Exclusive: preoccupation with conflict fosters insecurity, populism and trust deficit, says Johan Galtung

By Christian Jarrett. Trait self-control and effective strategy use may represent two separate routes to greater persistence.

Passerine's fixed-wing drones can take off (and land) using a pair of legs.

Once the Saints game is over Sunday night, you can experience yet another phenomenon that is out of this world.

Kiwi children who spend too much time on screens are becoming sicker, more obese, and more likely to be hyperactive, according to a new study. Commissioned by the Ministry of Social Development, the study also showed young children who exceeded the recommended electronic screen time had poorer motor skills than those who were less exposed to the technology.

A scientist at NASA animated how long it takes light to travel around Earth, to the moon, and to Mars. The movies show just how slow light can be.

Many Americans would welcome some traits of the island’s free, universal health care system.

Last spring, Marketplace host Charlsie Agro and her identical twin sister, Carly, bought DNA ancestry kits from five of the most popular companies in the industry. Find out why some of the results they received left a team of computational biologists at Yale University baffled.

Moderate earthquakes aren’t releasing enough stress along the region’s faults. They’re actually making it worse.

Algorithms are increasingly being used to make ethical decisions. Perhaps the best example of this is a high-tech take on the ethical dilemma known as the trolley problem: if a self-driving car cannot stop itself from killing one of two pedestrians, how should the car’s control software choose who live and who dies?

Ten times brighter than an LED, but won’t blind oncoming traffic.

Now that the DSM lists severe hoarding as a disorder apart from OCD, psychologists are asking what explains its prevalence.

Drones have a fundamental design problem. The kind of drone that can carry large payloads at high speeds over long distances is fundamentally different from the kind of drone that can take off and land from a small area. In very simple terms, for the former, you want fixed wings, and for the latter, you want rotors.

New research suggests that humpback whale populations in the Atlantic and Indian Oceans are picking up musical ideas from one another, and incorporating the new phrases and themes into their songs. According to the study, published November 28, 2018, in the peer-reviewed journal Royal Society Open Science, humpback whale populations in different Southern Hemisphere ocean basins (the South Atlantic and Indian Oceans) sing similar song types, but the amount of similarity differs across years.

The story of Dr. Rapp

In literature, characters that smoke are often described as haggard and older looking, with facial features that are associated with worn leather. While these depictions arguably carry over into reality, what is for certain is that the association between smoking, cancer, and cardiovascular disease is strong. Unfortunately, however, the connection between smoking and biological aging has been less clear. Yet, a new study from an international team of investigators led by scientists at Insilico Medicine may change how smoking is evaluated at the biochemical level.

The next great insect repellent might come from a strain of bacteria that lives inside a common parasitic worm. A study published Wednesday in Science Advances has found that a compound derived from these bacteria is three times more potent than DEET in repelling mosquitoes. More research must be done to demonstrate its safety, but this bacterial chemical could play an important role in the fight against mosquito-borne illness.

Women that underwent extreme physical training and completed a transantarctic expedition did not show any more negative health effects than would be expected in men, according to a study presented at the Society for Endocrinology annual conference in Glasgow. The study is the first to suggest that women are not more susceptible to the negative effects of physical exertion and, that with appropriate training and preparation, can be as resilient as men in undertaking arduous physical activity.
