Switching from unhealthy to healthier diet lowers depressive symptoms more than social support sessions
20 percent of Americans responsible for almost half of US food-related greenhouse gas emissions
Biophysicists have imaged the moment a photon sparks the first energy conversion steps of photosynthesis.
Toddlers learn nothing from YouTube videos. New study finds that two-year-olds enjoy the commercials more than the videos (and seem engaged with musical clips) but do not learn anything from YouTube.
A single intravenous infusion of ketamine led to a rapid decrease in suicidal ideations. Within a day, about 55% of individuals who received ketamine no longer had suicidal ideations compared to 20% who received placebo. This reduction in suicidal ideations lasted for at least 7 days.
Living abroad can clarify your sense of self. They found living abroad increases "self-concept clarity," the extent to which individuals' beliefs about themselves are clearly and confidently defined and consistent and stable over time.
A bat no bigger than a kiwi fruit logs distances of up to 100 kilometres on nightly round trips to its feeding grounds — the longest commute ever recorded for a nectar-feeding bat.
Published this week in the International Journal of Obesity, the study suggests that parents who underestimate the sugar content of everyday foods and beverages commonly included in children’s diets are exposing their children to an increased risk of obesity or overweight.
Read with them, watch with them. Toddlers that co-view with an engaged parent learn more words from videos than those that watch alone.
Using diamond, scientists build first continuous room-temperature solid-state maser - the microwave version of lasers. Possible applications include medical imaging, airport security scanners, improved bomb detection, and quantum computers.
The Effort Paradox: Prominent models indicate that effort is costly, and that we avoid it. A new series of studies show that this is only half the story. Humans and non-human animals alike tend to associate effort with reward and will sometimes select activities because they require effort
3D printer has for the first time combined several printing methods to produce devices out of multiple materials in a single print run. So far the machine has created basic electronic devices, but the technology brings us a step closer to printing complex equipment such as robots or smartphones
Wounds in the fetus can heal without scarring, a fact that has prompted scientists to design new biomaterials based on the properties of fetal skin. Now, a new type of nanofiber has been shown to heal wounds in mice faster and with less scarring than untreated wounds.

New linguistic analysis finds that Dravidian language family is approximately 4,500 years old
Mumps virus outbreaks in Europe and the U.S. are linked to waning effectiveness of the vaccine: the increase in cases are more consistent with the loss of efficacy over time, rather than incomplete protection against an evolving virus. An additional dose, however, may extend protection.
The most sustainable end-of-life option for paper cups used for hot beverages - A new study shows that recycled cups were shown to have a better environmental performance, while digestion and composting resulted in a higher net reduction in CO2 emissions, up to 5.4 kg CO2 eq. per 1000 collected cups

Sad and lonely people have the best read on human nature—they are more perceptive than others in understanding how we act in social groups, researchers say
A new study has found that the children of centenarians (people who live to 100 years old or more), who tend to have similar healthy aging patterns and long lives like their parents, are also much more likely than the general population to have a strong sense of purpose.
Do your share: Perception of fair division of housework linked to better sex among married individuals in midlife, according to new research.
The Hidden Footprint of Making All Farms Organic: eliminating synthetic fertilizer, and making up for both the yield gap and the shadow footprint, would require at least an extra Australia-sized amount of land — between 40% and 100% more agricultural land than the amount we use today.
Virus fished from pond cures man’s deadly antibiotic-resistant infection - The clinical success suggests promising strategy for fighting antibiotic resistance, according to a paper published in the journal of Evolution, Medicine, and Public Health.
An MIT-Made Robot Fish Will Study the World's Fragile Coral Reefs Unobtrusively: “You can start duplicating and make several of these robotic fish to use them almost like a network of sensors and cameras,”
More than one in 10 people who have never used class A drugs may have traces of cocaine or heroin on their fingertips, forensic scientists say. The scientists believe the participants became contaminated from banknotes, tables and other surfaces, as reported in the journal Clinical Chemistry.
Researchers discover a naturally occurring genetic variant that reduces the risk of chronic liver disease by up to 74%. A drug attempting recapitulate the effects of the genetic variant in the general population could enter the clinic within a year.

Experiments that ask children to draw a researcher show a greater proportion of women in sketches over time. In the 1960s and 1970s, 99.4% of children drew a male scientist. That proportion dropped to 72% between 1985 and 2016. By the 2010s, about one in three drawings portrayed a female scientist.
