affecting complication rates or measures of patient-reported satisfaction, according to a study published online by JAMA Surgery.
People bereaved by the suicide of a spouse were at increased risk for mental and physical disorders, suicidal behavior, death and adverse social events, according to a nationwide study based on registry data conducted in Denmark and published online by JAMA Psychiatry.
People who lose a partner to suicide are at increased risk for a number of mental and physical disorders, including cancer, depression, herniated discs and mood disorders than those in the general population, new Johns Hopkins Bloomberg School of Public Health research suggests.
A team of researchers led by University of Utah bioengineering professors has discovered that damage to collagen, the main building block of all human tissue, can occur much earlier at a molecular level from too much physical stress. This could be especially helpful for some who want to know earlier if they are developing diseases such as arthritis or for athletes who want to know if repeated stress on their bodies is taking a toll.
Many people choose their spouse based on shared values and interests. But in China, another important, relatively unknown factor plays a role: hukou, and it may be contributing to growing socioeconomic disparity in the country's largest city, according to a new UBC study.
A new study of older US adults conducted by researchers from the Monell Center and collaborating institutions reports that a woman's social life is associated with how well her sense of smell functions. The study found that older women who do less well on a smell identification task also tend to have fewer social connections.
Surfaces that have been coated with rare earth oxides develop water-repelling properties only after contact with air. Even at room temperature, chemical reactions begin with hydrocarbons in the air. In the journal Scientific Reports, researchers from the University of Basel, the Swiss Nanoscience Institute and the Paul Scherrer Institute report that it is these reactions that are responsible for the hydrophobic effect.
A set of Google Street View mapping cars, specially equipped with cutting-edge methane analyzers, are allowing Colorado State University researchers to 'see' invisible methane leaks from natural gas lines beneath our streets. The technical and computational challenges of measuring methane, and the complex methodologies used to collect, analyze and publicize the data, are detailed in a new paper in the journal Environmental Science and Technology.
Finding and fixing natural gas leaks is a persistent challenge for utilities across the country. In addition to the serious safety considerations, leaking natural gas -- which is mostly methane -- also contributes the potent greenhouse gas to the atmosphere. To help address this problem, scientists teamed up with Google Earth Outreach to outfit Street View cars with methane analyzers to map leaks. They report their findings in the ACS journal Environmental Science & Technology.
The discovery of a new species of hard coral, found on Lord Howe Island, suggests that the fauna of this isolated location in the Tasman Sea off south eastern Australia is even more distinct than previously recognised. Even though the World Heritage-listed site has been long known for its biodiversity, the new species, recently described in the open access journal ZooKeys, is the first coral known to live exclusively in the region.
The people one dates share many similarities -- both physically and personality-wise -- a new University of California study has found.
A large prospective study in 309 adolescent boys and girls underscores the importance of physical activity for developing bone strength during growth. Adolescents who participated in moderate to intense physical activity during growth spurt years exhibited greater bone mass in areas that contribute to superior bone strength. The study also found mixed effects of sedentary time.
A new study indicates that early experiences of environmental harshness, in combination with a child's temperament, can influence later problem-solving abilities.
Previously, mainly women with a history of cancer were referred for genetic testing, but as awareness has grown, more low-risk women are undergoing BRCA testing. A new study in the American Journal of Preventive Medicine found that the proportion of women without a history of cancer who underwent BRCA testing rose sharply from 24.3% in 2004 to 61.5% in 2014.
Although anti-inflammatory treatments are quite effective at reducing symptoms in patients with Crohn's disease and ulcerative colitis, the mucosal lining of the intestine often remains ulcerated, and many patients still ultimately require surgery. Because of this, the goal of treatment is shifting towards mucosal healing rather than just symptom relief.
