Overdose prevention and naloxone rescue among family members of people who use opioidsFamily members are often the ones who administer naloxone during an opioid overdose and should be considered as part of the larger response to help curb fatal overdoses. These findings demonstrate the important role that educating family members about overdoses and how to obtain and administer naloxone could play an important role in helping decrease the number of fatal opioid overdoses.

Modern metabolic science yields better way to calculate indoor carbon dioxideThe air we breathe out can help us improve the quality of the air we breathe in. But to do so, one needs a reliable way to calculate the concentration of carbon dioxide we produce indoors. Researchers have developed a new computation method that uses well-established concepts from the study of human metabolism and exercise physiology to significantly improve how this important data is derived.

Expert unravels disease that took the hearing of world-famos painterFrancisco Goya is the most important Spanish artist of the late 18th and early 19th century. In 1793, Goya, then 46, came down with a severe, undiagnosed illness. His hearing never returned. Now, a hearing expert has developed a diagnosis. She thinks Goya likely suffered from an autoimmune disease.
Success in the 3-D bioprinting of cartilageA team of researchers has managed to generate cartilage tissue by printing stem cells using a 3-D-bioprinter. The fact that the stem cells survived being printed in this manner is a success in itself. In addition, the research team was able to influence the cells to multiply and differentiate to form chondrocytes (cartilage cells) in the printed structure.

The finding adds to evidence for the intimate link between stem cells and cancer, and advances prospects for regenerative medicine and cancer treatments.
Female partners can help facilitate early melanoma detection in men over 50, research showsMen over 50 have a higher risk than the general population of developing melanoma, the deadliest form of skin cancer, so they need to keep a sharp eye out for signs of the disease. Many women in this age group, however, would attest that they’re more likely than their male partners to notice suspicious spots on the skin — which means women could help save their male partners’ lives by helping them spot skin cancer.
Artificial intelligence shows potential to fight blindnessResearchers have found a way to use artificial intelligence to fight a complication of diabetes that affects the eyes.
Study quantifies kidney failure risk in living kidney donorsResearchers have developed a risk calculator that estimates the risk of kidney failure after donation. Overall risk was low, but black race and male sex were associated with increased risks of developing kidney failure in living kidney donors. Older age was associated with greater kidney failure risk in nonblack donors, but not in in black donors. Higher BMI and a close biological relationship to the recipient were also associated with increased risks of kidney failure.

The tagging can be turned on like a switch, which enables researchers to acquire a snapshot of proteins being produced by a cell at a given time.
Food insecurity can affect your mental healthFood insecurity (FI) affects nearly 795 million people worldwide. Although a complex phenomenon encompassing food availability, affordability, utilization, and even the social norms that define acceptable ways to acquire food, FI can affect people's health beyond its impact on nutrition. A new study determined that FI was associated with poorer mental health and specific psychosocial stressors across global regions (149 countries), independent of individuals' socioeconomic status.
Left-handed people are more likely to have a slender faceIndividuals with a slender lower face are about 25 percent more likely to be left-handed. This unexpected finding was identified in 13,536 individuals who participated in three national surveys conducted in the United States. This association may shed new light on the origins of left-handedness, as slender jaws have also been associated with susceptibility to tuberculosis, a disease that has shaped human evolution and which today affects 2 billion people.

Daily platelet counts in children in the early stages of dengue can predict those most at risk for DSS, researchers report.
Resource availability drives person-to-person variations in microbes living in the bodyThe collection of microbial species found in the human body varies from person to person, and new research suggests that a significant part of this variation can be explained by variability in shared resources available to the microbes.
Tibetan people have multiple adaptations for life at high altitudesThe Tibetan people have inherited variants of five different genes that help them live at high altitudes, with one gene originating in the extinct human subspecies, the Denisovans.
Physical activity helps to counteract weight gain from obesity-causing gene variantPhysical activity can reduce the weight-gaining effects of the genetic variant that carries the greatest risk of obesity, report.
Neurons' faulty wiring leads to serotonin imbalance, depression-like behavior in miceA gene has been identified that allows neurons that release serotonin to evenly spread their branches throughout the brain. Without this gene, these branches become entangled, leading to haphazard serotonin distribution, and signs of depression in mice. These observations shed light on how neuronal wiring is critical to overall brain health, while also revealing a promising new research focus for psychiatric disorders associated with serotonin imbalance -- such as depression, bipolar disorder, schizophrenia and autism.
Diabetes app forecasts blood sugar levelsGlucoracle is a new app for people with type 2 diabetes that uses a personalized algorithm to predict the impact of particular foods on blood sugar levels.

Underdiagnoses of age-related macular degeneration, findings suggestApproximately 14 million Americans have age-related macular degeneration, and a new study suggests it may be underdiagnosed in primary eye care settings.
Nose2Brain: Better therapy for multiple sclerosisMedically active substances are normally distributed via the blood -- either directly by injection into the bloodstream or indirectly, for example through the digestive tract after oral administration. In many diseases, however, it is of decisive importance to transport the active substance as efficiently as possible to the required target site. An example of this is the treatment of multiple sclerosis, where the pharmaceutical agents have to produce their effect above all in the central nervous system. However, this is especially difficult to achieve in the usual way via the blood due to special protective mechanisms such as the blood-brain barrier.
Can early experiences with computers, robots increase STEM interest among young girls?Girls start believing they aren't good at math, science and even computers at a young age -- but providing fun STEM activities at school and home may spark interest and inspire confidence, suggests a new study.
Strong parent connections enhance children's ability to develop healthy response to stressChildren in low-income families have an increased chance of thriving when their caregiver relationships include certain positive characteristics, according to new research. Using data from more than 2,200 low-income families surveyed as part of the Fragile Families and Child Wellbeing Study, researchers found that school-age children who reported high levels of parent involvement and supervision were more likely to report behaviors associated with positive emotional development and social growth.
