- Double Star with Weird and Wild Planet-forming Discs
Astronomers have found wildly misaligned planet-forming gas discs around the two young stars in the binary system HK Tauri. These new observations provide the clearest picture ever of protoplanetary discs in a double star. The new result also helps to explain why so many exoplanets ? unlike the planets in the Solar System ? came to have strange, eccentric or inclined orbits.
- Supportive moms and sisters boost female baboon's rank
A study of dominance in female baboons suggests that the route to a higher rank is to maintain close ties with mom, and to have lots of supportive sisters.
- Money talks when it comes to acceptability of 'sin' companies, study reveals
Companies who make their money in the 'sin' industries such as the tobacco, alcohol and gaming industries typically receive less attention from institutional investors and financial analysts. But new research shows social norms and attitudes towards these types of businesses are subject to compromise when their share price looks to be on the rise.
- Saving seeds the right way can save the world's plants
Exotic pests, shrinking ranges and a changing climate threaten some of the world's most rare and ecologically important plants, and so conservationists establish seed collections to save the seeds in banks or botanical gardens in hopes of preserving some genetic diversity. For decades, these seed collections have been guided by simple models that offer a one-size-fits-all approach for how many seeds to gather. A new study, however, has found that more careful tailoring of seed collections to specific species and situations is critical to preserving plant diversity.
- Dimly lit working environments: Correcting body clock is possible
Researchers have, for the first time, conducted a study under real conditions on the body clocks of members of an international polar research station. The researchers have shown that a particular kind of artificial light is capable of ensuring that their biological rhythms are correctly synchronized despite the absence of sunlight.
- Naltrexone may be effective in diminishing impulse control disorders in Parki...
Parkinson's disease (PD) patients may confront a common but largely unrecognized challenge: the occurrence of impulse control disorders (ICDs) such as compulsive gambling, sexual behavior, eating, or spending. A team of investigators conducted a pilot study and found that the opioid antagonist naltrexone may be an effective treatment for diminishing ICD symptoms in PD patients.
- Many depressed preschoolers still suffer in later school years
Children diagnosed with depression as preschoolers are likely to suffer from depression as school-age children and young adolescents, new research shows. The investigators followed 246 children, now ages 9 to 12, who were enrolled in the study as preschoolers when they were 3 to 5 years old. The children and their primary caregivers participated in up to six annual and four semiannual assessments. They were screened using a tool called the Preschool Feelings Checklist and evaluated using an age-appropriate diagnostic interview.
- Income a major driver of avoidable hospitalizations across New Jersey
The household income of its residents is the most important factor in whether a community has high or low rates of avoidable hospital visits -- conditions that could be better managed in a doctor's office or other health care settings if treated at an early stage, according to a report.
- Nature inspires a greener way to make colorful plastics
Long before humans figured out how to create colors, nature had already perfected the process -- think stunning, bright butterfly wings of many different hues, for example. Now scientists are tapping into those secrets to develop a more environmentally friendly way to make colored plastics. Their method uses structure -- or the shapes and architectures of materials -- rather than dyes, to produce colors.
- Exploring 3-D printing to make organs for transplants
Printing whole new organs for transplants sounds like something out of a sci-fi movie, but the real-life budding technology could one day make actual kidneys, livers, hearts and other organs for patients who desperately need them. Scientists are reporting new understanding about the dynamics of 3-D bioprinting that takes them a step closer to realizing their goal of making working tissues and organs on-demand.
