Review study finds limited data on medical cannabis use in children
A systematic review of published studies on the use of medical cannabis in children and adolescents finds a notable lack of studies and a minimal number of the randomized, controlled trials needed to confirm the effectiveness of a treatment.
Scientists track ovarian cancers to site of origin: Fallopian tubes
Some scientists have suspected that the most common form of ovarian cancer may originate in the fallopian tubes, the thin fibrous tunnels that connect the ovaries to the uterus.
Biosimilar drugs could cut US health spending by $54 billion over next decade
Biosimilar drugs have been touted as one strategy to help curb the runaway costs of biologics that have advanced the treatment of illness such as rheumatoid arthritis and many cancers.
George Washington University report finds improving job outlook for new nephrologists
The American Society of Nephrology (ASN), the world's largest organization of kidney health professionals, released a new analysis of the future nephrology workforce, authored by George Washington University (GW) researchers.
Symptom burden may increase hospital length of stay, readmission risk in advanced cancer
Hospitalized patients with advanced cancer who report more intense and numerous physical and psychological symptoms appear to be at risk for longer hospital stays and unplanned hospital readmissions.
Electricity from shale gas vs. coal: Lifetime toxic releases from coal much higher
Despite widespread concern about potential human health impacts from hydraulic fracturing, the lifetime toxic chemical releases associated with coal-generated electricity are 10 to 100 times greater than those from electricity generated with natural gas obtained via fracking, according to a new University of Michigan study.
Study finds shortcomings in Canadian regulations governing use of sugar claims
A new study published today in Applied Physiology, Nutrition, and Metabolism, reports that prepackaged food and beverages labelled with claims such as 'no added sugar' or 'reduced in sugar' can have lower sugar levels than products without sugar claims but may not have notable reductions in calories and some can contain amounts of sugar considered in 'excess' by the World Health Organization.
Taming 'wild' electrons in graphene
Graphene -- a one-atom-thick layer of the stuff in pencils -- is a better conductor than copper and is very promising for electronic devices, but with one catch: Electrons that move through it can't be stopped.
Advanced cancer patients' physical emotional burdens linked lengthy hospital stays
New research indicates that hospitalized patients with advanced cancer experience many physical and psychological symptoms, and that patients dealing with a higher burden of these symptoms have longer hospital stays and a greater risk for unplanned hospital readmissions.
Birds without own brood help other birds with parenting, but not selflessly
Birds will sometimes care for the offspring of other birds of their own species if they anticipate future benefits.
Genetic testing helps determine safest dose of blood thinner for joint surgery patients
A new five-year study of nearly 1,600 patients finds that genetic testing can help determine the safest dose of the blood thinner warfarin, with fewer side effects, in patients undergoing joint replacement surgery.
Fifty simulations of the 'Really Big One' show how a 9.0 Cascadia earthquake could play out
The largest number yet of detailed simulations for how a Cascadia Subduction Zone earthquake might play out provides a clearer picture of what the region can expect when the fault unleashes a 9.0 earthquake.
Routes out of isolation for Yellowstone grizzlies
An interagency team of Montana and Wyoming biologists models possible routes to a reunion of the Yellowstone and Northern Continental bear populations through adventurous male immigrants.
Photocatalytic reduction of aqueous mercury (II) using hybrid WO3-TiO2 nanotubes film
Hybrid WO3-TiO2 nanotube films were successfully formed via electrochemical anodization at applied potential of 40 V in ethylene glycol organic electrolyte containing 1 vol % of hydrogen peroxide (H2O2) and 0.3 wt % ammonium fluoride (NH4F) by varying the anodization time from 15 up to 120 minutes.
Depression strongly linked to higher long-term risk of early death for both women and men
Despite increased awareness about mental illness, depression remains strongly linked to a higher risk of early death -- and this risk has increased for women in recent years -- according to results from the 60-year Stirling County Study published in CMAJ (Canadian Medical Association Journal).
Personalizing human-robot interaction may increase patient use - Ben-Gurion U.
'Determining the elements in the interaction that make users more motivated to continue is important in designing future robots that will interact with humans on a daily basis.'
Solution to mysterious behavior of supercooled water
Japan-based researchers developed a model to explain mysterious breakdown of Stokes-Einstein relationship in supercooled water.
Irregular heartbeat linked to higher thyroid hormone levels
Individuals with higher levels of thyroid hormone (free thyroxine or FT4) circulating in the blood were more likely than individuals with lower levels to develop irregular heartbeat, even when the levels were within normal range.
Genetic rescue boosts recovery of Australia's endangered mountain pygmy possums
For the first time, a breeding technique known as genetic rescue has been shown to increase population numbers and survival rates of the endangered mountain pygmy possum, now at their highest numbers since 1996.
New study suggests psychedelic drugs may reduce criminal behaviour
Newly published research suggests that common psychedelic drugs -- such as magic mushrooms, LSD and mescaline (a substance derived from the peyote cactus) -- may reduce criminal offences.
African-Americans live shorter lives due to heart disease and stroke
African-Americans carry a higher burden of cardiovascular diseases compared with white Americans.
Novel transdisciplinary study uncovers microbes that may one day deter major grape disease
Researchers at the University of California-Riverside (UCR) conducted a novel transdisciplinary study to characterize the microbial communities within the vascular system of grapevines and their connections with Pierce's disease, an economically significant disease of the California grape industry.

Manipulation
We think we're the ones who control what we see, read, think and remember. But is that true? Who decides? And who should decide? This hour, TED speakers reveal just how easily we can be manipulated. Guests include design ethicist Tristan Harris, MSNBC host Ali Velshi, psychologist Elizabeth Loftus, and neuroscientist Steve Ramirez.

#444 The V-Word (Rebroadcast)
This week, we're looking at the social and biological science of female sex organs. We'll talk to Dr. Anthony Atala, director of the Wake Forest Baptist Medical Center Institute for Regenerative Medicine, about the creation and use of lab-grown vaginas. Biology professor Marie Herberstein exposes the bias against female genitalia in scientific studies. And science writer Emily Anthes tells us about the history and promising future of female condoms.
