Oregon marijuana: Lots of data, few to analyze and check it

To the beat of electronic dance music, men and women inside a slate-gray building harvested marijuana plants festooned with radio-frequency identification tags. In another room, an employee entered the tag numbers into a government database. The cannabis tracking system used by Avitas, a marijuana company with a production facility in Salem, is the backbone of

New approach to treating patients with stage IV Wilms tumor: Four-year overall survival increased 12 percent for patients with stage IV Wilms tumor with lung metastases

A new study showing significantly improved survival rates for patients with stage IV Wilms tumors with lung metastases was recently published in the Journal of Clinical Oncology. The outcomes of the study, “Treatment of Stage IV Favorable Histology Wilms Tumor With Lung Metastases: A Report From the Children’s Oncology Group AREN0533 Study,” will be a

Fetal immune system rejects the mother in preterm labor

Preterm labor, a common pregnancy complication, has long been a mystery to scientists. But a new study from UC San Francisco shows it may sometimes happen when the fetal immune system “wakes up” too early and begins to reject the mother, causing the uterus to start contracting. The researchers think the fetal immune system becomes

Study: California gun deaths declined between 2000 and 2015

Gun deaths have fallen in California over a 16-year period ending in 2015, driven largely by a decline in gang violence and falling homicide rates among black and Hispanic male victims, a recent study of firearm violence has found. Researchers at the University of California, Davis published their findings in the May issue of the

Stem cells from adults function just as well as those from embryos: Stem cells from elderly donors can be used for personalized treatment of age-related chronic and degenerative diseases, concludes a new review

Donor age does not appear to influence the functionality of stem cells derived from adult body tissues, concludes a new review. The analysis of research on induced pluripotent stem cells (iPSCs) finds that not only are typical signs of aging reversed in iPSCs, but cells derived from both older and younger donors show the same

Smart phone as a faster infection detector: Portable reader is nearly perfect in finding 12 common viral and bacterial diseases

Washington State University researchers have developed a low-cost, portable laboratory on a phone that works nearly as well as clinical laboratories to detect common viral and bacterial infections. The work could lead to faster and lower-cost lab results for fast-moving viral and bacterial epidemics, especially in rural or lower-resource regions where laboratory equipment and medical

Electrode shape improves neurostimulation for small targets

A cross-like shape helps the electrodes of implantable neurostimulation devices to deliver more charge to specific areas of the nervous system, possibly prolonging device life span, says research published in March in Scientific Reports. The shape, called “fractal,” would be particularly useful for stimulating smaller areas, such as deep brain structures or the retina, since

By 2040, artificial intelligence could upend nuclear stability

A new RAND Corporation paper finds that artificial intelligence has the potential to upend the foundations of nuclear deterrence by the year 2040. While AI-controlled doomsday machines are considered unlikely, the hazards of artificial intelligence for nuclear security lie instead in its potential to encourage humans to take potentially apocalyptic risks, according to the paper.

Soaking in hot tub improves health markers in obese women: Heat therapy appears to reduce inflammation, improve insulin resistance and lessen effects of polycystic ovary syndrome

According to new research, obese women with polycystic ovary syndrome (PCOS) may be able to improve their health outlook with a particularly enjoyable form of therapy: regular sessions in a hot tub. The research found that soaking in a hot tub several times per week for two months results in improved measures of cardiovascular health,

Detecting Alzheimer’s disease before it’s too late: Intervention long before the first signs of memory issues may be required to slow disease progression

The rate at which the protein beta-amyloid accumulates into the sticky plaques associated with Alzheimer’s disease (AD) is already slowing by the time a patient would be considered to have preclinical AD, according to a longitudinal study of healthy adults published in JNeurosci. The research suggests that anti-amyloid therapies would be most effective before individuals
